Description

Technical Field

[0001] This invention relates to the field of spinal correction technology, and in particular to an adaptive scoliosis correction device and method based on pulsed electromagnetic fields. Background Technology

[0002] Adolescent idiopathic scoliosis is a structural spinal deformity occurring in adolescents. Its core characteristic is a lateral curvature of the spine exceeding 10° in the coronal plane, possibly accompanied by spinal rotational deformities. The onset age is primarily concentrated in adolescence, between 10 and skeletal maturity (usually 16-18 years old), making it the most common type of scoliosis in children and adolescents, accounting for approximately 80% of all scoliosis cases. It not only causes spinal curvature, vertebral body and thoracic abnormalities, but can also hinder thoracic development, compress cardiopulmonary function, and induce cardiopulmonary dysfunction or even failure. The unbalanced posture affects appearance and severely impacts mental health, leading to problems such as low self-esteem and social difficulties.

[0003] Current diagnostic methods, especially in the early stages, rely heavily on the Adams flexion test and physical observation, which are subjective, difficult to quantify, and insensitive to atypical scoliosis. As the condition progresses, spinal X-rays can directly visualize the spinal structure and morphology, and accurately measure the Cobb angle. However, this method involves ionizing radiation, is costly, and inconvenient to operate, making it unsuitable for large-scale, high-frequency screening. After screening and diagnosis, current treatment interventions often recommend the Schroth method for early-stage patients, but recovery depends on the patient's self-discipline and adherence, making quantitative assessment difficult. In more advanced stages, bracing or even surgery is used. Bracing is custom-made, rigid, and requires prolonged wear, leading to poor patient compliance. Surgical treatment is often the final solution for poorly controlled scoliosis in the early stages, and is costly and carries certain risks. Therefore, developing a flexible wearable correction device for early screening, diagnosis, and intervention of adolescent idiopathic scoliosis, combining flexible electronics technology, would enable early screening and quantifiable intervention under comfortable wearing conditions. This would improve patient compliance and ensure efficacy, possessing significant medical and social value. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology by providing an adaptive scoliosis correction device and method based on pulsed electromagnetic fields. This device and method offer high wearing comfort and improved patient compliance; they are safe, non-invasive, and radiation-free; the measurement results are objective and quantifiable; the screening cost is low and convenient; they provide an active physical therapy method with strong treatment targeting; they enable personalized and adaptive treatment; and they allow for remote monitoring and risk warning.

[0005] The objective of this invention can be achieved through the following technical solutions: This invention provides a flexible wearable scoliosis correction device based on pulsed electromagnetic field adaptive correction, comprising: Flexible fabric carriers, including fabrics and elastic polymers, are used to fit and secure the device to the user's torso; A rigid support frame, set on the flexible fabric carrier, is made of high-performance composite materials, metal or engineering plastics, and is used to maintain the overall shape of the device. Multiple multifunctional units are distributed on the flexible fabric carrier, and each multifunctional unit includes an upper encapsulation layer, a coil layer, a pressure array layer and a lower encapsulation layer arranged from top to bottom. The controller is electrically connected to the multi-functional unit; The pressure array layer is used to detect pressure distribution data, and the coil layer is used to generate pulsed electromagnetic fields according to the instructions of the controller. The controller is configured to calculate the scoliosis angle based on the pressure distribution data and the user's body shape data, and control the coil layer to output pulsed electromagnetic fields with specific parameters for intervention treatment based on the calculation results.

[0006] Furthermore, the elastic polymer is one of foamed silicone rubber, ethylene propylene diene monomer (EPDM), polyurethane, or thermoplastic elastomer.

[0007] Furthermore, the rigid support frame is made of one of the following materials: carbon fiber reinforced material, graphene composite material, spring steel, titanium alloy, aluminum alloy, nylon, or modified polypropylene (PP).

[0008] Furthermore, the pressure array layer operates on a piezoresistive, piezoresistive, or magnetically sensitive principle, with a pressure measurement range of 0~50 kPa, a measurement accuracy within 5%, and a sensing unit density of 1-10 units / cm². 2 .

