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.
Claims27
An apparatus for supporting a patient during a medical procedure;
- the apparatus comprising:
- a) a base with first and second spaced opposed telescoping end supports, each end support having a rotation mechanism;
- and
- b) an elongate patient support structure extending between and being supported by the first and second end supports;
- the elongate patient support structure including first and second frame sections joined inwardly by a pair of spaced apart movable hinges and alignable in a first plane;
- wherein at least one of the frame sections includes a pair of opposed side portions spaced apart so as to receive a belly of a patient therebetween when the patient is in a prone position on the patient support structure;
- wherein
- c) the rotation mechanisms operable to move the patient support structure to a plurality of lockable selectable tilt positions relative to the first plane, the rotation mechanisms substantially resisting a force on both ends applied to the patient support structure when in a tilt position, so as to stabilize the patient during the medical procedure.
An apparatus for supporting a patient during a medical procedure, the apparatus comprising:
- a) a support subassembly including first and second spaced opposed upright end supports;
- each end support being attached to a respective base structure;
- at least one of the first and second end supports being vertically height adjustable;
- b) an elongate patient support with first and second ends and extending between the first and second end supports;
- the patient support being held by the end supports in spaced relation with respect to a floor, the patient support connected to and supported between the end supports;
- the patient support having a single breaking location spaced from the end supports and adapted to interact with the patient when the patient is located on the patient support;
- c) a vertical elevator connecting a patient support first end with a respective end support;
- the vertical elevator being controllable to allow infinite adjustment of the patient support first end relative to the respective end support so as to align and orient the patient support subassembly;
- and
- d) a rotation mechanism positioned between at least one of the upright end supports and the patient support and operable to move the patient support to a plurality of selectable and lockable tilt orientations relative to a first plane, wherein the tilt orientation substantially resist a force applied to the patient during a surgical procedure;
- wherein
- e) the patient support is controllable to be at least upwardly articulatable at both the first and second ends of the patient support relative to respective end supports and at the breaking location so as to be adapted to manipulate a patient into a plurality of selectively prone and non-prone positions in cooperation with a support subassembly translation compensation mechanism, while also cooperating with the end supports to move the patient between vertical positions.
An apparatus for supporting a patient during a medical procedure, the apparatus including a base and a patient support structure attached at both ends thereof to the base and suspended therebetween above the floor, the improvement comprising:
- a) at least one end of the base is adapted to provide for a primary, secondary and tertiary vertical height adjustments for the patient support structure with respect to the floor;
- b) at least one end of the base is adapted for fixing the patient support structure in a plurality of rolled orientations, such that a surgical procedure can be performed upon a patient supported on the patient support structure while the patient support structure is in one of the rolled orientations.
A patient support system including a base with head and foot support columns, and a patient support structure attached at both ends thereof to a respective support column and suspended therebetween a distance above the floor, the patient support structure including head and foot end frame portions joined with one another by a pair of spaced opposed hinge structures, the improvement comprising:
- a) a hinge actuation structure joining each of the hinges with the foot support column, the hinge actuation structure including a cam structure adapted for upward and downward breaking of the respective hinge;
- wherein
- b) when the hinge breaks downwardly, the cam structure translates toward the head support column, and when the hinge breaks upwardly, the cam structure translated toward the foot support column.
