Description
本発明は、手術用開創器および外科手術中に身体の既定領域を保定させるための装置に関し、より詳細には、好ましくは冠動脈バイパス移植手術で使用される改良セグメントアームアセンブリと関連して使用される手術用開創器および保定装置に関し、さらに、より具体的には、種々の外科手術で使用される種々の手術用開創器および保定装置と併用されるセグメントアームに関する。
心臓血管系疾患は年間数百万人が罹患する疾患であり、米国および世界中で多くの人の死因となっている。特に多くみられる心臓血管疾患の形態としては、心臓に向かう血流に影響を与えるような、アテローム性動脈硬化症(冠動脈疾患)または心臓血管系内の重要箇所で血流の阻害を引き起こすその他の症状に起因する、心臓への血液供給の減少がある。
本発明は、身体の既定領域の引き寄せ、保定、または操作のためのシステムを特徴とする。該システムは、手術用開創器と併用するためのそり状アセンブリ、保定用のアームシステムまたは器具、および組織の支持または保定用の装置、ならびにそれらに関連する使用方法を含む。本発明はさらに、例えば横隔膜用開創器、弁用開創器、外科手技中に使用する光源または吸引装置など、多数の手術用器具のうち任意の器具を支持するシステムも特徴とする。
患者の心臓を保定するためのシステムは、種々の縫合技術または手技に特に有用である。この種の手技のひとつの例として、心臓手術中のバイパス移植片の吻合がある。この種の手技において、術者は、周長が約1mmである血管の周囲を、心臓表面の動いている血管に縫合することを試みる。本発明の別の利用領域としては、悲惨な結果を回避するためにアクセスおよび保定が極めて重要であるか、または、正確に規定された術野を確保することが所望される、脳手術、心臓弁手術、または他の血管手術がある。当業者には、本発明が、心臓手術に特に適しているものの、既定領域の組織の保定、引き寄せ、または隔離が所望される身体上または身体内の任意の位置で使用可能であることが理解されるものと思われる。これには、肝臓、腎臓、膀胱、胃、腸、脳および脈管ならびに他の軟部組織の手術が含まれるが、これらに限定されることはない。さらに、後述するように、当業者には、術中に任意の手術用器具または装置が自立式となるように、システムの支持部品を適合させてもよいことが理解されるものと思われる。
Claims (10)
- 患者の外科手技に使用されるシステムであって:
複数の開創器アームと該開創器アームに連結する部分とを有する開創器であって、該開創器アームが互いに対して可動である開創器;
該開創器に対して作動可能な状態で配置可能な保定アームであって、医療手技中に所望の位置に医療器具を保持するようなサイズである保定アーム;
該保定アーム上に作動可能な状態で配置された保定装置;
選択的に該開創器上に装着可能であり、且つ、該保定アームに対して回転可能であるコネクター;および
該保定アームに設けられたノブアセンブリであって、該開創器および該保定装置から離して配置され、且つ、該保定アームに対する該保定装置の位置決定を制御するために調節可能であるノブアセンブリ、
を含み、
前記ノブアセンブリは、一対のシャフト部分の隣接する端部に取り付けられ、これらのシャフト部分を相互に接続し、且つそれらの相対移動を可能にすることを特徴とするシステム。 - ノブアセンブリが、開創器および保定装置に対する保定アームの位置決定を制御するために調節可能である、請求項1記載のシステム。
- 保定アームが、遠位シャフト部分を及び近位シャフト部分を含み、これらのシャフト部分が互いに対して可動である、請求項1記載のシステム。
- 保定アームが遠位端部分と近位端部分とを含み、且つ、該遠位端部分が、取り外し可能な状態で装着された保定装置を含む、請求項1記載のシステム。
- 保定アームが複数のコネクターを含み、且つ、該コネクターがノブアセンブリ部品の動きに対応して可動である、請求項4記載のシステム。
- 保定アームがノブアセンブリ部品を含み、且つ、該ノブ部品の作動が該保定アームの遠位端部分の保定装置の動きに影響を及ぼす、請求項4記載のシステム。
- ノブアセンブリの動きによって、第一のロッド部品が遠位方向および近位方向へ移動し、且つ、選択的に該第一のロッド部品がその遠位方向および近位方向のうちいずれか一方への移動によって保定装置の一部分に嵌合する、請求項1記載のシステム。
- 保定装置を保定アームに対して嵌合および離脱させるためロッド部品が嵌合ポジションと離脱ポジションとの間を移動可能である、請求項7記載のシステム。
- ロッド部品が、嵌合ポジションにおいては保定アームの遠位端部分に配置されたスロット部品内に延出し、且つ、離脱ポジションにおいてはスロット部品から離れた位置に配置される、請求項7記載のシステム。
- ノブアセンブリの動きによって、第二のロッド部品が遠位方向および近位方向へ移動し、且つ、選択的に該第二のロッド部品が嵌合ポジションと離脱ポジションとの間で保定アームの一部分を通過する、請求項1記載のシステム。
