摘要：
An ultrasonic surgical instrument is disclosed. The ultrasonic surgical instrument includes a housing, an ultrasonic transducer assembly to selectively generate ultrasonic motion, a motor within the housing, an outer sheath coupled to the housing, and a blade operably coupled to the ultrasonic transducer assembly and rotatably supported within the outer sheath for rotation with the ultrasonic transducer assembly. The ultrasonic transducer assembly is rotatably supported within the housing. The motor is configured to selectively apply a rotary motion to the ultrasonic transducer assembly. The outer sheath comprises a distal tip portion defining a tip cavity. The blade includes a tissue-cutting distal end rotatably supported within the tip cavity. A portion of the tissue-cutting distal end is configured to apply the ultrasonic motion to tissue.
