Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a novel stapler cartridge removal device. Background Technology

[0002] The laparoscopic stapler includes a laparoscopic assembly, the distal end of which includes a staple cartridge assembly and an anvil assembly. The staple cartridge assembly includes a staple cartridge and a staple cartridge holder. Minimally invasive surgeries often use laparoscopic staplers to cut and suture tissue. Each surgery typically uses multiple staple cartridge assemblies, so a new staple cartridge assembly needs to be replaced after each cut and suture to continue the surgical procedure. Because the staple cartridge and holder are tightly fitted together, surgeons often need considerable force to remove them when replacing the staple cartridge assembly, causing inconvenience. Therefore, a staple cartridge removal device is required to remove the staple cartridge from the staple cartridge holder.

[0003] Existing staple cartridge removal devices are used on staplers where the staple cartridge assembly is fixed and the anvil assembly is movable. When using existing staple cartridge removal devices to remove the staple cartridge from a stapler where the anvil assembly is fixed and the staple cartridge assembly is movable, the staple cartridge assembly rotates, requiring the staple cartridge assembly to be held down and a large force to be applied to the staple cartridge to complete the removal. This removal process is laborious and can easily cause the staple cartridge to fall out. After falling out, it needs to be handled by medical staff, and the contaminated staple cartridge assembly will also contaminate the hands of medical staff. Utility Model Content

[0004] The purpose of this invention is to provide a novel stapler cartridge removal device that can remove the stapler cartridge with minimal effort, and the stapler cartridge will not fall off after removal.

[0005] According to the present invention, a novel stapler cartridge disassembly device includes a fixed component and a movable component. The fixed component and the movable component are respectively provided with a first end and a second end opposite to each other. The first end of the movable component is rotatably connected to the first end of the fixed component. The first end of the fixed component is provided with an opening. The bottom of the opening is provided with a support portion for abutting against the bottom of the staple cartridge frame. The movable component is provided with at least one first abutting portion abutting against the side of the staple cartridge frame and a second abutting portion abutting against the bottom of the staple cartridge.

[0006] In actual use, the staple cartridge holder and staple cartridge are inserted into the opening together, with the bottom of the staple cartridge holder placed on the support. The first abutment abuts against both sides of the staple cartridge, and the bottom of the staple cartridge on the staple cartridge holder is placed on the second abutment. Then, keeping the fixed part stationary, the movable part is rotated towards the fixed part. Since the support and fixed part remain stationary, the first abutment has a downward pressure on the staple cartridge holder, eventually abutting against and pressing against the staple cartridge holder. The second abutment, which abuts against the bottom of the staple cartridge, rotates with the movable part, thereby lifting the staple cartridge and finally separating the staple cartridge from the staple cartridge holder to complete the disassembly. The whole process is time-saving and labor-saving.

[0007] Furthermore, it also includes a reset mechanism that resets the moving part after it has rotated to the correct position.

[0008] Furthermore, the reset mechanism is a reset spring, with the first end of the reset spring connected to the fixed member and the second end of the reset spring connected to the movable member.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0017] Combination Figures 1 to 4This invention discloses a novel stapler cartridge disassembly device, comprising a fixed member 1 and a movable member 2. The fixed member 1 and the movable member 2 are respectively provided with a first end and a second end. The first end of the movable member 2 is rotatably connected to the first end of the fixed member 1. The first end of the fixed member 1 has an opening 3, and the bottom of the opening 3 is provided with a support part 4 for abutting against the bottom of the staple cartridge frame. The fixed member 1 is provided with at least one first abutting part 5 abutting against the side of the staple cartridge frame 9, and the movable member 2 is provided with a second abutting part 6 abutting against the bottom of the staple cartridge.

[0018] It is worth noting that in the initial state, the bottom of the staple cartridge may not abut against the movable part 2. After the movable part 2 is rotated into place, the bottom of the staple cartridge abuts against the movable part 2.

[0019] Combination Figure 5 In actual use, the staple cartridge holder 9 and staple cartridge 10 are inserted into the opening 3 together. The bottom of the staple cartridge holder is placed on the support part 4, the first abutment part 5 abuts against both sides of the staple cartridge holder, and the bottom of the staple cartridge on the staple cartridge holder is placed on the second abutment part 6. Then, keeping the fixing part 1 stationary, the movable part 2 is rotated towards the fixing part 1. Since the support part 4 and the fixing part 1 remain stationary, the first abutment part 5 has a tendency to press down on the staple cartridge holder 9, and finally abuts against and presses against the staple cartridge holder 9. The second abutment part 6, which abuts against the bottom of the staple cartridge, rotates with the movable part 2, thereby lifting the staple cartridge and finally separating the staple cartridge from the staple cartridge holder to complete the disassembly. The whole process is time-saving and labor-saving.
