Technical Field

The invention relates to a forming clamp of a sound production obstacle treatment tool and a method for bending a front surface piece of the sound production obstacle treatment tool.

Background

In order to improve spastic sound-production disorders such as the vocal cords not vibrating due to excessive glottic closure, for example, a sound-production disorder treatment tool shown in patent document 1 below is proposed. The therapeutic device for sound emission disorder disclosed in patent document 1 includes: two holding parts made of titanium for holding the cut ends on both sides of the cut thyroid cartilage; and a bridge portion made of titanium, bridging the two clip portions, and maintaining an incision interval of the incised thyroid cartilage. The clip has a front sheet disposed on the front surface side of the cut thyroid cartilage and a back sheet disposed on the back surface side of the thyroid cartilage.

When using the treatment tool, the front piece of the clamping part is bent first. Thereby, the shape of the front sheet is made to follow the shape of the thyroid cartilage of the portion where the treatment tool is placed. Then, the center of the thyroid cartilage is cut, the cut end of the thyroid cartilage is expanded with forceps or the like, the holding section is fitted to the expanded cut ends facing each other, and the forceps or the like is removed. In this case, the expanded cutting ends are elastically restored in the closing direction, and thus the treatment tool is firmly fixed between the cutting ends.

Further, a suture thread is passed through a hole formed in the front panel to hold a treatment tool or the like, and the treatment tool is sutured to the thyroid cartilage. Thereby, the provided treatment tool is more reliably prevented from being displaced at the cut-off end. In this way, the treatment tool can be reliably fixed between the expanded thyroid cartilage.

Disclosure of Invention

Technical problem to be solved by the invention

As described above, before the treatment tool is set on the thyroid cartilage of the patient, the front surface sheet of the holding portion needs to be bent in advance so as to follow the front surface of the thyroid cartilage. However, since the front sheet has the hole formed therein, when a doctor or the like manually folds the front sheet using a conventional tool such as a forceps, the front sheet may be bent along a line passing through the hole. In this case, after the treatment tool is set on the thyroid cartilage, stress may be concentrated at a portion bent at a line passing through the hole, and the front sheet may be broken at the line passing through the hole.

Accordingly, an object of the present invention is to provide a jig for molding a sound-emitting obstacle treating tool, which can bend a front surface sheet at a position not passing through a hole.

With this configuration, it is possible to cope with a plurality of treatment tools having different positions and sizes of the holes of the front sheet.

The corner portion of the molding jig of the present invention, which changes the width of the holding portion covering the front sheet among the pair of holding portions, may be cut out in a substantially cylindrical shape.

In the molding jig of the present invention, a projection to be inserted into the hole may be formed on any one of the opposed holding surfaces of the pair of holding portions.

According to this structure, the forming jig can be easily aligned with the front panel.

The clip portion of the molding jig of the present invention may be provided with a housing portion in which the bridge portion can be disposed.

According to this configuration, the degree of freedom in the arrangement direction of the front sheet with respect to the nip portion can be improved.

The clamp portion of the molding jig of the present invention includes a pressing member that presses the front sheet clamped by the clamp portion to bend the front sheet.

According to this structure, the bending operation can be completed with one forming jig.

In the molding jig of the present invention, a concave portion into which a part of the front sheet can be fitted may be formed in the holding surfaces of the pair of holding portions facing each other.

Detailed Description

Embodiments of a molding jig for a sound-emitting disorder treatment tool according to the present invention will be described with reference to the drawings.

A jig for molding a sound-emitting disorder treatment tool (hereinafter referred to as a "treatment tool") according to a first embodiment of the present invention is a jig for bending a front surface sheet 1a of a treatment tool X shown in fig. 1 at a predetermined angle, for example, as shown in fig. 2.

First, the treatment tool X to be molded, which constitutes the molding jig of the present application, will be described.

As shown in fig. 1, the treatment tool X has: a plurality of (in the present embodiment, a pair of) holding sections 1, 1 each having a front sheet 1a and a rear sheet 1b, respectively fitted to mutually opposed cut ends 12, 12 of a cut thyroid cartilage 11 shown in fig. 2; and a bridge portion 2 connecting the plurality of nip portions 1, 1.

The front sheet 1a is formed in a substantially rectangular plate shape in plan view, and has end surface portions 1c and surface contact portions 1 d. The end surface portion 1c is located on the base end side in the longitudinal direction of the front sheet 1a, and constitutes a portion bent to face the cut end surface 12a of the thyroid cartilage 11 shown in fig. 2. The front contact portion 1d is located on the distal end side of the end surface portion 1c of the front sheet 1a, and constitutes a portion disposed on the front surface 11a of the thyroid cartilage 11.

