Description

Technical Field

[0001] The present invention relates to a method for controlling acupuncture, and in particular to a method for controlling light acupuncture. Background Art

[0002] Currently, in the field of intelligent acupuncture, such as Chinese patent CN118352025A, an intelligent acupuncture assistance system and method based on laser scanning and optical imaging are available. While existing optical acupuncture control methods have made some progress in the digitalization and intelligentization of traditional acupuncture, the overall technical system still has significant shortcomings and limitations, mainly reflected in the following aspects: First, the core advantage of existing technologies lies in the three-dimensional spatial positioning of human acupoints through laser scanning and point cloud imaging technology. PCN point cloud completion and PointNet semantic segmentation improve the accuracy of acupoint positioning, solving the problems of large errors and strong dependence on the doctor's visual positioning. However, this solution belongs to the category of static spatial positioning, mainly based on fixed modeling of the three-dimensional structure of the human surface, and lacks real-time perception and feedback regulation of the human body's dynamic physiological state. In clinical applications, patients often experience real-time fluctuations in heart rate, respiration, and electromyographic activity during acupuncture treatment. Changes in body surface microcirculation and tissue temperature gradients can cause micro-displacement of acupoints. Existing systems do not address the collection and closed-loop control of these dynamic physiological data. As a result, although spatial positioning is accurate, functional state regulation is lacking, and dynamic response to the patient's neurophysiological changes cannot be achieved, affecting the sustained effectiveness of the stimulation effect.

[0003] Secondly, existing optical acupuncture systems use simple directional laser irradiation output and lack multi-dimensional light field control capabilities, such as spatial energy distribution control and dynamic management of interference fringes. This makes it impossible to achieve the function of non-target acupoint inhibition during multi-acupoint optical stimulation. This system uses laser irradiation for acupoint marking and auxiliary positioning, but in actual treatment, it does not solve the problem of energy crosstalk when irradiating multiple acupoints in parallel, and cannot establish a selective inhibition window through spatial phase control. This may lead to false stimulation or side effects in some sensitive patients. In particular, in treatments involving autonomic rhythm regulation, excessive stimulation may cause arrhythmias or blood pressure fluctuations. In addition, this patent mainly uses expert experience and database solutions for diagnosis and treatment recommendations. Although it has the function of machine learning to optimize diagnosis and treatment plans, it lacks comprehensive perception and interaction with patients' real-time physiological rhythms, does not introduce the concept of rhythm coupling, and uses a fixed optical stimulation output scheme. It does not consider the problem of coordinated resonance of neural rhythms such as heart rate, respiration, and pulse. This leads to rhythm disconnection during treatment, and the stimulation timing cannot match the natural fluctuations of the patient's nervous system, which reduces the efficiency of neuroplasticity stimulation. Thirdly, the existing technology lacks a rhythm differential resynchronization control mechanism and does not adopt a phase shifting strategy to break the fixed response pattern of the nervous system. Long-term use can easily lead to adaptive fatigue of the nervous system or ineffective stimulation. In particular, in the application of light acupuncture for chronic diseases such as insomnia, anxiety, and autonomic nervous system disorders, a single rhythmic stimulation mode can easily lead to diminishing efficacy. The patent also does not use a random perturbation mechanism to regulate micro-variations in the stimulation time window, and cannot effectively avoid neural fixation reactions. In addition, the existing system does not perform phase compensation for tissue optical properties (such as scattering and refractive index differences) during laser output, and does not consider the path changes of the laser during subcutaneous propagation, which interferes with the consistency between the actual energy distribution and the preset model and affects the accuracy of the treatment target. In terms of energy management, the patent does not design a dynamic regulation of the polarization state of light, and cannot reduce the residual light absorption in the interference quiet zone through orthogonal polarization interference. There is a potential risk of tissue microheat accumulation and nonlinear photobiological effects.

[0004] Finally, existing technologies do not incorporate real-time evaluation and feedback of the autonomic nervous system, lack excitability regulation functions based on indicators such as HRV, galvanic skin response, and microcirculation, and cannot automatically adjust the stimulation frequency or intensity according to the patient's sympathetic and parasympathetic fluctuations during treatment. This can easily lead to problems of over-excitation or inhibition of the nervous system during treatment, affecting treatment safety and individualized adaptability. Summary of the Invention

[0005] The purpose of the present invention is to provide a control method for light acupuncture, thereby solving some of the drawbacks and deficiencies pointed out in the background art.

[0006] The present invention solves the above-mentioned technical problems by adopting the following technical solution: a control method for optical acupuncture, comprising: a control system continuously applying multiple light stimulation pulses below the nerve excitation threshold, so as to cause the target acupoint nerve to enter a subcritical energy storage state through the superposition of postsynaptic membrane potential; when a slight jump in the electrical response of the target acupoint is detected, the control system increases the laser output intensity and emits a directional threshold-crossing pulse to trigger nerve discharge; During the subcritical stimulation process, the control system determines the main axis direction of local tissue fibers by detecting the time difference of the subcutaneous tissue micro-oscillation response, and adjusts the laser incident angle in the subsequent threshold-crossing pulse to allow the light beam to penetrate along the main axis direction to induce compliant tissue resonance. The control system uses two frequency-difference laser beams to cross-irradiate the non-treatment acupoint area to be inhibited to form fixed interference fringes, and calculates the minimum power landing point in the interference fringes to cover the target acupoint for inhibition, so that the acupoint is always in the interference cancellation band during the treatment process to form a selective functional inhibition window. At the initial stage of illumination, the second-order derivative of the thermal expansion rate of the temperature curve in the target acupuncture point area is calculated in real time. When the thermal expansion rate changes from increasing to decreasing, it is identified as the midpoint of thermal diffusion, and the laser output is interrupted to allow the tissue to complete deep energy conduction on its own during the diffusion-dominant period. The control system synchronously collects the user's heart rate and respiratory signals, extracts their respective cycles and calculates the minimum common beat, and sets the subsequent light stimulation rhythm to the physiological rhythm differential resynchronization frequency, so as to achieve alternating resonance activation of different neural rhythms through phase shifting.

[0007] Furthermore, the method for calculating the minimum power landing point in the interference fringes to cover and inhibit the target acupuncture point includes: A control system applies two phase-controllable or frequency-slightly different laser beams for cross-irradiation, forming a set of spatially distributed interference fringes. The interference fringes include a light intensity superposition region and a light wave phase cancellation region. The light intensity superposition region is an energy enhancement region, and the light wave phase cancellation region is an interference quiet region. The control system calculates the spatial distribution of the interference fringes based on the incident angle, wavelength difference, and phase difference of the two laser beams, and determines the light intensity distribution position of each interference zone. For the target acupuncture point to be suppressed, the control system determines whether the target acupuncture point is located within the interference quiet zone based on the spatial coordinates of the target acupuncture point. If the target acupuncture point is not within the interference quiet zone, the control system moves the interference fringes in real time by adjusting the relative phase or incident angle of the two laser beams so that the minimum power landing point within the interference quiet zone is aligned with the center position of the target acupuncture point, and the minimum power landing point is the light intensity extreme point within the interference quiet zone; By keeping the target acupuncture point at the minimum power landing point in the interference quiet zone, the selective function of the target acupuncture point during the light acupuncture treatment is suppressed, so that the target acupuncture point is always in the effective light power offset area during laser irradiation.

