Abstract

The invention relates to a support apparatus for the support of a patient lying in the lateral position at the pelvis having a plurality of support rods, in particular precisely three support rods, which each have a known pre-determined length and which are attached adjustably relative to one another to a common support frame such that different spatial configurations of the probe ends of the support rods facing the patient can be set in use in order to make the spatial position of the support points at which the support rods are supported when used on the patient detectable via the free ends of the support rods opposite to the probe ends and serving as detection ends.

Claims

1. A support apparatus for the support of a patient lying in the lateral position at the pelvis having a plurality of support rods (11), in particular precisely three support rods (11), which each have a known pre-determined length and which are attached adjustably relative to one another to a common support frame (13, 15) such that different spatial configurations of the probe ends (17) of the support rods (11) facing the patient can be set in use in order to make the spatial position of the support points at which the support rods (11) are supported when used on the patient detectable via the free ends (33) of the support rods (11) opposite to the probe ends (17) and serving as detection ends.

3. A support apparatus in accordance with claim 1, characterized in that the support rods (11) are made for the probing of pre-determined characteristic points or positions (31) on the pelvis (27), in particular on the anterior side of the pelvis, with the characteristic points or positions (31) preferably defining an anterior pelvic plane which preferably extends at least approximately perpendicular to the median sagittal plane.

4. A support apparatus in accordance with claim 1, characterized in that the support rods (11) are made such that the pelvis (27) of the patient can be mapped by means of the support rods (11) with respect to pre-determined characteristic points or positions (31) on the pelvis (27), in particular on the anterior side of the pelvis (27).

5. A support apparatus in accordance with claim 1, characterized in that the probe ends (17) of the support rods (11) are each provided with a replaceable pressure piston or support foot (25).

6. A support apparatus in accordance with claim 5, characterized in that a plurality of sets of differently sized pressure pistons or support feet (25) are provided.

7. A support apparatus in accordance with claim 1, characterized in that the support rods (11) are each adjustable relative to the support frame (13, 15) in the direction of their longitudinal extents.

8. A support apparatus in accordance with claim 1, characterized in that the support rods (11) extend parallel to one another.

9. A support apparatus in accordance with claim 1, characterized in that the support rods (11) have the same length.

10. A support apparatus in accordance with claim 1, characterized in that the support rods (11) each have a circular cross-section.

11. A support apparatus in accordance with claim 1, characterized in that the support rods (11) are adjustable relative to one another in two directions standing perpendicular to one another.

12. A support apparatus in accordance with claim 1, characterized in that each support rod (11) is attached to a support arm (13) extending perpendicular to the support rod (11), with the support arms (13) being attached to a common support (15) which extends perpendicular both to the support rods (11) and to the support arms (13).

13. A support apparatus in accordance with claim 12, characterized in that the support rods (11) are fixable to the support arms (13) and/or the support arms (13) are fixable to the support (15) in each case by clamping tight in guides (23).

14. A support apparatus in accordance with claim 1, characterized in that a rigid spatial configuration can be established by means of fixing devices (21).

15. A support apparatus in accordance with claim 1, characterized in that the support frame (13, 15) can be fastened to an operating table.

16. A support apparatus in accordance with claim 1, characterized in that the support frame (13, 15) is a component of an operating table.

17. An operating table having a support surface for a patient and having at least one support apparatus for the support of the patient lying in the lateral position at the pelvis, the support apparatus having a plurality of support rods (11), in particular precisely three support rods (11), which each have a known pre-determined length and which are attached adjustably relative to one another to a common support frame (13, 15) such that different spatial configurations of the probe ends (17) of the support rods (11) facing the patient can be set in use in order to make the spatial position of the support points at which the support rods (11) are supported when used on the patient detectable via the free ends (33) of the support rods (11) opposite to the probe ends (17) and serving as detection ends.
