Single-channel elastic sheath and puncture releaser for laparoscopic surgery

Abstract

The invention provides a set of a single-channel elastic sheath for laparoscopic surgery and a puncturing releaser thereof, and belongs to the technical field of medical apparatus and instruments. Thesingle-channel elastic sheath is a short pipe manufactured by high-elasticity flexible materials, the wall of the single-channel elastic sheath is thick, ear handles are arranged at the tail end of the single-channel elastic sheath, the entirety is exquisite, and the compliance is good; the single-channel elastic sheath can be safely, precisely and conveniently arranged at port-site on abdominalwall through operation of the puncturing releaser to be used as a laparoscopic surgery channel, the space between sheaths can be shortened, and various operation such as in and out, traction and swinging of surgical instruments can be met; and unreliable conditions of slippage, displacement, air leakage and falling-over of a traditional Trocar and mutual occupying and collision of the sheaths areavoided, and the scientificity and minimal invasion of the laparoscopic surgery are improved. The single-channel elastic sheath of laparoscopic surgery and the puncturing releaser thereof are suitablefor various pneumoperitoneum pressure and abdominal wall conditions including infants, and particularly can meet the requirements of surgery of umbilical opening endoscope, armpit endoscope and ultra-minimally invasive endoscope establishing multiple operation channels in micro areas.

Description

technical field [0001] The invention relates to a single-channel elastic sheath used in laparoscopic surgery and a puncture releaser thereof, belonging to the technical field of medical instruments. Background technique [0002] Laparoscopic surgery significantly reduces the incision on the abdominal wall and is known as minimally invasive surgery with fast postoperative recovery. The iconic instrument of laparoscopic surgery is the Trocar (trocar or abdominal wall puncture device), which is composed of a cannula, a puncture inner core and an air valve. . The cannula is a long hard tube and has no stretchability. The grip between the incision and the abdominal wall depends on the size of the incision and the thickness of the abdominal wall. In actual operation, especially in patients with weak abdominal wall (such as infants), unreliable situations such as Trocar slippage, displacement, air leakage, and lodging often occur, which hinder the operation process. An overly la...

Problems solved by technology

An overly large air valve is also difficult to meet the ultra-micro-innovative development requirements of laparoscopic surgery to single-site multi-channel laparoscopic surgery through the umbilical cord, and it is difficult to meet the new era of surgery and medical treatment that can cure diseases and be beautiful without visible knife marks after surgery. need
