An incrementally adjustable wound retractor (199), having a first ring (102) with a diameter greater than the desired diameter of the wound incision. A second ring (104), having an annular axis and a diameter greater than the desired diameter of the wound incision. A flexible sleeve (106), disposed in a generally cylindrical form between the first and the second rings (102, 104), the second ring may be rolled over itself and around the annular axis to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter. |
