Abstract
【解決手段】それぞれ体壁の外表面と内表面に近接して配置されるように適合された第1と第2の保持部材55,65とを含む。2つの保持部材の間に伸びる薄膜75は、切開部を貫通して伸びるように適合された咽喉部を形成し、第1の保持部材か55ら咽喉部へと伸びる第1の漏斗状部と、第2の保持部材65から咽喉部へと伸びる第2の漏斗状部とを形成する。薄膜の咽喉部は、器具が存在する時には、器具密閉を形成し、器具が存在しない時には、ゼロ密閉を形成するような特性を有する。第1の保持部材75は、固定された又は可変的な直径を有するリング66を含むことができる。リング66は、それぞれ2つの端部を有する第1と第2の部分76,86で形成されることができる。

Description
本出願は、2000年10月19日付米国特許仮出願第60/241,953号「Hand−Assisted Laparoscopy Apparatus and Method」、並びに2001年9月21日付PCT出願番号PCT/US01/29682号「Surgical Access Apparatus and Method」に優先権を主張する非仮出願であり、これら両出願は、引用により本明細書に組み込まれる。
腹腔鏡法又は閉鎖式外科手術法は、開放式開腹術にまつわる問題の多くを排除する。典型的な加圧腹腔鏡法においては、腹壁に穴が開けられて、少なくとも1つのトロカールが腹膜内に挿入される。腹腔内にガスが導入されて、腹壁を内臓から持ち上げる。その結果、大きな、遮るものがない手術領域が得られる。様々な施術の必要に応じて、追加的なトロカールを挿入することができる。外科手術部位の視認性を提供するために、腹腔鏡が使用される。近年、腹腔鏡法のための器具が数多く開発されてきており、外科医は、外科手術の様々な局面に対して快適な「遠隔操作」方法が可能になった。切開、解剖、焼灼、ステープル留め(stapling)、及び縫合の全てが、腹腔鏡装置の製造業者により対処されてきた。
本発明の上記及び他の特徴及び利点は、関連する図面を参照しながら、好ましい実施形態の以下の説明から一層明らかになるであろう。
