Abstract
An ultrasonic surgical clamp coagulator apparatus is configured to effect cutting, coagulation, and clamping of tissue by cooperation of a clamping mechanism of the apparatus with an associated ultrasonic end-effector. The clamping mechanism includes a pivotal clamp arm which cooperates with the end-effector for gripping tissue therebetween. The clamp arm is preferably provided with a clamp tissue pad having a plurality of axially spaced gripping teeth which cooperate with the end-effector to achieve the desired ultrasonic effect on tissue, while facilitating grasping and gripping of tissue during surgical procedures.
