    Abstract: A surgical instrument comprising an end effector including a proximal end, a distal end, a first jaw, and a second jaw is disclosed. The first jaw comprises a first electrode. The second jaw comprises a second electrode and a monopolar electrode centrally disposed down a length of the end effector. The first electrode and the second electrode cooperate to deliver bipolar energy to the tissue in a bipolar cycle. The monopolar electrode comprises a wedge shape that graduates in width along the length of the end effector. The monopolar electrode is electrically isolated from the first and second electrodes. The monopolar electrode is configured to employ monopolar energy to cut the tissue in a monopolar cycle.

    Abstract: An apparatus for operating on tissue comprises a shaft, an acoustic waveguide, and an end effector. The acoustic waveguide extends along the shaft and is configured to transmit ultrasonic vibration. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The clamp arm is pivotable toward the ultrasonic blade. The end effector defines a first longitudinal region and a second longitudinal region. The end effector is configured to clamp tissue between the clamp arm and the ultrasonic blade in the first longitudinal region. The end effector is configured to sever tissue with the ultrasonic blade in the second longitudinal region.
