Spine operations such as thoracolumbar fracture posterior resection and internal fixation, vertebroplasty, kyphoplasty and the like are very common in clinic. With the improvement of the technology and the development of equipment, posterior minimally invasive surgery is increasingly used for clinically treating thoracolumbar fractures at present, and spine surgeries such as vertebroplasty and kyphoplasty are generally completed on a C-arm machine and DSA (digital radiography), so that the rapid and accurate acquisition of spine segments and the positioning of vertebral pedicles before surgery are very important. Therefore, the puncture point is difficult to position, and repeated fluoroscopy is needed, which not only influences the operation process, but also causes the medical staff and the patient to be exposed to X-ray radiation for many times, and increases the workload of the medical staff.
At present, no universal vertebral body positioner clinically can provide quick and accurate positioning before an operation, and simple self-made positioners such as a multi-purpose Kirschner wire and a clip are used for positioning, and generally only can obtain a normal perspective phase when the positioning is carried out for the first time, so that the accuracy is low, and the positioner is required to be adjusted for many times and the lateral perspective positioning is added in the operation for obtaining more accurate body surface positioning. Therefore, a foldable centrum positive side position positioning device is needed, accurate spinal column segments and pedicle positioning marks can be obtained through positive side perspective when the device is positioned for the first time before an operation, and the positioning time before the operation is shortened.
