Abstract
A bipolar electrosurgical scissors for use in open or endoscopic surgery has a pair of opposed metal blade members pivotally joined to one another and to the distal end of the scissors itself by a rivet. Each of the blade members comprises a cutting blade having an electrode on the non-shearing surface. An intermediate insulative coating is disposed between each cutting blade and its associated electrode coating. The cutting blade is preferably fabricated from metal such as stainless steel and the electrode coating comprises metal traces deposited thereon through a mask to yield a desired pattern extending along but separated from the blade's cutting edge. Cutting is performed, steel-on-steel, without causing a short circuit between the blades which themselves may function as one of the bipolar electrodes.
