Abstract

In an operating table comprising a table column (10) with a column foot (14) and with a column head (16) and also a patient bed (12) which is connectable to the column head (16) and which is pivotable in relation to the table column (10) about at least one axis parallel to the bed plane, the column head (16) has provided on it a guide track (42) which is curved continuously about an axis of curvature and on which a saddle coupleable to the bed (12) is mounted such that it can be adjusted along the guide track (42) by means of a saddle drive.

Claims

1. An operating table comprising:

a table column with a column foot and with a column head; and

a patient bed which is connectable to the column head and which is pivotable in relation to the table column about at least one axis parallel to the bed plane,

wherein the column head has provided on it a guide track which is curved continuously about an axis of curvature and on which a saddle coupleable to the bed is mounted such that it can be adjusted along the guide track by means of a saddle drive.

2. The operating table according to claim 1, wherein the axis of curvature of the guide track lies within the table column.

3. The operating table according to claim 1, wherein the saddle drive comprises at least one saddle-side gear element which can be driven by means of a motor and which is in engagement with a gear element arranged on the head frame.

4. The operating table according to claim 3, wherein the at least one saddle-side gear element is a worm and the gear element arranged on the head frame is a toothed ring fastened to the head frame.

5. The operating table according to claim 1, wherein the column head is adjustable with respect to the column foot by means of a height drive.

6. The operating table according to claim 5, wherein the height drive comprises a telescopic vertical guide and a linear drive.

7. The operating table according to claim 1, wherein the bed is arranged on a connecting frame having coupling elements which are intended for engagement with countercoupling elements arranged on the saddle.

8. The operating table according to claim 7, wherein the bed is pivotable in relation to the table column about at least one axis parallel to the bed plane, and the bed is mounted on the saddle or the connecting frame pivotably about a pivot axis directed transversely to the longitudinal direction of the bed.

9. The operating table according to claim 8, wherein the bed is pivotable in relation to the saddle or connecting frame by means of a bed actuating drive.

10. The operating table according to claim 9, wherein the bed actuating drive comprises at least one drive unit with at least one servomotor which is fastened to the connecting frame or to a bed portion connected to the connecting frame and which is in engagement with an element to be driven, connected in each case to the other part (bed portion or connecting frame).

11. The operating table according to claim 9, wherein the bed comprises at least two bed segments which are connected to one another in an articulated manner about a joint axis coaxial with respect to the bed pivot axis, and the bed actuating drive is designed such that the at least two bed segments can be adjusted together or individually each separately.

12. The operating table according to claim 11, wherein the at least one servomotor of the bed actuating drive is drive-connected in each case via a shiftable coupling to one of the at least two bed segments.

13. The operating table according to claim 12, wherein the at least one servomotor drives in each case a gearwheel which is in engagement with a toothed ring on the respective bed segment.

14. The operating table according to claim 10, wherein a drive unit is provided on both sides of the connecting frame with respect to the bed pivot axis.

15. The operating table according to claim 1, wherein the bed can be coupled to the saddle in such a way that the longitudinal direction of the bed is perpendicular to the axis of curvature of the guide track.

16. The operating table according to claim 1, wherein the bed can be coupled to the saddle in such a way that the longitudinal direction of the bed is parallel to the axis of curvature of the guide track.