The front sheet 1a has a plurality of (2 in the present embodiment) holes 3 formed therein at intervals in the longitudinal direction. These holes 3, 3 are formed to have a size of 1.0mm to 2.0mm so that a suture thread (not shown) can be inserted therethrough, as well as a size of 1.0mm to 2.0 mm.

As shown in fig. 1 and 2, the back sheet 1b is a portion bent from the end surface 1c of the front sheet 1a toward the back surface 11b of the thyroid cartilage 11 shown in fig. 2.

The front sheet 1a and the rear sheet 1b are integrally formed to constitute a nip portion 1, and the entire nip portion 1 is formed in a substantially J shape (inverted J shape).

In the holding section 1, the length of the front sheet 1a may be sufficient to hold the thyroid cartilage 11 and may be a length that is sufficient to conform to the shape of the thyroid cartilage 11, and specifically, the length of the front sheet 1a is preferably set to about 8mm to 12 mm. The back sheet 1b is preferably formed to have a length from the edge of the cut end 12 of the thyroid cartilage 11 to the edge of the soft tissue 40 located below the thyroid cartilage 11, and more specifically, the length of the back sheet 1b is preferably about 1.5mm to 3.5 mm.

As shown in fig. 2, the holding section 1 is provided in a pair in bilateral symmetry so that the front surface sheet 1a is disposed on the front surface 11a side of the thyroid cartilage 11 and the cut end surface 12a, and the rear surface sheet 1b is disposed on the rear surface 11b side of the thyroid cartilage 11 and can be fitted into the cut ends 12, 12 of the thyroid cartilage 11 facing each other. The pair of nip portions 1, 1 are connected by a bridge portion 2.

As shown in fig. 1, the bridge portion 2 is a portion connecting the clip portions 1, and connects the clip portions 1 at an intermediate portion in the extending direction of the end surface portion 1 c. The length (D) of the bridge section 2, i.e., the distance D between the two clip sections 1, 1 corresponds to the distance between the cut ends 12, 12 of the enlarged thyroid cartilage 11 shown in fig. 2, and varies depending on the symptoms of the patient suffering from the dysphonia, the body size of the patient, and the phonic state, but is generally set in the range of 2 to 6 mm.

The clip portion 1 and the bridge portion 2 are each made of titanium.

The titanium metal used for the treatment tool X to be used in the molding jig 20A is not limited to titanium as a pure metal, and includes titanium alloys used for artificial bones, artificial joints, and artificial tooth roots as a metal material for living bodies. Specifically, Ti-6Al-4V or the like known as a titanium alloy excellent in biocompatibility not containing Ni indicated to have carcinogenicity and cause allergy can be used. In order to prevent abrasion or liquation, titanium or a titanium alloy obtained by surface modification of titanium or a titanium alloy by injecting N or C ions may be used.

The distance t between the front contact portion 1d and the rear piece 1b (the width of the end surface portion 1 c) is preferably slightly larger than the thickness of the thyroid cartilage 11 shown in fig. 2, and more specifically, is preferably about 2 to 4 mm. If the interval t is smaller than the thickness of the thyroid cartilage 11 shown in fig. 2, the thyroid cartilage 11 is tightened, and the clip portion 1 continuously presses the thyroid cartilage 11 for a long time, which may cause abrasion and damage to the thyroid cartilage 11. On the other hand, if the interval t between the front contact portion 1d and the rear surface piece 1b is excessively larger than the thickness dimension of the thyroid cartilage 11, it is substantially difficult to clamp the thyroid cartilage 11 because the clamping portion 1 is easily displaced (slid) with respect to the thyroid cartilage 11.

Next, the structure of the molding jig 20A will be described.

As shown in fig. 3 or 4, the molding jig 20A includes a pair of holding portions 21a, 21b that sandwich the front sheet 1a so as to cover both the hole 3 on the base end side of the front sheet 1a and the front and back surfaces around the hole. The pair of holding portions 21a and 21b facing each other described above constitute a nip portion 22.

As shown in fig. 4, the holding portions 21a and 21b are each formed in a rectangular plate shape from a material such as metal or highly rigid synthetic resin. As shown in fig. 5, the side edge S of the holding portion 21 is formed substantially linearly. These holding portions 21a and 21b are connected at one end in the longitudinal direction by a hinge 23. The holding portion 21a serves as a movable-side holding portion 21a that pivots via the hinge 23, and the holding portion 21b serves as a fixed-side holding portion 21 b.

The fixed-side holding portion 21b and the movable-side holding portion 21a are formed so as to overlap each other so as to provide a space (tolerance) that can reliably hold the front surface sheet 1a of the treatment tool X by sandwiching the front surface sheet 1a of the treatment tool X from the thickness direction of the front surface sheet 1a of the treatment tool X.

