MULTI-LAYER CLAMP ARM PAD FOR ENHANCED VERSATILITY AND PERFORMANCE OF A SURGICAL DEVICE

摘要

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.
