Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a method and device for intelligent reshaping of cervical curvature. Background Technology

[0002] Cervical spondylosis has become a common and prevalent disease in modern society, especially among office workers and students who spend long hours at their desks, and it is showing a trend towards affecting younger people. One of its main pathological manifestations is the straightening or even reversal of the cervical spine's physiological curvature. A normal cervical spine physiological curvature (lordosis) is crucial for maintaining cervical spine stability and cushioning head pressure.

[0003] Current cervical spine assistive devices and treatments have the following shortcomings: Traditional neck braces are mostly fixed structures that can only provide static support and immobilization. They lack the ability to dynamically monitor and actively correct physiological curvature, resulting in poor comfort during long-term wear and failing to meet the needs of users in daily scenarios such as work and study.

[0004] Traction equipment: Most of them are large, fixed equipment, which are not portable and have a single traction method, making it difficult to achieve intermittent thrust (referring to joint mobilization techniques) or real-time, personalized dynamic adjustment.

[0005] Insufficient intelligence: Most existing products lack the function of real-time monitoring of cervical curvature, and cannot make intelligent interventions based on the user's actual posture and curvature changes, nor can they provide scientific wearing advice.

[0006] Therefore, there is an urgent need in the market for an intelligent neck brace that integrates real-time monitoring and dynamic correction to effectively assist people with mild sub-health conditions in restoring the physiological curvature of their cervical spine, improving the correction effect and user experience. Summary of the Invention

[0007] This invention provides an intelligent method for reshaping cervical curvature, which addresses the shortcomings of traditional static support and blind traction devices in existing technologies. It combines non-invasive surface monitoring with a clinical curvature conversion model, enabling real-time, accurate assessment and dynamic, adaptive closed-loop correction of cervical physiological curvature.

[0008] This invention provides a method for intelligent reshaping of cervical curvature, comprising the following steps.

[0009] The position information of the upper positioning point, lower positioning point and center measurement point is collected in real time by position sensor and force sensor. The arc geometric parameters of the cervical spine are determined based on the position information of the three points. The arc geometric parameters correspond to the curvature shape of the body surface behind the wearer's cervical spine. Based on the geometric parameters of the circular arc, the physiological curvature value is obtained by conversion using the cervical curvature conversion model. When the current mode is dynamic adjustment mode, when the physiological curvature value is detected to exceed the first preset threshold, a fine-tuning force is applied through the thrust mechanism until the wearer's physiological curvature value is adjusted to the preset range; In the current traction mode, the real-time thrust value is calculated based on the physiological curvature value through an intelligent control algorithm; the thrust mechanism then applies the thrust based on the real-time thrust value.

[0010] The intelligent reshaping method for cervical curvature provided by the present invention further includes: When the current mode is the auxiliary mode, when the user's preset action is detected, a forward thrust is applied through the thrust mechanism; and the relative position of C1 and T1 is maintained within the second preset threshold through the C1-T1 relative fixing mechanism.

[0011] According to the present invention, a method for intelligent reshaping of cervical curvature includes three-point position information: upper position information, lower position information, and center position information. The method collects the three-point position information (upper positioning point, lower positioning point, and center measurement point) in real time using position sensors and force sensors. Based on this three-point position information, the method determines the arc geometry parameters of the cervical spine, including: Position sensors placed on the upper part of the cervical spine collect the upper position information of the upper positioning point in real time. Position sensors placed in the lower cervical spine collect real-time position information of the lower positioning point; The center position information of the center measurement point is collected in real time by using position sensors and force sensors placed in the cervical curvature area. The chord length between the upper and lower positioning points is calculated based on the upper and lower position information. The sag of the center measurement point relative to the chord length is calculated based on the upper position information, lower position information, and center position information. The circular arc geometry parameters of the cervical vertebrae are determined based on the chord length and sagittal height.

