[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Patent Application No. 15 / 610,486, filed May 31, 2017, the subject matter of which is incorporated by reference in its entirety. [Background technology]

[0002] Patient support devices, such as operating tables, examination tables, hospital beds, and the like, are well known. The devices are expected to support the patient's weight before, during, and after a medical procedure while allowing the medical team unobstructed access to the surgical site and the ability to move, position, or reposition the patient. Certain prior art devices are capable of detecting changes in weight distribution, which helps the medical team properly position or reposition the patient and prevent unwanted or inadvertent movement of the patient.

[0003] For example, U.S. Patent No. 7,784,126 discloses a surgical table having a support column and a table panel attached to the support column. The table has a force measurement system for measuring the weight of the table panel and the patient on the table panel. The weight measurement is used to prevent the table from tipping over.

[0004] U.S. Patent Application Publication No. 2012 / 047655 discloses a patient bed having a base, an upper frame on the base, and an elevation system for raising and lowering the upper frame relative to the base between a low position and a high position. The bed can include a scale system coupled to or included as part of a control circuit. The scale system detects a weight supported by the upper frame. A threshold angle, i.e., an angle at which an adverse event such as a tipping event may occur, can be adjusted based on the weight detected by the scale system.

[0005] No. 7,610,637 discloses a patient support having various weight sensors for determining the patient's weight, and a user interface is provided that indicates the addition or subtraction of medical equipment, such as an IV pole, to the patient support so that the weight of the medical equipment can be taken into account.

[0006] U.S. Patent No. 7,255,366 discloses a system for monitoring the weight of a patient on a patient support and detecting patient movement, such as attempts to exit the support. Load cells are used to monitor the weight on various portions of the support. A control system modifies the measurements based on the position or configuration of the support.

[0007] U.S. Patent No. 5,628,078 discloses a surgical table having several removable sections that allow for a variety of possible configurations. Sensors detect the table configuration and send appropriate signals to a controller. Each of the above patents and publications is incorporated herein by reference in its entirety.

[0008] These and other prior art devices have several limitations. For example, with at least some prior art devices, accurate measurement of changes in weight distribution can be difficult to achieve. Some prior art devices are difficult or cumbersome to operate. The Steris® 5085 SRT operating table has fixed handles at the head or foot, which, in certain situations, unnecessarily increases the overall length of the table. Certain prior art tables are not particularly stable and can be expensive to manufacture. For example, many prior art operating tables utilize vertical hydraulic columns with telescoping blocks to raise and lower the patient support platform. These tables, especially when designed to move downward near the ground, are expensive to manufacture and contain oil in the hydraulic system that can inadvertently leak. Summary of the Invention

[0009] In one embodiment, the disclosed technology is directed to a system for supporting or positioning a patient before, during, or after a medical procedure. The system includes a platform configured to support at least a portion of a patient. A support column is disposed below the platform. A base is disposed below the support column and configured to support the support column. The base includes at least one drive wheel configured to contact a ground surface and assist a user in moving the platform relative to the ground surface. A drive-assist user interface module is operably connected to the at least one drive wheel. The drive-assist user interface module is configured to allow an operator of the system to selectively control movement of the at least one drive wheel. The drive-assist user interface module forms part of or is attached to an attachment including a plate having an upper surface. In one configuration or position, the upper surface of the attachment plate is configured to be flush with or extend parallel to an upper surface of the platform when the attachment is attached to the platform. In one or more other configurations and positions, the upper surface of the plate of the attachment is configured to extend at an angle relative to the upper surface of the platform when the attachment is attached to the platform.

[0010] In another embodiment, the disclosed technology is directed to a system for supporting or positioning a patient before, during, or after a medical procedure. The system may include a platform configured to support at least a portion of a patient. A support column is disposed below the platform. At least a portion of the support column (e.g., its cover) encloses a support and lifting mechanism configured to support and elevate the platform. The support and lifting mechanism includes a first linkage system and a second linkage system. The first linkage system includes at least one upper four-bar linkage and at least one lower four-bar linkage. The second linkage system includes at least two link bars connected in series and configured to move in a plane perpendicular to the first linkage system. A base is disposed below the support column and configured to support the support column. The base includes at least one drive wheel configured to contact the ground and move the platform relative to the ground.

[0011] In yet another embodiment, the disclosed technology is directed to a system for supporting or positioning a patient before, during, or after a medical procedure. The system includes a platform configured to support at least a portion of a patient. A support column is disposed below the platform. A base is disposed below the support column and configured to support the support column. The base includes at least three spaced apart casters, each configured to contact a ground surface and enable movement of the platform relative to the ground surface. The base also includes at least one drive wheel configured to contact the ground surface and enable movement of the platform relative to the ground surface. The base further includes at least three load detection / floor-lifting mechanisms configured to contact the ground surface and prevent inadvertent movement of the platform relative to the ground surface. Each of the at least three load detection / floor-lifting mechanisms includes a support foot and a motor. The motor is configured to raise the support foot so that the caster wheel contacts the ground surface. The motor is also configured to lower the support feet and raise the platform at least slightly to prevent one or more of the caster wheels from contacting the ground.

