Abstract

A patient support system includes independently adjustable end columns supporting a centrally hinged, jointed or breaking patient support structure. At least one column includes a powered rotation assembly. The patient support includes at least two sections. A coordinated drive system provides for both upwardly and downwardly breaking or jointed orientations of the two sections in various inclined and tilted positions. Cable, cantilevered and pull-rod systems are included.

Claims

1. A table apparatus for supporting a patient during a medical procedure, comprising:

a) an elongated patient support structure suspended above a floor by opposed table apparatus outer end supports that are spaced a first distance apart and supported on the floor, the patient support structure having;

i) separate head and foot portions, each portion being supported by a respective table apparatus outer end support near outward ends of the head and foot portions and having an inward end, the outward ends being a spaced second distance apart;

ii) an articulation at the inward ends of the patient support structure, the head and foot portions being pivotably connected at the articulation; and

iii) a rotation subassembly above each outward end portion of the patient support structure providing a roll axis along each outward end portion;

wherein;

b) when the head and foot portions pivot at the inward articulation into a plurality of angular orientations, both outward ends of the patient support structure translatingly move between one of being a closer and a further spaced distance apart relative to each other and their respective outer end support; and

wherein

c) the table apparatus outer end supports are stationary with respect to the floor so that the spaced first distance apart remains constant.

2. The table apparatus according to claim 1, wherein:

a) each of the table apparatus outer end supports includes at least one lockable structure sized and shaped for locking a longitudinal position of the respective table apparatus outer end support relative to each other.

3. The table apparatus according to claim 2, wherein:

a) the lockable structure is a caster.

4. The table apparatus according to claim 1, wherein:

a) the table apparatus outer end supports are connected to each other by a longitudinally extending structure extending therebetween.

5. The table apparatus according to claim 1, wherein:

a) the plurality of angular orientations is formed at the articulation and at the head and foot portions with respect to the outward end connections at the table apparatus outer end supports by activation of an actuator to actively move the articulation.

6. The table apparatus according to claim 1, wherein:

a) each of the table apparatus outer end supports includes a vertical height adjustment mechanism with respect to the floor.

7. The table apparatus according to claim 1, wherein:

a) when the outward ends of the patient support structure move closer together, the articulation breaks in one of an upward direction and a downward direction.

8. The table apparatus according to claim 1, wherein:

a) the outward ends are actively pulled inwardly when translatingly moved so as to get closer together.

9. A table apparatus for supporting a patient during a medical procedure, comprising:

a) an articulatable elongated patient support structure having a pair of outer ends and a centrally located pivot structure sized and shaped to allow articulation of the patient support structure;

b) a pair of spaced apart support columns supporting the patient support structure therebetween; and

c) a rotation subassembly above each outer end of the patient support structure providing a roll axis along each outer end, wherein

d) when the patient support structure articulates at the pivot structure,

i) the patient support structure outer ends are both actively moved away from the support columns; and

ii) the support columns are stationary.

10. The table apparatus according to claim 9, wherein:

a) the pivot structure includes a pair of spaced apart hinges.

11. The table apparatus according to claim 9, further wherein:

a) when the patient support structure articulates at the pivot structure,

i) a height of the pivot structure above a floor is substantially constant; and

ii) at least one of the outer ends of the patient support structure moves vertically.

12. A table apparatus for supporting a patient during a medical procedure, comprising:

a) an elongated patient support structure suspended above a floor by opposed table end supports a spaced distance apart along a longitudinal axis, the end supports each having a roll axis, the patient support structure having;

i) separate head and foot portions, each portion being supported by a respective table end support near an outer end thereof; and

ii) an inward articulation near a center of the patient support structure, the head and foot portions each having an inner end positioned near each other and being directly pivotably connected at the articulation;

wherein

b) when the head and foot portions pivot at the inward articulation, both outer ends of the patient support structure are each moveable inwardly in a direction along the longitudinal axis, so as to get closer together and the table end supports are stationary with respect to the spaced distance apart along the floor; and

wherein each end support roll axis is located above each head and foot portion outer end.
