Publication number: 20150164531Abstract: An apparatus comprises a shaft assembly, an ultrasonic blade, and a clamp assembly. The shaft assembly comprises an acoustic waveguide operable to transmit ultrasonic vibrations to the blade. The clamp assembly comprises a clamp arm pivotable toward and away from the blade about a pivot axis, to clamp tissue between the clamp arm and the blade. A rotation feature may provide rotation of the blade relative to the clamp arm about the longitudinal axis of the waveguide. Alternatively, the rotation feature may provide rotation of the clamp arm relative to the blade about the longitudinal axis. The rotation feature may be driven based on pivotal positioning of the clamp arm relative to the blade about the pivot axis. The rotation feature may selectively lock and unlock the angular position of either the blade or the clamp arm about the longitudinal axis at any of a number of predetermined angular positions.Type: ApplicationFiled: December 17, 2013Publication date: June 18, 2015Inventors: Craig N.

Publication number: 20150148834Abstract: An apparatus comprises a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm comprises a clamp pad. The clamp arm is movable toward the ultrasonic blade to compress tissue between the clamp pad and the ultrasonic blade in two stages. During the first stage, the clamp arm is configured to compress tissue with only a distal portion of the clamp pad. During the second stage, the clamp arm is configured to compress tissue with the distal portion and a proximal portion of the clamp pad. Thus, the tissue compression begins at the distal portion and subsequently progresses toward the proximal portion.Type: ApplicationFiled: November 25, 2014Publication date: May 28, 2015Inventors: Jacob S.
