Claims (4)
- 대퇴부 골절시 내척수용 네일과 래그나사를 이용하여 고정 시술함에 있어서,
상기 래그나사는;
나사부와, 몸체부 그리고 체결부로 각각 분리된 구조로 되어 상기 몸체부의 앞쪽에 나사부가 삽입되고, 상기 체결부는 몸체부 내부로 삽입되어 상기 나사부의 후단과 나사맞춤되어 상기 나사부와 몸체부가 일체로 형성되도록 구성되며, 골절부위에 시술 후, 나사부는 골에 유착된 상태로 유지되고, 상기 체결부를 나사부로부터 이탈시켜 몸체부와 내척수용 네일을 쉽게 제거할 수 있도록 한 것을 특징으로 하는 분리구조를 가지는 뼈 고정용 래그나사. - 제1 항에 있어서,
상기 몸체부는;
선단이 개구되어 나사부의 일부가 삽입되는 삽입고정부; 및
상기 삽입고정부와 연장형성되며 나사부의 수납 위치를 정하기 위한 고정부; 및
상기 고정부의 중앙에 상기 체결부가 통과하기 위한 관통구;를 포함한 것을 특징으로 하는 분리구조를 가지는 뼈 고정용 래그나사. - 제1 항에 있어서,
상기 나사부는;
선단에 수나사가 형성되어 골수에 나사고정되고, 후단에는 체결부가 나사맞춤되기 위한 암나사가 형성되며, 상기 몸체부의 삽입고정부의 지름보다 동일하거나 작게형성된 것을 특징으로 하는 분리구조를 가지는 뼈 고정용 래그나사. - 제1 항에 있어서,
상기 체결부는;
선단에 상기 나사부의 후단에 형성된 암나사와 체결되기 위한 수나사가 형성되고, 후단에는 드라이버에 의해 조립 또는 해체할 수 있는 체결홈이 형성된 것을 특징으로 하는 분리구조를 가지는 뼈 고정용 래그나사.
