A wound retractor for retracting a surgical incision includes an inner ring, an outer ring and a distensible sleeve coupled to the inner and outer rings. The outer ring includes at least a pair of circular tubes coupled to each other. At least one of the circular tubes includes a lumen and a split that forms open ends. A noncompliant tubular hoop having a split therein is positioned in the lumen. The tubular hoop is oriented with its open ends positioned away from the split of the circular tubes. A core is positioned in the lumen of the tubular hoop. The core has a first end and a second end and is oriented with the ends positioned away from the split in the tubular hoop. The circular tubes may be parallel or may form a helical pattern similar to a Mobius strip.