As shown in fig. 4 and 5, a protrusion 25 is formed on the holding surface 24b of the fixed-side holding portion 21b that contacts the front sheet 1a, and the protrusion 25 can be inserted into the hole 3 of the front sheet 1a shown in fig. 1. The projection 25 is formed to match the shape and size of the hole 3, and is provided to be hard to swing in the horizontal direction in a state where the projection 25 is inserted into the hole 3. Further, a locking portion 26 is provided at the tip of the fixed-side holding portion 21b, and the locking portion 26 is used to hold the state in which the movable-side holding portion 21a is superimposed. The locking portion 26 is fixed to the tip of the movable-side holding portion 21a that overlaps the fixed-side holding portion 21b by rotating, and constitutes a stopper that does not cause the movable-side holding portion 21a to rotate accidentally. Further, the locking portion 26 is not essential.

A recess 27 for fitting the protrusion 25 is formed in a position corresponding to the protrusion 25 on the holding surface 24a of the movable-side holding portion 21a in contact with the front surface piece 1 a. When the protrusion height of the protrusion 25 is equal to or less than the thickness of the front sheet 1a, the recess 27 may be absent.

The width dimensions of the movable-side holding portion 21a and the fixed-side holding portion 21b are not particularly limited as long as they can cover the hole 3 on the base end side of the front sheet 1a and the periphery thereof and position the side edge S between the holes 3, but for example, it is preferable that the dimension in the longitudinal direction is 5mm to 60mm, and the dimension in the short-side direction is 2.5mm to 5 mm. It is preferable that the movable-side holding portion 21a and the fixed-side holding portion 21b are set to be 0.1mm or more and 0.4mm or less (allowance for insertion of the front sheet 1a) with respect to each other.

Next, the method of using the molding jig 20A, and the operation, function, and effect thereof will be described.

When the molding jig 20A is used, as shown in fig. 4 or 5, the movable-side holding portion 21a is rotated and expanded, and the front sheet 1a is placed in the fixed-side holding portion 21b with the hole 3 on the base end side of the front sheet 1a aligned with the protrusion 25 of the fixed-side holding portion 21b so that the longitudinal direction of the front sheet 1a and the longitudinal direction of the fixed-side holding portion 21b intersect substantially perpendicularly.

Then, as shown in fig. 3, the movable-side holding portion 21a is rotated to overlap the movable-side holding portion 21a and the fixed-side holding portion 21b with the topsheet 1a interposed therebetween, and the movable-side holding portion 21a is fixed to the fixed-side holding portion 21b by the locking portion 26.

In this way, the hole 3 on the proximal end side of the front sheet 1a in which the treatment tool X held by the molding jig 20A is formed is covered by the molding jig 20A, and the distal end of the front sheet 1a protrudes from the side edge S of the holding portion 21.

When the front surface sheet 1a protruding from the molding jig 20A is held and bent in this state, the nip 22 is formed of a material having high rigidity, and therefore the front surface sheet 1a is bent at a position along the side edge S of the nip 22 without being bent around the hole 3 covered by the nip 22.

Therefore, the following effects can be achieved: it is possible to prevent the front sheet 1a from being broken at a portion of the front sheet 1a having low rigidity by bending the front sheet 1a on a line passing through the hole 3.

In the present embodiment, the case where the side edge S of the holding portion 21 is set between the holes 3, 3 of the front sheet 1a and the holes 3, 3 are folded as shown in fig. 2 is exemplified, but the front sheet 1a is preferably folded so that two portions, i.e., the base end portion of the front sheet 1a surface contact portion 1d between the bridge portion 2 and the hole 3 closest to the bridge portion 2 and between the holes 3, 3 are folded. When the front piece 1a is folded at two positions, i.e., the proximal end portion of the front abutting portion 1d and the vicinity of the center of the front abutting portion 1d between the holes 3 and 3, the front piece 1a can be easily fitted to the front surface 11a of the thyroid cartilage 11, and the front piece 1a can be more gently bent.

When the front sheet 1a is to be bent, the front sheet 1a may be sandwiched between the front end sides protruding from the forming jig 20A by another forming jig 20A, and the holes 3 and 3 may be bent by holding the forming jigs 20A and 20A.

Next, a molding jig 20B according to a second embodiment of the present invention will be described with reference to fig. 6 and 7.

In the present embodiment, the same points as those of the molding jig 20A of the first embodiment will not be described, and the points different therefrom will be mainly described.

As shown in fig. 6, the molding jig 20B of the present embodiment differs from the molding jig 20A of the first embodiment in that the interval between the holding portions 21a and 21B facing each other is fixed, and neither of the holding portions 21a, 21B rotates about the base end portion 29.

