PROBLEM TO BE SOLVED: To provide a surgical access apparatus to be releasably and reliably fixed within the tissue of a patient during a period when a low-invasive treatment is continuously performed.SOLUTION: The surgical access apparatus for positioning within an incision in tissue includes an elongated seal member and a deployment member. The elongated seal member includes a longitudinal passageway for the reception and passage of a surgical object, is adapted to transition between first and second conditions, is composed of an at least semi-resilient material such that the elongated seal member is normally biased towards the first condition thereof. The deployment member is the one whose distal longitudinal movement along the longitudinal axis causes the elongated seal member to transition from the first condition to the second condition, which may be detached from the elongated seal member in a state where the elongated seal member is in the first condition, thereby leaving the elongated seal member within the incision to receive the surgical object.COPYRIGHT: (C)2010,JPO&INPIT【課題】低侵襲性処置の継続の間中、患者の組織内に解放可能に、かつ確実に固定され得る外科用アクセス装置を提供すること。【解決手段】組織の切開部内に位置決めするための外科用アクセス装置であって、細長いシール部材であって、外科用物体を受け入れて、これを通すための長手方向の通路を有し、第1の状態と、第2の状態との間を移行するように適合され、少なくとも半弾性材料を含み、その第1の状態に向かって通常は付勢されている、細長いシール部材と、配備用部材であって、該長手方向軸に沿った該配備用部材の遠位長手方向の動きが、該細長いシール部材を該第1の状態から該第2の状態へ移行させ、該配備用部材は、該細長いシール部材が該第1の状態にある状態で、該細長いシール部材から引き離され、それによって、該外科用物体を受け入れるために、該細長いシール部材を該切開部内に残す、配備用部材とを備えている、外科用アクセス装置。【選択図】図1
