Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, this application relates to a portable traditional Chinese medicine handheld acupuncture device. Background Technology

[0002] Press-needle therapy, as an important practical form of TCM skin region theory, is increasingly popular in pain management and adjunctive treatment of chronic diseases due to its advantages of non-invasive penetration and continuous stimulation. Existing intelligent press-needle systems generally adopt a knowledge-based recommendation architecture: by constructing a structured TCM meridian database (covering the coordinates of 361 standard acupoints and their indications), a rule-based acupoint matching engine is triggered by the user's input of symptom descriptions; some advanced systems introduce electronic meridian map overlay technology, which uses a camera to capture the contours of the body surface, and then aligns the preset meridian template with the user's body image through affine transformation to generate a basic acupoint distribution heatmap.

[0003] Such systems output standardized treatment plans through preset acupuncture treatment duration / number of needles parameters (usually graded according to disease type) and guide the needle placement position with vibration feedback or visual projection; however, with the increasing demand for portable diagnosis and treatment scenarios, this recommendation paradigm that relies on static knowledge bases and rigid mapping rules is gradually showing adaptive bottlenecks in key aspects such as human anatomical variations and dynamic optimization of treatment parameters.

[0004] Traditional press needle systems rely on static knowledge bases and rigid mapping rules, which expose three major defects when faced with human anatomical variability and respiratory rhythm interference: insufficient acupoint positioning accuracy, lack of dynamic adaptability, and blank safety verification mechanism. This results in poor treatment response stability and low operation efficiency. Therefore, a portable handheld press needle device for traditional Chinese medicine is proposed to solve this problem. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a portable handheld acupuncture device for traditional Chinese medicine is provided. This technical solution solves the problems mentioned in the background.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] This application provides a portable handheld acupuncture device for traditional Chinese medicine, comprising:

[0008] The press needle housing has a press button at its top;

[0009] The replacement die is fixedly connected to the bottom of the inner side of the presser housing, and multiple presser plates are movably engaged inside the replacement die;

[0010] The pressing structure is fixedly connected to the top of the inner side of the press needle housing, and the top end of the pressing structure is fixedly connected to the pressing button, while the bottom end is slidably connected to the inner side of the top end of the replacement die.

[0011] The development control board is fixedly connected to the inner wall of one side of the press needle shell, and the development control board is electrically connected to the pressing structure. It is used to receive the acupoint set, compare the acupoint set with the actual coordinate data, and output a correction signal when the deviation exceeds the preset threshold.

[0013] Acquire visible light and thermal images of the user's body surface, and perform spatial coordinate registration between the two;

[0014] Thermal gradient compensation is performed on the visible light image using temperature distribution data from thermal imaging, generating a surface topology mapping containing spatial coordinates and temperature gradients.

[0015] The gradient magnitude of the topological mapping of the body surface is calculated to generate a set of edge points. The edge points are then slid along a preset meridian path with a step size of the same body size. Continuous segments with curvature changes between adjacent edge points that do not exceed a preset curvature threshold are merged to generate a connected skeleton map.

[0017] Select any extreme point in the same meridian acupoint group as the target acupoint, calculate the vector angle between it and the two adjacent extreme points, and delineate a preset anatomical radius selection area with the target acupoint as the center. The extreme points in the same meridian acupoint group within the aggregation area generate a convex polygon.

[0018] If the included angle of the vector is less than the preset included angle threshold and the sum of the interior angles of the convex polygon is less than the preset deviation value, then the target acupoint is included in the acupoint set; otherwise, along the curvature gradient and towards the nearest acupoint in the preset meridian path, a compensation point is generated at a distance of a preset multiple of the body inch and included in the acupoint set, and the acupoint set is sent to the development control board.

[0019] Preferably, the needle press housing includes a front half and a rear half. A control screen and a power button are provided on the outer side of the front half. A camera module is fixedly connected to the inner wall of one side of the rear half.

The development control board is electrically connected to the vibration motors. The vibration motors are used to generate vibrations for the user after receiving a correction signal, and to move the press needle housing to the side where the vibration is generated.

[0021] Preferably, a telescopic spring is fixedly connected to the bottom end of the pressing structure, and a push cylinder is fixedly connected to the bottom end of the telescopic spring. The outer side of the push cylinder is slidably connected to the inner wall of the replacement core, and the bottom end of the push cylinder is movably abutting against the uppermost press pin.

