Abstract: There is a disclosed a cleaning for a medical instrument, including a nozzle main body detachably to a surgical ultrasonic treatment instrument including a channel, and the nozzle main body includes a water supply port opened in a position connected to the channel, when mounted in the surgical ultrasonic treatment instrument.

Abstract: An ultrasonic treatment apparatus of the invention is provided with an improved cleaning ability and easy recyclability. A grasping member (1720) includes a first element (1721) molded of a heat resistant resin, and a second element (1722) located inside the first element (1721) as a reinforcement in such a manner that the first element (1721) covers the outer surface of the second element (1722) entirely.

Abstract: An ultrasonic calculus treatment apparatus includes a longitudinal-vibration piezoelectric oscillator for vibrating in the axial direction of an ultrasonic transmitting member and a torsional-vibration piezoelectric oscillator for vibrating about the axial direction, and further includes driving circuits for driving the piezoelectric oscillators at respective resonance frequencies and a mode selection switch for permitting the oscillators to vibrate independently or in combination, so that lithotripsy can be performed effectively in accordance with the size of a calculus or a function of an operating tool.
