Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to a lower snare electric cutter for a choledochoscope.
Background
The high-frequency electric knife pen has the advantages of rapid hemostasis, less bleeding, bacterial infection prevention, good postoperative healing of patients and the like, so the high-frequency electric knife pen is widely applied to surgical operations and is an electronic surgical instrument capable of replacing a mechanical scalpel to cut tissues.
Because the choledochoscope is a long and narrow single-channel choledochoscope, the existing high-frequency electrotome is not suitable for cutting and hemostasis of the choledochoscope. Through continuous improvement technology, the existing tool for stopping the blood of the choledochoscope is an electrocoagulation ball, but the electrocoagulation ball only has the function of stopping the blood and cannot cut gallbladder polyps. In the choledochoscope descending gallbladder polyp excision operation, polyps can only be clamped by endoscope biopsy forceps and then stopped by an electrocoagulation ball. And after polyps are clamped by the endoscope biopsy forceps, the phenomenon that the base part is uneven or the clamping is incomplete is easily caused, and the polyps are the main factor for recurrence. How to cut and stop bleeding at one time is a problem which is urgently needed to be solved at present in the way of gallbladder polyp descending polypectomy treatment under a choledochoscope.
