Claim 0:
1. An electrosurgical instrument comprising forceps having:
a first arm including an inner tissue-engaging surface, an outer spine surface, a plurality of side surfaces extending between the inner tissue-engaging surface and the outer spine surface, a first electrode located on the inner tissue-engaging surface, and a first electrode extension portion extending from the first electrode to the outer spine surface, the first electrode and the first electrode extension portion together forming a T-shaped electrode in the first arm; and
a second arm opposing the first arm, the second arm including an inner tissue-engaging surface that faces the inner tissue-engaging surface of the first arm, an outer surface, a plurality of side surfaces extending between the inner-tissue engaging surface and the outer surface, and a second electrode located on the inner tissue-engaging surface;
wherein the first electrode extension portion passes energy in a monopolar mode from the outer spine surface of the first arm when the first arm and the second arm are in a fully closed position and the first and second electrodes are in electrical contact with one another, and the first and second electrodes pass energy in a bipolar mode from the inner tissue-engaging surfaces of the first and second arms, respectively, when the first arm and the second arm are in a partially closed position with tissue grasped therebetween.
