Description

[0001] The invention relates to a ceiling-mounted stand for a ceiling-supported medical device, comprising a ceiling trolley adjustable along a ceiling and a telescopically extendable and retractable telescopic section attached thereto, with several telescopic segments guided together and adjustable relative to one another. The medical device is attached to an outer end of the telescopic section, located away from the ceiling trolley.

[0002] The ceiling-mounted stand serves to provide various degrees of freedom of movement, in particular translational and / or rotational degrees of freedom, for the medical facility.

[0003] In the field of medical technology, ceiling-mounted medical devices are known to be attached to the ceiling, particularly the ceiling of an examination room, via a ceiling stand. They thus form a ceiling-mounted component of medical systems, which can be, for example, imaging devices such as C-arm X-ray units or radiography imaging systems. For instance, the X-ray tube and / or the X-ray detector can be positioned at the ends of the telescopically extendable and retractable section to allow adjustment of the respective imaging component in various directions. Non-imaging medical devices, such as radiotherapy equipment, can also be suspended or mounted using ceiling stands.

[0004] Typically, electrical components of a medical device, particularly X-ray tubes, apertures, actuators, sensors, and / or detectors, must be connected via numerous cables or supply lines. In known devices, the necessary cable routing is achieved through at least one cable bundle running from the ceiling, outside the ceiling mount, through at least one corrugated conduit to the medical device. The corrugated conduit forms an outer sheath for the cable bundle, primarily protecting it from mechanical damage and contamination. The conduit also provides sufficient cable length to allow the medical device to be positioned in any desired location by adjusting the ceiling mount. Both the cable bundle and the conduit must be sufficiently flexible to accommodate any desired adjustment of the ceiling mount and the medical device, respectively.to follow up. Since the movement of the cables guided in the corrugated conduit is largely undefined, increased wear of the individual cables is to be expected. Due to the surface properties of corrugated conduits, they are also difficult to clean, which proves particularly disadvantageous in the medical field, where high hygiene standards must be maintained. Furthermore, it has been observed that while corrugated conduits do move passively when the ceiling stand is adjusted, they assume undefined and, in particular, non-reproducible positions in space. This increases the stand's footprint, can disrupt the course of a medical procedure, impair access to the patient or medical equipment, and / or compromise the safety of the patient or medical personnel.

[0005] To reduce the range of motion of the corrugated hose, it is known, for example, to provide energy chains in or near a ceiling-mounted guide system for longitudinal or transverse movement of the ceiling stand along the ceiling, in which the cable harness is guided, at least in sections. It is also known to fix the cable harness or the corrugated hose at least at one or a few connection points on the housing of the ceiling trolley and / or the telescopic section housing. Manual adjustment maneuvers of the medical device by medical personnel are increasingly being replaced by autonomous adjustment maneuvers of the medical device.However, autonomous movement requires continuous, automated, sensor-based path planning and / or collision monitoring, which can only generate reliable outputs that meet clinical safety requirements if the actual, constantly changing dimensions of the ceiling stand, caused by the movement of the grooved tube, can be reliably recorded. The resulting need for updates also increases the computational effort.

[0006] Based on this prior art, the present invention aims to improve cable management in ceiling-mounted medical devices. In particular, the invention focuses on providing means that advantageously simplify the autonomous movement of a ceiling-mounted medical device and reduce the associated computational effort without restricting the freedom of movement of the medical device. Furthermore, the present invention aims to provide a ceiling-mounted medical device that is particularly easy to clean. The present invention also aims to provide a space-optimized ceiling stand for a medical device. This objective is achieved by a ceiling stand with the characterizing features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

[0007] The invention relates to a ceiling-mounted stand for a ceiling-supported medical device. The ceiling-mounted stand comprises - a ceiling trolley adjustable along a ceiling and - a telescopically extendable and retractable telescopic section attached to it, with several telescopic segments guided together and adjustable relative to each other.

[0008] The ceiling trolley can be attached to the ceiling via a guide system, which is known per se. This guide system can have guide rails running longitudinally and transversely. The longitudinal and transverse directions are typically arranged at a 90° angle to each other. The ceiling trolley can be designed to move along the guide rails, allowing the ceiling stand and medical equipment to assume a variety of positions relative to the ceiling.

[0009] According to the invention, the medical device is connected to the telescopic section. The medical device is preferably arranged at an end of the telescopic section facing away from the ceiling carriage. In particular, the medical device is connected to the outermost, lowest telescopic segment, which is located on the outside of the end of the telescopic section facing away from the ceiling carriage. Furthermore, according to the invention, the medical device is rotatably adjustable about a horizontal axis relative to the telescopic section. The horizontal axis preferably runs through the medical device or through the point of attachment of the medical device to the telescopic section. This horizontal axis of rotation allows the medical device to be inclined or tilted relative to the telescopic section.

[0010] The telescopic section is attached to the ceiling carriage. The telescopic section extends vertically downwards, i.e., towards the floor. It comprises several, at least two, preferably three or four, telescopic segments. These can have a uniform or differing profile shape; for example, they can each be designed as a closed or open O- or H-profile. The telescopic segments are guided against each other along their vertically oriented longitudinal axis. Specifically, one telescopic segment is guided against an adjacent telescopic segment. For this purpose, the telescopic segments can be arranged side by side, one behind the other, or interlocking within their profile. Accordingly, each telescopic segment includes at least one guide element that interacts with a guide element of an adjacent telescopic segment.Through the guided adjustment movement of the telescopic segments, they can be arranged essentially parallel to each other, overlapping lengthwise. One telescopic segment can therefore be guided and moved by another. This guided adjustment movement allows the telescopic section to be extended or retracted along a vertical axis running through it, thus adjusting the height of the medical device between a maximum height (maximum overlap of the telescopic segments along the vertical axis) and a minimum height (minimum overlap of the telescopic segments along the vertical axis).

