Abstract
A surgical retractor for retracting body tissue in a therapeutic procedure includes two lateral arms each having a block with an aperture extending transverse to a longitudinal axis of the arm. The distal end of each arm pivotably supports a retractor blade. A transverse extension, forming a retractor core, extends through the aperture and slideably supports a lateral arm at each end. A central arm also pivotably supports a retractor blade, and has an extension on a proximal end that is insertable into an aperture within the core. The lateral and central arms are translatable in connection with the core. The retractor blades can be pivoted by rotating a tool engagement. A rack and pinion, controlled by a pawl, is used to translate the side and central arms.
