Continuous-mounting type clip applicator

Abstract

The invention discloses a continuous-mounting type clip applicator. The continuous-mounting type clip applicator comprises a fixed handle, a conveying handle, a clip-closing handle, a pushing mechanism, a clip tube, a clip head and a closed clamp assembly, wherein a filling groove is formed in the clip tube; the closed clamp assembly is detachably arranged in the filling groove; the clip tube comprises an outer clip tube and an inner clip tube; the conveying handle and the clip-closing handle are hinged with the fixed handle; through linkage between the clip-closing handle and the outer clip tube, opening or closing of the clip head can be controlled; the closed clamp assembly comprises a plurality of closed clips; and the conveying handle is linked with the pushing mechanism so as to be moved in the length direction of the inner clip tube, and thus, the closed clips are driven to be moved in the direction of the clip head. The continuous-mounting type clip applicator provided by the invention has the advantages that the closed clamp assemblies of different specifications and quantities can be selected to be mounted according to the categories of surgery in a surgical process, andbody lumen tissues can be quickly, conveniently and continuously closed, and therefore, the surgery infection risk of patients can be reduced, the operation efficiency is greatly improved, the treatment timeliness is promoted, and the workload of medical personnel is alleviated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a continuous-fire clip applier. Background technique [0002] In minimally invasive surgery, closure clips are often used to clamp human blood vessels and other luminal tissues, and the closure clips need to be used in conjunction with special clip appliers. At present, the clip applier used in conjunction with the closure clip is a single-shot clip applier, and the clip applier can only clamp and install one closure clip at a time for surgical use. However, in the course of various minimally invasive surgeries, it is necessary to close multiple parts of the lumen tissue, so the current single-shot clip applier needs to be installed several times and repeatedly enters and exits the human surgical cavity to perform the closing operation of the clip. , its frequent installation of closing clips and its use in and out of the human body cavity increases the risk of surgi...

Problems solved by technology

However, in the course of various minimally invasive surgeries, it is necessary to close multiple parts of the lumen tissue, so the current single-shot clip applier needs to be installed several times and repeatedly enters and exits the human surgical cavity to perform the closing operation of the clip. , its frequent installation of closing clips and its use in and out of the human body cavity increases the risk of surgical infection for patients, increases the operation time and the probability of bleeding and leakage of the lumen tissue, and also makes the medical staff more difficult in the installation, use, cleaning and maintenance of equipment. greatly increased
