Abstract

A surgical retractor with interchangeable retractor blades allows the retractor blades to be positioned in an incision before being side-loaded into the retractor body and locked in place. The surgical retractor uses a nipple connector with a conical base and a rounded head which fits into and self-aligns in a corresponding socket.
