Description

[0001] SUPPORT PLATFORM

[0002] TECHNICAL FIELD

[0003] The present technology relates to supports for supporting a body during a procedure such as a surgery or for supporting a cadaver such as during dissection or perfusion.

[0004] BACKGROUND

[0005] During medical interventions, such as clinical procedures performed on living patients or anatomical procedures involving cadavers, significant quantities of bodily fluids such as blood, perfusate, and irrigation liquids are released. Managing these fluids presents persistent challenges in real or simulated surgical environments, research laboratories, and facilities engaged in organ perfusion or post-mortem analysis.

[0006] Conventional operating tables, dissection benches, and cadaver support platforms often rely on flat or minimally contoured surfaces that do not adequately channel or contain fluid. As a result, fluids may pool unpredictably, overflow table edges, or require continuous manual suctioning and cleanup. This ineffective fluid management can lead to contamination of equipment and surrounding areas, increased biohazard exposure to personnel, and greater time needed for sanitation between procedures. Furthermore, in conventional workflows, living patients or cadavers must often be transferred to a different support platform to undergo medical imaging procedures based on X-ray radiation, such as computed tomography or fluoroscopic imaging.

[0007] Accordingly, there remains a need for an improved support platform.

[0008] SUMMARY

[0009] It is therefore an object of the present technology to ameliorate the situation with respect to at least one of the inconveniences present in the prior art. Aspects of the present technology at least partially or fully address these needs.

[0010] From a broad aspect, there is provided a support platform that is configured to manage fluids as well as permit medical imaging, based on X-ray radiation for example, of a body or body part supported by the support platform. In this respect, the present technology permits fluids to be collected for subsequent removal and includes components that are radiolucent.

[0011] 306683293.1Embodiments of the present technology include a first component for supporting a body or body part, and a second component for managing fluids from the body or body part. The second component has a surface that is angled with respect to the first component for ease of collection of the received fluids and subsequent drainage, such as through a drain. In some embodiments, the first component is supported on the second component, the first and second components being in fluid communication through openings in the first component.

[0012] In some aspects, there is provided a support platform including: a first component supported by a second component, the first component has a first component surface; the second component has a second component surface; wherein the second component surface is at an angle to the first component surface. The first and second support components may be referred to as a table portion of the support platform. The table portion may be supported on a support surface such as a stretcher, a bed, a table or the like.

[0013] Advantageously, the support platform is modular. The first component may be separable from the second component for cleaning, maintenance and the like.

[0014] In some embodiments, the first component surface is sized and shaped to support a body or a body part. In some embodiments, the first component surface has an elongate shape. The first component has a longitudinal axis.

[0015] In some embodiments, the first component is made of a radiotransparent (radiolucent) material. The first component may be made of an acrylic plastic, for example. In some embodiments, the second component is made of a radiotransparent (radiolucent) material.

[0016] The radiolucency of the first and second components, and optionally, other components of the support platform permit medical imaging of the body and / or body parts that are supported on the first component surface.

[0017] In some embodiments, there are one or more openings defined in the first component surface. In some embodiments, the first and second components are fluidly connectable through the one or more openings.

[0079] DETAILED DESCRIPTION

[0080] With reference to Figures 1 to 5, there is shown one embodiment of a support platform 10 according to the current technology. The support platform 10 can be used for supporting a body or a body part during clinical interventions such as surgery. The support platform 10 can be used for supporting a cadaver or a part of a cadaver during an intervention during which the 306683293.1cadaver is being perfused. The support platform 10 can be used for any other uses in which it is advantageous to support a body and collect spilled fluids from that body.

[0081] Broadly, the support platform 10 comprises a support body 12 (hereinafter referred to as frame 12), a first component 14 and a second component 16. The second component 16 supports the first component 14. The first component 14 may rest on the second component 16, or be removably connected thereto. In this respect, the first component 14 includes handle cut-outs 15 for ease of removal. The handle cut-outs 15 may also function as openings for fluid to flow from the first component 14. The second component 16 is supported by the frame 12 and is fixedly connected thereto.

[0082] In other embodiments, the first and second components 14, 16, may be fixedly connected together. In some embodiments, the second component 16 may be removably connected to the frame 12. In some embodiments, the second component 16 and the frame 12 may be integral. In yet other embodiments, the frame 12 may be omitted. In other embodiments, the first component 14 may omit the handle cut outs 15 or provide handle cut outs 15 with a different configuration and number than as illustrated.

[0083] The assembly of the frame 12, the first component 14 and the second component 16 is referred to herein as a “table portion” of the support platform 10. In embodiments in which the frame 12 is omitted, the table portion comprises the first component 14 and the second component 16. The table portion has a first end 11 and a second end 13.

