Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of acupuncture and moxibustion, and particularly relates to an active waveguide type laser heating acupuncture needle and an application method thereof. BACKGROUND

[0002] Acupuncture and moxibustion is a general term for acupuncture and moxibustion. Acupuncture is to insert a needle into the body of a patient according to a certain angle under the guidance of traditional Chinese medicine theory, and to stimulate specific acupoints of the human body by using rotating and lifting and inserting needle manipulation, so as to achieve the purpose of treating diseases. Moxibustion is to burn or fumigate a prepared moxa cone or moxa grass on a certain acupoint on the body surface, and to use the heat stimulation to prevent and treat diseases. One of the methods is warm acupuncture, which is a method combining acupuncture and moxibustion, also known as needle handle moxibustion. That is, during the needle retention process, a moxa roll is twisted and wrapped around the needle handle, ignited, or an ai roll is cut into a section about 2 cm long, inserted into the needle tail, ignited and warmed, and the heat is transmitted to the acupoint through the needle body. This method has the effects of warming meridians, dispelling cold, supporting yang and tonifying qi, and has the effects of dispelling cold and dampness, unblocking meridians, and treating joint pain, numbness of the skin, etc. Its indications are not limited to wind-damp diseases, and is mainly used for cold-type diseases such as osteoarthritis, cold pain of the skin, abdominal distension, and diarrhea, etc., thus expanding the treatment of various diseases

[0003] Traditional warm acupuncture has the following shortcomings: 1. It is necessary to prevent the ai fire from falling off and burning the skin, and a hard paper is cut into a circular paper piece in advance, and a small gap is cut in the center, and placed on the acupoint area under the needle, which is not convenient to operate. 2. The burning of the ai leaves on the needle handle produces smoke and ash, polluting the indoor environment. 3. The temperature of the needle body cannot be accurately controlled, and the heating frequency and time are difficult to accurately control. 4. The load of the needle handle is too heavy, which is not conducive to the subsequent operation of the doctor.

[0004] Based on the above problems, acupuncture and moxibustion needles using laser heating are gradually popularized. The existing patent application No. CN113749941A discloses a light radiation temperature regulation internal heating acupuncture needle, which comprises a needle handle, a laser input end, a first shielding layer, a second shielding layer, a fiber body, a collimating mirror, a focusing mirror, a heat collecting sheet, a heat conducting needle, a temperature sensor, a needle tip, a needle shaft and a temperature display.

[0005] In the above technical solution, the laser input end is provided on the needle for external connection of a laser source, which leads to a relatively dense and messy light source line when multiple needles are used, affecting the acupuncture operation, and being not convenient to operate and store. SUMMARY

[0036] Based on the above technical solutions, a preferred embodiment also includes a collar, one end of which is fitted onto the battery and the other end is inserted into the inner sleeve.

[0037] On the other hand, the present invention provides a method for applying the above-mentioned active waveguide laser heating acupuncture needle, comprising the following steps:

[0038] S1. Output laser light from the first laser source.

[0039] S2. The laser is refracted by a refracting prism and coupled to the end of the needle body through an irregular waveguide lens, and then the laser is output from the end of the needle body.

[0040] In application, the light source is selectively adjusted according to the working conditions. In stand-alone application mode, the battery is used as the primary laser source to achieve laser output.

[0041] In the external application mode, rotate the needle handle so that the light source connector aligns with the reflecting surface of the refractive prism, and connect the light source connector to the external laser to achieve laser input.

[0042] The active waveguide-type laser-heated acupuncture needle and its application method of the present invention have the following advantages over the prior art:

[0043] (1) By setting a lens group and a first laser source inside the acupuncture needle, the acupuncture needle does not need an external laser source. It has the advantages of being lightweight, highly integrated, and having a small needle handle load. It can be used independently as conveniently as a traditional acupuncture needle, without being interfered with by the light source line, and is convenient for acupuncture.

