A tube of a surgical microscope has a base part, intermediate part pivotable about a rotational axis on the base part, and an ocular part pivotable about a rotational axis on the intermediate part. The imaging beam path is guided through the base part, intermediate part and pivotable ocular part. The tube has a tube lens system which transfers a parallel imaging beam path into an intermediate image. The parallel imaging beam path enters via an opening in a connecting piece of the base part. The tube has a first displaceable mirror element movable about the rotational axis on the base part. The tube has a further displaceable mirror element movable on the intermediate part about the rotational axis. The first mirror element directs the imaging beam path to the further mirror element. The first mirror element and further mirror element are mounted in the imaging beam path between a lens unit having positive refractive power and a lens unit having negative refractive power.

Adapter assembly for mounting a camera on a surgical microscope

An adjusting device () is suitable especially for use on a stand () for a surgical microscope (). The adjusting device () makes it possible to move the surgical microscope () in a plane () perpendicular to the optical axis () of the surgical microscope (). For this purpose, a transmission is provided in the adjusting device () which includes a coupling plate which is operatively connected to two force-transmitting elements. When this transmission is moved, at least one of the force-transmitting elements rolls off on the coupling plate. Alternatively, this transmission can be built up as a four-point linkage chain or contain a rhombic mechanism or lever mechanism. It is also possible to configure the transmission with belt elements or to configure the same as an eccentric arrangement having two offset rotation centers.

Adjusting device

In a holding arrangement () for a medical-optical instrument (), an electric motor is provided in a rotational joint () to compensate a load torque occurring in this rotational joint. This electric motor is supplied with current in correspondence to a detected position of the rotational joint (). A current control curve required for this purpose is stored in a memory. This current control curve can be determined in that the rotational joints are deflected with the electric motor into predetermined positions and the current demand needed therefor is detected.
