Protective cover type invisible endoscope passage for celiac minimally invasive surgery

Abstract

The invention relates to a protective cover type invisible endoscope passage for a celiac minimally invasive surgery. The passage comprises two parts, namely an in-vitro combination platform and an in-vivo expansion cover, and is characterized in that: the in-vitro combination platform consists of a porous platform (19), a pair of combined outer ferrules (16), and an inner ferrule (17) which is arranged in the outer ferrules; the porous platform (19) is inserted into the inner ferrule; a plurality of tubular passages (18) are formed on the porous platform (19); the in-vivo expansion cover comprises a celiac passage tube (13) and a straight ball-shaped cover (20); an annular ball (12) is arranged at the bottom of the outer ring of the celiac passage tube (13) and communicated with an external air source through an inflating tube (14) which is arranged in the celiac passage tube (13) and communicated with the cavity of the annular ball (12); and the straight ball-shaped cover (20) is one with small top and large bottom and fixedly connected with the annular ball (12) into a whole.

Description

technical field [0001] The invention relates to an auxiliary instrument for abdominal surgery, in particular to a 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. It is a surgic...

Problems solved by technology

[0004] However, the currently customary minimally invasive surgery through the small abdominal incision-shaped abdominal tunnel has some obvious defects: after the small incision is opened, due to the intra-abdominal pressure, the internal organs will be squeezed towards the mouth of the cavity, which will cause Accidental injury to non-diseased tissues and organs by surgical instruments

Although at present there are also abdominal tunnels used to prevent these phenomena, but because the abdominal tunnels currently used are too simple, not only cannot be firmly positioned in small incisions under the action of human abdominal muscles, but also cannot adapt to multiple tunnels. , Requirements for simultaneous operation of multiple devices