[0023] Preferably, after the remote device generates the body surface topology map, it also includes a respiratory phase compensation mechanism:

[0024] Based on the time-series temperature data from thermal imaging, the temperature fluctuation frequency of the xiphoid process region is extracted.

[0025] The respiratory cycle phase angle is determined based on the peak interval of the temperature fluctuation frequency, and the maximum inspiratory phase and the maximum expiratory phase are marked.

[0026] Locate the xiphoid process projection point in the visible light image of the maximum inspiratory phase, and then locate the same xiphoid process projection point again in the visible light image of the maximum expiratory phase. Calculate the displacement vectors of the two projection points as the respiratory compensation vector.

[0027] The body surface topology mapping is compared with the preset meridian paths to divide different meridian zones;

[0028] Based on this respiratory compensation vector, the local compensation parameters of each meridian area are converted according to the same body size ratio, and then superimposed on the spatial coordinates of the body surface topological mapping.

[0029] Preferably, the remote device also includes a treatment safety strategy generated based on the acupoint set, specifically including:

[0030] The confidence score is calculated based on the vector angle between each acupoint in the acupoint set and the interior angle of the convex polygon.

[0031] When the confidence score is lower than the lower limit of the preset confidence threshold interval, a forbidden acupuncture zone is marked at the corresponding acupoint coordinates.

[0032] When the confidence score is higher than the upper limit of the preset confidence threshold range, standard acupuncture parameters are invoked, including acupuncture duration and number of needles used.

[0033] When the confidence score is within the preset confidence threshold range, the acupuncture treatment duration is multiplied by the dynamic decay coefficient based on the confidence score to generate the actual acupuncture treatment duration;

[0034] The forbidden acupuncture zone markers, actual acupuncture treatment duration, and standard acupuncture parameters are associated with acupoint coordinates to output a structured acupoint coordinate file containing a three-level safety strategy.

[0035] Preferably, the formula for calculating the confidence score is:

[0040] The body shape compensation coefficient is determined by comparing the body shape index value with a preset compensation coefficient reference table; the local density influence factor is calculated based on the subcutaneous fat thickness measurement value.

[0041] The body size compensation coefficient is multiplied by the local density influence factor to generate a comprehensive calibration coefficient, which is then multiplied by the confidence score to generate a calibrated confidence score.

[0042] Preferably, the formula for calculating the local density influence factor is:

[0043] ;

[0044] In the formula, As a local density influence factor, The fat-density attenuation coefficient. This is a measurement of subcutaneous fat thickness. This is the thickness compensation coefficient. This represents the critical fat thickness.

[0045] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0046] This application dynamically integrates anatomical landmarks (visible light) and subcutaneous metabolic hotspots (thermal imaging) by registering visible light images and thermal images with spatial coordinates, thus overcoming the bottleneck of static knowledge base adaptability to anatomical variability. It uses temperature distribution data from thermal imaging images to perform thermal gradient compensation on visible light images, generating a body surface topological mapping containing spatial coordinates and temperature gradients, thus solving the defect of insufficient acupoint positioning accuracy.

[0047] This application extracts the temperature fluctuation frequency of the xiphoid process region from time-series temperature data based on thermal imaging, determines the respiratory cycle phase angle, and calculates the respiratory compensation vector, effectively offsetting the periodic displacement of the body surface caused by respiratory movement, and ensuring that the meridian coordinates are dynamically aligned with the actual anatomical position in the time dimension.

[0048] This application calculates the vector angle between the target acupoint and adjacent extreme points and aggregates the extreme points to generate a convex polygon. It uses a preset angle threshold and deviation value to perform dual verification of the acupoint spatial topology. The vector angle constrains the rationality of the meridian direction, and the interior angle of the convex polygon confirms the consistency of the group anatomy. Based on the confidence score, it dynamically associates the forbidden acupuncture area or adjusts the acupuncture parameters, thereby reducing the risk of misjudgment. Attached Figure Description

