An incrementally adjustable wound retractor ( 100 ), 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 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. |