[0008] Furthermore, the control system dynamically adjusts the phase offset of the interference fringes based on the physiological state data of the target acupuncture points during the formation of the interference quiet zone. The physiological state data includes changes in skin resistance, microcirculatory blood flow or temperature gradient in the acupoint area. By real-time monitoring of the physiological state, when it is detected that the spatial coordinates of the target acupoint are offset due to physiological changes in the tissue, the position of the interference quiet zone is corrected so that the inhibition window always covers the effective stimulation area boundary of the target acupoint.

[0009] Furthermore, the control system integrates the optical scattering characteristics of subcutaneous tissue and the difference in tissue refractive index in the calculation of the spatial distribution of interference fringes, and dynamically adjusts the positioning accuracy of the interference quiet zone by correcting the phase drift generated by the light propagation path and the tissue interface to improve the matching degree of the inhibition window for the target acupuncture points in the human tissue structure.

[0010] Furthermore, the control system adjusts the polarization state difference between the two laser beams in the power control of the interference quiet zone so that the remaining light field in the interference quiet zone is orthogonal polarized light that is perpendicular to each other, thereby reducing tissue absorption efficiency and suppressing potential nonlinear photobiological effects; after completing the interference suppression control of the target acupuncture points, the control system periodically switches the position of the interference fringes and rotates the interference quiet zone among multiple non-treatment acupuncture points at a preset rhythm, thereby achieving sequential optical suppression of different non-target acupuncture points.

[0011] Furthermore, the method of extracting respective periods and calculating the minimum common beat includes: A control system collects multiple physiological rhythm signals in real time, wherein the physiological rhythm signals include heart rate signals, respiratory rate signals, pulse wave signals or myoelectric rhythm signals; extracts the periods of each type of physiological rhythm signal, identifies and calculates the basic period of each type, converts the basic period into a time interval, and establishes a rhythm time reference; Based on the rhythmic time reference, the control system calculates the minimum common beat among the multiple physiological rhythms. The minimum common beat is the time node where the natural cycles of the rhythms meet on the time axis, representing the moment when the multiple rhythms are relatively consistent or interact with each other; the stimulation rhythm benchmark of the light acupuncture is set to the minimum common beat, so that the light stimulation output can be carried out within the common acceptance time window of the multiple nervous system rhythms; The specific operation includes the following steps: 1. Circadian Rhythm Collection and Cycle Extraction A control system collects multiple physiological rhythm signals in real time, wherein the physiological rhythm signals include heart rate signals, respiratory rate signals, pulse wave signals or myoelectric rhythm signals; extracts the period of each physiological rhythm signal, identifies the respective basic period, converts the period into a time interval, and establishes a rhythm time reference; 2. Minimum common beat calculation and differential resynchronization control Based on the rhythm time reference, the following innovative rhythm superposition function is proposed: in: is the multi-rhythm synergy function, which represents the rhythm resonance intensity at time t; is the number of physiological rhythms, such as heart rate, respiration, pulse, and myoelectricity, n ≥ 2; For the The basic cycle of the physiological rhythm; For the The phase offset of each rhythm is used for rhythm differential resynchronization; To control the time weight factor of memory decay, is the attenuation coefficient; It is the periodic cumulative effect of all rhythmic signals, indicating the cross-action of physiological rhythms; To achieve cumulative synergy through integration and ensure the historical superposition effect of rhythmic resonance; when When the value of is close to the local maximum within its cycle, it means that multiple rhythms have reached a coordinated resonance in timing; the control system uses this as a judgment basis to align the output pulse rhythm of the light acupuncture with the The local maximum value of the phase offset can achieve synchronous stimulation output of multiple rhythms; Can be adjusted in real time to form rhythm differential resynchronization control to prevent a single rhythm from dominating; attenuation factor The introduction of time memory allows the system to prioritize responses to recent rhythmic changes and avoid excessive lag.

[0012] Furthermore, the control system adopts a rhythm differential resynchronization control strategy, introduces phase shift during the stimulation process, and actively deviates the output rhythm of light stimulation moderately from the phase peak or valley of different rhythms in each cycle, forming an alternating stimulation and recovery pattern.

[0013] Furthermore, the control system performs weighted processing on the instantaneous fluctuation trends of various physiological rhythm signals when calculating the minimum common beat, wherein the weighting factor is dynamically adjusted according to the needs of the current treatment stage, so that the influence weight of the priority-associated rhythm on the minimum common beat in the treatment scenario is increased; when implementing the phase shift, the rhythm differential resynchronization control strategy dynamically adjusts the direction and amplitude of the phase offset according to the differential change trend between each rhythm, so that the phase shift can be used to enhance the stimulation effect and prevent excessive synchronization of specific rhythms.

[0014] Furthermore, the control system superimposes a slight random perturbation signal during the rhythm differential resynchronization process, and by introducing the randomness of the perturbation, breaks the fixed response of the nerves and makes the stimulation rhythm variable.

[0015] Furthermore, the control system combines the real-time evaluation of the human body's autonomic nervous system state each time the minimum common beat occurs. If the autonomic nervous system is monitored to have an excitatory or inhibitory trend, the subsequent light stimulation beat rhythm is adjusted. By shortening or lengthening the time interval between adjacent stimulations, the real-time balance of the autonomic nervous system excitability is regulated.

[0016] The present invention has the following beneficial effects: By collecting multiple physiological rhythms, such as heart rate, respiration, pulse waves, and electromyography in real time, calculating the minimum common beat, and combining phase differential control, it achieves multi-rhythm synergistic resonance stimulation. Compared to traditional single-frequency light acupuncture, the present invention can dynamically adjust the timing of light stimulation output according to the patient's actual physiological state, dynamically adapting the stimulation rhythm to the human physiological rhythm, significantly improving the efficiency and efficacy of the nervous system's excitation response. Through the spatial control method of the interference quiet zone, two laser beams are intersected to form adjustable interference fringes, and the minimum power landing point is used to achieve selective inhibition of non-target acupoints. By dynamically adjusting the phase and angle, the optical power extremes are precisely aligned with the acupoints to be inhibited, avoiding the energy crosstalk problem of traditional light acupuncture in multi-acupoint treatment and reducing the risk of misstimulation, neural chain interference, or side effects. Based on tissue physiological data such as skin resistance, microcirculation, and temperature gradients, the spatial coordinates of the acupoints and the position of the interference quiet zone are corrected in real time, automatically compensating for coordinate offsets caused by changes in patient position, tissue thermal expansion and contraction, or local blood flow fluctuations, achieving closed-loop dynamic control of the illumination area and ensuring consistent stimulation accuracy.