[0053] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0054] In existing technologies, press-needle therapy, as an important practical form of traditional Chinese medicine's skin meridian theory, is increasingly popular in pain management and adjunctive treatment of chronic diseases due to its advantages of non-invasive penetration and continuous stimulation. Current intelligent press-needle systems generally adopt a knowledge-based recommendation architecture: by constructing a structured TCM meridian database and combining it with user-inputted symptom descriptions, a rule-based acupoint matching engine is triggered. Some advanced systems introduce electronic meridian map overlay technology, using a camera to capture the body surface contour and then aligning a preset meridian template with the user's body image through affine transformation to generate a basic acupoint distribution heatmap. These systems output standardized treatment plans through preset acupuncture duration or intensity parameter tables and guide the needle placement using vibration feedback or visual projection. However, in portable medical scenarios, the recommendation paradigm relying on static knowledge bases and rigid mapping rules struggles to cope with the variability of human anatomy and the dynamic optimization needs of treatment parameters, resulting in insufficient acupoint positioning accuracy, lack of dynamic adaptability, and a lack of safety verification mechanisms.

[0055] To address the aforementioned issues, this study analyzes the correlation between body surface temperature distribution and visible light images, explores the synergistic effect of thermal gradient compensation and respiratory phase compensation, and further considers the continuity characteristics of meridian pathways. It proposes a method for dividing acupoint groups based on curvature extreme point clustering, and combines this with a convex polygon verification mechanism to achieve dynamic correction of acupoint locations. Ultimately, this results in a technical solution that includes spatial coordinate correction and safety strategy generation, solving the positioning deviation problem caused by rigid mapping in traditional systems.

[0056] Reference Figure 1-2 As shown, this application proposes a portable handheld acupuncture device for traditional Chinese medicine, comprising:

[0057] The press needle housing 1 has a press button 2 at its top;

[0058] Replacement core 3 is fixedly connected to the bottom of the inner side of the presser housing 1, and multiple presser plates are movably engaged inside the replacement core 3;

[0059] The pressing structure 4 is fixedly connected to the top of the inner side of the presser housing 1, and the top end of the pressing structure 4 is fixedly connected to the pressing button 2, while the bottom end is slidably connected to the inner side of the top end of the replacement tube 3.

[0060] It should be noted that when the user triggers the press button 2, it drives the fixedly connected press structure 4 to move downward, compressing the telescopic spring at its bottom end. The elastic deformation of the telescopic spring pushes the push cylinder 12, which is fixedly connected to it, to slide along the inner wall of the replacement tube 3. After the bottom end of the push cylinder 12 contacts the uppermost press needle, the stacked needles move downward as a whole through vertical pressure transmission. When the lowermost press needle reaches the outlet of the cap 14, it disengages from the snap-fit ​​groove of the replacement tube 3 to pierce the human skin at the set piercing depth. After the pressing action ends, the restoring force of the telescopic spring drives the push cylinder 12 to automatically return to the initial position within 0.3 seconds, reserving the stroke for the next press.

[0061] A central control board 5 is developed and fixedly connected to the inner wall of one side of the press needle housing 1. The central control board 5 is electrically connected to the pressing structure 4 and is used to receive the acupoint set. Based on the acupoint set and the actual coordinate data, a correction signal is output when the deviation exceeds the preset error threshold. Among them, anatomical studies have shown that when the acupoint center point offset is >5mm, the stimulation effectiveness decreases by >30%. Therefore, the preset error threshold can be ±5mm.

[0062] It should be noted that the outer shell 1 of the press needle device serves as an ergonomic grip carrier, integrates the electronic module, and its front half shell 6 has a control screen 8 embedded in it to display the coordinates of the acupoints; the replacement core 3 is used for the modular needle storage unit, with 10-15 press needle plates inside; the pressing structure 4 is used to convert the linear motion of the pressing button 2 into the propulsive force of the press needle plates.

[0063] To further explain, the usage process of this TCM handheld press needle device is as follows: the user touches the press button 2, which drives the press structure 4 to press down the push cylinder 12 to push the top press needle plate, and the transmission causes the bottom press needle plate to detach from the screw cap 14 and pierce the human skin. The central control board 5 synchronously receives the real-time coordinates of the needle tip, compares it with the most suitable acupoint coordinates, and if the deviation exceeds the preset error threshold, the vibration motor 11 is activated.

