Abstract

본 발명은 무릎관절을 대체할 수 있는 대퇴골 결합부재에 복수의 곡률부가 형성된 인공슬관절에 관한 것으로, 보다 상세하게는 대퇴골의 경골측 말단에 결합되는 대퇴골 결합부재와, 경골의 대퇴골측 말단에 결합되는 경골 결합부재로 이루어진 인공슬관절에 있어서, 상기 대퇴골 결합부재와 경골 결합부재의 접촉면을 넓혀 어떠한 무릎의 운동에 따를지라도 응력분포를 균일하고 일정하게 분산시킬 수 있도록 하는 대퇴골 결합부재와 경골 결합부재의 응력분산을 위한 인공 슬관절에 관한 것이다. 특히 상기 대퇴골 결합부재와 경골 결합부재의 곡률을 회전에 따른 단계에 따라 구분하여 어떠한 상태에서도 접촉면적을 넓혀 반복되는 하중에 따른 응력을 효과적으로 분산시킬 수 있도록 한다. 상기 경골 결합부재는 대퇴골 결합부재와의 접촉부위에 베어링 부재을 포함하여 상기 베어링 부재의 곡률을 상기 대퇴골 결합부재의 곡률과 대응되도록 형성할 수도 있다. 이를 위하여 본 발명은, 대퇴골의 경골 측 말단에 결합되는 대퇴골 결합부재와, 경골의 상기 대퇴골 측 말단에 결합되는 경골 결합부재와, 상기 대퇴골 결합부재와 상기 경골 결합부재의 사이에 위치하는 베어링 부재를 포함하고, 상기 대퇴골 결합부재는 경골 측 접촉부에 응력분산을 위해 접촉면을 넓게 유지할 수 있도록 다양한 곡률반지름을 갖는 복수의 측면곡률부를 포함하는 것을 특징으로 하는 대퇴골 결합부재에 복수의 곡률부가 형성된 인공 슬관절을 제공한다.
