Patent number: 11389265Abstract: A stand for a surgical microscope includes a digiscope and an imaging unit which are interconnected and mounted on an arm of the stand at a joint rotatably about an axis of rotation. The digiscope and the imaging unit are arranged on a bridge such that a fixed spatial relationship, in particular a distance larger than zero between the digiscope and the imaging unit during a relative movement between the digiscope and the patient is maintained. A method for configuring a stand with a bridge includes determining distances between eyes of a surgeon and the imaging unit, between the surgeon and an operating field, between the receptacle of the digiscope and the operating field, and between the imaging unit and the receptacle of the digiscope, and determining a length of the bridge to optimally set a distance from the surgeon to the patient and the imaging unit for the surgeon.Type: GrantFiled: May 8, 2020Date of Patent: July 19, 2022Assignee: Carl Zeiss Meditec AGInventors: Joachim Steffen, Daniel Kolster, Andrè Mueller
