    摘要: A surgical instrument end effector assembly includes a first jaw member and a second jaw member. The second jaw member includes an ultrasonic blade body and first and second electrodes disposed on either side of the ultrasonic blade body and extending longitudinally along a majority of a length of the ultrasonic blade body. The ultrasonic blade body is adapted to receive ultrasonic energy from an ultrasonic waveguide. The first and second electrodes taper in width proximally to distally and are adapted to connect to a source of electrosurgical energy. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween.

    摘要: An ultrasonic surgical instrument includes a transducer assembly having a distal engagement member and configured to supply ultrasonic energy. A waveguide defines a longitudinal axis and has a proximal engagement member configured to threadingly engage the distal engagement member. The waveguide is configured to transmit the ultrasonic energy therealong to a distal end thereof for treating tissue. A torque member is coupled to the transducer assembly and is disposed about the longitudinal axis. The torque member is selectively rotatable about the longitudinal axis and relative to the waveguide to threadingly engage the transducer assembly and the waveguide to one another. The torque member includes a plurality of fingers pivotably coupled thereto and movable between a closed position and an open position. In the open position, each finger extends substantially perpendicularly from the longitudinal axis to define a moment arm that facilitates the engagement of the transducer assembly and the waveguide.

    摘要: A method of treating tissue includes ultrasonically treating tissue by oscillating a blade of an ultrasonic surgical instrument in contact with tissue and activating a fluid control system to pump cooling fluid through a blade conduit of the blade to cool the blade.

    摘要: A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces, and a second jaw member positioned including an ultrasonic blade body and defining at least one electrically-conductive tissue-contacting surface. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween. The second jaw member is movable relative to the first jaw member between a first configuration, to facilitate transmission of ultrasonic energy to tissue grasped between the first and second jaw members, and a second configuration, to facilitate conduction of electrosurgical energy through tissue grasped between the first and second jaw members.