[0064] Remote devices are used for:

[0065] Acquire visible light and thermal images of the user's body surface, and perform spatial coordinate registration between the two;

[0066] Thermal gradient compensation is performed on the visible light image using temperature distribution data from thermal imaging, generating a surface topology mapping containing spatial coordinates and temperature gradients.

[0067] The gradient magnitude of the topological mapping of the body surface is calculated to generate a set of edge points. The edge points are then slid along a preset meridian path with a step size of the same body size. Continuous segments with curvature changes between adjacent edge points that do not exceed a preset curvature threshold are merged to generate a connected skeleton map.

[0068] A fixed-multiple body inch band buffer is constructed along the centerline of the connected skeleton map. Curvature extrema points within this band buffer are extracted and clustered into acupoint groups of the same meridian according to a preset angle threshold. Here, body inch is a unique body surface positioning measurement unit in traditional Chinese medicine. Its core feature is individualized relative length. 1 inch is the distance between the outer edges of the two transverse creases on the dorsal side of the middle phalanx (proximal interphalangeal joint) of the user's own middle finger. When body inch scanning is not performed, the default body inch can be 15mm, and the fixed multiple can be 0.7.

[0069] It should be noted that, according to studies in meridian anatomy, the normal range of meridian curvature variation is as follows: Therefore, the preset curvature threshold can be taken as follows: This covers anatomical variation tolerance; clinical practice in Traditional Chinese Medicine has shown that the angle at acupoints... When tissue tension is abnormal, the preset included angle threshold can be set to... ;

[0070] Select any extreme point in the same meridian acupoint group as the target acupoint, calculate the vector angle between it and the two adjacent extreme points, and delineate a preset anatomical radius selection area with the target acupoint as the center. The extreme points in the same meridian acupoint group within the aggregation area generate a convex polygon.

[0071] If the included angle of the vector is less than the preset included angle threshold and the sum of the interior angles of the convex polygon is less than the preset deviation value, then the target acupoint is included in the acupoint set; otherwise, along the curvature gradient and towards the nearest acupoint in the preset meridian path, a compensation point is generated at a distance of a preset multiple of the body inch and included in the acupoint set, and the acupoint set is sent to the development control board 5; where the preset multiple can be 0.5, and half the body inch is the minimum safe adjustment unit;

[0072] It should be noted that the theoretical sum of the interior angles of a convex polygon is... Measured value deviation The system indicates that the spatial topology of the acupoint group is abnormal. Therefore, the preset deviation value can be ±10% of the theoretical value of the interior angles, where n is the number of sides of the convex polygon (equivalent to the number of vertices) and is a dimensionless integer.

[0073] In an optional embodiment, the needle press housing 1 includes a front half housing 6 and a rear half housing 7. A control screen 8 and a power button 9 are provided on the outer side of the front half housing 6. A camera module 10 is fixedly connected to the inner wall of one side of the rear half housing 7. The development control board 5 is electrically connected to the control screen 8, the power button 9 and the camera module 10 respectively. The development control board 5 collects real-time coordinate data through the camera module 10.

[0074] The split structure of the front half shell 6 and the rear half shell 7 is achieved by snap-fit, which facilitates the installation and maintenance of internal components; the control screen 8 is an interactive device used to display the operation interface and acupoint positioning information; the power button 9 is a physical button that controls the power supply of the device.

[0075] It should be noted that the camera module 10 has a resolution of ≥1080P, and the smallest acupoint recognition unit needs to cover a 2×2mm area. 1080P can provide an accuracy of 0.5mm / pixel. The camera module 10 is equipped with light source enhancement, specifically 850nm infrared illumination and visible light dual modes, to enhance the imaging of blood vessels and fascia layers. The real-time coordinate data sampling frequency of the camera module 10 is 10Hz, which is based on the fact that the frequency of human hand tremor is ≤5Hz. 10Hz sampling can capture 95% of displacement fluctuations.

[0076] For example, the central control board 5 can store the acupoint coordinate set of 10 consecutive treatments by the same user and calculate the standard deviation of each acupoint coordinate point: if the standard deviation is less than 1mm, a personalized acupoint template will be automatically generated; if the standard deviation is greater than 2mm, a prompt "Please recalibrate posture" will be displayed on the control screen 8.

