  • Retraction Apparatus And Method Of Use
    Publication number: 20090069635
    Abstract: A retraction apparatus and method are disclosed that provide optimized access to a surgical site. In one form, a retraction frame has a retraction opening with two sets of blades operating therein. The blades are used to sequentially retract the tissue from about an incision. The sequential retraction of the blades generates only narrow gaps between the blades so that tissue and blood encroachment during the surgical procedure are minimized.