[0011] The medical device can be configured, for example, as an imaging or therapeutic X-ray source, an X-ray detector, a C-arm X-ray unit, or similar equipment. The medical device or ceiling-mounted stand can each be part of a medical system and interact with other components of the same system, such as an X-ray detector, a patient table, or similar items.

[0012] According to the invention, the telescopic section is also rotatably adjustable relative to the ceiling carriage about the vertical axis running within the telescopic section. This vertical axis of rotation, together with the horizontal axis of rotation of the medical device, enables a multitude of angular positions for the medical device in the examination environment and, in particular, relative to a patient.

[0013] According to the invention, the ceiling-mounted stand comprises a cable management module for routing multiple supply lines in at least one cable bundle. A supply line can be, in various embodiments, a data line, a cable for supplying power to electrical or electronic components of the medical device, or a line for supplying an operating medium, e.g., compressed air. In a particularly preferred embodiment, the cable bundle comprises a plurality, e.g., 10, 15, or more supply lines.

[0014] The cable management module extends from the ceiling trolley, across the telescopic section, to the medical device. The cable management module includes at least one cable reserve for adjusting the ceiling stand about the vertical axis, along the vertical axis, and / or about the horizontal axis, and runs largely, substantially, or completely within a stand housing. In embodiments of the invention, the cable reserve facilitates movement along at least one of the degrees of freedom of the ceiling stand; it can additionally facilitate movement along at least one further degree of freedom. In other words, the cable reserve is designed to provide a cable length such that the ceiling stand can move in at least one direction of movement between two positions of maximum deflection along that direction.

[0015] The tripod housing acts as a casing for all other components of the tripod housing, forming an outer surface or boundary of the ceiling tripod. In a preferred embodiment of the invention, it is formed by a plurality of housing parts or housing sections. These can advantageously be designed to be movable relative to one another in order to perform an adjustment movement of the ceiling tripod. The tripod housing preferably comprises at least a ceiling trolley housing, a telescopic housing, and a housing for the medical device. In other words, the cable management module runs entirely inside the ceiling tripod and is neither visible nor accessible from the outside.

[0016] The ceiling-mounted stand according to the invention comprises at least two rotational and one translational degree of freedom. This allows for highly flexible positioning of the medical device. The cable management module, comprising one or more cable reserves, is fully integrated within the ceiling-mounted stand. Its external shape, its footprint, or outer contour is therefore known in every stand position, reliably reproducible, and advantageously small. This facilitates autonomous path planning. The compact design generally reduces the risk of collisions, particularly during (autonomous) movement of the stand. The surface of the stand housing can be smooth and dirt-repellent in accordance with hygienic standards; for example, some versions may also feature an antibacterial coating on the surface.The invention does without corrugated tubing, so that the ceiling stand according to the invention is particularly well suited to the hygiene requirements of medical technology.

[0017] In preferred designs, the cable harness in the guide system for the longitudinal and transverse movement of the ceiling stand / ceiling trolley can continue along the ceiling, e.g. in one or more energy chains.

[0018] One embodiment of the ceiling-mounted tripod provides that the cable management module comprises at least one, preferably several, cable management elements arranged in series. In embodiments of the cable management module, a cable management element can be designed as an energy chain, a protective conduit, or a corrugated conduit. The cable management module can, in some embodiments, comprise several different cable management elements, with different cable management elements being arranged section by section along the cable bundle. Alternatively or additionally, the cable bundle can also run freely within the tripod housing, at least in sections.

[0019] A particularly preferred embodiment of the ceiling stand comprises a cable management module with at least one energy chain, preferably a plurality of energy chains arranged one behind the other, each of which is shear-resistant and bendable.

[0020] An energy chain (also called energy guide chain, E-chain, or drag chain) comprises several chain links designed to guide longitudinal sections of cables or wires. The chain links are connected to each other via joints, the axes of which, for example, run parallel to one another. Energy chains can be designed as open or closed chains. Closed energy chains completely enclose the cable or cables within them. Open energy chains have openings in the material, so the cables are generally not completely enclosed circumferentially. Energy chains can also be compartmentalized along their length, with individual cables or groups of cables being guided in one of the compartments.By appropriately arranging the energy chain in the ceiling stand and dividing the supply lines into different compartments of the energy chain, particularly sensitive supply lines can be protected.

[0021] Energy chains are generally designed to be both shear-resistant and flexible, defining minimum bending radii for the cables they guide, thus preventing undefined cable movements. Energy chains are particularly suitable for reducing the mechanical stress acting on the cables. At least one energy chain is advantageously designed to be shear-resistant and is especially suitable for strain relief of the cables or supply lines guided within it. In certain positions of the ceiling-mounted stand, the energy chain can have loop-shaped sections of relatively large extent to maintain the correct or required cable length. In other stand positions, the energy chain can be essentially straight. The energy chain is preferably designed to be flexible or bendable so that it can support stand movement along or around all axes of movement.

[0022] In preferred embodiments, the cable management module comprises two or more energy chains arranged in series. Accordingly, at least one first energy chain, representing a first section of the cable management module, and at least one second energy chain, representing a second section of the cable management module, are provided. The same cables / supply lines can be routed in the first and second energy chains. Particularly preferably, the cable management module thus comprises at least one energy chain running within the ceiling carriage, at least one further energy chain running within the telescopic section, and at least one further energy chain belonging to the medical device. The third energy chain can be arranged within the medical device and / or at least partially within the telescopic section, as will be explained in more detail below.In other words, the cable management module can comprise a plurality of energy chains, each assigned to at least one degree of freedom of the ceiling stand and, in particular, each providing a cable reserve for at least one degree of freedom of movement of the ceiling stand. In these embodiments, each energy chain can form a section of the cable management module or be assigned to a section of the cable management module. For example, in some embodiments, one or more energy chains can be arranged in the ceiling trolley and / or in the telescopic section.

