A tissue retractor comprising an outer ring, an inner ring, and a flexible, metal sheath extending therebetween is described. Embodiments of the outer ring comprise an outer ring rotatable around an annular axis thereof, thereby rolling the sheath therearound when retracting an incision or opening in a body wall. Embodiments of the sheath comprise a plurality of linked loops, a plurality of loops joined by a wire extending through adjacent loops, a braided wire, and a plurality of chains. Also described are kits comprising outer rings, inner rings, and sheaths, some or all of varying dimensions, which may be selected and assembled by the user for their intended use. Some or all of the kit components may be resterilized for reuse.
