Description

Technical Field

[0001] This invention relates to the field of needle body heat insulation technology, and in particular to an adjustable needle body heat insulation protection method for Mongolian medicine warm needle therapy. Background Technology

[0002] In existing technologies, traditional silver / copper needles in Mongolian medicine's warm needling therapy are gradually being replaced by stainless steel needles, which are more corrosion-resistant. Electronic warm needling therapy devices are being developed to regulate needle temperature and heating time. Combined with the Mongolian medicine's "three roots" diagnostic method, high-temperature, long-duration stimulation is used for heat syndromes, while low-temperature, short-duration stimulation is used. Infrared thermal imaging technology is used to monitor temperature distribution at the treatment site, optimizing the heating scheme. A common adjustable method involves using a heat-resistant hollow sleeve made of a hollow material, fitted over the needle. The sleeve's position on the needle is adjusted by axial sliding, thus changing the exposed length of the needle. The heat insulation structure is divided into multiple detachable modules, connected by threads, snaps, or magnetic attraction, and combined to achieve the required total length based on the needle length and acupoint depth. Alternatively, elastic heat-resistant materials, such as silicone tubes or elastic ceramic fiber tubes, are used to adjust the coverage length. After the silicone tube is fitted into the sleeve, the coverage area is extended by stretching or shortened by compression, relying on the material's elastic recovery force to maintain its position. Silicone, ceramic, and Teflon are primarily used as heat insulation materials.

[0003] Chinese Patent Publication No. CN120938799A discloses an acupuncture needle for warm needling in Traditional Chinese Medicine, comprising a needle body, a moxibustion fixing part, and an acupuncture part located below the moxibustion fixing part. The central axis of the moxibustion fixing part and the central axis of the acupuncture part coincide. The acupuncture part includes an inner metal body, a thermally conductive reinforcing layer formed outside the metal body, and a phase change insulation layer formed outside the thermally conductive reinforcing layer. The phase change insulation layer is made of a material with a phase change temperature of 42-45°C. Therefore, the acupuncture needle for warm needling in Traditional Chinese Medicine suffers from problems such as needle body displacement due to physiological micro-movements or surface curvature during needle insertion caused by irregular surface curvature of the acupuncture site, accompanied by respiration or muscle tremors, resulting in uneven heat conduction and local hot spots or heat accumulation. Summary of the Invention

[0004] Therefore, the present invention provides an adjustable needle body heat insulation protection method for Mongolian medicine warm needle therapy, in order to overcome the problems in the prior art where the needle body is deviated due to physiological micro-movement or surface curvature caused by the continuous slight displacement deviation of the needle point position due to the irregular surface curvature of the needle insertion site accompanied by breathing or muscle tremors, and the uneven heat conduction during needle heating, resulting in local hot spots or heat accumulation.

[0005] To achieve the above objectives, the present invention provides an adjustable needle body heat insulation protection method for Mongolian medicine warm needling therapy, comprising: Obtain the curvature model and physiological micro-motion amplitude of the surface at the acupuncture site, and detect the alignment tilt deviation angle of the needle body; The pre-set tilt direction of the needle body's support and the heat insulation separation height from the skin are determined based on the curvature model. The decay acceleration of the preparatory oscillation of the needle body along the preset tilt direction is determined based on the physiological micro-motion amplitude. The opening of the pressure relief passage for conducting heat and relieving pressure to the environment around the needle is determined based on the aforementioned positive tilt deviation angle. The needle body is heated, and the heated needle body is depressurized by conducting heat according to the opening of the pressure relief passage; The observation focus of the needle body is adjusted according to the heat insulation separation height; The needle insertion position is set according to the preset tilt direction and the heat insulation separation height, and the needle body is subjected to pre-insertion oscillation according to the decaying acceleration of the pre-oscillation. Monitor the needle's condition according to the observed focal length.

[0006] Further, determining the preset tilt direction of the needle body's support and the heat insulation separation height based on the curvature model includes: Scan the surface of the acupuncture site and obtain the curvature model; The normal vector of the needle insertion point is determined based on the curvature model. The normal vector of the needle puncture point is used as the preset tilt direction; The insulation separation height is determined based on the radius of curvature of the curvature model.

[0007] Furthermore, the heat insulation separation height is the minimum distance between the heating position of the needle body and the acupuncture point.

