    摘要: A medical instrument includes a handpiece, an electromechanical transducer disposed in the handpiece, and an electrical circuit disposed at least partially in the handpiece for supplying alternating electrical current of a predetermined frequency to the transducer. A probe is operatively connected to the transducer for transmitting vibrations generated by the transducer to an operative site in a patient. A switching device is mounted to the handpiece and is operatively connected to the circuit and the transducer for enabling the supply of power to the transducer during a motion of the probe in a preselected direction relative to the handpiece and for disabling the supply of power to the transducer upon a termination of motion of the probe in the preselected direction.

    摘要: An ultrasonic medical treatment device has a probe, a transducer for mechanically vibrating the probe at an ultrasonic frequency, a voltage source for energizing the transducer, and another electrical voltage source for feeding to the probe a high-frequency alternating waveform of limited current and limited voltage to be conducted into a patient through the operative tip of the probe after placement of the operative tip into contact with the patient. The alternating waveform has a current and a voltage so limited as to prevent damage to organic tissues while stimulating nerves to reduce or suppress pain.

    摘要: An electrical waveform generator for driving an electromechanical load includes a digital signal processor connected to a waveform generator component in turn connected to an amplifier section with a filter network, the latter being connected to sensing and conditioning circuit componentry that is in turn connected to analog-to-digital converter circuitry. A digital memory stores digitized voltage and current waveform information. The processor determines a phase difference between voltage and current waveforms, compares the determined phase difference to a phase difference command and generates a phase error or correction signal. The processor also generates an amplitude error signal for inducing the amplifier section to change its output amplitude to result in a predetermined amplitude error level for a respective one of the voltage and current waveforms.
