Description

Guide device for line routing device with line routing device

The invention relates to a guiding device for a line guiding device comprising such a line guiding device according to the preamble of claim 1 and a device or a machine with such a guiding device according to the preamble of claim 15.

The generic guiding device has a C-shaped guiding area for guiding the line guiding device, so that the line guiding device is also arranged in its longitudinal extension in a C-arc shape on the guiding device. Such guide devices are used, for example, in C-arm X-ray machines or other medical diagnostic devices. At the opposite end regions of the C-arc shaped guide region of the guide device or extension of the same are usually a signal-emitting device such as an X-ray tube on the one hand and a signal-receiving device such as a detector, for example as an image amplifier or imaging system, or other corresponding consumers for of Media transmitted to the lines, is arranged. The guide device is here usually arranged on a holder of the device or machine comprising it, the holder being arranged, for example, on the outside of the curvature of the C-arc-shaped guide region of the guide device. The guide device is usually opposite in its longitudinal direction the holder can be moved, the holder generally engaging locally with respect to the longitudinal extent of the guide device, that is to say extends only over a relatively small longitudinal extent area of the guide device. When the guide device is moved, it thus describes an envelope in relation to the axis of curvature of the C-arc-shaped guide region; in the case of the guide region being designed as a circular arc segment, a cylindrical surface is thus circumnavigated in its circumferential direction. As a result, an object arranged in the center of the C-arm-shaped guide area, such as a patient, for example, can be examined from several directions without changing its position. These statements on a generic guide device and / or on the device or machine can also be implemented in relation to the subject matter of the invention, provided that they do not contradict the description of the same.

There is now the need to expand the extension of the C-arcuate guide area of the guide device so that it extends over a larger angular extent or angle of rotation around the axis of curvature of the arc, and / or the C-arcuate guide area over a larger one Angular range around the axis of curvature, ie in order to be able to move a greater distance in the longitudinal extent of the C-arc-shaped guide area, in particular in the direction of the installation surface of the device or machine comprising the guide device. However, this leads to various problems with gat device according to devices. On the one hand, in previously known guiding devices in which the line guiding device is cantilevered angeord net and the upper and lower strands of the line guiding device are arranged one above the other and at a distance from one another in relation to the direction of gravity, the cantilevered length is too large if the expansion of the C. -arrow-shaped guide area is enlarged. This leads to Upper and lower run come into contact with one another in areas, which significantly affects the smoothness of the line guide device and can lead to increased abrasion. On the other hand, the deflected line guide device, in which the upper and lower strand are arranged concentrically with respect to the axis of curvature of the C-shaped guide region of the line guide device, occupies a considerable overall height. However, this often restricts the movement of the guide device towards the installation surface of the device or machine comprising the guide device, which thus limits the area of application of the device or the machine.

The invention is based on the object of improving a generic guiding device or device or machine with such a feature that the C-shaped guiding area of the guiding device can be moved over a larger angle of rotation about its axis of curvature, possibly even in confined spaces with respect to the ground clearance of a device or machine comprising the guiding device and, even with a relatively large length of the line guiding device, smooth running is given.

This object is achieved by a guiding device with a line guiding device according to claim 1 or by a device or machine according to claim 15 comprising these. Advantageous embodiments emerge from the subclaims.

According to the invention, the guide device has a deflection device with a deflection axis, which is arranged on the Umlenkbe rich of the line guide device and around which the deflection area of the line guide device is guided. In this case, the deflection device preferably couples to the deflection area on the inside. This is in various or preferably all of the displacement positions of the line routing device, the deflecting device is arranged in the order of the deflecting area of the line guiding device and the line guiding device is deflected around the deflecting device, that is to say lying against it in the deflecting area. Furthermore, the deflection device is arranged in such a way that the axis thereof encloses an angle with the axis of curvature of the C-arc shaped guide region of the guide device, that is, an angle not equal to 0 °, that is, inclined or preferably transversely to this. Furthermore, the line routing device is arranged in such a way that one of the side boundaries thereof faces the concavely curved outside of the curvature of the C-arm-shaped guide region. The side boundary of the line guide device represents a preferably continuous Seitenbe limitation of the upper and lower run and the deflection area of the line guide device and thus extends transversely or in particular perpendicular to the facing surfaces of the upper and lower run. The guiding device determines the position of the line guiding device in relation to its longitudinal alignment by guiding the same.

The line guide device is guided in a C-arc shape with respect to its longitudinal extension through the C-arm of the guide device.

Due to the construction according to the invention, a particularly low overall height of the line guide device or dersel ben together with the guide device is given, since the line guide device with upper and lower run, so to speak, in relation to the guide area of the C-arm of the guide device - in contrast to a conventional one order - is "laid on its side", since the line guiding device is arranged with one of the side boundaries facing the C-arm of the guiding device. The height here is the height in the radial direction to the axis of curvature of the C-arm - Approximation device can be moved further in the direction of the installation surface of the device or the machine or the movement is not hindered by the installation surface. The subdivision area is usually the floor of a room, that is, the room of a building.

Furthermore, the arrangement of the deflection device in the deflection area of the line guiding device, which is thus preferably always arranged in the deflection area of the line guiding device even with different movement positions of the line guiding device and the line guiding device is guided around the deflecting device, ensures a comparatively tight and stable guidance of the line guiding device given, which thus in particular prevents that even with large circumferential extensions of the C-arm of the guiding device or with long lengths of the line guiding device, the upper and lower strands of the line guiding device come into contact with each other and thereby disturb the smoothness when moving the line guiding device.

In general, within the scope of the invention, the C-arm-shaped guide area of the guide device is abbreviated as “C-arm of the guide device” or “C-arm”. In general, within the scope of the invention, “Umlenkbe rich” is understood to mean a deflection area of the line routing device.

