Abstract
Description
本開示は、密封装置を含む可撓性外部カニューレシースに関する。より具体的には、本開示は、カニューレを通る器具の挿入時にカニューレシース管腔を密封する密封部材を含む、腹腔鏡手術で使用するためのカニューレシースに関する。
外科手術であって、その最中に内部手術部位にアクセスするために、身体組織の小さな開口部に手術器具を通過させる外科手術が開発されてきた。一般的に内視鏡手術と呼ばれるこれらの外科手術は、幅広く受け入れられるようになってきた。本明細書で使用されるような内視鏡という用語は、腹腔鏡および関節鏡視下手術を含む、あらゆる種類の低侵襲外科手術を含むように定義される。典型的には、これらの手術中に、切開が身体組織に形成された後、管腔を画定するカニューレまたはカニューレシースが切開を通して挿入され、手術部位に関して固定的に配置される。いくつかのそのような手術中に、患者の体内に作業域を生成し、体腔内の深部臓器を損傷する危険性を伴わずに、トロカールが体腔を穿刺することを可能にするように体腔が吹送ガスで膨張させられる。概して、カニューレは、体腔内への手術器具の挿入の前および後に、カニューレ管腔を密封して体腔内の吹送ガスが漏出することを防止するために、1つまたは複数の密封部材を含む。1つまたは複数の密封部材はしばしば、異なるサイズおよび形状の複数の器具の周りを密封可能である、調節可能な密封要素を含む。
