1. An ultrasonic surgical instrument for use with a handpiece assembly comprising:

  • a transducer assembly adapted to vibrate at an ultrasonic frequency, the transducer assembly rotatable with respect to the handpiece assembly while vibrating at the ultrasonic frequency;

    a mounting device having a first end and a second end, the mounting device adapted to receive ultrasonic vibration from the transducer assembly and to propagate the ultrasonic vibration from the first end to the second end of the mounting device, the first end of the mounting device being coupled to the transducer assembly the mounting device being adapted to rotate on one end of the handpiece assembly;

    a transmission rod having a first end and a second end, the transmission rod adapted to receive ultrasonic vibration from the transducer assembly and to propagate the ultrasonic vibration from the first end to the second end of the transmission rod, the first end of the transmission rod being coupled to the second end of the mounting device; and

    an end effector having a first end and a second end, the end effector adapted to receive the ultrasonic vibration from the transmission rod and propagate the ultrasonic vibration from the first end to the second end of the end effector, the first end of the end effector coupled to the second end of the transmission rod.
