Abstract
A surgical table is disclosed which includes a base and a first planar table surface which is fixedly mounted to the base. A second planar table surface is mounted to the base by means of a linear guide such that the second table surface is positioned in the plane of the first table surface and is movable toward and away from the first table surface. A third table surface is interconnected between the first and second table surfaces. This third table surface is formed of a bendable material and is provided with a cylindrically convex shape. The radius of curvature of this convex shape varies as a function of the linear position of the first table surface with respect to the second table surface. Preferably, the third table surface is formed of an X-ray transparent material. Articulated leg brackets allow the height and tilt angle of the table to be adjusted. The disclosed surgical table is particularly useful in positioning the spine of a patient as necessary for certain surgical procedures in which a needle must be inserted into a disc between two adjacent vertebra.