[0043] While systems, devices, and methods are described herein as examples and embodiments, those skilled in the art will recognize that the systems, devices, and methods of the presently disclosed technology are not limited to the described embodiments or drawings. It should be understood that the drawings and description are not intended to be limited to the particular forms disclosed. Rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the appended claims. All headings used herein are for organizational purposes only and are not intended to limit the scope of the description or claims. As used herein, the terms "is" and "can" are used in an permissive (i.e., possible) sense rather than a required (i.e., must) sense. Similarly, the word "comprises" means to include, but is not limited to. Unless otherwise specified herein, the singular terms "a," "an," and "the" should be read as meaning "at least one" rather than limited to one element. The term "actuator" is broadly defined herein to mean any component capable of at least initiating movement or control of a mechanism, part, or system, and includes triggers, buttons, switches, or other enabling devices. The terminology includes the above words, derivatives thereof and words of similar import.

[0044] Referring in detail to the drawings, wherein like numerals refer to like elements throughout, the presently disclosed technology relates to at least partially modular, multi-component systems, devices, and methods that enable surgeons and / or medical teams to better monitor, support, position, reposition, and / or manipulate a patient before, during, and / or after surgery by electrical and / or mechanical means. The presently disclosed technology allows the surgeon and / or medical team to support the patient vertically above the floor or ground, allowing the surgeon and / or medical team to more quickly and easily move or position the patient, and / or provide other functions. The term "patient" is defined broadly herein to include human patients of all sizes, genders, and demographics, as well as animals (e.g., for veterinary purposes). The system or apparatus (generally designated 100) may be referred to herein as a surgical table. The surgical table may be any of a variety of types or styles and may vary in size, shape, and / or configuration from those shown and described herein.

[0045] FIG. 1 illustrates one embodiment of a surgical table 100 of the disclosed technology. The surgical table 100 may include an upper platform 102, a lower base 400, a support column 300 therebetween, and a table support or first attachment 500. The surgical table 100 may also include additional attachments or modules, such as, but not limited to, a second attachment 800 and a third attachment 900. In one aspect, the attachments 500, 800, and 900 serve to extend the length of the surgical table 100, thereby allowing the surgical table 100 to fully support patients of different sizes and lengths. The patient may rest or lie directly on the platform 102 (which may extend at least partially onto the attachment 500 or one or more other attachments), and at least a portion of the base 400 may contact the floor or ground 104. The posts 300 are selectively adjustable, as described in detail below, allowing the surgeon and / or surgical team to adjust the position of the platform 102 relative to the base 400.

[0046] As described in further detail below, the operating table 100 can include a drive assist assembly that can include a drive assist mechanism 700 and a drive assist user interface module 508. The mechanism 700 can be present on the base 400, and the module 508 can be present on or connected to either end of one or more attachments to the upper platform 102. The mechanism 700 can include at least one drive wheel 600, and the mechanism 700 can be configured to move or pivot the at least one drive wheel 600 between a stowed position and a use position to engage and disengage with the ground surface 104. The module 508, in combination with one or more other components or parts of the operating table 100, can assist a surgeon or medical team in positioning the operating table 100, controlling various functions of the operating table 100, and / or quickly and efficiently positioning, repositioning, or moving the operating table 100.

[0047] 1-13, one or more embodiments of the support column 300 may include a support and lifting mechanism, generally designated 302, having a first linkage system 304 and a separate second linkage system 306 (see FIG. 2). The two linkage systems 304, 306 may be connected or attached at one, two, or more points and complement each other to efficiently, stably, and / or compactly raise and / or lower the platform 102. As will be apparent from the structures described below, at least the first linkage system 304 (alone or in combination with the second linkage system 306) may provide resistance to moments of the operating table 100 about roll or tilt (i.e., the x-axis), pitch or Trendelenburg (i.e., the y-axis), and yaw or table twist about a vertical axis (i.e., the z-axis), and / or resistance to lateral forces. When the first and second linkage systems 304, 306 are mounted on a vertical surface, the combination also provides resistance to longitudinal forces.

[0048] First linkage system 304 may include at least one or two spaced-apart, parallel sets 308a, 308b of upper four-bar linkages connected by axles and supported on bearings, such as tapered roller bearings, ball bearings, or bushings. One set 308a of upper four-bar linkages may be on the left side of mechanism 302, and the other set 308b of upper four-bar linkages may be on the right side of mechanism 302. First linkage system 304 may also include at least one or two spaced-apart, parallel sets 310a, 310b of lower four-bar linkages connected by axles and supported on tapered roller bearings. One set 310a of lower four-bar linkages may be on the left side of mechanism 302, and the other set 310b of lower four-bar linkages may be on the right side of mechanism 302. Overall, in one embodiment, first linkage system 304 may include four four-bar linkages. Those skilled in the art will appreciate that a four-bar linkage is considered the simplest movable closed chain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints, generally arranged so that the links move in parallel planes.

[0049] The upper and lower four-bar linkage sets 308a, 308b, 310a, 310b can be arranged in series with one another and joined or connected by a common element, such as a “floating” or movable torque reactor 312. An upper torque reactor 314, which can form part of each of the upper four-bar linkages, can connect the remainder of the upper four-bar linkage to a Trendelenburg axis mount 316 and a Trendelenburg actuator mount 318. In one embodiment, the upper torque reactor 314 can support and / or enclose a printed circuit board (PCB) 315 (see FIGS. 10 and 12 ), thereby allowing the surgeon and / or medical team to move or reposition the operating table 100 and / or mechanism 302. At least one or two spaced-apart lower support mounts 320a, 320b, which can form part of each of the lower four-bar linkages, can connect the remainder of the lower four-bar linkage to the base 400 (directly or indirectly).