The axis of curvature of the C-arm thus corresponds to the axis of rotation of the C-arm. The axis of curvature is thus in the center of the C-arm. In the case of a circular arc-shaped C-arm, the axis of curvature or rotation thus correspond to the center point axis of the C-arm, which is thus angeord net in the center of the C-arm and perpendicular to the main axis of the C-arm. The line routing device can be designed, for example, as a link chain, as is the case with energy supply chains, in which a large number of individual chain links are articulated and adjacent links can be pivoted about a pivot axis, this pivoting resulting in the spatial deflection. Such chain links consist mostly of two laterally spaced apart Be tenteilen and an upper web and lower web, which together define the inner cross-section of the line routing device. The side parts and transverse webs can each be designed as individual components or can be connected to one another in one piece, for example with the formation of a U-shaped part comprising a transverse web and two molded-on side parts or the like. The chain members are here preferably pivotable about a joint axis formed by the joint elements of the same, but without being restricted to this. For example, the individual chain links of a line guide device can also be articulated to one another by articulated connections in the manner of a ball joint or in some other way. The line routing device can be designed, for example, as or in the manner of an articulated pipe with a plurality of pipe sections articulated to one another. The line guide device can, however, generally also be formed in one piece or comprise several longitudinal sections, each having a plurality of laterally spaced pairs of side tabs or lateral boundaries of the inner cross-section and thus also of the line guide device itself. For example, U-shaped chain links can be provided with an openable or subdivided crossbar, which is detachably fastened to a tape extending over the entire length of the line guide device or integrally formed thereon. Said endless belt can additionally also have the function of transverse webs and the inner cross-section or receiving space of the Limit line routing device, wherein the side parts of sections of the line routing device can also be molded directly onto the endless belt. The line routing device can, for example, also be designed as a deformable pipe or hose, for example also slotted pipe or hose, the desired flexibility or bendability of the line routing device being provided by the slots or other corresponding material recesses or material weaknesses, whereby the flexibility or flexibility, a spatial deflectability of adjacent sections of the line routing device is formed. The "deflectability" of the sections of the line routing device is therefore generally not limited within the scope of the invention to the formation of specially defined joint areas between said sections. The spatial deflectability is therefore generally given within the scope of the invention in each case perpendicular and / or transversely to the longitudinal direction of the line routing device, where "perpendicular" is understood here in the direction of the upper run to the lower run or vice versa. The adjacent, mutually spatially deflectable sections of the line guide device are thus generally preferably spatially deflectable to each other by at least two directions at an angle to each other, the directions preferably being perpendicular to each other.

The line routing device can, for example, have a circular cross-section, that is to say, for example, have the shape of a tube with a circular cross-section, or a rectangular cross-section, without being restricted thereto.

The guide device according to the invention is particularly preferred when the axis of curvature of the C-arm of the guide device is at an angle of 30 ° -150 °, preferably 45 ° -135 ° or in particular 60 ° -120 °, particularly preferably about 90 ° is arranged to the direction of gravity. The direction of gravity is usually at the same time the Z-direction of a room on the device or machine comprising the guide device. The advantages according to the invention are then particularly evident.

The axis of the deflection device, in particular in the form of a deflection roller, and thus also the deflection axis of the deflection area of the line guide device, is preferably at an angle of 30 ° -150 °, or 45 ° -135 °, preferably at an angle of 60 ° -120 °, particularly preferably arranged at an angle of approximately 90 ° to the axis of curvature of the C-arm of the guide device. This results in a stable spatial position of the line guide device with its arrangement on the C-arm of the guide device, the line guide device being "laid on its side" with respect to the guide surface of the C-arm Furthermore, this results in a comparatively low overall height of the line guide device and thus also of the guide device that encompasses it. This is particularly the case if the axis of curvature of the C-arm is at an angle to the direction of gravity or .Z-axis of the installation space of the device or machine comprising the guide device, in particular when the axis of curvature of the C-arm is arranged transversely or preferably at 90 ° to the direction of gravity.

The C-shaped guide area of the guide device preferably extends over> 50% or> 75%, preferably over> 85% of the longitudinal extent of the line guide device, more preferably over the entire length of the line guide device. As the "entire longitudinal extension" of the line routing device, let the length thereof in a travel state or arrangement of the lines Line routing device understood with the maximum distance between the two opposite ends of the same, that is, for example, when the two connection devices at the two opposite ends of the line routing device are at a maximum distance from one another. As a result, the line guide device can be adapted over its entire length to the shape of the C-arm of the guide device and is preferably also guided through the guide device in a C-arc shape over the said longitudinal extension. As a result, an arcuate movement of the guide device and thus also the consumer arranged on it, which is supplied by the line supplied in the line guide device, is possible in a particularly simple manner. If necessary, for example, for other applications, the C-arm of the guide device can also only extend over a portion of the entire longitudinal extension of the line guide device, for example by greater than or equal to 30% or greater than or equal to 50%, in particular greater than 75% or greater than or equal to 85 % the same.

The C-arc shaped guide area of the guide device preferably extends over> 90 ° or> 120 ° or up to 180 ° or more.

The C-arc-shaped guide area of the guide device preferably extends vertically over at least part of the upper run and at least part of the lower run, preferably over the entire height of the upper run and / or the entire height of the lower run. The "height" of the upper and lower run is determined by the direction in which the upper and lower run are arranged one above the other or at a height from one another Guide device are trained and both upper and lower along the line routing device can be guided laterally, i.e. transversely or perpendicularly to the longitudinal extension of the line routing device, from the C-arm.

The C-shaped guide region of the guide device is preferably designed as a rail, which is a structurally simple and at the same time mechanically stable configuration. The rail preferably extends over the height of the line guiding device, so that the upper and lower strands of the line guiding device can rest laterally against the latter. The rail can be designed in several parts or in one piece. The line guiding device guided by the guiding device can rest against the rail at the side.

In the context of the invention, the respective end region of the line routing device is generally connected to the respective connection device in such a way that it absorbs tensile force. The connection device can each comprise a strain relief for the line (s) guided in the line routing device. One of the connection devices is preferably fixed on a driver of the line guide device or movable together with such a driver or part of such a driver, the end of the line guide device connected to it being moved by moving the driver. One or the other of the connection devices preferably forms a fixed point opposite the line routing device and is preferably fixed on a bracket of the device or the machine for the guide device or connected to the water absorbing tensile force. The respective definition is made in each case preferably in such a way that the parts fixed with one another cannot be changed in position with respect to one another. The strand of the line routing device arranged on the movable connecting element or attached to it is referred to as "upper strand" in the context of the invention, so that other strands of the line management device as "lower run".

The C-shaped guide area of the guide device preferably extends over at least 50% or particularly preferably> 75% or> 90% or 100% of the longitudinal extension of the line guide device in its travel state with a maximum distance between the two end areas of the line guide device. As a result, the C-arm can be moved around the axis of curvature of the C-arm by as large an angle range as possible. This extends the application range of corresponding devices or machines, since, for example, the line routing device can be held very precisely in an arcuate position defined by the C-arm of the guiding device, without the upper and lower strands of the same undesirably coming into contact with one another when the line routing device moves come.

