Description

Holding device for a medical apparatus, ceiling mount device and medical apparatus

Technical Field

The present invention relates to a holding device for a medical device, having a movement device for displacing the medical device with respect to a fixed accommodation of the holding device. The invention also relates to a medical device with such a holding device.

Background

Medical devices are known in the field of medical technology, which can be positioned in a room by means of a holding device. In particular, ceiling-mounted medical devices are known here, which are fastened to the ceiling of a room, in particular an examination room, via a ceiling mounting device. Such a medical device, in particular a ceiling-mounted medical device, can be, for example: a part of a C-arm X-ray apparatus in which an X-ray emitter (also referred to as X-ray emitter or X-ray tube) and an X-ray detector are fastened on a common, usually C-shaped carrier arm; or part of a radiological imaging device, wherein the X-ray radiator and the X-ray detector can be positioned substantially independently of each other. The X-ray emitter and/or the X-ray detector are fastened, for example, as a medical device, on the end side to a movement device of the ceiling mount device or the holding device. The movement device can in this case in particular comprise a telescopic element which can be moved out and in a telescopic manner and which in turn has a plurality of telescopic sections which are guided into one another in order to be able to adjust or displace the respective medical device in at least one adjustment or displacement or movement direction, in particular in a vertical direction. Non-imaging medical devices, such as, for example, devices for radiotherapy, can also have components, i.e. medical devices, which are fastened, for example, to corresponding holding devices or ceiling mount devices.

The movement device is usually embodied as a compact assembly which is provided only with space for the mechanical coupling mechanism and the drive of the movement device in its interior. Usually, however, medical devices must be connected to a large number of cables as electrical consumers of such medical devices, in particular X-ray emitters, apertures, collimators, drivers, sensors and/or detectors. The cable required for this purpose is guided in the known device via an externally located bellows

The bellows can however move in an undefined manner in the room when the movement device is adjusted, which could disturb the progress of the medical procedure. Since the movement of the cable guided in the bellows takes place largely in an undefined manner, increased wear is furthermore to be expected. Likewise, a correspondingly long cable reserve must be maintained with a large displacement or displacement range of the movement device, which results in a large space requirement of the bellows which is then in an undefined manner in the room, in particular in the moved-in state.

SUMMERY OF THE UTILITY MODEL

Based on this, the utility model provides an aim at as follows: the construction of a holding device for medical apparatuses is improved and in particular the cable guidance in such a holding device is simplified as follows.

The object is achieved by a holding device, a ceiling mounting device and a medical device. The invention is based on the object of providing an advantageous embodiment.

According to one aspect, a holding apparatus for a medical device is provided having a movement device for displacing the medical device. The holding device has a substantially shear-resistant cable guide for accommodating at least one cable. The cable guide has a first section and a second section, wherein the first section is designed such that the bending movement of the cable guide in the first section is substantially limited to a movement in a first plane, and the second section is designed such that the bending movement of the cable guide in the second section is substantially limited to a movement in a second plane, which is different from the first plane. Furthermore, the first section and the second section are each fastened individually to the movement device.

The holding device can be designed as a ceiling or floor support device, for example. The movement device can be configured such that it can displace the medical device in at least one displacement direction, wherein the displacement direction can correspond to a vertical direction.

Whenever reference is made to a shear-resistant cable guide mechanism, the phrase "shear-resistant" should be understood as follows: the cable guide mechanism is substantially shear resistant. Therefore, minor variations along the cable are not excluded by the wording of the accompanying specification. As long as it is said that the movement is limited to one plane, this should be understood as follows: the corresponding movement is substantially limited to movement in one plane only. Smaller deviations, i.e. smaller movements out of plane (if, for example, the first section and the second section are deformed in a direction perpendicular to the bending movement) are therefore possible and are encompassed by the words of the associated description. In other words, the first and second sections can each only be bent substantially in one direction. Depending on the embodiment, it can therefore be provided (in particular arranged on the movement device) such that the bending directions of the segments differ.

