Description
トロカールは、体腔に穿刺するのに使用する短い尖った器具である。体から液体を排出するために、トロカールによって形成された開口にカニューレが挿入されるであろう。トロカールは内視鏡検査にも使用することができる。トロカール組立体は米国特許第4,601,710号および4,654,030に開示されている。
別の構成例では、フランジは、患者の体の切開部を取り囲む取付けリングと係合している。
或いは、当該入口シール手段は、スリーブ入口内の第1取付具と、第2の取付具と、これらの取付具の間に延在する可撓性材料からなるシール本体とを有し、取付具の一方を他方に対して捩じり、捩じられたシール本体を通過する腕と係合させる。
他の構成例では、第1取付具がスリーブ内においてスリーブの入口に取付けられたリングを有する。
本発明の一実施例では、入口シール手段は、入口に設けられた第1シール要素と、外科手術用手袋に設けられた第2シール要素とを有し、これらのシール要素が相互に係合して、入口を通して手袋が通過するときにスリーブをシールする。
好ましくは、リングは軸方向に対向する一対のリング部品を含み、可撓性のシールスリーブの対向する自由端が各リング部品に取付けられており、捩じりシール形状にするためにリング部品の一方が他方のリング部品に対して回転され、シール形状が作られた状態でリング部品の一方が他方のリング部品に対して固定される。
外科医の腕および/または器具のための二以上の入口開口をスリーブに設けてもよい。
また、例えば、スリーブに沿って離間された2個の入口シールカフを設けることにより、中間加圧環境を作り出してもよい。カフの内側は外側カフによって提供されるシールが開かれる前はシールされている。
弁101は、本例では一対の軸方向に対向するリング部品105、106と、可撓性材料から成るシールスリーブ107とを含む外側リングを備えており、シールスリーブ107の自由端107a、107bは各リング部品105、106に取り付けられている。
