Description

technical field

[0001] The invention relates to a laparoscopic operation puncture device capable of automatic alarming and belongs to the technical field of medical instruments. Background technique

[0002] With the further development of minimally invasive surgery, laparoscopic surgery technology has become more mature, and the operation skills of surgeons have become more proficient.

[0003] However, whether it is a general surgery doctor or a gynecologist, they must perform the same operation before performing laparoscopic surgery, that is, abdominal wall puncture. Only after successful puncture, laparoscopic surgery can proceed normally.

[0004] The first step of abdominal wall puncture is blind puncture, which is also the difficulty of abdominal wall puncture. The existing abdominal wall puncture device, the Veress needle, does not have the function of prompting the puncturer whether the puncture is successful. For experienced surgical operators, the success of th...
