The present invention discloses an intra-vertebral stent structure comprising a stent body and a screw rod. The bracket body has a screw shaft center, and a deformation sleeve is sleeved on the screw shaft. The deformation sleeve can be displaced by the end nut to rotate, and the deformation sleeve is deformed to expand outward； the screw rod can be The nut is placed on the body of the bracket and rotated to rotate it forward. Thereby, the purpose of helping the spinal fracture reduction and increasing the compressive strength and stability of the spine is achieved.本創作揭露一種脊椎內支架結構，包含支架本體及螺合棒所構成。該支架本體具有一螺桿軸心，螺桿軸心上套置一變形套筒，該變形套筒可受末端的螺帽旋動而位移，使變形套筒變形而向外擴張；該螺合棒可套置於支架本體之螺帽，並藉以旋轉而令其向前螺動者。藉此，達到幫助脊椎骨折復位，增加脊椎抗壓強度及穩定度之目的。
