Abstract

In a bipolar coagulation and cutting device for endoscopic surgery with a proximal operating part and a distal grasping part interconnected by a shaft, the distal grasping part includes jaws, each having two spaced branches supported on flexible wires. The jaws are held apart but are movable toward each other by actuating means extending along the shaft for the engagement of tissue between the jaws. HF energy can be supplied for the coagulation of the tissue engaged between the jaws. A wire electrode is also mounted on the shaft so as to be movable by the actuating means between the spaced branches of the jaws for cutting, by HF energy application, the coagulated tissue engaged between the jaws.
