Abstract
An ultrasonic instrument including a stack of laminations for converting electrical energy into mechanical vibratory energy to which is connected at one end an acoustic impedance transformer for converting the vibratory energy into longitudinal movement, with a work tip being connected to the free end of the transformer and a transition region of decreasing cross-sectional area extending between the transformer free end and the work tip. A shield is provided to divert the energy radiated from the transition region away from the work tip.
