More Information
Summary:An ultrasonic surgical instrument is disclosed including an end effector, a shaft assembly extending proximally from the end effector, and a housing extending proximally from the shaft assembly. The end effector includes a clamp arm assembly pivotable between an open position and a closed position. The clamp arm assembly includes a clamp arm including a slot, a tissue pad secured to the clamp arm, and a tab. The tissue pad includes a flange positioned in the slot. The tissue pad extends proximally to a proximal end. The tab is positioned to engage the proximal end to stop proximal displacement of the tissue pad relative to the clamp arm. Relative movement between an outer tube and an inner tube is configured to pivot the clamp arm assembly. Actuation of a trigger is configured to effect relative movement between the inner tube and the outer tube.
