Abstract

An adapter for the releasable and relockable coupling of an endoscope with a camera head has an inner wall and an outer wall that are connected with one another via a connecting wall extending between the inner wall and outer wall at or near their first axial ends, and which inner wall and outer wall are arranged with at least a lateral separation from one another, so that an open clearance results between the inner wall and outer wall on a second axial side that is situated opposite the first axial ends. Furthermore, the adapter comprises a coupling wall that seals a clearance enclosed by the inner wall at or near a second axial end of the inner wall, such that the clearance that is enclosed by the inner wall is open at a first axial side that is situated opposite the second axial end of the inner wall.

Claims

1. An adapter for the releasable and relockable coupling of an endoscope with a camera head, comprising:

an inner wall and an outer wall that are connected with one another via a connecting wall extending between said inner wall and outer wall at or in the area of their first axial ends, and where inner wall and outer wall are arranged with at least a lateral separation from one another so that an open clearance results between said inner wall and outer wall, on a second axial side that is situated opposite the first axial ends, and

a coupling wall that seals a clearance enclosed by the inner wall at or near a second axial end of said inner wall, such that the clearance that is enclosed by the inner wall is open at a first axial side that is situated opposite the second axial end of the inner wall,

wherein one of the clearances is designed for coupling with at least a portion of a distal camera head end

and wherein the other of the clearances is designed for coupling with at least a portion of a proximal endoscope end.

2. The adapter according to claim 1 that is germ-proof between an endoscope that can be arranged on a distal side of the adapter and a camera head that can be arranged on a proximal side of the adapter, in order to thus separate a sterile side from a non-sterile side and to keep the sterile side sterile in this way.

3. The adapter according to claim 1, wherein at least one of the clearances has a cross section varying along the axial direction and/or along a polar angle.

4. The adapter according to claim 1, wherein the adapter is designed to ensure that, in a state in which the adapter is coupled with endoscope and camera head, the parts of the proximal endoscope end and the parts of the distal camera head end that protrude into one of the respective clearances overlap along the axial direction of the adapter by at least 50% of an axial length of at least one of the clearances.

5. The adapter according to claim 1, wherein the coupling wall has at least one opening and/or at least one optical window that is designed to transmit radiation in the optical wavelength range.

6. The adapter according to claim 1,

wherein the clearance formed for the coupling with at least one part of a distal camera head end has at least one coupling face that is designed to couple with at least one coupling face of the distal camera head end, and

wherein the clearance formed for the coupling with at least one part of a proximal endoscope end has at least one coupling face that is designed to couple with at least one coupling face of the proximal endoscope end.

7. The adapter according to claim 6, wherein at least one of the coupling faces is designed to be cylindrical or in the form of a hollow cylindrical shell.

8. The adapter according to claim 6, wherein at least one of the coupling faces is designed to couple at at least two points and has at least two coupling sub-faces.

9. The adapter according to claim 6, wherein at least one of the coupling faces or their coupling sub-faces can be designed so that a cross section varying along the axial direction results in at least one of the clearances.

10. The adapter according to claim 1 that has at least one rotation safeguard that is designed to prevent a rotation of an endoscope and/or camera head coupled with the adapter.

11. The adapter according to claim 1 that has at least one locking device that is designed to lock the endoscope and/or camera head to the adapter so that they are releasable and relockable.

12. The adapter according to claim 1 that has a sterile covering to cover the camera head, wherein the covering is designed to enclose the camera head in a sterile manner.

13. The adapter according to claim 1, wherein the inner wall has coupling faces both on its inside and on its outside, which coupling faces are designed to couple to endoscope and camera head.

14. The adapter according to claim 1 that has

at least one optical conductor to transmit exposure light and/or for optical signal transmission

and/or at least one electrical conductor to transmit electrical signals and/or electrical power

between the proximal side of the adapter and the distal side of the adapter.

15. A use of an adapter according to claim 1 for the coupling of a stereo endoscope with a camera head.