[0017] By combining rhythmic phase shifting with random perturbations, the system proactively avoids prolonged, fixed synchronization of the light stimulation rhythm with a single rhythm, creating an output pattern of alternating stimulation and recovery. This effectively prevents adaptive blunting of the nervous system to repeated stimulation, maintains neural network sensitivity, and enhances the sustainability and effectiveness of long-term treatment. At each stimulation point, the system automatically assesses autonomic nervous system status in real time. If sympathetic or parasympathetic hyperactivity is detected, the frequency and intensity of subsequent light stimulations are automatically adjusted. By shortening or lengthening the stimulation interval, the system achieves balanced regulation of autonomic nervous system function, supporting adaptive treatment and is particularly suitable for conditions requiring autonomic intervention, such as heart rate variability, insomnia, anxiety, and cardiovascular regulation. Orthogonal polarization control ensures that residual light energy within the interference quiet zone reaches tissues in a state of minimal absorption, reducing the likelihood of nonlinear photobiological effects, avoiding microthermia accumulation and tissue damage, and ensuring the safety of light acupuncture treatment, making it particularly suitable for long-term, continuous use. Dynamic rotation of the interference quiet zone allows for alternating inhibition between multiple non-treatment acupoints, preventing local tissue tolerance caused by long-term, fixed inhibition. This improves the controllability of multi-acupoint coordinated treatment and expands the operational range and intelligence of the light acupuncture system. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0024] Combined with attachment Figure 1, the present invention provides a control method for light acupuncture, which adopts continuous low-threshold light stimulation pulses, combined with subcritical energy storage and directional threshold-crossing control, to achieve precise excitation and individualized regulation of acupuncture point nerves. First, the control system continuously performs light stimulation on the target acupuncture point to be treated, and the power of the applied light stimulation pulse is controlled at a level lower than the nerve excitation threshold, so that a single pulse will not directly trigger the nerve action potential, thereby avoiding direct discharge and sudden excitation of the nerve. Each light stimulation pulse will produce a weak bioelectric response in the skin and nerve tissue of the target acupuncture point. This weak reaction forms a gradual superposition of potentials on the postsynaptic membrane of the nerve. Due to the continuous application of multiple pulses, the postsynaptic membrane potential will gradually accumulate, so that the nervous system is in a subcritical energy storage state, that is, it has not yet reached the action potential triggering threshold but is gradually approaching it. This subcritical state is sensed by the control system's built-in real-time monitoring module, which monitors the local electrical response signals at the target acupoints via electrophysiological sensors on the skin surface or near the acupoint area. When a slight jump in the electrical response at the target acupoint is detected, particularly when the postsynaptic membrane potential reaches a certain warning level but has not yet spontaneously discharged, the control system immediately identifies this as a critical state, impending the threshold for neural excitation. At this point, the control system determines the optimal timing for controlled neural excitation based on a preset algorithm, increases the laser output intensity, and emits a targeted transthreshold pulse. This targeted transthreshold pulse is a short burst of high-power light output. The power and pulse duration are carefully controlled to ensure that it precisely exceeds the triggering threshold of the nerve action potential, triggering effective discharge at the target acupoint. This discharge process does not rely on external forced electrical stimulation. Instead, it uses gradually superimposed subthreshold light stimulation to induce the nervous system to spontaneously enter an excitable state, ultimately completing targeted transthreshold excitation with minimal energy stimulation. This effectively reduces energy input and the risk of tissue damage, while better simulating the physiological phenomenon of "qi" (de qi) during traditional acupuncture.

[0025] By interfering the tissue response characteristics during subcritical stimulation with spatial energy distribution, precise activation of target acupoints and selective inhibition of non-target areas are achieved, enhancing the safety and effectiveness of light acupuncture treatment. During light acupuncture treatment, the control system first applies continuous subcritical light stimulation pulses. Specifically, the target acupoint is illuminated multiple times for short periods of time at a light power below the nerve excitation threshold. This process not only allows for subcritical energy storage in the nerve, but also utilizes this stimulation phase to collect real-time micro-oscillation response signals from the subcutaneous tissue in the area where the target acupoint is located. The micro-oscillation response is captured by a highly sensitive tissue vibration detection module. The control system performs time difference analysis on these vibration signals, comparing the tissue oscillation conduction delays in different directions to determine the main axis orientation of the local tissue fibers. Because muscle fibers, fascia, and connective tissues in human tissue are anisotropic, their mechanical conduction velocities vary measurably in different directions. Based on this physical property, the control system calculates the direction of minimum delay as the main axis of the tissue, enabling dynamic identification of the tissue main axis. Subsequently, when directional threshold-crossing pulse output is performed, the control system adjusts the incident angle of the laser emitting device according to the acquired principal axis direction, so that the laser beam penetrates along the principal axis of the tissue fibers. This reduces light scattering losses in non-principal axis directions, enhances the efficiency of light energy transmission deep within the tissue, and simultaneously induces a compliant tissue resonance effect. This compliant tissue resonance can further stimulate the tissue's mechanical receptors and enhance the overall physiological effect of light acupuncture stimulation. In addition, to prevent secondary stimulation or cross-interference in non-treatment areas, the control system uses two laser beams with slightly different frequencies to cross-irradiate the non-treatment acupoint area to be suppressed. Using the principle of interference, fixed interference fringes are formed within the target area. The interference fringes include a region of superimposed light intensity and a region of light wave phase cancellation. The phase cancellation region is the interference quiet zone, which is a low-power or zero-power region. The control system calculates the spatial distribution of the interference fringes based on the incident parameters of the two laser beams, further analyzes the position of the interference quiet zone, and precisely adjusts the relative phase and incident angle of the lasers so that the minimum power point in the interference quiet zone precisely covers the center of the non-treatment acupoint to be suppressed, forming a selective functional inhibition window.

[0026] By real-time synchronous control of the temperature dynamics of local tissues and multiple physiological rhythms, efficient conduction of light stimulation and coordinated activation of the nervous system are achieved. During the light acupuncture treatment process, the control system first monitors the temperature changes of the target acupuncture point area in real time at the beginning of the illumination, and continuously collects the temperature curve data of the local target acupuncture point through the temperature-sensitive sensor device. The control system dynamically analyzes the temperature curve, especially calculates the first-order derivative of the temperature change, that is, the thermal expansion rate, and the second-order derivative, that is, the trend of the change of the thermal expansion rate. When it is detected that the second-order derivative of the thermal expansion rate changes from positive to negative, that is, from an increasing trend to a decreasing trend, it is judged as the midpoint of the thermal diffusion of the local tissue. This midpoint represents the transition of the local tissue from the main heat accumulation stage to the heat diffusion-dominated stage. At this time, continuing to apply the laser will cause local overheating or invalid energy accumulation. Therefore, the control system immediately interrupts the laser output after identifying the midpoint of thermal diffusion and enters the energy diffusion period. In the absence of continued illumination, the tissue relies on its own thermal diffusion effect to conduct energy from the superficial layer to the deep tissue, completing the indirect energy replenishment of the deep acupuncture point area, avoiding thermal damage while increasing light energy. tissue conduction efficiency; at the same time, the control system also synchronously collects the user's heart rate signal and respiratory signal, obtains the heartbeat cycle and respiratory cycle in real time through a multi-channel physiological monitoring device, and extracts their respective basic cycles to form a periodic time series; the control system calculates the minimum common beat of heart rate and respiration based on the time series. The minimum common beat is the common node where the two rhythms meet on the time axis, which is used as the basic timing of multi-system rhythm coupling; then, the control system sets the subsequent stimulation rhythm benchmark of light acupuncture to the minimum common beat to ensure that the stimulation output falls within the time window of multi-rhythm overlap, and further adopts a rhythm differential resynchronization control strategy, that is, by introducing a moderate offset to the rhythmic phase of heart rate and respiration, setting the phase stagger of light stimulation output, so that light stimulation forms an alternating resonant activation mode between multiple physiological rhythms, which can not only stimulate the excitatory response of the autonomic nervous system, but also avoid the adaptive desensitization caused by long-term synchronization of a single rhythm.

