Abstract
상기와 같은 구성의 본 발명은, 상체와 하체 사이의 축 이동을 허용하여 즉, 관절체의 이동을 허용하여 인공 디스크 보형재의 거동 자유도를 향상시킨 효과가 있다. 그리고, 상체와 하체에는 걸림부가 돌출되어 척추골에 더 견고히 고정될 수 있는 효과가 있다.
Description

Claims (5)
- 이웃하는 척추골들 사이에서 삽입되는 인공 디스크 보형재에 있어서,
일측의 척추골에 고정되며 고정돌기가 돌출된 하체;와
일측면은 볼록면으로 형성된되고 타측면에는 상기 고정돌기가 삽입되는 장착홈이 형성된 관절체; 및
타측의 척추골에 고정되며 관절체의 볼록면에 밀착되어 활주 가능하도록 오목면이 형성된 상체;를 포함하며,
상기 고정돌기의 끝단에는 외경이 확장된 플랜지가 형성되고 상기 플랜지의 외경 보다 더 작은 내경을 갖는 림이 장착홈의 둘레를 따라 돌출 형성되며 상기 관절체는 탄성을 갖는 재질로 제조되는 것을 특징으로 하는 인공 디스크 보형재.
- 제 1 항에 있어서, 상기 플랜지의 진입 시, 림의 탄성 변형을 촉진하도록 상기 림에는 절개부가 형성된 것을 특징으로 하는 인공 디스크 보형재.
- 제 2 항에 있어서, 상기 관절체는 폴리에틸렌(Poly Ethylene) 또는 폴리에테르에테르케톤(PolyEther Ether Ketone) 중 어느 하나를 포함하는 재질로 제조되는 것을 특징으로 하는 인공 디스크 보형재.
- 제 1 항 내지 제 3 항 중 어느 한 항에 있어서, 상기 관절체가 하체에서 고정돌기를 중심으로 일정 간격만큼 이동가능하도록 상기 림의 내경은 고정돌기의 외경보다 더 크게 형성된 것을 특징으로 하는 인공 디스크 보형재.
- 제 4 항에 있어서, 상기 하체와 상체는 척추골과 맞닿는 표면에 각각 걸림부가 돌출형성된 것을 특징으로 하는 인공 디스크 보형재.
