Abstract
A retractor apparatus having a hollow rod member and a clamping device is provided. Support members are adjustably secured to the hollow rod member. The clamping device includes a first member having a first clamping portion and a second member having a second clamping portion. The second member is pivotally attached to the first member. When the second member is pivoted into a clamping position with the first member, the first and second portions clamp a side rail of an operating table. A tightening mechanism retains the first and second clamping portions in the clamping position. The first member has a passage for receiving the hollow rod member.
