ABSTRACT:
A surgical retractor for adjustable mounting on a supported holder includes an elongated stem of cylindrical cross-sectional configuration and blade means attached to one end of the stem, the stem being optionally provided with a plurality of spaced circumferential first means for selective engagement by adjustable complemental second means for restraining longitudinal movement of the stem in one direction, and optionally including an inner section hingedly connected to an outer section, providing a handle for pulling or rotating the retractor.
A holder for a surgical retractor and frame support for the holder assume a nonrotating relation where the frame support has a section of substantially cylindrical cross-sectional configuration and has a longitudinally extending indentation, a portion of the frame support is encompassed by a section of the holder, and the holder section has protruding means for engaging the indentation of the frame support section.
