DENTAL ULTRASONIC WORKING DEVICE

摘要

PURPOSE: To provide a dental ultrasonic working device with which a working environment is improved, the cast article of a tooth mark is prevented from being deformed and work efficiency in the fields of technical hands and treatment or the like by effectively utilizing ultrasonic energy for both the technical hand field and the treatment field. CONSTITUTION: A hand piece assembly 1 housing an ultrasonic vibrator part 2 for outputting ultrasonic waves at a prescribed frequency and a horn part 3 connected to the ultrasonic vibrator part 2 is formed, plural kinds of ultrasonic tools 5... to be selectively used corresponding to purposes while being freely attachably and detachably mounted to the hand piece assembly 1 are installed, and the parts of these plural respective ultrasonic tools 5... connected to the horn part 3 are respectively equally constituted. Further, a driving circuit for driving the ultrasonic vibrator part 2 is provided with a variable output setting means for variably setting the output level of an exciting signal.
