Abstract
A cordless ultrasonic scaler includes a cleaning tip, an actuator, power supply, control circuitry, a water reservoir and a pumping mechanism within the hand piece. A piezoelectric stack actuator drives both the cleaning tip and pumping mechanism. The reservoir in the hand piece supplies liquid to the pump for cooling the actuator, the cleaning tip and the teeth being cleaned. The reservoir defines a battery compartment. A pair of electrodes enable recharging the battery in a docking station when the device is not in use. Controls are provided for the actuator and fluid flow.
