Technical Field

The invention relates to a medical apparatus, in particular to a gasbag type obstetric forceps.

Background

An obstetric forceps is an instrument which can be used for assisting a parturient in delivering a baby. Obstetric forceps midwifery is a commonly used operation for solving dystocia in obstetrics, and the obstetric forceps can obviously shorten the labor process so as to ensure that a fetus is smoothly born. Obstetric forceps midwifery usually requires doctors to have rich experience, and the holding position of the obstetric forceps needs to be well mastered, especially the holding force needs to be well controlled. If the clamping force is too large, the head of the fetus is easily damaged by pressure, and if the clamping force is too small, the obstetric forceps are easy to slip.

In most cases, in order to prevent the head of the fetus from slipping, a midwife usually unconsciously increases the clamping force when pulling the forceps handle outwards, thereby causing the head of the fetus to be damaged. In addition, the head shapes of the fetuses are different, so that the forceps leaves of the obstetric forceps cannot be well attached to the head of each fetus, the contact area between the forceps leaves and the head of the fetus is small, the head of the fetus is easy to slip, or the head of the fetus is damaged due to over-pressure.

Disclosure of Invention

The invention provides an air bag type obstetric forceps which can keep stable clamping force in the using process, and an air bag can be extruded through an air bag hole to form uniformly distributed air bag protruding parts so that the head of a fetus is contacted with the air bag protruding parts.

In order to achieve the above purpose, the technical scheme of the invention is as follows:

a balloon type forceps comprising: the pair of clamp bodies are symmetrically arranged and can approach or depart from each other. Each of the pair of caliper bodies includes: a forceps handle; the clamp blade is fixedly connected with the clamp handle, a cavity is formed in the clamp blade, and an opening is formed in one end, connected with the clamp handle, of the clamp blade; the adjusting blade is arranged in the cavity, one end of the adjusting blade extends out of the cavity through the opening, and an accommodating cavity is formed between the adjusting blade and the side wall of the clamp blade close to the other clamp body; and the air bag is arranged in the accommodating cavity. The side wall is uniformly distributed with air bag holes, one end of the adjusting blade extending out of the cavity is connected with the clamp handle in a sliding mode, so that the adjusting blade can move towards the other clamp body and compress the air bag when moving, and the air bag is extruded out through the air bag holes.

Preferably, the balloon type forceps further comprise: one end of the first screw rod is fixedly connected with one of the two forceps handles; the other forceps handle of the two forceps handles is provided with a first through hole for the first screw rod to pass through; and the first fixing piece is arranged at the other end of the first screw rod and comprises a first nut and a second nut which are matched with the first screw rod and positioned at two sides of the other clamp handle.

Preferably, one end of the one forceps handle, which is far away from the forceps blade connected with the one forceps handle, is connected with a sleeve, and one end of the other forceps handle, which is far away from the forceps blade connected with the other forceps handle, is connected with a slide rod in sliding fit with the sleeve.

Preferably, the forceps body further comprises: one end of the second screw rod is fixedly connected with one end of the adjusting blade, which extends out of the cavity, and the forceps handle is provided with a second through hole for the second screw rod to pass through; and the second fixing piece is arranged at the other end of the second screw rod and comprises a third nut which is matched with the second screw rod and is positioned on one side of the clamp handle, which is far away from the adjusting blade.

Preferably, the opening is provided with a first arc-shaped elastic sheet, one end of the first arc-shaped elastic sheet is fixedly connected with the side wall, and the other end of the first arc-shaped elastic sheet is located between the adjusting blade and the air bag.

Preferably, a second arc-shaped elastic sheet is fixed on the inner wall of the accommodating cavity far away from the opening, and one end of the second arc-shaped elastic sheet far away from the inner wall is located between the adjusting blade and the air bag.

Preferably, the outer surface of the air bag is provided with anti-skid lines.

The invention has the beneficial effects that:

1. when the air bag type obstetric forceps are used, the distance between the two forceps leaves can be kept unchanged through the first screw rod and the first fixing piece, so that stable clamping force can be kept, and even if a midwife unconsciously increases the clamping force, the head of a fetus cannot be damaged;

2. the air bag can be extruded through the air bag holes to form the uniformly distributed air bag protruding parts, so that the head of the fetus is in contact with the air bag protruding parts, and therefore when the clamping force is adjusted, the buffer effect of the air bag protruding parts is utilized, the phenomenon that the head of the fetus is clamped too tightly due to sudden force application of a midwife due to tension is avoided, and the midwife safety is improved;

3. the air bag protruding part can automatically adjust the volume of the air bag protruding part according to the shape of the fetal head, namely, the volume of the air bag protruding part is smaller at the position where the fetal head protrudes, and the volume of the air bag protruding part is larger at the position where the fetal head is sunken, so that the air bag protruding part can be self-adapted to the shape of the fetal head, and the contact area between the air bag protruding part and the fetal heads with different shapes is ensured, thereby being beneficial to smooth delivery assistance.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

In some embodiments, as shown in fig. 1, the balloon type forceps of the present invention includes a pair of forceps bodies 10 which are symmetrically disposed, and the pair of forceps bodies 10 can be moved toward or away from each other. Each of the pair of forceps bodies 10 includes a forceps handle 11, a forceps blade 12, an adjusting blade 13, and an air bag 14. The forceps leaves 12 are fixedly connected with the forceps handles 11.