The line guiding device is preferably> 25% or> 50% of its total length, particularly preferably> 75% or> 90% or practically 100% of its total length against the C-arc-shaped guiding area of the guiding device. The line routing device can rest loosely with said area or else with a certain application of force against the area of disposal.

Generally within the scope of the invention, the line routing device can be guided loosely around the deflecting device, resting on the latter. The line guiding device can also be guided around the deflecting device in the longitudinal direction with a force application of the deflecting device to the deflection area of the line guiding device, whereby a further improved guidance of the line guiding device is given and a sagging of sections thereof is further reduced, since the line guiding device, so to speak, from the Deflection device is tensioned in the longitudinal direction. If necessary, the deflection device can with a constant force on the deflection area of the line guiding device.

Generally within the scope of the invention, the deflection device is at least during some or predetermined Verfahrstellun gene of the line guide device, for example. Over> 50% or> 75% of the travel path of the line guide device, or particularly preferably permanently during the entire movement of the line guide device in the longitudinal direction of the extension of the line routing device resting against the deflection region of the line routing device, for example loosely or optionally with a force applied. The deflection device is thus preferably permanently positioned during the movement of the line guide device by means of the said device for changing the position of the deflection roller in the deflection area of the line guide device so that the line guide device is guided around the device in contact with the deflection device. As a result, the deflection area of the same is stabilized when the line guiding device is moved. In particular, this also allows the line guide device to be tensioned in its longitudinal direction during some or predetermined Verfahrstel lungs of the line guide device or particularly preferably permanently during the entire movement of the line guide device and is preferably at the same time laterally force-applied against the C-arm of the guide device, whereby the Location of the line routing device is particularly precisely defined and, for example, sections of the same are effectively prevented from sagging. A certain amount of tension is already present when the tension reduces or eliminates any length play in the line routing device, such length play, for example, due to play in the joint connections of adjacent sections of the line routing device, such as in the case of a link chain or an elastic stretching device. tion of joint areas of the device can be given. The application of force is preferably such that the line routing device is free of play in its longitudinal direction as a result of it.

A deflecting device is preferably provided at each deflection region of a line guiding device, even if several line guiding devices are provided.

According to a preferred embodiment, the Umlenkein direction is generally designed in the context of the invention as a pulley, around which the line guide is deflected. The deflecting roller is preferably freely rotatable about its axis of rotation (also called "axis"). Several deflecting rollers can also be provided in an arc-shaped arrangement on a holder. However, other deflecting devices are also conceivable, for example the line guiding device can be via a deflecting part If several cable routing devices are provided on the guide device, the deflection device for each of these cable routing devices is preferably designed as a deflecting roller. The design as a deflecting roller is structurally simple, enables an exact line guiding device and, if necessary, also when force is applied to the deflecting device a low-wear embodiment on the deflection area of the line guide device in its longitudinal direction.

Preferably, a device for changing the position of the deflection device in the longitudinal direction of the line guide device is provided, which positions the deflection device when the line guide device moves in the longitudinal direction of the same on the deflection area, i.e. the deflection device in its position on the deflection area of the line guide device holds the device regardless of the position of the line guide device . The deflection device can in this case lie loosely on the deflection area or be acted upon by force in the longitudinal direction of the line guide device with respect to the deflection area. Said device is preferably designed in such a way that the deflection device rests against the deflection area of the line guide device against the deflection area of the line guide device at least during some or predetermined displacement positions of the line guide device or particularly preferably permanently during the entire movement of the line guide device in the longitudinal direction of the extension of the line guide device, possibly applying force is applied. The application of force gives the line routing device a certain bias so that the spatial arrangement of the same by the guiding device, in particular also by interaction with the deflecting device, is even better defined and undesirable sagging of sections of the line routing device is prevented to a greater extent. This avoids that when the line guiding device moves, sections of the line guiding device undesirably come to rest or sag with other sections of the guiding device, including other sections of the line guiding device, which could impair the smoothness of the line guiding device or increase wear.

The deflection device is preferably changeable in position when the line guide device is moved, specifically in the longitudinal direction of the C-shaped guide area of the guide device, whereby the deflection area of the line guide device and its spatial arrangement can be stabilized as a whole. When the guide device is moved, the deflection device is preferably moved in the longitudinal direction of the C-arc-shaped guide region of the guide device relative to the guide device. According to a preferred embodiment, the Umlenkein direction is forcibly moved with the line guiding device, so when the line guiding device is moved due to a given coupling to the Lei processing device together with this, without further devices for changing the position of the deflecting device are required.

Alternatively, the device for positioning on the deflection area, possibly also for applying force to the deflection device in the longitudinal direction of the line guide device against the deflection area, is designed as an actuator-operated device, the actuator being able to be operated, for example, resiliently, by electric motor, hydraulically or pneumatically. The actuator is different from the line routing device. By actuating the actuator, the deflection device can be acted upon by force against the deflection area. As a result, the position of the deflection device can be adjusted in a self-adjusting manner. The actuator can be mounted on the guide device, for example the C-arm thereof, if necessary with the formation of an abutment for the positioning or application of force. The deflection device can also be designed in such a way that it is positioned on the deflection area of the same by the movement of the line guide device, for this purpose, for example, to couple it to the line guide device for changing its position, so that an additional actuator can be unnecessary.

Preferably, the areas of the guide device, in particular the C-arm of the same, which come into contact or could come into contact with the cable guide device when moving the same, are equipped with a sliding friction reducing surface in order to reduce the sliding friction resistance when the cable guide device comes into contact with the guide areas of the guide devices.

The deflection device is preferably mounted so as to be freely rotatable about its longitudinal axis by means of a bearing. The bearing can be held longitudinally displaceably on the C-shaped guide region of the guide device. This creates a structurally simple embodiment, the change in position of the deflection device ensuring that it is always in the deflection area of the same when the line guide device is moved. Furthermore, this ensures in a simple manner that when the deflection roller bearing is longitudinally displaced, the line guide device can laterally rest against the C-arm. Furthermore, this construction is particularly advantageous with regard to the structural design and a minimization of wear when moving the guide device.

