Description
図8および図9に、遠位チップアセンブリ18を、さらに詳細に示す。ある実施態様では、複合チップ18は、約10cm(4インチ)〜約15cm(6インチ)の長さを持つ(全ての値とその間の部分範囲を含む)。ある実施態様では、複合チップ18は約5(2インチ)〜約30cm(12インチ)の長さを持つ(全ての値とその間の部分範囲を含む)。変更態様では、必要に応じて、または希望により、他の適切な長さを有効に利用することができる。
本発明の実施態様は、骨および/または組織精密除去用の往復切削ブレードを提供する。ある実施態様では、往復切削ブレードの5つの面を遮蔽または被覆または防護して、遮蔽外科用やすりを提供する。
ある実施態様によれば、外科用ヤスリ器具12は、既存の焼灼機器60への接続に対応することにより、切削または彫刻したばかりの骨または他の組織の少量の出血を停止させることができる。この実施態様において、システムが持つ特別な特徴は、導電性金属やすりブレード106を覆っている非導電性遮蔽材108である。
図22に、光ファイバープローブ124および126を含む光ファイバー視覚システム218を示す。一部の外科的実施態様では、光ファイバー視覚システム218により、外科医は、神経根圧迫と正常な身体機能に対する損傷とを引き起こしている不要な骨および軟骨沈着の存在を視覚的に見て、確認することが可能になる。不要な物質に関するこの情報は、視覚画像をコンピュータデータベースに保存し、参照および記録のために直ちにカラー画像を印刷することによって文書化し記録することができる。
トロイダルトランスミッションシステムまたはトロイダル動力変換システム98は、回転運動または回転動作を往復運動または往復動作に変換する機械的変換装置である。動力付きハンドピース20は、組織除去器具または組織除去ブレード106の切削動作に動力を供給するための回転原動機80を格納する。原動機80の回転機械動作は適切な往復ストローク長を持つ往復機械動作に変換される。機械的動作変換装置は単純であって部品数が少ないことが望しい。
拍動流水ポンプシステム290を使い捨て切削ブレードアセンブリ18に組込み、遠位カバー72内に格納する。拍動水ポンプ290は患者の体内に滅菌水を供給し、ある実施態様では、「患者間での」生物学的汚染が起こらないことを保証するために、1回使用後に処分される。本発明の実施態様の拍動流水ポンプシステムは、流体輸送が望まれる数多くの分野および用途に役立つ。ある実施態様では、各直線運動ストローク後に水のパルスがもたらされる。
図39は、カバーまたはハウジング74と、ビデオカメラ78と、原動機アセンブリ80と、遠位チップアセンブリ18のインターフェース部材102および継手104に連結するための遠位インターフェース部材322とを含む、動力付きハンドピース20を示す。インターフェース部材322は、インターフェース開口部158と実質的に揃うように調整された開口部324を持ち、ここに光ファイバープローブ124、126を通してカメラ78と接続することができる。
本明細書で説明し例示する方法は、記載した行為の順序に限定されず、また記載した行為を必ずしも全て実施するとも限らない。本発明の実施態様の実施においては、他の行為順序、または全ての行為のうちの一部だけ、または行為の同時進行も、利用することができる。
図43〜43は、整形外科用遮蔽往復運動外科用やすり器具または機械12aのさまざまな図である。外科用やすり器具12aは、一般に、ハンドピース20aにドッキングされてそこから動力を供給される遠位チップアセンブリ18aを備える。
