Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a spinal correction device. Background Art

[0002] Scoliosis / scoliosis refers to the lateral curvature of one or more segments of the spine, or a three-dimensional deformity of the spine accompanied by vertebral rotation, including abnormal sequences in the coronal, sagittal and horizontal planes. The normal spine should be a straight line when viewed from the back, and the two sides of the trunk should be symmetrical. Mild scoliosis usually does not cause obvious discomfort, and no obvious body deformity can be seen from the appearance. More severe scoliosis will affect the growth and development of infants or adolescents, causing body deformation. In severe cases, it can affect cardiopulmonary function and even involve the spinal cord, causing paralysis. Mild scoliosis can be observed, while severe cases require surgical treatment.

[0003] Scoliosis is common in adolescents, with an international incidence of 2% to 3%. In China, the incidence of scoliosis is as high as 5%. In clinical practice, the Cobb angle is often used to measure the severity of scoliosis. When scoliosis is at a certain severity (Cobb angle is greater than 20 degrees and less than 45 degrees), conservative treatment is appropriate. Specific training movements or correction devices are often used to apply corrective thrusts and rotational thrusts to different parts of the trunk of scoliosis patients, so that the scoliosis is relieved due to the force and maintained for a certain period of time. Using continuous thrust or intermittent thrust can achieve a certain therapeutic effect.

[0004] In the prior art, correction devices are mainly based on sitting posture correction, and also include some standing and lying correction methods. Correction and adjustment devices are mostly manual and can perform passive treatment. A few have biomechanical feedback and can perform active training and cooperate with three-dimensional ultrasound scanning to provide real-time feedback on the correction effect. Some devices have adjustable force point positions and seat positions, and are mostly frame structures. The spatial position adjustment range of these force-applying devices is not comprehensive enough, especially many force-applying devices only have basic position adjustment functions, such as simple height, lateral position or angle adjustment of the force-applying point, and cannot achieve force application at any target position within the three-dimensional spatial range of the treatment area, making it difficult to meet the treatment needs of different scoliosis patients.
