The present disclosure relates to a spine connecting rod comprising a rod and a resilient structure. The rod comprises a movable rod, a fixed rod and a cover, and the cover is located between the fixed rod and the movable rod, for fixing the movable rod and the fixed rod. The resilient structure is covered by the rod to provide elasticity in the rod. The spine connecting rod provides excellent fixation on the patient’s spine, and is able to respond to the lateral, anterior or posterior movements of the patient's spine on a range of limited angles. For example, the movements may include flexion or extension. Thus, the spine connecting rod is able to improve patient’s life quality.本發明涉及一種脊椎連桿，包括一桿體和一彈性結構，該桿體包括一活動桿、一固定桿和一檔蓋，該檔蓋位於該固定桿和該活動桿之間，用於固定該活動桿與該固定桿；該彈性結構被該桿體包覆，以提供該桿體之彈性。該脊椎連桿於病患脊椎上實現了良好的固定效果，並且可應對病患脊椎於側向或前後向有限角度之運動，如緩和的彎腰或後仰等動作。因此，該脊椎連桿可提昇病患的生活品質。
