Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Referring to fig. 1-7, the endoscopic grasper of the present invention, in one embodiment, includes an applicator cap 1, a stationary handle 2, a sliding handle 3, and an outer sheath 4. Wherein, applying cap 1 includes base 11 and grabbing portion 12, and base 11 can set up on endoscope (not shown in the figure) to cooperate the endoscope to accomplish through grabbing portion 12 (the mode of grabbing will be described in detail below) and snatch, thereby, avoided the invasion of other grabbing tools, also reduced patient's discomfort.

The gripping part 12 is pivotally connected to the base 11, and the gripping part 12 is connected to the sliding handle 3 through the outer sheath tube 4, and the fixed handle 2 is sleeved on the sliding handle 3, so that when the sliding handle 3 slides along the fixed handle 2 by applying force, the outer sheath tube 4 can apply force to the gripping part 12 to actuate the gripping part 12, so that the gripping part 12 can pivot relative to the base 11. Thus, the grasping portion 12 can pivot relative to the base 11 to open (see also fig. 2) and close (see also fig. 3) to grasp foreign matter within the digestive tract when open and grasp foreign matter for removal along the digestive tract when closed. Since the opening and closing force of the grasping portion 12 can be controlled by sliding the handle 3 and the outer sheath tube 4, the grasping portion 12 can grasp foreign objects of different sizes flexibly.

Further, a stop (not shown) may be provided in the fixed handle 2 and a stop groove (not shown) may be provided in the sliding handle 3, so that when the sliding handle 3 is slid into place, the stop will lock in the stop groove to stop and complete the closing of the gripping portion 12. Of course, it is also possible to provide the stop in the sliding handle 3 and the stop groove in the fixed handle 2. Preferably, the grasping portion 12 can be made of a transparent material, so that the endoscope can acquire images in the alimentary canal through the grasping portion 12, the endoscope is not affected by shielding, and the visual field range is wider.

Furthermore, the base 11 is provided with closely arranged small holes 17 along the circumference, wherein the small holes 17 can be arranged at the front end of the base 11, but of course, can be arranged at other positions. In actual medical operations, some medical institutions may clean and reuse the application cap 1 in order to save costs. However, according to the application cap 1 of the present invention, substances such as tissue fluid may remain on the walls of the closely arranged pores 17 during medical treatment, and since the pores 17 are small in size and thin, it is difficult to clean the walls, and therefore the application cap 1 used in the medical institution has to be discarded. Thus, the application cap 1 of the present invention can effectively prevent secondary utilization to reduce cross-infection and bacterial growth between different patients.

According to the grabber used under the endoscope, the base 11 of the applying cap 1 can be sleeved on the endoscope to be matched with the endoscope to complete grabbing, so that invasion of other grabbing tools is avoided, and discomfort of a patient is reduced; meanwhile, the sliding handle 3 pivots the grabbing part 12 relative to the base 1 through the sheath tube 4, so that the foreign bodies in the alimentary canal can be grabbed flexibly, and the device is suitable for grabbing foreign bodies with different sizes. Meanwhile, the small holes which are arranged closely on the base can effectively prevent the secondary utilization of the application cap.

Referring to fig. 2 to 3, in the grasping apparatus for an endoscope of the present invention, in one embodiment, the grasping portion 12 includes a first grasping portion 13 and a second grasping portion 14, and the first grasping portion 13 and the second grasping portion 14 may be oppositely disposed at the front end of the base 11. Further, the first and second grasping portions 13 and 14 are respectively provided along a half circumference of the front end of the base 11 and extend forward in an elliptical shape, thereby forming a "spoon". Thus, as shown in fig. 2, first and second grasping portions 13 and 14 in the shape of a "spoon" can grasp and hold larger foreign matters by the concave spoon portion in the opened state; as shown in fig. 3, first gripping portion 13 and second gripping portion 14 may grip or contain the foreign matter in a closed "scoop" in a closed state, so that the foreign matter is not allowed to slip off when removed from the alimentary tract.