The deflecting device preferably projects over the line guiding device at least over part of the height of the same, that is to say extends over at least part of the height of the upper run and / or part of the height of the lower run. The "height" of the upper and lower run is their extension in the direction of the opposite run, of the upper and lower run away from this, stabilized in its position on the deflection device and secured against unintentional spacing from the deflection device, for example against sliding down the side of the deflection device overlying side of the line guide device in the Height at least partially the upper and / or lower run, preferably by> 10% or> 20%, particularly preferably> 30% or 50% or more at the height of the upper and / or lower run. Additionally or alternatively, if necessary, the deflection device preferably projects over the upper and / or lower run in height at least partially, preferably by> 10% or> 20%, particularly preferably>, on the side of the line guiding device facing the C-shaped guide area of the guiding device 30% or 50% or more at the height of the upper and / or lower run, whereby the line guide device is spaced from the guide device in the deflection area, whereby its running properties are improved.

A support device is preferably provided for the upper and / or lower strand of the line guiding device, which supports the upper and / or lower strand outside the deflection area of the respective strand in the direction of the other strand, which results in a more uniform movement of the line guiding device in whose longitudinal direction leads. The area of the support device that supports the respective strand is thus preferably arranged between the upper and lower strand. Alternatively or additionally, the support device can be arranged on the upper side of the upper run and / or the underside of the lower run. Several support devices can be arranged distributed over the length of the line routing device. A given support device can preferably rest on both the upper run and the lower run. The running properties of the line guide device are also improved by the support device in particular when the axis of curvature or rotation of the arc-shaped guide device is not arranged perpendicular to the direction of gravity. The support device can be designed, for example, as a rotatable roller or, if necessary, also as a device that cannot be changed in position with respect to the holder of the support device, or in another suitable manner, which is attached to the upper and / or lower tertrum can be applied.

The support device can at least partially overhang the respective supporting strand on the side opposite the C-shaped guide area of the guide device and / or facing side, for which reference is made accordingly to the explanations on the deflection device. As a result, the line guide device is supported in a direction transverse to this from the support device through the protruding areas of the same when the line guide device is arranged in the given position of the guide device below the same with respect to the gravity device, for example in the 6 o'clock position the same.

The support device can in each case be arranged on the guide device, in particular the C-arm thereof.

The line guide device is preferably guided through the C-arm of the guide device, with a holder for the guide device on the device or the machine being arranged on the side of the line guide device opposite the guide device. The holder preferably has a C-arm-shaped holder section. The guide device is preferably movable in its longitudinal direction relative to the holder. The line guide device can thus be arranged at least in some displacement positions over at least part of its longitudinal extension, eg> 25% or> 50% between the C-arm of the guide device and the C-shaped mounting section. As a result, on the one hand, the line guide device is protected by the two opposing C-arms, on the other hand, the C-arm-shaped area of the holder, which extends in the longitudinal direction of the line guide device, can move in an arcuate manner Allow guide device, said arcs are each preferably designed as a circular arc.

Particularly preferably, the holding area of the guide device can be moved in the longitudinal direction of the guide device on the C-shaped holder section in the longitudinal direction of the holder section, so that the guide device can be moved relative to its holder on the one hand, and the holder area for the guide device on the device or machine on the other is movable on the C-arm of the bracket, whereby the possible total travel of the guide device in the longitudinal direction of the Lei processing device increases.

If the holder of the guide device is designed as a C-arm, in particular as a circular arc section, then the C-arm area of the holder extends over preferably> 30 ° or> 45 ° or> 60 °, possibly <90 °.

The total angle of rotation of the C-arm of the guide device, including a movement of the guide device compared to its C-arm-shaped holder, is preferably> 120 ° or> 180 ° or> 195 °, without the upper run and lower run of one or two or more on the guide front Direction of arranged line routing devices come to rest with each other. This can in particular also apply if, in a displaced position of the guide device with a maximum guide device moved with respect to the holder, a free end of the guide device is located between the 12 o'clock position and the 4 o'clock position, for example in the 3 o'clock position, and the Guide device is moved counterclockwise, so the line guide device passes through the 12 o'clock position during the movement and is thus moved overhead, ie through the 12 o'clock posi tion. Preferably, the line guiding device always rests against the guide device, in particular the C-arm thereof, with at least one loading area of one of its side boundaries over the entire travel path of the same. Preferably, the line guide device always rests against the guide device, in particular its C-arm, over the entire length of one of its side delimitations over the entire travel path thereof. It is therefore always only one and the same of the two Be tenbegrenzungen the same on the guide device on all movement positions of the line guide device. As a result, an exact position of the line guide device is always given, which also ensures better and more uniform movement properties of the same. The constant rest of the line guide device on the guide device can be ensured, for example, by suitable positioning of the deflection device on the line guide device.

The C-shaped guide region of the guide device or the guide device as a whole is particularly preferably designed as a circular arc section. When the guide device is moved in its longitudinal direction, the end regions of the guide device on the said circular arc method and the envelope of the end regions of the travel path described or performed by the guide device are thus also located on this circular arc. Thus, the travel paths of a device attached to one end region of the guide device or of two devices attached to the two opposite end regions of the guide device each lie on an arc of a circle. In this way, for example, an optimal geometry is created in order to be able to detect or process an examination or processing body arranged on the axis of curvature of the C-arm, for example a patient, from different spatial directions. This can For example, medical diagnostics can be improved when examining a patient. If necessary, in the context of the invention, the C-arm of the guide device can, however, also be designed in a non-circular arc shape, for example in the form of a section of an ellipse or some other arc shape.

Preferably, the C-shaped guide area of the guide device or particularly preferably the guide device is arranged in one plane with respect to its guide area for the line guide device over its entire travel path. When moving the Führvor direction and thus also the C-arm of the same around the axis of curvature of the guide device, the Führungsvorrich device or the C-arm is thus moved in one plane. This is particularly advantageous if an object, such as a patient, arranged in the center of the guide device or on the axis of curvature of the same, by means of devices that are to be examined with the at least one or more line guide devices, as is the case with a C- Arch X-ray or MRI machine is the case. The object or the person with the area to be examined or possibly also to be processed is then preferably arranged at the point of intersection of the C-arm with the axis of curvature of the guide device. For certain applications, the C-arm of the guide device can also have a different shape and, for example, also be designed as part of a helix or spiral, the pitch of the helix or spiral being preferably much smaller than the radius of the C-arm, for example wise less than / equal to a fifth or less than / equal to a tenth of the same.