[0084] The first component 14 has a first component surface 18 configured to support a body or a body part. The second component 16 is configured to be disposed beneath the first component 14 and to receive any fluid flowing from the first component 14. In this respect, the first component 14 is in fluid communication with the second component 16 through one or more openings 20 defined in the first component surface 18 and / or through one or more of the handle cut outs 15. The second component 16 has a second component surface 22. The second component surface 22 is inclined with respect to the first component surface 18 when the first and second components 14, 16 are assembled so that fluid incident on the second component surface 22 will flow along the second component surface 22. In other words, the first and second component surfaces 18, 22, are not parallel to one another.

[0085] 306683293.1In certain embodiments, the first component surface 18 defines a first plane A and the second component surface defines a second plane B. The first and second component surfaces 18, 22 are planar. When assembled, the second plane B is at an angle to the first plane A. In other words, the first and second planes A, B are not parallel to one another.

[0086] In certain other embodiments, one or both of the first component surface 18 and the second component surface 22 may not be planar. For example, one or both of the first component surface 18 and the second component surface 22 may have a curved portion, such as a concave transverse or longitudinal cross section.

[0087] Regardless of the specific topography of the first component surface 18 and the second component surface 22, when assembled, the second component surface 22 is generally inclined with respect to the first component surface 18 so that fluid incident on the second component surface 22 can flow downwardly. The second component surface 22 is configured to catch fluids flowing from the first component surface 18. The first component surface 18 may be horizontal when the support platform 10 is supported on a horizontal support surface, such as a floor, stretcher or any other support surface.

[0088] The first component surface 18 is sized and shaped to support a body or a body part. The first component surface 18 may have an elongate shape and a respective longitudinal axis. In some embodiments, the first component surface 18 has a rectangular shaped perimeter and is planar. The first component 14 is plate-like meaning that a depth of the first component 14 is less than a width and less than a length of the first component 14.

[0089] As mentioned earlier, the first component 14 has one or more openings 20 extending through the first component surface 18. In some embodiments, the one or more openings 20 are slitlike. In other words, the one or more openings 20 are elongated and extend longitudinally along the length of the first component 14. Fluid on the first component surface 18 will flow through the one or more openings 20 to the second component surface 22. For example, blood that is released during a procedure on the body or body part supported on the first component surface 18 will flow through the one or more openings 20. The one or more openings 20 may have any suitable positioning and size and shape, which may differ from the configuration presented in the figures. In some embodiments, there may be provided a kit of first components 14, each with a different configuration of openings 20 and / or handle cut outs 15. Those with more 306683293.1openings 20 and / or handle cut outs 15 may be useful for procedures in which more abundant fluid release is expected. In this respect, the support platform 10 may comprise a plurality of the first components 14.

[0090] The first component 14 is made of a radiotransparent material, such as, but not limited to, an acrylic plastic. At least a portion of the second component 16 is also radiolucent and made of an acrylic plastic. Other radiolucent materials are within the scope of the present technology. This can allow the body or body part to be imaged, such as by X-ray -based imaging techniques, including computed tomography, whilst supported on the first component surface 18 of the first component 14 while the first component 14 rests on the second component 16. In some embodiments, the frame 12 may also be radiolucent. In yet other embodiments, one or more of the first component 14, the second component 16 and the frame 12 may be radiopaque.

[0091] The second component 16 has peripheral walls 24 extending from and surrounding the second component surface 22. The second component 16 is thus vessel -like or container-like and can retain the fluid therein.

[0092] In some embodiments, one or more support members 35 extend from the second component surface 22, inwardly of the peripheral walls 24. The support member 35 may have any configuration. For example, the support member 35 may comprise one or more pins, or a discontinuous wall, for example.

[0093] In the embodiment of Figures 1-5, the first component 14 is supported by the support member 35 of the second component 16. In other embodiments, the first component 14 is supported by the peripheral walls 24 of the second component 16.

[0094] The second component surface 22 declines between a first end 28 of the second component 16 and a second end 30 of the second component 16. This slope is relative to the support surface (such as a floor or stretcher) when the support platform 10 rests on the support surface. The angled nature of the second component surface 22 helps the fluid to flow towards the second end 30, wherein it can be stored or removed.

[0095] The angle of the second component surface 22 relative to the first support surface is determined by a height difference of the support member 35 between the first and second ends 28, 30. The 306683293.1height of the support member 35 decreases towards the second end 30 of the second component surface 22. A depth 32 of the second component 16 is defined by the height of the support members 35. The depth 32 increases from the first end 28 to the second end 30.

[0096] In some embodiments (not shown), the angle of the second component surface 22 may be adjustable by providing a support member 35 with adjustable height, or by providing replacement support member with a different configuration for adjusting the angle of the second component surface 22. Alternatively, different first components 14 having different configurations of the support member 35 may be provided.

[0097] A top end face 34 of the support member 35 defines a third plane C. The third plane C is parallel with the first plane A and thus different from the second plane B of the second component surface 22.

