A laparoscopic clip applier for ligation clips

Abstract

A laparoscopic clip applier for a ligature clip comprises a fixed handle, a movable handle, an operating casing and an operating rod. The first end of the operating rod is connected with a pair of clamping heads used for closing the ligature clip, and the second end of the same is elastically operated to move back and forth through the movable handle; the fixed handle is integrally welded to the fixed casing, the movable handle is hinged to a slot of the fixed handle, an action end of the movable handle can extend into the fixed casing through an opening formed in the fixed casing, and the movable handle can enable the operating rod to move back and forth along the length direction of the operating rod by allowing the action end to operate an operating-rod sleeve head which is in threaded connection with the second end of the operating rod. The laparoscopic clip applier is simple in structure, few in parts, high in working reliability and easy to sterilize and disinfect.

Description

technical field [0001] The invention relates to a surgical medical instrument, in particular to a laparoscopic clip applier for closing a ligation clip during a surgical operation. The ligation clip can be clinically used for anastomosis and ligation of blood vessels and tissues during in vivo surgery. In practical applications, the ligation clip is also commonly called a blood vessel clip, a ligation buckle, a surgical lock clip, a tissue clip, and the like. Background technique [0002] In order to fully expose the surgical field of view during the surgical operation, it is necessary to ligate the broken blood vessels in the incision to prevent bleeding. Hemostasis technology has become one of the cores of basic surgical techniques, and surgical operations on any part of the human body almost without exception involve bleeding and hemostasis. Generally, the broken blood vessel is clamped with hemostatic forceps and then ligated with sutures. This method is cumbersome to o...

AI Technical Summary

Problems solved by technology

This kind of clip applier has a simple structure, but the hand operation range is large, and it is difficult to disengage when two fingers pass through the ring on the clamp arm, which is inconvenient to operate.

[0005] There is also another type of clip applier, for example, WO02080783A1 discloses a clip applier that can be used in laparoscopic surgery, but not a clip applier for ligation clips, and has a particularly complicated structure, high cost and many structural parts , poor reliability and too many structural gaps are not conducive to sterilization