The holding portions 21a and 21b are formed in a shape of a single long rectangular plate-like body bent so as to leave a space K equal to or slightly smaller than the thickness dimension of the front sheet 1a of the treatment tool X.

The tip of the holding portion 21a where the protrusion 25 is not provided is bent, so that the front sheet 1a is easily inserted.

The holding portion 21a and the holding portion 21b are integrally formed and fixed at the base end portion 29, and can be biased inward.

The holding portion 21b is formed with a recess 45 into which the front sheet 1a can be fitted.

With this configuration, when the front sheet 1a of the treatment tool X is inserted between the holding portions 21a and 21b, the holding portions 21a and 21b are biased to both the front surface and the back surface of the front sheet 1a without being expanded by the thickness of the front sheet 1a, and a stronger biasing force is applied until the front sheet 1a passes over the protrusion 25 after approaching the protrusion 25. Then, the holding portions 21a and 21b hold the front sheet 1a by urging the front sheet 1a to the front surface and the back surface again by fitting the protrusions 25 into the holes 3 when the holes 3 of the front sheet 1a come close to the protrusions 25 by the urging force.

Therefore, the forming jig 20B not only achieves the same actions, functions, and effects as those of the forming jig 20A, but also achieves the following effects when bending the front sheet 1 a: the front sheet 1a can be firmly held without using the locking portion 26 for fixing the tips of the holding portions 21 to each other.

In addition, the molding jig 20B can achieve the following effects: the operation of rotating the holding portion 21a is omitted, and the front sheet 1a can be simply held by merely inserting the front sheet 1a between the holding portions 21a, 21 b.

Further, since the hole 3 of the front sheet 1a is engaged with the projection 25 of the holding portion 21b, the following effects can be achieved: the holding portions 21a, 21b can be reliably positioned to the front sheet 1a, and the front sheet 1a can be reliably bent between the holes 3, 3 even if one hole 3 is covered by the holding portion 21a and cannot be seen.

In addition, in the clamp portion 22 of either the molding jig 20A of the first embodiment or the molding jig 20B of the second embodiment, an operation portion 30B that is easily grasped by a human hand may be attached to the base end portion 29 of the clamp portion 22. The operating portion 30B may have any shape as long as it is a shape that facilitates the operation of the clip portion 22, but may be formed into a rod shape that can be easily grasped by the entire palm or palm and fingertips of a person who operates the molding jig 20A or 20B, for example.

Next, a molding jig 20C according to a third embodiment of the present invention will be described with reference to fig. 8 to 10.

Note that, since the molding jig 20C of the present embodiment is an application example of the molding jig 20B of the second embodiment, the description thereof will be omitted for the same points as those of the second embodiment, and the description will be mainly given of the different points.

As shown in fig. 8 or 9, the molding jig 20C is the same as the molding jig 20B of the second embodiment in that the holding portion 21a and the holding portion 21B of the clip portion 22 are integrally molded and the holding portion 21a and the holding portion 21B are fixed to each other. However, the molding jig 20C is different from the molding jig 20B mainly in the following points.

That is, in the holding portion 21b (hereinafter, referred to as "lower holding portion 21 b") of the molding jig 20C on the surface side receiving the front sheet 1a, the holding portion 21a (hereinafter, referred to as "upper holding portion 21 a") is provided at both one end portion of the lower holding portion 21b and an end portion opposite to the one end portion. The lower holding portion 21b is formed in a substantially flat plate shape so as to be able to receive at least a part of both the front sheets 1a and 1 a. The portion other than the upper holding portion 21a and the lower holding portion 21b for folding the top sheet 1a is an operation portion 30C for grasping and operating the molding jig 20C.

The following specifically describes the difference between the molding jig 20C and the molding jig 20B.

As shown in fig. 8, the molding jig 20C includes: a lower holding portion 21b having a substantially rectangular shape in plan view; a connecting portion 33 rising from an end along one side of the lower holding portion 21 b; and upper holding portions 21a and 21a extending from the upper end of the coupling portion 33 in a direction facing the lower holding portion 21 b.

The lower holding portion 21b is formed in a substantially rectangular flat plate shape having a size capable of providing at least a part of each of the front sheets 1a and 1 a. Specifically, the lower holding portion 21b is formed in such a size that, when the pair of front sheets 1a and 1a are placed and the front end of the front sheet 1a is projected from a portion to be bent, at least a part of the other front sheet 1a is positioned on the lower holding portion 21 b. In this case, the entire other front sheet 1a may be arranged on the lower holding portion 21b, or the tip of the other front sheet 1a may protrude from the lower holding portion 21 b.

