A carrier system () for a medical apparatus () is disclosed. The carrier system includes rotation joints (). A supply line harness runs in the carrier system () and is run so that it is covered. The rotation joint () includes a tube-shaped holding member on which fingers are formed which hold a rotation joint. A joint element, which is rotatably journalled in a joint receptacle, is provided in the rotation joint (). The joint element has a wave-shaped section which is connected via a connecting section to an annularly-shaped section functioning to accommodate a connecting arm.

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

A joint arrangement for guiding a cable therethrough with a holding body () and a leg () which is rotatably journalled on the holding body () is disclosed. In the joint arrangement, a mechanism for limiting the rotation of the leg relative to the holding body is provided in order to protect a cable passed through the leg and holding body against excessive twisting. The leg () is journalled on the holding body () with a ball joint (). Alternatively or additionally, the joint arrangement includes a swivel joint having a sleeve wherein means for limiting rotation are provided in the form of a stop pin and a stop formed on the sleeve or in a sleeve. Electric operator-controlled elements can be movably mounted on a surgical microscope with the joint arrangement.

The invention is directed to a highly stable CO.sub.2 waveguide laser wherein a resonator block is used which is made of a material having a low thermal expansion coefficient. The resonator block includes a window which is transparent for the wavelength of the laser. Laser reflectors are provided which are mounted by wringing to the resonator body and define a vacuum-tight seal of the resonator body. In this way, the resonator block has a permanently defined adjustment.
