Title
(JA) 膝関節置換術の際に大腿骨及び脛骨に対する切削を案内するためのガイド組立体
Abstract
(JA)

大腿骨及び脛骨の膝コンポーネントの取り付けに備えて、膝関節の大腿骨及び脛骨の切削を案内するための組立体である。例えば、組立体は、屈曲角の範囲内で切削の位置決めをする間、脛骨及び大腿骨の伸延の調節を制御することを可能にするトルク・ボルトを通して接続される、脛骨及び大腿骨のIMロッドを含むことができる。また、組立体は、脛骨及び大腿骨のIMロッドに取り付ける比較的狭くて薄型のコンポーネントを手段とする、膝関節への比較的小さくて非侵襲性のアプローチによって有用である。更に、組立体は、外科手術の現場において迅速な組み立て及び分解を可能にするために、幾つかの簡易脱着コンポーネントを含む。これらの態様のそれぞれは、脛骨及び大腿骨に対する最初の基準切削を正確に案内するための組立体の能力と共に、患者のために成果の向上を促す。
