    摘要: Ultrasound application devices and methods of use for sternum healing of a patient includes the steps of positioning an ultrasound application device near a sternum having approximated portions, and applying ultrasound to the approximated portions for promoting healing. The ultrasound application device includes a transducer for generating the ultrasound, and a base for positioning the transducer near to the sternum. A diverging lens may be disposed between the transducer and the sternum for acoustically diverging the ultrasound to flood the sternum with ultrasound. A plurality of transducers may be included in a plurality of recesses of the base along a longitudinal length of the sternum for applying the ultrasound along the longitudinal length of the sternum. A ring may be included to be positioned and secured about the neck of the patient. The ring may be woven as and/or incorporated in a tie. A metal strip may be used which responds to signals from the transducer for generating the ultrasound applied to the sternum. The metal strip may be implanted within the patient substantially adjacent to the sternum. Also, the ultrasound application device may operate in conjunction with a mesh implanted in the patient substantially adjacent to the sternum.

    摘要: A magnetostrictive ultrasonic dental scaler is disclosed. The magnetostrictive device comprises an oscillator adapted to provide electrical energy including a current and a voltage signal, a handpiece having a tool tip which vibrates in response to the electrical energy supplied to the handpiece and a control circuit. The control circuit includes a phase detector adapted to detect phase between current and voltage signals and to generate a phase detection signal as a function of the phase. The control circuit also includes a digital signal processor operatively connected to the phase detector. The digital signal processor adapted to process the phase detection signal through a digital loop filter to generate an error signal. The control circuit further includes a voltage controlled oscillator operatively connected to the digital signal processor, wherein the error signal outputs a voltage to operate the voltage controlled oscillator which in response thereto adjusts at least one of frequency and amplitude of vibrations of the tool tip.

    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.

    摘要: A controller for driving an ultrasonic transducer is disclosed and includes a processor, responsive to a feedback signal, for generating control signals to an output driver which is responsive to the control signals, to cause the ultrasonic transducer to generate ultrasound having a power level corresponding to the control signal. The controller is preferably attached to a sensing circuit to determine the amount of ultrasound conductive gel associated with the ultrasonic transducer, and for generating the feedback signal therefrom. The controller includes data logging capabilities to record treatment data and prevent unnecessary extended treatment. The controller creates an environment for safer ultrasonic self-treatment by patients. The microprocessor used in the controller can be used to warn of a low battery condition or insufficient amount of ultrasound conducting gel. It can limit the usage of the transducer to prevent over treatment by comparing use data with acceptable limits and disabling the transducer if the limits have been exceeded. The device is contemplated to be portable for ease of transport by patients.
