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

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.
