摘要

A surgical access apparatus includes an access member defining a longitudinal axis and having a longitudinal passageway for reception and passage of a surgical object and an access housing mountable to the access member. The access housing includes a diaphragm mounted thereto. The diaphragm is adapted for rotational movement about the longitudinal axis relative to the access housing. The diaphragm defines at least one internal pocket and has a seal assembly disposed within the internal pocket. The seal assembly has an interface seal member adapted for establishing a fluid tight seal about the surgical object. The seal assembly is adapted for selective movement within the pocket about multiple axes in response to manipulation of the surgical object.
