Description

Technical Field

[0001] The utility model relates to the technical field of medical components, and specifically relates to a staple cartridge assembly of a medical stapler. Background Art

[0002] In the field of medical surgery, as an important surgical instrument, a stapler is widely used in various surgeries that require tissue anastomosis. The stapler uses titanium staples through its internal staple cartridge assembly to quickly and accurately anastomose tissues, greatly improving the surgical efficiency and success rate. However, during actual use, the staple cartridge assembly is directly exposed to the surgical environment and is easily eroded by pollutants such as blood and tissue fluid. This not only may affect the normal operation of the staple cartridge assembly but also may increase the risk of surgical infection.

[0003] In addition, since the stapler needs to withstand a certain amount of pressure and impact during operation, the sealing performance of the staple cartridge assembly is also particularly important. If the sealing effect is not good, it may cause gas or liquid leakage, thereby affecting the surgical effect and the safety of the patient. Therefore, how to effectively protect the staple cartridge assembly while ensuring its good sealing performance has become an urgent problem to be solved in the current field of medical staplers. Summary of the Utility Model

Detailed Description of the Invention

[0019] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0020] This embodiment provides a staple cartridge assembly for a medical stapler, which is mainly used for tissue anastomosis operations in medical surgical procedures. By providing a silicone protective sleeve 1 and a sealing mechanism 4, the purpose of protecting the staple cartridge assembly 5 from being eroded by pollutants is achieved, thereby improving the surgical hygiene and safety. At the same time, by tightly fitting the silicone sealing ring 405 with the second card slot 8 inside the mounting block 6, it is ensured that the staple cartridge assembly has good sealing performance, effectively preventing the leakage of gas or liquid, and further ensuring the safety of the surgical process and the health of the patient. In addition, the ingenious design of the reinforcing ribs 2 and the first groove 3 and the second groove 7 not only enhances the structural stability and durability of the staple cartridge assembly, but also greatly improves the convenience of operation.

[0021] See Figures 1 to 5 , a staple cartridge assembly for a medical stapler, comprising a silicone protective sleeve 1. A sealing mechanism 4 is provided at the left end of the silicone protective sleeve 1. The sealing mechanism 4 includes a concave ring sleeve 401, and the concave ring sleeve 401 is fixedly connected to the outer surface of the left end of the silicone protective sleeve 1. A first card slot 402 is provided inside the concave ring sleeve 401. A fixing ring 403 is fixedly connected inside the first card slot 402. A silicone sealing sleeve 404 is fixedly connected to the outer surface of the fixing ring 403. A silicone sealing ring 405 is fixedly connected to the inner side of the silicone sealing sleeve 404. A round rod 406 is fixedly connected to the outer surface of the silicone sealing ring 405. One end of the round rod 406 away from the silicone sealing ring 405 is fixedly connected to a rubber pulling block 407.

[0022] A staple cartridge assembly entity 5 is provided inside the silicone protective sleeve 1, and a mounting block 6 is installed at the left end of the staple cartridge assembly entity 5.

[0023] A second card slot 8 is provided inside the mounting block 6, and the second card slot 8 is sealed with the outer surface of the silicone sealing ring 405.

[0024] Four reinforcing ribs 2 are fixedly connected to the outer surface of the silicone protective sleeve 1 and are fixedly connected to the concave ring sleeve 401.

[0025] A first groove 3 and a second groove 7 are provided on the outer surface of the right end of the silicone protective sleeve 1 and are symmetrically arranged up and down.

[0026] The silicone protective cover 1 is tightly fitted around the staple cartridge assembly, effectively blocking the erosion of external pollutants such as blood and tissue fluid on the staple cartridge assembly, thus significantly reducing the risk of surgical infection and ensuring the hygiene of the surgery. At the same time, the sealing mechanism 4, especially the silicone sealing ring 405, provided at the left end of the silicone protective cover 1, can form a tight seal with the second card slot 8 inside the mounting block 6 during installation, effectively preventing the leakage of gas or liquid, and further ensuring the safety of the surgical process and the patient.

[0027] Through the provided reinforcing ribs 2, the stability and durability of the structure are enhanced, the risk of deformation or damage is reduced, and thus the service life is extended. At the same time, the settings of the first groove 3 and the second groove 7 not only improve the flexibility of the silicone protective cover 1 but also facilitate the holding and operation of medical staff. In addition, when it is necessary to disassemble the silicone sealing ring 405, by pinching the rubber pull block 407 and pulling it outwards, the silicone sealing ring 405 can be easily removed from the second card slot 8, simplifying the maintenance process and improving work efficiency.

[0028] Working principle: The silicone protective cover 1, as the core protective component of the present utility model, closely fits around the periphery of the staple cartridge assembly entity 5, providing it with comprehensive protection measures. Due to the excellent elasticity and corrosion resistance of the silicone material, it can effectively block various pollutants in the external environment, thus avoiding potential damage to the staple cartridge assembly caused by these pollutants. A sealing mechanism 4 is equipped at the left end of the silicone protective cover 1, which is an important link to ensure excellent sealing performance. The sealing mechanism 4 includes components such as a concave ring sleeve 401, a fixing ring 403, a silicone sealing sleeve 404, a silicone sealing ring 405, a round rod 406, and a rubber pull block 407. When the staple cartridge assembly is installed on the stapler, the sealing mechanism 4 can be tightly engaged with the second card slot 8 inside the mounting block 6 to construct an effective sealing barrier. Especially the silicone sealing ring 405 can deform when subjected to external force, filling possible tiny gaps to prevent the penetration of gas or liquid. When it is necessary to disassemble the silicone sealing ring 405 from the mounting block 6 and then remove the entire protective cover, the operator can pinch the rubber pull block 407 and pull it outwards. Through this action, a notch will be generated on the silicone sealing ring 405 under the action of external force. At this time, the operator can insert a finger into the notch and easily disengage the silicone sealing ring 405 from the second card slot 8, thus conveniently removing the entire protective cover assembly. The mounting block 6 plays a crucial role in connecting the staple cartridge assembly and the stapler. The second card slot 8 opened therein closely fits the outer surface of the silicone sealing ring 405, further enhancing the overall sealing effect. The reinforcing rib 2 is firmly fixed on the outer surface of the silicone protective cover 1 and is connected to the concave ring sleeve 401. Such a structure significantly improves the structural stability and durability of the silicone protective cover 1, effectively reducing the risk of deformation or damage. The first groove 3 and the second groove 7 are cleverly arranged on the outer surface of the right end of the silicone protective cover 1, presenting an up-and-down symmetrical layout. This design not only enhances the flexibility of the silicone protective cover 1 but also provides great convenience for holding and operation.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