[0012] According to the present invention, a method for intelligent reshaping of cervical curvature, before converting based on a cervical curvature conversion model according to arc geometric parameters to obtain the physiological curvature value, further includes: When the user is in a neutral position according to the preset standing or sitting posture, the intelligent reshaping system performs baseline calibration on the user and records the body surface geometric parameters to obtain the calibrated body surface geometric parameters. Based on the calibrated body surface geometric parameters and the collected sample data, a cervical curvature conversion model between the body surface geometric parameters and the actual cervical curvature is established.

[0013] According to the present invention, a method for intelligent reshaping of cervical curvature is provided, which calculates a real-time thrust value based on physiological curvature values ​​using an intelligent control algorithm; including: The deviation is calculated by comparing the physiological curvature value with the preset target curvature value. By using intelligent control algorithms, based on the mapping relationship between curvature deviation and corrective thrust, the real-time thrust value is obtained by calculating the amount of deviation.

[0014] According to the present invention, a method for intelligent reshaping of cervical curvature is provided, wherein the thrust mechanism is located at the rear of the cervical collar, corresponding to the region from the fourth to the fifth cervical vertebrae; the thrust mechanism includes a miniature linear push rod and a high-precision force sensor.

[0015] The present invention also provides an intelligent cervical curvature reshaping device, comprising the following modules: The arc parameter calculation module is used to collect the position information of the upper positioning point, lower positioning point and center measurement point in real time through position sensor and force sensor, and determine the arc geometric parameters of the cervical spine based on the position information of the three points; among them, the arc geometric parameters correspond to the curvature shape of the body surface behind the wearer's cervical spine; The physiological curvature value calculation module is used to convert the cervical curvature value based on the circular arc geometric parameters and the cervical curvature conversion model to obtain the physiological curvature value. The dynamic adjustment module is used to apply a fine-tuning force through the thrust mechanism when the physiological curvature value exceeds the first preset threshold when the current mode is dynamic adjustment mode, until the wearer's physiological curvature value is adjusted to the preset range. The traction correction module is used to calculate the real-time thrust value based on the physiological curvature value through an intelligent control algorithm when the current mode is traction mode; and to apply the thrust through the thrust mechanism based on the real-time thrust value.

[0016] This invention also provides a cervical curvature intelligent reshaping system, comprising a lightweight streamlined main body, a three-point mechanical support structure, a real-time monitoring module, a dynamic thrust mechanism, an intelligent control module, and a human-computer interaction module; the intelligent control module implements any of the above-mentioned cervical curvature intelligent reshaping methods; The lightweight, streamlined main body is made of flexible composite materials. The three-point biomechanical support structure includes the posterior neck support point, the mandibular support point, and the suprasternal notch support point; The real-time monitoring module includes position and force sensors integrated on the support point; the dynamic thrust mechanism is a miniature linear actuator used to apply thrust to the C4-C5 vertebral body. The human-computer interaction module includes a manually adjustable mechanical knob and / or a wireless communication unit; the human-computer interaction module is integrated on the side of the neck brace for quick adjustment of support intensity or mode switching.

[0017] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement any of the above-described intelligent cervical curvature reshaping methods.

[0018] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the intelligent reshaping method for cervical curvature as described above.

[0019] The present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the cervical curvature intelligent reshaping method as described above.

[0020] The intelligent cervical curvature reshaping method provided by this invention collects the position information of three points—upper positioning point, lower positioning point, and center measurement point—in real time through position sensors and force sensors. Based on this three-point position information, the arc geometric parameters of the cervical spine are determined. According to the arc geometric parameters, a cervical curvature conversion model is used to convert the curvature to obtain the physiological curvature value. In the current dynamic adjustment mode, when the physiological curvature value exceeds a first preset threshold, a fine-tuning thrust is applied through a thrust mechanism until the wearer's physiological curvature value is adjusted to the preset range. In the current traction mode, an intelligent control algorithm calculates the real-time thrust value based on the physiological curvature value. The thrust mechanism applies the thrust based on the real-time thrust value. Compared with the static support of traditional cervical braces and the blind traction of existing traction devices, this invention combines non-invasive surface monitoring with a clinical curvature conversion model, achieving real-time, accurate assessment and dynamic, adaptive closed-loop correction of the cervical spine's physiological curvature.

