Abstract

An ultrasonic surgical clamp coagulator apparatus is configured to effect cutting, coagulation, and clamping of tissue during surgical procedures. The apparatus includes an elongated portion having a pivotal clamp arm at a distal end thereof for clamping tissue against an associated ultrasonic end-effector. A clamp arm mount of the apparatus interferingly engages the pivotal clamp arm to thereby maintain the clamp arm in substantial alignment with the end-effector, while accommodating normal manufacturing tolerances of the components.
