Abstract
앙카체결부재에 구비된 앙카결합부에 앙카를 고정체결하면 앙카에 형성된 호형홈과 앙카결합부에 형성된 호형홈이 일치되면서 앙카결합부 내부 관통홀과 일직선으로 일치되는 봉합사삽입공이 자연스럽게 형성되도록 하여 봉합사 결합에 대한 선택의 폭이 넓고 봉합사의 결합이 매우 용이하며,
수술시 앙카의 선단부 양측으로 돌출된 앙카결합부의 갈라진 양측선단부가 뼈조직을 천공하면서 앙카를 나사체결할 수 있는 것이어서, 앙카의 체결이 매우 간편하고 신속하게 이루어지는 것은 물론 특히, 돌출선단부가 후방에서 전방으로 약간 뾰족한 형태이고 전방면에서 보면 각형외면부가 " > "와 같은 형태로 형성되어 있기때문에 뼈조직의 천공이 용이할 뿐 만 아니라 회전에 대한 마찰저항의 감소로 뼈조직에 무리한 힘이 가해지지않고 부드럽게 압입되므로 뼈조직의 손상이 해소됨과 동시에 무리한 힘이 가해지지 않으므로 해서 양측 돌출선단부가 깨지는 등의 파손 발생의 염려가 없어 안전하며,
앙카의 외면 후방부에 전방부보다 나선간격이 좁은 나선밀집부위를 형성하여 나선밀집부위에 의한 고정결속력의 증대로 뼈조직에 앙카가 헐겁지 않고 견실하게 나사 결합되어져 봉합사를 잡아당겨 근육이나 인대를 뼈에 붙이는 작업을 안전하게 할 수 있도록 이루어짐에 그 특징이 있는 것이다.