[0050] In one embodiment, lower four-bar linkage sets 310a, 310b can be spaced at least slightly outward from upper four-bar linkage sets 308a, 308b. As a result, at least a portion of upper four-bar linkage sets 308a, 308b can be disposed between at least a portion of lower four-bar linkage sets 310a, 310b. This configuration allows mechanism 302 to have a generally compact configuration when in a folded or compressed state (see FIGS. 10-13).

[0051] The second linkage system 306 (e.g., cross-link) may be formed from two, three, or more link bars 330a, 330b, 330c connected in series and a lower support block 332 attached (directly or indirectly) to the base 400 via any of a variety of means (screws, bolts, welding, etc.). The link bars 330a, 330b, 330c of the second linkage system 306 may be hinged or otherwise arranged to pivot so that the axis of each link bar 330a, 330b, 330c extends perpendicular to the axis of the upper and lower four-bar linkages. The second linkage system 306 may be positioned relative to the first linkage system 304 so that the mechanism has a generally compact configuration when in a collapsed or compressed state (see Figures 10-13). This compact configuration allows the upper platform 102 to move downward closer to the ground 104 than prior art equipment.

[0052] In operation of one embodiment of the disclosed technology, the movement of the four-bar linkage can be limited to movement only in the x and z planes (i.e., no movement in the y plane). The movement of the link bars 330a, 330b, 330c can be limited to movement only in the y and z planes (i.e., no movement in the x plane). The first and second linkage systems 304, 306 can be connected to each other at or by the upper torque reactor 314 and / or at or by the base 400. In one embodiment, when combined, the only movement permitted by the first and second linkage systems 304, 306 is in the z axis (e.g., up and down). Thus, when combined, the first and second linkage systems can resist all movement except for raising and lowering the upper platform 102.

[0053] Vertical lifting or upward force to or relative to the upper platform 102 may be provided by a lifting mechanism 350, such as a lead screw or piston, and / or an actuator or motor 352 operably connected thereto. The lifting mechanism 350 may be concentric and / or telescoping, and may be a threaded rod and nut, a ball screw, or a roller screw. In one embodiment, a concentric design with dual parallel threads may be used. In another embodiment, dual concentric screws (i.e., four screws total) may be used, which may be less expensive. In yet another embodiment, the lifting mechanism 350 may be a push chain that can be hinged to bend in one direction but limited to bend in the other direction.

[0054] The lifting mechanism 350 can be disposed within or surrounded by the first and second linkage systems 304, 306. Thus, as the lifting mechanism 350 extends or collapses (e.g., through rotation of a portion thereof), the first and second linkage systems 304, 306 can expand or contract around the lifting mechanism 350 to create an efficient, compact structure. In one embodiment, the lifting mechanism 350 and / or actuators 352 provide all of the lifting force to the upper platform 102, while the first and second lineage systems 304, 306 help reduce moment loads and / or increase lateral stiffness or stability of the operating table 100.

[0055] 14A-15 illustrate an embodiment of a table platform or first attachment 500 with one or more other components of the system. The first attachment 500 can be in the form of a head platform configured to be removably attached to at least a portion of the upper platform 102. The first attachment 500 can be configured to support at least a portion of the patient's head and / or upper body during surgery. As described above, the system can also include one or more other platforms or attachments, each removably attachable to one another and / or the upper platform 102, and configured or designed to support other portions of the patient (e.g., the lower body or lower limbs) during surgery. In one embodiment, the first attachment 500, the second attachment 800, and the third attachment 900 can each be any patient support designed to be removably attached to the remainder of the operating table. For example, as described above, the first attachment 500 can be in the form of a removable head support. The second attachment 800 may be in the form of a removable back support and the third attachment 900 may be in the form of a removable leg or lower body support.

[0056] 14A-14D illustrate a first attachment 500 having a drive-assist user interface module 508 that can provide an operator with the ability to quickly, easily, and / or efficiently move, maneuver, position, and / or reposition the operating table 100, as described in detail below. Depending on its location and configuration, the combination of the drive-assist user interface module 508 and the first attachment 500 can also provide the operator with increased comfort or a better "feel" for moving the operating table 100. In one embodiment, the user interface module 508 can include one or more actuators that provide the ability to selectively steer and / or adjust (e.g., via a motor) the speed of at least one drive wheel 600 of the operating table 100. For example, the interface module 508 can be configured to control the linear speed (e.g., very slow (creep), medium, and fast) of the operating table 100 relative to the ground surface 104 and / or the direction of movement (e.g., forward or reverse) of the operating table 100. The positioning of the combination of the drive-assist user interface module 508 and the first attachment 500 relative to the rest of the operating table 100, the ergonomics of that combination, and the functionality of the drive-assist user interface module 508 provide the operator with more control than is provided by prior art devices.

[0057] As described in more detail below, the drive-assist user interface module 508, or one or more portions thereof, allows an operator (e.g., a surgeon or any member of the medical team) to control the movement of the operating table 100 with both hands, ensuring a firm grip on the first attachment 500 and / or the operating table 100 at all times. With certain prior art tables, one hand of the operator is required to grasp a separate hand pendant or proprietary module next to or on top of the table. In contrast, the drive-assist user interface module 508 of the disclosed technology can reside on or with the operating table 100, so that the operator does not need to locate and install an accessory, but can be stored or attached in a manner that has minimal or beneficial effect on the use of the operating table 100.

