Abstract
An ultrasonic surgical handpiece has a motor having a torsional transducer assembly along a central axis of the surgical handpiece, the motor being configured for operative connection to a power source. A surgical attachment has a proximal end detachably connected to the motor and a distal end defining a working plane for engagement with biological tissue. The motor is configured to create a standing wave along the central axis in response to the application of an electrical current and voltage from the power source. The standing wave defines an alternating pattern of nodes and anti-nodes along the central axis, wherein a position of one of the anti-nodes along the center axis corresponds with the position of the working plane.
