Abstract
A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces, and a second jaw member positioned including an ultrasonic blade body and defining at least one electrically-conductive tissue-contacting surface. 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. The second jaw member is movable relative to the first jaw member between a first configuration, to facilitate transmission of ultrasonic energy to tissue grasped between the first and second jaw members, and a second configuration, to facilitate conduction of electrosurgical energy through tissue grasped between the first and second jaw members.
