System for prone positioning of surgical patients

A patient support system for supporting a patient during surgery comprising:

• a support frame;
• and a plurality of patient supports removably attached to the support frame, wherein the support frame is removably attachable to a surgical table by a flexible waterproof strap that passes around a surgical rail on the surgical table, wherein the waterproof strap is connected at one end to the support frame and removably attached to the support frame at its other end and wherein the waterproof band or strap has holes formed therein;
• and
• at least two strap brackets each having a stand-off mounted to an upper surface of the support frame such that the strap can be looped around a surgical table side rail and looped over and through the strap bracket and attached to stand off.

A patient support system for supporting a patient during surgery comprising:

• a support frame;
• a plurality of patient supports;
• a moveable carriage mounted to the support frame, the moveable carriage being movable along a first direction and a second direction relative to the support frame, the moveable carriage comprising mount blocks on which the patient supports are mounted;
• and
• an actuation mechanism that causes movement of the moveable carriage in the first and second directions,
• said patient supports removably attached at one end to the support frame and attached at another end to the movable carriage, wherein the mount blocks are rotatable independent of any movement of the movable carriage in the first and second directions, wherein the moveable carriage comprises a support rod, the mount blocks being movable along the support rod to adjust a distance between the patient supports, wherein the mount blocks are rotationally supported on the support rod, and the moveable carriage further comprises actuation mounts corresponding to each of the mount blocks and supported on the support rod, wherein when a mount block is rotated relative to the support rod, the actuation mounts do not rotate relative to the support, and wherein each of the actuation mounts comprise an actuation button assembly and an actuation button, wherein when a mount block is rotated relative to the support rod by actuating the actuation button, the actuation button assembly and actuation button do not rotate relative to support rod and relative to the frame.
