Surface pad system for a surgical table

A surface pad system for a surgical table includes a cover having an upwardly-facing patient-support surface defining an interior region of the surface pad system. The surface pad system also includes a vacuum bead bag received in the interior region. The vacuum bead bag includes a flexible cover defining an interior region containing compressible beads. The surface pad system further includes a bladder received in the interior region of the cover and positioned to lie beneath the vacuum bead bag. The bladder defines an interior region and is inflatable when pressurized fluid is received in the interior region of the bladder so that the vacuum bead bag conformingly engages the patient on the patient-support surface when the bladder is inflated.