[0023] A particularly advantageous embodiment of the ceiling-mounted tripod features a cable management system for the supply lines, which extends across the ceiling carriage and the telescopic section. In this embodiment, the cable management system provides not only a reserve of cable length for the rotation of the telescopic section around its vertical axis, but also a reserve for the extension of the telescopic section along its vertical axis. Preferably, the cable management system in this embodiment is configured to run in both horizontal and vertical orientations and is further designed to perform at least one change of direction from horizontal to vertical, i.e., a bend of at least 90°. Thus, the transition of the cable bundle between the ceiling carriage and the telescopic section is continuous. In these embodiments, no connection points for the cable management system are required at the interface / transition between the ceiling carriage and the telescopic section.Instead, in this design, the energy chain is fixed only at a first attachment point inside the ceiling carriage and at a second attachment point at the lower end, preferably the last, lowest, outermost telescopic segment. Between these points, the energy chain is flexibly, bendably, and, in particular, slidably mounted.

[0024] In a further embodiment, the cable management module comprises a first cable reserve arranged in the ceiling trolley housing and designed to allow rotation of the telescopic section about the vertical axis. Particularly preferably, the at least one energy chain introduced at the beginning forms the first cable reserve in the ceiling trolley housing. The first cable reserve therefore comprises at least one, or alternatively several, energy chains and a length sufficient to rotate the telescopic section in both directions to its maximum deflection about the vertical axis. Particularly preferably, the first cable reserve is designed to cover a rotation angle of the telescopic section of ±180°.

[0025] In other embodiments, the first cable reserve arranged in the ceiling carriage is also designed to allow the telescopic section to be adjusted between a maximum and a minimum height. In these embodiments, the first cable reserve includes a second cable reserve inserted further down, which in these embodiments is arranged outside the telescopic section, at least temporarily and in certain sections. The second cable reserve also includes one or more energy chains in some embodiments. Particularly preferably, the first and / or the second cable reserve is also designed to allow the telescopic section to extend by approximately 180 cm.

[0026] The first cable reserve preferably runs in a horizontal and / or vertical orientation; particularly preferably, the first cable reserve runs primarily in a vertical or horizontal plane. For a vertical orientation of the first cable reserve within the ceiling trolley, an additional housing segment for the trolley housing can advantageously be provided to accommodate the first cable reserve to a large extent. This segment is positioned in such a way that other components of the trolley, such as a drive mechanism or the movement of the medical device at its maximum height, etc., are not affected. For a horizontal orientation of the first cable reserve, particularly preferably in a plane, unused space within the trolley can be advantageously utilized, thus avoiding the need for an extension / enlargement of the trolley and keeping its overall dimensions as small as possible.

[0027] In further preferred embodiments, the first cable reserve comprises a winding mechanism including means for torsional compensation or an energy chain with a reverse bending radius. A winding mechanism can, in particular, comprise a cable reel or drum onto which the energy chain is wound, at least partially, when the first cable reserve is not needed or only partially needed. The orientation of the winding mechanism (vertically or horizontally arranged winding axis) preferably corresponds to the orientation of the first cable reserve in the overhead carriage. A winding mechanism offers the advantage that the first cable reserve is arranged in an organized and space-saving manner when not in use. Alternatively, the first cable reserve, particularly in a vertical orientation, can be positioned in the further housing segment solely by its shear stiffness and by means of its weight when not in use.This variant reduces the component complexity of the ceiling-mounted tripod. In these versions, the first connection point for the energy chain is located on the winding mechanism. Depending on the shape of the first cable reserve, a second connection point can then be located on the uppermost, outermost telescopic segment or on the lowermost, outermost telescopic segment.

[0028] Forming the first cable reserve using an energy chain with a reverse bending radius is particularly advantageous in designs where the first cable reserve only serves the rotation of the telescopic section around the vertical axis and is horizontally oriented. An energy chain with a reverse bending radius is characterized by chain links that, at least in sections, allow bending / curvature of the energy chain in two opposite directions, while suppressing curvature in the perpendicular direction. In other words, an energy chain with a reverse bending radius can, in particular, assume an S-shape or a mirrored S-shape, which runs stably in a horizontal plane. In these designs, a first attachment point of the energy chain can be located at a fixed point within the overhead carriage.A second attachment point for the energy chain can again be located on the uppermost, outermost telescopic segment of the telescopic section. In some designs of the first cable reserve, this second attachment point can be selected such that the energy chain winds itself onto the uppermost, outermost telescopic segment depending on its angular position.

[0029] In other versions of the ceiling stand, the cable management module includes a second cable reserve, as mentioned above, which is located within the telescopic section and allows the stand to be adjusted along the vertical axis. This second cable reserve is thus directly related to, or accommodates, the change in length of the telescopic section along the vertical axis. In these versions as well, it is advantageous that the second cable reserve is housed entirely inside the ceiling stand, specifically within the telescopic section, without significantly or obstructively increasing the required installation space. The second cable reserve can again be designed as one or more cable chains, in which the cable runs. At least one cable chain can extend between a first attachment point on the uppermost, outermost telescopic segment and a second attachment point on the lowermost, outermost telescopic segment.Depending on the number of energy chains involved, the second cable reserve can be fixed to a central telescopic segment via at least one additional attachment point. Advantageously, the second cable reserve has a length that corresponds to the length of the telescopic section in its maximum extended position, corresponding to its minimum height.

[0030] In other embodiments, the second cable reserve comprises one or more protective conduits arranged along the cable bundle, in which the cable bundle is enclosed or runs. In still other embodiments, the cable bundle in the second cable reserve can also be arranged freely, at least in sections, i.e., without an energy chain or protective conduit. In further embodiments, the second cable reserve can include an energy chain and a protective conduit, at least in sections. In these embodiments as well, the second cable reserve can be fixed and held by at least two connection points, as described above in relation to the embodiment with at least one energy chain.

