Abstract

A surgical apparatus includes an end effector having an ultrasonic blade, a clamp arm, and a clamp pad. The end effector applies ultrasonic energy at the blade. The clamp arm pivots relative to the blade. The clamp pad is positioned on the clamp arm adjacent to the blade. The clamp arm includes a latching feature to retain the clamp pad relative to the clamp arm to prevent the clamp pad from moving laterally, longitudinally, and perpendicularly relative to the clamp arm.
