Abstract

An apparatus is disclosed. The apparatus includes an operating table column head assembly, a patient support surface assembly that is movable relative to the operating table column head assembly, and an actuating cylinder configured to move the patient support surface assembly relative to the operating table column head assembly, the actuating cylinder including a piston rod. A first gear rack is attached to the operating table column head assembly and a second gear rack is attached to the patient support surface assembly. A gear assembly is disposed on the piston rod of the actuating cylinder. The gear assembly engages with the first gear rack and the second gear rack. The first gear rack and the second gear rack move in substantially opposite directions relative to the gear assembly, when the actuating cylinder is actuated.
