Abstract
【解決手段】 外科アクセス装置は、弁ハウジングと、孔を有して弁ハウジングに設けられ、広い範囲の直径を有する器具を受入れて差し向けるための器具受入れ要素とを有している。器具受入れ要素は概ね砂時計のように成形されたブレードまたはメッシュ管を有している。外科アクセス装置は、ゲル材料から成型されたアクセス隔膜シールを有してもよい。外科アクセス装置は、約3.5mmから約12.9mmまでに及ぶ直径を有する器具に撓み可能に係合することができる。
Description
代表的な腹部腹腔鏡外科手術においては、腹部に吹き込みを行なって外科手順を行なうべき空洞を加圧し、それによりこの空洞を拡大する。以前には、この手順に使用される種々の器具をトロカールの作用チャンネルに、一度に1つ、挿通して外科手術を行なっている。器具がトロカールに挿通されるときに吹き込み圧力を維持するために、器具のまわりにシールを形成するように弁がハウジングに設けられていた。これらの器具弁は、代表的には、隔膜弁の形態で設けられていた。器具を取出すときには、代表的には、吹き込み圧力を維持するためにゼロ閉鎖弁がトロカールを密封するように設けられていた。米国特許第6,162,196号(これは参照によりここに組み入れられる)に開示されている二重ダックビル弁のようなゼロ閉鎖弁が使用されてもよい。
当業者によれば、本発明の精神および範囲を逸脱することなしに、多くの変形例および変更例を行い得る。従って、図示の実施形態を例の目的でのみで述べたこと、および本発明を限定するものと解釈すべきでないことは、理解しなければならない。
