Disclosed is a surgical instrument with an end-effector adapted and configured to deliver a plurality of energy modalities to tissue at a distal end thereof. The energy modalities may be applied simultaneously, independently, or sequentially. A generator is electrically coupled to the surgical instrument and is configured to supply a plurality of energy modalities to the end-effector. In one aspect, the generator is configured to supply electrosurgical energy (e.g., monopolar or bipolar radio frequency (RF) energy) and ultrasonic energy to the end-effector to allow the end-effector to interact with the tissue. The energy modalities may be supplied to the end-effector by a single generator or multiple generators.

Method of operating a combination ultrasonic / bipolar RF surgical device with a combination energy modality end-effector

An end-effector is disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw, a clamp arm pad, and a cantilever electrode that is free to deflect. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. Also disclosed are configurations where the clamp arm includes a peripheral cantilever electrode and a clamp arm pad extending beyond the electrode, a floating cantilever electrode and a resilient clamp arm pad, an interlocked cantilever electrode plate and a clamp arm pad configured to receive the plate, a laterally deflectable cantilever electrode and a clamp arm pad extending beyond the electrode, and a flexible cantilever electrode and a clamp arm pad extending beyond the electrode.