The term plane is used herein to describe the bending movement of the respective section of the cable guide mechanism and does not necessarily require that a corresponding plane is physically present in the holding device. In an alternative, the first section is designed such that the bending movement of the cable guide in the first section is substantially limited to a movement parallel to a first plane, and the second section is designed such that the bending movement of the cable guide in the second section is substantially limited to a movement parallel to a second plane (which is different from the first plane). The bending movement takes place here essentially in one plane only. However, the segments are not completely rigid with respect to out-of-plane deformation. The wording of the claims does not exclude that even out-of-plane deformations can be carried out when a force component acts on a first section or a second section perpendicular to a first plane or a second plane. In other words, the first and second segments are designed such that the bending or bending movement preferably takes place in or parallel to one plane when the end-to-end distance of the respective segment is shortened (in particular when no further forces are applied). The first and second sections are thus designed such that the bending deformation of the respective section takes place in a preferred direction, i.e. in or parallel to a plane.

In addition to the first and second sections, the cable guide can also have further sections, which are optionally likewise designed in such a way that they likewise limit the bending movement of the cable guide in the respective section to a movement in or parallel to one plane. In other words, according to the invention, a defined cable guide mechanism is provided, the deformation properties of which are distributed over a plurality of planes when the movement device is moved. The segments of the cable guide can be connected to one another, but this is not essential.

The segments are here fastened individually to the movement device. In other words, the segments are fastened to the movement device independently of one another, so that the spatial position of the segments relative to one another is at least determined together by the displacement state of the movement device. According to an embodiment, the segments are fastened to different segments of the movement device, respectively, which move differently and in particular relative to each other when the movement device is moved or displaced.

The movement device can be designed in particular for displacing a medical device placed thereon from a first position corresponding to the moved-in state of the movement device into a second position corresponding to the moved-out state of the movement device. The movement device can also be configured to displace the medical device into any position between the first position and the second position. The displacement of the medical device can take place here relative to a stationary part of the holding apparatus, which in particular supports the movement device.

The features of the holding device act synergistically as follows: an improved cable guiding mechanism is achieved. The shear-resistant design of the cable guide is therefore responsible, in particular, for the stress relief of the cable guided therein. In the retracted state of the running gear, the cable guide can have, in particular, a curved section in order to maintain the cable length required for the retracted state of the running gear as a so-called cable margin or cable reserve. In the extended state, the cable guide can in particular be substantially straightened (getterckt). The at least two segments enable a defined and compact arrangement of the cable tolerance around the movement device, to be precise in any position of the movement device. The assignment to different planes further improves the guidance or control of the cable guidance means, since the cable margin can be assigned to at least two sections, which further improves the control of the formation of the curved section. In particular, the excess of the cable guide in the retracted state can be reduced thereby. Furthermore, a compact cable guide mechanism can be achieved by the division into planes, the extension of which with respect to the sections of the movement device can be defined. This is supported by the individual arrangement of the segments on the movement device, since a good adaptation to the movement process of the movement device can thereby be achieved. In general, undefined interference edges of the cable guide can thereby be avoided for the user or patient and defined movements and loads of the cable reduce wear.

According to one aspect, the first plane and the second plane are not parallel to each other. In other words, the first plane and the second plane thus intersect. The directions in which the first and second sections can be bent thus differ from each other. This increases the flexibility of the arrangement and can, for example, allow a precisely fitting arrangement of the cable guide "around" the movement device.

According to one aspect, the first plane and the second plane are parallel to each other. This can for example mean that the first plane is in front of the second plane when the holding device is viewed with a line of sight towards the first plane. In other words, the first plane can be arranged on one side of the holding device, while the second plane is arranged on the opposite side. A defined arrangement of the cable guide can also be achieved by this arrangement.

According to one aspect, the movement device is configured for displacing the medical device in a displacement direction, and the first plane and the second plane intersect in a line parallel to the displacement direction. The movement device can be designed in particular such that a displacement of the medical device in the displacement direction is essentially the only degree of freedom of the movement device. In other words, the first plane and the second plane are thus substantially parallel to the displacement direction, but not parallel to each other. With this configuration, the cable margin can be compactly covered around the moving device.

Parallel to the displacement direction is to be understood here again as being substantially parallel to the displacement direction and including deviations from exact parallelism, which are unavoidable in practical implementations.

According to one aspect, the movement device has a telescopic part which can be moved telescopically out of and into and which comprises a plurality of telescopic sections, two telescopic sections each of which can be linearly displaced relative to one another. The first section is fastened to one telescopic section and the second section is fastened to another telescopic section different from the one telescopic section.

