Abstract: The invention relates to a stand (10) for holding at least one medical device (W1 to W3), which encompasses a stand foot (6) having multiple casters (16) for displacement of the stand (10). The stand (10) has a sensor unit (22) for ascertaining a displacement motion of the stand (10), a drive unit (18) for driving at least one of the casters (16), and a control unit (20) for controlling the drive unit (18). The control unit (20) applies control to the drive unit (18) in such a way that the latter assistively drives the at least one caster (16) only when the sensor unit (22) detects a displacement motion of the stand (10).

Abstract: The present invention relates to a system for displaying stereoscopic microscope images, including a display screen (130) and a computer device (120) for computing or providing stereoscopic images from monoscopic images. The computer device (120) has an evaluator configured to evaluate the stereoscopic perceptibility of the computed or provided stereoscopic images and, in case that it is determined that at least one region of a stereoscopic image cannot be stereoscopically perceived, for replacing the computed or provided stereoscopic image with a monoscopic image in this region.

Abstract: The present invention relates to a special-illumination surgical stereomicroscope (1) for observing an object (6) in an object field (15) under special illumination, the special-illumination surgical stereomicroscope including a surgical illumination light source (7; 7a) for illuminating the object field (15) via an illumination beam path (11) and further including a special-illumination light source. The special-illumination light source is adapted for observation of stimulated emission and includes an excitation light source (8a) for specific excitation of a substance contained in the tissue of the object (6) via an excitation beam path (12a), and a stimulation light source (8b) for stimulating the emission of light from the previously excited substance via a stimulation beam path (12b). A common observation beam path (14) is provided for guiding the light generated by stimulated emission and the reflected surgical illumination light.

Abstract: The present invention relates to an attachment module (100) for a surgical microscope (10), the attachment module (100) being insertable into a main optical path between an objective (11) of the surgical microscope and an object (O) being observed, and including: a multi-photon fluoroscope (110) including a light source (111) for emitting excitation light, a scanning device (112) for directing the excitation light onto the object (O), and a detector (113) for detecting fluorescent light emitted from the object (O); and input coupling optics (120) for reflecting the excitation light from the scanning device onto the object (O).

Abstract: A stand (10, 100) for holding a medical device (W1, W2, W3) includes a stand foot (9) and a carrier unit (1) connected to the stand foot rotatably about an axis (S), the medical device being mountable on the carrier unit. The stand also includes a counterweight (W4) to compensate for the torque about the axis produced by the medical device and the carrier unit, a first receiving unit (6, 102) at a first location for receiving at least a portion of the counterweight, and a second receiving unit (7, 104) at a second location for receiving at least another portion of the counterweight. Upon a change in torque about the axis, a proportion of the counterweight received by the first receiving unit is increasable by a compensation value, and that proportion of the counterweight which is received by the second receiving unit is reducible by that compensation value.

Abstract: A surgical microscope system (100) for ophthalmology, in particular for cataract surgery, comprising a surgical microscope (10) having an optical viewing unit (13), is proposed, in which an optical coherence tomograph (20) is set up to scan at least a region of a lens (53) of an eye (50) and to generate scan values, and in which a detection unit (30) is set up to generate, on the basis of the scan values, diagnostic data that correspond to light-reflecting structures in the scanned region of the eye (50) and that derive from a plane of the eye (50) that corresponds to an object plane of the surgical microscope (10).

Abstract: The invention relates to a stand for a surgical microscope (28) having a pivotable carrier arm (4). The latter is modifiable in length as a function of its pivot angle (29). It carries a microscope holder (6), pivotable in at least one plane, at the distal end of carrier arm (4), the angular position (21; 24) of the microscope holder (6) being definable with reference to the carrier arm (4; 34) according to a further development; and a motorized drive, which engages on the one hand on the carrier arm and on the other hand on the microscope holder (6), and in the context of operation defines the angular position (21; 24) in remotely controlled fashion and/or automatically.

Abstract: The invention relates to a stand, in particular to a stand for a surgical microscope, having a pivotable carrier arm (4) and having a microscope holder (6) pivotable in a plane at the distal end of the carrier arm (4), the angular position (21; 24) of the microscope holder (6) being definable with reference to the carrier arm (4), and having a motorized drive that engages on the one hand on the carrier arm and on the other hand on the microscope holder (6), and in the context of operation defines the angular position (21; 24) in remotely controlled fashion and/or automatically. This construction eliminates complex parallelogram supports and angle transfer elements that link the tilt of the microscope holder (6) depending on the pivot position of the carrier arm (4). The construction thus becomes simpler and lighter, and less dependent on production tolerances.
