Abstract: An ultrasound treatment appliance comprising a surgical handpiece, an ultrasound insert, and an ultrasound generator, the handpiece including a piezoelectric transducer connected to the ultrasound insert and a piezoelectric motor connected to the ultrasound generator. The piezoelectric motor transmits ultrasound waves to the insert, which waves are defined as a function of current and voltage setpoint signals delivered by the ultrasound generator to the piezoelectric motor. The appliance also includes a module for controlling the amplitudes of the setpoint signals and configured to increase or decrease the amplitudes of the current and voltage setpoint signals when the variation in the impedance of the ultrasound signal is greater than a predetermined impedance variation value and when the variation in the frequency of the ultrasound signal is greater than or less than the predetermined frequency variation value.
