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.

Example (b):

in this embodiment, as shown in fig. 1 to 8, the auxiliary device for loading and unloading the nail cartridge is specifically a housing having a containing cavity, and specifically includes an end face housing 1, a first side face housing 2, a second side face housing 3, an upper housing 4 and a lower housing 5, four sides of the end face housing 1 are respectively connected to the first side face housing 2, the second side face housing 3, the upper housing 4 and the lower housing 5 to form a nail cartridge end containing cavity 6, wherein the deepest bottom surface of the nail cartridge end containing cavity 6 is the inner surface of the end face housing 1, the length of the lower housing 5 is the shortest, the depth of the nail cartridge end containing cavity 6 depends on the length of the lower housing 5, the rest of the first side face housing 2, the second side face housing 3 and the upper housing 4 are surrounded with the corresponding portion of the lower housing 5 to form the nail cartridge end containing cavity 6, and the upper cavity surface inside the nail cartridge end containing cavity 6 is a portion of the, the lower cavity surface in the nail bin end containing cavity 6 is the inner side surface of the lower shell 5, and the left and right side surfaces of the nail bin end containing cavity 6 are partial inner side surfaces of the first side shell 2 and the second side shell 3. The upper and lower directions in this embodiment correspond to the upper and lower directions in fig. 3, and the left and right directions are directions perpendicular to the paper surface.

Correspondingly, the nail bin comprises a mounting part 8 used for being matched with the nail bin accommodating cavity 10 and a pulling-out end 9 exposed out of the nail bin accommodating cavity 10 after assembly is completed, the width of the nail bin end accommodating cavity 6 is matched with the width of the pulling-out end 9, and the matching is concretely that the width of the nail bin end accommodating cavity 6 is slightly smaller than the width of the pulling-out end 9, so that when the pulling-out end 9 is inserted into the nail bin end accommodating cavity 6, the nail bin end accommodating cavity 6 clamps the pulling-out end 9 relatively, and the nail bin can be relatively fixed with the auxiliary device; in other embodiments, preferably, the two sides of the cartridge end receiving cavity 6 are made of an elastic material at least partially, the distance between the two sides of the cartridge end receiving cavity 6 in the original state is smaller than the width of the pulling end 9, and the maximum distance between the two sides of the cartridge end receiving cavity 6 after elastic deformation is larger than or equal to the width of the pulling end 9.

The inner surface of the upper shell 4 is used for being attached to the upper surface of the nail bin, the nail outlet hole 11 is formed in the upper surface of the nail bin, the upper shell can protect the nails in the nail bin from being polluted, and the nails can be prevented from leaking out of the nail outlet hole. In particular, the length of upper housing 4 is greater than the distance from the end of the cartridge to the most proximal staple exit hole, thus protecting the staples in each staple exit hole. Furthermore, the upper shell 4 is further extended with a nail pushing stopper 7, and the nail pushing stopper 7 is used for stopping the nail pushing piece exposed out of the surface of the nail bin from moving towards the far end. The distal end is the end of the stapler distal to the operator when the operator is holding the stapler.

The first side shell 2 and the second side shell 3 are arranged oppositely, the distance between the first side shell 2 and the second side shell 3 except the nail bin end accommodating cavity 6 is larger than the width of the nail bin mounting part 8, and the length of the lower shell 5 is smaller than or equal to the length of the lower surface of the pulling end 9. Because the length of the lower shell is less than or equal to that of the lower surface of the pull-out end, the nail bin can be smoothly pressed into the nail bin accommodating cavity 10 during installation, and the nail bin can be smoothly pushed out of the nail bin accommodating cavity by upwards pressing the lower shell during disassembly of the nail bin. Further, the distance between the first side shell 2 and the second side shell 3 except the nail bin end accommodating cavity 6 is greater than or equal to the distance between the outer surfaces of the two sides of the nail bin accommodating cavity 10, so that in the installation process, the first side shell 2 and the second side shell 3 cannot be in contact with the outer wall of the nail bin accommodating cavity 10, and the installation of the nail bin is affected. In order to feel softer and prevent sharp edges from damaging the operator, in this embodiment, the outer edges of the first side shell 2 and the second side shell 3 are provided with arc-shaped chamfers.

In order to smoothly pull out the auxiliary device from the pull-out end 9 after the nail bin is mounted, friction parts for increasing friction force are arranged on the outer surfaces of the first side shell 2 and the second side shell 3 of the auxiliary device, specifically, the friction parts can be wavy lines, granular lines or any other lines for increasing friction force, and can also be devices such as a convex part or a handle.

In addition, in the present embodiment, preferably, the upper housing 4 is made of a transparent material, and the condition of the staples inside the staple cartridge and the condition of the final installation of the staple cartridge can be observed at any time by setting the upper housing as the transparent material. In other embodiments, any one of the end surface case 1, the first side surface case 2, the second side surface case 3, the upper case 4, and the lower case 5 may be provided as a transparent material.

The specific implementation process comprises the following steps:

before installation, as shown in fig. 6, the auxiliary device is sleeved on the nail bin, the nail bin is installed in the nail bin accommodating cavity 10 by moving the auxiliary device, as shown in fig. 7, at the moment, the nail bin is installed in the nail bin accommodating cavity, the friction part of the auxiliary device can be held, so that the friction force between the nail bin pulling-out end and the nail bin end accommodating cavity 6 is overcome, the auxiliary device is pulled out of the nail bin, and the installation is finally completed as shown in fig. 8. In addition, before the anastomat is used, the auxiliary device can be still sleeved on the nail bin, the protection effect of the nail bin is achieved, and the nail pushing stop 7 can also prevent the anastomat from being triggered mistakenly.

When the auxiliary device is disassembled, the nail box arranged in the nail box containing cavity is sleeved on the auxiliary device, and the auxiliary device is also shown in fig. 7. At the moment, the nail bin is smoothly pushed out of the nail bin accommodating cavity by pressing the press shell upwards, and the nail bin is taken out along with the auxiliary device.

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.