The connecting portion 33 forms a side wall standing at substantially right angles from an end portion along one side of the lower holding portion 21b, and forms a certain gap between the lower holding portion 21b and the upper holding portion 21 a. A side surface 34a of the coupling portion 33 facing the distal end direction of the upper holding portion 21a is vertically raised to form a part of a housing portion 34 described later, and receives an end portion of the treatment tool X when the treatment tool X is inserted.

The upper holding portions 21a, 21a protrude in a plate shape from upper end portions of both ends of the connecting portion 33 in a direction along one side (i.e., a direction in which the front sheets 1a, 1a are arranged) so as to face the lower holding portion 21 b. That is, the upper holding portions 21a and 21a are provided at a distance from each other. The upper holding portions 21a and the coupling portion 33 are formed in a substantially U shape in plan view. The bridge portion 2 can be disposed in the housing portion 34 formed in a shape cut out by the upper holding portions 21a and the coupling portion 33.

The holding surfaces 31a and 31a of the upper holding portions 21a and 21a (i.e., the surfaces facing the lower holding portion 21b) are formed on the same surface, and a groove K penetrating in one direction is formed between the upper holding portion and the lower holding portion 21 b. The treatment tool X can be inserted into the groove K.

The upper holding portion 21a is formed as an inclined surface in which the width dimension of the upper holding portion 21a gradually decreases from the holding surface 31a to the upper surface 31b, by forming a side end surface S1 on the side from which the front sheet 1a protrudes.

The distance between the upper holding portions 21a, 21a is a distance at which a part of the other upper sheet 1a is covered by the other upper holding portion 21a when the front sheet 1a is inserted into the groove portion K, the bridge portion 2 is disposed in the receiving portion 34, and the leading end of the front sheet 1a is caused to protrude from the one upper holding portion 21 a. In the present embodiment, when the front sheet 1a is set to the above-described state, the entire front sheet 1a is arranged on the lower holding portion 21b and the tip of the front sheet 1a is covered by the upper holding portion 21 a.

One upper holding portion 21a is formed thicker than the other upper holding portion 21 a. In other words, since the one upper holding portion 21a forms the holding surface 31a on the same surface as the other upper holding portion 21a, the height of the one upper holding portion 21a is higher than the height of the other upper holding portion 21 a. Accordingly, the connecting portion 33 becomes thicker from the one upper holding portion 21a side to the other upper holding portion 21a side.

A projection 35 is formed at the distal end of the upper holding portion 21a formed to be thin in the extending direction, and a projection 36 is formed on the lower holding portion 21b so as to face the projection 35. These projections 35 and 36 project from the same positions as the end surface 32c of the lower holding portion 21 b.

The projections 35 and 36 constitute a locking portion 39, and an annular locking member 37 is fitted over the locking portion 39. These protrusions 35, 36 and locking member 37 are means for preventing the upper holding portion 21a from being elastically deformed in the expanding direction when the front sheet 1a is folded.

The locking member 37 is formed with an opening 38 into which the projections 35 and 36 can be inserted properly. The locking member 37 is not necessarily annular as long as it can prevent the space between the upper holding portion 21a and the lower holding portion 21b from increasing, and may be formed in a U shape that can sandwich the protrusions 35 and 36.

The thickness of each of the upper holders 21a, 21a may be 1.9mm or more, but it is preferable to form the upper holders so as to match the size between the front sheet 1a and the rear sheet 1b of the treatment tool X to be set.

The thickness of the coupling portion 33 may be 3.0mm or more, but is preferably 3.4mm or more and 16mm or less.

The groove width of the groove portion K may be set to be equal to or greater than the thickness of the front sheet 1a of the treatment tool X and to be less than or equal to +1mm of the thickness of the front sheet 1 a.

The thickness of the lower holding portion 21b is slightly thicker than the upper holding portion 21a, and specifically, the thickness is in a range of 1mm or more larger than the thickness of the upper holding portion 21a and 2mm or less larger than the thickness of the upper holding portion 21 a.

The molding jig 20C may be made of any material such as a synthetic resin or a metal such as stainless steel as long as it is made of a rigid material.

The upper holding portions 21a and 21a of the molding jig 20C formed as described above are formed at intervals at both ends of the lower holding portion 21b, and the portion other than the one upper holding portion 21a used constitutes an operation portion 30C which grips the molding jig 20C to facilitate the operation of the molding jig 20C.

Next, a method of using the molding jig 20C and its operation will be described.

As shown in fig. 8, when the molding jig 20C is used, the treatment tool X is disposed in the groove portion K such that the front sheet 1a of the treatment tool X faces the lower holding portion 21b and the bridge portion 2 is accommodated in the accommodating portion 34.

