Abstract: A surgical retractor apparatus comprising a U-shaped thread assembly slidably engaged with a U-shaped rack. A rotatable threaded rod connects the U-shaped rack and the U-shaped thread assembly. A first swivel having a first blade mount is rotatably connected to the U-shaped rack and a second swivel having a second blade mount is rotatably attached to the thread assembly. A first blade is mounted in the first blade mount and a second blade is mounted in the second blade mount. The swivels have respective threaded screws to adjust the angle of each blade relative to a longitudinal plane passing through the U-shaped rack.
