Patient positioning support structure

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, the first member operably coupled to the first segment near the first end, wherein displacement along the longitudinal length results in a distance between the first end of the first segment of the patient support and the first vertical column changing as the first segment and second segment articulate relative to each other about the joint;
• and
• ii) a first pivot located between the first end of the first segment of the patient support and the first vertical column;
• and
• 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 the 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.
