Embodiment 1
[0045] Such as Figure 1-19 As shown, the spinal orthopedic internal fixation system that can extend itself with the growth of the spine includes a multi-segment telescopic rod 1, a middle pedicle screw set and an end pedicle screw set.
[0046] The multi-segment telescopic rod 1 is formed by alternately connecting fixed-length segments 11 and variable-length segments 12. Both ends of the multi-segment telescopic rod 1 are fixed-length segments 11, and the variable-length segments 12 are The length of the connected fixed-length segment 11 is scalable, and the variable-length segment 12 cannot rotate relative to the fixed-length segment 11 connected at its two ends. Long segment, define the fixed-length segment 11 between the fixed-length segments 11 at the two ends of the multi-segment telescopic rod 1 as the middle fixed-length segment, and each end fixed-length segment is connected with a set of end vertebral segments. Pedicle screw kit, with a set of mid-pedicle screw kits...
