Abstract

A surgical table comprising a base and a patient support supported between opposed ends of the base, each opposed end including a pitch/roll assembly. The base is configured such that the patient support can be rolled and pitched relative to the opposed ends via the pitch/roll assemblies such that the roll axis of each pitch/roll assembly remains coaxial regardless of how the patient support is pitched or rolled relative to the base. The patient support includes an outer frame and an inner frame supported on, and displaceable relative to, the outer frame. The inner frame is further articulating about, and relative to, itself. The outer frame is rigid in that it does not change configurations.

Dependent claims

A surgical table comprising:

a first column;
a second column;
an outer frame extending along a longitudinal axis between a head end and an opposite foot end, the head end being coupled to the first column such that the head end is movable relative to the first column along a height of the first column, the head end defining a first slot, the foot end being coupled to the second column and defining a second slot, the first slot being linear between opposite ends of the first slot;
an inner frame mounted on the outer frame, the inner frame comprising opposite first and second ends and a joint between the first and the second end such that the second end is pivotable relative to the first end about the joint, a portion of the second end being positioned in the second slot;
and
a drive assembly comprising a drive link having a first end coupled to the joint and an opposite second end positioned in the first slot such that the portion of the second end of the inner frame is slidable within the second slot and the second end of the drive link is slidable relative to the outer frame along the longitudinal axis to pivot the second end of the inner frame relative to the first end of the inner frame,
wherein the inner frame is supported off of and displaceable relative to the outer frame.

A surgical table comprising:

a first column;
a second column;
an outer frame extending along a longitudinal axis between a head end and an opposite foot end, the head end being coupled to the first column such that the head end is movable relative to the first column along a height of the first column, the height of the first column being fixed, the head end defining a horizontal slot extending parallel to the longitudinal axis, the foot end being coupled to the second column and defining a transverse slot extending at a non-zero angle relative to the longitudinal axis;
an inner frame movably coupled to the outer frame, the inner frame comprising opposite first and second ends and an articulation joint between the first and the second end such that the second end is pivotable relative to the first end about the articulation joint, a portion of the second end being positioned in the transverse slot;
a slider joint movably coupling the inner frame to the outer frame such that the inner frame is slidably displaceable relative to the outer frame;
and
a drive assembly comprising a drive link having a first end coupled to the articulation joint and an opposite second end positioned in the horizontal slot such that the portion of the second end of the inner frame is slidable within the transverse slot and the second end of the drive link is slidable relative to the outer frame along the longitudinal axis to pivot the second end of the inner frame relative to the first end of the inner frame,
wherein the inner frame is supported off of and displaceable relative to the outer frame.

A surgical table comprising:

a first column;
a second column;
an outer frame extending along a longitudinal axis between a head end and an opposite foot end, the head end being coupled to the first column such that the head end is movable relative to the first column along a maximum height of the first column, the maximum height of the first column being permanently fixed, the head end defining an elongated horizontal slot extending parallel to the longitudinal axis, the foot end being coupled to the second column and defining an elongated transverse slot extending at an acute angle relative to the horizontal slot;
an inner frame mounted on the outer frame, the inner frame comprising opposite first and second ends and an articulation joint between the first and the second end such that the second end is pivotable relative to the first end about the articulation joint, a portion of the second end being positioned in the transverse slot;
a slider joint movably coupling the inner frame to the outer frame such that the inner frame is slidably displaceable relative to the outer frame;
and
a drive assembly comprising a drive link having a first end coupled to the articulation joint and an opposite second end positioned in the horizontal slot such that the portion of the second end of the inner frame is slidable within the transverse slot and the second end of the drive link is slidable relative to the outer frame along the longitudinal axis to pivot the second end of the inner frame relative to the first end of the inner frame,
wherein the inner frame is supported off of and displaceable relative to the outer frame.