[0009] Furthermore, the pulsed magnetic field strength generated by the coil layer is 0.5~5mT, and the frequency is 0.1~100Hz.

[0010] Furthermore, the upper and lower encapsulation layers are made of breathable fabric or leather.

[0011] Furthermore, when the calculated scoliosis angle does not exceed the threshold, the control device remains in standby or off state.

[0012] Furthermore, the controller also includes a memory for recording the scoliosis angle, pulsed electromagnetic field stimulation parameters, and corresponding time series data.

[0013] Furthermore, the controller also includes a wireless communication module for uploading the recorded lateral bending angle, stimulation parameters, and time series data to a cloud server; the cloud server is configured to evaluate the intervention treatment effect, optimize the intervention treatment plan, and generate correction suggestions or risk warning information to send back to the controller when the data is abnormal.

[0014] This invention also provides a correction method for scoliosis based on a pulsed electromagnetic field adaptive flexible wearable orthosis device, comprising the following steps: S1: The user wears the device and inputs their personal body shape data; S2: The controller collects the detection data of the pressure array layer and calculates the scoliosis angle by combining it with body shape data; S3: If the lateral curvature angle is abnormal, the controller will control the coil layer of the corresponding multifunctional unit to output a pulsed electromagnetic field with specific parameters to stimulate the body according to the intervention treatment plan. S4: Record the lateral bending angle, stimulation parameters, and time series, and upload them to the cloud for analysis and feedback.

[0015] Compared with the prior art, the present invention has the following advantages: (1) High wearing comfort and improved patient compliance. Flexible fabrics (such as polyester fibers and elastic polymers) and flexible multifunctional units are used to replace traditional hard and bulky rigid braces. This significantly improves the comfort of wearing against the skin and reduces the risk of skin pressure and friction damage. Due to the improved comfort, especially for adolescent patients who need to wear them for a long time, their willingness to wear them and the duration of use (compliance) will be greatly improved, which is the primary prerequisite for ensuring the effectiveness of any orthodontic treatment program.

[0016] (2) Safe, non-invasive, and radiation-free, with objective and quantifiable measurement results, low screening cost, and high convenience. Measurements are performed using a flexible pressure array sensor, enabling radiation-free and non-invasive assessment of spinal morphology. This overcomes the ionizing radiation risks of X-ray examinations, making high-frequency, long-term follow-up monitoring possible, and is highly suitable for early screening and disease monitoring. Utilizing multi-point pressure distribution data combined with AI algorithms, the subjective judgment previously reliant on doctors' visual observation (such as the Adams test) is transformed into objective, quantifiable data (such as the scoliosis angle), improving the accuracy and consistency of diagnosis. Compared to X-ray examinations requiring specialized equipment and facilities, this device is lower in cost and simpler to operate, and is expected to enable large-scale screening in schools, communities, and other settings, achieving "early detection" of scoliosis.

[0017] (3) It provides an active physical therapy method with strong therapeutic targeting. It integrates pulsed electromagnetic field function, which is a non-invasive physical therapy. It assists in correction from a physiological level by stimulating osteoblast activity and improving local blood circulation, providing a new and active treatment method for early intervention of scoliosis, which surpasses the traditional passive fixation mode of braces. The device can accurately locate and apply electromagnetic stimulation according to the abnormal scoliosis segment determined by the pressure sensor to achieve personalized intervention.

[0018] (4) Achieving personalized and adaptive treatment, and enabling remote monitoring and risk warning. Through the cloud data platform, the system can record long-term changes in spinal curvature and treatment parameters, forming a personal electronic health record. Based on big data analysis, the efficacy can be dynamically evaluated and intervention plans optimized, making the treatment process more scientific by adaptively adjusting to changes in the patient's condition. Doctors or the system can remotely view the patient's rehabilitation data and generate timely risk warnings and rehabilitation guidance when abnormalities occur in the data, breaking the geographical and time limitations of traditional treatment and realizing full-process, intelligent health management.
