An end-effector configured to grasp tissue is disclosed herein. The end-effector includes an ultrasonic blade configured to transfer ultrasonic energy to the tissue and a clamp arm. The clamp arm includes a clamp arm pad including an electrically conductive material and an electrically non-conductive material. The clamp arm pad is configured as an electrode of a radiofrequency energy circuit, wherein the electrode is configured to transfer radiofrequency energy through the tissue to a return electrode of the radiofrequency energy circuit, and wherein the electrically non-conductive material is configured to reduce the possibility of an electrical short between the electrically conductive material and the ultrasonic blade as the clamp arm pad degrades throughout the usable life of the end effector.

Multi-layer clamp arm pad for enhanced versatility and performance of a surgical device

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.
