Surgical table hydraulic system
First Claim
1. A surgical table comprising:
- a first double acting hydraulic motor connected to a vertically movable table support;
a second double acting hydraulic motor connected to a table section mounted on said support and adapted to pivot about a horizontal axis;
means for supplying hydraulic fluid under pressure to said first hydraulic motor or to said second hydraulic motor;
means for connecting either said first hydraulic motor or said second hydraulic motor to a hydraulic fluid reservoir; and
means for connecting said first motor and said second motor in series between said fluid supply means and said fluid reservoir.

Abstract
The disclosed surgical table hydraulic system uses a plurality of double acting hydraulic motors, such as double-ended hydraulic cylinders or reversible rotary hydraulic motors, that can be operated either independently or in synchronization. Each of the motors can be connected to a source of pressurized hydraulic fluid, and to a reservoir, for independent action. At least some of the motors can also be connected in a hydraulic series between the hydraulic fluid supply and the reservoir for synchronous operation. In this way, separate elements of the table, controlled by the individual hydraulic motors, can be moved in unison. Also, by operating two motors that control different types of motion, such as elevation of a table and tilting about a horizontal axis, compound motions of one or more sections of the table can be provided.