The guide device preferably has a first and a second connection device, the first connection device having a first end region of the line guide approximately device and the second connection device is connected to the second end region of the line routing device. The first and second end regions of the line guiding device are preferably each connected to the respective connecting device in a force-transmitting manner. One of the two connection devices, for example the first connection device, is preferably fixedly connected to the guide device or generally not in a position-changeable position in the longitudinal direction of the guide device when the line guide device is moved, preferably permanently connected to it. The other connection device, for example the second connection device, is preferably variable in position with respect to the guide device, for example when the line guide device is moved in relation to this and / or in relation to the line guide device, in particular in relation to the longitudinal extension of the guide device and / or the line guide device . At or in the area of the first and / or the second connection device, a strain relief can be provided for the lines such as hoses, cables or the like routed in the inner cross-section or receiving space of the line routing device.

According to a particularly preferred embodiment, the guiding device has in addition to the first line guiding device (at least) a second line guiding device, both, ie the first and second, line guiding devices each having a first end area on the first connection device and both line guiding devices each with a second end area are richly connected to the second connecting device, the first line routing device starting from the first connecting device in the direction of a first end area of the C-arm of the guiding device, and the second line routing device extending. extending from the first connection device in the direction of the second end region of the C-arm of the guide device. The first and second line guide devices are thus arranged in opposite directions to one another on the guide device, ie arranged in a loop. When the guide device is moved in the direction of the longitudinal extension of the C-arm of the same, one of the line guide devices, for example the first, is moved in the direction of its extended end position, in which the lower run of the cable guide device in relation to the movement of the line guide device is a Has maximum length and that the opposite strand, so the upper strand, has a minimum length. This displacement state of the first line routing device is referred to here as the displacement state Imax. In the Ver travel positions of the guiding device, in which the first line guiding device is in the travel state Imax, the travel position is exactly the opposite, i.e. the lower run of the second line guiding device is in the travel position Imax with a minimum length and the upper run is in one maximum length. The first and the second line routing device thus essentially form a closed loop, the two line routing devices each extending to a different end or end region of the guiding device. The first and the second line routing device are preferably guided by the same guide device, depending on the displacement position of the two line routing devices, a predetermined area of the guide device can thus guide part of the first or the second line routing device, in particular with regard to the upper run of the same. The provision of a common guiding device for the first and second line guiding devices has the advantage of a particularly simple construction that also takes up only a small amount of space. If necessary - less preferred - however, separate guide areas or separate guide devices can also be provided for the first and second line guide devices, which, for example, have a height offset in relation to the radial arrangement of the guide device to the axis of curvature, i.e. are arranged at different radial distances from the axis of curvature. If necessary, the first and second guiding devices for the first and second line guiding devices can also have a lateral offset to one another, for example at different sections of the axis of curvature of the guiding device (in particular: the guiding device for the first line guiding device), that is to say in relation to each other be arranged in the longitudinal direction of the axis of curvature behind one another. If necessary, more than two line guide devices can be provided on the guide device.

By arranging a first and a second line guide device on the guide device, a larger number of lines such as cables or hoses can be guided from the first connection device to the second connection device. This is advantageous, for example, when the receiving space of the first line routing device for lines is already occupied and it is necessary to route additional lines from the first to the second connecting device to the technical device such as a consumer at the end of the guiding device to be adequately supplied with media carried in the lines.

Regarding the embodiment with two or more line routing devices, with regard to the features of the line routing devices and / or the guiding device and / or the device or the machine, reference is made in general to the other remarks on the invention. possibly taking into account the respective different extension directions of the respective line routing device. This also applies accordingly with regard to the statements on the arrangement with only one line routing device, unless this contradicts this or the context does not result otherwise in detail, taking into account the respective different direction of extension of the respective line routing device. This also applies in each case with regard to other devices described in the context of the invention, such as a support device or other devices.

For arrangements with only one line routing device, the statements on the arrangement of two or more line routing devices apply accordingly, provided they do not contradict this.

Particularly preferably, the two deflecting devices in the line guiding devices are positioned by a common device on the two deflecting areas of the line guiding devices and / or are subjected to force in the longitudinal direction of the two line guiding devices against the deflecting areas of the same. Preferably, the order deflection devices are designed as deflection rollers.

The common positioning device of the deflection devices ensures that the two deflection areas of the two line routing devices are always arranged in their desired position relative to the two line routing devices, preferably over the entire travel of the line routing devices. In this way, in particular, undesired changes in the position of sections of the line routing devices, for example a hanging through of such sections, which could impair the smoothness of the movement of the line routing devices, are avoided. On constructively special In a simple manner, the axes of the deflection devices of the line guide devices, for example of Umlenkrol len thereof, can be held at a predetermined distance from one another by a spacer. The spacer can be rigid. As a result, the total length of the arrangement of the two line guide devices is defined by the positions of the deflection devices, each of the line guide devices being guided in its deflection area around one of the deflection devices, adjacent to it. If the two line routing devices are arranged in a loop, a spacer for the deflection devices can also be arranged in the loop, the spacer being able to be mounted in a floating manner and carried along by the movement of the line routing devices. The spacer can be rigid. With regard to the positioning of the deflection devices at the deflection areas of the line guiding devices, reference is also made to what has been said above, for example an actuator can also be provided for positioning the deflection devices, here also an actuator which is connected to both deflection devices that are jointly in applying force in different directions, coupled. The actuator can, for example, be arranged between the two deflection devices or deflection rollers and exert a spreading force on them and / or the bearings or brackets thereof, in the direction of a spacing of the two deflection rollers from one another, so that these two deflection rollers on a constant Maintain a distance from one another and thereby position at the deflection areas of the two line guide devices and / or also apply force to the deflection devices in the longitudinal direction of the line guide devices against the deflection areas.

If necessary, a separate deflection device can also be provided for each of the deflection areas of the line routing device (s). If necessary, it can also be used for each of the a separate actuator can be provided for both (or generally several) deflection devices in order to position the respective deflection device on the deflection area of the respective line guiding device.

The movement of the deflection device for the respective deflection area with the arrangement of at least one or at least two line guide device (s) and positioning of the deflection device on the respective deflection area of the line guide device which is deflected around the deflection device can be done in different ways. This applies in particular to the arrangement of two line routing devices with a loop-shaped arrangement, the two deflection areas of the two line routing devices being aligned with opposite end areas of the guiding device and preferably being arranged at a constant distance in the longitudinal direction of the line routing device. Preferred embodiments are described below.

