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.

Cleaning device for medical instruments

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

Ultrasonic treatment apparatus

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.