[0098] In embodiments in which the first component 14 is supported by the peripheral walls 24 of the second component 16, atop end face of the peripheral walls defines the third plane C. In such embodiments, a depth 32 of the second component 16 (best seen in Figure 5) is defined by a height of the peripheral walls 24.

[0099] A drain 26 may be provided, such as at a deepest portion of the second component 16, for draining the fluid away from the support platform 10. The drain 26 may include a pipe or flexible tubing or hose, connected thereto (not shown). The drain 26 may be an opening defined in the second component surface.

[0100] The drain 26 is at the second end 30 of the second component 16. The first end 28 of the second component 16 is at the first end 11 of the table portion. The second end 30 of the second component 16 is at the second end 13 of the table portion. In certain embodiments, there may be provided a drain 26 at each of the first and second ends 28, 30. This may be convenient in embodiments (which will be described later) in which the table portion can be made to tilt towards the first end or the second end 11, 13.

[0101] One or more guide members 36 are provided in the second component 16, such as extending from the second component surface 22 for guiding the flow of fluid from the first end 28 to the

[0102] 306683293.1second end 30. A height of the one or more guide members 36 decreases towards the second end 30. In other embodiments, the one or more guide members 36 may be omitted.

[0103] The frame 12 defines a fourth plane D, which is substantially parallel to the first plane A. When the support platform 10 is disposed on a horizontal support surface, the first, third and fourth planes are also horizontal.

[0104] In some embodiments, the second component 16 and the frame 12 are removably attached together using for example a suitable attachment mechanism. The ability to separate the second component 16 from the frame 12 can permit the first and second components 14, 16 to interface directly with CT scanner tables for imaging purposes, and / or stretcher frames or transport carts for transportation. In embodiments in which the frame 12 is omitted, the attachment mechanism may be provided between the second component 16 and the legs 38.

[0105] Example attachment mechanisms include, but are not limited to, pin-based retention mechanisms (e.g. ball detent pins, quick-release detent pins, spring-loaded locking pins, pushbutton locking pins, clevis pins with retaining clips, T-handle detent pins, indexing pins, captive pins, drop-in alignment pins), latch and over-center mechanisms (e.g. toggle latches, over-center latches, draw latches, compression latches, cam latches, rotary latches, spring-loaded latches, safety latches with secondary retention), threaded and screw-based mechanisms (e.g. thumbscrews, hand knobs, captive threaded knobs, quarter-turn fasteners, cam-lock screws, tool-less threaded fasteners), clamp-based mechanisms (quick clamps, cam clamps, lever-operated clamps, eccentric clamps, over-center clamping arms, toggle clamp assemblies), sliding and interlocking engagement mechanisms (e.g. sliding dovetail interfaces, T-slot engagements, key-and-slot interfaces, interlocking rails, guide rails with end-stop locks), magnetic-assisted mechanisms (e.g. permanent magnets, magnetic catches, or magnetic alignment features), hybrid mechanisms (e.g. pins and latches, clamps and alignment pins, threaded fasteners and secondary safety pins, or magnetic alignment combined with mechanical locking, which could allow separation of alignment, load-bearing, and safetylocking functions).

[0106] Furthermore, the second component 16 may be provided with one or more handles to facilitate handling after disconnection from the frame 12 or the legs 38. The one or more handles may

[0107] 306683293.1comprise handle cutouts, grip profiles, foldable or retractable handles, or integrated carrying handles, to name a few.

[0108] In some embodiments, the support platform 10 further comprises legs 38 attached to the frame 12 which are configured to space the first component surface 18 from the floor. Although illustrated as having four legs, other numbers of legs or other types of mounts are within the scope of the present technology. Each leg 38 has a wheel 40 at a distal end thereof. The wheel 40 may be of a castor type. The wheel 40 may include a brake mechanism. The brake mechanism is configured to prevent a rotation of the wheel.

[0109] The embodiment of the support platform 10 of Figures 6A, 6B, 7, 8 and 9 differ from the embodiments of Figures 1-5 in that the legs 38 have a length that is adjustable enabling a distance of the first component surface 18 from the floor to be adjusted. Each leg 38 has a telescopic configuration permitting the length adjustment. More specifically, each leg 38 has a lower portion 38a and an upper portion 38b. The upper portion 38b may be slidably movable relative to the lower portion 38a. The reverse is also possible with the lower portion 38a being slidable relative to the upper portion 38b. The lower and upper portions 38a, 38b may be configured so that their relative position can be adjusted manually. A hand crank may be provided. In some embodiments, the relative position of the lower and upper portions 38a, 38b may be adjusted by a motor, such as a linear actuator (not shown). Other length adjustment mechanisms are within the scope of the present technology. The length of each leg 38 can be locked by means of any type of locking mechanism such as a pin, a clamp, a screw, etc. In other embodiments, more than two telescoping portions can be provided.