According to a first preferred embodiment UI, the at least one or the at least two deflection devices is positively guided by the line routing device deflected at this, that is, by the movement of the end area or areas of the at least one or preferably two end areas of two loop-shaped line guiding devices, the deflection device is forced changed in their position. In the case of two looped line routing devices, the two deflecting devices arranged at the deflection areas can be held in their desired position by a spacer arranged in the loop, ie between the opposite deflection areas. The spacer can be at least essentially rigid; it can optionally also be elastically compressible in its longitudinal direction with the exertion of force and load on the two from the inside opposite deflection areas. The spacer can be freely changed in position relative to the guide device in its longitudinal direction. The two end regions of the two line routing devices are preferably arranged in front of a connection device or fixed to it in a force-transmitting manner. The connection device can be fixed to the guide device in a force-absorbing manner and thus act as a driver or couple it to a driver of the guide device in a force-transmitting manner, so that by changing the position of the driver, the end region (s) of the line guide device (s) and thus also the deflection regions thereof are moved.

According to a further preferred embodiment U-II, the at least one or the at least two Umlenkein directions of the line guiding device (s) are driven by a motor by means of a corresponding drive in order to position the deflecting device (s) on the deflecting area (s) when the line guiding device is moved. The motor drive preferably acts directly on the deflection device of the respective deflection area while changing the position of the same. The motor drive is preferably electronically controlled. The control of the motorized drive can take place as a function of a detected change in position of the guide device, so that the deflection area (s) are moved by means of the drive synchronously to a change in position of the guide device in the longitudinal direction of the line guide device. It goes without saying that there is thus a detection device for determining the position or change in position of the guide device and a corresponding transmission of measured values to the control of the drive. The measured value acquisition of the position of the guide device can be done by detecting the actuation of the drive such as an electric motor of the guide device. The end area (s) of the cable routing device (s) can thus be floating or floating. not be connected to the guide device in a force-transmitting manner. For example, the drive can be mounted on the guide device in a variable position in the longitudinal direction of the guide device and can change its position in the longitudinal direction of the guide device as a result of the driving force. The drive can optionally also be mounted on another device of the device or the machine and have a position-changeable or length-changeable actuating element, which couples to the deflection device in order to position it as intended, for example under a change in position relative to the guide device.

According to a further preferred embodiment U-III, the target position of the at least one or the at least two deflecting devices of the line routing device (s) can be adjusted in a controlled manner. For this purpose, for example, a sensory force absorption at a driver and / or fixed point of the cable routing device (s) and / or a section of the cable routing device (s) and the deflection device at the respective deflection area of the cable routing device is moved into its desired position by means of a suitable drive with readjustment. in which the force absorption is made powerless, so a Krafteinwir effect of zero and is thus readjusted.

According to a further preferred embodiment U-IV, the at least one or the at least two deflection devices are spring-preloaded by means of a spring device and positioned in their desired position on the respective deflection area of the line guide device. The spring device can be coupled to the deflection device for spring preloading and can preload it with respect to the respective deflection area or, by means of the spring force, preferably apply force in the longitudinal direction of the line. If a cable routing device is provided, the abutment of the spring pretensioning device can, for example, be on the guide Device or the C-arm of the same arranged, preferably as this / this is arranged in a stationary manner. If two line guiding devices are provided which are arranged in a loop, that is to say running to opposite ends of the C-arm of the guiding device, a spring tensioning device can be provided which engages the two opposite deflecting areas or the deflecting devices thereof and holds them in their desired position with spring force or acted upon by force in the direction of spacing from one another. Separate spring preloading devices can also be provided for each of the deflection areas, each of which has, for example, an abutment on the guide device or the C-arm of the same.

The invention further comprises a device or a machine, in particular a C-arm X-ray or C-arm MRT device, with a guide device according to the present invention, including a line guide device. In general, the respective device or the machine can be a medical device such as diagnostic devices, or else a device or a machine for material processing or the like, without being restricted to this in each case.

The device or the machine preferably has a holding device for the guide device, the guide device being movable in its longitudinal direction relative to the holder. In general, within the scope of the invention, the at least one, two or possibly also several line routing device / s guided by the guide device on the side opposite the C-arm of the guide device is also surrounded by a C-shaped component, so that the one, two or if necessary, several line guide devices are surrounded on two opposite sides by C-arm-shaped components. The C-shaped component opposite the C-arm of the guiding device in relation to the line guiding device (s), in particular re in execution as a C-arm, preferably represents the holder for the guide device on the device or the machine or a part of the holder or connected to it or represents a part of a housing enclosing the line guide device (s), the housing generally can be designed completely closed or partially open. By moving the guide device with respect to the C-shaped component such as, for example, holding part, a telescopic movement can thus be carried out, more precisely a telescopic movement with an arcuate course. The C-arm of the guide device and the arc-shaped mounting area or C-arm of the mount, in the sense of a mount for the guide device, can be designed as concentric arcs, in particular concentric circular arcs.

The C-shaped component opposite the guiding device extends preferably over> 15% or> 25%, or possibly also> 50% over the longitudinal extent of the line guiding device / s, including the maximum length of the line guiding device / s in their entirety dig extended state is understood.

Generally within the scope of the invention, the guide device, in particular the C-arm thereof, can be arranged on a slide, the guide device being slidable in its longitudinal direction relative to the slide. The guide device can be attached to the Schlit th here. The slide, in turn, can be arranged on the holder of the device or the machine for the guide device, wherein the slide can be displaceable relative to the holder in the longitudinal direction of the holder and / or the longitudinal direction of the guide device. Due to the arrangement of the carriage, a distance is created between the C-arm of the guide device and the holder, in which preferably the line guide device (s) is / are arranged. Furthermore, by means of this arrangement, a consumer or technical device arranged on the guiding device, which is supplied with media by the line or lines arranged in the line guiding device (s), can be moved over a larger arc area, possibly over the entire length of both C-arcs, which extends the area of application of the device or machine.

Generally within the scope of the invention, the axis of the C-arm of the guide device is preferably arranged transversely or perpendicular to the direction of gravity, that is to say to the Z-axis of the installation space of the device or machine comprising the guide device. The axis (i.e. axis of curvature) of the C-arm can preferably have an angle of 30 to 150 °, preferably 45 ° to 135 °, particularly preferably 60 ° to 120 ° or approx. 90 ° to the direction of gravity. In this arrangement, the advantages of the Führungsvorrich device according to the invention come into play in a special way.

