Abstract: A resectoscope has an elongated shaft tube, an elongated optic arranged therein with a lens at the distal end and an electrode assembly, wherein the electrode assembly in turn includes an electrode arranged at the distal end of the arms of a fork assembly, which are arranged on opposing sides of the lens and are brought together in a transition region to an electrode shaft, wherein the electrode assembly can be extended in the longitudinal direction by a stroke length from a first position, in which the electrode is arranged inside the shaft tube in front of the lens, into a second position in which the arms of the fork assembly protrude out of the shaft tube. The length of the arms of the fork assembly is thereby greater than 1.2 times the stroke length. The electrode assembly is configured correspondingly.

Abstract: A housing for accommodating optical and electronic components of a video camera of a medical video endoscope. The housing including: a first housing part, a second housing part, the housing parts assembled together to form inner chambers for mounting the optical and electronic components and an axial passage for optically connecting the inner chambers; a window disposed in an end opening in the assembled housing parts, electrical connectors disposed in a wall in the assembled housing parts, wherein, in an unassembled configuration, the inner chambers are accessible from a surface substantially transversely to a longitudinal axis of the housing parts, and the first and second housing parts are configured to mate with each other in such a way that the inner chambers are hermetically sealed from an exterior of the assembled first and second housing parts.

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.

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 video endoscope including: a tube forming an interior, a window formed at a distal end of the tube; an image sensor; a support in the interior for supporting the image sensor, said image sensor viewing through the window; a conductor arranged on the support, the conductor electrically connecting the image sensor, and a closing wall at a proximal end of the tube through which a pin extends, said pin being in contact with the conductor on the support, wherein the support abuts an inner face of the closing wall such that a surface region of the support on which the conductor is mounted contacts the closing wall at an angle at the point where the pin is located such that a portion of the pin protrudes into the interior and rests in a parallel manner on the surface region of the support and makes contact with the conductor.

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.
