    • PROBLEM TO BE SOLVED: To provide a seal assembly that establishes sealing engagement with a plurality of differently dimensioned instruments passing through a trocar.SOLUTION: A seal assembly 30 comprises: a caged seal assembly 32 having two seal segments formed of an elastic material; and an auxiliary seal assembly 34 having an annularly shaped main body 39 formed of an elastic material. The caged seal assembly 32 and the auxiliary seal assembly 34 are configured in series and oriented to receive an elongated instrument through a first center opening in a center section of the annularly shaped main body 39 and a second center opening in a center section of a circularly shaped body formed of the two seal segments. In this configuration, the caged seal assembly 32 having the circularly shaped body formed of the two seal segments and the auxiliary seal assembly 34 having the annularly shaped main body 39 are movably disposed in the seal assembly 30 and the first center opening has a larger diameter than the second center opening.
    • 要解决的问题:提供一种密封组件,其与穿过套管针的多个不同尺寸的器具建立密封接合。解决方案:密封组件30包括:笼式密封组件32,其具有由弹性材料形成的两个密封段; 以及具有由弹性材料形成的环形主体39的辅助密封组件34。 笼式密封组件32和辅助密封组件34被构造成串联并且定向成通过环形主体39的中心部分中的第一中心开口和循环中心部分的中心部分中的第二中心开口 由两个密封段形成。 在这种构造中,具有由两个密封段形成的圆形主体和具有环形主体39的辅助密封组件34的笼形密封组件32可移动地设置在密封组件30中,并且第一中心开口具有较大的直径 比第二中心开口。
