HOLLOW MULTI-LUMEN ACCESS PORT
A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity includes a seal anchor member that is adapted and configured to be placed within an incision of a tissue in a substantially sealed relation. The seal anchor member includes a hollow body portion and may also include a removable cap including a plurality of lumens that are each adapted and configured to receive a surgical instrument therein.
1 . A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises:
a seal anchor member having a longitudinal axis, the seal anchor member including a compressible body portion having an inner surface defining a lumen along a longitudinal axis of the seal anchor member, the lumen defining a first diameter and having ribbing along the inner surface.
2 . The surgical apparatus of claim 1 , wherein the ribbing increases the structural rigidity of the flexible body portion.
3 . The surgical apparatus of claim 1 , wherein the ribbing resists compression when placed within the incision.
4 . The surgical apparatus of claim 1 , wherein the ribbing extends longitudinally along the inner surface.
5 . The surgical apparatus of claim 4 , wherein the ribbing extends from the proximal end of the compressible body portion to the distal end of the compressible body portion.
6 . The surgical apparatus of claim 1 , further comprising a cap that is releasably securable to a proximal end of the seal anchor member.
7 . The surgical apparatus of claim 6 , wherein the cap includes one or more openings extending along the longitudinal axis, each opening defining a diameter, each diameter being less than the first diameter of the lumen of the seal anchor member.
8 . The surgical apparatus of claim 6 , wherein each opening of the cap is sized to receive a surgical object.
9 . A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises a body portion having an inner surface defining a lumen along a longitudinal axis of the seal anchor member, the body portion being selectively compressible so as to be inserted within a tissue tract, the lumen having ribbing along the inner surface, the ribbing increasing the structural rigidity of the flexible body portion such that, after the body portion has already been positioned within the incision, the ribbing helps maintain the lumen open by resisting compression forces exerted on the body portion by the tissue tract.
10 . The surgical apparatus of claim 9 , wherein the ribbing extends longitudinally along the inner surface.
11 . The surgical apparatus of claim 10 , wherein the ribbing extends from the proximal end of the compressible body portion to the distal end of the compressible body portion.