[0044] (2) The handle of this acupuncture needle is equipped with a light source connector, and the position of the light source connector and the first laser source is adjustable. In this way, the positions of the light source connector and the first laser source can be swapped and corresponding to the lens group. In this way, this acupuncture needle can also be used with an external laser source, so that the acupuncture needle can still perform acupuncture operation when the first laser source is damaged or the power is exhausted, which further improves the convenience of application.

[0045] (3) The acupuncture needle is equipped with a reflective film and an irregular waveguide lens, which can couple light to the front end of the needle body to achieve needle body heating or laser output, thereby stimulating acupoints. This structure has the advantages of using fewer lenses and being easy to integrate.

[0046] (4) The needle handle and the needle body are connected by a connecting sleeve, an outer sleeve and an inner sleeve. The outer sleeve, the inner sleeve, the needle body and the refractive prism are relatively fixed, while the needle handle used to install the first laser source and the light source connector is rotatably connected to the outer sleeve. In this way, the first laser source and the light source connector can be switched by rotating the needle handle, which has the advantage of convenient adjustment.

[0047] (5) By setting the irregular waveguide lens as a stepped structure, the connecting sleeve can be set between the irregular waveguide lens and the outer sleeve. The connecting sleeve is made of insulating plastic material. When welding the outer sleeve and the needle body, the connecting sleeve can rely on deformation to achieve buffering. The deformation caused by welding heat is not easy to interfere with the irregular waveguide lens, which is conducive to ensuring the overall stability and application reliability of the acupuncture needle.

[0048] (6) The first laser source has an electrode connection substrate, a laser chip and a control button. The laser output can be realized by connecting the electrode connection substrate with a battery and then powering the laser chip. The whole is small and convenient. At the same time, the electrode connection substrate is set as an arc plate structure and is fitted into the groove of the needle handle. Its arc is set to be less than half a circle. This can avoid interference between the inner sleeve and the needle handle as much as possible, which is conducive to ensuring the stability of the position of the inner sleeve and the refractive prism, thereby ensuring the reliability of the application.

[0059] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0060] like Figures 1-8 As shown, the active waveguide laser-heated acupuncture needle of the present invention includes a needle body 1, a needle handle 2, a lens group 3, a first laser source 4, a light source connector 5, a connecting sleeve 6, an outer sleeve 7, an inner sleeve 8, and a collar 9.

[0061] like Figures 1-4 As shown, the needle body 1 has a hollow structure; the needle handle 2 is located on one end of the needle body 1 and is connected to the needle body 1; the lens group 3 is located inside the needle body 1 and the needle handle 2, and the lens group 3 is fixed relative to the needle body 1; the first laser source 4 is located inside the needle handle 2; the light source connector 5 is located on the needle handle 2, and the positions of the first laser source 4 and the light source connector 5 are adjustable so that one of them corresponds to the lens group 3;

[0062] As described above, in this acupuncture needle, the needle body 1 and the needle handle 2 are configured to be connected, so that the lens group 3 and the first laser source 4 can be internally housed.

[0063] The lens group 3 is located in the needle body 1 and the needle handle 2, while the first laser source 4 is integrated with the needle handle 2. The heating function can be achieved by emitting laser from the first laser source 4 to the lens group 3. In this way, the acupuncture needle can be used independently without the need for an external laser source. It has the advantages of being lightweight, highly integrated, and having a small needle handle load. It can be used independently as conveniently as a traditional acupuncture needle, without being affected by the light source line, and is convenient for acupuncture.

[0064] Meanwhile, the acupuncture needle handle 2 is equipped with a light source connector 5, and the position of the light source connector 5 and the first laser source 4 is adjustable. In this way, the positions of the light source connector 5 and the first laser source 4 can be interchanged and correspond to the lens group 3. Thus, this acupuncture needle can also be used with an external laser source, so that the acupuncture needle can still perform acupuncture operations when the first laser source is damaged or the power is exhausted. It is suitable for a variety of scenarios and further improves the convenience of application.