[0026] Figure 5 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] The following is combined with Figures 1 to 5 This invention is described.

[0029] Figure 1 This is a flowchart illustrating the intelligent cervical curvature reshaping method provided by the present invention, as shown below. Figure 1 As shown, the method includes the following: Step 101: Collect the position information of the upper positioning point, lower positioning point and center measurement point in real time through position sensor and force sensor, and determine the arc geometric parameters of the cervical spine based on the position information of the three points; where the arc geometric parameters correspond to the curvature shape of the body surface behind the wearer's cervical spine.

[0030] In step 101 above, the present invention provides a dynamic intelligent neck brace system based on biomechanical closed-loop control, which aims to solve the problems of cervical spine sub-health and straightening of physiological curvature caused by poor posture in modern people.

[0031] The intelligent neck brace provided by this invention mainly consists of a lightweight streamlined body, a three-point mechanical support structure, a real-time monitoring module, a C4-C5 dynamic thrust mechanism, an intelligent control module, a human-computer interaction module, and a safety emergency stop mechanism.

[0032] The human cervical spine has a physiological curvature, a streamlined arc. The entire frame structure of the neck brace needs to be aesthetically pleasing, conform to the curvature of the cervical spine, and serve as a carrier for various electronic components. A lightweight, streamlined body can meet these requirements.

[0033] Optionally, the three-point location information includes upper location information, lower location information, and center location information; step 101 includes steps B1 to B6: Step B1: Collect the upper position information of the upper positioning point in real time by using position sensors placed on the upper part of the cervical spine.

[0034] Step B2: Collect the lower positioning information of the lower positioning point in real time by using a position sensor placed in the lower cervical spine.

[0035] Step B3: Collect the center position information of the center measurement point in real time by using position sensors and force sensors placed in the cervical curvature area.

[0036] Step B4: Calculate the chord length between the upper and lower positioning points based on the upper and lower position information.

[0037] Step B5: Calculate the sag of the center measurement point relative to the chord length based on the upper position information, lower position information, and center position information.

[0038] Step B6: Determine the arc geometry parameters of the cervical vertebrae based on the chord length and sagittal height.

[0039] In steps B1 to B6 above, the real-time monitoring module utilizes upper and lower non-invasive high-precision position sensors that contact the wearer's body surface at the rear of the neck brace, with a central integrated position sensor and force sensor forming a three-point geometric system. These three points are typically located behind the cervical spine. For example: Upper positioning point: corresponding to the upper cervical spine (e.g., near the C2 spinous process); Lower positioning point: corresponding to the lower cervical spine (e.g., near the C7 spinous process); Central measurement point: corresponding to the area with the most significant curvature change (e.g., the C4-C5 spinous process region), which is also the contact point of the C4-C5 dynamic thrust mechanism.

[0040] An arc can be determined in real time by measuring the chord length, or fixed distance, between the upper and lower positioning points, and the sagitta, or depth, of the center measuring point relative to this chord. The geometric parameters of this arc, such as the radius of curvature or sagitta, directly reflect the curvature of the wearer's cervical spine, indicating normal lordosis, straightening, or reverse curvature. Figure 2 As shown, Figure 2 This is a schematic diagram of the three points determining an arc in the intelligent cervical curvature reshaping method provided by the present invention.

[0041] Optionally, before step 102, steps C1 to C2 are also included: Step C1: When the user is in a neutral position according to the preset standing or sitting posture, the intelligent reshaping system performs baseline calibration on the user and records the body surface geometric parameters to obtain the calibrated body surface geometric parameters.

[0042] Step C2: Based on the calibrated body surface geometric parameters and the collected sample data, establish a cervical curvature conversion model between the body surface geometric parameters and the actual cervical curvature.

