Abstract: These systems and devices can be placed on top of any commercially available standard operating table and therefore can provide a portable and inexpensive alternative to commercially available specialized operating tables. The system may include a frame body having a first end, a second end, and a length therebetween. The system may also include one or more movable platforms having a first end, a second end, and a length therebetween. Each moveable platform may be configured to move between the first end and the second end of the frame body. The system may also include one or more stabilizing support members disposed parallel to the first end and the second end of the frame body and configured to move along the length of the movable platform. Each stabilizing support member may include one or more securing members configured for removable, active and/or removable fixation with respect to the movable platform.