The two or more end regions of the line guide devices can be attached to a common construction part, but optionally also to several components, which are preferably not changeable relative to one another. The connection elements of the connection device, which in each case directly hold or fix an end region of the respective line routing device, can be arranged at a distance from one another, this distance increasing when the guide device is moved. device and thus also the line routing devices before preferably does not change. The two connection elements can be arranged on one and the same component of the holder or generally of the device or machine such as, for example, a flange or collar, or also on different components of the device or the machine. The same can apply independently of this or in combination with this for the two connection elements of the other (second) connection device which, for example, can be arranged on a driver of the line guide devices for moving the same.

The invention is described below by way of example and explained with reference to exemplary embodiments and described in the figures. All features of the exemplary embodiments are disclosed independently of one another within the general scope of the invention. The same components are provided with the same reference numerals in the various figures. Show it:

The device or machine 1 according to the invention, here for example as a C-arm X-ray device or C-arm MRI device, comprises a guide device 5 for a line routing device with at least one such line routing device 10 (see FIGS. 1-5). The line guide device 10 has a longitudinally extending, continuous free inner cross section 11 for receiving at least one line 12 such as hose, cable or the like. The line routing device 10 has a multiplicity of sections 13 arranged one behind the other in the longitudinal direction thereof and spatially deflectable to one another. The line routing device 10 is arranged in an arrangement with a lower strand 14, an upper strand 15 and a deflecting area 16 connecting them, the deflecting area 16 having a deflecting axis 16a around which the line guiding device 10 is deflected. The line routing device 10 has two side boundaries 17a, 17b, the lateral spacing of which determines the width of the line routing device 10 and wherein the side boundaries are arranged at least substantially perpendicular to the facing upper and lower sides 15a, 14a of the upper and lower strands 15, 14 are. The guide device 5 is at least with a longitudinal section of the same or over its entire length, with which it guides the line guide device 10 in its longitudinal direction, with a C-arc-shaped guide area 6 with a curvature tion axis 6a of the C-arm and is formed with a convex inner curvature 6c and a concave outer curvature 6d.

At one end of the guide device 5, a holder 76 is provided to fix a technical device 75 such as a consumer, which is supplied with the lines guided by the line guide device (s) 10, 100, the lines from the device or machine are fed from the connection point la.

According to the subject matter of the invention and FIGS. 1-5, the guide device 5 has a deflection device 20 with a deflection axis 20a, the deflection region 16 of the line guide device 10 being guided around the deflection device 20. The axis 20a of the deflection device 20 forms an angle with the axis of curvature 6a of the C-arc-shaped guide region 6 of the guide device 5, here an angle of 90 °. The angle of the deflection axis 20a of the deflection device 20 for the line guide device 10 to the axis of curvature 6a of the C-arc-shaped guide region of the guide device is 90 ° here. The axis of curvature 6a corresponds to the axis of rotation about which the guide device can be rotated.

One of the side boundaries 17a of the line guide device 10 is arranged facing the concave curved outer side 6d of the C-arc-shaped guide region 6 of the guide device 5. The side boundary 17a (and preferably only this one side boundary) of the line guide device 10 lies when the line guide device is moved over at least part of its longitudinal extent on the concave curved outside of the C-arc-shaped guide area of the guide device, here over the entire travel path or The entire movement of the line guide device between its two end points of the Travel path, i.e. maximum travel in one and the other direction of travel. The line routing device can in this case over> 50% or> 75% or or> 90%, preferably at least approximately, for example up to the area of the line routing device on the deflection device, practically over its entire length on the side of the C-arm of the guide device issue. The Füh approximately device is only on the side boundary of the line guide device, so not for example se on the top of the upper run or the underside of the lower run, which reduces friction and structural effort, but this may also be the case.

Due to the construction described, the Führungsvorrich device 5 with line guiding device 10 has only a small overall height, so small radial extent to the axis of curvature of the C-arm of the guide or to the axis of rotation of the Füh approximately device. As a result, the guide can be moved further in the direction of the installation surface A of the device or the machine or the installation surface does not hinder the movement of the guide device with line guiding device to the installation surface and beyond, i.e. beyond the 6 o'clock position U6 in the direction of 3 o'clock position U3. Furthermore, this avoids that when the line routing device is arranged "overhead", i.e. in the 12 o'clock position U12, the upper run sags and can come into contact with the lower run, as can conventionally be the case, since the line guiding device " is placed on its side ", so it is supported on the side of the guide device.

The C-arc-shaped guide area 6 of the guide device 5 extends here over> 50%, more precisely 100%, of the longitudinal extent of the line guide device 10 in its moving state with the maximum distance between the two end areas 10a, 10b of the line routing device 10 to one another in both directions of travel of the line routing device.

A device 25 is provided here for changing the position of the order guide device 20 in the longitudinal direction of the line guide device 10, which positions the guide device 20 in its position on the deflection area 16 of the line guide device 10 regardless of the displacement position of the line guide device 10. This is realized here in that the deflection device 20 is arranged and fastened to the guide device and the guide device thus positions the deflection device 20 on the deflection region 16. To set the positioning, the deflection device can be displaced in the longitudinal direction with respect to the guide device, for example manually, and can be fixed in its desired position with respect to the guide device, to be more precise, on the latter. The positioning of the deflection device 20 can also take place in other ways, for example, the deflection device can be positioned by an actuator on the deflection area according to an alternative embodiment, the actuator in for example depending on the displacement position of the guide device and / or the line routing device is operated.

The deflection device 20 is rotatably mounted ver by means of a bearing 21. The bearing 21 is held here in a longitudinally displaceable manner on the C-shaped guide area of the guide device. The deflection device 20 is designed here as a rotatable deflection roller.

The deflection device 20 overhangs the line guide device 10 over part of the height of the same in relation to the upper run and the lower run, according to the Ausfüh approximately 25% of the height of the same, for which the deflection device designed as a pulley has a rin- Nen-shaped radial outer surface, around which the line routing device is deflected, so that the line routing device is thus arranged in the channel.

Furthermore, a support device 28 is provided for the upper and / or lower strand of the line guiding device, which supports the upper and / or lower strand outside the deflection area in the direction of the respective other strand. The support device in this case rests on both the upper and lower run, possibly also only on the upper or lower run, it being possible for a separate support device to be provided for the other run in each case. The support device is designed here as a rotatable support roller. The support device projects over the respective strand on which it rests, in height, for example by approximately 20%, on the side opposite the C-arm of the guide device or here on both sides. As a result, the target position of the line guide device is additionally stabilized, when the axis of rotation of the C-arm of the guide device is arranged perpendicular to the direction of gravity, but in particular also when it is inclined to this, i.e. at a non-perpendicular angle. The support roller can be designed like the deflection roller.

