    摘要： A surgical instrument includes an end effector, and a shaft assembly. The end effector includes an ultrasonic blade, a rotating body, and a clamp arm movable between an open and a closed position. The shaft assembly extends along an axis and includes clamp arm clocking assembly and a clamp arm pivot assembly. The clamp arm clocking assembly can drive the rotating body and the clamp arm between a first clocked position and a second clocked position. The clamp arm pivot assembly includes an actuator body defining a track, where the actuator body can actuate to drive the clamp arm between the open position and the closed position while the actuator body is in a rotational position relative to the ultrasonic blade. The track houses a portion of the clamp arm in the first clocked position and the second clocked position while the actuator body is in the rotational position.

    摘要： An instrument includes an ultrasonic blade, a first fluid port, an irrigation member, a second fluid port, and a fluid communication assembly. The ultrasonic blade defines a distal opening. The ultrasonic blade is operable in a first mode to emulsify tissue that is distally positioned relative to the ultrasonic blade. The ultrasonic blade is further operable in a second mode to transect and seal tissue that is transversely positioned relative to the ultrasonic blade. The first fluid port is in communication with the distal opening of the ultrasonic blade. The irrigation member is positioned adjacent to the distal end of the ultrasonic blade. The second fluid port is in communication with the irrigation member. The fluid communication assembly is configured to couple the first fluid port with a fluid source, couple the first fluid port with a suction source, and couple the second fluid port with the fluid source.

    摘要： A surgical instrument includes an end effector, a shaft assembly, and an axial location feature. The end effector includes an ultrasonic blade and a clamp arm that can move between an open and closed position. The shaft assembly includes a proximal shaft portion, an acoustic waveguide extending proximally from the ultrasonic blade, a distal shaft portion extending along a distal axis, and an articulation section interposed between the proximal shaft portion and the distal shaft portion. The articulation section can deflect the distal shaft portion and the end effector relative to the longitudinal axis between a non-deflected position and a deflected position. The axial location feature can inhibit the ultrasonic blade from shifting relative to the clamp arm along the distal axis as the end effector is driven between the non-deflected position and the deflected position.
