A surgical retractor liner (12) and integral drape (16) suitable for inserting in an incision and adjusting in place to prevent coross-contamination during surgery between the incised cavity and the surrounding skin of the patient. In one embodiment, a flexible elastic liner (12) impervious to microorganisms has resilient inner (20) and outer rings (18) at either end for holding the liner (12) firmly in the incision. The outer ring (18) is rolled down over itself drawing the liner (12) taut and contiguous in the incision. In another embodiment a skirt (14) is sealingly joined at the outer ring (18) and tapers outwardly and sealingly joins to a drape (16) around a central aperture (16a) therein. The inner ring (20) is inserted and expanded against the inner edge of the incision, and the outer ring (18) is rolled down over the liner (12) and skirt (14) to draw the liner (12) taut in the incision and to retract the sides of the incision while positively anchoring the drape (16) in place around the area of the incision. In another embodiment, a lengthwise incrementally and automatically adjustable wound protector and retractor is provided.