[0031] The second cable reserve can particularly preferably be formed by a cable strand with at least two loops within the telescopic section, forming at least a partially looped or meandering course. In embodiments with exactly two loops, the cable strand, preferably surrounded by an energy chain, runs along the telescopic segments such that the loop openings are oriented in opposite directions in the vertical direction when the telescopic section is in its maximum retracted state (= maximum height).

[0032] In versions of the second cable reserve with more than two loops, the loop openings are preferably horizontally oriented. In particular, each connection point can include a fixing clamp, which secures the cable harness / energy chain to the multiple telescopic segments, with each fixing clamp advantageously providing some play to allow relative movement between the cable harness / energy chain and the fixing clamp.

[0033] In particularly preferred embodiments of the ceiling-mounted stand, at least one loop, and more preferably both or all loops, of the second cable reserve can be guided over a deflection pulley, preferably arranged on a central telescopic segment. When the telescopic section moves along the vertical axis, the at least one deflection pulley moves relative to the first and / or second attachment point of the cable bundle / energy chain of the second cable reserve, ensuring guided and thus controlled stretching or bending of the energy chain. Alternatively, the cable bundle / energy chain can be held at at least one intermediate attachment point on at least one of the central telescopic segments by means of suitable fixing clamps. Advantageously, the fixing clamps allow relative movement between the cable bundle / energy chain and the fixing clamp.

[0034] The ceiling mount is particularly space-optimized in versions where the cable management module in the telescopic section comprises two sub-strands, each accommodating at least one supply line. This design efficiently utilizes available, currently unused space within the telescopic section. An increase in the required space is largely avoided or limited to a level that is imperceptible during use and / or does not restrict the mount's freedom of movement. Instead of one thick and therefore less flexible cable strand, two thinner sub-strands are used. Each sub-strand advantageously includes an energy chain for accommodating, guiding, and protecting the enclosed supply lines. Reducing the diameter of the cable strand also allows for a reduction in the required bending radii.In a preferred embodiment, each of the sub-strands provides a second cable reserve. In other words, each of the two sub-strands can be configured as described above with regard to the second cable reserve. Advantageously, both sub-strands are configured identically, i.e., both sub-strands have the same number of loops and attachment points.

[0035] In designs that maximize the use of available space, each of the two sub-strands is positioned offset from the vertical axis on opposite sides of the telescopic segments, such that a predefined maximum rotation radius of the telescopic section is maintained. The arrangement of the two sub-strands is particularly preferably mirror-symmetrical and laterally offset from the vertical axis. In typical designs, the predetermined rotation radius of the telescopic section is defined by its depth, not its width. The depth of the telescopic section is typically determined by the shape and dimensions of the individual telescopic segments in profile or in a top view. The telescopic segments are typically arranged one behind the other in the depth direction, resulting in the greatest extent of the telescopic section in this direction.

[0036] If the second cable reserve is already included in the first cable reserve in the ceiling trolley, the energy chain running in the ceiling trolley and the telescopic section can be laid linearly and parallel to the vertical axis along the length of the telescopic section. The telescopic section then advantageously includes only one second connection point for the energy chain, located on the lowest, outermost telescopic segment. From there, the cable bundle is transferred to the medical equipment.

[0037] An external corrugated hose along the telescopic section can thus be advantageously omitted, regardless of the design of the second cable reserve, without having to adjust the existing external dimensions of the telescopic section (noticeably to a user). Advantageously, in further preferred embodiments, the ceiling-mounted stand includes a third cable reserve, which is at least partially located within the telescopic section and / or the medical device and allows the medical device to be adjusted around the horizontal axis. The third cable reserve also preferably includes an energy chain in which the cable bundle is received, guided, and protected. The third cable reserve is associated with the rotation of the medical device around the horizontal axis. It therefore has a length sufficient to rotate the medical device in both directions to its maximum deflection around the horizontal axis.The third cable reserve is particularly well-designed to cover a rotation angle of the medical device from ±130° to ±180°, the angle range need not be symmetrical.

[0038] Particularly preferably, the third cable reserve also comprises a winding mechanism, at least one loop, and / or an energy chain with a reverse bending radius. Particularly preferably, the third cable reserve runs vertically, especially in a vertical plane. This is especially the case when the third cable reserve comprises an energy chain with a reverse bending radius. The properties of this energy chain configuration have already been described with reference to the first cable reserve and also apply to the third cable reserve. In particular, the energy chain with the reverse bending radius is fixed at a first attachment point on the lowest outer telescopic segment. A further, second attachment point is preferably provided on the medical device.In particular, the energy chain is designed to wind itself, at least partially, around the horizontal axis, regardless of the direction of rotation of the medical device, when the medical device changes its angular position. In this respect, the horizontal axis can serve as a winding mechanism for the third cable reserve.

[0039] Alternatively, the energy chain can be wound up via an additional winding mechanism, a cable reel, or a cable drum, independent of the horizontal axis, when the third cable reserve is not currently needed. This winding mechanism is also preferably vertically oriented and extends either entirely within the housing of the medical device, entirely within the housing of the telescopic section, or is divided between both housings. In this way, the third cable reserve can be wound in a loop or spiral, at least temporarily and in sections.

[0040] Particularly in ceiling-mounted stand configurations where the medical device includes an X-ray source or X-ray tube, the third cable reserve can be designed as an energy chain with a reverse bending radius, advantageously vertically oriented, and space-optimized between the high-voltage connections of the X-ray source. In this configuration, the third cable reserve runs entirely within the housing of the medical device.

[0041] Further advantages, features, and details of the invention will become apparent from the exemplary embodiments described below and from the drawings.

