Abstract: A hermetic feedthrough for a video endoscope for feeding electrical lines from a first partial space into a second partial space, the hermetic feedthrough including: a partition wall for hermetically sealing the two partial spaces, and a printed circuit board produced by a thin-film technique and in which the electrical lines are embedded in a plastic, is cast with a plastic compound in a mold and post-cured, wherein the plastic compound forms the partition wall.

Abstract: A video endoscope including: an elongated housing; an image sensor unit arranged in the elongated housing; an optical transmitting unit arranged in the elongated housing and connected to the image sensor unit; and a through contact device, wherein the optical transmitting unit is arranged at a proximal end of the elongated housing on the through-contact device, the through-contact device penetrates through a wall of the elongated housing and the through-contact device is arranged such that it is mounted in a hermetically sealed manner in the wall of the elongated housing.

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.