[0027] Combined with attachment Figure 2Through dynamic control of spatial interference fringes, selective functional inhibition of non-therapeutic acupoints is achieved, preventing non-target acupoints from being accidentally stimulated due to energy diffusion or beam coverage errors during multi-acupoint light acupuncture treatment. The control system applies two phase-controllable or frequency-slightly different laser beams for cross-irradiation, using the principle of interference to form a set of spatially distributed interference fringes in the tissue space. The interference fringes are formed by the intersection of the wavefronts of the crossed lasers, forming a spatial light intensity variation zone. The interference fringes include a light intensity superposition zone and a light wave phase cancellation zone. The light intensity superposition zone is an energy enhancement zone formed when the two laser waves are in phase, where the light power reaches a local peak and is suitable for therapeutic stimulation. The light wave phase cancellation zone is an interference quiet zone formed when the two laser waves are in phase opposition, where the light intensity is reduced to a minimum or close to zero, forming an energy shielding zone. Based on the incident angle, wavelength difference, and phase difference of the two laser beams, combined with the spatial geometric relationship of the laser light path, the control system calculates the spatial distribution of the interference fringes, determines the light intensity distribution position of each interference zone, and constructs a spatial power map of the interference fringes. For the target acupoint to be inhibited, the control system obtains the spatial coordinates of the target acupoint and determines whether it is located within the interference quiet zone. This determination is based on the matching relationship between the spatial positioning module and the laser fringe pattern. If the target acupoint is not within the interference quiet zone, the control system activates a dynamic adjustment mechanism. Using a laser phase controller or optical deflection device, the control system adjusts the relative phase or incident angle of the two laser beams to move the position of the interference fringe in real time, ensuring that the minimum power landing point within the interference quiet zone is aligned with the center of the target acupoint. The minimum power landing point refers to the local extreme point of optical power within the interference quiet zone, where the light intensity is close to zero, forming a spatial energy shielding node in a physical sense. By keeping the target acupoint at the minimum power landing point in the interference quiet zone, the target acupoint can always be in the effective optical power cancellation area during the light acupuncture treatment process, achieving selective functional inhibition of the target acupoint. This prevents non-treatment acupoints from receiving sufficient light energy during laser irradiation, avoiding nerve excitation or tissue reaction, ensuring the stimulation efficacy of the primary treatment acupoint is not affected, and simultaneously blocking the risk of inadvertent stimulation of secondary treatment acupoints or potentially sensitive areas.

[0028] Dynamic control of the interference quiet zone is achieved through real-time physiological state feedback, making the suppression of non-target acupoints during light stimulation more precise and stable. During light acupuncture treatment, the control system, building on the formation of the interference quiet zone, further dynamically adjusts the phase offset of the interference fringes based on the physiological state data of the target acupoint, achieving real-time correction and continuous coverage of the suppression window. Specifically, the control system first applies two phase-controlled or frequency-differential laser beams to cross-irradiate the target tissue region, forming interference fringes. The interference fringes consist of a region of superimposed light intensity and a region of light wave phase cancellation. The light wave phase cancellation region, known as the interference quiet zone, is a spatial region with extremely low or near-zero light power, which is used for optical suppression of non-target acupoints. Through spatial positioning and calculation, the control system initially aligns the minimum power point in the interference quiet zone with the center of the target acupoint. However, considering that human tissue is not completely static during light stimulation, local physiological conditions can cause subtle spatial coordinate changes, leading to displacement of the acupoint position. For example, tissue expansion caused by changes in blood flow, shifting of the electrophysiological response zone due to changes in skin resistance, or thermal expansion and contraction of the tissue due to temperature gradients. To this end, the control system continuously collects physiological status data of the target acupuncture points in real time. The physiological status data includes but is not limited to changes in skin resistance in the acupuncture point area, microcirculatory blood flow, and temperature gradients on the surface or deep layer of the tissue. The data is collected at a high frequency through a physiological sensor array and uploaded to the central processing unit. The control system dynamically analyzes the physiological status data and uses a correlation model between tissue status and spatial coordinate changes to determine whether the actual position of the target acupuncture point during the illumination process is consistent with the current positioning of the interference quiet zone. When it is detected that the spatial coordinates of the target acupuncture point are offset due to physiological changes in the tissue, the control system immediately activates the interference fringe phase adjustment mechanism, fine-tunes the spatial distribution of the interference fringes by adjusting the relative phase of the two laser beams, and dynamically corrects the position of the interference quiet zone so that the minimum power landing point in the interference quiet zone is always aligned with the current center coordinate of the target acupuncture point, ensuring that the inhibition window continuously covers the effective stimulation area boundary of the target acupuncture point.

[0029] In order to solve the problem of the influence of the complex tissue structure of the human body on the light propagation path, a dynamic interference fringe control strategy combining the optical characteristics of the tissue is proposed. During the light acupuncture treatment process, the control system forms spatial interference fringes by applying two phase-controllable or frequency-slightly different laser beams for cross-irradiation. The interference fringes are used to establish an energy distribution in the target area, including a light intensity superposition area and a light wave phase cancellation area. The light wave phase cancellation area is the interference quiet zone, which has the characteristic of extremely low light power and is used to achieve optical suppression of non-treatment acupuncture points. However, human skin and its underlying tissues have non-uniform optical properties, especially the differences in optical scattering characteristics and refractive index between different tissue layers. These factors will cause the laser propagation path in the tissue to bend, scatter, attenuate and phase delay, which directly affects the actual distribution position of the interference fringes in the body, resulting in deviations in the spatial alignment between the interference quiet zone and the target acupuncture point. To this end, the control system comprehensively considers the optical scattering coefficient of the skin and subcutaneous tissue, the refractive index differences at each tissue interface, and the anisotropic light propagation characteristics when calculating the spatial distribution of interference fringes. By establishing a propagation path correction model based on the optical parameters of the tissue layer, the actual propagation trajectories of the two laser beams are dynamically calculated, predicting the phase drift and path deflection caused by the tissue interface. Phase drift includes phase delay caused by changes in the tissue optical path and random phase perturbations caused by scattering. Based on the model, the control system makes real-time corrections to the laser's incident angle, phase control, and spatial predictions of the interference fringes, aligning the theoretical position of the interference quiet zone with the actual interference effect within the tissue. The control system further dynamically adjusts the relative phase, polarization state, or incident path of the two laser beams to achieve precise positioning of the interference quiet zone within the tissue.

