Abstract

An x-ray arm of an x-ray system is controlled with the aid of a joystick. If there is a threat of a collision between the x-ray arm and an obstacle, for example a patient bed, a force is exerted on the guide element which generates a warning signal perceptible in a tactile manner, which indicates to the user the danger of a collision.

Claims

1-9. -9. (canceled)

10. A device for medical provision of a patient, comprising:

a medical unit movable relative to a patient bed;

a position sensor that records the position of the medical unit;

a supervision unit in communication with the position sensor that monitors the movement of the medical unit and generates a warning signal to the guidance device if the distance between the medical unit and an obstacle is near collision; and

a guidance device that controls the movement of the medical unit via a user input, comprising a user operated guidance element that exerts a vibratory warning force perceivable in a tactile manner by the user based on the warning signal from the supervision unit.

11. The device in accordance with claim 10, wherein the setting device causes the guidance element vibrate when the distance of the medical unit to the obstacle is near collision.

12. The device in accordance with claim 10, wherein the vibration amplitude increases as the distance of the medical unit to the obstacle decreases.

13. The device in accordance with claim 12, wherein the setting device is an inhibiting device that exerts an inhibiting force which acts against the force exerted by the user on the guidance element.

14. The device in accordance with claim 13, wherein the inhibiting force exerted by the inhibiting device increases as the distance of the medical unit to the obstacle decreases.

15. The device in accordance with claim 14, wherein the guidance device applies a control signal generated by the guidance element to the monitoring device.

16. The device in accordance with claim 15, wherein the medical unit is a movable x-ray arm having an x-ray source and an x-ray detector arranged at opposite ends of the arm.

17. The device in accordance with claim 16, wherein the medical unit is a magnetic navigation system with a magnet mounted on a support arm.

18. The device in accordance with claim 10, wherein the guidance element is a joystick or a track ball.

19. A medical examination device, comprising:

an patient examination table that supports a medical patient;

a medical unit that is movable relative to the examination table and provides or assists in providing a medical procedure;

a position sensor that records the position of the medical unit;

a supervision unit in communication with the position sensor that monitors the movement of the medical unit and generates a warning signal to the guidance device if the distance between the medical unit and an obstacle is near collision; and

a guidance device that controls the movement of the medical unit via a user input, comprising a user operated guidance element that exerts a vibratory warning force perceivable in a tactile manner by the user based on the warning signal from the supervision unit, and applies a control signal generated by the guidance element to the monitoring device.

20. The device in accordance with claim 19, wherein the vibration amplitude increases as the likelihood of a collision with an obstacle increases.

21. The device in accordance with claim 20, wherein the functional unit is a movable x-ray arm having an x-ray source and an x-ray detector arranged at opposite ends of the arm.

22. The device in accordance with claim 21, wherein the medical functional unit is a magnetic navigation system with a magnet mounted on a support arm.

23. The device in accordance with claim 19, wherein the guidance element is a joystick or a track ball.
