ABSTRACT:
A retractor clamp assembly includes a clamp positionable about a support ring. A retractor shaft extends from the clamp and has a connector at the end with a retractor blade connected thereto by a stem. The connector is preferably equipped with a first slot limiting the side to side angular range of motion of the retractor blade stem relative to the retractor shaft, and a second slot limiting the top to bottom range of motion of the retractor blade stem relative to the retractor shaft. This allows the retractor blade to be maintained and/or positioned in an optimum position relative to retracted tissue while allowing the retractor shaft to be selectively positioned by a user.
