Abstract To provide a surgical access device.SOLUTION: A valve assembly comprises a housing and a seal assembly disposed within the housing. The seal assembly comprises: a septum seal 2160 including an orifice configured to sealingly engage a surgical instrument inserted therethrough, where at least a portion of the septum seal defines a seal curvature; a first guard member 2140 including a plurality of first guard portions 2141 defining slits 2152 therebetween; and a second guard member 2142 including a plurality of curved second guard portions 2141' defining slits 2152' therebetween. The first and second guard members may be positioned in an overlapping relationship with the plurality of first guard portions rotationally offset with respect to the second guard portions. The wide triangular slits of the guard members may improve flexibility of the guard portions.SELECTED DRAWING: Figure 2 【課題】外科用アクセス装置を提供する。【解決手段】弁アセンブリはハウジングとハウジング内に配設されたシールアセンブリとを含み、シールアセンブリは挿入された外科用器具に密封係合するように構成された穴を含むセプタムシール2160であって、セプタムシールの少なくとも一部がシール曲率を画定しているセプタムシールと、間にスリット2152を画定している複数の曲がった第1のガード部2141を含む第1のガード部材2140と、間にスリット2152´を画定している複数の曲がった第2のガード部分2141´を含む第2のガード部材2142と、を含み、第1及び第2のガード部材は第2のガード部分に対して回転オフセットな複数の第1のガード部分と重なり合った関係で配置され、ガード部材の幅の広い三角形のスリットはガード部分の柔軟性を向上させ得る。【選択図】図2
