Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

In the description of the present application, it is to be understood that the terms "upper", "lower", "top", "bottom", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application. Wherein proximal refers to the end of the medical device that is closer to the operator and distal refers to the end that is closer to the patient.

Example (b):

in this embodiment, as shown in fig. 1-3, an end detachable stapler nail supporting plate is disclosed, wherein specifically, the end detachable stapler nail supporting plate includes a nail supporting plate main body 1, the nail supporting plate main body 1 is generally used for being hinged to a nail bin accommodating portion, a hinge shaft 3 hinged to a nail bin installing portion of the stapler is arranged at a near end of the nail supporting plate main body, the nail supporting plate main body 1 includes a nail supporting surface corresponding to the nail bin, specifically, a nail supporting groove 11 and a push-type broach groove 12 are respectively arranged on the nail supporting surface, the nail supporting groove 11 and a nail outlet hole of the nail bin are opposite to each other, when a nail is discharged in an anastomosis process, the nail is deformed when encountering the nail supporting groove 11, so that a bent fixed tissue is realized. The knife pusher 12 is adapted to cooperate with a knife passing through the cartridge, which is not described in detail herein for the prior art.

The improvement point of the application lies in that a separation auxiliary block 2 detachably connected with the far end of the nail propping plate main body 1 is provided, specifically, the separation auxiliary block 2 is integrally formed and made of elastic high polymer material, wherein the elastic high polymer material can be rubber or plastic and the like, and preferably has biocompatibility.

Further, the auxiliary separating block 2 is provided with an inserting block 21 and a bending end 22, the bending end 22 bends towards the vertical direction of the nail propping surface, the outer diameter of the bending end 22 is reduced from the near end to the far end, the inserting block 21 is inserted into the cutter pushing groove 12, the auxiliary separating block is manufactured through integral forming and is made of an elastic high polymer material, the auxiliary separating block is inserted into the cutter pushing groove after being deformed conveniently, the inserting block does not need to be additionally fixed, and the structure is effectively prevented from being damaged after being stressed.

Specifically, in order to cooperate with an existing push broach slot, in this embodiment, the width of the push broach slot 12 is unchanged from the opening of the push broach slot 12 to the bottom surface of the push broach slot 12, the width of the insertion block 21 is reduced from the opening of the push broach slot 12 to the bottom surface of the push broach slot 12, that is, the nail resisting surface is in a tapered structure with a large top and a small bottom in the direction of the outer surface, and the minimum width of the insertion block 21 in an uncompressed state is the same as the width of the push broach slot 12, so that the insertion is convenient, the insertion block 21 is beneficial to being led into the push broach slot 12 after being extruded and deformed in the insertion process, and finally, after the installation is completed, the push broach slot 12 is in interference fit with the insertion block 21. The inserting block of the separation auxiliary block is directly arranged to be in inserting fit with the push broach slot, so that a connecting structure is omitted, and the stability of the structure is guaranteed against falling off by the aid of the interference fit. Moreover, since the bending end 22 is bent toward the direction perpendicular to the nail abutting surface and the direction is opposite to the direction in which the insertion block 21 becomes smaller, when the tissue is separated by operation, the pressure received by the bending end 22 can further help to compress the insertion block 21 downward, and the insertion block 21 will not be separated from the push broach slot 12.

In this embodiment, it is further preferable that the surface of the distal end of the nail abutting plate main body 1 matches the surface of the auxiliary block provided with the insertion block 21, so that there is no gap between the two after the assembly is completed, and the height of the insertion block 21 is equal to the depth of the push-in slot 12, so that the surface after installation is even.

In this embodiment, it is further preferable that the material of the separation auxiliary block 2 is a transparent material, and by setting the separation auxiliary block to be a transparent material, the tissue to be separated can be clearly observed during the operation, and can be separated after being accurately positioned.

In addition, the anastomat is further protected and comprises a nail bin installation part and the anastomat nail abutting plate with the detachable end part, and the hinged shaft 3 is hinged with the nail bin installation part.

As described above, the present invention has been explained in full in accordance with the gist of the present invention, but the present invention is not limited to the above-described embodiments and implementation methods, and features of the embodiments may be combined with each other without contradiction. The practitioner of the related art can make various changes and implementations within the scope permitted by the technical idea of the present invention.
