Claim:
A retractor system, comprising: a frame rail having a cross section defining first and second widened sections, each of said first and second widened sections having opposing surfaces, said first and second widened sections separated relative to each other by a narrowed portion; a supporting frame arm; a frame arm clamp connectable to said frame arm, and having opposed clamping surfaces each shaped to conformingly engage said opposing surfaces of said first widened section, said frame arm clamp further including a connector connecting said opposed clamping surfaces and configured to move said clamping surfaces into conforming contact with said opposing surfaces; and at least one device clamp having opposed clamping surfaces each shaped to conformingly engage said opposing surfaces of said second widened section, said device clamp further including a connector connecting said opposed clamping surfaces and configured to move said clamping surfaces into conforming contact with said opposing surfaces, said at least one device clamp slideable along said second widened section when said at least one device clamp is conformingly engaged with said second widened section and movable past said frame arm clamp when said frame arm clamp is conformingly engaged with said first widened section.
