ABSTRACT:
A surgical retractor according to the invention comprises a straight shaft, a blade and means for pivotally connecting the blade to the shaft with the blade oriented perpendicularly to the shaft and being free to turn about an axis perpendicular to the shaft. The retractor may further comprise means for telescopically adjusting the length of the shaft and releasably fixing the shaft at the adjusted length. A sole may be formed on the free extremity of the blade most remote from the pivotal connection, the sole being symmetrically formed on the blade and defining surfaces in planes perpendicular to the turning axis of the blade, the surfaces extending equally beyond the thickness of the blade in opposite directions.
