Automatic multi-shot plastic blood vessel serrefine and serrefine case

Abstract

The invention discloses an automatic multi-shot plastic blood vessel serrefine and a serrefine case. The automatic multi-shot plastic blood vessel serrefine comprises a serrefine mouth mechanism, a case containing mechanism, an automatic serrefine delivery mechanism, a serrefine applying mechism and a handle mechanism. By means of the automatic multi-shot plastic blood vessel serrefine and the serrefine case, the operation speed can be obviously and effectively improved, namely a doctor only needs to put an automatic multi-shot applied serrefine into a human body in one time to perform multiple-time continuous serrefine applying and does not need to take an instrument from the human body in the operation process. In addition, the operation time waste for instrument transfer between the operation doctor and a nurse and installation is avoided by means of the structure, operation risk is reduced, the multi-shot plastic blood vessel serrefine is capable of performing opening-closing motion and can be inversely buckled to achieve self locking, a large blood vessel ligation and closing are easy, blood vessel alignment is easier, operation is more convenient to perform, the closed blood vessel is firm, and quality is improved obviously. Furthermore, the automatic multi-shot plastic blood vessel serrefine can be disinfected for multiple times and repeatedly used, the serrefine case is disposable, and therefore product cost is low.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an automatic continuous-fire plastic blood vessel clamp and a clip box suitable for tightening and closing blood vessels in human surgery and minimally invasive surgery. Background technique [0002] For a long time, there are two types of vascular ligation medical devices that dominate the international and domestic markets. One is a reusable single-shot absorbable ligation clip applicator. In human endoscopic surgery, although the reusable single-shot absorbable ligation clip applier can effectively ligate blood vessels and can be reused after disinfection, it needs to be passed between surgeons and nurses during use , that is, after the surgeon has clipped a biological clip, he needs to take the clip applier out of the human body, then remove the clip applicator assembly on the entire head of the clip applier, and pass it to the nurse to complete a new clip appli...

Problems solved by technology

When the U-shaped clips with these two characteristics are used to ligate blood vessels, because the ligation clip is a U-shaped clip, one end is connected and fixed, and the other end relies on the elasticity of metal or pl
