Abstract
The present invention discloses an endoscopic retractor for use in minimal invasive surgery. A retractor blade is pivotally attached to an elongated hollow cylinder. An elongated shaft slides and rotates within the cylinder. At one end of the shaft is a handle. The other end includes a locking surface which bears against the blade. The blade can be positioned for movement of the retractor through a cannula, then moved into a closed position for use during the procedure.
