Invisible endoscopic channel for multichannel flexible single-hole abdominal cavity minimally invasive surgery

Abstract

The invention relates to an invisible endoscopic channel for multichannel flexible single-hole abdominal cavity minimally invasive surgery, which comprises a multihole operating platform (3) which is arranged at the outer part of the abdominal cavity, and a flexible abdominal cavity channel tube (8) which is connected with the multihole operating platform and can be inserted into the abdominal cavity, and is characterized in that: a plurality of surgical instrument channels (1) with different heights are arranged on the multihole operating platform (3). At least one intake tube (2) and an air outlet tube (3) are arranged on the multihole operating platform (3). The integral shape of the flexible abdominal cavity channel tube (8) is a section of a flexible film channel which is similar to round, the upper end of the flexible abdominal cavity channel tube (8) is connected with the multihole operating platform (3), and the lower end of the flexible abdominal cavity channel tube (8) is connected with a round turning ring (7); and an inner race (6) with a pull band (5) is arranged at the outer part of an abdominal cavity channel tube which is formed by a flexible film, and can freely shift up and down.

Description

technical field [0001] The invention relates to an auxiliary instrument for abdominal surgery, in particular to a multi-channel flexible single-hole 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. Some hospitals at home and abroad use single-port or multi-port laparoscopy to perform transumbilical single-port cholecystectomy, appendectomy, intrahepatic bile duct cystadenoma resection and so on. During the operation, these small incisions made in different parts of the abdomen with a diameter of 5-12 mm must be placed with an abdominal tunnel to facilitate the insertion of camera lenses and various special surgical instruments. The abdominal cavity captured by the camera inserted into the abdominal cavity The images of various internal organs are transmitted to the TV scre...

Problems solved by technology

Although this patented product has its own characteristics, in the actual trial process of clinicians, there is still a long distance from the requirement of obtaining greater operational freedom, that is, the requirement of a greater distance from the incision.

[0004] The multiple surgical instrument channels in the existing invention have the same height. During use, the top ends of the multiple surgical instrument channels collide and interfere with each other, thus limiting the degree of freedom of rotation
