A surgical scissors (10) for use in endoscopic surgery allows both mechanical cutting and RF coagulation. The scissors blades (60, 62) are mounted on the distal end of an elongated rigid tube (12) dimensioned to fit through a working lumen of an endoscope or a trocar. The blades (60, 62) are a composite, including a metal blank and a ceramic layer (92, 104) adhered to the opposed blade faces. A scissors style handle (24) is coupled via a longitudinally rigid rod member (66) to the movable blade (62), causing it to pivot relative to the fixed blade (60) when the scissors-type handle (24) is manipulated. The blades (60, 62) are electrically insulated from each other along their entire lengths.