When it is desired to fold the space between the holes 3, 3 of the front sheet 1a, the end surface 1c of the treatment tool X is brought close to the side end surface S2 of the upper holder 21a, and the front sheet 1a is projected from the nip 22 so that one hole 3 is visible from the side end surface S1 side. The width of the upper holder 21a is set so that the lower end of the side end surface S1 of the upper holder 21a can be positioned between the holes 3, 3 of the front sheet 1 a. Therefore, in a state where the hole 3 on the base end side of the top sheet 1a is covered by the upper holder 21a, the portion of the top sheet 1a that is further to the top than the portion between the holes 3, 3 protrudes from the side end surface S1 of the upper holder 21 a. In this state, the locking member 37 is fitted over the projection 35 of the upper holding portion 21a and the projection 36 of the lower holding portion 21b, and the treatment tool X is fixed to the molding jig 20C.

Next, the operation portion 30C, which is a portion other than the one upper holding portion 21a from which the front sheet 1a is protruded, is gripped by a hand, the tip end of the protruded front sheet 1a is nipped by a pair of pliers or the like, and the front sheet 1a is bent at a desired angle along the lower end edge of the side end surface S1 of the nip 22.

In addition, at the time of folding, as shown in fig. 10, substantially the entire protruding portion of the front sheet 1a may be further sandwiched by the nip portion 22 of the other molding jig 20C, and the front sheet 1a may be folded between the molding jigs 20C, 20C.

If the front sheet 1a is folded in this manner, the front sheet 1a can be folded so as to match the shape of the thyroid cartilage at a portion where the width between the hole 3 of the front sheet 1a and the hole 3 is sufficient without folding the periphery of the hole 3 on the base end side of the front sheet 1 a. In particular, when the front sheet 1a is folded by two forming jigs 20C as shown in fig. 10, the holes 3 and 3 of the front sheet 1a can be covered with the two forming jigs 20C and folded, respectively, and thus the space between the holes 3 and 3 can be folded more easily.

Therefore, the following effects can be achieved: the front sheet 1a can be prevented from being broken by bending the front sheet 1a on a line passing through the width dimension reduction hole 3 of the front sheet 1 a.

When the leading panel 1a is to be folded at the base end side of the hole 3 on the base end side of the leading panel 1a, the leading panel 1a is inserted into the groove K from the side end face S1, and the bridge portion 2 and the other leading panel 1a are projected from the side end face S1. Then, the base end portion of the top sheet 1a is folded by grasping the vicinity of the bridge portion 2.

By using the molding jig 20C in this manner, the front sheet 1a can be bent near the base end of the front sheet 1a and at a position avoiding the hole 3.

The molding jig 20C is configured to be able to hold the operation unit 30C accommodating substantially the entire treatment tool X and to protrude only the distal end of the front sheet 1a to be bent. Therefore, the forming jig 20C can achieve an effect of easily and stably folding the front sheet 1 a.

Further, since the molding jig 20C can fix the protrusions 35 and 36 by the locking member 37, the upper holding portion 21a and the lower holding portion 21b can be prevented from being deformed at the time of bending.

The locking member 37 described in the present embodiment is not essential as long as the clip 22 can be securely fixed while being sandwiched therebetween, or the clip 22 has rigidity to such an extent that it is difficult to deform.

Further, when the molding jig 20C is made of a material having high rigidity such as stainless steel, it can be formed to be thin and small as shown in fig. 11.

As shown in fig. 11 and 12, the left and right upper holding portions 21a and 21a of the molding jig 20C may be formed to have the same thickness.

When the front sheet 1a to be folded is provided between the upper holding portions 21a, 21a of the forming jig 20C in one upper holding portion 21a, a different front sheet 1a may not be covered by the other upper holding portion 21 a.

The side end surface S2 may have an inclined surface whose dimension in the width direction increases toward the holding surface 31 a.

As shown in fig. 11, the upper holding portion 21a of the molding jig 20C may have a different width dimension in the longitudinal direction. By forming the upper holding portion 21a in this manner, the following effects can be achieved: the same molding jig 20C can process the front sheet 1a having a position of the hole 3 from the base end or a position different between the holes 3 and 3.

Further, the inner side 70 of the corner formed by the coupling portion 33 and the upper holding portion 21a (i.e., the inner wall side of the intersection of the upper holding portion 21a and the coupling portion 33) and the corner 70 in which the width dimension of the upper holding portion 21a is changed may be cut out in a cylindrical shape. Even if it is intended to form corners in the molding process of the molding jig 20C such that planes completely intersect each other at a desired angle, the thick wall of the molding jig 20C remains in a very small portion of the corner. In this case, the end of the treatment tool X cannot contact the side surface 34a of the accommodation portion 34 that blocks the treatment tool X, and the treatment tool X may shake. Therefore, by forming the corner portion 70 as the cylindrical cutout portion 70, it is possible to avoid forming a corner portion in which a thickness remains at a portion where planes intersect with each other, and it is possible to sufficiently contact the treatment tool X to the side surface 34 a. Since the surface 34b facing the distal end direction of the upper holding portion 21a is a surface that blocks a part of the treatment tool X, the same applies to the corner portion 70 that changes the width dimension of the upper holding portion 21 a.