[0058] The first attachment 500 can include or be attached to a drive-assist user interface module 508 and can be formed of any lightweight, high-strength material, such as a durable plastic like glass-filled nylon. The first attachment 500 can include a plate 502 supported by at least one or two spaced-apart, parallel arms 504a, 504b and a rail or crossbeam 506 connecting the two ends of the arms 504a, 504b. The plate 502 can include a top surface 502a and an opposing bottom surface 502b. When the first attachment 500 is properly attached to the rest of the operating table 100, the plate 502 can be approximately flush with the upper platform 102. Each arm 504a, 504b can include a side rail 505a, 505b attached thereto and spaced at least slightly outward therefrom. For clarity, the side rails 505a, 505b, as well as certain other components of the disclosed technology, have been omitted from Figures 14C and 14D.

[0059] In one embodiment, the drive-assist user interface module 508 can be pivotally and / or removably mounted to at least a portion of the cross beam 506. In another embodiment, the module 508 can be mounted to the arms 504a, 504b via one or more brackets or pivot points 520 (see FIGS. 14B and 14C ) such that the module 508 is pivotable about an axis extending parallel to the cross beam 506. Regardless of how it is mounted to the first attachment, the user interface module 508 can include the electronics, power source (e.g., battery), actuators or buttons, latch magnets, and / or connectors necessary to achieve the functionality described herein.

[0060] In one embodiment, the module 508 may be movable between a downward or stowed (e.g., non-use) position (see FIG. 14C ) and an upward or use position (see FIGS. 14A and 14B ). In the deployed or use position, at least a portion of the module 508 may encase and / or cover at least a portion of the cross beam 506. FIG. 14D shows the module 508 in a position between the stowed and deployed positions. An electrical connector 509 may extend outward from the module 508 and may be electrically connected to the rest of the operating table 100 by a cable or wire (not shown). The connector 509 may thus be configured to power one or more batteries and enable communication with the module 508 during initialization. However, during use of one embodiment of the operating table 100, the cable and connector 509 are detached from the operating table 100. In one embodiment, when the cable and connector 509 are attached to the operating table 100, the first attachment 500 may communicate without using wireless technology. This is useful if the battery (described in more detail below) in module 508 runs out of power before or during an intended movement of operating table 100.

[0061] The module 508 may include one or more spaced apart connecting mechanisms 524 (see FIG. 14D), such as magnets, mechanical latches, or detents integrated into one or more components. Similarly, the connecting mechanisms 524 or other connecting mechanisms may be designed and / or configured to hold or otherwise support the module 508 in a stowed position.

[0062] A control embedded in, attached to, or mounted on the module 508 and / or one or more actuators of the module 508 can be configured to sense the presence of one or more attachment mechanisms 524 (e.g., magnets) to create an automatic on / off switch. When the module 508 is deployed and an attachment mechanism 524 is detected, the capacitive enable switch and wireless functionality can be activated (e.g., draw power and go to an "on" state). When the module 508 is in a stowed position (e.g., no magnets 524 are detected), power can be reduced or turned off. This serves as both a safety feature and a power-saving feature.

[0063] Additionally, the above controls allow an operator of the operating table 100 to selectively adjust the speed and / or direction of table transport. For example, a capacitance switch or sensor 510 may be located on or mounted on the module 508, separate from or embedded within a printed circuit board (PCB) 511 (shown schematically in FIG. 14D). As will be appreciated by those skilled in the art, capacitive switches such as sensor 510 do not require physical actuation, only physical proximity.

[0064] In one embodiment, the palm grip 512 of the module 508 (referred to herein for convenience simply as the “first actuator”) can align with and / or complement the switch 510 when the module 508 is properly attached to and / or positioned relative to the cross beam 506. Engagement of the palm grip 512 by an operator (e.g., with the palm of a hand) (hereinafter, “engagement” may mean grasping when the operator grasps the palm grip 512) can activate the switch 510, thereby activating one or more movement control buttons (described in more detail below). In one embodiment, such engagement / actuation alone does not move the operating table 100 or actuate the drive wheels 600. Instead, in such an embodiment, such engagement / actuation can enable the operator to move the operating table 100 and / or actuate the drive wheels 600 via a second or additional step (e.g., engagement of a separate actuator).

[0065] In one embodiment, this provides a level of safety not available with a pendant command table. For example, at least a portion of the operator's fingers must extend through hole 518 in order to place the palm of the operator's hand on palm grip 512, ideally grasping at least a portion of first attachment 500 and thereby controlling operating table 100. In certain embodiments, operating table 100 weighs approximately 900 pounds by itself and can weigh approximately 1500 pounds with a patient attached.

[0066] 14, the module 508 may include one or more movement control buttons, such as a second actuator 514, a third actuator 516, and a fourth actuator 517. All of the actuators 512, 514, 516, and 517 may be spaced apart from one another. In one embodiment, the actuators 512, 514, 516, and 517 may be positioned such that at least a portion of one hand of an operator's palm can engage the first actuator 512, while at least a portion of the operator's thumb can easily engage either the second actuator 514, the third actuator 516, or the fourth actuator 517. The size, shape, and / or location of each of the actuators 512, 514, 516, and 517 are not limited to those shown in FIG. 14 and described herein. For example, instead of all of the actuators 512, 514, 516, 517 being located on the right portion of the module 508, one or more of the actuators 512, 514, 516, 517 can be located on the left portion of the module 508. The second actuator 514 and the third actuator 516 can be momentary switches configured to initiate or control forward and reverse movement, respectively, of the operating table 100 and / or the drive wheels 600. The fourth actuator 517 can be a momentary switch configured to initiate a "fast forward" movement of the operating table 100 and / or the drive wheels 600.

