Abstract: A surgical retractor particularly for retracting an internal organ such as the liver during surgery. A ladder-like support is designed to fit a universal clamp on the operating table and a rigid elongated strip of material is positioned over a selected one of the ladder rungs. The strip comprises a plurality of spaced hooks which hook over a respective rung and the retractor end of the strip is curved to fit around an organ such as the liver. In operation, the particular height rung is selected for height and the strip is positioned to hook onto the rung depending upon the selected length of the strip desired with respect to the patient. Adjustment may be effected quickly and easily during surgery.
