Spiral gradually opening protective cover type invisible endoscopic channel for celiac minimally invasive surgery

Abstract

The invention relates to a spiral gradually opening protective cover type invisible endoscopic channel for celiac minimally invasive surgery, which comprises an in-vitro combination platform and an in-vivo expanded cover, and is characterized in that: the in-vitro combination platform consists of a porous platform (21), a pair of combined outer sleeve rings (16) and an inner sleeve ring (17) arranged in the combined outer sleeve rings (16), the porous platform (21) is inserted into and connected with the inner sleeve ring, and the porous platform (21) is provided with a plurality of tubular channels (18); and the in-vivo expanded cover comprises a tubular channel component and a spiral gradually opening cover, wherein the tubular channel component consists of a celiac channel pipe (13), an inflation pipe (14) and an annular ball bag (12) which is arranged at the bottom of the external circle of the celiac channel pipe and is communicated with an outside air source through the inflation pipe that is arranged in the celiac channel pipe and communicated with the annular ball bag (12); and the spiral gradually opening cover is an annular gradually opening cover and is fixedly connected the annular ball bag (12) into a whole.

Description

technical field [0001] The invention relates to an auxiliary instrument for abdominal surgery, in particular to a spiral involute shield type 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. In laparoscopic surgery, 2-4 hole operations are often used, one of which is opened on the navel (or other parts of the abdomen) of the human body to avoid leaving long scars on the patient's abdominal cavity. After recovery, only in the abdominal cavity There are 1-3 linear scars of 0.5-1 cm left on the site, which can be said to be a small wound and less painful surgery, so some people call it "keyhole" surgery. The development of laparoscopic surgery reduces the pain of surgery for patients, shortens the recovery period of patients, and relatively reduces the expenditure of patients...

AI Technical Summary

Problems solved by technology

However, because the abdominal cavity currently used is too simple, not only can it not be reliably positioned in the small incision under the action of the abdominal muscles of the human body, but also cannot adapt to the requirements of multi-channel and multi-instrument simultaneous operation.
