Surgical patient support for accommodating lateral-to-prone patient positioning
According to the present disclosure, a surgical patient support provides support to a patient. The surgical patient support may include configuration to accommodate various patient body positions to provide a variety of access to the patient's body.
1. A surgical patient support extending from a head end to a foot end,
the surgical patient support comprising:
a support frame including first and second support rails extending parallel to each other between the head end and the foot end, a head-cross beam and a foot-cross beam connected to each of the support rails at the head end and foot end respectively, and a connection arm engaged with the head-cross beam, the first and second support rails each including a torso rail and a leg rail, the torso rails each extending from the head-cross beam towards the foot end to connect with the leg rail of the respective support rail, and each leg rail extends from connection with the torso rail of the respective support rail towards the foot end, each leg rail includes a first sub-rail and a second sub-rail, and each first sub-rail extends from connection with the torso rail of the respective support rail towards the foot end at an angle relative to the torso rail of the respective support rail and each second sub-rail extends from connection with the foot-cross beam for connection with the first sub-rail of the respective support rail,
a platform mounted on the support frame and including a torso section and a leg platform including a pivot end pivotably attached to the frame and a footward end proximate to the foot end of the patient support, the leg platform being configured to move between a raised position in which the leg platform is generally parallel with the torso platform and a lowered position in which the leg platform is pivoted out of parallel with the torso platform,
an actuator assembly coupled to the support frame and configured to support the leg platform, and
a protection sheath coupled to the second sub-rail of each of the leg rails to block against pinch point formation during movement of the leg platform.
2. The surgical patient support of claim 1 , wherein the protection sheath includes a tray extending between opposite ends and an arm attached to each of the opposite ends of the tray.
3. The surgical patient support of claim 2 , wherein the tray is formed to have a shape that corresponds closely to the travel path of the leg platform between the raised and lowered positions to prevent pinch points.
4. The surgical patient support of claim 2 , wherein the arms each define an opening and a cavity extending from the opening into the respective arm, each arm being configured to receive one of the second sub-rails through the respective opening and into the respective cavity.
5. The surgical patient support of claim 4 , wherein the tray includes an opening defined on a rear side thereof and a cavity extending from the opening into the tray for receiving the foot-cross beam therein.
6. The surgical patient support of claim 5 , wherein the connection arm extends through the opening in the tray.
7. The surgical patient support of claim 5 , wherein the cavities of the arms connect with the cavity of the tray.
8. The surgical patient support of claim 1 , wherein each first sub-rail extends from connection with the torso rail of the respective support rail towards the foot end at an angle of about 15 to about 35 degrees relative to the torso rail of the respective support rail.
9. The surgical patient support of claim 1 , wherein in the lowered position the leg platform of the platform is parallel to the first sub-rails.
10. The surgical patient support of claim 1 , wherein the actuator assembly includes a linear actuator configured for movement between a retracted position and an extended position to move the leg section of the support platform between the lowered position and the raised position.
11. The surgical patient support of claim 10 , wherein the linear actuator is situated about midway between the leg rails.
12. The surgical patient support of claim 1 , wherein the protection sheath is formed as a shovel-shaped guard that extends between the second sub-rails of the leg rails.
13. The surgical patient support of claim 1 , wherein the protection sheath has an external surface that is formed to include a curvature along a direction generally parallel with the second sub-rails.
14. The surgical patient support of claim 1 , wherein the protection sheath has an external surface that is formed to include a curvature along a direction generally perpendicular with the second sub-rails.
15. The surgical patient support of claim 1 , wherein the protection sheath has an external surface that is shaped to conform to a path of travel of the footward end of the leg platform.
16. The surgical patient support of claim 1 , wherein the protection sheath is embodied has a hollow shell that receives the second sub-rails and the foot-cross beam.
17. The surgical patient support of claim 16 , wherein the protection sheath is made of a plastics material.
18. The surgical patient support of claim 16 , wherein the protection sheath is formed to include a plurality of divots that extend from a rear wall of the hollow shell toward a front wall of the hollow shell.
19. The surgical patient support of claim 18 , wherein the divots serve to rigidify the hollow shell due to contact between the divots and the front wall of the hollow shell that limits flexion of the front wall of the hollow shell.
20. The surgical patient support of claim 18 , wherein the plurality of divots comprises three divots.
