Abstract

An optical observation instrument according to the invention, in particular a surgical microscope or exoscope, comprises an optics unit with an objective arrangement and at least one electronic image recorder, wherein the optics unit has a first stereo channel with a first beam path and a second stereo channel with a second beam path for recording a stereo image of an object field with the at least one electronic image recorder and wherein the first and the second beam path extend through the objective arrangement. Further, the observation instrument comprises a retaining apparatus which comprises a retaining bracket, which engages over the optics unit, wherein the retaining bracket comprises an operating device with a number of operating elements for controlling a retaining arm, to which the retaining apparatus is connectable.

First claim

The invention claimed is:

1. An optical observation instrument, comprising:
an optics unit with an objective arrangement and at least one electronic image recorder, wherein the optics unit has a first stereo channel with a first beam path and a second stereo channel with a second beam path configured to record a stereo image of an object field with the at least one electronic image recorder and wherein the first and the second beam path extend through the objective arrangement, and
a retaining apparatus, on which the optics unit is mounted, wherein the retaining apparatus comprises a retaining bracket, the retaining bracket being movably connected to the optics unit at
both a distal end and a proximal end of the optics unit and, at each of the distal and the proximal end of the optics unit, the optics unit is movably connected to the retaining bracket with respective bearings, a first bearing of the respective bearings being located at the distal end of the optics unit and a second bearing of the respective bearings being located at the proximal end of the optics unit, the optics unit rotatable via the respective bearings around a center axis, the center axis between optical axes of the first and the second stereo channel and running through a center of the first and second bearings, wherein the retaining bracket comprises an operating device with a number of operating elements configured to control a retaining arm, to which the retaining apparatus is connectable.

2. The optical observation instrument as claimed in claim 1 , wherein the retaining apparatus is embodied to be arranged in rotatable and/or longitudinally displaceable fashion on the retaining arm.

3. The optical observation instrument as claimed claim 1 , wherein the retaining bracket engages over the optics unit in a direction approximately parallel to the stereo channels or approximately parallel to the center axis between the stereo channels.

4. The optical observation instrument as claimed in claim 1 , wherein a section of the retaining bracket between the two ends of the retaining bracket is spaced apart from the optics unit and configured to be grasped by a human hand.

5. The optical observation instrument as claimed in claim 4 , wherein the operating device is arranged on the retaining bracket in the region of the section.

6. The optical observation instrument as claimed in claim 1 , wherein the optics unit is mounted on the retaining bracket so as to be rotatable about a first axis of rotation.

7. The optical observation instrument as claimed in claim 6 , wherein the retaining apparatus is configured such that a position and/or orientation of the optics unit is fixable by one or more of nonpositive engagement, frictional engagement, interlocking engagement, in electromagnetic fashion and by a motor.

8. The optical observation instrument as claimed in claim 1 , wherein the optical observation instrument has a viewing direction that is angled in relation to the axis of the objective arrangement and comprises a deflection element which is arranged on the object side of the objective arrangement and which is configured to deflect the first and the second beam path into the objective arrangement, wherein the optical deflection element is retained at an object-side end of the retaining bracket.

9. The optical observation instrument as claimed in claim 1 , wherein the operating device comprises at least one element configured to release and lock the retaining arm.

10. The optical observation instrument as claimed in claim 9 , wherein the element for releasing and locking the retaining arm is arranged on a side of the retaining bracket facing the optics unit.

11. The optical observation instrument as claimed in claim 9 , wherein the retaining bracket additionally comprises a finger rest on a side opposite the element for releasing and locking purposes.

12. The optical observation instrument as claimed in claim 1 , wherein the operating device comprises at least one element configured to control a camera, a light source or a data processing installation.

13. The optical observation instrument as claimed in claim 1 , wherein the elements are partly arranged on a side of the retaining bracket facing away from the optics unit.

14. The optical observation instrument as claimed in claim 1 , wherein the operating device is electrically coupled to an interface of the retaining bracket for connection to the retaining arm.

15. The optical observation instrument as claimed in claim 1 , wherein the optical unit is rotatable around an axis parallel to the retaining bracket.

16. The optical observation instrument as claimed in claim 1 , wherein the instrument is a surgical microscope or exoscope.

17. An optical observation surgical device comprising:
an optics housing with an objective arrangement,
at least one electronic image recorder, wherein the optics housing has a first stereo channel with a first beam path, and a second stereo channel with a second beam path allowing recording a stereo image of an object field with the at least one electronic image recorder, wherein the first and the second beam path extend through the objective arrangement, and
a retaining apparatus, to which the optics housing is mounted, the retaining apparatus comprising a retaining bracket, the retaining bracket connected to the optics housing, the retaining bracket fixed to a distal end and a proximal end of the optics housing with bearings, the optics housing rotatable around a center axis, the center axis located between optical axes of the first and the second stereo channel and running through a center axis of rotation of the bearings, wherein the retaining bracket comprises at least one operating device with one or more operating elements configured to control a retaining arm to which the retaining apparatus is connectable.

18. An optical observation instrument, comprising:
an optics unit with an objective arrangement and at least one electronic image recorder, wherein the optics unit has a first stereo channel with a first beam path and a second stereo channel with a second beam path configured to record a stereo image of an object field with the at least one electronic image recorder, and wherein the first and the second beam path extend through the objective arrangement, and
a retaining bracket, on which the optics unit is mounted, wherein the optics unit is rotationally connected to the retaining bracket at both a distal end and a proximal end of the optics unit and, at each of the distal and the proximal end of the optics unit, the optics unit is rotationally connected to the retaining bracket with respective bearings, a first bearing of the respective bearings being located at the distal end of the optics unit and a second bearing of the respective bearings being located at the proximal end of the optics unit, the optics unit rotatable via the respective bearings around a center axis, the center axis located between optical axes of the first and the second stereo channel and running through a center of the first and second bearings, wherein the retaining bracket comprises an operating device with a number of operating elements configured to control a retaining arm, to which the retaining apparatus is connectable.
