A surgical retractor includes a tubular member having a proximal end and a distal end, a first ring secured at the proximal end of the tubular member and a second ring secured at the distal end of the tubular member. The first ring is formed by combining a first material having a first durometer and a second material having a second durometer. Alternatively, a flexible sealing ring for use with a surgical retractor to prevent cross-contamination during surgery of fluids and solids is presented, the ring composed of at least two materials, the first material having a first durometer and the second material having a second durometer, where the first durometer is greater than the second durometer.