The telescopic section on which the section of the cable guide mechanism is fastened can be any telescopic section of a telescopic piece. In particular, a section of the cable guide can be arranged or fastened (in the case of a corresponding number of sections of the cable guide) on each telescopic section. The sections of the cable guide can also be arranged on the movable telescopic sections in each case. The movable telescopic section is in particular a telescopic section that is not fixed relative to the receptacle of the holding device. In this case, a section (e.g., the second section) of the cable guide can be arranged in particular on the last telescoping section on which the medical device is arranged. According to a further embodiment, a section of the cable guide (for example the first section) can however also be provided on the telescopic section which is fixed relative to the holding device.

The telescopic section can, for example, comprise tube sections which are respectively guided in one another in order to be able to adjust or displace the medical device in a displacement or displacement direction. The guidance of the individual telescopic tube sections can take place, for example, via running rollers arranged between the tube sections. According to a further embodiment, the telescopic sections can be designed as profile rails which can be adjusted relative to one another by means of a profile rail guide system.

By associating the sections of the cable guide with telescoping sections by placing the sections of the cable guide on the corresponding telescoping sections, it is in principle possible to associate each telescoping section with a plane, which enables a defined cable guide.

According to one aspect, the first plane is perpendicular to the second plane. It is to be understood here that the planes are substantially perpendicular to one another and that, in practical implementation, unavoidable deviations from a precisely perpendicular configuration are included in the choice. In other words, the first plane thus encloses a substantially right angle with the second plane. The cable guide can thereby be formed particularly compactly around the movement device. Furthermore, a misalignment in the bending direction between the segments can thereby also be limited, which reduces cable stresses.

According to one aspect, the first section is designed such that the bending radius achievable during the bending movement of the first section is limited to a minimum bending radius. In addition or alternatively, the second section can also be designed such that the bending radius achievable during the bending movement of the second section is limited to the (minimum) bending radius. Cable loads can be further reduced by limiting the bend radius.

According to one aspect, the first section and/or the second section is designed as an energy guiding chain.

Other expressions for the energy guiding chain include an energy chain, an E chain or a drag chain. The energy guiding chain comprises a plurality of chain links which form a longitudinal section for guiding the cable or line. The links are connected to each other via hinges, the hinge axes of which run, for example, parallel to each other. If the first section is designed as an energy-guiding chain, the hinge axes are correspondingly (substantially) perpendicular to the first plane. If the second section is designed as an energy-guiding chain, the hinge axes are correspondingly (substantially) perpendicular to the second plane.

The energy guiding chain can be embodied as an open or closed energy guiding chain. The closed energy guide chain completely encloses the line guided therein, the cable guided therein or the line or cable guided therein. In the case of open-chain energy guiding, there are material interruptions, so that the wires/cables guided therein are generally not completely enclosed in the circumferential direction of the energy guiding chain. The energy guiding chain is generally designed to be shear-resistant and compliant and defines a minimum bending radius for the cable guided therein, so that no undefined cable movements occur. The energy guiding chain is particularly suitable for reducing mechanical stresses acting on the cable.

According to one aspect, an end of the first segment is connected to an end of the second segment. By connecting the first section to the second section, the freedom of the cables and lines guided in the cable guide can advantageously be further limited. On the other hand, the kinematics of the bending movement of a segment can be transferred to the connected segment and vice versa. This is responsible for a smooth transition without misalignment between the sections, which further reduces the material load of the guided cable/line.

According to one aspect, the first section and the second section are connected to each other via a connecting section. According to one embodiment, the connecting section can be designed such that it completely or partially encloses the lines and/or cable elements guided in the connecting section. According to an embodiment, the connecting section can be substantially rigidly designed and does not allow a bending movement. For example, the connecting section can be designed as a pipe element. This ensures that the change in direction of the bend between the first section and the second section is carried out as smoothly as possible and thus without a large load on the guided cable/line. According to one embodiment, the connecting section can be formed in a flexible manner, for example in the form of a bellows, which can be bent essentially, in particular in all directions. This embodiment makes it possible to adapt the cable guide to the movement device more flexibly. According to a further embodiment, the connecting section can also have two substantially rigid sections in order to establish a connection with the first section or the second section of the cable guide mechanism, respectively. The rigid section can then be connected to the substantially flexible section in order to combine the advantages of the above-described embodiments. According to a further embodiment, the connecting section can also be designed in an articulated manner such that it supports the bending direction of the first section and the bending direction of the second section. This can be achieved, for example, via a ball-and-socket joint design or by means of an element having two hinge axes which are arranged in correspondence with different bending directions of the first and second sections of the cable guide (i.e. one hinge axis is perpendicular to the first plane and the other hinge axis is perpendicular to the second plane).

