Abstract
In one embodiment, a wound retractor includes a plurality of straps connected between an inner ring and an outer ring assembly. The inner ring is positioned internal of the wound so that it rests against the innermost tissue layer, and the outer ring is located outside of the wound adjacent the outermost tissue layer. The outer ring assembly includes an inner ring having guide holes for the passage of the straps and an outer ring to which the straps are affixed. Rotation of the outer ring of the outer ring assembly relative to the inner ring of the outer ring assembly results in a shorting of the effective length of the straps, retraction of the wound edge and exposure of the wound site.
