Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 -5. The present invention provides a technical solution: a laparoscopic cutting stapler for complete cutting, comprising a stapler shell 1, the inner wall of the stapler shell 1 is provided with a fixing mechanism 2, and the outer wall of the stapler shell 1 is provided with a mounting mechanism 3.

[0025] The fixing mechanism 2 includes a fixing plate 21, a circular groove 22, a telescopic column 23, a first spring 24, a clamping plate 25 and an anti-slip nail 26. The fixing plate 21 is installed on the outside of the stapler housing 1. The bottom wall of the fixing plate 21 is provided with a circular groove 22. The inside of the circular groove 22 is provided with a telescopic column 23. The outside of the telescopic column 23 is provided with a first spring 24. The bottom wall of the telescopic column 23 is fixed with a clamping plate 25. The bottom wall of the clamping plate 25 is provided with an anti-slip nail 26. By setting the fixing plate 21, the circular groove 22, the telescopic column 23, the first spring 24, the clamping plate 25 and the anti-slip nail 26, when in use, when it is necessary to fix the gastrointestinal tract Timing, first extend the stapler into the patient's body, align the splint 25 with the gastrointestinal tract, press the use button of the stapler shell 1, and when cutting the gastrointestinal tract, fix it to one end of the stapler shell 1 through the fixing plate 21, and then the anti-slip nails 26 under the splint 25 fix the gastrointestinal tract to prevent it from slipping, and at the same time, the contraction of the first spring 24 drives the telescopic column 23 to contract. At this time, the upper part of the splint 25 is tightly fitted with the fixing plate 21, and the lower part and the anti-slip nails 26 fix the gastrointestinal tract, the telescopic column 23 limits the first spring 24, and the circular groove 22 limits the telescopic column 23 and the first spring 24, thereby fixing the gastrointestinal tract.

[0026] Furthermore, the mounting mechanism 3 includes a mounting plate 31, a limiting rod 32, an elastic block 33, a threaded cavity 34, a mounting tube 35, a slide groove 36 and a second spring 37. The mounting plate 31 is mounted on the outside of the stapler housing 1. The mounting plate 31 is internally slidably connected to the limiting rod 32. The elastic block 33 is fixed to one end of the limiting rod 32. The stapler housing 1 is provided with a threaded cavity 34. The threaded cavity 34 is internally threadedly connected to the mounting tube 35. The outer wall of the stapler housing 1 is provided with a slide groove 36. The slide groove 36 is provided with a second spring 37. By arranging the mounting plate 31, the limiting rod 32, the elastic block 33, the threaded cavity 34, the mounting tube 35, the slide groove 36 and the second spring 37, when in use, when the mounting tube 35 needs to be installed, the mounting tube 35 is rotated. The tube 35 is threadedly connected to the inner threaded cavity 34 of the stapler shell 1, and then the limiting rod 32 inside the mounting plate 31 is aligned with the circular hole on the outer wall of the stapler shell 1, and the limiting rod 32 is pushed to pass the limiting rod 32 through the mounting plate 31 and the stapler shell 1. At the same time, the thrust of the limiting rod 32 causes the elastic block 33 to shrink during the penetration process, so that the elastic block 33 and the limiting rod 32 fix the mounting plate 31 and the stapler shell 1. When the mounting plate 31 needs to be removed, the limiting rod 32 is pulled to remove the elastic block 33 from the stapler shell 1, and the slider below the limiting rod 32 is driven by the contraction of the second spring 37. The slider below the limiting rod 32 will move inward in the slide groove 36, and then the slider drives the limiting rod 32 to be stored and engaged with the inside of the mounting plate 31, thereby installing the mounting tube 35.

[0027] Furthermore, circular grooves 22 are opened at equal intervals on the bottom wall of the fixed plate 21, and the telescopic columns 23 are distributed at equal intervals inside the circular grooves 22. Through the setting of the circular grooves 22, the upper part of the splint 25 is tightly fitted with the fixed plate 21, and the lower part fixes the gastrointestinal tract with the anti-slip nails 26. The telescopic column 23 limits the first spring 24, and the circular grooves 22 limit the telescopic column 23 and the first spring 24.

