END EFFECTOR FOR INSTRUMENT WITH ULTRASONIC AND ELECTROSURGICAL FEATURES

An apparatus includes a body, a shaft assembly, and an end effector. The end effector includes an ultrasonic blade and a clamp arm assembly. The ultrasonic blade is in acoustic communication with an acoustic waveguide of the shaft assembly. The clamp arm assembly is pivotable toward and away from the ultrasonic blade. The clamp arm assembly includes a clamp pad and an electrode. The clamp pad is configured to compress tissue against the ultrasonic blade. The clamp pad has a proximal end, a distal end, and a pair of lateral sides extending from the proximal end to the distal end. The electrodeis operable to apply RF energy to tissue. The electrode extends along both lateral sides of the clamp pad. The electrode further extends around the distal end of the clamp pad. 本发明公开了种设备，该设备包括主体、轴组件和端部执行器。该端部执行器包括超声刀和夹持臂组件。超声刀与轴组件的声波导声学连通。夹持臂组件能够朝向和远离超声刀枢转。夹持臂组件包括夹持垫和电极。夹持垫被构造成能够抵靠超声刀压缩组织。夹持垫具有近侧端部、远侧端部以及从近侧端部延伸至远侧端部的对侧面。电极能够操作以向组织施加射频能量。电极沿着夹持垫的两个侧面延伸。电极还围绕夹持垫的远侧端部延伸。
