Description
また、前記本体ロックねじは、前記本体メインねじと同一のピッチ及び外径を有し、前記オフセットは、前記本体メインねじのピッチの整数倍の長さを有することを特徴とする。
本発明の他の観点によれば、上述した手術用スクリューと、前記手術用スクリューが装着されるプレートとを含む融合装置を提供する。
下記の各図面の構成要素に参照符号を付するにあたり、同一の構成要素に限っては、たとえ他の図面上に表示されても、できる限り同一の符号を有するようにし、本発明の要旨を無駄に不明確にするおそれがあると判断される公知の機能及び構成についての詳細な説明は省略する。
前記スクリュー本体202の上部には、ドライバなどの器具から回転力の伝達を受けるための本体駆動溝212が形成される。
図5及び図6は、本発明の実施形態による手術用スクリュー200を用いた融合装置220を示す。前記融合装置220は、椎体の間に挿入されるケージ222と、前記ケージ222に形成される貫通孔224に挿入される手術用スクリュー200とを含んでいる。前記手術用スクリュー200は、外表面が曲面であるスリーブボディ214を有するスリーブ204が装着されているため、前記スリーブ204の内部で一定の範囲で回転可能である。前記手術用スクリュー200が、前記ケージ222にセルフロックされながら椎体に螺合されるので、追加のロック装置は必要としないという利点がある。
