Various embodiments of the present invention provide a surgical retractor having two blade-supporting arms, which are mounted to be laterally slideable towards and apart from each other by a toothed rack. Each arm supports a respective retractor blade. In some embodiments, the retractor blades are curved in the same direction as each other so that the first blade is concave in the first direction, and a second blade is also concave in the same direction. Alternatively or additionally, in some embodiments, a cushioned material or cushioned sleeve is present on the blades where the blades contact the anatomy. The cushioned material or sleeve may be made of a soft silicone. Further, the cushioned material or sleeve may be coated or molded onto the blade structure, or may be a removable sleeve that is manually slid onto or off of the blade structure. Also, alternatively or in addition in some embodiments, blade-mounted lighting may be provided. |
