Surface pad system for a surgical table

A surface pad system for a surgical table, the surface pad system comprising:

• a cover having an upwardly-facing patient-support surface defining an interior region of the surface pad system,
• a vacuum bead bag received in the interior region, the vacuum bead bag including a flexible cover defining an interior region containing compressible beads,
• a bladder received in the interior region of the cover and positioned to lie beneath the vacuum bead bag, the bladder defining an interior region and being 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,
• a vacuum source,
• a controller coupled to the vacuum source for controlling the pressure in the interior region of the vacuum bead bag,
• a source of pressurized fluid in fluid communication with the bladder, the controller being coupled to the source of pressurized fluid for controlling the pressure in the interior region of the bladder so that the controller can coordinate the operation of the vacuum bead bag and the bladder,
• a thermal pad received in the interior region of the cover, and
• a heat exchanger coupled to the thermal pad, the thermal pad including a channel in fluid communication with the heat exchanger and receiving thermoregulation fluid therefrom, the controller being coupled to the heat exchanger to control the temperature of the thermoregulation fluid, thus controlling the temperature of the patient-support surface.

A surface pad system for a surgical table, the surface pad system comprising

• a cover defining an interior region, a top having an upwardly-facing patient-support surface, and a bottom having a downwardly-facing bottom surface spaced apart from the patient-support surface,
• a high density foam first support layer received in the interior region and engaging the bottom of the cover,
• a bladder received in the interior region and engaging the first support layer,
• a lower layer of positioning beads received in the interior region and engaging the bladder, the lower layer of positioning beads including a plurality of transversely extending elongated tubes made from a flexible material, each tube defining an interior region receiving beads,
• an upper layer of positioning beads received in the interior region and engaging the lower layer of positioning beads, the upper layer of positioning beads including a plurality of longitudinally extending elongated tubes made from a flexible material, each tube defining an interior region receiving beads,
• a high density foam second support layer received in the interior region and engaging the upper layer of positioning beads,
• a thermal pad received in the interior region and engaging the second support layer, the thermal pad including a casing defining a serpentine channel receiving a thermoregulation fluid at a selected temperature,
• a gel layer received in the interior region and engaging the thermal pad, the gel layer including a casing defining an interior region containing a viscous fluid, and
• a cut-proof material layered between the gel layer and the top of the cover to prevent the penetration of the gel layer by objects that penetrate the top of the cover.

A vacuum bead bag for use in a surface pad system for a surgical table, the vacuum bead bag comprising

• a casing having an interior region,
• a plurality of elongated flexible tubes received in the interior region of the casing, each tube defining an interior region of the tube, and
• a plurality of compressible beads, each tube receiving beads of the plurality of compressible beads in the interior region of each tube,
• wherein a first set of tubes of the plurality of tubes includes tubes extending in a first direction and a second set of tubes of the plurality of tubes is positioned to lie above the first set of tubes, the second set of tubes including tubes extending in a second direction, the second direction being generally perpendicular to the first direction.
