Technical Field

[0001] The utility model relates to the field of scoliosis correction, in particular to a scoliosis correction arm with variable correction direction and a spinal correction device. Background Technique

[0002] Scoliosis refers to the lateral bending of one or several segments of the spine in the coronal plane away from the midline of the body, forming a spinal deformity with an arc. Usually, it is also accompanied by the rotation of the spine and the increase or decrease of the posterior or anterior protrusion in the sagittal plane. At the same time, there are also uneven left and right ribs, rotational tilt deformity of the pelvis, and abnormalities of the paravertebral ligaments and muscles.

[0003] Since the scoliosis angles, positions, and directions of scoliosis patients may vary, and the scoliosis condition may change during the correction treatment, patients need to change the correction direction and position in real time during spinal correction to adapt to the changes in scoliosis, so as to maintain the best correction effect. However, the existing spinal scoliosis correction devices do not have the ability to change the correction direction before and during spinal correction; or the correction structure is single and the angle change is small. For example, the Chinese patent with the application number 202021586664.8: A lateral correction mechanism for treating scoliosis. Neither of the above two methods can achieve the best correction effect. Therefore, how to overcome the above existing technical problems and defects has become the key problem to be solved.
