[57] ABSTRACT

A surgical table is provided which is capable of conventional surgical table functions and is provided with a radioluscent tabletop which may be horizontally displaced to allow radiographic procedures to be performed without requiring relocation of the patient. The surgical table includes a base member which may be locked to a floor mount pivot. The base member supports a table superstructure which may be raised and lowered and tilted relative to the longitudinal axis of the table as well as tilted relative to a lateral axis of the table. A carriage assembly is provided intermediate the tabletop and the superstructure which allows the translation of the tabletop both longitudinally and laterally. Locking means are provided to prevent the horizontal translation of the tabletop when the table is in the surgical mode. Control means are provided to select either the surgical mode in which the tabletop is locked to the superstructure or the translation mode in which the tabletop may be translated relative to the superstructure. In the translation mode the table is locked to the floor bracket and the tabletop may be displaced relative to the superstructure. In addition, means are provided for automatically returning the table to a level condition either in the surgical mode or in the translation mode.
