Single incision surgical portal apparatus including inner member

摘要

A surgical apparatus includes a housing member and an inner member. The housing member includes an expandable material that is adapted to transition between a compressed condition and an expanded condition. In the expanded condition, an outer surface of the housing member is adapted for a substantial sealing relationship with tissue upon insertion of the housing member within the tissue for accessing an underlying tissue site. The housing member has leading and trailing ends that define a longitudinal axis. The inner member is operably associated with the housing member and includes one or more longitudinal portals extending therethrough adapted for substantially sealed reception of a surgical object. The inner member may be less compliant than the housing member. The inner member may rotate about the longitudinal axis of the housing member.

1. A surgical portal apparatus, comprising:
a housing member comprising an expandable material being adapted to transition the housing member between a compressed condition and an expanded condition in which an outer surface of the housing member is adapted for a substantial sealing relationship with tissue upon insertion of the housing member into the tissue for accessing an underlying tissue site, the housing member defining a longitudinal axis and having leading and trailing ends; and an inner member having a leading end and a trailing end, the leading end of the housing member and the leading end of the inner member being aligned along the longitudinal axis defined by the housing member such that the leading ends of the housing and inner members are coplanar, the inner member including at least one longitudinal port extending therethrough that is adapted for substantially sealed reception of a surgical object, the inner member being less compliant than the housing member, the inner member being rotatable about the longitudinal axis of the housing member relative to the housing member.
