ABSTRACT:
An apparatus for locking an wheeled table into a fixed location is disclosed. The base of the table is provided with both an electric motor coupled to a hydraulic pump and a manually operated hydraulic pump either of which may provide a source of pressurized hydraulic fluid. Extendable and retractable legs are provided on the base of the surgical table. Hydraulic cylinders disposed adjacent to each of the legs are provided with upper link members pivotally attached to the table's base and lower link members which are pivotally attached to the deployable legs. When pressurized hydraulic fluid is provided by the electrically driven or manually powered hydraulic pumps, the hydraulic cylinders disposed adjacent to the deployable legs are extended. Such extension is translated by means of the respective upper and lower link members into a vertical movement which lowers the supporting legs to fix the table in a specified location.