[0067] In one embodiment, movement of the operating table 100 and / or drive wheel 600 stops when the palm grip 512 or any of the second actuator 514, third actuator 516, or fourth actuator 517 are not engaged, contacting, or pressing. In other words, if the operator "let go" of the module 508 such that the first actuator 512 is not engaged or any of the second actuator 514, third actuator 516, and fourth actuator 517 are not engaged, the operating table 100 and / or drive wheel 600 brakes or stops. This configuration prevents unwanted or unintended movement of the operating table 100 and / or drive wheel 600 unless the operator holds the module 508 tightly with the first actuator 512 and engages one of the second actuator 514, third actuator 516, or fourth actuator 517.

[0068] When not in use (e.g., when the operating table 100 is desired to remain in one location for an extended period of time), the module 508 can be folded downward or rotated relative to the rest of the first attachment 500. Alternatively, in one embodiment, the module 508 can be separated from the rest of the first attachment 500. In one embodiment, when an operator wishes to move the module 508 from the stowed position (FIG. 14C) to the deployed position (FIG. 14A), the operator can insert at least a portion of the operator's hand through one or more spaced openings or cutouts 518 (i) in the plate 502 or (ii) between the plate 502 and the cross beam 506 to flip or rotate the module 508 about one or more brackets or pivot points 520 (see FIGS. 14B and 14C). The module 508 can be moved between the stowed and deployed configurations in a matter of seconds, and does not significantly extend the overall length of the operating table 100 in either configuration.

[0069] In one embodiment, the first attachment 500 and / or any of the other attachments can interface with and / or communicate with a separate hand pendant and / or auxiliary panel of the operating table 100. For example, radio frequency (RF) communication, such as the ZigBee standard, can be used to communicate between the hand pendant, the first attachment 500, and / or the auxiliary panel. In one embodiment, the module 508 and / or the first attachment 500 can include an embedded wireless interface printed circuit assembly (PCA), which can communicate with other separate PCAs within the operating table 100 while operations are being commanded by the operator. This technology allows the hand pendant to provide an indication to the operator of the status of the drive assist mechanism 700 (deployed, enabled, active forward, active reverse, etc.) and / or the battery charge status of the first attachment 500. In one embodiment, the drive assist wheels 600 are not controlled via the hand pendant; only the module 508 and / or the first attachment 500 can control the drive wheels 600. However, the techniques of this disclosure are not limited to such an arrangement or configuration.

[0070] When not deployed (e.g., when the magnet 524 is not detecting contact with the end rail 506), no power is consumed by the wireless board. As mentioned above, the module 508 includes one or more batteries 526 (see FIG. 14C ) to power the wireless board, PCB 511, sensor 510, and / or one or more actuators 512, 514, 516, 517. Recharging of the battery 526 can be achieved via a cable, wire, or cord on a detachable hand pendant (which may be storeable on the surgical table 100). In one embodiment, power to the wireless board, PCB 511, sensor 510, and / or one or more of the actuators 512, 514, 516, 517 may be available while the cable is connected (in case the battery 526 is dead or discharged).

[0071] Thus, the above-described techniques, in one embodiment, provide the operator with the ability to drive the operating table 100 forward and / or backward and / or maneuver with maximum leverage. The first attachment 500 can be mounted at either end of the operating table 100 (e.g., the head or foot end), allowing the operator to drive the operating table 100 from either end. To facilitate such functionality, the operating table 100 can automatically sense which end of the operating table 100 the first attachment 500 is mounted or attached to, and automatically adjust its anterior-posterior orientation to suit the operator's orientation. In the prior art, no device has been available that allows for such a global level of ergonomic control.

[0072] 14A-15, the free end of each arm 504a, 504b of the first attachment 500 (e.g., opposite the module 508 and cross beam 506) can include at least one protrusion 522a, 522b designed to be received in at least one receptacle or socket in the remainder of the operating table 100. The receptacle can be located or disposed on the upper platform 102, for example. Each protrusion 522a, 522b can include a tab or latch 534a, 534b rotatable about an axis 536 extending generally perpendicular to the plane defined by the plate 502 of the first attachment 500. At least a portion of each tab 534a, 534b is configured to engage a portion of the interior of a container. Those skilled in the art will understand that the above arrangement can be reversed (e.g., the receptacle on each arm 504a, 504b receives at least a portion of the protrusion from the remainder of the operating table 100) without impairing the functionality described herein.

[0073] In embodiments, the operating table 100 can use several different technologies in several different locations. For example, in one embodiment, the operating table 100 can use one or more three-axis magnetic sensors. These sensors can detect the presence of a magnet and its relative position along an arc. In particular, in one embodiment, one or more permanent magnets 544 (shown schematically in FIG. 15 ) can be positioned on or around the pivot axis of each gear 528 (described in more detail below) on or in the first attachment 500. More particularly, in one embodiment, a metal flange can be placed on the spindle between each gear 528 and a hex nut 546, including the permanent magnet 544. The three-axis magnetic sensors can be attached to the distal ends of the back and legs of the second attachment 800 and the third attachment 900 and can be positioned close enough to the magnets to (i) detect the presence of the attachment and (ii) identify or read the angle or rotation at which the attachment is attached. In one embodiment, two or more or all of the detachable attachments 500, 800, 900 employ three-axis magnetic sensor technology, even when the module 508 is not installed or in use.

