Ultrasonic treatment apparatus for performing medical treatment by use of ultrasonic vibrations

摘要

A medical treatment apparatus utilizing ultrasonic vibrations includes an ultrasonic vibration generator having an ultrasonic oscillator with a first through-hole formed therein. A liquid supply device is communicated with one end of the first through-hole, and a second through-hole of a horn mounted on the ultrasonic vibration generator is communicated with the other end of the first through-hole. A transmission member for transmitting ultrasonic vibrations is connected to a front portion of the horn, and a tube member is arranged to surround the transmission member. A passage formed between the tube and transmission members is coupled to the second through-hole by coupling members, and the transmission member is slightly protruded from the distal end of the tube member. Therefore, a sufficient amount of the liquid supplied from the liquid supply device can be flowed through the passage.
