Abstract

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.