[0030] By combining spatial optical interference with polarization state control, the light absorption effect of non-target acupoints is further reduced, and dynamic suppression of multiple acupoint areas is achieved. During the light acupuncture treatment process, the control system applies two laser beams to cross-irradiate to form spatial interference fringes. The interference fringes include a region of superimposed light intensity and a region of light wave phase cancellation. The light wave phase cancellation region is the interference quiet zone, a spatial region with extremely low light intensity, which is used to optically suppress non-treatment acupoints. In actual tissue environments, although the interference quiet zone can reduce the total light intensity, there is still a very small residual light field. Especially in scattering media or microstructured tissues, the residual energy will be locally absorbed, triggering nonlinear photobiological effects, such as weak heat accumulation, tissue microexcitation or photoinduced effects. In order to avoid such potential adverse reactions, the control system further dynamically adjusts the polarization state of the two laser beams during the power control process of the interference quiet zone, so that the two laser beams form mutually perpendicular orthogonal polarized light fields in the interference quiet zone. The mutual interference ability of orthogonally polarized light beams in the tissue is zero, the energy will not be superimposed, and they will not affect each other, so that the residual light field in the interference quiet zone is in an extremely low energy state, which reduces the tissue's absorption efficiency of the residual light, greatly reduces the probability of nonlinear photobiological effects, and achieves better treatment of non-target acupuncture points. Thorough optical inhibition; after completing the interference inhibition of a single target acupoint, the control system further executes a sequential inhibition strategy, periodically switches the position of the interference fringes, and adjusts the phase or incident angle of the two laser beams to make the interference quiet zone rotate between multiple non-treatment acupoint areas according to a preset rhythm, covering different non-target acupoints in turn, and realizing serialized optical inhibition control. The rotation mechanism can avoid the local tissue adaptive response caused by long-term fixed inhibition of a single acupoint, maintain the equilibrium state of the overall neural network, ensure that the main acupoint continues to receive light stimulation during the treatment process, and the non-target acupoints are in an effective light power offset state in turn, preventing energy mis-irradiation or excessive tissue activation, and realizing dynamic and time-sharing inhibition of multiple acupoint areas, further improving the safety, accuracy and individual adaptability of light acupuncture treatment.

[0031] Combined with attachment Figure 3 , adopting the collaborative calculation and differential resynchronization strategy of multiple physiological rhythms to achieve individualized light stimulation output timing control and enhance the coordinated response ability of the nervous system. During the treatment process, the control system collects the user's multiple physiological rhythm signals in real time through the multi-channel physiological monitoring module. The physiological rhythm signals include heart rate signals, respiratory rate signals, pulse wave signals and electromyographic rhythm signals. The control system extracts the period of each physiological rhythm signal separately, identifies and calculates the basic period of each rhythm, converts the basic period into a time interval, forms a rhythm time reference, and establishes a real-time updated rhythm period database. Based on the rhythm time reference, the control system further calculates the minimum common beat between multiple physiological rhythms, proposes a multi-rhythm collaborative superposition function, and uses the following formula for comprehensive calculation: in, is a multi-rhythm coordination function, which means that The rhythmic resonance intensity at The number of physiological rhythms, such as heart rate, respiration, pulse, and myoelectricity, meets ; For the The basic cycle of the physiological rhythm, in seconds; For the The phase offset of each rhythm is used for rhythm differential resynchronization regulation; It is the periodic cumulative effect of all rhythmic signals, indicating the cross-action of different physiological rhythms; is the attenuation coefficient, which controls the memory weight of historical rhythm data. Its unit is the inverse of time. The larger it is, the more the system focuses on recent data; is the time weight factor, which represents the attenuation effect of historical data; The integration of historical data ensures the historical superposition effect of rhythmic resonance. When the value of is close to the local maximum within its cycle, it means that multiple physiological rhythms have reached synergistic resonance on the time axis. The control system uses this as a basis for judgment and aligns the output pulse rhythm of light acupuncture with The local maximum of the phase offset is adjusted to achieve the synchronous stimulation output of multiple rhythms. , can differentially resynchronize each rhythm, avoid a single rhythm dominating the light stimulation sequence, form a rhythm alternating stimulation strategy, and effectively prevent the nervous system from producing adaptive fatigue or monotonous response. The introduction of makes the system have time memory, which can give priority to responding to recent rhythm changes, dynamically adapt to the patient's current physiological state, avoid timing lag caused by long-term accumulation, and ensure that the light acupuncture stimulation output is carried out within the common acceptance window of multi-system rhythms, thereby achieving alternating resonant activation and improving the response sensitivity and therapeutic effect of the overall nervous system.

[0032] A rhythm differential resynchronization control strategy is adopted to achieve a multi-rhythm coordinated alternating stimulation and recovery mode by introducing phase shifting during the light stimulation output process. During the light acupuncture treatment process, the control system first collects a variety of physiological rhythm signals in real time, including heart rate, respiratory rate, pulse waveform and electromyographic rhythm, etc., extracts the basic period and phase information of each physiological rhythm through the signal processing module, and establishes a rhythm reference model. The traditional synchronous stimulation mode usually strictly aligns the light stimulation output with the phase peak or valley of a certain physiological rhythm, but the present invention does not adopt a complete synchronization strategy, but actively introduces phase shifting between each physiological rhythm through rhythm differential resynchronization control, and designs the light stimulation rhythm to maintain a moderate deviation from the phase peak or valley of different rhythms. Specifically, the control system calculates the phase difference value according to the period and phase of each rhythm, and dynamically adjusts the output time of the light pulse in each stimulation cycle, so that some stimulation pulses fall near the rising edge of the heart rate cycle, and some stimulation pulses fall in the respiratory cycle. Near the falling edge of the EMG rhythm, some pulses are offset to the middle section or other non-extreme areas of the EMG rhythm. Through this phase dispersion strategy, the light stimulation output forms an alternating stimulation and recovery rhythm on the time axis, avoiding the neural adaptation caused by the continuous locking of a single rhythm. The alternating mode can not only stimulate the comprehensive response of the autonomic nervous system and the peripheral nervous system, but also guide part of the time period during the stimulation into the neural recovery period, reducing the risk of neural fatigue. In addition, the amplitude of the phase shift is adjusted in real time by the control system. Combined with the individual's real-time physiological state, such as heart rate variability, respiratory amplitude or changes in EMG activity, the output rhythm of the light stimulation is dynamically optimized to achieve a precise match between the stimulation intensity and the recovery timing, thereby forming a treatment mode of alternating continuous stimulation and intermittent recovery, achieving continuous stimulation of the excitability of the nervous system while ensuring the dynamic balance of the physiological rhythm.

