摘要
An automatic-extending and anti-rotation scoliosis correcting system comprises a pedicle screw (1) and a plurality of correcting rods (2) locked with the pedicle screw (1). Each correcting rod (2) includes a sleeve (2.1) and an insertion rod (2.2) which can be inserted into the sleeve (2.1). The inner wall of the sleeve (2.1) and the insertion rod (2.2) are the same in shape and are in clearance fit. A positioning mechanism for limiting the relative rotation of the insertion rod (2.2) with respect to the sleeve (2.1) is arranged on the matching surface between the insertion rod (2.2) and the sleeve (2.1). The scoliosis correcting system has the benefits of ensuring the side stability and the anti-rotation function for scoliosis correcting; having the performance of automatic extending along the growth direction of the spine; and ensuring both the short-term operating effect and the long-term curative effect.
