Single incision surgical portal apparatus including inner member
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 having a leading end and a trailing end and defining a longitudinal axis between the leading and trailing ends; and
an inner member positioned within the housing member and rotatable relative to the housing member about the longitudinal axis of the housing member, at least one port extending longitudinally through the inner member, the 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 aligned along the longitudinal axis of the housing member such that the leading end of the housing member and the leading end of the inner member are coplanar.
2. The surgical portal apparatus according to claim 1 , wherein the housing member is formed of a material configured to transition between a compressed condition and an expanded condition.
3. The surgical portal apparatus according to claim 1 , wherein the inner member is formed of a first material and the housing member is formed of a second material, the first material being less compliant than the second material.
4. The surgical portal apparatus according to claim 1 , wherein the housing member defines a passage that extends longitudinally through the housing member, the inner member being removably received in the passage of the housing member.
5. The surgical portal apparatus according to claim 1 , wherein the at least one port includes a first port and a second port, the first port having a diameter different from a diameter of the second port.
6. The surgical portal apparatus according to claim 1 , wherein the inner member is cylindrical.
7. The surgical portal apparatus according to claim 1 , wherein at least one of the inner member or the housing member is fabricated from an elastomeric material.
8. The surgical portal apparatus according to claim 1 , wherein the housing member has an hour-glass shape.
9. The surgical portal apparatus according to claim 1 , wherein the housing member is fabricated from at least one of:
a foam; or
a gel.
10. The surgical portal apparatus according to claim 1 , wherein the housing member has an outer surface configured to secure to tissue while positioned in an opening formed within tissue.
11. The surgical portal apparatus according to claim 1 , wherein the trailing end of the housing member and the trailing end of the inner member are aligned along the longitudinal axis of the housing member such that the trailing end of the housing member and the trailing end of the inner member are coplanar.
12. The surgical portal apparatus according to claim 1 , wherein the inner member is solid.