[0033] Individualized rhythm-driven light stimulation output is achieved through dynamic weight control and differential phase resynchronization strategy of multiple physiological rhythms. During the light acupuncture treatment, the control system collects multiple physiological rhythm signals in real time. The physiological rhythm signals include heart rate signals, respiratory rate signals, pulse wave signals and electromyographic rhythm signals. Through the signal acquisition module and period extraction algorithm, the basic period and instantaneous phase of each rhythm are calculated respectively. At the same time, the short-term fluctuation trend of each rhythm, that is, the dynamic change rate and amplitude change of the rhythm, is monitored. When calculating the minimum common beat of multiple rhythms, the control system does not use a simple equal-weighted period superposition, but weights the instantaneous fluctuation trends of various physiological rhythms, introduces a weight adjustment factor, and dynamically adjusts the influence of each rhythm according to the treatment stage. The weighting factor can be set according to the treatment goal. For example, in sedation treatment, the weight of the respiratory rhythm is relatively increased. When stimulating the sympathetic nerves, the weight of the heart rate rhythm is prioritized. The control system dynamically assigns the weighting factor according to the real-time monitoring data to form a minimum common beat with stage adaptability, so that the priority-associated rhythm has an impact on the common beat. The degree of influence is improved to ensure that the light stimulation output is more in line with the physiological needs of the current treatment scenario; in the rhythm differential resynchronization control process, the control system implements a phase shift strategy according to the above-mentioned weighted rhythm characteristics. The phase shift is not a fixed offset, but dynamically adjusts the direction and amplitude of the phase offset according to the differential change trend between each rhythm. Specifically, when a rhythm is detected to be accelerated or slowed down for a short time, the system appropriately changes the output time point of the light stimulation pulse according to the differential change trend, so that the rhythm of the light stimulation presents a dynamic slip relative to the phase of the rhythm, which can enhance the stimulation effect of the light stimulation during the rhythm enhancement period by forming a synergistic amplification with the rhythm peak offset, and can also avoid the synchronization area by adjusting the phase offset when the rhythm is over-synchronized or resonates at high frequency, thereby reducing the load of continuous superposition on the specific nervous system and achieving dynamic enhancement or protective inhibition of the stimulation effect, thereby achieving the goal of enhancing the neural stimulation effect, reducing the risk of side effects and maintaining the diversity of rhythmic stimulation.

[0034] By superimposing a slight random perturbation signal during the rhythm differential resynchronization process, the adaptability of the nervous system to a single fixed rhythm is broken, thereby maintaining the dynamic variability of the stimulation rhythm. During the light acupuncture treatment process, the control system first collects a variety of physiological rhythm signals from the user, including heart rate, respiratory rate, pulse wave and electromyographic rhythm, etc., identifies the basic period and phase of each rhythm through the cycle extraction algorithm, establishes a rhythm reference timing, and calculates the minimum common beat of multiple rhythms according to treatment needs to form a basic stimulation rhythm; in order to avoid long-term single rhythm stimulation causing the nervous system to produce a fixed reaction or adaptive desensitization, on the basis of rhythm differential resynchronization, a slight random perturbation signal is further superimposed on the output timing of the light stimulation. The perturbation signal is generated by the random noise generation unit of the control system, and the perturbation amplitude is set within the physiological acceptance range. The perturbation frequency interacts with the rhythm to ensure that the basic synchronization framework of the overall rhythm is not destroyed, but it is sufficient to introduce subtle uncertainty in each output cycle, so that the output time of the stimulation pulse produces a small random offset in phase. The offset can It can be an advance or delay of the output time, or a slight change in the pulse width; this perturbation mechanism is superimposed on the rhythm differential resynchronization output rhythm in real time through the control system, so that the timing of each light stimulation has controllable random fluctuations, breaking the monotony of traditional fixed-phase stimulation, and preventing the nervous system from entering an adaptive state or forming stimulation fatigue due to excessive repetition. Especially in long-term treatment, the introduction of random perturbations can maintain the response activity of the neural network, maintain neural plasticity, and prompt the nervous system to continue to produce sensitive responses to stimulation; in addition, the amplitude and frequency of the random perturbation signal can be dynamically adjusted according to the patient's real-time physiological state, such as increasing the perturbation amplitude when autonomic nervous activity decreases, and reducing the perturbation intensity when the nervous system is overexcited, so as to achieve fine-grained control of the light acupuncture stimulation output, ensuring that the entire treatment process has both the regularity of rhythm synchronization and the naturalness of physiological fluctuations.

[0035] By dynamically adjusting the light stimulation rhythm and linking it with the human body's autonomic nervous state in real time, precise balance control of the excitability of the autonomic nervous system can be achieved. During the light acupuncture treatment process, the control system first collects the user's physiological rhythm data through a multi-channel physiological signal monitoring device, including heart rate variability, respiratory rate, pulse waveform, myoelectric rhythm, etc. The system calculates the minimum common beat of multiple rhythms based on the collected data as the basic time benchmark for light stimulation output. Whenever the minimum common beat is triggered, the control system not only performs light acupuncture stimulation output, but also synchronously evaluates the current autonomic nervous state. The evaluation of the autonomic nervous state includes real-time judgment of the excitability of the sympathetic and parasympathetic nerves. Monitoring indicators may include the LF / HF ratio in heart rate variability analysis, skin electrical response, respiratory pattern changes, and pulse wave amplitude. If the autonomic nervous system is detected to have an excitatory trend, such as a continuous increase in heart rate, rapid breathing, or decreased skin resistance, the control system will determine that the sympathetic nervous system is overactivated. If the autonomic nervous system is detected to have an inhibitory trend, such as a slow heart rate, shallow breathing, or a weakened pulse waveform, the control system will determine that the parasympathetic nervous system is overly dominant. For the above states, the control system The subsequent light stimulation rhythm is dynamically adjusted, and real-time balance control of excitation is achieved by adjusting the time interval between stimulation pulses. Specifically, in the state of autonomic nervous system hyperexcitation, the control system prolongs the time interval between adjacent light stimulations, reduces the frequency of light stimulation, gives the nervous system recovery and buffer time, reduces the neural load, and prevents adverse reactions caused by sympathetic overactivation; in the state of autonomic nervous system inhibition, the control system shortens the time interval between adjacent light stimulations, moderately increases the stimulation frequency, prompts the nervous system to recover excitement, and improves the balance between sympathetic and parasympathetic. The adjustment process is closed-loop control. The control system dynamically adjusts the rhythm according to the real-time autonomic nervous state when each minimum common beat is triggered, continuously monitors and corrects the stimulation output rhythm, achieves balanced guidance of autonomic nervous function, avoids long-term fixed stimulation of the nervous system by a single frequency or rhythm, and ensures that the autonomic nervous excitability is maintained within a reasonable fluctuation range during the entire light acupuncture treatment process, so as to achieve the therapeutic effect of promoting the stability of autonomic nervous function and improving the balance state in the body.