[0110] Furthermore, the embodiment of the support platform 10 of Figures 6A, 6B, 7, 8 and 9 differ from the embodiments of Figures 1-5 in that instead of four legs 38, the support platform 10 is provided with two legs 38, one of the legs 38 being at the first end 11 of the table portion and the other leg 38 being at the second end 13 of the table portion. Each leg 38 has two wheels 40. The two wheels 40 extend from and are spaced laterally by a wheel base 41. As best seen in Figures 8 and 9, one or more rails 42 are attached to the frame 12. In embodiments in which the frame 12 is omitted, the one or more rails 42 may be attached to one or both of the first and second components 14, 16. The rails 42 can be used for ease of handling the support platform 10 and / or for attachment of surgical accessories such as foot rests, arm rests and the like. In other embodiments, the rails 42 may be omitted or may differ in terms of configuration.

[0111] 306683293.1Furthermore, as best seen in Figure 6B, the drain 26 is defined in the second component surface 22 and is disposed closer to the first end 28 than the second end 30 of the second component 16. The second component surface 22 has a profile that declines from the first end 28 towards the drain 26, and from the second end 30 towards the drain 26. It will be appreciated that the drain 26 could be positioned at any position on the second component 16.

[0112] It will be appreciated that the rails 42 of Figures 8 and 9 can be incorporated in the embodiment of the support platform 10 of Figures 1-5. Similarly, the leg 38 and wheel 40 configuration of Figures 6, 7, 8 and 9 can be used in the embodiment of the support platform 10 of Figures 1-5.

[0113] Turning to Figure 10, there is shown an embodiment of the support platform 10 which differs from embodiment of Figures 8 and 9 in that a brace 44 is provided extending between the two legs 38 at the first and second ends 11, 13. The brace 44 can have a stabilizing effect on the support platform 10 by connecting the two legs 38 at their distal ends thereof. The brace 44 can be made of any suitable material and can have any suitable configuration.

[0114] In some examples, the brace 44 has a projected surface area that is substantially the same as that of the first and / or second components 14, 16 (Figure 11 A). In such embodiments, a width of the brace 44 is the same as a width of the first and / or second components 14, 16.

[0115] In the examples of Figures 1 IB, 11C, 1 ID, the width of the brace 44 is narrower than that of the brace 44 of Figure 11 A. In Figure 1 IB, the brace 44 is disposed to a side of the legs 38. In Figure 11C, the brace 44 is disposed centrally between the legs 38. In Figure 11D, the brace 44 comprises a first brace 44a, and a second brace 44b, one on either side of the legs 38.

[0116] The brace 44 may have any suitable cross-sectional profile. For example, a transverse cross-sectional profile of the brace 44 may have a “U” configuration, which is shown in Figure 12. A longitudinal cross-sectional profile may be tapered, as shown in Figure 10, or may have a non-tapered, linear profile (not shown). Any suitable cross-sectional profile, whether transverse or longitudinal, is within the scope of the present technology.

[0117] In certain embodiments, it may be desirable to selectively tilt the first component surface 18 in order to change an orientation of the body or body part supported by the first component surface 306683293.118. Various tilt mechanisms will now be described with reference to Figures 13A, 13B, 13C, 14 and 15; Figures 16A, 16B, 16C; Figures 17A, 17B, 17C; Figures 18A, 18B, 18C and 19; Figures 20 A, 20B, 20C, 21, 22A and 22B; and Figures 23 A, 23B, 23C, 24, and 25. During a tilting operation, one of the legs 38 is caused to be longer than the other of the legs 38. The table portion is caused to move together, i.e. the first and second components 14, 16 with the frame 12. The table portion could be caused to tilt towards the first or second ends 11, 13 so in certain embodiments, there is provided the drain 26 at both of the first or second ends 11, 13.

[0118] With reference to Figures 13A, 13B and 13C, 14 and 15, the support platform 10 substantially corresponds to the support platform 10 of Figures 8 and 9 having extendible legs 38, and further includes three pivots 46 that can accommodate a change in length of one of the legs 38 to create the tilt. The pivots 46 are provided between the frame 12 and the leg 38 at the first and second ends 11, 13 of the table portion, and between the leg 38 and the wheel base 41 at the second end 13 of the table portion. The other leg 38 at the first end 11 of the table portion is fixedly connected to the wheel base 41.

[0119] When the legs 38 at the first and second ends 11, 13 are the same length, the first component surface is horizontal (Figure 13 A). This can be considered as a neutral position. When the leg 38 at the second end 13 has a longer length than the leg 38 at the first end 11, the table portion is inclined towards the first end 11 (Figure 13B). When the leg 38 at the first end 11 is longer than the leg 38 at the second end 13, the table portion is inclined towards the second end 13 (Figure 13C). It will be appreciated that the tilt in the first component surface 18 is thus achieved by extending one of the two legs 38. Various pitches can be obtained by having different relative lengths of each leg 38. In embodiments in which the support platform has more than two legs, the tilt can be achieved in the same manner by introducing a length inequality between the legs 38.

