Abstract
A surgical retractor of the type used to retract tissue or muscles during a surgical operation. A retractor (20) comprises an outer ring (24) having a downwardly extending outer arcuate blade (24a) and an inner ring (22) having a downwardly extending inner arcuate blade (22a). The inner ring is nested within the outer ring such that the inner arcuate blade is rotatable from a first position overlapped to the outer arcuate blade, to a second position in which it is diametrically opposite the outer blade. A first handle (26) is used to hold the outer ring while a second handle (28) rotates the inner ring. The surgical retractor is inserted into an incision with the arcuate blades in the first position and the outer and inner rings are rotated to spread muscle and tissue.