[0074] Three-axis magnetic sensing technology may be used at or by the protrusions 522a, 522b and receptacles to enable the operating table 100 to sense components. Thus, at least one of the receptacles can detect the presence of, engagement with, and / or insertion angle relative to (i) the respective protrusions 522a, 522b (described in more detail below), or vice versa. One or more permanent magnets can be positioned on a rotatable portion of the first attachment 500 near one or both of the protrusions 522a, 522b. One or more three-axis magnetic sensors can be mounted in or on one or more of the receptacles. As will be appreciated by those skilled in the art, the three-axis magnetic sensors can detect the presence of the permanent magnets and determine the angular position of the permanent magnets, thereby determining the adjustment angle of the attachment 500. This detection can be completed wirelessly, allowing the first attachment 500 to be completely removed and separated from the rest of the operating table 100.

[0075] 15 , the free end of each arm 504a, 504b can include a gear and prong system. The gear and prong system can hold the prong 522a, 522b at a particular angle relative to the plate 502 and / or allow it to rotate or otherwise move relative to the plate 502 and then be held at that angle. More specifically, at least a portion of each prong 522a, 522b can be fixed relative to a gear 528. The gear 528 can include a plurality of spaced teeth extending around its entire circumference. Alternatively, the teeth of the gear 528 can be located on only a portion of its circumference. A prong 530 and a spring 532 can be located within a portion of the arm 504a, 504b. The spring 532 can surround at least a portion of the prong 530 and engage the prong 530, biasing the prong 530 to move toward and engage the gear 528. The opposite ends of the prongs 530 engage and are securely attached to brackets 540, which are slidable relative to the arms 504a, 504b. An angle adjustment / release handle 542 can be attached to the brackets 540 on either side of the first attachment 500. An operator or user can reach under the top surface 502 of the first attachment, grasp the angle adjustment / release handle 542, and pull. This action disengages each prong 530 from the gear 528. When the operator releases the angle adjustment / release handle 542, springs 532a, 532b re-engage the prongs 530a, 530b with the gear 528, locking them into the new position or angle.

[0076] As a result of the combination of the above features, the upper surface 502 of the first attachment 500 can have multiple configurations or positions relative to the upper surface of the upper platform 102. For example, the first upper surface 502 of the first attachment 500 can extend at an angle (e.g., adjusted upward or downward from 0 to 90 degrees) relative to the upper surface of the upper platform 102, even while the first attachment 500 is secured to the upper platform 102. In another embodiment (not shown), the upper surface 502 of the first attachment 500 can extend parallel to, but not necessarily coplanar with, the upper surface of the upper platform 102. For example, in such an embodiment, the upper surface platform 102 or the attachment 500 can still allow for angle adjustment, and the first attachment 500 can still include a drive-assist module.

[0077] The operating table 100 is also configured to use radio frequency identification (RFID) or another identification protocol. As described in more detail below, RFID technology can be used at the interface between the upper platform 102 and any removable attachments. In one embodiment, RFID technology can be used with the back and leg sections or attachments 800, 900, although options such as imaging boards can also be used. Because RFID tags can transmit serialized information, the system can use them to accurately determine what is attached to each location. Using this technology, the system can also pass a limited amount of power to distal devices to power sensors. In one embodiment, RFID technology is employed in two or more or all of the removable attachments 500, 800, 900, even when the module 508 is not installed or in use.

[0078] 16-18, in one example, the upper platform 102 or another portion of the operating table 100 can include two or more spaced apart sockets 850a, 850b. Each socket 850a, 850b can be sized, shaped, and / or configured to receive at least a portion of an extension 852a, 852b of one of the second attachments 800. RFID technology enables each socket 850 and extension 852 to communicate with other and / or remaining portions of the operating table 100. In particular, at least one of the sockets 850a, 850b and / or extensions 852a, 852b can sense (i) the presence, (ii) engagement with, and / or (iii) the angle of insertion.

[0079] One or more RFID tags and / or readers can be disposed in or on one or both of the extensions 852a, 852b and / or one or more of the sockets 850a, 850b. As will be appreciated by those skilled in the art, the tags and readers can communicate or exchange information. This sensing can be completed wirelessly. More specifically, in one embodiment, one or each extension 852a, 852b can include a first or “smart” RFID tag 854 capable of transmitting power. Each socket 850a, 850b can include a board or second RFID tag 856. The technology of this disclosure is not limited to including “smart” RFID tags, as “dumb” RFID tags that do not transmit power can be used.

[0080] As will be appreciated by those skilled in the art, the techniques of the present disclosure provide intelligent detection of one or more of the attachments. More specifically, the use of RFID technology allows the operating table 100 to not only detect the presence of a previously unattached attachment, but also identify specifically which attachment it is (i.e., the second attachment 800) and the orientation of that component (e.g., the second attachment 800 is attached to the foot end of the operating table 100 and / or the angle of the second attachment 800 relative to the upper platform 102). Furthermore, information obtained from RFID technology can be used to improve the accuracy of collision detection algorithms. As mentioned above, RFID technology transfers power wirelessly, which is one way to energize a three-axis magnetic sensor. Thus, RFID technology allows the operating table 100 to wirelessly detect (i) the presence and (ii) the location of two consecutive distal components. This is more than just a proximity sensor (which can recognize that some component is attached, but not the orientation of that component).

