Abstract: The invention relates to an electrical connection piece for a video endoscope having a hermetically closed video unit in a shaft of the endoscope, a video endoscope, and a method for producing an electrical connection in a video endoscope. The electrical connection piece according to the invention includes an at least partially flexible printed circuit board having conductive tracks, wherein the printed circuit board has a base surface with openings for contact pins of a hermetic feedthrough, and a flexible first arm and a flexible second arm that branch off in different, in particular opposite, directions from the base surface, wherein the first arm and the second arm each have a flat end surface at the respective ends facing away from the base surface, wherein the conductive tracks extend between the openings on the base surface and electrical contacting surfaces in the end surfaces.

Abstract: A video endoscope with sideways viewing direction including an endoscope shaft having a jacket tube, an entry window joined hermetically to the jacket tube at the distal end of the jacket tube, a sideways viewing optical subassembly and a sensor module having an optical sensor, wherein the sensor module is disposed on a distal side of a longitudinally extended sensor module carrier that is rotatably mounted with respect to the jacket tube. In the video endoscope, the sideways viewing optical subassembly can be formed as an attachment which can be plugged distally onto the sensor module and/or the sensor module carrier and which is rotatably mounted with respect to the sensor module and/or the sensor module carrier, wherein the attachment has at least one lock which interacts with at least one corresponding lock on the jacket tube, such that the attachment is rotationally fixed with respect to the jacket tube.

Abstract: A surgical instrument, such as an endoscope, having a hermetically sealed housing for accommodating, optical and/or electrical devices therein. The housing having a wall with a via provided in the wall to electrically connect an electrical contact formed on the inside of the wall with an electrical contact formed on the outside of the wall, wherein the via has a penetration in the wall, and the penetration is filled with a filling material to form a hermetically sealed housing, wherein the electrical contacts are formed as at least one electrically conductive conductor path on the inside of the wall and on the outside of the wall, wherein one conductor path on the inside of the wall, and one conductor path on the outside of the housing are connected to each other by means of the via, and wherein the filling material of the via consists of metal or solder.
