Description

【発明の詳細な説明】
【０００１】
【発明の属する技術分野】本発明は膝蓋骨を固定してい
る生体靭帯が損傷又は断裂した場合の人工靭帯を用いて
行う靭帯再建術の際、人工靭帯を膝蓋骨に挿入取り付け
る為の穴を加工する器具に関する。
【０００２】
【従来の技術】膝蓋骨に人工靭帯を挿入するための穴を
明ける専用のドリルガイドはなく、術者が経験と勘によ
って直接ドリルをあて、その位置、深さを決めている。
【０００３】
【発明が解決しようとする課題】骨に穴を明けるという
ことは少なからず患者に侵襲を与える。必要最小限の侵

精度が要求される。術者の経験と勘により穴を明ける
と、位置、深さ、方向性が定まらず、不要な部分まで骨
を削り取る可能性がある。
【０００４】
【課題を解決するための手段】上記の課題を達成するた

め、可動式アーム先端と対象形をしており、可動式アー
ム１は本体２の上部に位置する角穴を通じて平行移動
し、膝蓋骨を挟み込む。膝蓋骨がない状態で挟み込みを
行うと、本体側の角穴が可動式アーム１のＬ字型のカー

ーム１にはストッパー１１が設けてある。又医療用具は
術後の洗浄が大切なので、可動式アーム１の後端にはは
ずしネジ１０が付いており、これを外すことにより可動
式アーム１は本体２より完全に取り外すことができ、本
体角穴の中まで洗浄できる。可動式アーム１、本体２及
びその他の部品の素材としては、医療用具として適性の
高いステンレスＳＵＳ３０４、３１６、４２０、チタン
６−４合金等が適当である。
【０００６】可動式アーム１は底面に連続溝５が施して
あり、これにリリースレバー８の先端の爪６が連続的に
噛み合いロックする。図２に示すように本体内部には板
バネ１３が付いており、膝蓋骨を挟み込む方向に移動す
る場合には自動的に噛み込んでいくが、開く方向に移動
する場合にはリリースレバー８を押し、爪６を連続溝５
から引き離す。
【０００７】可動式アーム１の先端には膝蓋骨前部を固
定するため、爪４ａが付いており、その先端は３つに分
割し、鋭利に加工してある。特に下の部分は長く、皮
膚、筋組織を貫通し膝蓋骨下部に食い込む。本体２の下
部には爪４ｂがついており、この先端は４分割となって
おり、やはり鋭利に加工してある。こちら側は露出した
膝蓋骨に直接押し当てるので、骨の形状に合わせた爪の
長さになっている。この両サイドの爪により膝蓋骨をし
っかりと固定する。
【０００８】膝蓋骨の大きさは患者により異なるので、
明ける穴の深さもそのサイズに合わせる必要がある。図
３に示すように可動式アーム１上部には爪４ａと爪４ｂ
との距離を示す目盛り１２が記してある。これにより、
術者は患者の膝蓋骨の幅を知ることができる。
【０００９】可動式シリンダー３は本体下部に挿入し前
後に移動させ、穴の深さを調節する。可動式シリンダー
３の側面にはその深さを示す目盛り１４が記されてお
り、目盛り１２により得られた数値により深さを決定す
る。可動式シリンダー３の位置は止めネジ１５により固
定する。図４のような決まった位置にストッパーの付い

【００１０】膝蓋骨を挟み込んでいく際、爪４ａ、爪４
ｂの部分を掴むと可動式アーム１が撓み、スライドしに
くくなる。スムーズに挟み込むにはスライド部分に近い
ところに力を加えるべきで、そのためには可動式アーム
１と本体２の上部の水平位置にグリッププレート９ａ、
９ｂ、９ｃを取り付けると効果的である。更にグリップ
プレートの形状を湾曲形にすると指になじみ、挟み込み

【発明の効果】本発明のドリガイドにより、膝蓋骨に人
工靭帯を装着するためのドリル穴を明ける際、術者は位
置、深さ、方向性を容易に確立することができ、患者に
不要な侵襲を加える可能性を大幅に削減できる。
