Technical Field

[0001] This utility model relates to the field of laparoscopic cutting stapler technology, and in particular to a quick blade replacement device for laparoscopic cutting stapler. Background Technology

[0002] The laparoscopic cutting and anastomosis device is a minimally invasive surgical instrument used to simultaneously cut and suture tissue during laparoscopic and other endoscopic surgeries. It has the advantages of precision, efficiency, and reduced intraoperative bleeding.

[0003] For example, the cutting blade of a laparoscopic cutting anastomosis device disclosed in patent publication number CN211066819U can accelerate the welding and fixing of the push plate, and can also effectively improve the firmness and stability of the blade installation, avoiding the existence of safety hazards;

[0004] When fixing the connecting block to the blade head, the design of the trapezoidal mounting block and the trapezoidal mounting groove is used to connect the connecting block and the blade head. However, during the connection, the mounting block may slide inside the mounting groove, which will affect subsequent use. Therefore, this solution proposes a quick-change device for the blade of a laparoscopic cutting stapler to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-4 The device shown is a quick-change device for a laparoscopic stapler blade, applied to blade 1. A stapler pusher plate 2 is provided on one side of blade 1, comprising:

[0027] Cutter head 3 is sleeved on one side of blade 1;

[0028] Connecting block 4 is located on one side of the stapler push plate 2, and a positioning element 8 is provided on one side of the connecting block 4;

[0029] The tool holder 5 is located on one side of the tool head 3, and a second mounting part 9 is provided on one side of the tool head 3;

[0030] The first mounting component 6 is disposed on one side of the cutter head 3;

[0031] The pusher 7 includes a pressing block 702 disposed on one side of the first mounting member 6, a sliding block 703 disposed on one side of the pressing block 702, and an elastic block 705 disposed on one side of the sliding block 703.

[0032] It should be noted that the blade 1 is fixedly connected to one side of the blade head 3. During use, the position of the blade 1 is fixed by fixing the position of the blade head 3. The elastic block 705 is made of rubber, so that the elastic block 705 will deform when it is squeezed. When the blade head 3 and the connecting block 4 are connected by the first mounting part 6, the elastic block 705 drives the pressing block 702 to push the connecting block 4 and the blade head 3 to the opposite position. This design increases the friction at the connection between the two and reduces the wobbling of the blade head 3 on the side of the connecting block 4.

[0033] Specifically, the first mounting component 6 includes a first mounting block 601 fixedly connected to one side of the cutter head 3, and a first mounting groove 602 is provided on one side of the connecting block 4. The first mounting block 601 is inserted into the interior of the first mounting groove 602. The second mounting component 9 includes a second mounting block 902 symmetrically fixedly connected to the top and bottom of the cutter head 3. The cutter holder 5 has a second mounting groove 901 on the side near the cutter head 3. The second mounting block 902 is inserted into the interior of the second mounting groove 901. The horizontal longitudinal section of the second mounting groove 901 and the second mounting block 902 are both set to T-shape. The second mounting groove 901 and the second mounting block 902 are used to connect the cutter head 3 and the cutter holder 5.

[0034] It should be noted that the first mounting block 601 on the cutter head 3 is fixedly connected to the first mounting groove 602 on the connecting block 4, and the second mounting block 902 is fixedly connected along the second mounting groove 901, thereby connecting the connecting block 4 and the cutter head 3. By setting the first mounting block 601 and the first mounting groove 602 to be trapezoidal, the connection stability between the connecting block 4 and the cutter head 3 is improved. By mounting the blade 1 on the cutter head 3, the cutter head 3 and the blade 1 are pushed to work by the anastomosis pusher plate 2.

[0035] Specifically, an outlet groove 701 is provided on the inner wall of one side of the first mounting groove 602, and the extrusion block 702 is inserted into the inside of the outlet groove 701. A cavity 704 is provided on the inner wall of one side of the outlet groove 701, and the sliding block 703 is inserted into the inside of the cavity 704. An elastic block 705 is fixedly connected to the inner wall of one side of the cavity 704.

[0036] It should be noted that the two sides of the extrusion block 702 are inclined surfaces. When the first mounting block 601 is inserted into the first mounting groove 602, the first mounting block 601 pushes the inclined surfaces of the extrusion block 702 and pushes the extrusion block 702 away from the first mounting block 601.

[0037] Specifically, the positioning component 8 includes a positioning block 802 fixedly connected to one side of the stapler push plate 2, and a positioning groove 801 is provided on one side of the connecting block 4, with the positioning block 802 inserted into the interior of the positioning groove 801.

The positioning groove 801 on the connecting block 4 is aligned with the positioning block 802 on the stapler push plate 2 and slidably connected. Finally, the stapler push plate 2 and the connecting block 4 are installed and fixed by welding or bonding.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
