Abstract
An ultrasonic instrument includes a tip portion, a transducer configured to convert electrical energy into vibrational energy, an acoustic transformer interconnecting the transducer and the tip portion, and a grip portion disposed at least partially about the acoustic transformer. The grip portion is coupled to the acoustic transformer via a resilient nodal coupling at a nodal region of the acoustic transformer. The resilient nodal coupling is configured to provide rotational and axial stability to the acoustic transformer.
