[0039] Figure 1 is a schematic structural diagram of a handle 100 in an initial state according to some embodiments of the present application. Figure 2 Schematic diagram of the structure of the handle 100 in the initial state of some other embodiments of the present application, Figure 3 This is a schematic diagram of the partial structure of the handle 100 in a working state in some embodiments of the present application, in which the X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction. The first direction X, the second direction Y and the third direction Z intersect each other.

[0040] like Figures 1 to 3 As shown, the embodiment of the present application provides a handle 100 for a medical opening and closing device 10, the handle 100 includes: a main rod 110, including a support body 111 and a support member 112 located at one end of the support body 111 in a first direction X, the support member 112 is provided with a slide groove 112a extending along the first direction X on a side away from the support body 111, and the slide groove 112a has an opening 112b on a side away from the support body 111; an auxiliary rod 120, including an elastic body 121 and a head 122 located at one end of the elastic body 121 in the first direction X, the end of the elastic body 121 away from the head 122 is connected to the support body 111, and the head 122 is protruding from the elastic body 121 in the second direction Y, wherein the handle 100 has a working state, in which the head 122 is located in the slide groove 112a, and a part of the elastic body 121 is spaced apart from the support body 111, so that the head 122 moves in the slide groove 112a through the deformation of the elastic body 121.

[0041] Figure 4 This is a schematic diagram of the structure of a medical opening and closing device 10 according to some embodiments of the present application. Figure 5 Schematic cross-sectional view of a medical opening and closing device 10 according to some embodiments of the present application. Figure 6 for Figure 5 A local enlarged schematic diagram of point A in the middle.

[0042] like Figures 3 to 6As shown, a handle 100 for a medical opening and closing device 10 provided in an embodiment of the present application includes a main rod 110 and an auxiliary rod 120. The main rod 110 includes a support body 111 and a support member 112 located at one end of the support body 111 in a first direction X. Optionally, the main rod 110 also includes a first connecting portion 113 disposed at one end of the support body 111 facing the support member 112, and the first connecting portion 113 can be used to connect to the housing 200 of the medical opening and closing device 10.

[0043] In some embodiments of the present application, there are multiple ways to connect the first connection portion 113 to the housing 200 of the medical opening and closing device 10. Among them, the first connection portion 113 can be detachably connected to the housing 200 of the medical opening and closing device 10, so as to facilitate the replacement of the handle 100 of the medical opening and closing device 10, so that after the medical opening and closing device 10 is used once, the handle 100 does not need to be sterilized and can be directly replaced.

[0044] Optionally, the first connection portion 113 can be connected to the housing 200 of the medical opening and closing device 10 by snapping, threading or bolting, which is not specifically limited in the present application. For ease of description, the following embodiments are illustrated by taking the first connection portion 113 as a buckle, and the first connection portion 113 can be connected to the housing 200 of the medical opening and closing device 10 by snapping, so as to facilitate the removal and installation of the handle 100.

[0045] like Figure 2 As shown, optionally, the handle 100 may also have an initial state, in which the head 122 and the support member 112 may be spaced apart, that is, the head 122 may not be located in the slide groove 112a. By arranging a portion of the elastic body 121 and the support body 111 to be spaced apart, the handle 100 may be transformed between the initial state and the working state through the deformation of the elastic body 121.

[0046] The support member 112 is provided with a slide groove 112a extending along the first direction X on one side away from the support body 111, and the slide groove 112a has an opening 112b on the side away from the support body 111. The auxiliary rod 120 includes an elastic body 121 and a head 122 located at one end of the elastic body 121 in the first direction X, and the head 122 is protruding from the elastic body 121 in the second direction Y, wherein, by setting the end of the elastic body 121 away from the head 122 to be connected to the support body 111, and part of the elastic body 121 is spaced apart from the support body 111, so that when the head 122 of the handle 100 is not located in the slide groove 112a, for example, when the handle 100 is in the initial state, the head 122 of the handle 100 and the support member 110 are not located in the slide groove 112a. When the interval setting of 112 makes the handle 100 have a larger volume, the operator can press the elastic body 121 to deform the elastic body 121 so that the elastic body 121 can be close to the support body 111, so that the head 122 at one end of the elastic body 121 can gradually approach the support member 112, and the head 122 can move in the first direction X, so that the head 122 can enter the slide groove 112a through the opening 112b of the slide groove 112a, so that the head 122 can move in the slide groove 112a, so that the handle 100 can be converted from the initial state to the working state with a smaller volume, which can facilitate the support member 112 and the head 122 of the handle 100 to enter the shell 200 of the medical opening and closing device 10.