[0120] As mentioned above, two of the pivots 46 are provided at ajunction of the leg 38 and the frame 12. In embodiments in which the frame 12 is omitted, the two pivots 46 can be provided a junction of the leg 38 and the second component 16. The pivot 46 at the leg 38 and the wheel base 41 may be disposed between the wheel 38 and the brace 44, in some embodiments.

[0121] 306683293.1A close-up of the pivot 46 is illustrated in Figure 14 and in this embodiment, the pivot 46 comprises a pin in a cylindrical housing. In other embodiments, the pivot may comprise any other type of pivot such as a shaft on a bearing (such as dry run, ball or roller bearing).

[0122] Referring now to Figure 16A, 16B and 16C, in which the support platform 10 differs from that of Figures 13A, 13B, 13C, 14 and 15 by further including a sliding joint 48 as well as the pivots 46. As before, two pivots 46 are provided between the legs 38 and the frame 12, at the first and second ends 11, 13. The sliding joint 48 comprises a portion of the frame 12 being extendible along a longitudinal axis of the frame 12. The extendible portion may include telescoping parts, for example. A fixed portion of the frame 12 is connected to the second component 16, and the movable portion of the frame 12 is connected to the pivot 46. As before, when the legs 38 at the first and second ends 11, 13 are the same length, the table portion is in a neutral position and the first component surface 18 is horizontal (Figure 16A). When the leg 38 at the second end 13 is extended longer than the leg 38 at the first end 11, the sliding joint 48 permits a change in a length of the frame 12 that is required to maintain the legs 38 parallel to one another (vertical) (Figure 16B). When the leg 38 at the first end 11 is extended longer than the leg 38 at the second end 13, the sliding joint 48 again permits a change in the length of the frame 12 that is required to maintain the legs 38 parallel to one another (vertical) (Figure 16C).

[0123] In the embodiment of Figures 17A, 17B and 17C, the support platform 10 differs from the support platform of Figures 16A, 16B and 16C in that the sliding joint 48 is provided at the connection of the brace 44 with one of the legs 38, such as the leg 38 at the second end 13 as illustrated. By means of the sliding joint 48, when one of the legs 38 is extended to be longer than the other leg 38, the sliding joint 48 permits a length of the brace 44 to be adjusted in order to maintain the legs 38 parallel to one another.

[0124] In the embodiments of figures 13A-13C, 14, 15, 16A-16C and 17A-17C, it will be appreciated that actuation of the length of one or both of the legs 38, causes the pivoting and / or relative sliding. The pivoting and / or sliding can be considered to be a passive consequence of a change in the length of one of the legs 38.

[0125] In any one or more of the above, the sliding joint 48 may be based on a linear guidance mechanism. Examples include: linear rails, linear guideways, profiled rail systems, ballbearing linear guides, plain linear slide assemblies, recirculating linear bearings, and low- 306683293.1friction linear bushings to name a few. These embodiments provide guided translation along a predefined linear path.

[0126] In other embodiments, the sliding joint 48 may have a roller and track based mechanism comprising, for example, track rollers, roller tracks, cam follower tracks, wheel-and-track assemblies, rolling carriage systems, and grooved rail and roller interfaces. Such embodiments convert relative motion into rolling displacement to reduce friction and wear.

[0127] In other embodiments, the sliding joint 48 may have a telescoping structural mechanism comprising, for example, telescoping structural members, including: telescoping beams, nested tubular members, sliding sleeve joints, telescopic box sections, and overlapping beam assemblies with guided translation, to name a few. These embodiments allow relative extension and retraction of structural members while maintaining load-bearing continuity.

[0128] In yet other embodiments, the sliding joint 48 may have a slot-and-pin or guided slot mechanism comprising, for example, slot-and-pin mechanisms, elongated aperture guides, pinned sliding joints, and / or slotted guide interfaces. In these configurations, a pin or follower element engages an elongated slot to permit constrained linear displacement.

[0129] In other embodiments of the sliding joint 48, a sliding interface may be provided to decrease friction between sliding components. The sliding interface may comprise low-friction sliding joints, self-lubricating sliding surfaces, polymeric glide pads, ultra-high molecular weight polyethylene (UHMWPE) or polytetrafluoroethylene (PTFE) sliding interfaces. These embodiments may be particularly suitable for simplified or cost-optimized implementations.

[0130] The sliding joint 48 may additionally or alternatively comprise one or more of: floating supports, compliant sliding mounts, guided floating interfaces, and passive compensation joints.

[0131] The sliding joint 48 is not limited to the embodiments described above and may be implemented using any combination of linear guidance, rolling elements, telescoping structures, slotted guides, or equivalent mechanical arrangements capable of providing passive relative translation in response to angular displacement.