[0077] Through the above technical solution, this application improves the dynamic adaptability of acupoint positioning by using the built-in camera module 10 and real-time coordinate acquisition mechanism, ensuring that the acupuncture operation is accurately matched with the user's body surface characteristics.

[0078] In an optional embodiment, four vibration motors 11 arranged in a circumferentially spaced manner are fixedly installed on the outer side of the presser housing 1. The development control board 5 is electrically connected to the vibration motors 11. The vibration motors 11 are used to generate vibrations for the user after receiving a correction signal, so that the user moves the presser housing to the side where the vibration is generated.

[0079] Specifically, the vibration intensity generated by the vibration motor 11 is variable, and the vibration duration is adjustable from 0.5 to 2 seconds; the development control board 5 calculates the deviation vector between the actual coordinates and the target acupoint and decomposes it into horizontal and vertical components; if the absolute value of the horizontal component exceeds the preset error threshold, the vibration intensity is set to k times the absolute value of the horizontal component, k=0.25G / mm, where G is the acceleration due to gravity.

[0080] Through the above technical solution, this application realizes real-time correction guidance without visual dependence, which effectively improves the reliability of acupoint positioning operation in complex environments. The directional transmission characteristics of vibration signals allow users to perceive and adjust the direction without interrupting the acupuncture action, shortening the time required for positioning calibration.

[0081] In an optional embodiment, a telescopic spring is fixedly connected to the bottom end of the pressing structure 4, and a push cylinder 12 is fixedly connected to the bottom end of the telescopic spring. The outer side of the push cylinder 12 is slidably connected to the inner wall of the replacement core 3, and the bottom end of the push cylinder 12 is movably abutting against the uppermost push pin.

[0082] Specifically, when the user triggers the button 2, it drives the pressing structure 4 to move downward, thereby compressing the telescopic spring and causing the push cylinder 12 to slide downward along the inner wall of the replacement core 3 through its elastic deformation. After the bottom end of the push cylinder 12 contacts the uppermost snap pin, it continuously applies vertical pressure to make the lowermost snap pin disengage from the snap-fit ​​state of the replacement core 3 and connect with the human skin. After the pressing action ends, the restoring force of the telescopic spring drives the push cylinder 12 to return to the initial position, providing a preparatory stroke for the next pressing.

[0083] Through the above technical solution, this application realizes the smooth transmission and automatic reset function of the pressing action, effectively improving the stability and continuity of the press needle pushing process. Through the dual optimization of mechanical buffering and low friction, the problem of needle jamming caused by rigid contact in traditional devices is solved, ensuring the uniformity of force applied with each press and improving the safety and reliability of the treatment operation.

[0084] In an optional embodiment, a needle storage chamber 13 is fixedly installed on the bottom inner side of the presser housing 1, and a replacement core 3 is slidably installed on the inner side of the needle storage chamber 13. The bottom end of the needle storage chamber 13 extends to the outer side of the presser housing 1, and a screw cap 14 is threadedly connected to the outer side of the bottom end of the needle storage chamber 13. The bottom end of the screw cap 14 is provided with a presser plate outlet.

[0085] Specifically, the needle reservoir 13 is fixedly installed on the bottom of the inner side of the outer shell to form an independent storage space. After the replacement needle 3 is inserted into the needle reservoir 13, the cap 14 is fixed by rotating the screw thread. The bottom of the cap 14 is provided with a needle clip outlet, which makes it easy for the needle clip to detach from the replacement needle 3 and come into contact with the human skin. When the replacement needle 3 needs to be replaced, the cap 14 is rotated open, and the replacement needle 3 slides along the needle reservoir 13 to the outlet position under the action of gravity. The needle clip slides out through the outlet in a directional manner.

[0086] Through the above technical solution, this application realizes centralized storage and controllable release of the press pin, reducing the risk of contamination during replacement operations. At the same time, the combination design of sliding installation and threaded connection improves equipment maintenance efficiency and ease of operation.

[0087] In an optional embodiment, after the remote device generates the body surface topology map, it also includes a respiratory phase compensation mechanism:

[0088] Based on the time-series temperature data from thermal imaging, the temperature fluctuation frequency of the xiphoid process region is extracted.

