1. An apparatus for use as a working end of a surgical instrument, the apparatus comprising:
a paired facing first and second metal jaw members movable between open and closed positions and having corresponding first and second facing surfaces capable of receiving tissue therebetween;
a microwave energy emitter contained within each of said paired facing jaw members;
a microwave absorbing insert, made from microwave absorbing materials, disposed in each of said paired facing jaw members, each microwave absorbing insert receiving said microwave energy and providing heat therefrom, and each microwave absorbing insert being at least partially disposed between said microwave energy emitter and a corresponding one of said first and second facing surfaces of said paired jaw members, wherein
each microwave energy emitter is coupled to a microwave energy source for delivery of microwave energy to said microwave absorbing inserts to be absorbed and transferred as heat energy to said corresponding facing surfaces of said first and second paired jaw members; and
a pair of electrodes coupled to a bipolar radiofrequency (RF) energy source and each partially surrounded by a corresponding one of said microwave absorbing inserts and capable of contact with tissue received between said paired first and second metal jaw members.
