1. Main
Unit
It is the heart of the scaler. Functionally, the main unit generates the
needed 29KHz-operation-signal and passes it on to the Handpiece, and
thus induces power to vibrate the Insert inside the Handpiece accordingly.
Due to pressure variations, a signal from the Handpiece will be fed back to
the main unit so that the main unit can track the variation of the loading
and adjust the intensity of the controlling signal accordingly.
2.
Handpiece
The Handpiece consists of vibrator and a Tip. The vibrator is composed
of four pieces of piezoelectric plates. It generates displacement when
driven by the electrical signal from the Main Unit . The vibrator will
move the Tip back and forth in high speed based on the waveform change
of the controlling signal. In addition, the movement of the Tip will
induce current on the feedback circuit and the induced signal is then fed
back to the Main Unit to complete the control loop. In accordance with
the movement of the Tip, a powerful water stream (working like a
syringe) will also come out to a) wash away the tooth calculus and tartar,
and b) cool down the temperature of the Tip (heat generated from the
vibration of the Tip).
Caution:
Make sure that new Tip is fully seated.