[0043] In steps C1 to C2 above, in order to ensure that the body surface measurements have clinical significance, it is necessary to establish a conversion model between them and the gold standard of X-ray films, and to establish a conversion formula for the normal range of curvature in normal populations.

[0044] Neutral position calibration specifically involves the system performing baseline calibration when the user is in a neutral position, such as a naturally relaxed standing or sitting posture, recording the body surface geometric parameters at this time, and correlating them with the normal curvature range.

[0045] The transformation model is specifically established by studying a large amount of sample data to create a nonlinear regression model between body surface geometric parameters and actual cervical curvature. This could be a multinomial fitting or machine learning model. This model transforms real-time body surface measurements into clinically comparable physiological curvature values, thereby enabling accurate assessment of cervical curvature status.

[0046] Step 102: Based on the circular arc geometric parameters, the cervical curvature conversion model is used to convert the cervical curvature values ​​to obtain the physiological curvature values.

[0047] Step 103: When the current mode is dynamic adjustment mode, when the physiological curvature value is detected to exceed the first preset threshold, a fine-tuning force is applied through the thrust mechanism until the wearer's physiological curvature value is adjusted to the preset range.

[0048] In step 103 above, when the straightening or reversal of the cervical curvature is detected, the intelligent control module drives the C4-C5 dynamic thrust mechanism to apply steplessly adjustable thrust, dynamically adjusting the curvature to the normal range, and reminding the wearer through micro-vibration.

[0049] Step 104: When the current mode is traction mode, the real-time thrust value is calculated based on the physiological curvature value through the intelligent control algorithm; the thrust mechanism applies the thrust based on the real-time thrust value.

[0050] Optionally, in step 104, the real-time thrust value is calculated based on the physiological curvature value using an intelligent control algorithm; this includes steps D1 to D2: Step D1: Calculate the difference between the physiological curvature value and the preset target curvature value to obtain the deviation.

[0051] Step D2: Using an intelligent control algorithm, based on the mapping relationship between curvature deviation and corrective thrust, the real-time thrust value is calculated according to the deviation amount.

[0052] In steps D1 to D2 above, under traction mode, the C4-C5 thrust mechanism can achieve low-amplitude, high-frequency, intermittent thrust output, mimicking joint mobilization, to thrust the C4-C5 vertebral body to assist in restoring curvature.

[0053] The correction thrust is positively correlated with the curvature deviation, ensuring that the thrust is proportional to the correction requirement: the thrust F is determined by the deviation (θ_estimated - θ_target), i.e., F = g(|θ_estimated - θ_target|). The function g can be designed as proportional control, PID control, or other intelligent control algorithms.

[0054] When the system detects straightening of the spinal curvature (θ_estimated > θ_target), it increases the thrust F according to the control algorithm. When the curvature returns to the target value, the thrust decreases accordingly to avoid overcorrection. This achieves a closed-loop intelligent correction that integrates perception, decision-making, and execution, moving from open-loop correction.

[0055] Optionally, the thrust mechanism is located at the rear of the neck brace, corresponding to the area between the fourth and fifth cervical vertebrae; the thrust mechanism includes a miniature linear push rod and a high-precision force sensor.

[0056] Optionally, the intelligent cervical curvature reshaping method provided by the present invention further includes: Step A1: When the current mode is the auxiliary mode, when the user's preset action is detected, a forward thrust is applied through the thrust mechanism; and the relative position of C1 and T1 is maintained within the second preset threshold through the C1-T1 relative fixing mechanism.

[0057] In step A1 above, the neck brace structure allows the head to rotate left and right and flex laterally. In assisted movement mode, when the user performs head-raising and chin-retracting movements, the C4-C5 thrust mechanism applies forward thrust to the C4-C5 region while C1-T1 is relatively fixed, effectively assisting in the restorative movement of the cervical curvature.