[0042] The Fig. 1, Fig. 3 and Fig. Figure 5 shows illustrations of a ceiling stand DS according to the invention, comprising a cable management module KM, in various embodiments. First, features of the ceiling stand DS that are comparable in the different embodiments are described. Then, with reference to the individual figures, the differences between the embodiments are discussed in more detail.

[0043] The ceiling-mounted stand DS serves to support and move a medical device ME (not shown in detail here). The stand DS comprises a ceiling trolley DW, adjustable along the ceiling in both longitudinal and transverse directions, at least by means of a guide system not described in detail here. The trolley is bounded externally by a ceiling trolley housing DWG. A telescopic section TT, extendable downwards towards the floor or subfloor, is attached to the ceiling trolley DW and may extend at least partially within the ceiling trolley DW. The telescopic section TT comprises several telescopic segments TS1, TS2, TS3, and TS4 (not described in detail here), which are adjustable relative to one another and, in particular, guided within or against each other. The telescopic section TT also includes a telescopic section housing TTG, which may contain several housing sections, one for each of the telescopic segments.The medical device ME is arranged on the lowest, outermost telescopic segment TS4, and is connected laterally to the lowest telescopic segment TS4. The medical device ME also has a housing MEG, which is formed from at least one housing section.

[0044] By extending and retracting the telescopic section TT along the vertical axis VA, which runs through the telescopic section TT, the medical device ME can be adjusted in height between a maximum and a minimum height. The telescopic section TT is also rotatably mounted around the vertical axis VA in the ceiling trolley DW. In some versions, this rotation can cover an angular range of, for example, ±180°; in others, the angular range may be smaller. Furthermore, the medical device ME is rotatably mounted on the telescopic section TT around the horizontal axis of rotation, the horizontal axis HA. Via the vertical axis VA and the horizontal axis HA, the ceiling stand DS provides at least three degrees of freedom of movement for the medical device ME.

[0045] The medical device ME is supplied with energy or a working medium such as compressed air or similar via a multitude of supply lines VL, which are routed from the ceiling to the medical device ME within a cable management module KM. The cable management module KM therefore extends across the ceiling trolley DW, the telescopic section TT, and up to the medical device ME, and is designed to carry a multitude of supply lines VL in at least one cable bundle. The cable management module KM includes at least one cable reserve KR1, KR2, KR3 for adjusting the ceiling stand DS around the vertical axis VA, along the vertical axis VA, and / or around the horizontal axis HA. The cable management module KM is entirely enclosed within a stand housing SG.

[0046] In the design of the DS ceiling tripod according to Fig. 1, Fig. 3 and Fig. 5 the cable guidance module KM comprises at least one, more precisely more than one energy chain EK, EKr, namely a plurality of energy chains EK, EKr arranged one behind the other along the cable string, each of which is shear-stiff and / or bendable and / or flexurally stiff.

[0047] The cable routing module KM from the version according to Fig. Section 1 comprises a first cable reserve KR1. This is arranged in the ceiling trolley housing DWG and is designed to allow rotation of the telescopic section TT about the vertical axis VA. For this purpose, the first cable reserve KR1 is designed in the form of an energy chain with a reverse bending radius EKr, the energy chain EKr being arranged in a horizontal orientation in the ceiling trolley DWG. The energy chain with reverse bending radius EKr allows the cable strand to assume opposing curves in a horizontal plane in sections.

[0048] Fig. Figure 2 shows in this context a top view of the ceiling trolley DW and the telescopic part TT of the ceiling tripod DS partially arranged therein, according to Fig. Figure 1 shows a detailed view of the cable management module KM in various positions of the telescopic section TT. The vertical axis VA, around which the telescopic section TT can rotate, extends into the image plane. The first cable reserve KR1, in the form of the energy chain with a rearward bending radius EKr, is located in Fig. Figure 2 shows the energy chain in three different positions S1, S2, and S3. It is understood that in reality, these positions can only be assumed sequentially. The energy chain with a reverse bending radius EKr is fixed in its horizontal plane only by a connection point AP, which is fixed relative to the overhead carriage DW, and a connection point AP, which is rotatable around the vertical axis VA with the telescopic section TT. For simplicity, the rotatable connection point AP is located on the uppermost telescopic segment TS1, which projects into the overhead carriage DW and the horizontal plane of the first cable reserve KR1. Due to the bending and shear rigidity of the energy chain EKr, it is moved solely by the rotation of the rotatable connection point AP together with the telescopic section TT around the vertical axis VA from the first position S1 to the third position S3, inevitably passing through the second position S2.

[0049] In both the first and third positions S1, S3, the first cable reserve KR1 is at least partially wound or coiled on the telescopic part TT.

[0050] In alternative versions (not shown) for the first cable reserve KR1, which is assigned to the rotation around the vertical axis VA, a winding mechanism AM rotatable around a second vertical axis in the form of a cable reel can be provided in the ceiling trolley DW.

[0051] The horizontal plane of the first cable reserve KR1 lies according to the design of Fig. 1 space-optimized within the cuboid-shaped ceiling trolley housing DWG.

[0052] The in Fig. The illustrated embodiment of the DS ceiling tripod further includes a second cable reserve KR2, which is designed to provide sufficient cable length for an adjustment movement of the telescopic section TT along the vertical axis VA. In other words, it includes Fig. 1 the cable management module KM a second cable reserve KR2, which is arranged in the telescopic part TT and allows adjustment of the ceiling tripod DS along the vertical axis VA.

[0053] The second cable reserve KR2 is also formed by at least one energy chain EK, wherein the second cable reserve KR2 is formed by an at least partially loop-shaped course of the cable strand guided in this energy chain EK comprising at least two loops, and wherein the second cable reserve KR2 is arranged completely or largely within the telescopic part TT.

