Abstract: A locking device for a protective sleeve of an endoscopic electrode assembly having a connector for connecting the electrode assembly to a control handle, wherein the locking device comprises a post extending longitudinally from the connector and surrounding the elongated electrode, and a sleeve grip connected to the proximal end of the protective sleeve, surrounding the post. The sleeve grip has an unlocked position wherein the sleeve grip is movable longitudinally with respect to the post and a locked position wherein the sleeve grip is restricted from moving longitudinally with respect to the post.

Abstract: An electrosurgical device provides the electrical energy from an electrosurgical generator to an electrode for cutting, coagulation, and the like, and further provides suction and irrigation to a cannula for the electrode. The device comprises a handle assembly adapted to be held in the hand of a user. The handle assembly is connected to suction and irrigation supplies as well as to the electrosurgical generator. An instrument port at the distal end of the handle assembly has a finger wheel for rotating the instrument port in relation to the handle assembly. Cutting and coagulation current are controlled by thumb switches located on the proximal side of the handle assembly. Suction and irrigation are controlled by thumb actuated buttons also located on this proximal side. A safety switch disconnects the cutting or coagulation current from the instrument port when either the suction or the irrigation button is actuated.
