ABSTRACT:
A bipolar electrosurgical instrument for use in laparoscopic surgery or other minimally invasive internal surgical procedures is disclosed. In one embodiment, a bipolar electrosurgical apparatus (10) is provided which is suitable for laparoscopic applications. The apparatus (10) comprises an active electrode (18) and a current return electrode shoe (34). A spring (44) or other resilient member urges the shoe (34) into tissue contact when the active electrode (18) is positioned for surgery. In another embodiment, an axially retractable active electrode (90) is used to grip tissue and draw the tissue back to a passive electrode (92) The apparatus of the present invention is capable of functioning in cutting, coagulation and desiccation modes.
