Abstract
In a bipolar surgical shears, pivoted cutting members serve as a first electrode, and separate conductors, mounted on the cutting members and insulated therefrom, serve as second and third electrodes. One of the second and third electrodes is connected to a terminal on the opposite cutting member through a pivot pin comprising an insulating tube, so that all power supply connections are mounted on one of the pivoted cutting members. A power supply can be switched selectably to a selected one, or both, of the second and third electrodes.
