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.

主权项

1. A surgical table comprising:
A) a patient support comprising a first segment and a second segment, the first segment comprising a first end and a second end opposite the first end, the second segment comprising a third end and a fourth end opposite the third end, the first and fourth ends forming opposite ends of the patient support, the second and third ends coupled to together to define a joint about which the first segment and second segment articulate relative to each other; and B) a first support structure comprising a first vertical column and supporting a first displacement apparatus operably coupling the first vertical column to the first end of the first segment of the patient support, the first displacement apparatus comprising:
a) a first rotation assembly operably coupled to the first vertical column, the first rotation assembly configured to rotate the patient support relative to the first vertical column and about an axis parallel to a longitudinal axis of the patient support;b) a first angulation assembly configured to facilitate the first segment articulating relative to the second segment about the joint, the first angulation assembly comprising:
i) a first member comprising a longitudinal length extending generally parallel to a longitudinal length of the first segment of the patient support; andii) a second member operably coupled to the first segment of the patient support near the first end of the first segment, the second member configured to displace along the longitudinal length of the first member as the first segment and second segment articulate relative to each other about the joint;c) a first structure operably coupling the first rotation assembly to the first member, the first structure extending downward from the first rotation assembly to the first member when the patient support faces generally upward, wherein the first member is operably coupled to the first structure via a first pivot, the first end of the first segment pivoting relative to the first vertical column about the first pivot when the first segment articulates relative to the second segment about the joint.
