ABSTRACT:
A clamping device for use in a surgical retractor support includes a first clamp member for clamping a first retractor support. The first clamp member has a first opening that is disposed along a longitudinal axis of the first retractor support for receiving the first retractor support. A pin disposed within the clamp member has a cam surface for acting on the first retractor support member. A handle operable with the pin for moving the cam surface between a first nonlocking position and a second locking position for locking the first retractor support member from movement. Preferably a wedge section is positioned between the cam surface and the first retractor support such that the wedge section frictionally engages the first retractor support when the cam surface is in the second locking position. The clamping device also has a second clamp member for clamping a second retractor support.