According to one aspect, the second section follows the first section in the travel path of the cable guide mechanism. Optionally, the first section and the second section are not connected to each other here. In other words, then there is a section between the first section and the second section: the bending movement in this segment is not limited to a movement in one plane/in one bending direction. This can be advantageous in the following cases: greater flexibility is desired between the sections, for example to achieve a better match to the kinematics of the movement device. The cable/line can in particular run freely in this section.

According to one aspect, the cable guide mechanism further has at least one third section, wherein the third section is designed such that a bending movement of the cable guide mechanism in the third section is substantially limited to a movement in a third plane, wherein the third plane is not parallel to the first plane and/or not parallel to the second plane.

The one or more third sections can be modified with the features explained with reference to the first section and/or the second section, respectively. The advantages described in this context can correspondingly also be realized for one or more third sections. The third section can be designed in particular as an energy guiding chain. By adding a further section, the cable run can be further defined and adapted to the movement of the movement device as required.

According to one aspect, the cable guide mechanism has a length that is greater than a maximum displacement path of the motion device. The first portion and/or the second portion can each have a length which is less than the maximum displacement path of the movement device. This makes it possible to provide sufficient cable margin on the one hand. On the other hand, cable tolerances can be suitably distributed, so that cable bends are formed in a defined and low-disturbance manner.

If a telescopic element is used as the movement device, the length of the sections of the cable guide can be designed such that the sections of the cable guide are longer than one telescopic section, but shorter than two telescopic sections. Preferably, the section of the cable guide is approximately one and a half as long as the telescopic section, wherein it is assumed that all telescopic sections have the same length. According to some embodiments, the lower end of the cable guide can be fastened or fixed to the lowermost telescopic section. The lowermost telescopic section is the following telescopic section: below the telescopic section, in the extended state of the telescopic part, no further telescopic section is followed and in particular a medical device is fastened to the telescopic section. The cable guide is preferably fixed or fastened by its lower end to the upper end of the lowermost telescopic part. Alternatively or additionally, the upper end of the cable guide, i.e. the end opposite the lower end of the cable guide, can be fastened or fastened to the uppermost, fixed telescopic section. The uppermost telescopic section is a telescopic section provided opposite to the lowermost telescopic section at the other end of the telescopic member. The telescopic section is fixedly formed. In other words, it is provided, for example, on a ceiling slide or on a room ceiling, such that the telescopic section itself cannot be adjusted in the vertical direction.

The fixing or fastening point for the cable guide on the movement device can be selected such that the movement of the movement device, in particular toward the retracted state, is not impaired.

In an embodiment, the sections of the cable guide can be fixed or fastened on the respective fastening points by means of a suspension that is rotatably and/or linearly displaceable along the movement means (respective telescopic sections), respectively. This makes it possible to advantageously support the degrees of freedom of the cable guide during movement of the movement device without giving up control of the bending movement of the cable guide. Furthermore, the provision of a linear cable guide suspension along the path of movement of the movement device makes it possible to achieve a cable length which is to be maintained for the extended state of the movement device, which is advantageously of small design, which saves material costs and space and simplifies the construction of the holding device.

According to one aspect, the holding device can be designed as a ceiling mount and the movement device is designed for displacing the medical device in the vertical direction.

According to one aspect, the holding device can also have a running carriage or ceiling carriage in which the movement means are supported. The movement device can be mounted in particular rotatably here.

According to another aspect, a ceiling mount apparatus for a ceiling supported medical device is provided. The ceiling mount apparatus has: a telescopic part which can be moved out of and in a telescopic manner in a displacement direction (in particular in a vertical displacement direction) and which has a plurality of telescopic sections, two telescopic sections of which are each displaceable relative to one another; and a substantially shear resistant cable guide mechanism for receiving at least one cable or wire. The cable guide has a first section and a second section. The first section is designed such that the bending movement of the cable guide in the first section is substantially limited to a movement parallel to the first plane, and the second section is designed such that the bending movement of the cable guide in the second section is substantially limited to a movement parallel to the second plane. Here, the first plane and the second plane extend substantially parallel to the displacement direction (optionally the first plane and the second plane intersect in a straight line substantially parallel to the displacement direction). Furthermore, the first section is disposed on a first telescoping section and the second section is secured on a second telescoping section different from the first telescoping section.