[0008] Further, determining the decay acceleration of the preparatory oscillation of the needle body along the preset tilt direction based on the physiological micro-motion amplitude includes: Obtain the amplitude of the physiological micro-movement; The amplitude of the physiological micro-movement is compared with the preset amplitude; If the physiological micro-motion amplitude is greater than or equal to the preset amplitude, then the decay acceleration of the preparatory oscillation of the needle body along the preset tilt direction is increased.

[0009] Furthermore, the decaying acceleration is the ratio of the initial oscillation rate at the start of the preparatory oscillation applied to the needle body along the preset tilt direction to the oscillation duration of the preparatory oscillation.

[0010] Furthermore, the physiological micro-motion amplitude is the displacement component of the total displacement of the acupuncture point within a unit monitoring time in the direction of the normal vector.

[0011] Further, determining the opening degree of the pressure relief path for conducting heat and relieving pressure to the environment surrounding the needle body based on the aforementioned positive tilt deviation angle includes: Obtain the positive tilt deviation angle; The positive tilt deviation angle is compared with the preset deviation angle; If the alignment tilt deviation angle is greater than or equal to the preset deviation angle, then the opening degree of the heat conduction and pressure relief is increased.

[0012] Furthermore, the positive tilt deviation angle is the acute angle between the axis of the needle body and the direction of the normal vector.

[0013] Furthermore, the preparatory oscillation process includes: After setting the needle insertion position, apply preparatory oscillation along the preset tilt direction according to the initial oscillation rate; The oscillation rate is reduced by the decaying acceleration until the needle stops.

[0014] Furthermore, the increase in the decay acceleration is determined based on the difference between the physiological micro-motion amplitude and the preset amplitude.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The method of the present invention obtains the curvature model and physiological micro-motion amplitude of the surface of the acupuncture site. Since the acupuncture site in Mongolian medicine warm needling therapy is often an area with irregular surface curvature, and is accompanied by breathing or muscle tremors causing continuous micro-displacement deviations at the acupuncture point, this leads to needle deviation during insertion due to physiological micro-motions or surface tilt, affecting acupuncture accuracy. By determining the preset tilt direction and heat insulation separation height of the needle support based on the curvature model, the needle is aligned along the normal direction of the target tissue, avoiding the deviation in the insertion angle caused by the curvature of the surface at the insertion point, thus improving accuracy. The stability and positioning accuracy of the needle insertion process have been improved. By adjusting the decay acceleration of the preparatory oscillation according to the physiological micro-motion amplitude, the needle body oscillates in the pre-set tilt direction at the needle insertion front, reducing the deviation during actual needle insertion. By detecting the alignment tilt deviation angle of the needle body, the opening of the heat conduction and pressure relief path is dynamically adjusted. When the deviation angle increases, the pressure relief opening is increased to accelerate the diffusion of heat around the needle body, avoiding local hot spots or heat accumulation caused by uneven heat conduction due to needle body tilt. The observation focal length is adjusted according to the heat insulation separation height to monitor the needle body status and ensure the needle insertion orientation, thereby improving the adjustment accuracy of the needle body heat insulation.

[0016] Furthermore, the method of the present invention obtains the physiological micro-motion amplitude and determines the decaying acceleration of the preparatory oscillation of the needle body along the preset tilt direction. Due to the patient's voluntary or involuntary physiological activities, such as respiratory fluctuations and muscle fasciculations, dynamic changes in the tissue around the needle tip can easily cause needle body shaking or even puncture injury. By introducing a preparatory oscillation mechanism with controllable decay characteristics, the movement trend of the local tissue is actively simulated and adapted before needle insertion. The relative displacement impact between the needle body and the tissue is reduced by using dynamic compensation, which significantly improves the stability of the needle body during the insertion process. The needle body vibration is flexibly terminated by decaying acceleration to avoid rebound deviation caused by sudden cessation of the needle body, ensuring that the needle body remains aligned along the normal direction of the target tissue at the end of the oscillation, providing stable initial conditions for smooth needle insertion.

[0017] Furthermore, the method of the present invention detects the alignment and tilt deviation angle of the needle and adjusts the opening of the heat conduction and pressure relief path according to the deviation angle. Since traditional warm needles often cause uneven heat conduction due to uneven contact between the needle and the skin or gas retention during the heating process, resulting in local hot spots or heat accumulation, it is easy to cause epidermal burns or excessive heat stimulation. By setting the heat conduction and pressure relief, when there is a large tilt deviation of the needle, the opening of the pressure relief path is automatically increased, which promotes air flow around the needle and the discharge of excess heat, effectively balancing the temperature field distribution around the needle.

