Technical Field

The invention relates to the technical field of dental medical instruments, in particular to a root canal swinging and washing machine head.

Background

At present, two instruments for root canal swinging washing are available on the market, one is that an ultrasonic vibration generator in a handle generates ultrasonic vibration to drive a working tip to vibrate at high frequency; the other type is that a vibration motor in the handle rotates at a high speed to generate high-frequency vibration which is transmitted to the working tip to realize the function of vibration washing.

Because the two structures need the special vibration-generating handle matched with the working tip, the vibration is transmitted to the working tip through the vibration transmission structure, and the purpose of root canal swinging washing is realized.