[0058] This invention is the first to combine real-time cervical curvature monitoring with a dynamic thrust mechanism for C4-C5, achieving dynamic, precise, and personalized correction of the physiological curvature of the cervical spine. In particular, by drawing on the intermittent thrust technique of joint mobilization, it improves correction efficiency. With C1-T1 relatively fixed, this invention assists users in performing restorative movements of head retraction and C4-C5 forward thrust, ensuring the scientific validity and effectiveness of the exercise.

[0059] The intelligent cervical curvature reshaping method provided by this invention collects the position information of three points—upper positioning point, lower positioning point, and center measurement point—in real time through position sensors and force sensors. Based on this three-point position information, the arc geometric parameters of the cervical spine are determined. According to the arc geometric parameters, a cervical curvature conversion model is used to convert the curvature to obtain the physiological curvature value. In the current dynamic adjustment mode, when the physiological curvature value exceeds a first preset threshold, a fine-tuning thrust is applied through a thrust mechanism until the wearer's physiological curvature value is adjusted to the preset range. In the current traction mode, an intelligent control algorithm calculates the real-time thrust value based on the physiological curvature value. The thrust mechanism applies the thrust based on the real-time thrust value. Compared with the static support of traditional cervical braces and the blind traction of existing traction devices, this invention combines non-invasive surface monitoring with a clinical curvature conversion model, achieving real-time, accurate assessment and dynamic, adaptive closed-loop correction of the cervical spine's physiological curvature.

[0060] The intelligent cervical curvature reshaping device provided by the present invention is described below. The intelligent cervical curvature reshaping device described below and the intelligent cervical curvature reshaping method described above can be referred to in correspondence with each other.

[0061] Figure 3 This is a flowchart illustrating the intelligent cervical curvature reshaping device provided by the present invention, as shown below. Figure 2 As shown, the device includes the following: The arc parameter calculation module 301 is used to collect the position information of the upper positioning point, the lower positioning point and the center measurement point in real time through the position sensor and the force sensor, and determine the arc geometric parameters of the cervical spine based on the position information of the three points; wherein, the arc geometric parameters correspond to the curvature shape of the body surface behind the wearer's cervical spine.

[0062] The physiological curvature value calculation module 302 is used to convert the cervical curvature value based on the arc geometric parameters and the cervical curvature conversion model to obtain the physiological curvature value.

[0063] The dynamic adjustment module 303 is used to apply a fine-tuning force through the thrust mechanism when the physiological curvature value exceeds the first preset threshold when the current mode is dynamic adjustment mode, until the wearer's physiological curvature value is adjusted to the preset range.

[0064] The traction correction module 304 is used to calculate the real-time thrust value based on the physiological curvature value through an intelligent control algorithm when the current mode is traction mode; and to apply the thrust through the thrust mechanism based on the real-time thrust value.

[0065] The intelligent cervical curvature reshaping device provided by this invention collects real-time position information from three points—the upper positioning point, the lower positioning point, and the central measurement point—using position and force sensors. Based on this information, the arc geometry parameters of the cervical spine are determined. Using these parameters, a cervical curvature conversion model is used to obtain the physiological curvature value. In dynamic adjustment mode, when the physiological curvature value exceeds a first preset threshold, a fine-tuning force is applied via a thrust mechanism until the wearer's physiological curvature value is adjusted to the preset range. In traction mode, an intelligent control algorithm calculates the real-time thrust value based on the physiological curvature value. The thrust mechanism applies the thrust based on this real-time value. Compared to the static support of traditional cervical braces and the blind traction of existing traction devices, this invention combines non-invasive surface monitoring with a clinical curvature conversion model, achieving real-time, accurate assessment and dynamic, adaptive closed-loop correction of the cervical spine's physiological curvature.

[0066] The intelligent cervical curvature reshaping system provided by the present invention is described below. The intelligent control module in the intelligent cervical curvature reshaping system described below implements any of the above-mentioned intelligent cervical curvature reshaping methods.

[0067] like Figure 4 As shown, Figure 4 This is a schematic diagram of the cervical curvature intelligent reshaping system provided by the present invention.

