ABSTRACT:
Endoscopic surgical instruments are provided that have detachable working ends for use with a reusable handle portion. The detachable working end includes bipolar electrodes on opposing movable members for passing a high frequency current through tissue for simultaneously severing or manipulating the tissue and causing hemostasis of the tissue. An electrically insulating material is interposed between the movable members so that the electrodes are spaced apart from 0.002 to 0.050 inches and the current passes between the opposing electrodes through the tissue.