[0132] 306683293.1Furthermore, it will be appreciated that the sliding joint 48 may be disposed at one or both of the first end 11 and the second end 13 of the table portion. A sliding direction may be parallel, inclined, or offset relative to the first component surface 18. The sliding joint 48 may be integrated within a lifting column, beam, or tabletop structure. Structural load may be partially or fully transferred through the sliding joint 48.

[0133] Turning now to Figures 18 A, 18B, 18C and 19, another embodiment of the support platform 10 having a tilting functionality will be described. In the embodiment of Figures 18 A, 18B, 18C and 19, there is provided a parallelogram linkage 50 which can compensate for geometric distance variations induced by angular movement of the table portion by converting such variations into controlled translational motion at one side of the table.

[0134] The parallelogram linkage 50 comprises a pair of vertical beams 52 forming the lateral members of the parallelogram, a top beam 54 rigidly connected to the frame 12, a bottom beam 56 located below the top beam 54, pivots 58 (such as the pivot 46) connecting the beams 52, 54, 56 at their respective ends. The upper portion 38b of the legs 38 are rigidly mounted to the vertical beams 52. In this manner, when the length of the legs 38 is modulated, the first component surface 18 is caused to tilt about a tilt axis whilst the legs 38 stay parallel to one another due to the parallelogram linkage 50 which constrains the vertical beams 52 to remain substantially parallel, and a relative longitudinal displacement is generated at one side of the support platform 10.

[0135] This longitudinal displacement is accommodated by passive translational motion of the corresponding legs 38 relative to the floor.

[0136] It will be appreciated that any one or more of the vertical beams 52, top beam 54 and bottom beam 56 may have any suitable size and aspect ratio configuration. Any one or more of the vertical beams 52, top beam 54 and bottom beam 56 may be partially or fully integrated with any of the components of the support platform 10 such as the frame 12, the first component 14 or the second component 16.

[0137] Wheels 40 on the first end 11 of the table portion are able to pivot and lock, thereby defining a fixed reference in both rotation and translation. The wheels 40 on the second end 13 of the support platform 10 are configured to remain free to roll and are constrained to roll along a 306683293.1direction substantially parallel to a longitudinal axis of the support platform 10. In this way, changes in the effective distance between the legs 38 during tilting of the first component 14 are absorbed by passive rolling translation of the second end 13, rather than by structural deformation. In other embodiments, the translational motion may occur at one or both ends 11, 13 of the table portion.

[0138] In some embodiments, the support table 10 may further include one or more sliding joints 48.

[0139] In this embodiment, the parallelogram linkage 50 can maintain parallel alignment of the legs 38 throughout the full tilt range, side loads and bending moments on the legs can be reduced and / or minimised. By converting geometric mismatch into passive floor-level translation, it can eliminate the need for active control or powered sliding mechanisms at the level of the first and / or second components 14, 16.

[0140] Turning now to Figures 20A, 20B, 20C, 21, 22A and 22B, in another embodiment of the support platform 10 with a tilt functionality, the support platform 10 is provided with a rolling base 60 at the distal end of each leg 38. The rolling base 60 is configured to be self-aligning and to provide passive angular alignment and translational support during tilting of the first component 14. This can enable the leg 38 to rotate freely about its vertical axis, thereby accommodating changes in orientation induced by the tilt without imposing lateral constraint or inducing structural stress.

[0141] The rolling base 60 comprises a base plate 62 rigidly connected to the distal end of the leg 38, and a plurality of wheels 40 extending from the base plate 62. There may be three wheels 40 or four wheels 40. The wheels 40 are distributed about the base plate 62 so as to provide static stability and load-bearing support. The base plate 62 may have any suitable shape. In certain embodiments, the base plate 62 has a polygonal or tapered geometry which can provide a stable footprint whilst minimising a footprint to provide as much space under the support platform 10 as possible.

[0142] The rolling base 60 is mechanically coupled to the leg 38 such that: the rotational motion of the rolling base 60 occurs passively, without requiring active control using for example a motor or an actuator. The rolling base is configured to self-orient in response to translational forces generated during the tilting.

[0143] 306683293.1In some embodiments, the wheels 40 of one of the rolling bases 60 are not lockable whilst the wheels 40 of the other of the rolling bases 60 are lockable. This rotational degree of freedom allows the rolling base 60 to align with a direction of motion imposed by the kinematics during tilt.

[0144] In use, when the length of one of the legs 38 is modulated to induce the tilt to the first component 14, relative longitudinal translation is induced at one end 11, 13 of the table portion. The self-aligning rolling base 60 translates along the floor to accommodate the induced displacement. As a result, translational motion is absorbed at floor level rather than through deformation or constraint within the support platform 10.

