Control system for a phacoemulsification handpiece |
摘要 |
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.
