## Abstract

An improved medical procedure table has motorized elevation, Trendelenburg tilt, floating tabletop with both longitudinal and lateral travel, multi-caster control, and an iso-roll device for the tabletop. The iso-roll device is connected between a roll plate and a cross plate. The iso-roll device includes a pair of iso-roll guide plates, which are mounted laterally to a bottom of the roll plate. Each iso-roll guide plate has an arcuate guide channel therein having an upwards concave shape. A set of cam followers are positioned in both guide channel and travel therein and also fixedly mounted to a base on the cross plate. A center of radius of the arcuate guide channel is approximately 5 inches above the tabletop. Further, mounted between the iso-roll guide plates and to the roll plate is a support guide plate having an arcuate bottom surface.

## Claims

### Claim 1

A table for medical procedures having a tabletop, and a base, and a support column, said support column operatively connected to said tabletop, said tabletop being cantilevered thereon, wherein an iso-roll device in the support column comprises:
two arcuate channels for moving the table top about an iso-roll axis above the plane of the tabletop, each channel being mounted in a guide plate, and said guide plates being mounted to a roll plate, support rollers mounted within said two arcuate channels and being fixedly mount to a cross plate, and also including a support guide plate, said support guide plate being mounted to said roll plate, said support guide plate having an arcuate bottom surface for the purpose of insuring stability of the tabletop and in rolling contact with said cross plate, wherein said iso-roll device further includes:
said cross plate having mounted thereunder and thereto transverse/lateral rails which laterally move within rail guides thus allowing the iso-roll device to move laterally upon the support column.

### Claim 2 (depends on 1)

The table for medical procedures as defined in claim 1, wherein an iso-axis is located approximately between 2 and 12 inches from the tabletop surface.

### Claim 3 (depends on 2)

The table for medical procedures as defined in claim 2, wherein said iso-axis is located approximately 5 inches from the tabletop surface.
