US 2003/0114874 A1 · Ultrasonic clamp coagulator apparatus having an improved clamping end-effector

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. The clamp arm is provided with a clamp tissue pad that has at least one raised portion to achieve the desired cutting and coagulation effect on the tissue.