The line guide device 10 always rests against the guide device 5 with at least one area of one of its side delimitations 17a over its entire travel path, here practically over the entire longitudinal extent of the side delimitation.

The C-arc shaped guide area 6 of the guide device 5 is designed as a circular arc. The C-shaped guide area 6 of the guide device is arranged in one plane. The guide device 5 has a first connection device 30 and a second connection device 35, the first connection device 30 being connected to a first end of the line routing device 10 and the second connection device 35 being connected to the second end of the line routing device 10. The first connection device 30 is in this case relative to the guide device 5 and thus also relative to the C-shaped guide area 6 of the same variable and, for example, on the holder of the device or the machine for the guide device is arranged or fixed on this, with the Führungsvorrich device relative to the holder is movable. The first connection device 30 forms a fixed point in relation to the movement of the line routing device. The second connection device 35 is fixed to the guide device 5 and the C-arm of the same is fixed, more precisely on the guide device 5. The second connection device 35 thus represents a driver for the line routing device 10 when it is moved.

It goes without saying that the routed line (s) are routed in a suitable manner from the first connection device 30 to the connection point 1 a of the device or the machine, which is not shown in the figures.

The guiding device 5 here has a second line guiding device 100 in addition to the first line guiding device 10, both line guiding devices 10, 100 each having a first end on the first connection device 30 and both line guiding devices 10, 100 each having a second end thereof are connected to the second connection device 35. The first line routing device 10 extends starting from the first connection device 30 in the direction of a first end of the C-arm-shaped guide region 6 of the Guide device 5. The second line guide device 100 extends from the first connection device 30 in the direction of the second end of the C-shaped guide region 6 of the guide device 5. Said first and second ends represent the ends of the opposite ends of the guide device in the longitudinal direction The two line routing devices 10, 100 are thus arranged in a loop.

The statements on the first line routing device 10 also apply here correspondingly to the second line routing device 100, including the statements on the deflection device, taking into account the different directions of extension of the two line routing devices 10, 100.

One or both of the connection devices 30, 35 have separate connection elements for the two line routing devices 10, 100, it being possible for the two connection elements to be arranged adjacent to one another on the respective connection device. A strain relief is provided on each of the connection elements or in the area thereof for lines which are routed from the line routing device connected to the respective connection element.

The two deflection devices 20, 120 of the two line guide devices 10, 100 are through a common

Device positioned on the two deflection areas 16, 116 of the line guide devices 10, 100. The common device is the guide device, more precisely the C-arm of the same. The two deflection devices 20,

120 are subjected to force in the longitudinal direction of the two line guide devices 10, 100 against the respective deflection area of the same, including in the simplest case the order of the deflection device when it is installed, force-applying to the Deflection areas positioned and this position can then be set for example on the guide device.

4 shows a schematic representation of various embodiments U-I to U-IV for positioning the deflection device (s) in their desired position on the respective deflection area of the line routing device (s) (FIGS. 4A-4D). The exemplary embodiments are each shown with a guide device 5 with two looped line routing devices 10; it goes without saying that corresponding embodiments can also be implemented in guiding devices with only one line routing device.

According to a first embodiment UI (FIG. 4A), the two deflecting devices 420 are positively guided by the cable routing device 410 that is deflected on this and are forcibly changed in their position by the movement of the end regions of the two ends of the two looped cable routing devices that are brought together at a movable connection device . The two order steering devices are arranged in the loop of the two line guide devices. The two Umlenkeinrich lines are held by a rigid spacer 415 in their desired position relative to each other and thus when the line routing devices are moved in their respective target position on the deflection areas. When the line routing devices are moved in one direction, the spacer thus moves with the line routing devices.

According to an embodiment U-II (Fig. 4B), the two deflecting devices 420 of the line routing device / 410 are motor-driven by means of a corresponding drive 430 in order to move the deflecting device (s) at the deflection area or areas when the line guiding device is moved. position. The motor drive 430 acts directly on the deflection device 420 with the deflection axis 420a of the respective deflection area, changing the position of the same. The motor drive is controlled electronically by means of the Steue tion 432, depending on a detected change in position of the guide device, here with the detection of the operating parameters of the drive of the guide device. Each of the deflection devices 420 is assigned a separate drive 430 for changing its position; if necessary, a common drive can also be provided by a suitable coupling mechanism. The drive is variable in position here on the guide device 5 supported tert.

According to the embodiment U-III (FIG. 4C), the target position of the deflection devices 420 is readjusted at the deflection areas 416 of the line routing devices 410. For this purpose, a sensory force transducer 437 is provided on a follower 438 and / or fixed point of at least one or both of the line routing devices and / or a section of at least one or both of the line routing devices. The deflection device 420 at the respective deflection area 416 of the line routing device 410 is moved into its desired position by means of a suitable drive 440 with readjustment. A common drive or separate drives can be provided for the two deflection devices, each of which is controlled in a readjusting manner. In this case, a connection device for the end region or regions of the one or both line guide devices can be provided which does not couple to the guide device, which can generally be the case within the scope of the invention.

According to the embodiment U-IV (FIG. 4D), the at least one or the at least two deflection devices 420 with deflection axis 420a are fixed by means of a spring device 450. which are preloaded and positioned in their desired position on the respective deflection area 416 of the line guide device 410. The spring device can be coupled to the deflecting device for spring preloading and preloading it with respect to the respective deflecting region or applying force by means of the spring force, preferably in the longitudinal direction of the line routing. Depending on the arrangement of the abutment of the Federein direction and the direction of travel of the line routing device, the spring element can be designed as a tension or compression spring. If two loop-shaped line routing devices 410 are provided, a spring tensioning device can act on both opposing deflection areas 416 and hold them in their desired position, for example, apply spring force away from one another in the direction of the spacing of the deflection areas.

The device or machine 1 (FIG. 5) has a holder 50 for the guide device, the guide device 5 being movable in the longitudinal direction of the same relative to the holder 50. On the side of the line routing device 10 opposite the guide device is a C-arc-shaped section 51 which, according to the exemplary embodiment, is also fixed to the holder 50 and which is designed here as a circular arc section. The two C-arms 6, 51 are arranged concentrically to one another, around the axis of curvature 6a.

The guide device 5 is supported here on a slide 60 and can be moved relative to this in the longitudinal direction of the device 5.
