Adjustable frame for supporting surgical tray - attached to operating table, is supported by mechanical linkages on two vertical adjustable posts

摘要

The frame consists of two upright supporting columns, one attached to each side of the operating table at an appropriate position. A horizontal bar is mounted between the upper ends of the upright supporting columns and extends a cross the operating table. A rectangular open frame is supported by mechanical linkages to a pair of vertically-extending posts adjustably mounted, respectively upon two slidable blocks carried by the horizontal bar. A removable surgical tray is clamped on the open rectangular frame. The position of the surgical tray may be raised and lowered over the patient, and may be moved about in a plane, or may be tilted or inclined as needed.
