ABSTRACT:
An adjustable limb support system is provided for an operating room table to adjustably orient and position a stirrup or boot. The support system provides an adjustable support in combination with a vertically adjustable support. The vertically adjustable support includes a support arm, a ratchet wheel, a lock pin, and a ratchet release. The support arm is connected to a housing which both rotate about the ratchet wheel in a rotational plane extending upwardly and outwardly from the operating room table for automatic abduction. The lock pin engages the ratchet wheel and allows the support arm to be rotated upwardly but not downwardly. The ratchet release disengages the lock pin and allows the support to be rotated downwardly. The support arm can thus ratchet upwardly to fixed vertical positions and be lowered only by disengaging the lock pin. The adjustable support includes a retaining block, a compression block, and a compression head. The retaining block defines a passage for receiving a connecting rod secured to the stirrup or boot. The compression block defines a passage for receiving the support arm of the vertical adjustable support. The compression head when tightened prevents translation and rotation of the compression block on the support arm, and rotation of the compression block and the retaining block relative to each other. When the compression head is untightened the compression block can be translated or rotated on the support arm, and the blocks can be rotated relative to each other, in order to orient and position the stirrup or boot. The stirrup or boot freely rotates or swings about the axis of the connecting rod at all times.
