Abstract

An endoscope is provided with an endoscope shaft and a main body connected to the endoscope shaft. The endoscope includes a camera connection to which an optical recording device can be mechanically fixed. The main body is electrically conductive. The camera connection includes an electric insulating body that electrically insulates an optical recording device, mechanically fixed to the camera connection, from the main body.

First claim

The invention claimed is:

1. An endoscope, comprising:
an endoscope shaft; and
a main body connected to the endoscope shaft, the main body including a camera connection,
wherein the camera connection is configured to mechanically fix an optical recording device to the main body,
wherein the main body is electrically conductive,
wherein the camera connection includes an electric insulating body configured to insulate the optical recording device from the main body when the optical recording device is mechanically fixed to the camera connection, and
wherein the camera connection includes a metallic ring nut with an external thread onto which a corresponding internal thread of the optical recording device can be screwed.

2. The endoscope according to claim 1 , wherein the camera connection is disposed at the proximal end of the endoscope.

3. The endoscope according to claim 2 , wherein the electric insulating body includes at least one ring which can be rotated relative to the main body, and the ring nut is connected to the at least one ring in rotation-resistant manner.

4. The endoscope according to claim 1 , wherein the camera connection is rotatable relative to the main body.

5. The endoscope according to claim 1 , wherein the electric insulating body includes at least one ring which can be rotated relative to the main body, and wherein the ring nut is connected to the at least one ring in a rotation-resistant manner.

6. The endoscope according to claim 1 , wherein the electric insulating body is formed of a plastic material.

7. The endoscope according to claim 1 , wherein the electric insulating body is formed of polyetheretherketone.

8. The endoscope according to claim 1 , wherein imaging optics are disposed in the endoscope shaft and in the main body, the imaging optics configured to display an object in front of the endoscope shaft as an image in a focusing plane which lies behind the end of the main body facing away from the endoscope shaft.

9. The endoscope according to claim 8 , wherein the imaging optics are disposed in a hermetically sealed inner space of the endoscope.

10. The endoscope according to claim 1 , wherein the endoscope is able to be autoclaved.
