Title: System and method for tuning and controlling an ultrasonic handpiece
Inventor: BOUKHNY MIKHAIL
IPC: A61B18/00
Filed: 1997-09-09
Granted: 2000-05-11
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.
