ABSTRACT:
A clamp assembly suitable for simultaneously adjusting the positions of support rods on an operating table extension in a split wishbone surgical retractor apparatus. Two independently rotatable disks are coaxially stacked on a base and tightened together by a bolt and T-shaped fitting extending through central openings of the base and disks. Channels formed between the disks and the base loosely receive the rods, and aligned bores in the base and the fitting loosely receive the extension. As the bolt and fitting are tightened, the rods and extension are clamped in fixed relative positions. The disks are interlocked at discrete angular positions by a pin and holes for adjusting the spread between the rods.