Further, a stripe-shaped groove 71 may be formed on the surface of the lower holding portion 21b along the side end surface S2. By forming such a groove 71, the friction surface between the treatment tool X and the lower holding portion 21b is reduced, and thus, it is possible to prevent the treatment tool X from being scratched with a fine scratch or the like.

As shown in fig. 11 and 12, when the front sheet 1a is to be folded toward the base end side of the hole 3 on the base end side of the front sheet 1a, the front sheet 1a may be sandwiched from both sides by 2 molding jigs 20C, and the molding jigs 20C, 20C may be folded toward each other. This bending method can be similarly applied to the molding jig 20C shown in fig. 8.

As shown in fig. 13, the anti-slip portion 50 formed of corrugated irregularities may be formed concentrically on the back surface of the lower holding portion 21 b. At this time, it is preferable that the slip prevention portions 50 having a plurality of concentric uneven portions are formed in a row at positions where the finger pulp almost touches when the molding jig 21C is gripped. If the non-slip portion 50 is formed in this way, an effect of enabling the position suitable for grasping the molding jig 20C to be grasped with a tactile sensation can be achieved. The shape of the antiskid portion 50 is not limited to the shape shown in fig. 13.

Next, a molding jig 20D according to a fourth embodiment of the present invention will be described with reference to fig. 14 to 16.

Since the molding jig 20D of the present embodiment is a modification of the molding jig 20A of the first embodiment, the same points as those of the molding jig 20A of the first embodiment will not be described, and the differences will be mainly described.

As shown in fig. 14, the molding jig 20D includes a pair of clamp halves 51 and 52 fixed to a shaft 53 to be rotatable.

The clamp half body 51 has: a lower holding portion 21b formed on the distal end side of the insertion portion 53a of the shaft portion 53; and a handle 54 formed on the opposite side of the lower holding portion 21b from the insertion portion 53 a.

The clamp half 52 has: an upper holding portion 21a formed on the distal end side of the insertion portion 53a of the shaft portion 53; and a handle 54 formed on the opposite side of the upper holding portion 21a from the insertion portion 53 a.

The clamp halves 51 and 52 are assembled so that the shaft portions 53 are fitted to the insertion portions 53a and intersect each other with the shaft portions 53 as intersection points, and have a structure called forceps.

The upper holding portion 21a and the lower holding portion 21b are paired, and have holding surfaces 31a and 32a capable of sandwiching and fixing the front sheet 1 a. The holding surfaces 31a and 32a are formed at the distal ends of the upper holding portion 21a and the lower holding portion 21b, each having a flat surface and being in close contact with each other.

The upper holding portion 21a has an inclined surface (also referred to as an outer surface) 55, and the inclined surface 55 extends in a V shape toward the shaft portion 53 as a base end at a predetermined angle with respect to the holding surface 31 a. The angle formed by the holding surface 31a and the inclined surface 55 is not necessarily limited, but is set to 10 degrees or more and 30 degrees or less, and preferably 15 degrees or more and 25 degrees or less.

The lower holding portion 21b is cut out on the base end side of the holding surface 32a to form a space 65. The outer surface 58 of the lower holding portion 21b is formed in a substantially L shape.

The width (the dimension on the vertical paper in fig. 14) of the upper holding portion 21a and the lower holding portion 21b is set to be equal to or larger than the width of the front sheet 1 a.

The one holding surface 32a is formed with a protrusion 56 that fits into the hole 3 of the front sheet 1a, and the other holding surface 31a is formed with a recess, not shown, that receives the protrusion 56. The holding surfaces 31a, 32a are formed so as to cover at least the entire hole 3 when the protrusion 56 is passed through the hole 3.

A pressing member 60 for bending the front sheet 1a protruding from the distal end of the upper holding portion 21a in the vicinity of the distal end of the upper holding portion 21a is fixed to the inclined surface 55.

The pressing member 60 includes a handle portion 61, a shaft portion 62, and a pressing portion 63.

The handle portion 61 is formed in a linear bar shape.

The pressing portion 63 extends in a direction away from the inclined surface 55 with the shaft portion 62 as a starting point, and is bent into a substantially L-shape. The pressing portion 63 approaches the inclined surface 55 of the upper holding portion 21a in conjunction with the lifting of the handle portion 61, and presses and bends the front sheet 1a protruding from the distal end of the upper holding portion 21 a.

