Ultrasonic Acupuncture Device

technical field

The invention relates to the technical field of ultrasonic therapy, and in particular provides an ultrasonic acupuncture device.

Background technique

Acupuncture and moxibustion is a unique disease treatment method in my country. Acupuncture can dredge the meridians, even if the blocked meridians are unobstructed, so that it can play a normal physiological role. It is used in many fields of traditional Chinese medicine, such as: allergic rhinitis, acute and chronic laryngitis, bronchitis and other respiratory diseases; acute conjunctivitis, central retinitis, cataract and other eye diseases; toothache. Treatment and improvement of oral diseases such as gingivitis, as well as other acute and chronic diseases. Not only that, acupuncture can also accelerate the basal metabolic rate by stimulating the meridians, promote fat metabolism, increase heat production, consume accumulated fat, and then adjust, improve, and restore the body's own balance to achieve the goal of weight loss. Acupuncture therapy also has many advantages: it has a wide range of indications, and can be used for the treatment and prevention of various diseases in internal medicine, surgery, gynecology, pediatrics, facial features and other departments; the effect of treating diseases is relatively rapid and significant, especially with good excitatory body functions , improve disease resistance, sedation, analgesia and other effects; the operation method is simple and easy; medical expenses are economical; and there are no or very few side effects, basically safe and reliable. It can also be combined with other treatment methods for comprehensive treatment. Acupuncture and moxibustion has always been to use needles to penetrate the patient's body at a certain angle and stimulate specific parts to achieve the purpose of treatment. However, there are some risks in traditional acupuncture treatment, such as unsafe factors such as fainting, stuck needles, bent needles, bleeding and infection. Ultrasonic stimulation has received more and more attention in medical diagnosis and treatment due to its advantages of easy concentration of energy, strong penetrating power, good directionality, and zero or minimal damage to human tissue. Nowadays, many laboratories are using ultrasound instead of traditional needles to stimulate the acupuncture points of the human body, so as to achieve the purpose of treatment.

Common ultrasonic self-focusing transducers mainly include spherical self-focusing, multi-element self-focusing and electronic phased array focusing transducers. Self-focusing transducers are easy to process at low frequencies, but it is difficult to process self-focusing transducers at high frequencies. Moreover, each transducer unit of the multi-element self-focusing and electronic phased array transducer needs to independently control the phase and amplitude, which is relatively cumbersome to design and complicated to operate.

The 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 regulating structure 20, that is, the incident frequency of the high-frequency ultrasonic waves is changed to correspond to Changing the depth of focus can precisely stimulate the position and depth of acupuncture points. At the same time, the acoustic wave collimator 30 further adjusts the focused high-frequency ultrasonic waves, that is, changes the position and depth of the stimulated acupuncture points.

Specifically, please refer to FIG. 3 , in this embodiment, the control structure 20 includes a plurality of circular rings 21a arranged concentrically and with the same thickness, a slit 22a is formed between every two adjacent circular rings 21a, and, The width of each slit 22a gradually decreases from the inside to the outside along 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 (that is, the control structure 20) forms a Fresnel area; the slit a and the ring b form a Fresnel area; the slit a, the ring b and the slit c form a Fresnel area; Slit a, ring b, slit c and ring d form a Fresnel area; slit a, ring b, slit c, ring d and slit e form a Fresnel area; slit a , ring b, slit c, ring d, slit e, and ring f form a Fresnel area; slit a, ring b, slit c, ring d, slit e, and ring f and slit g form a Fresnel area; slit a, ring b, slit c, ring d, slit e, ring f, slit g and ring h form 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 _x represents the radius of the nth (n=1, 2, 3, ..., N) Fresnel zone; λ=c/f represents the wavelength of the sound wave emitted by the planar ultrasonic probe, c represents the speed of sound, and f represents The center frequency of the sound wave emitted by the planar ultrasonic probe; F represents the preset focal length; d _i (i=1) represents the radius of the central circular hole; d _i (i>1) represents the radius of the ring or other slits except the central circular hole Width; r _i represents the radius of the smallest Fresnel region containing the i-th ring or slit, and r _j represents the radius of the largest Fresnel region smaller than the above minimum Fresnel region within the above minimum Fresnel region . The planar ultrasonic probe mentioned here refers to a planar ultrasonic probe that needs to be used in conjunction with an acoustic wave focusing lens.

Each ring structure 22b is composed of several round holes 23b, and the diameter of the round holes 23b of each ring structure 22b gradually decreases from inside to outside along the radial direction. Similarly, since the diameters of the circular holes 23b of the ring structures 22b are different and tend to decrease gradually, the parallel sound waves emitted by the planar ultrasonic probe 10 can be concentrated.

Specifically, please refer to Fig. 5 and Fig. 6, in this embodiment, the control structure 20 includes several semicircular grids 21c arranged concentrically, a gap 22c is formed between every two adjacent semicircular grids 21c, and each semicircle The grids 21c are radially spaced from inside to outside in the radial direction, and the radius of each semicircular grid 21c gradually increases along the radial direction. Similarly, 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 since the control structure 20 is eccentrically arranged, the sound waves pass away from When the semicircular grid 21c at the eccentric position, the greater the focusing angle, and so on, the closer to the semicircular grid 21c at the eccentric position, the smaller the focusing angle, that is, high-frequency ultrasonic waves can bypass obstacles in the sound wave transmission path, and The position and energy of the self-bending focal spot are not affected.

Specifically, in this embodiment, the material of the regulating structure 20 is any one of resin, silicon wafer, and metal. Since the regulating 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 waves of the planar ultrasonic probe 10 is relatively high (as above 10 MHz), since the volume of the planar ultrasonic probe 10 is relatively small, the corresponding ring can be made of materials with easy-to-process microstructures such as silicon wafers. If the center frequency of the sound waves of the planar ultrasonic probe 10 is relatively low (such as less than 10MHz), since the volume of the planar ultrasonic probe 10 is relatively large, a metal material can be selected to make the ring, and certainly, a silicon wafer can also be selected to make the ring. .

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 can 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, 65.0MHz MHz, 70.0MHz, 75.0MHz, 80.0MHz, 85.0MHz, 90.0MHz, 95.0MHz, 100.0MHz.
