PURPOSE: A spinal implant is provided to facilitate inserting a rod member into a fixing groove of a supporting member as the supporting member does not circulate even when a practitioner does not hold the supporting member with hands. CONSTITUTION: A spinal implant comprises a rod member (A) formed in a rod shape and a spinal fixing member (B) that is coupled to the rod member at a predetermined interval and to a spinal cord. The spinal fixing member comprises a fixing screw (10) that is fixed to a spinal cord, a supporting member (20) included in an upper end of the fixing screw, and a nut member (30) coupled to the supporting member. A head unit (11) at an upper end of the fixing screw is rotatably coupled to the supporting member, and a binding hole (21), to which the nut member is screw-coupled, and a fixing groove (22), which is formed in an alternating manner with the binding hole and to which the rod member is inserted. A lower part of an inner peripheral surface of the binding hole is adhered to an upper side girth unit of the head unit, and an outer peripheral surface is a cylindrical shape having a cross-section of a rectangular shape in correspondence with the inner peripheral surface of the binding hole, wherein an upper part supporting ring body (40) that is distanced apart from the inner peripheral surface of the binding hole and a lower part supporting ring body (50) that is adhered to a lower side girth surface of the head unit are included. |
