Abstract

A patient support apparatus for supporting a patient in a prone position during a surgical procedure is provided, including an open fixed frame suspended above a floor and a pair of spaced opposed radially sliding joints cooperating with the frame, each joint including a virtual pivot point and an arc of motion spaced from the virtual pivot point, the joints being movable along the arc providing a pivot ship mechanism for a pair of pelvic pads attached to the joints. A base for supporting and suspending a patient support structure above the floor, for supporting a patient during a surgical procedure, the base including a pair of spaced opposed vertical translation subassemblies reversibly attachable to a patient support structure, a cross-bar, and a rotation subassembly having two degrees of rotational freedom; wherein a location of each vertical translation subassembly is substantially constant during operation of the patient support structure.

Dependent claims

A base structure for supporting a patient support structure above a floor, the base structure comprising:

a head end support structure comprising a head end lower portion and a head end upper portion, the head end upper portion configured to change elevation relative to the floor;
a foot end support structure opposite the head end support structure and comprising a foot end lower portion and a foot end upper portion, the foot end upper portion configured to change elevation relative to the floor;
a cross-bar extending between the head end support structure and the foot end support structure;
a head end rotation assembly rotatably coupled with the head end support structure, the head end rotation assembly comprising a head end motor, a head end rotation shaft rotatably coupled to the head end motor, and a head end rotation block pivotally coupled to the head end rotation shaft via a head end yaw pin, the head end yaw pin extending through the head end rotation shaft, the head end rotation block configured to operably couple with a head end of the patient support structure, the head end motor configured to rotate the head end shaft, the head end rotation block, and the patient support structure about a head end rotation axis extending through the head end rotation shaft, the head end rotation block configured to pivot about a head end yaw axis extending through the head end yaw pin, the head end rotation axis oriented perpendicular to the head end yaw axis;
and
a foot end rotation assembly rotatably coupled with the foot end support structure, the foot end rotation assembly comprising a foot end motor, a foot end rotation shaft rotatably coupled to the foot end motor, and a foot end rotation block pivotally coupled to the foot end rotation shaft via a foot end yaw pin, the foot end rotation block configured to operably couple with a foot end of the patient support structure, the foot end motor configured to rotate the foot end shaft, the foot end rotation block, and the patient support structure about a foot end rotation axis extending through the foot end rotation shaft, the foot end rotation block configured to pivot about a foot end yaw axis extending through the foot end yaw pin, the foot end rotation axis oriented perpendicular to the foot end yaw axis.