[0054] With reference to the Fig. 6, Fig. 7, Fig. 8 and Fig. Section 9 describes the details of the second cable reserve KR2. Fig. Figure 6 shows a side view of a ceiling stand DS according to the invention with a cable management module KM comprising a second cable reserve KR2 in one embodiment. Fig. Figure 7 shows a detailed view of the telescope part TT and the second cable reserve KR2 according to Fig. 6.

[0055] The in Fig. The ceiling-mounted stand DS shown in Figure 6 is in a position where the medical device ME is at its maximum height. The telescopic section TT is fully retracted, the individual telescopic segments TS1 to TS4 overlap to their maximum extent, and the distance between the medical device ME and the ceiling trolley DW is minimal. In this embodiment, the adjustment movement of the telescopic section TT is achieved via the cable spring mechanism SFZ, which is at least partially shown and can be of a known design. In alternative embodiments not shown, the cable spring mechanism SFZ can also be a motor-driven cable pulley, particularly with regard to autonomous movements of the ceiling-mounted stand DS.

[0056] Fig. Figure 6 shows a loop-shaped arrangement of the second cable reserve KR2, comprising exactly two loops whose loop openings are vertically oriented. A first attachment point AP of the energy chain EK forming the second cable reserve KR2 is located on the uppermost, outermost telescopic segment TS1, and a second attachment point AP is located on the lowermost outermost telescopic segment TS4. Between these two points, the energy chain EK is guided only by a deflection pulley UR located on another, middle telescopic segment TS3. Further attachment points AP along the telescopic section TT are unnecessary in this design.

[0057] When the telescopic section TT is extended or compressed along the vertical axis VA, the deflection pulley UR is displaced relative to the two attachment points AP of the energy chain EK. In particular, the deflection pulley UR assumes positions that lie between the two attachment points AP with respect to the vertical axis VA. In this way, and by utilizing the weight force also acting on the rest of the energy chain EK, the shear- and flexurally stiff energy chain EK is additionally stabilized and guided in its movement.

[0058] When the telescopic section TT is extended, the two loops are essentially fully extended / unfolded until the minimum height of the medical device ME is reached. When compressed, the two loops inevitably reform due to the guidance via the pulley UR and the force of gravity.

[0059] A particularly advantageous, space-optimized version of the second cable reserve KR2 is used in Fig. Figure 7 shows the cable routing module KM in general, and in particular the second cable reserve KR2, comprising two sub-strands KR21 and KR22 in the telescopic section TT. Each of the sub-strands KR21 and KR22 is designed to accommodate at least one supply line VL.

[0060] Specifically, the first sub-strand KR21, which is designed in the form of a first energy chain EK, accommodates two high-voltage supply lines VL, whereas the second sub-strand KR22 bundles all other supply lines VL within itself.

[0061] The two partial strands KR21 and KR22 are offset from the vertical axis VA on opposite sides of the telescope segments TS1, TS2, TS3, TS4 such that a predefined maximum radius of rotation r R of the telescopic part TT, which is largely determined by the dimensioning, shaping and guiding of the telescopic segments TS1-TS4 into each other, can be maintained.

[0062] The available installation space within the width of the telescopic section TT can therefore be used for the second cable reserve KR2, as long as the maximum rotation radius r R The required dimensions are maintained. By dividing the supply lines VL into two sub-strands KR21 and KR22, the additional installation space required can be kept to a minimum. The individual housing sections forming the telescopic housing TTG can also be easily adapted to the modified installation space of the telescopic section TT.

[0063] With reference to the Fig. 6, Fig. 7, Fig. 8 and Fig. Section 9 describes the details of the second cable reserve KR2. Fig. Figure 6 shows a side view of a ceiling stand DS according to the invention with a cable management module KM comprising a second cable reserve KR2 in one embodiment. Fig. Figure 7 shows a detailed view of the telescope part TT and the second cable reserve KR2 according to Fig. 6.

[0064] The in Fig. The ceiling-mounted stand DS shown in Figure 6 is in a position where the medical device ME is at its maximum height. The telescopic section TT is fully retracted, the individual telescopic segments TS1 to TS4 overlap to their maximum extent, and the distance between the medical device ME and the ceiling trolley DW is minimal. In this embodiment, the adjustment movement of the telescopic section TT is achieved via the cable spring mechanism SFZ, which is at least partially shown and can be of a known design. In alternative embodiments not shown, the cable spring mechanism SFZ can also be a motor-driven cable pulley, particularly with regard to autonomous movements of the ceiling-mounted stand DS.

[0065] Fig. Figure 6 shows a loop-shaped arrangement of the second cable reserve KR2, comprising exactly two loops whose loop openings are vertically oriented. A first attachment point AP of the energy chain EK forming the second cable reserve KR2 is located on the uppermost, outermost telescopic segment TS1, and a second attachment point AP is located on the lowermost outermost telescopic segment TS4. Between these two points, the energy chain EK is guided only by a deflection pulley UR located on another, middle telescopic segment TS3. Further attachment points AP along the telescopic section TT are unnecessary in this design.

[0066] When the telescopic section TT is extended or compressed along the vertical axis VA, the deflection pulley UR is displaced relative to the two attachment points AP of the energy chain EK. Specifically, the deflection pulley UR assumes positions that lie between the two attachment points AP with respect to the vertical axis VA. In this way, and by utilizing the weight force acting on the rest of the energy chain EK, the shear- and flexurally rigid energy chain EK is further stabilized and guided in its movement. When the telescopic section TT is extended, the two loops are essentially fully extended / unfolded until the minimum height of the medical device ME is reached. When it is compressed, the two loops are inevitably reformed due to the guidance provided by the deflection pulley UR and the weight force.