In some examples, the balloon type forceps further include a first screw 15 and a first fastener 16. One end of the first screw 15 is fixedly connected with one of the two forceps handles 11, and the other forceps handle 11 of the two forceps handles 11 is provided with a first through hole for the first screw 15 to pass through. The first fixing member 16 is disposed at the other end of the first screw 15, and includes a first nut 161 and a second nut 162 engaged with the first screw 15 and located at both sides of the other forceps handle 11. By arranging the first screw 15 and the first nut 161 and the second nut 162, the distance between the pair of caliper bodies 10 can be kept constant after the pair of caliper bodies are moved closer to or away from each other.

In some examples, a sleeve 111 is connected to an end of one of the handles 11 remote from the connected blade 12, and a slide rod 112 slidably engaged with the sleeve 111 is connected to an end of the other handle 11 remote from the connected blade 12. The first screw 15 and the sliding sleeve 111 and the sliding rod 112 are used to prevent the two clamp leaves 12 from rotating relatively during the process of moving the pair of clamp bodies 10 toward or away from each other, which would result in ineffective clamping.

In one forceps body 10, a cavity 121 is formed inside the forceps blade 12, and an opening 122 is formed at one end of the forceps blade 12 connected to the forceps handle 11. The adjusting blade 13 is installed in the cavity 121, and one end of the adjusting blade 13 extends out of the cavity 121 through the opening 122, and a receiving cavity 123 is formed between the adjusting blade 13 and the side wall of the caliper blade 12 close to the other caliper body 10. The air bag 14 is disposed in the accommodation chamber 123. Wherein, the side wall is evenly distributed with air bag holes 124. One end of the adjusting blade 13 protruding out of the cavity 121 is slidably connected to the caliper handle 11 so that the adjusting blade 13 can move toward the other caliper body 10 and compress the air bag 14 when moving to extrude the air bag 14 through the air bag hole 124. The bladder 14 is extruded through the uniformly distributed bladder apertures 124 so that uniformly distributed bladder protrusions 141 can be formed, which bladder protrusions 141 contact the fetal head during use. Illustratively, the outer surface of the air bag 14 is provided with anti-slip lines, which is beneficial to increase the friction force between the air bag protrusion 141 and the fetal head, and avoid the fetal head from slipping.

In some examples, the forceps body 10 further includes a second threaded rod 17 and a second fastener 18. One end of the second screw 17 is fixedly connected with one end of the adjusting blade 13 extending out of the cavity 121, and the forceps handle 11 is provided with a second through hole for the second screw 17 to pass through. The second fixing member 18 is disposed at the other end of the second screw 17, and includes a third nut 181 engaged with the second screw 17 and located on the side of the caliper handle 11 away from the adjustment blade 13. When the adjusting blade 13 is urged to move toward the other caliper body 10 in this way, the second screw is moved synchronously, and then the adjusting blade 13 can be fixed by rotating the third nut 181. At this time, the airbag 14 is in a compressed state and is extruded through the airbag holes 124, forming uniformly distributed airbag protrusions 141.

In some examples, the opening 122 is provided with a first arc-shaped elastic sheet 19, one end of the first arc-shaped elastic sheet 19 is fixedly connected with the side wall, and the other end is located between the adjusting blade 13 and the air bag 14. By providing the first arc-shaped elastic sheet 19, the airbag 14 is not extruded through the opening 122 in the process of pressing the airbag 14, so that the airbag 14 can be ensured to smoothly form the airbag protrusion 141.

In some examples, a second arc-shaped spring piece 20 is fixed on an inner wall of the accommodating cavity 123 far away from the opening 122, and one end of the second arc-shaped spring piece 20 far away from the inner wall is located between the adjusting blade 13 and the air bag 14. By providing the second arc-shaped elastic piece 20, the air bag 14 is not extruded through the gap between the adjusting blade 13 and the inner wall of the accommodating cavity 123 in the process of pressing the air bag 14, thereby ensuring that the air bag 14 can smoothly form the air bag protrusion 141.

When the fetal heart rate measuring forceps are used, the first nut 161 and/or the second nut 162 are/is firstly rotated to enable the first nut and the second nut to be separated by a certain distance, and then the distance between the two forceps bodies 10 is adjusted to enable a space to be reserved for the fetal head. Next, the two forceps 12 of the air-bag type forceps are placed on both sides of the fetal head, and the distance between the two forceps bodies 10 is adjusted so that the two forceps 12 are in contact with the fetal head, and at this time, the air bag 14 is completely located in the accommodating cavity 123. Then, the first nut 161 and/or the second nut 162 are/is adjusted to keep the two caliper bodies 10 relatively fixed, thereby completing the initial adjustment of the clamping force. Subsequently, the two adjustment blades 13 are adjusted to slide relative to the corresponding forceps handles 11, so that the two air bags 14 are pressed to form the air bag protrusions 141, and the third nut 181 is rotated to fix the air bags, thereby completing fine adjustment of the clamping force. Finally, the sleeve 111 is held by hand to apply force to assist delivery.

It should be noted that fine adjustment can be performed several times according to the actual condition of the fetus delivery, so that the clamping force is gradually increased to improve the safety of the delivery.

Although the present invention has been described above with reference to the embodiments and the accompanying drawings, the present invention is not limited thereto, but various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present invention. The scope of the invention is to be determined by the appended claims, and all technical ideas within the scope equivalent to the claims are included in the scope of the invention.
