Description
本開示の本発明の概念は、以下の図面に関連してより詳細に説明される。図面における構造は概略的に示されており、実際の寸法を示すことは意図されていない。
る。それぞれのインプラント80、90の関節面82、92は、除去された自然の足首関節面に置き換わり、自然の関節を模倣する可動域を回復させる。
ベース232に伝達するための平歯車227のグループを含む。平歯車227のグループと、駆動軸222aとの間に、かさ歯車構成225が設けられており、駆動軸222、222aの同軸回転運動を、切断工具ビット受容ベース232の直交向きの回転運動に変換する。
図11Bに示されている。図11Bでは、切削工具受容部分230は、位置合わせピン260の反対側にあるので、開始位置にあることがわかる。位置合わせピン260の機能は、図3~5に関連して以下に説明される。電力ドライバユニット300がその切断モードになると、切削工具ビット500が切削方向に回転すると、切削工具保持部分230が方向T2に並進する。これにより、電力ドライバユニット300全体および電力ドライバアダプタ200を動かすことなく、切削工具ビット500を脛骨の髄内管内へ駆動することができる。電力ドライバユニット300および電力ドライバアダプタ200アセンブリが静止状態に保たれている間、切削工具ビット500は、切削工具ビット受容部分230の並進運動によって自動的に髄内管内へ駆動される。
使用せずに、関節空間22内で位置合わせすることができる。例えば、電力ドライバアダプタ200は、図13A~13Cに示されるもののような位置合わせアーム290で構成することができ、位置合わせアーム290および位置合わせピン292は放射線不透過性である。電力ドライバアダプタ200は、関節空間22に挿入され、透視下で観察されて、切削工具ビット500を位置合わせする。いくつかの実施形態では、電力ドライバアダプタ200は、放射線透過性材料で作ることができ、位置合わせの手がかりのために放射線不透過性マーカー(例えば、標的)を備えることができる。
係合および位置合わせされるとき、位置合わせポスト492が、切削工具ビット500の回転軸線Rに対して平行になるように、構成されている。
脛骨の遠位端、必要であれば、距骨の近位端を切除し、切除された関節空間22を形成することを含み、関節空間は、脛骨の遠位端における脛骨切除面、および距骨の近位端における距骨切除面を含み、関節空間22は、後側で開放している(ステップ4010bを参照)。次に、切削工具ビット500を備えた電力ドライバアダプタ200が、後側から関節空間22内に配置され、切削工具ビット500は、距骨に向けられる(ステップ4020bを参照)。次に、電力ドライバユニット300がオンにされ、切削工具ビット500を駆動して距骨切除面に切り込み、距骨ステムおよび/または距骨インプラント用の増強物を受容するために距骨内に延びる空隙を形成する(ステップ4030bを参照)。
