Demountable type flexible abdominal cavity micro-invasive operation invisible endoscope channel

Abstract

The invention relates to a demountable type flexible abdominal cavity micro-invasive operation invisible endoscope channel which comprises a valve-comprising porous platform and a flexible abdominal cavity channel pipe, wherein the valve-comprising porous platform is placed outside the abdominal cavity, the flexible abdominal cavity channel pipe is connected with the porous platform and can be detachably inserted into the abdominal cavity, and a quick separation/coupling mechanism is arranged between the valve-comprising porous platform and the flexible abdominal cavity channel pipe capable of being inserted into the abdominal cavity; multiple one-way valves with an independent appliance channel and a group of gas inflow pipes and gas outflow pipes are arranged on the porous platform, the abdominal cavity channel pipe is a segment of sub-circular flexible thin film channel, the upper end of the abdominal cavity channel pipe is connected with the porous operating platform and the lower end of the abdominal cavity channel pipe is connected with a round overturning ring; and an inner ring, which can realize up-and-down free displacement and is provided with a lifting belt, is arranged outside the abdominal cavity channel pipe formed by the flexible thin film. The device has an airtight function, can maintain pneumoperitoneal pressure when a protection appliance enters a body, and can conveniently and quickly eliminate smog generated due to electric knife burning tissues, thereby facilitating the free apparatus operation by surgeon, shortening operation time, and bringing convenience for the surgeon in taking out the samples multiple times.

Description

technical field [0001] The invention relates to an auxiliary instrument for abdominal surgery, in particular to a detachable flexible invisible endoscope channel for minimally invasive abdominal surgery. Background technique [0002] With the development of medical technology, minimally invasive surgery using laparoscopic technology has been increasingly popularized and used in China. Today, most of the diseases in abdominal surgery can be done by laparoscopic technique. At the same time, laparoscopic technology is also developing towards fewer and more concealed wounds, and single-port transumbilical laparoscopy is currently the most promising research direction. [0003] The single-port laparoscopic technique concentrates multiple puncture ports used in laparoscopic surgery in one incision on the umbilicus, so that the postoperative scar will be hidden in the umbilical fossa, which is not easy to be found, and thus has obvious cosmetic effects. The umbilical cord is the ...