[0028] Furthermore, the first springs 24 are evenly spaced outside the telescopic column 23, and the anti-slip spikes 26 are evenly spaced on the bottom wall of the splint 25. Through the setting of the splint 25, the stapler is extended into the patient's body, the splint 25 is aligned with the gastrointestinal tract, and the use button of the stapler shell 1 is pressed. When the gastrointestinal tract is cut, the fixing plate 21 is fixed to one end of the stapler shell 1, and the anti-slip spikes 26 under the splint 25 fix the gastrointestinal tract to prevent it from slipping. The contraction of the first spring 24 drives the telescopic column 23 to contract.

[0029] Furthermore, the mounting plate 31 is symmetrically arranged with respect to the central axis of the mounting tube 35, and the limiting rod 32 is symmetrically arranged with respect to the central axis of the mounting tube 35. Through the arrangement of the mounting plate 31, when the mounting plate 31 is removed, the limiting rod 32 is pulled to remove the elastic block 33 from the stapler shell 1, and the contraction of the second spring 37 drives the slider below the limiting rod 32, and the slider below the limiting rod 32 moves inward in the slide groove 36, and the slider drives the limiting rod 32 to be stored and engaged with the inside of the mounting plate 31.

[0030] Furthermore, the mounting plate 31 is connected to the stapler shell 1 through a limiting rod 32, and the limiting rod 32 and the mounting plate 31 form a sliding structure. Through the setting of the limiting rod 32, the limiting rod 32 inside the mounting plate 31 is aligned with the circular hole on the outer wall of the stapler shell 1, and the limiting rod 32 is pushed to penetrate the mounting plate 31 and the stapler shell 1. The thrust of the limiting rod 32 causes the elastic block 33 to shrink during the penetration process, so that the elastic block 33 and the limiting rod 32 fix the mounting plate 31 and the stapler shell 1.

[0031] Furthermore, the threaded cavity 34 and the mounting tube 35 form a rotating structure, and the second spring 37 is symmetrically arranged with respect to the central axis of the mounting tube 35. Through the arrangement of the mounting tube 35, the mounting tube 35 can be rotated and threadedly connected to the threaded cavity 34 inside the anastomosis shell 1 through the mounting tube 35.

[0032] Working principle: First, when it is necessary to fix the stomach and intestine, the stapler is inserted into the patient's body, the splint 25 is aligned with the stomach and intestine, and the use button of the stapler shell 1 is pressed. When cutting the stomach and intestine, it is fixed to one end of the stapler shell 1 through the fixing plate 21, and then the anti-slip nails 26 under the splint 25 fix the stomach and intestine to prevent the stomach and intestine from slipping. At the same time, the contraction of the first spring 24 drives the telescopic column 23 to contract. At this time, the upper part of the splint 25 is tightly fitted with the fixing plate 21, and the lower part and the anti-slip nails 26 fix the stomach and intestine. The telescopic column 23 limits the first spring 24, and the circular groove 22 limits the telescopic column 23 and the first spring 24, so as to fix the stomach and intestine. When it is necessary to install the mounting tube 35, the mounting tube 35 is rotated and connected to the mounting tube 35 through a thread. The inner threaded cavity 34 of the stapler shell 1 is then aligned with the circular hole on the outer wall of the stapler shell 1 by the limiting rod 32 inside the mounting plate 31, and the limiting rod 32 is pushed to pass the limiting rod 32 through the mounting plate 31 and the stapler shell 1. At the same time, the thrust of the limiting rod 32 causes the elastic block 33 to shrink during the penetration process, so that the elastic block 33 and the limiting rod 32 fix the mounting plate 31 and the stapler shell 1. When the mounting plate 31 needs to be removed, the limiting rod 32 is pulled to remove the elastic block 33 from the stapler shell 1, and the sliding block below the limiting rod 32 is driven by the contraction of the second spring 37. The sliding block below the limiting rod 32 will move inward in the slide groove 36, and then the sliding block drives the limiting rod 32 to be stored and engaged with the inside of the mounting plate 31, thereby installing the mounting tube 35.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
