Abstract

A surgical retractor assembly that utilizes a tubular shaft and a connection nub. A pivot joint connects one end of the tubular shaft to the connection nub. The pivot joint enables the connection nub to move relative the tubular shaft along a path that is coplanar to the axis of the tubular shaft. Together, the tubular shaft and the connection nub create an elongated element that can be introduced into a small incision. A retractor blade is provided. A bearing joint extends from the retractor blade. The retractor blade and bearing joint are introduced into a surgical site independent of the elongated element. Within the surgical site, the connection nub interconnects with the bearing joint, therein joining the retractor blade to the tubular shaft and a handle.