[0081] 19-24 show details of one embodiment of a base 400 of the disclosed technology. The base 400 can be formed with a stage 402 that can accommodate and / or support multiple components. The components can include (i) a drive assist mechanism 700 having one or more drive wheels 600, (ii) three, four, or more spaced caster wheels 404, and / or (iii) one, two, four, or more spaced load-sensing / floor-lifting mechanisms 406. The stage 402 can include one or more cutouts or openings 403 (see FIGS. 19-21A ) sized, shaped, and / or configured to accommodate the drive wheels 600. In one embodiment, each opening 403 is located near the head end of the operating table 100 and laterally centered. In alternative embodiments, each opening 403 and drive wheels 600 can be located at or near the center of the stage 402, or the drive wheels 600 can be two wheels on the outside of the stage. In one embodiment, each drive wheel 600 does not swivel or cast, however, in another embodiment, each drive wheel 600 includes this functionality.

[0082] 21B and 21C, the drive assist mechanism 700 can move the drive wheel 600 into and out of engagement with the ground 104 to allow or prevent the drive wheel 600 from moving the operating table. The drive assist mechanism 700 can include at least one motor that can communicate with the module 508 to selectively effect this rotation or slight pivoting of the drive wheel 600. The drive assist mechanism 700 can use a spring suspension system. Thus, in one embodiment, when the mechanism 700 moves the drive wheel 600 to the downward or engaged position, the spring suspension system always forces the drive wheel 106 downward into frictional contact with the ground 104, even though the drive wheel 600 is the fifth wheel that contacts the ground 104.

[0083] During transport, the operating table 100 can roll on the caster wheels 404, while at least a portion of each load sensing / floor-raising mechanism 406 (e.g., a support foot, described in detail below) can be retracted to a protective position and / or elevated off the ground 104. During non-transport conditions, such as surgery or storage, at least a portion of each load sensing / floor-raising mechanism 406 can be extended to contact the ground 104 and at least slightly elevate the base 400 off the ground 104, thereby preventing the caster wheels 404 from contacting the ground 104, which in turn prevents the operating table 100 from moving via the caster wheels.

[0084] Each load sensing / floor lifting mechanism 406 may include a support foot 408 with a rubberized bottom surface 410. The bottom surface 410 may provide the support foot 408 with a high coefficient of friction, such that when the support foot 408 is in the deployed or elevated position, the support foot 408 securely holds the operating table 100 in place. In operation, when the support foot 408 is actuated, the support foot 408 may move downward (e.g., approximately perpendicular to the plane defined by the upper platform 102) and initially contact the ground 102. When the support foot 408 is further actuated, the support foot 408 may lift the operating table 100, which in turn may lift each caster wheel 404 at least slightly off the ground 104.

[0085] 22-24, each load sensing / floor lifting mechanism 406 can include a vertical shaft 412 mounted within a vertical shaft bushing 414. The upper end of the threadable shaft 412 can engage a threaded nut 415. The nut 415 is contained within a housing by one or more radial bearings 416 and / or one or more thrust bearings 418. In one embodiment, the radial bearings 416 and thrust bearings 418 allow the nut 415 to rotate about a vertical axis while all other degrees of freedom are constrained. A transmission device, such as a timing belt pulley or gears, can be attached to the nut 415 and / or the vertical shaft 412. In one embodiment, a motor or gear motor 422 and drive pulley are mounted on an axis parallel to the vertical axis 415 and connected thereto via a timing belt 424 (or gear train). In operation of one embodiment, when the motor 422 is energized, the shaft 412 can be keyed to drive upward or downward, but cannot rotate.

[0086] A load cell support beam 426 can be attached to the bottom of the shaft 412. The load cell support beam 426 can be a passive member that supports a cantilevered load cell beam 428. The support foot 408 can be attached to an end of the load cell beam 428. The load cell beam 428 can include or be operably connected to one or more sensors, such as strain gauges, designed and / or oriented to measure the strain of the load cell beam 428 when a normal force is applied. With proper calibration, this combination can provide an accurate measurement of the force applied to the load cell beam 428, thereby allowing a user to know the amount of force applied to at least a portion of the operating table 100.

[0087] More specifically, in one embodiment, with four such devices attached to approximately (e.g., four) corners of the operating table 100, and the operating table 100 elevated at least slightly above the ground 104 by the extended support feet 408, an accurate measurement of the weight of the operating table 100 (including the patient and accessories) can be obtained. Additionally, because the forces applied to each corner of the operating table 100 are known, the stability of the operating table 100 can be determined. For example, if at least a portion of the upper platform 102 is extended in a horizontal plane, more weight is transferred to one end of the base 400, thereby increasing the force applied to two load cell sensors while decreasing the force applied to the other two sensors. A stability algorithm can be applied, allowing for the establishment of a minimum force threshold (taking into account disturbance forces applied by the surgeon or staff) required to achieve stability during normal operating room procedures.