The advantages and improvements described more hereinabove can be similarly transferred to the above aspect where compatible.

In a further aspect, a medical device is provided, which is in particular designed as an imaging device and has a holding device or a ceiling mount device according to the invention. The medical device can thus be configured with a medical apparatus that is movable by means of the movement apparatus. The medical device can be designed in particular as a ceiling-mounted device. The medical device can be implemented, for example, as a stand-alone unit or as part of a larger medical system, in particular a radiology system.

In one embodiment, the medical device is part of an imaging radiology system. Preferably, the X-ray radiator is arranged at the end face on the movement device (or on the telescopic part). The X-ray radiator can be set in different, in particular vertical, positions, in particular by means of a movement device (or by means of a telescopic element which can be telescopically moved in and out). In one embodiment, the movement device or the telescopic element additionally carries an aperture unit, a display and/or an operating element for detecting user-side inputs and/or for positioning the X-ray emitter or the aperture unit. For the detection of the fluoroscopic images, the radiology system comprises in a configuration at least one X-ray detector, which can be positioned in particular independently of the X-ray emitter. For example, the X-ray detector is integrated in an examination table or fastened to a wall or floor support. In a further embodiment, the X-ray detector can be supported and in particular fastened to the ceiling of the examination room by means of a holding device or ceiling mount device already described above. In one embodiment, a plurality of X-ray detectors can be provided, which are respectively integrated in the examination table and/or fastened to the holding device or the ceiling mount device. In a further embodiment, the at least one X-ray detector is arranged on a mobile unit that can be moved freely and in particular autonomously in the examination room.

The medical device and/or the radiology system comprise, for example, a control device having a system control and/or a generator for supplying a high voltage, in particular for at least one X-ray radiator. In a refinement, the medical device and/or the radiology system further comprises at least one display unit, such as, for example, a display or a monitor, in particular for displaying image data of the detected examination region. The display of the image data relates, for example, to the display of projection images or of slice images composed of three-dimensionally reconstructed image data sets. In one embodiment, the medical device and/or the radiology system has at least one evaluation unit and/or at least one processor for executing at least one program or at least one software, in particular for image evaluation, or for executing at least one control routine. For image detection and/or image evaluation, in one embodiment at least one human-machine interface or user interface is preferably provided for detecting user inputs. In a possible embodiment, the man-machine interface comprises, for example, a plurality of user-side activatable switching elements or keys or a display (touch screen) with a touch-sensitive surface.

Detailed Description

Fig. 1 shows a holding device 1 or ceiling mount device 1 for a medical apparatus 100, which in the exemplary embodiment shown comprises an X-ray emitter-collimator unit, which is arranged at the end on a movement device 10. In the embodiment shown, the movement device 10 is designed as a telescopic element 10 which can be moved in and out telescopically in the vertical direction.

The holding device 1 or the ceiling mount device 1 can be movably guided in a horizontal plane by means of the bearing units 30, 40, so that the medical apparatus 100 can be positioned substantially freely in the room. The bearing units 30, 40 can additionally or alternatively be designed to bring about a rotation of the entire movement apparatus 10 about the vertical axis of the movement apparatus 10, for example in order to achieve a corresponding orientation of the medical apparatus 100. The medical device 100 can also be mounted pivotably on the end of the movement apparatus 10, so that the orientation of the medical device 100 can be preset in this respect independently of the position or position of the movement apparatus 10.

The medical apparatus 100 is, for example, part of an imaging radiation system, which comprises at least one X-ray detector for detecting a fluoroscopic image of a patient. The exemplary, in particular ceiling-mounted, X-ray emitter-collimator unit 100 is designed, in particular, to be positioned and oriented with respect to an X-ray detector, which is integrated, for example, in an examination table or fastened to a wall mount or to another holding device 1.

