Abstract: A system and method for tuning and controlling ultrasonic handpieces by varying the frequency of the drive signal that is fed to the handpiece by a discrete dither increment. A digital signal processor may be used to measure the response of the handpiece to the varying drive signal and compare these responses to determine the probable value of the actual series resonance. The output of the digital signal processor is used to generate control parameters embodied within an appropriate control signal, which is fed to the source of the drive signal in order to alter aspects of the drive signal.

Abstract: A system and method for tuning and controlling ultrasonic handpieces by incorporating a broad-spectrum signal as at least a component of the signal used to drive the handpiece. The response of the handpiece to this broad-spectrum signal is measured and the frequency or amplitude or both of the drive signal are adjusted in order to maintain the desired level of handpiece performance. The operation of the systems and the performance of the methods described enable the handpiece to be operated in a most effective manner over a more widely varying range of mechanical load and thermal conditions than was possible through the use of prior control systems and methods.

Abstract: A hand held applicator for applying ultrasound power to treat human tissue, includes a transducer (1) having excitation electrodes. A power amplifier (13) responds to an oscillating signal from a variable frequency oscillator (23) to supply electrical power to the transducer (1) via a connection to the excitation electrodes. The transducer (1) and the power amplifier (13) have a power-conversion-­efficiency characteristic that is a function of the frequency of the oscillating signal and the acoustic load on the transducer (1). The frequency of the oscillating signal is controlled by a sampler (5) having a timer for defining alternating sample and hold timing intervals and means for producing a frequency-control signal having a magnitude that varies during each sample interval and that remains essentially constant during each hold interval. The means for producing the frequency-control signal includes a peak-detector operative during each sample interval for setting the magnitude of the frequency-­control signal so that throughout the ensuing hold interval the transducer and the power amplifier operate with essentially peak-power-conversion efficiency.

Abstract: There is disclosed herein a driver system for an ultrasonic probe for allowing a user to have proportional control of the power dissipated in the probe in accordance with the position of power dissipation controls operable by the user and for automatically tuning upon user request such that the driving frequency is equal to the mechanical resonant frequency of said probe and such that the re­active component of the load impedance represented by said probe is tuned out. The system uses a tunable inductor in series with the piezoelectric crystal excitation transducer in the probe which has a flux modulation coil. The bias current through this flux modulation coil is controlled by the system. It is controlled such that the inductance of the tunable inductor cancels out the capacitive reactance of the load impedance presented by the probe when the probe is being driven by a driving signal which matches the mechanical resonance frequency of the probe. The resulting overall load impedance is substantially purely resistive. The system measures the phase angle and monitors the load current. This informa­tion is used to determine the mechanical resonance frequency by sweeping through a band of driving frequen­cies and finding the peak load current where the slope of the load current versus frequency function is greater than a predetermined constant. After the automatic tuning to the resonant frequency, the system automatically adjusts the bias current flowing through the flux modulation coil to maintain the substantially purely resistive load imped­ance for changing power levels. There is also disclosed herein an analog circuit to measure the Phase angle for the load driving signal and to adjust the frequency of the driving signal for best performance. This system includes an integrator to eliminate the effect of offset errors caused by operational amplifiers.
