Abstract:
1. A microscope stand for supporting a surgical microscope, the stand comprising: a stand interface; a pivot axis associated with the stand interface; a pivot support including a first end and a second end; a mount attached to the first end of the pivot support and adapted to mount the microscope to the microscope stand; a C-slide displacement assembly provided on the second end of the pivot support for balancing the microscope about the pivot axis; and a support axis held by the C-slide displacement assembly; the pivot support being pivotable about the support axis; the C-slide displacement assembly being pivotable about the pivot axis relative to the stand interface; and a parallel guide mechanism connecting the pivot support to the stand interface and allowing the pivot support to perform a circular motion in a vertical plane, wherein the parallel guide mechanism includes a cross-lever linkage which is rotatable about a cross-lever axis extending centrally between and parallel to the support axis and the pivot axis and which is connected to both the stand interface and the pivot support in such a way that the cross-lever linkage transmits its own pivotal state simultaneously and equally to the stand interface and to the pivot support, and wherein the cross-lever linkage includes a cross lever supported for rotation about the cross-lever axis, the cross lever being articulated at one end thereof to the stand interface via a first connecting element and at another end thereof to the pivot support via a second connecting element.