[0145] As such, side loads and torsional stresses applied to the legs 38 may be reduced and / or minimised. This can enable a smooth passive compensation during tilt motion without loss of stability.

[0146] It will be appreciated that the rolling base 60 may have any suitable structure permitting passive rotation about a vertical axis of the leg 38 and to accommodate translational motion induced by angular movement of the first component 14. For example, the rolling base 60 may include any number of wheels 40; the wheels may be of any suitable type, size, or spacing; the base plate 62 may have any suitable geometry. In some embodiments, the rolling base 60 has at least three wheels 40 which are casters. The wheels 40 may be arranged as a two-dimensional array, such as in a triangular configuration. The rolling base 60 may be integrated partially or fully with the leg 38. The rolling base 60 may further include optional locking features, braking mechanisms, or directional constraints without departing from the core self-aligning function.

[0147] The rolling base 60 may be combined with any of the embodiments described herein which include passive sliding mechanisms, such as the parallelogram linkage embodiment of Figures 18 A, 18B, 18C and 19. The rolling base 60 may function as the sole translational compensation mechanism at the first end 11 and / or the second end 13 of the table portion. It will be appreciated that the movement of the rolling base 60 is independent of individual wheel pivoting and does not require individual wheel steering.

[0148] 306683293.1Turning now to Figures 23 A, 23B and 23C, another embodiment of the support platform 10 is illustrated in which the first component 14 has a tilt functionality. In the embodiment of Figures 23 A, 23B and 23C, there is provided a winch mechanism 64 operatively connected to one of the first end 11 and the second end 13 of the table portion and a motorized lifting column 66 at the other of the first end 11 and the second end 13 of the table portion. The lifting column 66 may comprise the extendible leg 38 comprising the tower and upper portions 38a, 38b. The lifting column 66 and the winch mechanism 64 operate in a coordinated manner to control a height of the first and second components 14, 16 and a tilt of the first component 14. Tilt and height adjustment can be achieved through combined vertical actuation of the lifting column 66 and controlled length adjustment of a tension member driven by the winch mechanism 64. The winch mechanism 64 may have any suitable configuration such as having a structural mast 68 connected to the frame 12 and a tension member 70 extending between the winch mechanism 64 and the support platform 10.

[0149] To tilt the table portion so that the first component surface 18 slopes towards the first end 11 of the table portion, the winching mechanism 64 is caused to reel in the tension member 70. To tilt the first component 14 so that the first component surface 18 stopes towards the second end 13 of the support platform 10, the winching mechanism 64 is caused to pay out the tension member 70.

[0150] It will be appreciated that an overall height of the first component surface 18 may be adjusted by synchronous operation of the lifting column 66 and the winch mechanism 64. In this manner, an independent or combined control of height and tilt of the first component surface 18 can be obtained using a single lifting column 66 and a winch mechanism 64. A structural complexity is reduced compared to at least some of the earlier described embodiments with a tilt function.

[0151] The winch mechanism 64 may comprise a manual or a motorized mechanism and can be of any type such as, but not limited to, constant-tension winches, spring-assisted winches, selflocking winches, or multiple tension members acting on one or more attachment points. Any table adjustment system in which a height and tilt are controlled through coordinated operation of a lifting column and a tension-based winch mechanism which is considered functionally equivalent to the embodiment described herein, is included within the scope of the present technology.

[0152] 306683293.1In the embodiment of the support platform 10 shown in Figure 24, the lifting column 66 has been replaced by a winch and linear motion system 72 configured to provide an equivalent functional role. Such substitution may not alter the overall kinematic intent of the system. The winch and linear motion system 72 may be considered functionally equivalent to a lifting column in that it is capable of: contributing to vertical positioning of the first component 14 or a portion thereof contributing to angular (tilt) adjustment of the first component 14, and accommodating geometric angular variation induced by tilt.

[0153] Equally, any of the extendible legs 38 shown in all embodiments described herein, may be replaced by such a winch and linear motion system 72.

[0154] The mechanisms, architectures, and embodiments described herein for pitch (tilt about a transverse axis) are also generally applicable by transposition to roll (tilt about a longitudinal axis) by applying the same concepts across the width of the table portion of the support platform 10 rather than along its length. Unless explicitly stated otherwise, any embodiment described for pitch adjustment may be adapted to roll adjustment through a corresponding rearrangement of structural elements.

[0155] In roll-based embodiments, components previously arranged along the longitudinal direction of the support platform 10 may instead be arranged along the transverse direction. Lifting columns, structural supports, sliding mechanisms, winches, or compensation systems may be positioned symmetrically or asymmetrically across the support platform 10 width, and geometric distance variations induced by roll are accommodated using the same functional principles described for pitch.

[0156] To enable combined pitch and roll motion, passive pivot joints described in pitch-only embodiments may be replaced with multiaxis joints, including but not limited to: ball joints, spherical bearings, universal joints, or equivalent articulated joints permitting rotation about multiple axes. Such joint substitution may allow the first component to rotate about both longitudinal and transverse axes while preserving the functional intent of the underlying embodiment.

