Abstract
Apparatus for the surgical removal of tissue is disclosed comprising a handpiece having a resonant vibrator with a magnetostrictive stack and connecting body encompassing a hollow elongated tool which is ultrasonically vibrated at its tip longitudinally to a peak to peak stroke of at least 0.005 inches at about 25,000 cps (25 KHz). A generator powers the vibrator and is automatically controlled at the frequency to maintain the resonant vibration. Aspiration is provided by suction through the hollow tool at its tip, and a manifold enclosing the tool end of the handpiece provides irrigation.
