Device for guiding a cable
The invention relates to a device for guiding at least one cable between a first system component connected to the cable and a second system component which is relatively rotatable and/or displaceable with respect to the first and is connected to the cable, whereby the cable exhibits a cable modality which can be changed by displacement and/or rotation of the second system component, whereby at least one device for adapting the cable modality is present. By making available a guide medium which allows the device for adapting the cable modality to be guided according to the displacement and/or rotation of the second system component, it is possible to provide a device which supports a mobile device without the function of the device being restricted by the cable guide.
1. A device for guiding a cable of a system in a medical procedure, comprising:
a first system component connected to a first cable;
a second system component connected to a second cable which is relatively movable with respect to the first system component;
a cable adapting device sequentially connected to the first and second cables which adapts a cable modality of the first and second cables;
a guide medium which guides the cable adapting device according to a movement of the second system component;
wherein the cable adapting device includes at least one device which adapts a cable modality of each of the first and second cables by adjusting the length of each of the first and second cables; and
wherein the length of each of the first and second sequentially connected cables is independently adjusted by reeling up and unreeling the cables onto or off of a reel and unreel device provided as the at least one device within the cable adapting device.
2. The device as claimed in claim 1 , wherein the cable modality is a length and a torsion of each cable at a relative position of the first system component with respect to the second system component and changes with the movement of the second system component.
3. The device as claimed in claim 1 , wherein the guide medium is fitted to a boundary of a space for performing the medical procedure.
4. The device as claimed in claim 3 , wherein the boundary of the space is a ceiling or a side wall of a room where the medical procedure is performed.
5. The device as claimed in claim 1 , wherein the guide medium comprises a guide rail.
6. The device as claimed in claim 1 ,
wherein the guide medium comprises two first guide rails and a second guide rail, and
wherein the two first guide rails are parallel with respect to each other and are orthogonal with respect to the second guide rail.
7. The device as claimed in claim 6 , wherein the second guide rail is mounted on the first guide rail and is movable on the first guide rails.
8. The device as claimed in claim 1 , wherein the first or second cable is removable from at least one of the system components.
9. The device as claimed in claim 1 , wherein the cable adapting device is pivot-mounted on the second guide rail.
10. The device as claimed in claim 1 , wherein the cable adapting device is adapted to a property of the cable.
11. The device as claimed in claim 1 , wherein the device comprises a plurality of cable adapting devices.
12. The device as claimed in claim 1 , wherein the first system component is a controller or a power supply of the system.
13. The device as claimed in claim 1 , wherein the second system component is a robot system.
14. The device as claimed in claim 13 , wherein the robot system is a medical examination device.
15. The device as claimed in claim 14 , wherein the medical examination device is an X-ray unit comprising a removable C-arm.
16. The device as claimed in claim 1 , further comprising a drive device which moves the cable adapting device along the guide medium or rotates the cable adapting device around the guide medium.
17. The device as claimed in claim 16 , wherein the drive device is controlled by a controller.
18. The device as claimed in claim 1 , further including rotatable bearings formed as part of the reel and unreel device, wherein the rotatable bearings allow the rotation of the cables thereby adapting a cable modality of each of the first and second cables by reducing the shear forces of the cables as they are being reeled or unreeled onto or off of the reel and unreel device.
19. The device as claimed in claim 7 , wherein the device for adapting the cable modality pivots around an axis of rotation aligned perpendicular to the ceiling.
20. A method for guiding a cable of a system in a medical procedure, comprising:
connecting a first system component to a first cable;
connecting a second system component to a second cable;
relatively moving the second system component with respect to the first system component;
adapting a cable modality of the cable in a cable adapting device sequentially connected to both the first and second cables;
guiding the cable adapting device by a guide medium according to the movement of the second system component;
wherein the cable adapting device includes at least one device to adapt the cable modality of each of the first and second cables by adjusting the length of each of the first and second cables; and
wherein the length of each of the first and second sequentially connected cables is independently adjusted by reeling up and unreeling the cable onto or off of a reel and unreel device provided as the at least one device within the cable adapting device.
21. The method as claimed in claim 20 , further including adapting a cable modality of each of the first and second cables by reducing the shear forces of the cables as the cables are being reeled or unreeled onto or off of the reel and unreel device by providing rotatable bearings formed as part of the reel and unreel device wherein the rotatable bearings allow the rotation of the cables.