[0068] This invention provides an intelligent cervical curvature reshaping system, comprising a lightweight streamlined main body, a three-point mechanical support structure, a real-time monitoring module, a dynamic thrust mechanism, an intelligent control module, and a human-computer interaction module; the intelligent control module implements any of the aforementioned intelligent cervical curvature reshaping methods. The intelligent reshaping system is the main operating procedure of the intelligent cervical brace, executing the intelligent cervical brace function.

[0069] The lightweight, streamlined main body is made of flexible composite materials.

[0070] The three-point biomechanical support structure includes the posterior neck support point, the mandibular support point, and the suprasternal notch support point.

[0071] The real-time monitoring module includes position and force sensors integrated on the support points; the dynamic thrust mechanism is a miniature linear actuator used to apply thrust to the C4-C5 vertebrae.

[0072] The human-computer interaction module includes a manually adjustable mechanical knob and / or a wireless communication unit; the human-computer interaction module is integrated on the side of the neck brace for quick adjustment of support intensity or mode switching, enabling autonomous control without the need for an app.

[0073] Specifically, the lightweight, streamlined body is integrally molded using flexible composite materials (such as medical-grade silicone and carbon fiber skeleton) to achieve a lightweight and streamlined design that conforms to ergonomics, ensuring wearing comfort and scenario-friendliness.

[0074] The three-point mechanical support structure follows the three-point support principle, including the posterior neck support point, the mandibular support point, and the suprasternal notch support point, forming a stable mechanical base.

[0075] The C1-T1 relatively fixed mechanism and the support frame design ensure that the relative position of the first cervical vertebra (C1) and the first thoracic vertebra (T1) remains stable during the correction process, serving as the reaction point of the corrective force.

[0076] The C4-C5 dynamic thrust mechanism (core correction unit) is located at the rear of the cervical collar, corresponding to the fourth and fifth cervical vertebrae (C4-C5). It consists of a miniature linear actuator (or miniature pneumatic actuator) and a high-precision force sensor, and is used to apply intermittent or continuous thrust.

[0077] The three-point mechanical support structure is a classic theory in orthopedic mechanics, used to adjust the curvature of the cervical spine. The three support points are the posterior neck support point, the mandibular support point, and the suprasternal notch support point. The three positioning points also include the posterior neck support point, the mandibular support point, and the suprasternal notch support point; the three support points and the three positioning points are respectively located in three-dimensional space. This invention uses support points to describe force adjustment and positioning points and measurement points to describe real-time curvature recognition. This invention adopts a lightweight, streamlined design, integrating real-time monitoring, dynamic correction, and multi-mode intelligent adjustment into a smart neck brace to effectively assist individuals with mild sub-health conditions in restoring the physiological curvature of the cervical spine, improving the corrective effect and user experience.

[0078] This invention enables intelligent control and human-computer interaction. Specifically, it includes: Multi-mode intelligent adjustment. Specifically, the working modes are: Light support with real-time monitoring and subtle reminders for poor posture; Traction mode: Activates the C4-C5 thrust mechanism for intermittent thrust correction or continuous traction, with adjustable intensity and frequency; Timed fixation mode: Provides stable and strong support, suitable for specific treatment situations.

[0079] Human-computer interaction module. Specifically, a manually adjustable mechanical knob: integrated on the side of the neck brace, used for quick adjustment of support intensity or mode switching, enabling independent control without the app. Mobile app control: provides real-time data monitoring, mode switching, personalized parameter settings, and, based on wearing data and health algorithms, offers scientific wearing time recommendations and exercise guidance.

[0080] Emergency stop button. Specifically, it is located in a prominent position on the neck brace. Pressing it immediately releases all thrust / traction and enters a zero-support free mode, ensuring that the user can quickly dismount in any uncomfortable situation, thus improving safety.

[0081] This invention features a lightweight, streamlined design and offers dual control via mechanical knobs and an app, enabling multi-mode intelligent adjustment and significantly improving comfort and usability. It also includes a safety emergency stop button and an overload protection mechanism to ensure users can quickly release all external forces in emergencies, guaranteeing safe operation.

