Abstract

The invention concerns a stand (1) for a surgical microscope, having a stand column (2) and having at least one pivot arm (3). The pivot arm (3) is arranged pivotably about a vertical rotation axis (5) by way of a rotary bearing (4). A tilting device (6) for adjustably tilting the rotation axis relative to the column is provided, wherein the tilting device (6) includes a bearing shaft (8) supported by the column and defining a substantially horizontal tilting axis, and an adjustment housing (7) mounted on the bearing shaft (8) for rotation about the tilting axis. The rotary bearing (4) is carried by the adjustment housing (7).

Claims

1. An apparatus (1) for a surgical microscope comprising:

a column (2);

a pivot arm (3);

a rotary bearing (4) mounting the pivot arm on the column for rotation about a substantially vertical rotation axis (5);

a tilting device (6) for tilting the rotation axis relative to the column, the tilting device (6) including a bearing shaft (8) supported by the column and defining a substantially horizontal tilting axis, and an adjustment housing (7) mounted on the bearing shaft (8) for rotation about said tilting axis; and

a trunnion (9) fixed to said adjustment housing (7).

2. The apparatus (1) as defined in claim 1, wherein the adjustment housing (7) is arranged in the column (2).

3. An apparatus (1) for a surgical microscope comprising:

a column (2);

a pivot arm (3);

a rotary bearing (4) mounting the pivot arm on the column for rotation about a substantially vertical rotation axis (5);

a tilting device (6) for tilting the rotation axis relative to the column, the tilting device (6) including a bearing shaft (8) supported by the column and defining a substantially horizontal tilting axis, and an adjustment housing (7) mounted on the bearing shaft (8) for rotation about said tilting axis;

wherein the adjustment housing (7) is arranged in the column (2); and

wherein the tilting device (6) further includes two adjusting screws (10a;

10b) arranged opposite one another and associated with the adjustment housing (7).

4. The apparatus (1) as defined in claim 3, wherein the adjusting screws (10a;

10b) extend parallel to the rotation axis (5).

5. The apparatus (1) as defined in claim 4, wherein a trunnion (9) is guided between the two adjusting screws (10a;

10b).

6. The apparatus (1) as defined in claim 3, wherein a trunnion (9) is guided between the two adjusting screws (10a;

10b).
