摘要： The invention relates to a method and apparatus for cleaning and refurbishing the adjacent planar surfaces of a pair of interchangeable surgical acoustic members. The device includes a spaced pair of outwardly biased abrasive members mounted on a rotatable housing so that the tool can be located between the adjacent planar faces and about a threaded connection between them. Rotation of the device causes the abrasive members in contact with the opposed planar surfaces to clean and refurbish those surfaces. The method of using the device is also disclosed. The device is provided as a component of a maintenance kit for the acoustic members. The kit also includes a wire brush for cleaning the threaded joint, non-shredding swabs for wiping the threads and acoustic joint, and a brush for cleaning the bores of the acoustic member.

摘要： 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.
