摘要：
A lithotripter is provided for fragmenting a stone inside a patient's body. In one form, the lithotripter includes a motor having at least two modes of operation and is configured to produce first and second waveforms. A wave guide shaft is configured to transmit the first and second waveforms to the stone. In one form, at least one of the first and second waveforms is provided to the stone at a frequency that is about equal to a natural frequency of the stone. In a variation, the lithotripter may include an ultrasonic driver configured to produce an ultrasonic frequency waveform and a sonic driver configured to produce a sonic frequency waveform. The sonic driver is mechanically coupled to the ultrasonic driver. The ultrasonic driver and the sonic driver may be disposed within a driver housing. In another variation, the lithotripter may include a brushless DC motor.
