Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a simple staple cartridge remover. Background Technology

[0002] Surgical staplers are a commonly used surgical instrument in medicine that replaces manual suturing. Their main working principle is to use a cutting blade to cut the tissue and titanium staples to anastomose the tissue, similar to a stapler.

[0003] Currently, after the stapler completes the anastomosis procedure, a new staple cartridge is required to continue the anastomosis. However, existing staplers use a tight fit between the staple cartridge and the cartridge holder, often requiring considerable force for removal when the surgeon needs to replace the cartridge assembly, causing inconvenience. Furthermore, replacing the cartridge requires the surgeon to apply force to the protruding end of the cartridge, which has a very limited length, resulting in a small area for force application and making removal difficult. Additionally, tissue fluid and blood may adhere to the instruments during surgery, causing slippage and further complicating the removal of the cartridge assembly. Therefore, it is necessary to develop a staple cartridge retrieval device that can easily remove the cartridge from the cartridge holder. Utility Model Content

[0027] 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.

[0028] Example 1

[0029] like Figure 1-7 As shown, a simple staple cartridge remover is used to assist in disassembling the staple cartridge 8. It includes a main board 1, the reverse side 11 of which is the operating part 2. A vertical plate 3 is provided at the center of the front side 12 of the main board 1, which is perpendicular to it. The vertical plate 3 and the front side 12 of the main board located on one side of the vertical plate 3 form an L-shaped abutment. Two baffles 4 protruding from the front side 12 of the main board are also provided on both sides of the vertical plate 3. The two baffles 4 and the abutment form an open disassembly cavity 5. During disassembly, the front end 81 of the staple cartridge is inserted into the disassembly cavity 5. When the bottom surface of the front end 81 of the staple cartridge abuts against the front side 12 of the main board 1 (abutment), and the head of the front end 81 of the staple cartridge abuts against the vertical plate 3, that is, after the front end 81 of the staple cartridge abuts against the abutment, the operating part 2 is pressed in the direction away from the staple cartridge seat 7 to push the staple cartridge 8 upward, so that the staple cartridge 8 is separated from the staple cartridge seat 7.

[0030] Existing staple cartridge disassembly tools typically have a closed side facing the user, making it difficult to determine the contact area and whether the contact point is in place. Furthermore, these tools require the user to lift their elbow upwards to apply force, which is inconvenient and ergonomically inefficient. In contrast, the disassembly cavity 5 of the top-removing device in this embodiment is open to the user and does not contact the top surface of the staple cartridge 8. This allows for easy observation of the contact area between the device and the front end 81 of the staple cartridge. The L-shaped contact area further facilitates accurate identification of the disassembly position. Additionally, the device in this embodiment avoids contact with the used staple cartridge 8 during disassembly, preventing slippage. The addition of the operating section 2 increases the force application area, reducing the force required for disassembly. Furthermore, the upward pressing motion from the bottom of the staple cartridge seat 7 to lift the staple cartridge 8 provides a more ergonomic angle, making operation more effortless and convenient, and enabling rapid disassembly of the staple cartridge.

[0031] Furthermore, the nail remover of this utility model is integrally molded by injection molding, which has a simple structure, is easy to manufacture, and has a low manufacturing cost.

[0032] In the above structure, such as Figure 1 As shown, the vertical plate 3 is connected to two baffles 4 at both ends, and the height of the baffles 4 is not lower than the height of the vertical plate 3. The baffles 4 have rounded corners at both ends to restrict the movement of the front end 81 of the nail cartridge in the disassembly cavity 5 and improve the overall strength of the nail remover.

[0033] To further increase the number of points of force application and improve ease of operation, such as Figure 1-3 As shown, the operating part 2 is further provided with operating expansion parts 21 on both sides. The operating expansion parts 21 are arc-shaped pieces extending along both sides of the main board 1. Specifically, the operating expansion parts 21 are integrally formed with the main board 1 to form an elliptical or circular flat plate. In addition, the surfaces of the operating expansion parts 21 and the operating part 2 are provided with anti-slip textures to prevent slippage when pressed.

[0034] like Figure 1-4 As shown, the mainboard 1 is also provided with a guide part 6 near the abutment part. The guide part 6 includes a guide plate 61 and side plates 62 on both sides of the guide plate 61. The guide plate 61 is flush with the mainboard 1, and the side plates 62 protrude from the front surface 12 of the mainboard and overlap with the baffle 4. Between the two side plates 62 is a guide groove that overlaps with the disassembly cavity 5. The guide groove is clearance-fitted with the staple cartridge seat 7. In this embodiment, the length of the guide part 6 is about half of the staple cartridge seat 7. The guide groove guides the front end 81 of the staple cartridge into the disassembly cavity 5, making the operation more convenient and more ergonomic.

[0035] In addition, such as Figure 5 As shown, the top surface of the side plate 62 is not higher than the snap-fit ​​groove 71 on the staple cartridge seat 7, which makes it easy to confirm the separation status of the staple cartridge 8 and the staple cartridge seat 7.

[0036] The working principle of this utility model is as follows: When in use, support the far end of the staple cartridge seat with one hand, and let the front end 81 of the staple cartridge slide from the guide part 6 into the disassembly cavity 6 with the other hand. After the front end 81 of the staple cartridge abuts against the abutting part, press the operating part 2 and / or the operating expansion part in the direction away from the staple cartridge seat 7 to push the staple cartridge 8 upward, so that the staple cartridge 8 is separated from the staple cartridge seat 7.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
