Vertebra positioning frame

The utility model discloses a vertebra positioning frame aiming to solve the problems that existing thoracolumbar operations are complicated in positioning steps, and radiation of C-arm X-ray machines on patients and medical staff is large. The vertebra positioning frame comprises a frame body of a rectangular structure. A plurality of first alignment convex strips are arranged on a border of one side of the frame body along the length direction, a fixing strip is connected to the position, close to a border of the other opposite side, of the frame and is parallel to the border provided with the first alignment convex strips, a plurality of second alignment convex strips are arranged on the fixing strip along the length direction, the first alignment convex strips and the second alignment convex strips are in one-to-one correspondence, and the frame body, the first alignment convex strips, the second alignment convex strips and the fixing strips are all made of metal materials. The vertebra positioning frame is adopted for positioning before the thoracolumbar operations, positioning is simplified and facilitated, the C-m X-ray machines can perform single irradiation to realize accurate positioning, operation time is shortened, and radiation injuries to the patients and the medical staff are reduced.