[0067] A particularly advantageous, space-optimized version of the second cable reserve KR2 is used in Fig. Figure 7 shows the cable routing module KM in general, and in particular the second cable reserve KR2, comprising two sub-strands KR21 and KR22 in the telescopic section TT. Each of the sub-strands KR21 and KR22 is designed to accommodate at least one supply line VL.

[0068] Specifically, the first sub-strand KR21, which is designed in the form of a first energy chain EK, accommodates two high-voltage supply lines VL, whereas the second sub-strand KR22 bundles all other supply lines VL within itself.

[0069] The two partial strands KR21 and KR22 are offset from the vertical axis VA on opposite sides of the telescope segments TS1, TS2, TS3, TS4 such that a predefined maximum radius of rotation r R of the telescopic part TT, which is largely determined by the dimensioning, shaping and guiding of the telescopic segments TS1-TS4 on or into each other, can be maintained.

[0070] The available installation space within the width of the telescopic section TT can therefore be used for the second cable reserve KR2, as long as the maximum rotation radius r R The required dimensions are maintained. By dividing the supply lines VL into two sub-strands KR21 and KR22, the additional installation space required can be kept to a minimum. The individual housing sections forming the telescopic housing TTG can also be easily adapted to the modified installation space of the telescopic section TT.

[0071] Fig. Figure 8 further shows a side view of a ceiling tripod DS according to the invention with a cable management module KM comprising a second cable reserve KR2 in a further embodiment in a position corresponding to a maximum height of the ceiling tripod DS. Fig. Figure 9 shows a side view of the ceiling tripod DS according to Fig. 8 in a position corresponding to a different operating height of the ceiling stand DS. In this version, the second cable reserve KR2 is formed via an energy chain EK or a guide tube, which runs in several, more precisely four, loops along the telescopic section TT. One attachment point AP is provided on the uppermost outer telescopic segment TS1, and another attachment point AP on the lowermost outer telescopic segment TS4. At least one further attachment point AP is arranged on the middle third telescopic segment TS3 in order to guide the second cable reserve KR2 during compression or extension of the telescopic section TT and, in particular, to ensure the correct formation of the loops when the telescopic section TT is compressed against the weight force on the second cable reserve KR2.

[0072] All connection points AP, especially the second cable reserve KR2, can each include a fixing clamp that allows a certain relative movement between energy chain EK or guide hose and telescopic segment TS1-TS4.

[0073] The execution of the second cable reserve KR2 also according to Fig. 8 or Fig. Figure 9 shows an arrangement of the second cable reserve KR2 offset laterally to the vertical axis VA, while maintaining the maximum rotation radius r. R before.

[0074] Unlike the execution of Fig. 1 includes the cable routing module KM of the Fig. 3 and Fig. 5 a first and a second cable reserve KR1, KR2, which are formed by means of a common energy chain EK. In the Fig. In the embodiment shown in Figure 3, the supply lines VL are therefore routed in an energy chain EK, which extends over the ceiling carriage DW and the telescopic section TT. This single energy chain EK enables both rotation around the vertical axis VA and movement of the telescopic section TT along the vertical axis VA.

[0075] The energy chain EK, forming the common first and second cable reserves KR1 and KR2, runs partly in the ceiling trolley DW and partly in the telescopic section TT. The section of the energy chain EK located in the telescopic section TT runs linearly along the vertical axis VA. There is a connection point AP located on the lowest outermost telescopic segment TS4 along the telescopic section TT.

[0076] In relation to Fig. 3. The energy chain EK is mounted so that it can slide along its length only via a funnel-shaped pivot bearing DL at the upper end of the telescopic section TT. When the telescopic section TT is extended, the energy chain EK slides into the telescopic section TT, and when the telescopic section TT is compressed, it is pushed upwards out of it. Compression or extension of the telescopic section TT is regulated in the Fig. 3 shown embodiment is supported by a cable spring pulley SFZ, with which a steel cable S, attached to the lowest outer telescopic segment TS4 and guided over a deflection pulley UR, is wound up or unwound.

[0077] Additionally, the energy chain EK maintains its linear shape along the length of the telescopic section TT solely due to its shear stiffness. Alternatively or additionally, a single guide element for the energy chain EK can be provided on at least one telescopic segment TS1-TS4, which, however, allows relative movement between the telescopic segment and the energy chain EK along the vertical axis VA.

[0078] The funnel-shaped rotary bearing DL, located in the ceiling carriage DW around the vertical axis VA, and the energy chain EK can simultaneously power the rotation of the telescopic section TT from the common cable reserve KR1, KR2. The common cable reserve KR1, KR2 is configured according to... Fig. The energy chain EK is stored in a second housing segment GS2, which is provided next to the actual ceiling trolley housing DWG in the form of housing segment GS1 when the cable length is not currently required. In the second housing segment GS2, the energy chain EK is fixed at its end via a connection point AP.

[0079] In this configuration, the energy chain EK now slides into and out of the second housing segment GS2 solely due to its shear stiffness, its weight, and, in particular, without any further guidance. In this configuration, the common cable reserve KR1, KR2, as well as the first cable reserve KR1, run in a different manner than in the configuration of the Fig. 1, in which the first cable reserve KR1 runs in a horizontal plane, in a vertical orientation.

[0080] The energy supply chain EK1-2 according to Fig. 3 has in particular a round cross-section, so that it can slide over the funnel-shaped rotary bearing DL from all directions depending on the current rotation angle of the telescopic part TT.

[0081] One particularly suitable for the design variant according to Fig. 3. Suitable design of a cable guidance module KM comprising a circular energy chain EK1-2 is in Fig. Figure 4 shows the energy chain EK1-2 in detail. It comprises a multitude of chain links KG arranged in series, each subdivided into three compartments. Each compartment accommodates a multitude of supply lines VL. Each compartment includes an opening slot ÖS for filling the compartment.

