1. A laparoscopic ultrapolar electrosurgery device comprising:
a handpiece member having a first end, a second end, and at least one of an activation element for cutting and an activation element for coagulation;
a return electrode comprising a conductive hollow tubular member having a first end, a second end contained within the first end of the handpiece member, and a conductive appendage extending from the first end of the conductive hollow tubular member wherein the conductive appendage comprises a conductive loop having an opening therethrough and a largest width of the conductive appendage is less than a diameter of the conductive hollow tubular member;
an active electrode contained within the handpiece member and the conductive hollow tubular member wherein at least a portion of the active electrode extends beyond the first end of the conductive hollow tubular member and comprises a planar conductive member having a sharp edge; and
an actuator contained within the handpiece member and in communication with the active electrode to move the active electrode toward the conductive appendage of the return electrode when at least one of cutting and coagulation is activated.
