Abstract

The invention discloses a single-port laparoscopic surgical instrument channel, and relates to the field of medical instruments. For overcoming the defects that an existing single-port laparoscopic surgical instrument channel cannot be well fixed to an incision part, surgical specimens are inconvenient to take out, and the price is high, the invention provides the single-port laparoscopic surgical instrument channel which comprises an upper-layer module and a lower-layer module. The upper end of the upper-layer module is provided with a smoke outlet, a gas inlet and three or more instrument channels. The lower-layer module is provided with a gas injection hole, an upper-layer chuck and a lower-layer chuck, the gas injection hole is located in the upper-layer chuck, and the upper-layer chuck is connected with the lower-layer chuck through a hollow supporting belt; gas is injected through the gas injection hole so that the hollow supporting belt can expand, the upper-layer chuck expands, the lower face of the upper-layer chuck makes close contact with the skin, the lower-layer chuck expands, and the upper face of the lower-layer chuck makes close contact with the peritoneum. The single-port laparoscopic surgical instrument channel has the beneficial effects that the single-port laparoscopic surgical instrument channel can be well fixed at an operative incision part, a specimen can be conveniently taken out, and the price is low.

Description

technical field [0001] The invention provides a single-hole laparoscopic surgical instrument channel, which relates to the field of medical instruments. Background technique [0002] At present, with the development of medical level, patients have higher and higher requirements for the size of surgical incision. Single-port laparoscopic surgery is the most cutting-edge minimally invasive technology in the world. During the operation, surgical instruments and equipment enter the abdominal cavity through a single port. Four holes, three holes, and two holes were changed to one hole in endoscopic surgery. The existing single-hole laparoscopic surgical instrument channel cannot be well fixed at the incision site, which is not convenient for taking out the surgical specimen and is expensive. Contents of the invention [0003] In view of this, the object of the present invention is to provide a single-hole laparoscopic surgical instrument channel, comprising: an upper module an...