The telescopic part 10 shown as an example as a movement device 10 comprises a plurality of telescopic sections 11 guided in or on each other. In the exemplary embodiment shown, four telescoping sections 11 are provided. This is only an exemplary and not limiting number of telescopic sections 11. The first, uppermost telescopic section 11 can be designed as a fixed, i.e. vertically non-adjustable, linear rod or profile element. The uppermost telescopic section 11 thus forms a receiving structure for the further telescopic sections 11. The individual telescopic sections 11 can be mounted in a manner that can be pushed or moved relative to one another by means of a profile rail guide system. The telescopic section 11 can be designed in particular as a U-shaped profile, which forms a vertically extending cavity in its interior, which is designed to accommodate technical components for vertical movement. In the case of U-shaped profiles, planar baffle elements (not shown) in the form of covers can be provided in each case according to some embodiments, which can be fastened over the openings on the longitudinal sides of the respective profile in order to close the profile. Thereby avoiding accidental intervention and the associated risk of pressure loss.

Alternatively, one or more of the telescopic sections 11 can be designed as a round, rectangular or square tube element in profile, which can likewise have a cavity extending in the vertical direction in its interior, which is suitable for accommodating technical components for vertical movements.

The medical device 100 is placed on the lower end of the lowermost telescopic section 11. The medical apparatus 100 is preferably mounted rotatably or pivotably, more precisely in particular about a horizontal axis, so that if the medical apparatus 100 comprises an X-ray collimator unit, for example, it is possible to illuminate not only flat X-ray detector positions but also vertical X-ray detector positions.

The medical apparatus 100 can be supplied with energy or process fluid via one or more cables or lines and/or be in signal connection with a control unit, not shown. The cable or line is arranged in the cable guide 20 at least as long as it extends outside the movement device 10. As shown in fig. 1, the cable or line can, for example, first run in the uppermost telescopic section 11 and exit from the uppermost telescopic section 11 at an exit point 11 a. The exit point 11a can be selected such that cable extension inside the uppermost telescopic section 11 does not impair the displacement or displacement movement of the telescopic element 10. The cable guide 20 can be connected directly to the exit point 11a and via the exit point 11a to the interior of the uppermost telescopic section.

The cable guide 20 in the illustrated embodiment has two sections 21 and 22, which follow one another in the direction of travel of the cable towards the medical device 100. The illustrated embodiment with two sections 21 and 22 is merely exemplary and should not be understood as limiting. Thus, the cable guide 20 can also have more than two and in particular three, four or five such sections. The cable guide can in particular have as many sections as the telescopic part 10 has the telescopic section 11.

The segments 21 and 22 are designed as energy guiding chains. The energy-guiding chains each comprise a plurality of links which are connected to one another in an articulated manner and which each accommodate a longitudinal section of the cable guided therein. The chain links are hingedly connected to each other via hinge axes, wherein the hinge axes of the energy chains/sections run parallel to each other. Due to this arrangement, the energy guiding chain can usually be bent significantly in one direction only and is substantially resistant to bending in the other direction. In other words, the bending movement of such an energy guiding chain is limited to a movement in or parallel to the plane to which the hinge axes of the energy guiding chain are perpendicular. In the embodiment shown, the two energy guiding chains are now combined such that the direction of bending differs in the two sections 21 and 22. In other words, the articulation axes of the energy guiding chains of the sections 21 and 22 are therefore not parallel to each other. The first section 21 is therefore designed such that the bending movement of the cable guide 20 in the first section 21 is substantially limited to a movement in a first plane E1, while the second section 22 is designed such that the bending movement of the cable guide 20 in the second section 22 is substantially limited to a movement in a second plane E2, the second plane E2 being different from the first plane E1. Thereby, the bending movement of the cable guide 20 in the first section 21 can be kinematically separated from the bending movement of the cable guide in the second section 22, which enables a defined guidance and good control of the cable and the line connection towards the medical device 100. It should be noted here that the illustrated embodiment shows possible variants by means of an energy guiding chain: how to provide a kinematic separation of the sections of the bending movement of the cable guide means 20. A similar action can be achieved, for example, by means of a bellows which is reinforced perpendicularly to the intended bending direction or by a combination of fastening elements and/or geometric guide elements or guide surfaces.

The sections 21 and 22 of the cable guide 20 are arranged on the movement device 10 separately and in particular independently of one another. In the embodiment shown, the first section 21 is fastened, for example, on the uppermost telescopic section 11 at the departure point 11 a. The fastening point 11a thus coincides with the departure point 11a in the embodiment shown. This is to be understood only by way of example, however, and the fastening point can also be different from the exit point in alternative embodiments, or the exit point can be dispensed with if the cable/line runs completely outside the movement device 10. The fastening in the fastening point 11a can be designed here with corresponding receptacles, so that the first section 21 is completely fixed in the fastening point 11a, so that no freedom of movement remains in the fastening point 11 a. Such a receptacle can be designed in particular such that the first portion 21 cannot be rotated about the fastening point 11a, so that the exit direction of the cable guide 20 is defined from the exit point 11a (in the example shown, vertically upwards). This can reduce the load of the cable/line guided in the cable guide mechanism when the moving device 10 is displaced.

