An electrical feedthrough () is provided for improving the thermal properties and the electromagnetic compatibility (EMC) and also for simplified production of a medical instrument (), in which electrical feedthrough individual contact pins (), which are guided through a glass body () in a housing () of the instrument (), are electrically connected to one another by a pluggable plug element (), preferably in the form of a sheet metal part. Here, the plug element () firstly provides high thermal and electrical conductivity and secondly provides a shielding area that effectively prevents the input coupling of electromagnetic radiation. Preferably, the plug element () is formed in such a way that it independently develops a holding force for securing itself to the contact pins ().

Electrical feedthrough and medical device

An endoscope () has a handle () as well as a probe part () that can be connected thereto via a coupling (), with an illumination device as well as an eye-piece () with an imaging optic being arranged in the handle () and image conductors and light conductors in the probe part (). The coupling includes an image interface and a light interface. In the coupling area, at least one axially engaging guide () as well as bayonet-like engaging coupling parts () are provided, one of which is embodied as a rotational locking part (). In the final locked position the locking part () is secured by a snap. Preferably, the coupling () is provided with an axially engaging guide and additionally axially engaging guides () are provided of the illumination system and the image transmission system, which are particularly arranged side-by-side.

Endoscope

An endoscope () is provided having a handle () and a probe part () that can be connected thereto, with an illumination system comprising at least one light emitting diode () and a video system having an image receiver being arranged in the handle (). A carrier element () made of a heat-conducting material is provided for at least one light emitting diode () inside the handle (), to which the light emitting diode () is directly connected. The carrier element thermally contacts the housing parts and/or installation parts of the handle () and the probe part () for heat conductivity and/or dissipation.
