Description
(1.技術分野)
技術分野は、皮膚シール(skin seal)およびアンカーカニューレに関し、より詳細には、アンカーカニューレのシャフトの周りで皮膚シールを固定するためのロックアセンブリを有する皮膚シールに関する。
腹腔鏡手順の間、手術器具のためのアクセスポートおよび体腔へのガス注入用(insulfation)ガスを導入するための導管を提供するために、カニューレを利用する。代表的に、鋭いトロカールが、カニューレ内に配置され、そして組織または腹腔壁を穿刺または突き刺すために利用される。その後、トロカールが除去され、カニューレを適所に残し、そしてガス注入用ガス(insufflation gas)が、体腔を押しつけて、解剖学的手術空間を形成する。
カニューレとともに使用するための皮膚シールが提供される。皮膚シールは、一般的に、ロッキングカラーおよびロッキングカラーの遠位端上のフランジを有するフレームならびに該ロッキングカラーと係合可能なラッチアセンブリを備え、その結果、第1位置から第2位置へのラッチアセンブリの移動が、ロッキングカラーの内径を減少し、そしてカラーをカニューレのシャフトに固定する。フランジの遠位端から伸長する可撓性部材が、組織を固定するために提供され、そして漏れを妨げる。
ここで、図1を参照して、バルーンカニューレ12とともに使用する、皮膚シール10の第1の実施形態が、図示される。皮膚シール10は、ガス注入用ガスの漏れを妨げるために、腹腔壁の外側表面に対してシールするために提供される。皮膚シール10がバルーンカニューレ12とともに使用されて図示されるが、本明細書中に開示される皮膚シールの種々の実施形態が、他のスタイルのカニューレとともに使用され得、腹腔壁に対して固定シールを提供し、そしてガス注入用ガスの漏れを妨げることが理解されるべきである。