[0065] like Figures 1-4 As shown, the inner wall of the needle body 1 is coated with a reflective film. The lens group 3 includes an irregular waveguide lens 31 and a refractive prism 32. The irregular waveguide lens 31 is disposed inside the needle body 1. The refractive prism 32 is disposed inside the needle handle 2, and the refractive prism 32 is fixed relative to the irregular waveguide lens 31. The first laser source 4 and the refractive prism 32 are both corresponding to the refractive prism 32, and the first laser source 4 and the refractive prism 32 can rotate relative to the refractive prism 32.

[0066] As described above, the lens group 3 consists of an irregular waveguide lens 31 and a refractive prism 32, wherein the irregular waveguide lens 31 is integrated inside the needle body 1 and is used to couple the laser to the end of the needle body 1.

[0067] Specifically, the refractive index of the irregular waveguide lens 31 is gradually changed. During its fabrication, the medium is selected to adapt to the length of the needle body 1 to ensure the optical coupling effect.

[0068] The refractive prism 32 is disposed inside the needle handle 2 and is fixed relative to the irregular waveguide lens 31. The refractive prism 32 is used to refract the laser light source into the irregular waveguide lens 31. Thus, when the first laser source 4 and the light source connector 5 are rotated and repositioned, they can selectively align with the refractive prism 32, thereby enabling the light source to be selected. This allows the acupuncture needle to be used independently or with an external light source.

[0069] The refracting prism 32 has a reflective inclined surface, the angle of which is determined by the relative position of the irregular waveguide lens 31 and the first laser source 4; preferably, the refracting prism 32 is a 45-degree inclined prism.

[0070] When applied, the laser from the first laser source 4 or the laser input from the external light source connected to the light source connector 5 is reflected by the refractive prism 32 to the irregular waveguide lens 31, and then coupled to the end of the needle body 1 by the irregular waveguide lens 31 to realize the heating of the needle body or the laser output, thereby stimulating the acupoint. This structure has the advantages of using fewer lenses and being easy to integrate.

[0071] The inner wall of the needle body 1 is coated with a reflective film to ensure efficient coupling and transmission of the laser.

[0072] Specifically, the needle body 1 has an inner diameter of approximately 0.35 mm. During the manufacturing process, the inner wall surface finish is better than 0.1 μm. The coating is designed to meet the requirements of higher transmission efficiency. After coating, the reflectivity can be increased to over 0.9. Chemical plating or hot-dip plating methods can be used, and gold is used as the coating material.

[0073] The length of the irregularly shaped waveguide lens 31 varies depending on the needle length. The designed length of the irregularly shaped waveguide lens 31 determines the size of the emitted light spot. For example, for a 1.5-inch needle (40mm long), using red light at a wavelength of 650nm, three types of light spots are achieved: parallel, divergent, and converging. If the length of the irregularly shaped waveguide lens 31 is designed to be 32.5mm, the emitted light spot will be a parallel light of constant size. To enlarge or reduce the light spot, the length of the irregularly shaped waveguide lens 31 can be designed to be 31.0mm or 34.0mm. If using light with a wavelength of 1100nm, the length of the irregularly shaped waveguide lens 31 is designed to be 36.85mm, 36.2mm, and 37.15mm for parallel, divergent, and converging light spots, respectively. If a 3-inch (75mm long) or other length acupuncture needles are used, the length of the irregularly shaped waveguide lens 31 can be designed similarly.

[0074] Meanwhile, for the same needle length, using light sources of different wavelengths can control the size of the desired light spot. The radial refractive index envelope of the gradient lens decreases exponentially from 1.496 at the needle axis position to 1.470 at the edge position along the radius.

[0075] like Figures 5-7 As shown, one end of the needle body 1 has a conical structure, and the other end has a cylindrical structure. The irregular waveguide lens 31 has a stepped structure, and the small-diameter section 311 of the irregular waveguide lens 31 is located inside the cylindrical end of the needle body 1. The connecting sleeve 6 is fitted onto the small-diameter section 311. The connecting sleeve 6 has a first section 61 located between the needle body 1 and the small-diameter section 311, and a second section 62 abutting the end of the needle body 1. The outer sleeve 7 is fitted onto the needle body 1 and the second section 62, and the outer sleeve 7 is relatively fixed to the needle body 1. One end of the inner sleeve 8 is fitted onto the second section 62 and is relatively fixed to the outer sleeve 7. The refractive prism 32 is disposed inside the inner sleeve 8. The needle handle 2 is fitted onto the inner sleeve 8 and is rotatably connected to the outer sleeve 7.