[0036] Example 1: Combined with attachment Figure 4In this example, a 35-year-old female patient, Ms. Li, complained of long-term insomnia, anxiety, and chest tightness. A doctor employed a light acupuncture control method for interference quiet zone suppression. Based on Traditional Chinese Medicine (TCM) syndrome differentiation, the primary acupoints selected for treatment were Shenmen (HT7) and Neiguan (PC6). However, since some patients experience hypersensitivity to certain secondary acupoints (such as Shaohai (HT3) on the heart meridian) during light acupuncture, clinical efforts are underway to suppress the potential for unwanted stimulation of these acupoints. Therefore, this example focuses on selective suppression of the Shaohai acupoint. During operation, the control system of the treatment device first retrieves a 3D coordinate image of Ms. Li's body surface. Using structured light combined with infrared scanning, the center of the Shaohai acupoint's skin surface is measured at (X=72.4mm, Y=18.2mm, Z=4.5mm), the target coordinate point for establishing the interference quiet zone. The control system configured the device to use two laser beams, each with a wavelength of 808nm and 812nm, for cross-irradiation, creating a frequency-difference interference condition. The two optical paths directed the target area at a 20-degree cross-angle. Initially, the control system simulated the distribution of interference fringes projected onto the body surface and found that the minimum power point in the interference quiet zone was located at (X=71.8mm, Y=17.5mm, Z=4.3mm), with a deviation of approximately 0.9mm from the center of the target acupoint. Therefore, the system initiated a real-time phase calibration mechanism, adjusting the phase of Laser 2 by 0.38π and fine-tuning the angle of incidence to 19.2 degrees. After further calculation, the minimum power point in the interference quiet zone moved to (X=72.4mm, Y=18.2mm, Z=4.5mm), with an error within ±0.1mm, meeting the acupoint coverage standard. The control system displayed the interference field intensity distribution curve in real time. The optical power at the minimum point was 0.003mW, far below the target illumination intensity lower limit of 10mW, and thus within the effective inhibition zone. After that, during the entire light acupuncture treatment cycle, each main acupoint irradiation lasted for 3 minutes. The system ensured that Shaohai acupoint was always at the center of the minimum power landing point in the interference quiet zone, no effective light energy penetrated, and no nerve activation occurred in the secondary acupoints. After receiving 5 treatments, Li reported that the tingling sensation in the secondary acupoint area had completely disappeared, the irradiation sensation in the main acupoint area was obvious, his sleep improved, and his heart rate stability increased.

[0037] To further improve the dynamic adaptability of treatment, the doctor activated multiple advanced control strategies during the sixth treatment session to achieve continuous suppression and dynamic rotational suppression management of the Shaohai acupoint. Because Li had experienced acupoint coordinate drift due to body position fine-tuning and tissue stress during previous treatment, the system first activated the interference fringe dynamic adjustment mode based on physiological state feedback during this treatment. Before treatment began, the system collected real-time skin resistance, microcirculatory blood flow, and temperature gradient in the Shaohai acupoint area. Initial measurements showed a skin resistance of 450 kΩ, a microcirculatory blood flow (laser speckle contrast) of 5.8 PU (Perfusion Units), and a temperature gradient of 0.6°C (the acupoint area was 0.6°C higher than the surrounding temperature). During the continuous irradiation process, it was detected that Mr. Li was sweating slightly due to autonomic nervous excitement, his skin resistance dropped to 380kΩ, his microcirculation increased to 7.2PU, and the temperature gradient changed to 0.9℃. These changes caused slight expansion of the local tissue and displacement of the surface contour coordinates, causing the real-time coordinates of Shaohai acupoint to shift from (X=72.4mm, Y=18.2mm, Z=4.5mm) to (X=72.7mm, Y=18.5mm, Z=4.8mm). The control system immediately triggered the interference fringe phase adjustment algorithm based on the physiological status data, adjusting the phase of laser 2 from Dynamically adjust to , and fine-tune the incident angle by 0.5 degrees so that the minimum power landing point in the interference quiet zone is re-locked at the new acupoint center position, ensuring that the suppression window completely covers the acupoint area and avoiding interference suppression failure caused by physiological fluctuations.

[0038] At the same time, considering that there are certain optical scattering differences in Li's subcutaneous tissue, especially the thin fat layer and high blood vessel density in the inner elbow area, the refractive index of the tissue varies in the local area. The control system calls the built-in tissue optical database and sets the subcutaneous scattering coefficient to The refractive index difference is estimated to be between 1.38 and 1.41. The system corrects the phase drift caused by the laser at the tissue interface through real-time OCT (optical coherence tomography) feedback, compensates for the optical path deviation of 0.12mm, and further optimizes the spatial distribution model of the interference fringes, so that the actual position of the interference quiet zone inside the tissue is highly matched with the preset model, reducing the focus error caused by scattering and refraction, and improving the spatial positioning accuracy of acupoint inhibition.

[0039] In order to prevent tissue heat accumulation or nonlinear biological effects caused by tiny residual light fields during long-term irradiation, the control system adopts a polarization state control strategy in the power management of the interference quiet zone. The two laser beams are set to horizontal polarization and vertical polarization respectively, forming mutually perpendicular orthogonal polarization states, so that the residual light field energy in the interference quiet zone is reduced to the theoretical limit. The measured residual power is further reduced from 0.003mW in the unpolarized state to 0.0008mW, which effectively reduces the tissue absorption rate and avoids side effects.

[0040] In addition, considering that other non-target acupoints of Li, such as Quchi (LI11) and Jianyu (LI15), are also easily covered by light when some body positions change, the control system activated the sequential rotation suppression function of the interference quiet zone during this treatment. The system sets the interference fringes to complete a position switch every 30 seconds, and rotates between Quchi, Jianyu and Shaohai points in sequence according to the preset trajectory, ensuring that multiple non-treatment acupoints are in the minimum power landing point of the interference quiet zone in sequence.

[0041] Taking Shaohai acupoint as the first point, the interference quiet zone is covered from 0 seconds to 30 seconds (X=72.7mm, Y=18.5mm, Z=4.8mm), then transferred to Quchi acupoint (X=68.3mm, Y=12.5mm, Z=6.0mm), covered from 30 seconds to 60 seconds, and then transferred to Jianyu acupoint (X=65.1mm, Y=9.8mm, Z=7.2mm), covered from 60 seconds to 90 seconds. After 90 seconds, the technique is cycled back to Shaohai acupoint, forming a dynamic optical inhibition rhythm, which not only prevents tissue adaptability caused by single-point inhibition, but also maintains the safety of the overall treatment process.

[0042] After this round of treatment, Li reported that the sensitivity of the secondary acupoints disappeared, and the needle sensation of the main acupoints Shenmen and Neiguan was obvious. The heart rate dropped from 83 beats / minute before treatment to 76 beats / minute, and the HRV (heart rate variability) increased from a standard deviation of 30ms to 42ms. The feedback from the sleep questionnaire improved, and there was no obvious discomfort during the entire treatment process.

