One-time double clamp cut-off clamp applier

Abstract

The invention discloses one-time double-clamp cutting-off clamping forceps which comprise double-clamp structures, double-chuck mechanisms, clamping transmission mechanisms, cutting-off blade and cutting-off transmission mechanisms, rotation mechanisms and fixing handle mechanisms. The one-time double-clamp cutting-off clamping forceps have the advantages that two ends, with certain lengths, of each blood vessel can be accurately fixed and can be simultaneously fastened and closed, and each blood vessel with the two fastened and closed ends can be cut off from the middle; the blood vessels can be prevented from being excessively ligatured or cut, and accordingly injury on healthy tissues of human bodies can be obviously reduced; the blood vessels are fastened and cut off by the same instrument at one step, and procedures in which a surgeon extends ligature forceps into a human body at first, fastens and close two ends of a blood vessel, takes the ligature forceps out of the human body, extends a cutting-off appliance into the human body and cuts off the blood vessel can be omitted; the surgical speeds can be obviously effectively increased, and the surgical risks can be reduced; ligature clips are plastic clips with self-locking inverted fasteners, are firm and reliable and can be prevented from falling off; the ligature clips made of recyclable materials can automatically decompose in the human bodies within 6-8 months.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a one-time double-clamp cut-off clip applicator suitable for fastening, closing and cutting blood vessels in human surgery and minimally invasive surgery. Background technique [0002] For a long time, there are two kinds of medical devices for vascular ligation in the international and domestic markets, one is a reusable single-shot absorbable ligation clip applier. 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 applicator with a single biolo...
