Abstract

The invention discloses a transcranial ultrasound stimulation cranial-nerve-function-repairing device and a method. The device comprises a function signal generator, a power amplifier, and an ultrasonic transducer, wherein after the function signal generator produces stimulation signals needed by stimulation, the stimulation signals are amplified though the power amplifier to high voltage pulse signals needed by the ultrasonic transducer and then ultrasonic stimulation signals are obtained through the ultrasonic transducer to stimulate brain tissue. The transcranial ultrasound stimulation cranial-nerve-function-repairing device and the method can achieve the purposes of low-power, high-resolution, and non-invasive neural restoration treatment.

Description

technical field [0001] The invention relates to a cerebral cortex stimulation technology, in particular to a device and method for transcranial ultrasonic stimulation to repair brain nerve function. Background technique [0002] Therapeutic ultrasound can be divided into low-power therapeutic ultrasound (usually less than 0.5W / cm2) and high-power therapeutic ultrasound (greater than 100W / cm2). Ultrasound can be transmitted to various tissues of the human body (including bones) in the form of continuous waves or pulses. Therapeutic ultrasound with an intensity lower than 0.5W / cm2 mainly achieves the therapeutic effect by interacting with tissues through non-thermal effects including mechanical force. The safety of low-intensity ultrasound used in diagnostic ultrasound on human tissue is regularly and professionally reviewed. The wide clinical application of medical ultrasound has basically confirmed the safety of low-intensity ultrasound on biological tissues. [0003] At ...
