Patient positioning support apparatus with virtual pivot-shift pelvic pads, upper body stabilization and fail-safe table attachment mechanism
First Claim
1. A base for supporting and positioning a patient support structure above a floor, the patient support structure configured to support a patient'"'"'s body, the base comprising:
- a) a pair of spaced opposed upright end supports, each end support adapted to releasably attach to an outer end of the patient support structure via a connection assembly;
b) a central longitudinal connecting structure extending between the end support columns; and
c) each end support is off-set on opposite sides of the central longitudinal connecting structure.

Abstract
A patient support apparatus for supporting a patient in a prone position during a surgical procedure includes a patient support structure incorporating 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 pivot point, the joints being movable along the arc providing a pivot-shift mechanism for a pair of pelvic pads attached to the joints. A base supports and suspends the 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 the 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.

11. A base for supporting and positioning a patient support structure above a floor, the base comprising:
-
a) a pair of spaced opposed upright support columns; b) a central longitudinal connecting structure extending between the pair of support columns; c) each of the pair of support columns is off-set on opposite sides of the central longitudinal connecting structure; and d) the pair of support columns is adapted to rotate the patient support structure with respect to a roll axis so as to be rolled an amount of about 180-degrees, so as to position the patient support structure in an inverted orientation.