[0047] Furthermore, when the support member 112 and the head 122 of the handle 100 enter the housing 200 of the medical opening and closing device 10, the operator can press the elastic body 121 to deform the elastic body 121, so that the head 122 can move away from the support frame in the first direction X in the slide groove 112a, so that the head 122 can drive the working part 420 of the medical opening and closing device 10 to approach each other, so as to achieve the clamping or shearing work of the medical opening and closing device 10. Therefore, the handle 100 provided in the present application can drive the clamping or shearing work of the medical opening and closing device 10 only by the deformation of the elastic body 121, so that the handle 100 can have a relatively simple structure, which can facilitate the production and manufacture of the handle 100.

[0048] like Figures 4 to 6As shown, in some optional embodiments, the medical opening and closing device 10 may include a shell 200, a kit 300, an inner core 400 and a handle 100 provided in any embodiment of the present application. The shell 200 may include a wall portion 210 and a accommodating space 220 formed by the wall portion 210. The wall portion 210 is provided with a mounting hole 230 and a working hole 240 which are connected to the accommodating space 220 and are opposite to each other in the first direction X. The first connecting portion 113 of the handle 100 can be connected to the mounting hole 230. For example, the first connecting portion 113 can be snap-fitted with the mounting hole 230. The head 122 of the handle 100 and the support member 112 are arranged in the accommodating space 220.

[0049] Part of the kit 300 is arranged in the accommodating space 220 and is located on the side of the head 122 away from the supporting body 111, and the kit 300 is movably arranged relative to the shell 200 in the first direction X, so that when the operator presses the elastic body 121 to make the head 122 move along the first direction X toward the kit 300, the head 122 can better contact with the kit 300 to push the kit 300 to move along the first direction X toward the side away from the handle 100. The kit 300 has a working space 300a extending along a first direction X. One end of the inner core 400 is used to be exposed from the working space 300a, and the other end extends through the working space 300a to the accommodating space 220, and is fixedly connected to the shell 200 in the accommodating space 220. When the handle 100 is in a working state, the operator can press the elastic body 121 to move the head 122 in the slide groove 112a along the first direction X, so that the head 122 can push the kit 300 to move away from the handle 100 along the first direction X, so that the inner core 400 can be retracted into the working space 300a, so that the kit 300 can squeeze the working part 420 of the inner core 400, so that adjacent working parts 420 can approach each other, so as to drive the working parts 440 of adjacent inner cores 400 to approach each other, thereby realizing the driving of the handle 100 to clamp or shear the medical opening and closing device 10.

[0050] Optionally, when the handle 100 is not connected to the shell 200 and the handle 100 is in a working state, that is, the head 122 of the handle 100 is located in the slide groove 112a of the support member 112, the operator can press the elastic body 121 to deform the elastic body 121 so that the head 122 can move away from the support frame in the slide groove 112a along the first direction X. When the head 122 moves to slide out of the slide groove 112a from the opening 112b of the slide groove 112a, the head 122 at one end of the elastic body 121 can be free from the restriction of the slide groove 112a and move away from the support member 112, so that the handle 100 can be switched from the working state to the initial state.

