The invention relates to an arrangement for at least partially compensating a torque caused by gravitational forces acting on a mass body (), which is rotatably supported on an axis of rotation (). The arrangement includes a gas pressure spring () for providing a linear force. This linear force is transformed into a torque by means of a converter unit (). The mass body () and the converter unit () can be coupled to each other in a way which allows for adjusting the amplitude and the phase of a compensating torque.

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.

The handle of the handle assembly can be detachably mounted in at least two different orientations relative to a defined apparatus axis. Furthermore, actuating elements of the particular instrument can be reached without difficulty via a suitable cutout in the handle without it being necessary for the operator to significantly change the manual hold on the handle. The handle assembly is especially advantageous on a surgical microscope.