Referring to fig. 8 in combination, in the grasper for use under an endoscope of the present invention, in one embodiment, the outer sheath tube 4 may include a first outer sheath tube 41 and a second outer sheath tube 42, and the slide handle 3 may include a first slide handle 31 and a second slide handle 32. Wherein the first grasping portion 13 is connected to the first slide handle 31 through a first sheath 41, and the second grasping portion 14 is connected to the second slide handle 32 through a second sheath 42. Also, one fixed handle 2 may be put on the first slide handle 31 and the second slide handle 32, or two different fixed handles 2 may be put on the first slide handle 31 and the second slide handle 32, respectively. Thus, the first slide handle 31 and the second slide handle 32 can slide along the fixed handle 2, respectively, to actuate the first grasping portion 13 and the second grasping portion 14 to pivot relative to the base 11, respectively. In this way, the pivoting of the first and second gripping parts 13 and 14, respectively, can be manipulated in conjunction with different pieces of foreign matter to apply different forces to accomplish the gripping and removal of foreign matter of different sizes.

Referring to fig. 4 to 5, in the grasping apparatus for an endoscope of the present invention, in one embodiment, the grasping portion 12 includes a first grasping portion 13 and a second grasping portion 14, and the first grasping portion 13 and the second grasping portion 14 may be oppositely disposed at the front end of the base 11. Further, the first grasping portion 13 and the second grasping portion 14 are respectively disposed along a radius of the front end of the base 11 and extend forward in a plane, thereby forming "forceps". Thus, the first and second grasping portions 13 and 14 in the shape of "forceps" are more easily urged to grasp foreign matter. Meanwhile, the first grabbing part 13 and the second grabbing part 14 are arranged along the radius of the front end of the base 11, and a half space can be reserved at the front end of the base 11, so that the lens of the endoscope is avoided. As shown in fig. 4, in the open state, the first grasping portion 13 and the second grasping portion 14 in the shape of "pliers" can grasp larger foreign objects by applying larger force through the "pliers" plane; and as shown in fig. 5, the first and second grasping portions 13 and 14 can clamp the foreign matter in the closed state.

Further, as shown in fig. 4, the first and second grasping portions 13 and 14 are provided with raised stripes 15 on opposite sides thereof. In this way, raised stripe 15 can play the effect of increasing friction to avoid the foreign matter to slide off from between first portion 13 and the second portion 14 of grabbing, increased the clamping force.

Referring to fig. 8 in combination, in the grasper for use under an endoscope of the present invention, in one embodiment, the outer sheath tube 4 may include a first outer sheath tube 41 and a second outer sheath tube 42, and the slide handle 3 may include a first slide handle 31 and a second slide handle 32. Wherein the first grasping portion 13 is connected to the first slide handle 31 through a first sheath 41, and the second grasping portion 14 is connected to the second slide handle 32 through a second sheath 42. Also, one fixed handle 2 may be put on the first slide handle 31 and the second slide handle 32, or two different fixed handles 2 may be put on the first slide handle 31 and the second slide handle 32, respectively. Thus, the first slide handle 31 and the second slide handle 32 can slide along the fixed handle 2, respectively, to actuate the first grasping portion 13 and the second grasping portion 14 to pivot relative to the base 11, respectively. In this way, the pivoting of the first and second gripping parts 13 and 14, respectively, can be manipulated in conjunction with different pieces of foreign matter to apply different forces to accomplish the gripping and removal of foreign matter of different sizes.

Referring to fig. 6-7, the endoscopic grasper of the present invention, in one embodiment, the applicator cap 1 further includes a fixed portion 16 fixedly disposed on the base 11, wherein the fixed portion 16 and the graspable portion 12 are oppositely disposed at the front end of the base 11. Further, the fixing portion 16 and the grasping portion 12 are respectively disposed along a half circumference of the base 11 and extend in a forward elliptical shape, so that the grasping portion 12 forms a "spoon" and can be engaged with the fixing portion 16 when closed. Thus, as shown in fig. 6, the grasping portion 12 in the shape of a "spoon" can grasp and hold larger foreign matters by the concave spoon portion in the opened state; and as shown in fig. 7, gripping portion 12 may cooperate with holding portion 16 to grip or contain a foreign object within the closed "scoop" in the closed position. The provision of a single fixing portion 16 and a single gripping portion 12 in this embodiment provides greater gripping and holding power by the fixing portion 16 than the provision of two movable gripping portions in the embodiment shown in figures 2-3 to allow for the gripping of heavier items.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
