Continuous clip-discharging clamp and continuous clip-discharging device

Abstract

The invention discloses a continuous clip-discharging clamp and a continuous clip-discharging device, and relates to the technical field of special instruments for laparoscopic surgery. The continuousclip-discharging clamp comprises a cannular clamp cavity, and a magazine installed in the camp cavity and used for installing ligating clips. One end of the clamp cavity is provided with a clamp mouth used for assisting the discharge of the ligating clips. The magazine bears against the clamp mouth. A push rod is inserted in one end, away from the clamp mouth, of the clamp cavity. The push rod ispositioned at the end part in the clamp cavity and bears against the nearest ligating clip. One end, away from the clamp mouth, of the clamp cavity is further provided with a push part capable of continuously pushing the push rod to be moved to the direction of the clamp mouth. The continuous clip-discharging clamp is capable of safely, efficiently, rapidly and continuously discharging the ligating clips. The continuous clip-discharging device is capable of continuously discharging the ligating clips with double-layer structures.

Description

technical field [0001] The invention relates to the field of special instruments for laparoscopic surgery, in particular to a continuous clip applier and a continuous clip applier. Background technique [0002] In laparoscopic surgery, doctors often use hemostatic ligation clips to ligate the tubular tissues in the human body to prevent fluid leakage in the tubular tissues, which will affect the doctor's operation and even threaten the safety of the patient. Domestic hemostatic ligation clips are divided into two categories according to materials: one is metal clips, and the other is polymer clips. Wherein the macromolecule clip can be divided into two classes again according to the structure: a class is the ligation clip of V-shaped structure, and another kind is the hemostatic ligation clip of double-layer structure (such as a kind of absorbable hemostatic ligation clip disclosed by the invention patent of publication number CN101081310A ). The instruments used to apply ...

AI Technical Summary

Problems solved by technology

Domestic clip appliers used for metal clips and V-shaped ligature clips have realized the continuous firing function, but the clip appliers used for applying double-layer structure ligation clips cannot realize the continuous firing function. ligation clip
