Abstract: A surgical end effector includes an ultrasonic blade and a jaw member. The blade is adapted to receive ultrasonic and electrosurgical energy and defines a distal face. The jaw member is movable relative to the blade from a spaced-apart to an approximated position for clamping tissue and includes a structural body having a body portion and a distal cap portion. The distal cap portion defines an electrode that receives electrosurgical energy. The jaw member further includes a jaw liner engaged within the body portion and extending therefrom towards the blade such that, in the approximated position, the jaw liner contacts the blade to define a gap distance between the electrode and the distal face to facilitate bipolar electrosurgical tissue treatment upon conduction of bipolar energy between the electrode and the distal face and through tissue in contact therewith.
