Modular multi-articulated patient support system

摘要

A modular, multi-articulated patient support system includes independently adjustable columns connected by an adjustable base and supporting a patient support structure. Each column includes rotation, angulation and separation adjustment structure. The patient support may be raised, lowered and rotated about a longitudinal axis in either horizontal or tilted orientation. The patient support includes a body support rotatably coupled with right and left leg supports disengageable at the outboard ends, that can be tilted, rotated and locked in place. An intermediate brace engages the base when the outboard ends of the leg supports are disengaged. The patient support structure may include two pairs of patient supports, each attached at the outboard end of a column and having a free inboard end. A coordinated drive system raises, lowers, tilts and rotates the patient supports, which may be positioned in overlapping relation. The pairs of patient supports may be rotated in unison to achieve 180° repositioning of a patient.

主权项

1. A surgical table comprising: 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 together to define a joint about which the first segment and second segment articulate relative to each other; and a first support structure comprising a first vertical column and 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 between the first vertical column and the first end of the first segment of the patient support, 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; and b) a first angulation assembly operably coupled between the first vertical column and the first end of the first segment of the patient support, the first angulation assembly configured to angle the first segment of the patient support relative to the first vertical column, the first angulation assembly comprising: i) a first member operably coupled to the first vertical column via a first pivot; ii) a second member operably coupled to the first end of the first segment of the patient support and pivotally coupled to the first member via a second pivot; and iii) a third pivot near an intersection between the first end of the first segment of the patient support and the second member.