In the example shown, the second section 22 is fastened to the fastening point 11b at the third telescopic section 11 viewed from above. The fastening of the second portion 22 to the movement device can be designed by means of corresponding receptacles in such a way that the second portion 22 can be rotated in the fastening point 11b relative to the movement device 10 about an axis A1, which axis A1 is perpendicular to the second plane E2. In addition or alternatively, the receptacle can be designed such that the fastening point 11b can be moved, in particular linearly, relative to the movement device 10, to be precise essentially in the plane E2 or parallel to the plane E2. The fastening can be configured, for example, such that the fastening point 11b can be moved in the vertical direction R along the third telescopic section 11. Alternatively or additionally, the second section 22 of the cable guide 20 can be mounted directly on the medical device 100, in particular at one end of the second section 22 (in particular such that a rotation about a fastening point there is possible).

The configuration shown and described of how the sections 21 and 22 of the cable guide 20 are arranged at the movement device 10 is to be understood merely as an example. In particular, the section 21 or 22 can therefore also be arranged on more than one telescopic section 11. Alternatively or additionally, the section 21 or 22 can also be placed on the telescopic section 11 by means of a plurality of fastening points. The fastening of the second section 22 of the cable guide can also be designed such that a freedom of movement relative to the movement device 10 is not possible in the fastening point. Conversely, the first section 21 can also be fastened to the movement device 10 in such a way that the one or more fastening means allow a rotational movement about the fastening point in the plane E1 or parallel to the plane E1 and/or a displacement of the fastening point in the plane E1 or parallel to the plane E1.

As shown in fig. 1, the two sections 21 and 22 can be connected to one another at their ends in each case, so that a continuous guidance of the cable/line accommodated in the cable guide 20 is ensured. The connection between the sections 21 and 22 can be brought about by the connecting section. The connecting section can be constructed rigidly or flexibly and in particular in an articulated manner. According to an alternative, not shown embodiment, the segments 21 and 22 can also not be connected to one another. The cable accommodated in the cable guide 20 can then run more or less freely between the sections 21 and 22.

The length of the sections 21 and/or 22 can be selected in particular such that the overall length of the cable guide 20 is divided over the two sections 21 and 22. In other words, the sections 21 and/or 22 can each have a length that is shorter than the overall length of the cable guide 20. Depending on the fastening points 11a, 11b and the type of fastening of the segments 21 and 22 on the movement device 10, the length of the segments 21 and 22 can be selected in particular such that sufficient margin is available in order to follow the movement of the movement device 10 from the completely moved-in position into the completely moved-out position.

Fig. 2 to 4 show different displacement states of the movement device 10. Fig. 2 shows the retracted state of the movement device 10, while fig. 4 shows the extended state of the movement device 10. Fig. 3 shows an intermediate state of the movement device 10.

The length of the sections 21 and/or 22 can be selected such that, taking into account the fastening points 11a, 11b on the movement device 10 and/or the type of fastening in the fastening points 11a, 11b and/or the minimum bending radius, the respective sections 21, 22 can overcome the relative movement of the components/sections 11 of the movement device 10 when the movement device 10 is moved without being damaged.

. At the same time, the length of the sections 21 and 22 can be selected such that as little excess length margin as possible is maintained, which saves material and enables a compact, i.e. less disturbing, cable guide mechanism. In the example shown in fig. 2 to 4, the length of the sections 21 and/or 22 is therefore longer than the length of the telescopic section 11, but shorter than the length common to both telescopic sections 11 (in the state of the movement device 10 moved out of each other).

In the inserted state of the movement device 10, which is shown in fig. 2, the sections 21 and 22 each extend in a curve in the planes E1 and E2 defined by the sections 21 and 22 according to the embodiment of the invention. The spatial extent of the curve in the respective plane E1 and E2 can then be influenced or set by the minimum bending radius of the section 21 or 22 and/or by the position of the fastening point 11a, 11b or the type of fastening of the sections 21 and 22 on the movement device 10 in the fastening point 11a, 11 b. The bend forms a length allowance of the cable guide mechanism 20.