[0051] Therefore, in the handle 100 provided in the embodiment of the present application, the operator can deform the elastic body 121 only by pressing the elastic body 121, so that the head 122 of the auxiliary rod 120 can move in the first direction X, so that the head 122 of the auxiliary rod 120 can slide into the slide groove 112a through the opening 112b, or the head 122 of the auxiliary rod 120 can slide out of the slide groove 112a through the opening 112b, that is, the operator can switch the head 122 and the support member 112 between a separated state (i.e., an initial state) and a mating state (i.e., a working state) only by pressing the elastic body 121 to deform the elastic body 121. Therefore, optionally, the auxiliary rod 120 does not need to be separately provided from the main rod 110. Specifically, the auxiliary rod 120 can be formed integrally with the main rod 110, and the head 122 and the support member 112 can be switched from a separate state to a matching state with a smaller volume by only pressing the elastic body 121 to deform the elastic body 121, so as to facilitate the connection of the housing 200 of the medical opening and closing device 10, and to facilitate the production and manufacture of the handle 100. Optionally, the handle 100 can be made by an injection molding process, so as to facilitate the production and manufacture of the handle 100, and compared with metal materials, the handle 100 made by the injection molding process can also have a lower cost.

[0052] Optionally, the material of the auxiliary rod 120 may include elastic material, so that the elastic body 121 can have good elasticity, so that the elastic body 121 can produce good deformation when pressed by the operator. Optionally, the material of the main rod 110 and the auxiliary rod 120 may include plastic.

[0053] In some embodiments of the present application, there are multiple ways to set the interval between the part of the elastic body 121 and the support body 111, that is, there are multiple ways to set the shape of the elastic body 121. Among them, the shape of the elastic body 121 can be any shape that allows the head 122 to move along the first direction X toward the side away from the elastic body 121 when the operator presses the elastic body 121 to reduce the interval between the part of the elastic body 121 and the support body 111.

[0054] In some optional embodiments, the elastic body 121 includes a first segment 121a and a second segment 121b, one end of the first segment 121a is connected to an end of the support body 111 away from the support member 112, the other end of the first segment 121a is connected to the second segment 121b, the head 122 is located at an end of the second segment 121b away from the first segment 121a, and the connection position between the first segment 121a and the second segment 121b is spaced apart from the support body 111, wherein the first segment 121a is inclined in a direction close to the second segment 121b and away from the support body 111, and / or the second segment 121b is inclined toward the support body 111 in a direction close to the head 122.

[0055] By reasonably setting the inclination of the first segment 121a and the second segment 121b, the connection between the first segment 121a and the second segment 121b can be well spaced from the support body 111, so that the operator can press the connection between the first segment 121a and the second segment 121b to gradually approach the support body 111, so that the first segment 121a and the second segment 121b can approach parallelism, which can better drive the head 122 to move along the first direction X toward the side away from the elastic body 121, so that the head 122 can slide into the slide groove 112a through the opening 112b, thereby reducing the volume of the handle 100, and also facilitate the head 122 to slide out of the slide groove 112a through the opening 112b.

[0056] In some optional embodiments, at least two auxiliary rods 120 are disposed on both sides of the main rod 110 in the third direction Z, so that the operator can better grasp the handle 100 and can press the elastic bodies 121 of the two auxiliary rods 120 at the same time, so that when the handle 100 is connected to the shell 200, the two heads 122 can simultaneously move in the slide groove 112a along the first direction X and push the kit 300, thereby improving the driving efficiency of the handle 100 for clamping or shearing the medical opening and closing instrument 10.

[0057] Optionally, the number of the slide grooves 112a is at least two, and the slide grooves 112a are arranged at intervals in the third direction Z. In the working state, the heads 122 of the auxiliary rods 120 are movably arranged in the slide grooves 112a. By arranging the slide grooves 112a to be spaced in the third direction Z, the heads 122 of the auxiliary rods 120 arranged on both sides of the main rod 110 in the third direction Z can be located in different slide grooves 112a, respectively, so that the heads 122 of different auxiliary rods 120 are not likely to interfere with each other.

[0058] Optionally, the head 122 includes a raised rib 122a that is raised on at least one side in the third direction Z. For example, the head 122 includes a raised rib 122a that is raised on the side away from the main rod 110 in the third direction Z, so that when the head 122 contacts the kit 300, the raised rib 122a and the kit 300 can have a better contact area, so as to improve the contact stability between the raised rib 122a and the kit 300, which can facilitate the head 122 to push the kit 300, and the head 122 and the kit 300 are not prone to slippage.