In the above configuration, as shown in fig. 14, when the leading sheet 1a is to be bent toward the proximal end side of the hole 3 on the proximal end side, the projection 56 is inserted through the hole 3 on the proximal end side of the leading sheet 1a and sandwiched between the upper holding portion 21a and the lower holding portion 21b, and the bridge portion 2 is projected from the distal ends of the upper holding portion 21a and the lower holding portion 21 b. At this time, the molding jig 20D is set such that the hole 3 on the base end side is covered with the holding surfaces 31a and 32a, and the distal edge of the holding surface 31a is positioned away from the hole 3. Further, since the tip of the rear sheet 1b of the front sheet 1a placed on the holding surface 32a is positioned to substantially contact the outer surface 58 of the lower holding portion 21b, the treatment tool X can be easily set.

When the top sheet 1a is sandwiched between the upper holding portion 21a and the lower holding portion 21b, the handle 61 is pressed down, and the portion closer to the base end side than the hole 3 is pressed by the pressing portion 63, thereby folding the top sheet 1 a.

When it is desired to fold the space between the holes 3, 3 of the top sheet 1a, the projections 56 may be inserted into the holes 3 on the top end side of the top sheet 1a, and the bridge portions 2 may be projected from the top ends of the upper holding portion 21a and the lower holding portion 21b, as shown in fig. 14. Even in this case, the hole 3 can be reliably covered, the leading edge of the holding surface 32a is positioned between the holes 3 and 3, and the front sheet 1a can be folded in the vicinity of the leading edge.

However, when the top end portion of the front sheet 1a is sandwiched only by the upper holding portion 21a and the lower holding portion 21b, the treatment tool X may be difficult to set due to a poor balance, and therefore, it is preferable to set the treatment tool X between the holes 3 and 3 as shown in fig. 15.

That is, the projection 56 is inserted into the hole 3 on the proximal end side of the front sheet 1a to be folded, and the bridge portion 2 and the other front sheet 1a are accommodated in the space 65. In this way, the leading edge of the holding surface 32a is positioned between the holes 3 and 3 of the front sheet 1a, and can be folded at a portion. Further, if the treatment instrument X is provided in this way, the distal end of the rear surface piece 1b approaches the inner surface where the lower holding portion 21b is cut out, and the treatment instrument X can be prevented from being largely inclined toward the bridge portion 2 side, so that the treatment instrument X can be easily provided. Further, the distal end of the front sheet 1a different from the front sheet 1a to be bent can be supported by the inner surface of the lower holding portion 21b, and therefore, the stability when the treatment tool X is set is improved.

According to the above structure, the molding jig 20D can achieve the following effects: the front sheet 1a can be easily and reliably held in a state where the holes 3 and the periphery thereof at the portions where bending is not desired are covered, and the front sheet 1a can be easily folded by the pressing member 60 at the portions where the holes 3 do not pass.

In addition, according to the structure of the molding jig 20D, the following effects can be achieved: when the space between the holes 3, 3 is folded, the tip of the front sheet 1a can be projected from the upper holding portion 21a and the lower holding portion 21b, and the remaining portions can be stably and reliably held on the holding surfaces 31a, 32a and the space 65.

As shown in fig. 16, the molding jig 20D may have the following structure: the lower holding portion 21b is not formed with a cutout portion for forming the space 65, and the holding surfaces 31a and 32a can be brought into close contact with each other.

Even with such a structure, the molding jig 20D can achieve the following effects: the holes 3 of the front sheet 1a can be reliably covered by the upper holding portion 21a and the lower holding portion 21b, and the front sheet 1a protruding from the top ends of the upper holding portion 21a and the lower holding portion 21b can be bent in the vicinity of the top ends.

The embodiments of the present invention have been described above by way of example, but the present invention is not limited to the contents of the above embodiments, and can be applied by appropriately combining the configurations of the embodiments. For example, in the molding jig 20B of the second embodiment, the locking member 37 as shown in the third embodiment may be used to prevent the spread of the clip portion 22.

In each embodiment, the method of using only one forming jig 20A to 20C and using another jig such as a pair of pliers for the tip end portion of the front sheet 1a protruding from the nip 22 has been described, but the tip end portion of the front sheet 1a protruding from the nip 22 may be held by any of the other forming jigs 20A to 20C to fold the front sheet 1 a. By holding the tip end portion protruding from the clip portion 22 also with any one of the molding jigs 20A to 20C in this way, the following effects can be achieved: the front sheet 1a can be more easily bent and prevented from being bent on a line passing through the hole 3 formed in the distal end portion.