If the movement device 10 is displaced from the moved-in state into the moved-out state, the bends formed in the sections 21 and 22 become smaller but remain in the respective plane E1 or E2 (see fig. 3 and 4). The cable guide 20 can thus follow the movement of the movement device 10 without uncontrolled movements, in particular bending movements, of the cable guide 20 occurring. In a pictorially speaking, when the movement means 10 move, the sections 21 and 22 roll annularly in the planes E1 and E2 so as to release or accommodate the length allowance. In the extended state (see fig. 4), at least one of the segments 21, 22 can straighten more or less. In this case, possible still existing bends or bending deformations also extend in the respective planes E1 and E2. If the movement device 10 is moved into the retracted state again, the bending movement for accommodating the length allowance of the cable guide 20 in the sections 21 and 22 takes place again in the respective planes E1 and E2.

Fig. 5 shows a view of a medical device 200, in particular in the form of a medical imaging facility or an X-ray imaging facility, together with a holding device 1 according to one embodiment in the form of a ceiling mount device 1. The medical apparatus 200 is provided in an examination room in, for example, a hospital. The ceiling mount arrangement 1 can comprise a ceiling-mounted rail system 30, by means of which a travelling carriage 40 can be adjusted in the x or y direction below the ceiling of the room. At the travel carriage 40, the movement device 10 is provided, for example, in the form of a telescopic element 10. At the lower, preferably lowermost, telescopic section 11 of the telescopic element 10, a medical device 100 is provided, for example in the form of an X-ray radiator 100. The telescopic element 10 is designed to adjust the X-ray emitter in the z-direction, i.e. in the vertical direction R. The X-ray emitter 100 is also mounted on the telescopic section 11 in such a way that it can be rotated about the z-axis either together with the telescopic section 11 or independently of the telescopic section 11. Furthermore, at least one horizontally extending rotational axis is provided through the X-ray emitter 100 or at least at the level of the X-ray emitter 100 in order to be able to tilt or tilt the X-ray emitter 100. By providing a plurality of different degrees of freedom, the X-ray radiator 100 can be placed as best as possible in the position required for the image data detection.

The holding device 1 can also comprise a drive unit 50 in order to adjust the X-ray radiator 100 with at least three spatial degrees of freedom. The holding device is designed to adjust different movable components of the holding device 1 or of the X-ray emitter 100 with different degrees of freedom. The drive unit 50 can here comprise, for example, at least one drive module (e.g. an electric motor), a brake and a sensor, wherein the drive module acts on at least one of the movable components of the holding device 1 via a mechanical coupling mechanism known per se.

The holding device 1 further comprises a control unit 60, which is in this case designed as a submodule of the computing unit 201 of the medical device 200. The control unit 60 is configured to control the displacement movement of the X-ray irradiator 100 by generating control signals for the drive unit 50. Not only the computing unit 201, but also the control unit 60 can alternatively be provided remotely or remotely from the holding device 1 or the medical device 200, for example as part of a central computing and control unit of a hospital. The data exchange can take place wirelessly. The calculation unit 201 and/or the control unit 60 can be designed in the form of hardware or in the form of software. For example, the control unit 60 is configured as a so-called FPGA (abbreviation for "Field Programmable Gate Array" in english) or includes an arithmetic logic unit.

While the details of the present invention have been illustrated and described in detail with reference to the preferred embodiments, the invention is not limited thereto. Other variants and combinations can be derived therefrom by those skilled in the art without departing from the basic idea of the invention. The cable guide can in particular also have more than the two sections 21 and 22 shown in fig. 1 to 4. For example, the cable guide can also have three, four, five or more sections, which can be designed such that the bending movement of the cable guide in the respective section is substantially limited to one movement each in one plane. The planes can then in particular differ from the first or second plane E1, E2, respectively. Such further planes can be parallel to the first plane E1 and/or the second plane E2. Such further planes can intersect the first plane and/or the second plane in particular in a straight line which can be parallel to the displacement direction R of the movement device 10 in particular. Further, the cable guide mechanism 20 can also have the following sections: the bending movement of the segments is not limited to one plane, as for example a bellows, an energy guiding chain bendable in multiple directions, etc.
