Background

Scoliosis is commonly called scoliosis, the spine of a normal person is a straight line from the back view, namely the coronal plane, the trunk is bilaterally symmetrical, and the international scoliosis society (SRS) considers that the Cobb angle of the spine is measured to be more than 10 degrees, so that the scoliosis can be diagnosed. Scoliosis causes back appearance deformity with associated dysfunction, severe patients can influence cardiopulmonary development due to secondary thoracic deformity, even cardiopulmonary failure, and the life quality of the patients is greatly reduced, so the scoliosis needs to be corrected according to the degree of the scoliosis. At present, the operation is an effective method for treating scoliosis, and a vertebral body segment needing to be corrected is determined according to the angle and the type of the scoliosis.

Because the spine of a human body has physiological curvature, the orthopedic rod needs to be prepared into a shape which accords with the physiological curvature, and the spine with the scoliosis deformity has a certain bending angle, so that a doctor needs to face a lot of difficulties in the process of placing the orthopedic rod, the spine deformity is a complex three-dimensional deformity, and the rotation of a vertebral body exists while the scoliosis, so that the requirement on the controllability of the correction operation is very high. The existing orthopedic tools are difficult to perform centrum removal rotation while correcting the lateral bulge, and the requirements on the orthopedic tools and the operation experience of operators are very high. Meanwhile, in the process of scoliosis surgery, a doctor needs to manually control one side fixing instrument after preliminary correction so as to conveniently fix the upper rod of the lateral pedicle screw and further correct the lateral pedicle screw. The process has very high experience requirements on operators, the manpower control is easy to change after being stressed and countered, and meanwhile, a large amount of physical strength of a surgeon can be consumed by long-time counterwork and force exertion, so that single operation failure in the operation can be caused, the correction accuracy is influenced, and the postoperative effect is not satisfactory and the possibility of secondary operation is caused.
