Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a smoke exhaust device for laparoscopic surgery. Background Art

[0002] At present, "minimally invasive surgery" has become the main surgical method for various surgical operations, among which pneumoperitoneum laparoscopy occupies the most important position. Energy instruments in pneumoperitoneum laparoscopy are the main body of hemostasis and cutting. The smoke produced by various energy instruments such as monopolar and bipolar electrosurgical knives, PK knives, workstations, etc. will seriously affect the surgical field of view.

[0003] In existing laparoscopic surgeries, surgeons usually discharge smoke directly into the operating room, polluting the air and endangering the health of staff. In addition, in laparoscopic surgeries, a needle is used to connect to the operating room suction device, which results in an unstable connection. The length of the suction tube cannot be adjusted, which results in smoke in a part of the area during the operation not being discharged in time, and the smoke elimination rate is slow, thus affecting the efficiency of the operation.