[0089] The respiratory cycle phase angle is determined based on the peak interval of the temperature fluctuation frequency, and the maximum inspiratory phase and the maximum expiratory phase are marked.

[0090] Locate the xiphoid process projection point in the visible light image of the maximum inspiratory phase, and then locate the same xiphoid process projection point again in the visible light image of the maximum expiratory phase. Calculate the displacement vectors of the two projection points as the respiratory compensation vector.

[0091] The body surface topology mapping is compared with the preset meridian paths to divide different meridian zones;

[0092] Based on this respiratory compensation vector, the local compensation parameters of each meridian area are converted according to the proportion of the same body size, and then superimposed on the spatial coordinates of the body surface topological mapping.

[0093] Specifically, the meridian zones are as follows: The core trunk zone corresponds to the Ren and Du meridians, with an attenuation coefficient of 0.9-1.0. Significant chest and abdominal displacement during respiration requires near-full compensation. The proximal linkage zone corresponds to the Lung Meridian of Hand-Taiyin (upper arm) and the Stomach Meridian of Foot-Yangming (thigh), with an attenuation coefficient of 0.6-0.7. Moderate compensation is needed for muscle traction displacement near the trunk. The distal stable zone corresponds to the Large Intestine Meridian of Hand-Yangming (forearm) and the Gallbladder Meridian of Foot-Shaoyang (lower leg), with an attenuation coefficient of 0.3-0.4. Weak compensation is needed for low respiratory influence. The peripheral quiescent zone corresponds to the acupoints at the fingertips / toes, with an attenuation coefficient of 0.01.

[0094] For example, the calculation steps for the local compensation parameters are as follows:

[0095] Let the breathing compensation vector be... ,in, These are the horizontal and vertical displacement components of the respiratory compensation vector in the spatial coordinates of the body surface topological mapping, respectively.

[0096] S1. Determine the attenuation coefficient according to the meridian zone:

[0097] ;

[0098] S2. Dynamically adjust the attenuation coefficient based on the distance between the acupoint and the torso:

[0099] ;

[0100] In the formula, This is the adjusted attenuation coefficient. This represents the straight-line distance between the acupoint and the projection point of the xiphoid process. The adjustment factor is 0.5. It is the same as the body inch;

[0101] S3. Calculate the actual compensation vector, denoted as the local compensation parameter:

[0102] ;

[0103] In the formula, These are local compensation parameters;

[0104] Through the above technical solution, this application effectively reduces the interference of respiratory movement on the accuracy of acupoint positioning, enabling the surface topological mapping to accurately reflect the real anatomical structure under different respiratory phases. This compensation mechanism improves the coordinate stability in the dynamic acupuncture environment, avoids the risk of mis-needling caused by chest cavity fluctuations, and achieves precise compensation for different meridian areas through partition ratio conversion, ensuring the safety and effectiveness of treatment operations.

[0105] In an optional embodiment, the remote device further includes generating a treatment safety strategy based on an acupoint set, specifically including:

[0106] The confidence score is calculated based on the vector angle between each acupoint in the acupoint set and the interior angle of the convex polygon.

[0107] When the confidence score is lower than the lower limit of the preset confidence threshold interval, a forbidden acupuncture zone is marked at the corresponding acupoint coordinates.

[0108] When the confidence score is higher than the upper limit of the preset confidence threshold range, standard acupuncture parameters are invoked, including acupuncture duration and number of needles used.

[0109] When the confidence score is within the preset confidence threshold range, the acupuncture treatment duration is multiplied by the dynamic decay coefficient based on the confidence score to generate the actual acupuncture treatment duration;

[0110] For example, the dynamic attenuation coefficient is ,in, For each confidence score decrease of 0.1, the acupuncture treatment duration should be reduced by 15%.

[0111] It should be noted that anatomical studies have shown that the therapeutic effect decreases significantly when the acupoint positioning deviation is > ±7 mm. Furthermore, through statistical analysis of no less than 1500 treatment samples, the effective rate of acupoint treatment with a confidence level > 0.7 is > 92%. Therefore, the preset confidence threshold interval is set to [0.4, 0.7].

