Abstract

A surgical instrument including a housing, a transducer assembly, a motor, a hollow sheath, and a blade is disclosed. The transducer assembly may be rotatably supported within the housing and may be configured to selectively generate an ultrasonic motion. The motor may be coupled to the transducer assembly and may be configured to selectively apply rotational motion to the transducer assembly. The hollow sheath may be coupled to the housing and may define a distal cavity. The blade may be coupled to the transducer assembly and may be rotatably supported within the hollow sheath. A distal end of the blade may include a tissue-cutter that may be rotatably supported in the distal cavity. The distal cavity may comprise a friction reducing material. A portion of the tissue-cutter may be arranged to apply the ultrasonic motion to tissue.