[0043] Example 2: Combined with attachment Figure 5 Based on Example 1, a rhythm differential resynchronization control scheme is adopted to regulate the light stimulation output through the minimum common beat to achieve neural regulation of multi-system rhythm coordination. Before Li's treatment, the control system collected four physiological rhythm signals in real time: heart rate signal, respiratory rate signal, pulse wave signal and electromyographic rhythm signal. The initial monitoring data showed that the heart rate was 72 beats / minute, the basic period was 0.833 seconds, the respiratory rate was 18 beats / minute, the basic period was 3.333 seconds, the pulse wave corresponded to the heart rate synchronization, and the period was also 0.833 seconds. The electromyographic rhythm fluctuated slowly in the relaxed state, and the basic period was 1.6 seconds. The control system converts the above period into a time series, establishes a rhythm time reference, enters the minimum common beat calculation link, and adopts an innovative rhythm superposition function. The specific formula is as follows: in, , corresponding to heart rate, respiration, pulse, and electromyography, respectively. 、 、 、 (Unit: seconds), initial phase offset Set to 0, indicating that differential resynchronization is not introduced, the attenuation coefficient Initially set to 0.5, the unit is the reciprocal of the second, which means that the system gradually reduces the weight of the data in the past 2 seconds to about 37%. The control system substitutes the rhythm data collected in real time into the calculation and sets the integration at t=10 seconds. The numerical calculation example of the integration result is as follows: Take a small time step Seconds for discrete integration; In the interval [0,10], the system accumulates integrals; During the overlapping period of heart rate and pulse wave, Forming a strong resonance; The alternating influence of myoelectric signals and respiratory signals makes It is extremely small at some time points, but when the rhythms are locally aligned on the time axis, the superposition value reaches a peak; Attenuation Factor The effect is that the data of the last 2 seconds has a greater weight on the points, preventing the dominance of long-term historical data.

[0044] After integral calculation, it is found that at t=10 seconds, The local maximum value reached 0.76 (normalized to a range of 0-1). The control system determined that this was the rhythmic synergistic resonance point and immediately triggered the light acupuncture output pulse. The single pulse width was set to 50ms and the pulse power was 60mW / cm². To prevent a single rhythm from dominating, the system continued to implement differential resynchronization control. Analysis found that Li's breathing process had unstable rhythm, some respiratory cycles were prolonged, and the electromyographic cycle fluctuated. The system dynamically adjusted the phase offset based on real-time data. , in the next round of calculation, the respiratory rhythm Set to Deviation, myoelectric rhythm Set to After adjustment and recalculation, it was found that the time node of the rhythm synergy peak shifted slightly forward, and the stimulation output time shifted from Seconds ahead seconds, effectively avoiding the stimulation delay caused by respiratory fluctuations, while making the stimulation rhythm form an alternating stimulation of sympathetic and parasympathetic. Taking a continuous 5-minute treatment as an example, the system captures a local maximum every 4.5 to 5 seconds. , output light stimulation pulses, triggering a total of 60 pulses. Li felt that his breathing gradually slowed down, his heart rate gradually decreased from 82 beats / min before treatment to 74 beats / min, and his heart rate variability SDNN increased from 30ms to 45ms, indicating that his autonomic nervous function was improved. The feasibility of the rhythm differential resynchronization control scheme was verified by actual data substitution and dynamic phase control. The phase shift can be adjusted within the range of 0.3 to 1.0 according to the patient's autonomic nervous system sensitivity. Available in to Flexible settings ensure the physiological compatibility and individual adaptability of the system.

[0045] During Li's continued light acupuncture treatment, based on patient feedback and physiological monitoring data, the decision was made to implement an advanced rhythm differential resynchronization control strategy in subsequent sessions to further optimize treatment efficacy and reduce adaptive nervous system responses. Although Li's overall sleep quality improved after the initial minimal common beat stimulation sessions, heart rate monitoring data from some nights showed a persistent tendency toward sympathetic nervous system hyperactivity. Frequency-domain analysis of HRV (heart rate variability) showed an elevated LF / HF ratio (approximately 2.8, compared to a normal range of 1.5-2.0). To this end, the control system first performed instantaneous fluctuation weighting on the baseline rhythm data. For example, during one treatment session, Li's heart rate cycle was recorded to be 0.85 seconds (approximately 70 beats / minute), his respiratory cycle was 3.6 seconds (approximately 16.6 beats / minute), his pulse wave period was 0.85 seconds, and his electromyographic rhythm was 1.8 seconds. Since the current goal is to reduce sympathetic hyperactivity, the doctor increases the weight of respiratory rhythm from the standard value of 1.0 to 1.5, sets the weight of heart rate to 0.8, pulse wave to 0.8, and myoelectric rhythm to 1.0. The control system uses a weighted rhythm superposition function: in, is the weighting factor, heart rate ,breathe ,pulse , electromyography , Through the above calculation, the system captures Second, Second, Seconds, Reaching a local maximum indicates the emergence of a rhythmic synergistic resonance node. The system should have directly output a light stimulation pulse, but in order to avoid the neural fixation reaction caused by a single rhythm lock, the control system actively implements phase shifting within each cycle, offsetting the stimulation output time from the peak of the heart rate rhythm. , offset from respiratory trough value , forming an alternating stimulation pattern. For example, The pulse should be output at 12.05 seconds, but because the heart rate rhythm has a tendency to accelerate in the short term, the system detects that the heart rate has increased from 70 beats / minute to 74 beats / minute, so the phase offset is dynamically adjusted to delay the stimulation time by 0.05 seconds to 12.05 seconds, so that the light stimulation slightly avoids the heart rate peak and reduces the sympathetic excitation load; At 17.4 seconds, the respiratory cycle suddenly lengthened, and the system monitored the breathing from 3.6 seconds to 4 seconds. The control system determined that the autonomic nervous system gradually entered the parasympathetic dominant position based on the trend, and appropriately advanced the stimulation by 0.1 seconds to 17.4 seconds to form an alternating guidance of the autonomic nervous system. At the same time, during the entire rhythm differential resynchronization process, the control system superimposed the perturbation random noise, and the random perturbation range was set to seconds, ensuring that each output cycle contains unpredictable small time changes, avoiding neural blunting caused by long-term monotonous stimulation. Taking a 5-minute treatment as an example, the system outputs 60 pulses in total. The time intervals between each pulse are not completely equidistant, and the interval range fluctuates between 4.5 seconds and 5.2 seconds, so that Li's nervous system is always in a low-intensity uncertain stimulation environment, effectively preventing adaptation. Finally, the control system evaluates the autonomic nervous state in real time at each minimum common beat output, and monitors that during the treatment process, Li's heart rate gradually decreases from the initial 74 beats / minute to 68 beats / minute, and the LF / HF ratio decreases from 2.8 to 1.9, indicating that the sympathetic-parasympathetic balance is gradually restored; when the system monitors that the heart rate is stabilizing, the control system extends the stimulation output interval from the original average of 4.7 seconds to 5.5 seconds, reducing the stimulation frequency, further protecting the parasympathetic dominant state, and avoiding over-excitation.

1. A method for controlling light acupuncture, characterized in that include: The control system continuously applies multiple light stimulation pulses below the nerve excitation threshold to cause the target acupuncture point nerve to enter a subcritical energy storage state through the superposition of postsynaptic membrane potential. When a slight jump in the electrical response of the aforementioned target acupuncture point is detected, the control system increases the laser output intensity and emits a directional threshold-crossing pulse to trigger nerve discharge. During the subcritical stimulation process, the control system determines the main axis direction of local tissue fibers by detecting the time difference of the subcutaneous tissue micro-oscillation response, and adjusts the laser incident angle in the subsequent threshold-crossing pulse to allow the light beam to penetrate along the main axis direction to induce compliant tissue resonance.
