Description

Puncture outfit special for laparoscopic surgery

Technical Field

The utility model relates to a medical instrument, in particular to a puncture outfit special for laparoscopic surgery.

Background

Compared with the traditional operation, the laparoscopic minimally invasive surgery has the advantages of small wound, small damage to peripheral tissues, quick recovery, obvious relief of postoperative pain of patients and the like, and is widely applied to urinary tumor surgery (such as gallbladder cancer, bile duct cancer, rectal cancer and the like). The puncture outfit for laparoscope is a minimally invasive surgical instrument, and is used for establishing an operation channel for the minimally invasive instrument to enter and exit from an abdominal cavity during an operation. The puncture outfit comprises a cannula assembly and a puncture assembly, the puncture assembly is pulled out after the puncture is successful, the minimally invasive instrument enters and exits through the cannula assembly, and the cannula assembly is pulled out until the operation is completed, and the wound is sutured. However, a gap exists between the sleeve assembly of the existing puncture outfit and the poking and clamping hole, and air and tumor cells in the abdominal cavity enter the poking and clamping hole from the gap between the sleeve and the poking and clamping hole, so that iatrogenic tumor implantation is caused, and the pain of a patient and the medical expense are increased. According to literature reports, the sticking-hole-poking tumor implantation rate after laparoscopic minimally invasive gallbladder cancer surgery is as high as 14-29%, and the sticking-hole-poking tumor implantation rate of colorectal cancer is 0.69-3.3%. Therefore, how to design a special puncture outfit capable of plugging the puncture hole and the casing gap is a relevant problem to be solved urgently by those skilled in the art.
