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 connector head with a circumferential groove that fits in a side-loading socket and is locked in place with a cam that fits in the circumferential groove. A release lever releases the cam and allows the retractor blades to be removed.