[0018] Furthermore, the method of the present invention adjusts the observation focal length based on the height of the heat insulation separation from the skin. Since it is necessary to monitor the distance between the needle and the skin and the state of the heated area in real time during actual operation, the method uses the height of the heat insulation separation from the skin as the focusing basis of the optical monitoring system to achieve clear imaging of the interface between the heated position of the needle and the skin, which facilitates the judgment of the needle state and the heat insulation effect.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The figures shown are, respectively, an overall flowchart, a schematic diagram of the needle body heat insulation protection device, a schematic diagram of the heat insulation pad, and a flowchart for determining the attenuation acceleration, all according to embodiments of the present invention. An embodiment of the present invention provides an adjustable needle body heat insulation protection method for Mongolian medicine warm needling therapy, comprising: Obtain the curvature model and physiological micro-motion amplitude of the surface of the acupuncture site, and detect the orthogonal tilt deviation angle of needle body 1; The preset tilt direction and heat insulation separation height of the support 3 of the needle body 1 are determined according to the curvature model. The decay acceleration of the preparatory oscillation of the needle body 1 along the preset tilt direction is determined based on the physiological micro-motion amplitude. The opening degree of the pressure relief passage for conducting heat and relieving pressure to the environment around the needle body 1 is determined according to the aforementioned positive tilt deviation angle. The needle body 1 is heated, and the heated needle body 1 is depressurized by conducting heat according to the opening of the pressure relief passage; The observation focus of the needle body 1 is adjusted according to the heat insulation separation height; The needle body 1 is positioned according to the preset tilt direction and the heat insulation separation height, and the needle body 1 is subjected to pre-insertion oscillation according to the decaying acceleration of the pre-oscillation. Monitor the status of needle body 1 according to the observed focal length.

[0025] Specifically, the physiological micro-motion amplitude is monitored by a high frame rate camera with a monitoring time of 1 second. The displacement of the needle point in the normal vector direction is tracked. For example, if the recorded displacement is 0.5 mm, then 0.5 mm is the physiological micro-motion amplitude.

[0026] Specifically, the positive tilt deviation angle is captured by an industrial camera to obtain an image of needle body 1, the axis of needle body 1 is determined by straight line fitting, and the fitted axis of needle body 1 is compared with the normal vector in the curvature model.

[0027] Specifically, the heat insulation protection device for the needle body 1 based on the adjustable needle body 1 heat insulation protection method includes: Needle body 1, bracket 3 for adjusting the preset tilt direction and heat insulation separation height, heat insulation pad 5 connected to needle body 1, observation window, heater connected to needle body 1 for heating needle body 1, annular slit channel 2 set on the side of bracket 3 near needle body 1 for blowing hot air to needle body 1, and miniature drive motor 4 connected to needle body 1 for pre-vibration of needle body 1. An electromagnetic valve is installed in the annular slit channel 2 to control the opening of the pressure relief passage for heat conduction and pressure relief. A heater is connected to the annular slit channel 2 to heat the gas in the annular slit channel 2. The heat insulation pad 5 is made of medical-grade silicone on the side that comes into contact with the human body, and ceramic fiber or transparent microcrystalline glass is used on the side that is away from the skin. The heat insulation pad 5 is round or oval in shape and has a through hole 6 in the center.

[0028] Specifically, the vibration distance for the preparatory oscillation should not exceed 3 mm.

[0029] Specifically, the observation focal length refers to the focusing distance F of the monitoring camera within the observation window on the needle body 1. In this embodiment, a 5-megapixel monitoring camera is used to monitor the needle body 1. The relationship between the distance F and the heat insulation separation height H is F=H+C, where C is a constant used to compensate for lens offset (C is set to 5mm to compensate for lens offset). If the heat insulation separation height is 7mm, the focal length is adjusted to 12mm.

[0030] Specifically, the state of needle body 1 includes the insertion depth, the displacement of needle body 1, whether needle body 1 is bent, and the relative position of needle body 1 and through hole 6.