[0157] In combined pitch-and-roll configurations, pitch and roll adjustments may be controlled independently or in a coordinated manner. Actuation mechanisms (lifting columns, winches, 306683293.1linear motion systems) may be duplicated, paired, or cross-coupled across both axes, and passive compensation mechanisms (sliding joints, rolling bases, tension members) may operate simultaneously in multiple directions.

[0158] In certain embodiments, combined pitch-and-roll adjustment may be achieved through reorientation and combination of mechanisms described for pitch or roll individually. In other embodiments, combined pitch-and-roll adjustment may employ dedicated mechanisms specifically configured to provide multi-axis angular motion.

[0159] Referring now to Figures 25 and 26, in certain embodiments, the support platform 10 is configured to have a two-axis angular adjustment of the first component surface 18, namely: tilt (e.g., Trendelenburg / reverse Trendelenburg, or pitch about a transverse axis), and roll (lateral roll about a longitudinal axis).

[0160] In certain embodiments, the support platform 10 is provided with at least one lifting column 74 connected to the table portion of the support platform 10 (i.e. one or more of the frame 12, the first component 14, the second component 16) by a ball joint 76 and at least two linear actuators 78 arranged to define adjustable support points. The ball joint 76 provides multi-axis angular freedom at an interface of the lifting column 74 and the table portion, allowing the frame 12, first and second components 14, 16 to rotate while the lifting column 74 provides a primary vertical support reaction.

[0161] The linear actuators 78 may comprise, for example, electric screw actuators (lead screw / ball screw), electromechanical linear actuators, hydraulic or pneumatic linear actuators, or any other actuator capable of controllably varying an effective length of the legs 38.

[0162] In a two-actuator configuration, the table portion of the support platform 10 is supported at three points: a primary support point at the lifting column 74 and ball joint 76, and two additional support points provided by the two linear actuators 78. By extending / retracting the two actuators 78 differentially, roll of the table portion is achieved via left-right differential stroke, and tilt is achieved via coordinated stroke changes relative to the ball-joint support point (depending on geometry).

[0163] 306683293.1The two actuators 78 may be positioned: at opposite lateral sides of the table portion, near the first end 11 and / or the second end 13, symmetrically about a longitudinal centerline, or in any arrangement providing sufficient moment for pitch and roll.

[0164] In a three-actuator configuration, the table portion may be supported by: the lifting column 74 via the ball joint 76, and three linear actuators 78 disposed for example in a triangular pattern or any equivalent polygonal distribution.

[0165] This configuration, compared to the two actuator embodiment, may provide improved stiffness, improved load distribution, increased control authority for combined tilt / roll, and / or redundancy or finer leveling control.

[0166] In some embodiments, the ball joint 76 may be configured as one or more of: a spherical bearing, a rod-end spherical bearing a ball-and-socket joint, universal joint (Cardan joint), gimbal joint, a compliant joint (elastomeric or flexure-based) providing equivalent angular freedom. Optionally, the ball joint may include: angular travel limits, preload / damping, and / or a sealed / cleanable housing.

[0167] The actuators may be modulated in a coordinated manner to achieve predefined target table portion orientations. The modulation may include: open-loop control, closed-loop control using position sensors (e.g., encoders, potentiometers), and / or feedback from an inertial sensor (e.g., IMU) or angle sensor.

[0168] Tilt and roll may be achieved using any combination of: one or more lifting columns coupled via a multi-axis joint, and two or more linear actuators defining controllable support points, wherein differential actuator extension produces at least two rotational degrees of freedom of the table portion.

[0169] In certain embodiments, the lifting column may be located near an edge or near a comer of the table portion. The linear actuators may connect to at least one of the frame 12, the first component and the second component 16 of the table portion directly or via an intermediate subframe / carriage. The support platform 10 may include passive sliding (previous section) to accommodate geometry changes during tilt / roll.

[0170] 306683293.1Advantageously, the inclined second component surface 22 permits any fluid flowing through the openings 20 into the second component 16 to collect at one end thereof. This can provide ease of removal of the fluid and subsequent clean up. This is clearly advantageous from a health and safety perspective, especially when the fluid is a bodily fluid, such as blood, or embalming fluids or perfusion fluids. Advantageously, by means of the radiolucent nature of the first and second components 14, 16 in some embodiments, the body or body part supported on the first component surface 18 can be medically imaged using for example x-rays or CT scans whilst supported on the support platform 10, obviating the need to move the body or body part.

[0171] Modifications and improvements to the above-described embodiments of the present technology may become apparent to those skilled in the art. The foregoing description is intended to be exemplary rather than limiting. The scope of the present technology is therefore intended to be limited solely by the scope of the appended claims.
