Description

TECHNICAL FIELD

[0001] The utility model relates to surgical appliance, especially a surgical clip applier. BACKGROUND

[0002] The clip applier is a commonly used instrument in the surgical process, which is usually composed of a clamp head and a handle, and the clamp head is driven to act by the handle opening and closing.

[0003] The current clip applier has a relatively simple connection between the clamp head and the handle, and is usually fixedly connected and cannot be simply disassembled. The clamp head is directly used, and is more likely to be worn out than other components such as the handle. Once the clamp head is worn out, it is usually discarded, otherwise it is extremely easy to cause problems and accidents during the operation if it is continuously used.

[0004] Because the clamp head and the handle of the existing clip applier are usually inconvenient to disassemble, the entire clip applier can only be discarded as a whole when it is discarded, resulting in a relatively high cost of the clip applier. The handle and other components of the clip applier are not as easy to wear as the clamp head, and the discarding of these still usable components together with the clamp head is inevitably a waste of resources.

[0005] It is of great significance to design a clip applier with a clamp head that is convenient to disassemble and replace to solve the above problems. CONTENT OF THE UTILITY MODEL