[0076] As described above, the needle body 1 is set at one end in a conical shape for acupuncture use, while the other end is set at a cylindrical shape for the needle handle 2.

[0077] The irregular waveguide lens 31 is configured as a stepped structure, which has a small diameter section 311, and the small diameter section 311 is fitted with a connecting sleeve 6. The first section 61 of the connecting sleeve 6 is located between the small diameter section 311 and the needle body 1, and the second section 62 abuts against the end of the needle body; thus, the irregular waveguide lens 31 can be limited, thereby ensuring structural stability.

[0078] The outer sleeve 7 is fitted onto the needle body 1 and the second section 62, which can further ensure the overall structural stability; at the same time, the outer sleeve 7 is used to connect the inner sleeve 8 and the needle handle 2.

[0079] In this structure, the inner sleeve 8 is used to install the refractive prism 32 to achieve relative fixation between the refractive prism 32 and the irregular waveguide lens 31; the needle handle 2 is rotatably connected to the outer sleeve 7. Thus, by rotating the needle handle 2, the first laser source 4 and the light source connector 5 can be rotated and repositioned, thereby selectively corresponding to the reflecting surface of the refractive prism 32 to achieve light source input selection, which has the advantage of convenient adjustment.

[0080] Specifically, the connecting sleeve 6 is made of insulating plastic, while the outer sleeve 7 and the needle body 1 are made of metal, and the outer sleeve 7 and the needle body 1 are welded and fixed together.

[0081] As described above, the connecting sleeve 6 is made of insulating rubber, and the outer sleeve 7 is connected to the needle body by welding, which helps to ensure sealing.

[0082] Meanwhile, since the irregular waveguide lens 31 is set as a stepped structure, the connecting sleeve 6 can be placed between the irregular waveguide lens 31 and the outer sleeve 7. The connecting sleeve 6 is made of insulating plastic material. In this way, when welding the outer sleeve 7 and the needle body 1, the connecting sleeve 6 can rely on deformation to achieve buffering. The deformation of the needle body caused by welding heat is less likely to interfere with the irregular waveguide lens 31, which is conducive to ensuring the overall stability and application reliability of the acupuncture needle.

[0083] like Figure 7 As shown, the needle handle 2 includes a connecting cylinder 21, an end cap 22, and a battery 23. The connecting cylinder 21 is sleeved on the inner sleeve 8 and rotatably connected to the outer sleeve 7. The end cap 22 is located on the end of the connecting cylinder 21 away from the needle body 1. The battery 23 is located inside the end cap 22 and is electrically connected to the first laser source 4.

[0084] As described above, the needle handle 2 is rotatably connected to the outer sleeve 7 via the connecting sleeve 21. At the same time, the connecting sleeve 21 is used to integrate the refractive prism 32 and the first laser source 4.

[0085] One end of the needle handle 2 is sealed by an end cap 22, which is used to integrate a battery 23. The battery 23 is used to power the first laser source 4. This structure makes the layout of each module reasonable, and the end cap 22 can be set as a detachable structure, which makes it easy to replace the battery 23.

[0086] like Figure 7As shown, the first laser source 4 includes an electrode connection substrate 41, a laser chip 42, and a control button 43. The needle handle 2 has a groove 201, the electrode connection substrate 41 is disposed in the groove 201, and the electrode connection substrate 41 is electrically connected to the battery 23. The laser chip 42 is disposed on the electrode connection substrate 41 and is electrically connected to the electrode connection substrate 41. The control button 43 is connected to the electrode connection substrate 41 and passes through the needle handle 2. The inner sleeve 8 has a light-transmitting hole 801, which corresponds to the light-emitting end of the laser chip 42.

