Abstract
An ultrasonic tool is disclosed with a handpiece () containing coils (A-D;A-D;A-B) that produce an electromagnetic field that vibrates a magnetic rod (A,B,) of a moveable pin transducer (MPT)disposed within the handpiece. Ultrasonic vibrations are produced when the coils are selectively powered by an ultrasonic signal generator, which can include a stepper motor control apparatus (). A tipcan be removably attached to an MPTA channel (A,B) in the magnetic rod (A,B) can allow fluidic communication with a handpiece fluid supply channel (). A method of vibrating a tool can include controllably energizing at least one electromagnetic coil contained within a handpiece to vibrate a magnetic rod and an attached tip. The method can include varying the energy to at least one of the electromagnetic coils with a stepper motor control apparatus.
