Abstract
이를 위해 본 발명은 페그가 대퇴골의 하측으로부터 삽입되어 골 시멘트에 의해 대퇴골의 말단에 결합되는 대퇴골 결합부재와, 경골의 상측 말단에 결합되는 경골 결합부재와, 상기 경골 결합부재와 대퇴골 결합부재 사이에 설치되는 연골 플레이트로 구성된 인공 슬관절에 있어서, 상기 대퇴골 결합부재의 페그는 외측 둘레를 따라서 다수의 결합홈이 길이방향으로 길게 형성되고, 상기 결합홈은 폭방향의 내측을 향해 오목하게 라운드진 라운드부가 형성된다.
Description
도3은 본 발명에 의한 인공 슬관절의 대퇴골 결합부재의 구조를 보인 도.
도4는 도3의 측면 구조도.
도5는 대퇴골 결합부재에 슬개골 보호부재가 접촉된 상태를 보인 도.
도6은 슬개골 보호부재의 측면도.
도7은 슬개골 보호부재가 슬개골에 결합된 상태를 보인 도.
또한, 상기 삽입부(420)의 길이방향으로 걸림홈(421)의 양측으로는 외측둘레를 따라서 외측으로 돌출된 걸림돌기(422)가 더 형성되어 있게 된다.
또한 걸림돌기(422)에 의해서도 견고하게 고정이 되는데, 걸림돌기(422)의 외측부위는 상기 걸림홈(421)과 반대방향으로 라운드가 형성되고, 걸림돌기(422)의 라운드진 부위의 양측과 걸림홈(421)의 라운드진 부위가 연이어 'S'형태로 형성됨으로써 모서리진 부위가 없어 골 시멘트(600)가 빈틈없이 채워지게 되므로 더욱 견고한 고정이 가능하게 되는 것이다.