[0082] To further explain the present invention, the following specific embodiments are provided.

[0083] Structure and Materials. The neck brace uses a high-molecular polymer (such as polycarbonate PC or nylon PA) as its framework, with an outer layer wrapped in skin-friendly, breathable, medical-grade silicone. The streamlined design ensures lightweight (total weight not exceeding 200 grams) and aesthetic appeal. The contact surfaces of the three-point support structure use memory foam or air cushions to distribute pressure and improve comfort.

[0084] Real-time monitoring module. Real-time monitoring sensors include: IMU sensors: Integrated at the occipital support point and C7 support point respectively, used to accurately measure the relative posture angles of the head and torso.

[0085] Flexible pressure sensors: Embedded at all support points and the contact surfaces of the C4-C5 thrust mechanisms, these sensors monitor pressure distribution and thrust magnitude in real time. The intelligent control module (microprocessor) fuses IMU and pressure data using algorithms such as Kalman filtering to calculate the cervical spine physiological curvature index with an accuracy of ±2 degrees.

[0086] C4-C5 dynamic thrust mechanism.

[0087] The C4-C5 dynamic thrust mechanism is the core of this invention. It uses a linear push rod driven by a micro stepper motor with a stroke of about 5-10mm and an adjustable thrust range (e.g., 5N-30N).

[0088] Intermittent thrust is achieved as follows: In traction mode, the microprocessor controls the stepper motor to apply a small stroke thrust of 2mm-5mm at a frequency of 0.5Hz-2Hz, simulating the level 1-2 manipulation in joint mobilization surgery, effectively loosening the joint and restoring its curvature.

[0089] Dynamic adjustment is achieved when the curvature monitoring value exceeds the normal range. The push rod makes stepless adjustments at an extremely slow speed of 1mm / s until the curvature returns to normal, thus achieving dynamic balance.

[0090] Intelligent control and software implementation. The intelligent control module uses a low-power microprocessor (such as the ARM Cortex-M series) and has built-in multi-mode control algorithms.

[0091] APP control terminal: Connects to a mobile APP via Bluetooth Low Energy (BLE). The APP provides user data management, mode selection, correction intensity setting, wearing time statistics and scientific suggestions (e.g., it is recommended to wear for no more than 4 hours a day in work mode, and 15 minutes each time in traction mode, 3-5 times a week).

[0092] Mechanical knob: The knob connects to the encoder to enable quick mode switching (short press) and stepless adjustment of support force (rotation), ensuring that users can control the device independently even when it is inconvenient to use their mobile phones.

[0093] Emergency Stop: The emergency stop button is directly connected to the power cut-off circuit of the thrust mechanism, enabling rapid power-off at the hardware level and ensuring maximum safety.

[0094] The specific implementation process includes: Users wear the neck brace and select the mode via an app or a mechanical knob.

[0095] The real-time monitoring module collects data and calculates the cervical curvature.

[0096] The intelligent control module drives the C4-C5 thrust mechanism to perform dynamic adjustment or intermittent thrust correction based on the curvature value and the selected mode.

[0097] In working mode, if the posture is incorrect, the system will provide a reminder through the thrust mechanism or micro-vibration.

[0098] Users can press the emergency stop button at any time to release all external forces.

[0099] Through the above technical solution, this invention achieves intelligent, dynamic, and precise correction of the physiological curvature of the cervical spine, providing an efficient, comfortable, and safe rehabilitation aid for people with sub-healthy cervical spine conditions.

[0100] Figure 5 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 5 As shown, the electronic device may include a processor 810, a communications interface 820, a memory 830, and a communication bus 840. The processor 810, communications interface 820, and memory 830 communicate with each other via the communication bus 840. The processor 810 can call logical instructions from the memory 830 to execute the intelligent cervical curvature reshaping method.

[0101] Furthermore, the logical instructions in the aforementioned memory 830 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods described in the various embodiments of the present invention. The aforementioned storage medium includes various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.