[0112] The forbidden acupuncture zone markers, actual acupuncture treatment duration, and standard acupuncture parameters are associated with acupoint coordinates to output a structured acupoint coordinate file containing a three-level safety strategy;

[0113] Compared with existing technologies, traditional systems only output fixed treatment plans based on preset rules and cannot dynamically adjust them according to the actual acupoint positioning quality. This solution establishes a quantitative evaluation mechanism through confidence scores and combines a three-level processing strategy to achieve flexible control of treatment parameters. At the same time, it integrates multi-dimensional safety information through structured files.

[0114] Through the above technical solution, this application can automatically divide the safe operation area according to the acupoint positioning accuracy, avoid applying press needles to acupoints with insufficient confidence, balance the efficacy and safety risks by dynamically adjusting the treatment time, and finally provide operation guidance containing multi-level safety strategies through structured data format.

[0115] In an optional embodiment, the formula for calculating the confidence score is:

[0116] ;

[0117] In the formula, The confidence score is... acupoints The angle between the vectors, The angle between the standard vectors. acupoints The convex polygon it is located in and Number them. The sum of the interior angles of a standard convex polygon;

[0118] For example, the included angle value of the standard vectors can be taken as follows: According to the anatomy of meridians and sinews, the average angle between vectors at the main acupoints is... The sum of the interior angles of a standard convex polygon is ;

[0119] Through the above technical solution, this application establishes a two-factor dynamic evaluation model, which can effectively identify complex positioning errors caused by local anatomical variations or overall morphological distortions. This can improve the fault tolerance and robustness of acupoint selection, accurately distinguish reliable acupoints from abnormal positioning points in scenarios with complex changes in body surface morphology, avoid treatment position deviations caused by misjudgment due to a single geometric feature, and provide quantitative decision-making basis for the generation of subsequent safety strategies.

[0120] In an optional embodiment, after the remote device calculates the confidence score, it also includes a body shape calibration mechanism:

[0121] Obtain the body mass index (BMI) and subcutaneous fat thickness measurements input by the user;

[0122] The body shape compensation coefficient is determined by comparing the body shape index value with the preset compensation coefficient reference table.

[0123] For example, Category I, with a body size compensation coefficient of 1.15; Category II, with a body size compensation coefficient of 1; Category III, with a body size compensation coefficient of 0.85;

[0124] Based on the subcutaneous fat thickness measurement, the local density influence factor is calculated;

[0125] The body size compensation coefficient is multiplied by the local density influence factor to generate a comprehensive calibration coefficient, which is then multiplied by the confidence score to generate a calibrated confidence score.

[0126] Compared with existing technologies, traditional press needle systems rely solely on static acupoint databases for coordinate matching, without considering the impact of user body shape differences and local tissue characteristics on acupoint positioning. This solution introduces a dual calibration mechanism of body shape index and subcutaneous fat thickness, which can dynamically adjust the confidence evaluation criteria. For example, when mapping body surface coordinates for obese users, the acupoint search range is expanded through a compensation coefficient, while the density factor is used to reduce the risk of misjudgment in areas with thicker fat, thus solving the positioning deviation problem caused by anatomical variations in traditional methods.

[0127] Through the above technical solution, this application realizes personalized calibration of confidence scores, which enables the acupoint selection process to fully adapt to the user's body shape characteristics and local tissue properties, improves the anatomical accuracy and treatment safety of the acupoint set, and ensures the reliability of the dynamic optimization process of acupuncture parameters.

[0128] In an optional embodiment, the formula for calculating the local density influence factor is:

[0129] ;

[0130] In the formula, As a local density influence factor, The fat-density attenuation coefficient. This is a measurement of subcutaneous fat thickness. This is the thickness compensation coefficient. Critical fat thickness; exemplarily, fat-density attenuation coefficient. Desirable The thickness compensation coefficient can be taken as 0.18, and the critical fat thickness can be taken as 20mm;

[0131] Through the above technical solution, this application solves the problem of misjudgment of acupoint location reliability caused by uneven distribution of subcutaneous fat. By dynamically adjusting the local density influence factor, the calibrated confidence score more accurately reflects the tissue characteristics of the target area, improves the adaptability of acupoint location for obese or thin patients, avoids mismarking of forbidden areas or inaccurate acupuncture parameter settings caused by excessively thick or thin fat layers, and enhances the effectiveness of treatment safety strategies.

[0132] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
