Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a magnetic repositioning device for scoliosis and its usage method. Background Technology

[0002] Scoliosis, a common spinal deformity, severely affects patients' posture, physiological function, and quality of life. Currently, commonly used scoliosis correction devices in clinical practice, such as traditional mechanical braces and traction devices, have many drawbacks. Mechanical braces typically use rigid frame structures, making it difficult to conform to the complex spinal morphology of patients, easily causing local pressure. This not only causes skin discomfort and pain but may also affect local blood circulation due to long-term pressure. Furthermore, the corrective force they apply is relatively harsh, making it difficult to achieve slow, gentle force adjustment, which is not conducive to gradual spinal correction. While traction devices can provide some stretching force, the magnitude of the force is difficult to control precisely. Excessive traction may damage spinal tissue, while insufficient force fails to achieve the desired corrective effect. Existing spinal correction devices struggle to achieve precise and gentle force control while ensuring corrective effectiveness. Therefore, developing a novel device that utilizes electromagnetic force to apply a slow and gentle force to the spine, effectively straightening it, is crucial for improving the safety and effectiveness of scoliosis correction.
