Description

Auxiliary suction device for endoscope scissors and endoscope scissors assembly

Technical Field

The utility model belongs to the technical field of auxiliary devices of endoscope scissors, and particularly relates to an auxiliary suction device for endoscope scissors and an endoscope scissors assembly formed by combining the auxiliary suction device and the auxiliary suction device.

Background

Laparoscopic surgery is a newly developed minimally invasive procedure, and is currently widely performed. Along with the rapid progress of industrial manufacturing technology, the fusion of relevant disciplines lays a firm foundation for developing new technologies and new methods, and doctors are more and more skilled to operate, so that a plurality of past open operations are replaced by intracavity operations at present, and the operation selection opportunities are greatly increased.

In the laparoscopic surgery, especially in the laparoscopic renal partial excision surgery, partial venous and even arteriole bleeding still occurs on the wound surface in the process of eliminating kidney tumors after the blockage of the renal arteries, which affects the surgical field. In the process, a doctor of the main knife holds the separating forceps with the left hand, lifts and exposes the tumor, and the right hand holds the scissors to cut the tumor, so that the bleeding wound surface enters from the auxiliary hole to be sucked by the special suction device, or the main knife exits from one hand of the instrument and is replaced by the suction device to enter, but the operation progress can be affected to a certain extent. However, after the blockage, the nephrectomy generally requires that the excision suture of the tumor is completed within 40 minutes, otherwise, the effect on the renal function is large, and the wound surface aspiration operation is continuously performed in the operation process, so that the operation progress is inevitably delayed.