[0087] As described above, the first laser source 4 has an electrode connection substrate 41, a laser chip 42, and a control button 43. Thus, by connecting the electrode connection substrate 41 to the battery 23 and then supplying power to the laser chip 42, laser output can be achieved. The whole structure is compact and convenient.

[0088] Meanwhile, the electrode connection substrate 41 is set as an arc-shaped plate structure and is fitted into the groove 201 of the needle shank, which helps to ensure the compactness of the structure and make its integration higher.

[0089] Since the refracting prism 32 is set in the inner sleeve 8, a light-transmitting hole 801 is opened on the inner sleeve 8 so that the laser can be emitted to the reflecting surface of the refracting prism 32.

[0090] Among them, the control button 43 is the control component of the laser chip 42. It can be configured to control the switch of the laser chip 42 or integrate the chip power adjustment function. It is a conventional solution, so it will not be described in detail.

[0091] The laser chip 42 controls the mode, frequency and power of the output laser, thereby achieving the purpose of regulating the heating mode, duration and temperature of the needle tip area and the position of the heating area, so as to realize the precise temperature control and therapeutic effect control of acupuncture needles and make them widely usable by medical personnel.

[0092] Specifically, the laser chip 42 can be selected to achieve the same far-infrared transmission effect as moxibustion, thus providing continuous and effective stimulation to acupoints. At the same time, in conjunction with the irregularly shaped waveguide lens 31, the size and position of the light radiation area near the needle tip can be micro-adjusted. Pulsed or continuous heating of the acupoint area can be applied according to the treatment needs, so as to achieve one prescription for one disease and treat according to the prescription, thereby further improving the efficacy of acupuncture.

[0093] like Figure 4 As shown, the electrode connection substrate 41 is configured as an arc-shaped plate structure, and the arc of the electrode connection substrate 41 is less than half a circle.

[0094] As described above, in order to adapt to the integrated structure of the needle handle 2, the electrode connection base 41 is set as an arc-shaped plate structure, and its curvature is set to be less than half a circle. This can ensure the contact area between the inner sleeve 8 and the needle handle 2 as much as possible, thereby ensuring the structural stability of the inner sleeve 8.

[0095] like Figure 7 As shown, the electrode connecting base 41 is spaced apart from the inner sleeve 8. In some embodiments, the portion of the electrode connecting base 41 without the laser chip 42 is made thicker to support the inner sleeve 8. In this way, the curvature of the electrode connecting base 41 is no longer restricted, and the inner sleeve 8 can be kept stable by the support of the electrode connecting base 41.

[0096] like Figure 8 As shown, one end of the collar 9 is fitted onto the battery 23, and the other end is inserted into the inner sleeve 8;

[0097] As described above, the collar 9 is used to further ensure structural stability. Since the inner sleeve 8 is used to support the refractive prism 32, the collar 9 is used for positioning and support to avoid deformation of the inner sleeve 8 due to the weight of the refractive prism 32.

[0098] In this structure, the collar 9, battery 23 and end cap 22 are rigidly connected.

[0099] Specifically, the needle body 1 has a through-type structure; in this way, the acupuncture needle can perform acupuncture by heating the end of the needle body 1, or by emitting a laser, making it versatile.

[0100] The present invention utilizes the above-described active waveguide laser-heated acupuncture needle method, comprising the following steps:

[0101] S1. Output laser light from the first laser source 4.

[0102] S2. The laser light is refracted by the refracting prism 32 and coupled to the end of the needle body 1 through the irregular waveguide lens 31. The laser light is then output from the end of the needle body 1. In application, the light source can be selectively adjusted according to the working conditions.

[0103] In the stand-alone application mode, the battery 23 powers the first laser source 4 to achieve laser output; in the external application mode, the needle handle 2 is rotated so that the light source connector 5 corresponds to the reflecting surface of the refractive prism 32, and the light source connector 5 is connected to an external laser to achieve laser input.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
