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.COPYRIGHT KIPO 2013본 발명은 지지부재가 자중에 의해 측방향으로 기울어지는 것을 방지할 수 있도록 된 새로운 구조의 척추 임플란트에 관한 것이다.본 발명에 따른 척추 임플란트는 상기 지지부재(20)의 결합공(21)의 내부에는 상기 헤드부(11)의 상측 둘레부에 밀착되는 상부지지링체(40)와, 상기 헤드부(11)의 하측 둘레면에 밀착되는 하부지지링체(50)가 구비되며, 상기 하부지지링체(50)는 일측이 개구된 링형상의 탄성재질로 구성되어, 고정나사(10)의 헤드부(11) 상하측 둘레면에 상기 상부지지링체(40)와 하부지지링체(50)가 밀착되어 상기 지지부재(20)가 자중에 의해 측방향으로 회동되지 않도록 고정된다.따라서, 척추 임플란트를 시술자가 손으로 지지부재(20)를 잡지 않아도 지지부재(20)가 회동되지 않아서, 지지부재(20)의 고정홈(22)에 로드부재(A)를 삽입하는 것이 매우 용이해지는 장점이 있다.
