1. A surgical dissector, comprising:
a first jaw member, comprising:
a proximal end;
a distal end;
a first tissue contacting surface;
a second tissue contacting surface;
a metallic core, wherein said metallic core of said first jaw member is configured to transmit electrosurgical energy; and
a nonmetallic layer disposed over at least a portion of said metallic core of said first jaw member, wherein said metallic core of said first jaw member is recessed relative to said nonmetallic layer of said first jaw member, and wherein said metallic core of said first jaw member is configured to contact tissue through a tissue-receiving recess defined in said nonmetallic layer of said first jaw member;
a second jaw member, comprising:
a proximal end;
a distal end;
a first tissue contacting surface;
a second tissue contacting surface;
a metallic core, wherein said metallic core of said second jaw member is configured to transmit electrosurgical energy; and
a nonmetallic layer disposed over at least a portion of said metallic core of said second jaw member, wherein said metallic core of said second jaw member is recessed relative to said nonmetallic layer of said second jaw member, and wherein said metallic core of said second jaw member is configured to contact tissue through a tissue-receiving recess defined in said nonmetallic layer of said second jaw member; and
a joint, wherein said first jaw member and said second jaw member are rotatable about said joint between closed and open positions, wherein said first jaw member and said second jaw member are configured to separate tissue by applying:
a mechanical force to the tissue upon opening said first jaw member and said second jaw member from a said closed position to a said open position; and
an electrosurgical force to the tissue.
