DETAILED DESCRIPTION OF THE DRAWINGS

(7) FIG. 1 shows a medical apparatus 1 in the form of an operating table. The medical apparatus 1 comprises a tabletop 2 and a height-adjustable column 3 supporting the tabletop 2. The tabletop 2 and a base of the column 3 are movable with respect to each other. Furthermore, the medical device 1 comprises a cable routing system 4 according to the present disclosure.

(8) FIG. 2 shows the cable routing system 4 and cables 5 attached to the cable routing system 4. The cable routing system 4 comprises a flexible flat band 6 being able to be deformed from its stretched out shape without assuming a permanent changed form and several attaching devices 7 in intervals along a longitudinal direction of the band 6 for attaching the cables 5 to the band in a sliding manner. In the embodiment shown in FIG. 2, five cables 5 are attached to the cable routing system 4, however, in alternative embodiments, at least one cable 5 up to a respectively maximum possible quantity is attached to the cable routing system 4.

(9) The band 6 is made of spring steel. Alternatively, the band 6 is made of carbon fiber or of another suitable material providing a high flexibility and a sufficient strength and stiffness. The band 6 is electrically conductive and it is provided with several electrical connection devices 8 arranged in areas of ends of the band 6 in the longitudinal direction. Alternatively, the band 6 is merely provided with one electrical connection device 8 for providing EMC protection or more than two electrical connection devices 8 are provided such that components of the medical apparatus 1 midway between the ends can be conductively joined to the cable routing system 4.

(10) FIG. 3 shows an enlarged portion of the cable routing system 4 of FIG. 2. The attaching devices 7 are respectively provided with two protrusions 9 protruding from at least one of an upper side and a lower side of the band 6. Furthermore, the attaching devices 7 are respectively provided with a holding element 10 attached to the two protrusions 9. The holding element 10 extends across the width of the band 6 along a side of the band 6. In alternative embodiments, the attaching devices 7 are not respectively provided with two protrusions 9 but at least one protrusion 9 is provided or more than two protrusions 9 are provided. Furthermore, in alternative embodiments, the holding element 10 does not extend across the width of the band 6 but it extends at least partially across the width of the band 6.

(11) The holding element 10 comprises a pin 11 attached to the two protrusions 9. The pin 11 is attached to the protrusions 9 in a rotatable manner around its axis. Alternatively, the pin 11 is not rotatably attached to the protrusions 9 but, for reducing static friction between the cable 5 and the pin 11, the pin 11 is, e.g., provided with a slide coating or with a rotatable bushing. In a further alternative embodiment, instead of the pin 11, the holding element 10 comprises a molded part to be clipped on the two protrusions 9. The molded part has a surface for reducing friction.

(12) FIG. 4 shows a schematic view of a portion of the medical apparatus 1 including the cable routing system 4.

(13) The medical apparatus 1 comprises two holding devices 12′, 12″. One of the holding devices 12′ is attached to the column 3 (FIG. 1) and the other holding device 12″ is attached to a mechanical structure of the tabletop 2 (FIG. 1). Alternatively, the holding devices 12′, 12″ can be attached to other components of the medical apparatus 1 movable with respect to one another. The holding devices 12′, 12″ and the cable routing system 4, in areas of ends of the band 6 in its longitudinal direction, respectively comprise a junction device 13′, 13″ such that the band 6 is movable with respect to the holding devices 12′, 12″ at the junction devices 13′, 13″. Alternatively, only one junction device 13′, 13″ enables that the band 6 is movable with respect to one of the holding devices 12′, 12″ at the junction devices 13′, 13″ or the band 6 is not movable with respect to the holding devices 12′, 12″ at the junction devices 13′, 13″. The movability of the band 6 with respect to the holding devices 12′, 12″ is a rotation around an axis perpendicular to the longitudinal direction of the band 6 at the junction device 13′, 13″, however, in alternative embodiments, the motion can be a rotation around another axis.

(14) Moreover, the medical apparatus 1 comprises a deflection device 14 deflecting the cable routing system 4 when the holding devices 12′, 12″ are moved with respect to one another. Along its course in the longitudinal direction, the band 6 is bent around axes in a direction perpendicular to the longitudinal direction of the band 6.

(15) Furthermore, as to be seen in FIG. 3, the cable routing system 4 is guided into a free installation space 15. Starting at an opening 16 where the cable routing system 4 enters into the installation space 15, the installation space 15 extends in a direction which is not a direction of the motion of the movable components with respect to one another, i.e., the tabletop 2 with respect to the column 3, as shown by an arrow 17.

(16) In use, when translating the components of the medical apparatus 1 with respect to one another, e.g., when, in FIG. 3, the right-hand holding device 12″ is translated upwardly with respect to the left-hand holding device 12′, the band 6 of the cable routing system 4 is moved out of the free installation space 15. Thereby, the band 6 is deflected by the deflection device 14. On the other hand, when the right-hand holding device 12″ is translated downwardly with respect to the left-hand holding device 12′, the band 6 enters into the free installation space 15 by being deflected by the deflection device 14. By the rotatory conjunction to the holding devices 12′, 12″, the band 6 can flexibly enter into the available free installation space 15 in case of the translation of the components.

(17) While the invention has been illustrated and described in detail in the drawings and the foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. The invention is not limited to the disclosed embodiment. From reading the present disclosure, other modifications will be apparent to a person skilled in the art. Such modifications may involve other features, which are already known in the art and may be used instead of or in addition to features already described herein. In the claims, the word “comprising” does not exclude other elements or steps, and the indefinite article “a” or “an” does not exclude a plurality.