[0088] 22 and 23, the load cell beam 428 and the load cell support beam 426 can have the same or nearly the same length and / or can be aligned such that the shaft 412 and the support foot 408 are coaxially aligned. Such a configuration helps to eliminate or reduce moment loads applied to the shaft 412, thereby minimizing frictional resistance using a simple bushing 414. However, such an arrangement is not required for the operating table 100 and / or the load sensing / bed lifting mechanism 406 to function as intended or described herein.

[0089] In one embodiment, the lift actuation algorithm can independently and / or separately drive each support foot 408 into the ground surface 104. Each motor 422 can drive each support foot 408 downward until a predetermined current value is reached. In one embodiment, this current value can be high enough to overcome expected friction in the drive, but not generate enough torque to lift the operating table 100 off the ground surface 104. In this manner, the position of the surface 104 can be independently sensed by each load sensing / floor lifting mechanism 406. For example, if a tile on the ground surface 104 is missing in one location, the associated support foot 408 will be driven further than the other three support feet 408. Once all four support feet 408 find or contact the ground surface 104, the algorithm can simultaneously drive all four lift assemblies.

[0090] As shown in FIG. 24, an encoder wheel 430 and an optical sensor 432 can be used to drive each support foot 408 a predetermined distance at the same or substantially the same speed, thereby allowing the operating table 100 to be at least slightly raised in a smooth and uniform manner to an operating height (e.g., the height to which each caster wheel 404 is raised above the ground 104). Once activated, the motors 422 can drive the shafts 412 in opposite directions until each support foot 408 is fully retracted (e.g., so that each caster wheel 404 contacts the ground and each support foot 408 is clear of the ground 104). The system can be configured to provide feedback to the operator of its position or repositioning, or the position of the load and / or loads applied to it (e.g., visually via a monitor, audibly via a speaker, etc.).

[0091] One or more of the techniques and / or embodiments described above may be implemented or include software, e.g., modules (see FIG. 25) executing on one or more computing devices 210. Of course, the modules described herein are indicative of various functions and do not limit the structure or functionality of the embodiments. Rather, the functionality of the various modules may be divided differently and performed by more or fewer modules according to various design considerations.

[0092] Each computing device 210 may include one or more processing devices 211 designed to process instructions, e.g., computer-readable instructions (i.e., code), stored in a non-transitory manner on one or more storage devices 213. Processing the instructions enables the processing devices 211 to perform one or more of the steps and / or functions disclosed herein. Each processing device may be real or virtual. In a multiprocessing system, multiple processing units execute computer-executable instructions to increase processing power. Storage 213 can be any type of non-transitory storage device (e.g., optical storage, magnetic storage, solid-state storage, etc.). Storage 213 can be removable or non-removable and can include magnetic disks, magneto-optical disks, magnetic tapes or cassettes, CD-ROMs, CD-RWs, DVDs, BDs, SSDs, or any other medium capable of storing information. Alternatively, the instructions may be stored in one or more remote storage devices, such as storage devices accessed over a network or the Internet.

[0093] Each computing device 210 may further have memory 212, one or more input controllers 216, one or more output controllers 215, and / or one or more communication connections 240. The memory 212 may be volatile memory (e.g., registers, cache, RAM, etc.), non-volatile memory (ROM, EEPROM, flash memory, etc.), or a combination thereof. In at least one embodiment, the memory 212 may store software that implements the described techniques.

[0094] An interconnection mechanism 214, such as a bus, controller, or network, may operatively couple components of computing device 210, including processor 211, memory 212, storage device 213, input controller 216, output controller 215, communication connection 240, and other devices (e.g., network controller, sound controller, etc.). Output controller 215 may be operatively coupled (e.g., via a wired or wireless connection) to one or more output devices 220 (e.g., a monitor, television, mobile device screen, touch display, printer, speaker, etc.) in a manner such that output controller(s) 215 can transform a display on display device 220 (e.g., depending on the module being executed). Input controller 216 may be operatively coupled (e.g., via a wired or wireless connection) to input device 230 (e.g., a mouse, keyboard, touchpad, scroll ball, touch display, pen, game controller, voice input device, scanning device, digital camera, etc.) in a manner such that input can be received from a user.

[0095] The communications connection(s) 240 may enable communication over a communications medium to another computing entity. The communications medium conveys information such as computer-executable instructions, audio or video information, or other data in a modulated data signal. A modulated data signal is a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of non-limiting example, communications media include wired or wireless techniques implemented with electrical, optical, RF, infrared, acoustic or other carriers.

[0096] 25 depicts computing device 210, output device 220, and input device 230 as separate devices solely for ease of identification. However, computing device 210, display device 220, and / or input device 230 may be separate devices (e.g., a personal computer connected by wires to a monitor and mouse), integrated into a single device (e.g., a mobile device with a touch display, such as a smartphone or tablet), or any combination of devices (e.g., a computing device operably connected to a touchscreen display device, multiple computing devices connected to a single display device and input device, etc.). Computing device 210 may also be one or more servers, e.g., a farm of networked servers, a clustered server environment, or a cloud service running on a remote computing device.

[0097] Those skilled in the art will appreciate that changes could be made to the above-described embodiments without departing from the broad inventive concept thereof. For example, various mechanical and electrical connection elements and actuators could be used to achieve the disclosed functionality. It is understood, therefore, that the invention is not limited to the particular embodiments disclosed, but rather that it is intended to cover modifications within the spirit and scope of the invention as defined by the appended claims.