[0082] At the center of each chain link KG is a ball joint KGG, which serves to support an adjacent chain link KG. In their assembled state, the ball joints KGG form a cable guide SF at their center for the cable S of the cable spring tensioner SFZ, so that cable S and energy chain EK1-2 run together in a space-saving manner along the length of the telescopic section TT, similar to a zipper principle, and both run along the vertical axis VA.

[0083] In relation to Fig. 5. The energy chain EK is held in the overhead carriage DW via a winding mechanism AM in the form of a cable drum with a horizontal axis of rotation and is wound or unwound as needed. Additionally, the energy chain EK maintains its linear shape along the length of the telescopic section TT solely due to its shear stiffness. To compensate for any twisting of the cable strand that occurs during winding, a twister band (not shown) can be used.

[0084] In the ceiling trolley DW, one or more deflection rollers UR (not shown in detail) can be provided between the winding mechanism AM and the telescopic part TT in order to realize the required change of direction of the energy chain EK and / or to also in the version according to Fig. 5. To achieve a rotation of the telescopic section TT with the common cable reserve KR1, KR2 via the common energy chain EK. Alternatively or additionally, a single guide element for the energy chain EK can be provided on at least one telescopic segment TS1-TS4, which, however, allows relative movement between the telescopic segment TS1-TS4 and the energy chain EK along the vertical axis VA.

[0085] The shared cable reserve KR1, KR2 is implemented in the design of the Fig. 5 advantageously in the similarly cuboid ceiling trolley housing DWG space.

[0086] The embodiments of the ceiling stand DS according to the Fig. 1, Fig. 3 and Fig. What is common to 5 is that the respective cable management module KM includes a third cable reserve KR3, which is at least partially located in the telescopic section TT and / or in the medical device ME, in particular in the telescopic section housing TTG and / or the housing of the medical device MEG, and enables the medical device ME to be adjusted about the horizontal axis HA. A feature also found in the Fig. 1 and Fig. The preferred version of the third cable reserve KR3, already included in the 3, is incorporated into the Fig. 10, Fig. 11, Fig. 12 and Fig. 13 shown in detail and described below.

[0087] The Fig. Figures 10 to 13 each show the same configuration of the third cable reserve KR3, but always in a different position, specifically at a different angle of the medical device ME. In this configuration, the medical device ME is designed as an X-ray source or X-ray emitter. It has two high-voltage connections HV, which supply the voltage for generating the X-rays.

[0088] In this configuration, the third cable reserve KR3 runs vertically, specifically in a vertical plane. Similar to the first cable reserve KR1, the third cable reserve KR3 is formed by an energy chain with a reverse bending radius EKr, allowing it to be curved, at least partially, in two opposite directions, forming S-shapes or similar configurations. The curved path of the energy chain EKr provides a cable length sufficient for specific angular positions of the X-ray source.

[0089] The third cable reserve KR3 is in the Fig. The energy chain, with its rearward bending radius EKr, is connected via a rotating connection point AP close to or directly on the horizontal axis HA and fixed via another connection point AP near the housing. This second connection point AP can also be slidable along the inside of the X-ray housing. When the X-ray source is rotated around the horizontal axis HA, the energy chain EKr partially winds around the horizontal axis HA and, depending on the direction of rotation of the horizontal axis HA, changes from a horn shape to an S shape or vice versa, with changes in the direction of curvature.

[0090] In the Fig. Sections 14 to 18 describe further, alternative embodiments for the formation of the first and / or the third cable reserve KR1, KR3. Fig. Figure 14 shows a detailed view of a first and / or third cable reserve KR1, KR3 for a ceiling stand DS according to the invention in a further embodiment in a first position. Fig. Figure 15 shows this cable reserve KR1, KR3 in a different position. Fig. Figure 16 shows a detailed view of a first and / or third cable reserve KR1, KR3 for a ceiling stand DS according to the invention in a further embodiment in a first position. Fig. 17 and Fig. Figure 18 shows this cable reserve KR1, KR3 in a different position.

[0091] The cable reserves KR1, KR3 in the embodiments of the Fig. 14 to 18 are each characterized by a vertical orientation, with the cable reserve KR1, KR3 of the Fig. 14 and Fig. 15 are even arranged in a vertical plane. Alternatively, the orientation can also be horizontal.

[0092] In addition, the cable reserves KR1, KR3 of the Fig. 14 to 18 characterized in that they comprise a winding mechanism AM which runs around the horizontal axis HA or the vertical axis VA.

[0093] The cable reserve KR1, KR3 of the Fig. 14 and Fig. Furthermore, cable 15 runs in a loop or arc that is enlarged or reduced when a ceiling stand component is rotated around the enclosed axis, thereby providing or storing the required cable length. In the fully extended state, the U-shaped arc is at its largest, and the cable bundle or energy chain EK lies tangentially to the axis. In the retracted state, the cable bundle wraps around the axis depending on the angle of rotation. The necessary cable length is obtained from the U-shaped arc. The legs of the arc shorten as the cable is retracted, thus releasing the required cable length.

[0094] The Fig. Figures 16 to 18 show a spiral-shaped formation of the cable reserve KR1, KR3, as already seen in Fig. Figure 6 indicates the connection to the horizontal axis HA. The cable bundle is wound around the axis in a spiral shape. In the fully extended state, the cable bundle wraps around the axis approximately one to two times; in the retracted state, it wraps around the axis two to three times, depending on the angle of rotation. The cable length is stored for rotation by changing the diameter of the cable spiral.

[0095] The in the Fig. The cable reserve versions KR1, KR3 shown in 14 to 18 can each be housed either in the ceiling trolley housing DWG, in the telescopic partial housing TTG and / or in the housing MEG of the medical facility ME.

[0096] Regardless of the grammatical gender of a particular term, persons with male, female, or other gender identities are included.
