DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1-3 As shown, this embodiment proposes a laparoscopic stapler, including a cavity wall driving handle 1, a clamp rod angle adjustment assembly 2, a laparoscopic stapler housing 3 and a stapler jaw rod 4. The stapler jaw rod 4 is replaceable and detachable at the input end of the laparoscopic stapler housing 3, and also includes a jaw rod fixing assembly 5. The jaw rod fixing assembly 5 includes:

[0025] A rod wrapping block 6, which is fixed to the input end of the laparoscopic stapler housing 3;

[0026] The wrapping block 7 can be sleeved on the outer wall of the rod wrapping block 6. After the wrapping block 7 is completely sleeved on the outer wall of the rod wrapping block 6, the inner wall of the rod wrapping block 6 shrinks. After the inner wall is shrunk, the rod wrapping block 6 fixes the outer wall of the anastomosis jaw rod 4.

[0027] A pull block is provided below the existing laparoscopic stapler housing 3 , and the stapler jaw rod 4 can be disassembled by pulling the pull block.

[0028] Furthermore, a plurality of groups of reducing grooves 8 are provided on the surface of the rod wrapping block 6 , and the plurality of groups of reducing grooves 8 are arranged in a ring array, and the shape of the wrapping block 7 is conical.

[0029] Furthermore, the wrapping block 7 includes a first block 18 and a second block 9, a first connecting block 10 is fixed to the outer wall of the first block 18, a second connecting block 11 is fixed to the outer wall of the second block 9, a protrusion 12 is fixed to the surface of the first connecting block 10, and a groove 13 adapted to the protrusion 12 is opened through the surface of the second connecting block 11.

[0030] Furthermore, the outer wall of the rod wrapping block 6 is provided with a first thread 14 , and the inner wall of the wrapping block 7 is provided with a tapered thread 15 that matches the first thread 14 .

[0031] Furthermore, it also includes an inner ring gasket and an outer ring gasket. The outer ring gasket is sleeved on the jaw rod 4 of the anastomosis device, and the inner ring gasket is sleeved on the inner wall of the wrapping block 7. The inner ring gasket and the outer ring gasket are in contact to increase the stability during fixation.

[0032] The working principle is to avoid special accidents of the stapler jaw rod 4 during operation. Because the internal structure cannot be observed, the user cannot feel the connection structure between the stapler jaw rod 4 and the laparoscopic stapler shell 3 during use. There have been cases where the stapler jaw rod 4 fell off during use by the staff. The user found that the stapler jaw rod 4 can change the angle and use it during use. Later, it was found that the stapler jaw rod 4 driving member position is still connected with the cavity wall driving handle 1 and the jaw rod angle adjustment component 2. The reason for the stapler jaw rod 4 falling off is that the interior of the laparoscopic stapler shell 3 and the fixed end of the stapler jaw rod 4 are loose. In order to ensure the stability of the overall fixed position of the stapler jaw rod 4, the laparoscopic stapler needs to be replaced. The stapler jaw rod 4 can be removed by pushing the push block under the laparoscopic stapler housing 3. When consumables need to be replaced and the laparoscopic stapler needs to be used in time, the stapler jaw rod 4 can be installed on the input end of the stapler housing and then fixed by the pull block. After the stapler jaw rod 4 is fixed, the first block 18 and the second block 9 are put on the outer wall of the stapler jaw rod 4, and then the first connecting block 10 of the first block 18 and the second connecting block 11 of the second block 9 are connected. Then, the wrapping block 7 is threadedly connected to the outside of the rod wrapping block 6. The wrapping block 7 is conical in shape. When the wrapping block 7 is connected to the rod wrapping block 6, the opening becomes smaller and smaller during the connection process, and the inner wall of the rod wrapping block 6 is reduced. The rod wrapping block 6 with the reduced inner wall fixes the outer wall of the stapler jaw rod 4. When replacing, just unscrew the wrapping block 7.

[0033] Example 2

[0034] Please refer to 1. Figure 2 、 Figure 5 As shown, a clamping block 16 is fixed to one end of the rod wrapping block 6 , and a clamping groove 17 adapted to the clamping block 16 is provided on the surface of the wrapping block 7 .

[0035] When replacing the stapler jaw rod 4, the first block 18 and the second block 9 are similarly sleeved on the outer wall of the stapler jaw rod 4, and the clamping block 16 is docked with the clamping groove 17. Since the wrapping block 7 is conical, the shrinkage of the rod wrapping block 6 will be closed, and the rod wrapping block 6 will fix the stapler jaw rod 4.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