[0031] In practice, the method of this invention obtains the curvature model and physiological micro-motion amplitude of the acupuncture site surface. Since the acupuncture sites in Mongolian warm needling therapy are often areas with irregular surface curvature, and are accompanied by breathing or muscle tremors causing continuous micro-displacement deviations at the acupuncture point, this can lead to needle deviation during insertion due to physiological micro-motion or surface tilt, affecting acupuncture accuracy. By determining the preset tilt direction of the needle support and the heat-insulating separation height based on the curvature model, the needle is aligned along the normal direction of the target tissue, avoiding insertion angle deviations caused by the curvature of the insertion site surface, thus improving the insertion process. Stability and positioning accuracy; by adjusting the decay acceleration of the preparatory oscillation according to the physiological micro-motion amplitude, the needle body oscillates in the pre-set tilt direction at the needle insertion front, reducing the deviation during actual needle insertion; by detecting the alignment tilt deviation angle of the needle body, the opening of the heat conduction and pressure relief path is dynamically adjusted. When the deviation angle increases, the pressure relief opening is increased to accelerate the diffusion of heat around the needle body, avoiding local hot spots or heat accumulation caused by uneven heat conduction due to needle body tilt; the observation focal length is adjusted according to the heat insulation separation height to monitor the needle body status and ensure the needle insertion orientation, thereby improving the adjustment accuracy of the needle body heat insulation.

[0032] Specifically, determining the preset tilt direction and heat insulation separation height of the support 3 of the needle body 1 based on the curvature model includes: Scan the surface of the acupuncture site and obtain the curvature model; The normal vector of the needle insertion point is determined based on the curvature model. The normal vector of the needle puncture point is used as the preset tilt direction; The insulation separation height is determined based on the radius of curvature of the curvature model.

[0033] Specifically, the curvature model is obtained by scanning with a 3D structure scanner. In this embodiment, the ArtecEva scanner is selected, with a scanning distance of 10cm to 20cm. After scanning, the point cloud data of the rear surface is generated, and the curvature radius and normal vector of the needle point are calculated.

[0034] Specifically, the heat insulation separation height is the minimum distance between the heating position of the needle body 1 and the acupuncture point.

[0035] Specifically, the insulation separation height H is set according to the radius of curvature R, including: If R < 30 mm, then H = 10 mm; If 30mm ≤ R < 60mm, then H = 7mm; If R ≥ 60 mm, then H = 5 mm.

[0036] Specifically, determining the decay acceleration of the preparatory oscillation of the needle body 1 along the preset tilt direction based on the physiological micro-motion amplitude includes: Obtain the amplitude of the physiological micro-movement; The amplitude of the physiological micro-movement is compared with the preset amplitude; If the physiological micro-motion amplitude is greater than or equal to the preset amplitude, then the decay acceleration of the preparatory oscillation of the needle body 1 along the preset tilt direction is increased.

[0037] Specifically, the decaying acceleration is the ratio of the initial oscillation rate at the start of the preparatory oscillation applied to the needle body 1 along the preset tilt direction to the oscillation duration of the preparatory oscillation.

[0038] Specifically, the increase in decay acceleration is determined based on the difference between the physiological micro-motion amplitude and the preset amplitude.

[0039] Specifically, when the acupuncture site is on the back and the heat insulation pad 5 is 3mm thick, the general range of the preset amplitude is [0.5mm, 4mm], and the preferred embodiment of the preset amplitude is 2mm; when the acupuncture site is on the knee joint and the heat insulation pad 5 is 5mm thick, the general range of the preset amplitude is [0.2mm, 0.5mm], and the preferred embodiment of the preset amplitude is 0.3mm.

[0040] Those skilled in the art will understand that the selectable range of the preset amplitude and the preferred embodiment provided in this embodiment are the values ​​that best achieve the technical problem solved by the technical solution of the present invention, when the surface of the acupuncture site is the back and the thickness of the heat insulation pad 5 is 3mm, or when the surface of the acupuncture site is the knee joint and the thickness of the heat insulation pad 5 is 5mm. In actual application or experiment, those skilled in the art can make adaptive adjustments to the preset amplitude according to the actual application environment and application scenario.

[0041] In practice, the initial oscillation rate is set to 8 mm / s and the oscillation duration is 2 s. For every 0.1 mm difference between the physiological micro-motion amplitude and the preset amplitude, the decay acceleration increases by 0.1 mm / s². For example, if the acupuncture site is on the back, and the difference between the physiological micro-motion amplitude and the preset amplitude is 0.3 mm, then the decay acceleration increases to 4 mm / s² + 0.1 mm / s² × 3 = 4.3 mm / s².

[0042] In practice, the method of this invention obtains the physiological micro-motion amplitude and determines the decaying acceleration of the preparatory oscillation of the needle body along the preset tilt direction. Due to the patient's voluntary or involuntary physiological activities, such as respiratory fluctuations and muscle fasciculations, dynamic changes in the tissue around the needle tip can easily cause needle body shaking or even puncture injury. By introducing a preparatory oscillation mechanism with controllable decay characteristics, the movement trend of local tissue is actively simulated and adapted before needle insertion. The relative displacement impact between the needle body and the tissue is reduced by using dynamic compensation, which significantly improves the stability of the needle body during insertion. The decaying acceleration gently terminates the needle body vibration, avoiding rebound deviation caused by sudden cessation of the needle body. This ensures that the needle body remains aligned along the normal direction of the target tissue at the end of the oscillation, providing stable initial conditions for smooth needle insertion.

