Patient positioning support structure

摘要

A patient support system includes independently adjustable end columns supporting a centrally hinged, jointed or breaking patient support structure. At least one column includes a powered rotation assembly. The patient support includes at least two sections. A coordinated drive system provides for both upwardly and downwardly breaking or jointed orientations of the two sections in various inclined and tilted positions. Cable, cantilevered and pull-rod systems are included. Primary and secondary elevators and a failsafe locking system are provided.

主权项

1. A patient support apparatus for supporting a patient above a floor during a medical procedure, the apparatus comprising:
a) an elongate patient support having first and second ends and a head portion and a foot portion that are joined by a pair of spaced opposed hinge structures, articulatable with respect to each other and lockable in a planar configuration and a plurality of angular configurations relative to each other; b) a first end support connected to the patient support first end, and being vertically adjustable so as to provide for selective positioning of the first end relative to the floor supporting the apparatus; c) a torso trolley movably positionable upon the patient support head portion, wherein the torso trolley is adapted to support the torso of a patient on the apparatus; d) a trolley positioner operably determining an articulation between the head and foot portions and cooperatively positioning the trolley on the head portion in a predetermined location relative to the head portion in response to the determined articulation; and e) a secondary vertical elevator located between the first end and the first support to provide vertical adjustment of the first end relative to the floor in cooperation with the first support.
