Abstract:
1. A stand for a surgical microscope, comprising: a vertical support; the vertical support further comprises at least one horizontal support having a first end facing toward the surgical microscope; a first vertical articulation unit that is connected said first end; a second articulation unit determining an oblique pivot axis and being connected to the first vertical articulation unit; a displacement unit that is attached to the second articulation unit and has multiple degrees of freedom for displacement and balancing of an optics carrier carrying the surgical microscope; at least one pivot support encompassed by the displacement unit; a balancing apparatus for a surgical microscope for balancing an optics carrier held by the pivot support, said optics carrier being rotatable around a first rotational axis in relation to the pivot support; said balancing compensating for the use with and without a microscope holder holding the surgical microscope and with and without add-on units, the balancing apparatus comprising: a Y displacement unit comprising a first slide for displacement of the optics carrier in a Y direction; and a Z displacement unit comprising a second slide for displacement of the optics carrier in a Z direction, wherein the first slide provides for displacement of the optics carrier in a direction transversely to the first rotational axis and transversely to the displacement by the second slide in the Z direction; and the first slide is connected between the pivot support and the second slide and to said second slide such that the weight of the second slide acts as a compensation weight for compensating the weight of the optics carrier with and without the microscope holder holding the surgical microscope and with and without the add-on units via the first rotational axis.
