The ultrasonic acupuncture device provided by the embodiment of the present invention includes a planar ultrasonic probe 10, a control structure 20 for regulating high-frequency ultrasonic waves, and an acoustic wave collimator 30, and a planar ultrasonic probe 10. The control structure 20 and the sound wave collimator 30 are arranged in sequence along the sound wave propagation direction.

The working principle of the ultrasonic acupuncture device provided by the embodiment of the present invention is as follows: the planar ultrasonic probe 10 can generate parallel high-frequency ultrasonic beams, and the high-frequency ultrasonic waves are focused after passing through the control structure 20, that is, the incident frequency of the high-frequency ultrasonic waves is changed to correspond to By changing the focus depth, the position and depth of the acupuncture points can be accurately stimulated. At the same time, the acoustic wave collimator 30 further adjusts the focused high-frequency ultrasound, that is, changes the position and depth of the stimulation points.

Specifically, referring to FIG. 3, in this embodiment, the regulating structure 20 includes a plurality of concentric rings 21a with the same thickness, and a slit 22a is formed between every two adjacent rings 21a, and, The width of each slit 22a gradually decreases from the inside to the outside in the radial direction. Optionally, the ring 21a may be a silicon ring, or may be a metal ring, such as an aluminum ring, or a steel ring.

Specifically, the width of the ring 21a and the width of the slit 22a are determined according to the Fresnel diffraction formula. The slit a (ie, the control structure 20) constitutes a Fresnel area; the slit a and the ring b constitute a Fresnel area; the slit a, the ring b and the slit c constitute a Fresnel area; the slit Slit a, ring b, slit c and ring d constitute a Fresnel area; slit a, ring b, slit c, ring d and slit e constitute a Fresnel area; slit a , Ring b, slit c, ring d, slit e and ring f constitute a Fresnel area; slit a, ring b, slit c, ring d, slit e, ring f And slit g constitute a Fresnel area; slit a, ring b, slit c, ring d, slit e, ring f, slit g and ring h constitute a Fresnel area. So, and so on.

Specifically, the width of the ring 21a and the width of the slit 22a are determined according to the following formula:

d _i (i=1)=r ₁ ,

_{d i (i> 1) =} r i -r j,

Among them, r _n represents the radius of the nth (n=1, 2, 3,..., N) Fresnel zone;

Represents the acoustic wavelength emitted ultrasound probe plane, c denotes the speed of sound, f denotes the center frequency of the transmitted ultrasonic probe plane acoustic wave; F. Represents a predetermined focal length; d _{i (i} = 1) represents a radius of the center circular hole; d _{i (i} >1) represents the width of the ring or other slits other than the central circular hole; r _i represents the radius of the smallest Fresnel zone containing the i-th ring or slit, r _j represents the minimum Fresnel zone above, The radius of the largest Fresnel zone that is smaller than the aforementioned minimum Fresnel zone. The planar ultrasound probe mentioned here refers to a planar ultrasound probe that needs to be used in conjunction with an acoustic wave focusing lens.

Specifically, referring to FIG. 4, in this embodiment, the regulating and controlling structure 20 includes a body 21b.

Similarly, since the diameters of the circular holes 23b of the circular ring structures 22b are all different and gradually decrease, the parallel sound waves emitted by the planar ultrasonic probe 10 are concentrated.

Specifically, please refer to Figures 5 and 6, in this embodiment, the regulating and controlling structure 20 includes a plurality of concentrically arranged semicircular grids 21c, and a gap 22c is formed between every two adjacent semicircular grids 21c, each semicircular The grids 21c are radially spaced from the inside to the outside in the radial direction, and the radius of each semicircular grid 21c gradually increases in the radial direction. In the same way, the control structure composed of concentrically arranged semicircular grids 21c also has a focusing effect on the parallel sound waves emitted by the planar ultrasonic probe 10, and because the control structure 20 is eccentrically arranged, the sound waves pass away from each other. When the semicircular grid 21c is off-center, the focus angle is larger, and so on, the closer to the semicircular grid 21c at the eccentric position, the smaller the focus angle is, that is, high-frequency ultrasonic waves can bypass obstacles in the sound wave transmission path. Does not affect the position and energy of the self-bending focal spot.

Specifically, in this embodiment, the material of the control structure 20 is any one of resin, silicon wafer, and metal. Since the control structure 20 is used in conjunction with the planar ultrasonic probe 10, the material of the ring can be determined according to the frequency of the sound wave of the planar ultrasonic probe 10. For example, if the center frequency of the sound wave of the planar ultrasonic probe 10 is relatively high (such as above 10MHz), since the volume of the planar ultrasonic probe 10 is relatively small, the corresponding ring can be made of silicon wafer and other materials with easy-to-process microstructures. If the center frequency of the sound wave of the planar ultrasonic probe 10 is relatively low (for example, less than 10MHz), since the volume of the planar ultrasonic probe 10 is relatively large, metal materials can be used to make the ring at this time. Of course, silicon wafers can also be used to make the ring at this time. .

Specifically, in this embodiment, the frequency range of the planar ultrasonic probe 10 is 0.2 MHz-100 MHz. For example, the frequency of the planar ultrasonic probe 10 may be 0.2MHz, 1.0MHz, 5.0MHz, 15.0MHz, 20.0MHz, 25.0MHz, 30.0MHz, 35.0MHz, 40.0MHz, 45.0MHz, 50.0MHz, 55.0MHz, 60.0MHz, 65.0 MHz, 70.0MHz, 75.0MHz, 80.0MHz, 85.0MHz, 90.0MHz, 95.0MHz, 100.0MHz.
