Abstract

The invention relates to a novel hemostatic clip pushing and closing device. The novel hemostatic clip pushing and closing device comprises a handle (1) and a forceps rod (6), wherein a biological clip box (9) is arranged in the forceps rod (6). The novel hemostatic clip pushing and closing device is characterized in that the biological clip box (9) comprises a box body (901), a biological clip push head (902) and a biological clip push spring (903); a plurality of biological clips (10) are arranged at the opening end of the box body (901); a convex block structure (905) is arranged on the biological clip push head (902) and is inserted into a guide groove (904); an upper forceps jaw (7) and a lower forceps jaw (8) are provided with biological clip positioning grooves; a transmission mechanism is arranged in the forceps rod (6), and is respectively matched with the biological clip box (9) and a biological clip pushing device (3); a biological clip pushing sheet (301) at the front end of the biological clip pushing device (3) is abutted against a pushing mechanism (1001) on each biological clip (10). The novel hemostatic clip pushing and closing device has the advantages that a blood vessel is continuously, controllably and stably clamped and closed, and the clinical requirement is met.

Description

technical field [0001] The invention relates to a minimally invasive medical device for blood vessel clamping in minimally invasive surgery, in particular to a reusable and misuse-proof medical biological clip with continuous clip applicator, specifically a biological clamp with It is a medical continuous clip applicator that can semi-automatically fill and fire continuously. Background technique [0002] During endoscopic surgery, blood vessels need to be clamped to prevent bleeding when organs and tissues are severed. At present, two kinds of clip appliers are mainly used to solve the problem of blood vessel clipping. One is the reusable medical biological clip single-shot clip applier. Although this type of clip applier can effectively solve the problem of vascular ligation in endoscopic surgery, the doctor needs to remove the clip applier from the Take it out from the human body and hand it over to the nurse. The nurse puts a new hemostatic clip into the jaws of the fo...
