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 and a surgical instrument including the end-effector are disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and to electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw, a cantilever electrode configured to electrically couple to an opposite pole of the electrical generator. The cantilever electrode is fixed to the clamp jaw at a proximal end and free to deflect at a distal end. The clamp arm includes control features to adjust a tissue path relative to the clamp arm to create a predefined location of contact.
