ABSTRACT:
A self-retaining hand-held surgical retractor includes a main pair of blades mounted to a pair of fulcrumed levers. The proximal ends of two longitudinally extending bars are mounted to a toggle link carried between the handles. The bars pass through arms projecting from the levers above the plane containing the levers. A pair of supplemental blades are mounted to the bars. Closing the handles directly causes both the main pair of blades and the supplemental pair of blades to recede from each other, and also causes the supplemental pair of blades to move rearwardly from the main pair of blades through the action of the toggle link.
