Embodiments of the present invention

At present, ultrasound technology is used to stimulate human tissue, and several effects are produced to cause changes in diseased tissue, so as to achieve the purpose of treatment. These ultrasonic effects are mainly thermal effects, mechanical effects and cavitation effects.

In the stimulation mechanism of the thermal effect, part of the sound energy is absorbed by the medium due to the viscosity and thermal conductivity of the medium during the propagation of the ultrasonic wave, and the result is converted into heat energy and causes the local temperature to rise. After the tissue is subjected to this thermal effect, certain reactions occur, such as vasodilation, accelerated blood circulation, and increased tissue metabolism, thereby promoting the absorption and dissipation of pathological products.

In the stimulation mechanism of mechanical effect, during the propagation of ultrasonic waves, the mechanical effect of particle vibration in the medium causes acceleration, rotation, and rushing vibrations of some fine tissues, thus playing a massage role and enhancing the semi-permeable membrane. It also has a good effect on the material exchange of cells and tissue nutrition.

In the stimulation mechanism of the cavitation effect, during the propagation of ultrasonic waves, when sufficient ultrasonic intensity encounters some liquid tissues in the human body, cavitation will be generated, which can generate high-intensity micro shock waves, which can change or destroy lesions tissue for therapeutic purposes.
