ABSTRACT:
The invention provides an electrosurgical device (2) and method for cauterizing tissue and evacuating fluid from the surgical site. The device comprises an insulated conductive shaft (4) having a proximal end coupled to an electric generator (40) and a distal end coupled to an electrode (6) for cutting or coagulating tissue. The shaft has an inner lumen (14) fluidly coupled to a vacuum source (50) and a plurality of insulated side holes (8) in communication with the lumen. The side holes are configured to remain free of obstructions so that fluid, such as smoke, can be continuously evacuated during the surgical procedure.
