ABSTRACT:
Surgical apparatus includes bipolar electrodes and tissue-shearing blades configured to electrically contact tissue for electrocauterization thereof prior to shearing contact of the cutting blades with the tissue over wide angles of presentation of the tissue to the electrodes and blades. Extensions or protrusions disposed along facing edges of the electrodes separate the level at which tissue is electrically contacted by the electrodes from the level at which tissue is sheared by the cutting blades.
