Description
Claims (4)
- 그 하부에 뼈에 삽입되는 나선부를 가지고 그 상부에 U-형상의 채널을 가진 몸체와, 상기 U-형상의 채널에 안착되는 소정길이의 지지바와, 상기 지지바를 U-형상의 채널에 밀착시켜 몸체에 고정하는 고정부재를 구비한 뼈 고정장치에 있어서,상기 나선부의 골지름은 하측으로 갈수록 작아지는 반면 나선부의 산지름은 동일하게 되어 있는 것을 특징으로 하는 뼈 고정장치.
- 제1항에 있어서,상기 채널의 중간에는 상기 지지바에 작용하는 응력을 흡수하는 탄성력을 주는 한편 상기 고정부재에 의한 죔을 용이하게 하는 내부 오목부가 형성되어 있는 것을 특징으로 하는 뼈 고정장치.
- 제1항에 있어서,상기 몸체의 상부 외면에는 링이 외삽되는 리세스부가 형성되되,상기 리세스부는 하측으로 갈수록 외경이 작아지는 테이퍼를 이루고 있는 것을 특징으로 하는 뼈 고정장치.
- 제1항에 있어서,상기 몸체의 상부 외면에는 링이 외삽되되,상기 링은 그 상단부에 내측으로 절곡되어 연장된 플랜지가 형성되고, 이 플랜지의 단부에는 상기 고정부재에 나사결합되는 암나사가 형성되어 있는 것을 특징으로 하는 뼈 고정장치.
