1. A surgical instrument, comprising:
an end effector assembly, including:
a first jaw member, including:
an insulative tissue-contacting surface; and
first and second electrically-conductive tissue-contacting surfaces disposed on either side of the insulative tissue-contacting surface, the first and second electrically-conductive tissue-contacting surfaces adapted to connect to a source of electrosurgical energy; and
a second jaw member, including:
an ultrasonic blade body adapted to receive ultrasonic energy from an ultrasonic transducer and positioned to oppose the insulative tissue-contacting surface of the first jaw member; and
first and second electrically-conductive tissue-contacting surfaces adapted to connect to the source of electrosurgical energy, disposed on either side of the ultrasonic blade body, and positioned to oppose the first and second electrically-conductive tissue-contacting surfaces, respectively, of the first jaw member,
wherein the first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween, and
wherein the first and second electrically-conductive tissue-contacting surfaces of the second jaw member are movable, independent of the movement of the first jaw member, relative to the first jaw member and the ultrasonic blade body between a retracted position and an extended position.