[0043] Specifically, the physiological micro-motion amplitude is the displacement component of the total displacement of the acupuncture point in the direction of the normal vector within a unit monitoring time.

[0044] Specifically, determining the opening of the pressure relief passage for conducting heat and relieving pressure to the environment surrounding the needle body 1 based on the aforementioned tilt deviation angle includes: Obtain the positive tilt deviation angle; The positive tilt deviation angle is compared with the preset deviation angle; If the alignment tilt deviation angle is greater than or equal to the preset deviation angle, then the opening degree of the heat conduction and pressure relief is increased.

[0045] Specifically, the alignment tilt deviation angle is the acute angle between the axis of the needle body 1 and the direction of the normal vector.

[0046] Specifically, in the case of a circular heat insulation pad 5 with a thickness of 3mm and a through hole 6 with a diameter of 5mm in the center, the general range of the preset deviation angle is [0.5°, 3°], and the preferred embodiment of the preset deviation angle is 1.2°.

[0047] Those skilled in the art will understand that the range of preset deviation angles and preferred embodiments provided in this embodiment are the values ​​that best address the technical problem solved by the present invention, under the condition that the circular heat insulation pad 5 has a thickness of 3 mm and a through hole 6 with a diameter of 5 mm is opened in the center. In actual applications or experiments, those skilled in the art can make adaptive adjustments to the preset deviation angles according to the actual application environment and application scenario.

[0048] In practice, if the difference between the positive tilt deviation angle and the preset deviation angle exceeds 0.1°, the opening of the heat conduction pressure relief will increase by 5%. For example, if the opening of the heat conduction pressure relief is 0 and the difference between the positive tilt deviation angle and the preset deviation angle is 1°, the opening of the heat conduction pressure relief will increase to 50%.

[0049] In practice, the method of the present invention detects the alignment and tilt deviation angle of the needle and adjusts the opening of the heat conduction and pressure relief path according to the deviation angle. Because traditional warm needles often cause uneven heat conduction due to uneven contact between the needle and the skin or gas retention during the heating process, resulting in local hot spots or heat accumulation, which can easily cause epidermal burns or excessive heat stimulation; by setting the heat conduction and pressure relief, when there is a large tilt deviation of the needle, the opening of the pressure relief path is automatically increased, which promotes air flow around the needle and the discharge of excess heat, effectively balancing the temperature field distribution around the needle.

[0050] Specifically, the preparatory oscillation process includes: After setting the insertion position of the needle body 1, the needle body 1 is subjected to preparatory oscillation along the preset tilt direction according to the initial oscillation rate. The oscillation rate is reduced according to the decay acceleration until the needle body 1 stops.

[0051] In practice, the method of the present invention adjusts the observation focal length based on the height of the heat insulation separation from the skin. Since it is necessary to monitor the distance between the needle and the skin and the state of the heated area in real time during actual operation, the heat insulation separation height is used as the focusing basis of the optical monitoring system to achieve clear imaging of the interface between the heated position of the needle and the skin, which facilitates the judgment of the needle state and the heat insulation effect.

[0052] Example 1:

[0053] The heat insulation protection device of the needle body 1 is made of ceramic fiber material to form a circular heat insulation pad 5 with a thickness of 3mm and a through hole 6 with a diameter of 5mm in the center; the bracket 3 adopts a composite structure of aluminum alloy and medical plastic, which supports the vertical adjustment range of 0~30mm and the angle adjustment range of 0~45°; the observation window is made of high borosilicate glass.

[0054] In this embodiment, for the acupuncture site on the back, the adjustable needle body heat insulation protection is as follows: the device is fixed to the acupuncture site on the back, and the surface curvature model and physiological micro-motion amplitude of the acupuncture site on the back are detected; the angle is adjusted to 15° and the height is 10mm; a warm needle is inserted, and the heating section of the needle body is isolated from the skin through a heat insulation pad, and the status of the needle body is monitored through an observation window.

[0055] Example 2:

[0056] For the knee joint area, an oval-shaped heat insulation pad with a central through hole of 6mm is selected; the support is adjusted to a height of 20mm and an angle of 30° to fit the curvature of the knee joint.

[0057] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
