Abstract: The automatic control and administration of program-controlled endoscopic apparatuses allocated to an operation within an operating theater belonging to a clinic region and connected amongst one another by way of a CAN-bus using the standardized layer-seven CANopen protocol for communication among one another and a master computer, is modified so that with the same CAN-bus, a double ring structure, a ring-star structure and a ring-ring structure may be logically formed, permitting peer-to-peer communication of the apparatuses, with which the apparatuses have equality of access to each other and the master computer. The apparatuses, connected to one another via the CAN-bus, of all operating theaters of a clinic communicate with and are centrally controlled by the master computer. All apparatuses are capable of informing the master computer of the occurring process data or parameters. System operation is possible at the master computer as well as at the apparatuses themselves.

For gripping the tissue in a manner such that no injuries occur, according to the invention it is envisaged that the one gripping surface of the one jaw part is curved convexly and the other gripping surface of the other jaw part is curved concavely, in a manner such that with a closed forceps jaw both gripping surfaces bear against one another.

Abstract: A symmetric relay system for endoscopes includes an optically-aligned pair of elongated concavo-convex rod-type lenses formed from crown glass, to the convex end surface of each of which a meniscus-shaped flint lens is cemented. The concave ends of the rod lenses are disposed to face the intermediate images of the relay system, and the convex ends to face the aperture of the relay system. A pair of achromatic lenses, each formed of a pair of lens elements x, y, are disposed adjacent and in optical alignment with the respective concave ends of the rod lenses between the concave rod ends and the intermediate images. Each achromatic lens fulfills the condition n x/ny=vx/vy. Apochromatic glass combinations may be used in the rod lenses to significantly reduce the secondary spectrum.
