Abstract

A C-arm x-ray device includes a C-arm and bearing rollers, on which the C-arm is moveably mounted. At least one drive unit drives or brakes the C-arm with the bearing rollers. The at least one drive unit is actively connected to the bearing rollers.

Claims

1. A C-arm x-ray device comprising:

a C-arm;

bearing rollers, on which the C-arm is moveably mounted; and

at least one drive unit operable to move and brake the C-arm with the bearing rollers,

wherein the at least one drive unit is actively connected to the bearing rollers.

2. The C-arm x-ray device as claimed in claim 1, wherein the C-arm is rotatably moveably mounted about an orbital axis on the bearing rollers,

wherein the at least one drive unit comprises an orbital drive unit operable to rotate and brake the C-arm with the bearing rollers, and

wherein the orbital drive unit is actively connected to the bearing rollers.

3. The C-arm x-ray device as claimed in claim 2, wherein the orbital drive unit includes an electrical orbital motor.

4. The C-arm x-ray device as claimed in claim 3, further comprising at least one belt pulley that drives the electrical orbital motor.

5. The C-arm x-ray device as claimed in claim 4, further comprising at least one belt, the at least one belt pulley operable to move the at least one belt.

6. The C-arm x-ray device as claimed in claim 5, wherein the at least one belt is actively connected to at least one of the bearing rollers such that the at least one belt transmits power onto the at least one bearing roller.

7. The C-arm x-ray device as claimed in claim 2, further comprising a guide rail or a wire race on a surface of the C-arm facing one of the bearing rollers,

wherein the bearing rollers are actively connected to the guide rail or the wire race.

8. The C-arm x-ray device as claimed in claim 1, wherein the C-arm is moveably mounted in the horizontal direction on the bearing rollers,

wherein the at least one drive unit comprises a horizontal drive unit operable to move and brake the C-arm with the bearing rollers, and

wherein the horizontal drive unit is actively connected to the bearing rollers.

9. The C-arm x-ray device as claimed in claim 8, wherein the horizontal drive unit includes an electrical horizontal motor.

10. The C-arm x-ray device as claimed in claim 9, further comprising at least one belt pulley that the horizontal motor drives.

11. The C-arm x-ray device as claimed in claim 10, further comprising at least one belt, the at least one belt pulley operable to move the at least one belt.

12. The C-arm x-ray device as claimed in claim 11, wherein the at least one belt is actively connected to at least one of the bearing rollers such that the at least one belt transmits forces onto the at least one bearing roller.

13. The C-arm x-ray device as claimed in claim 8, further comprising a guide rail or a wire race,

wherein the bearing rollers are actively connected to the guide rail or the wire race.

14. The C-arm x-ray device as claimed in claim 12, further comprising a guide rail or a wire race,

wherein the bearing rollers are actively connected to the guide rail or the wire race.

15. The C-arm x-ray device as claimed in claim 3, further comprising a guide rail or a wire race on a surface of the C-arm facing one of the bearing rollers,

wherein the bearing rollers are actively connected to the guide rail or the wire race.

16. The C-arm x-ray device as claimed in claim 1, wherein the bearing rollers comprise first bearing rollers and second bearing rollers,

wherein the C-arm is rotatably moveably mounted about an orbital axis on the first bearing rollers,

wherein the at least one drive unit comprises an orbital drive unit operable to rotate and brake the C-arm with the first bearing rollers, and

wherein the orbital drive unit is actively connected to the first bearing rollers,

wherein the C-arm is moveably mounted in the horizontal direction on the second bearing rollers,

wherein the at least one drive unit comprises a horizontal drive unit operable to move and brake the C-arm with the second bearing rollers, and

wherein the horizontal drive unit is actively connected to the second bearing rollers.

17. The C-arm x-ray device as claimed in claim 4, further comprising a guide rail or a wire race on a surface of the C-arm facing one of the bearing rollers,

wherein the bearing rollers are actively connected to the guide rail or the wire race.

18. A method for driving and braking a C-arm of a C-arm x-ray device including bearing rollers, on which the C-arm is moveably mounted, the method comprising:

driving or braking the C-arm with the bearing rollers,

wherein the C-arm and the bearing rollers) are actively connected.

19. The method as claimed in claim 18, wherein the C-arm is pivoted about an orbital axis on the bearing rollers,

wherein the method further comprises rotating or braking the C-arm with the bearing rollers, and

wherein the C-arm and the bearing rollers are actively connected.

20. The method as claimed in claim 18, wherein the C-arm is moved horizontally on the bearing rollers, and

wherein the method further comprises moving or braking the C-arm with the bearing rollers.
