摘要:
The present invention relates to a surgical microscopy system, comprising a surgical microscope, a stand comprising a base and a plurality of pivotally connected arms, the surgical microscope being mounted to one of the arms, wherein the pivotally connected arms are arranged to be movable with respect to each other such that the surgical microscope is movable relative to the base, and wherein a conventionally provided lead is replaced by one or more leads fulfilling the function of the single lead together. The present invention also relates to a surgical microscopy system, wherein data or/and energy is transmitted to the surgical microscope by wireless transmission.
摘要:
A microscopy system for eye surgery with an objective lens is suggested, which provides a retroillumination system to generate a so-called red reflex illumination during an eye-surgical treatment, in particular during a cataract operation.

A stereomicroscopy system and method for generating at least a pair of representations of an object 7 for observation a user 9 are provided, comprising a detection system 15 for providing radiation data corresponding to detected radiation emanating from a region 17 of the object, a position detection apparatus 29 for detecting a position of the user, a location determination device 23 for determining a first and a second location in an object coordinate system 25, an image data generation device 23 for generating image data from the radiation data for a first representation and a second representation representing the region of the object viewed from the first and second locations, respectively, and a display apparatus 75 for displaying the first representation for a left eye of the user and for displaying the second representation for a right eye of the user as a function of the image data.
摘要:
A coherence microscope has a divider (3) that divides light emitted by a light source (1) into measurement light, which is supplied to and reflected by a specimen (13), and reference light. A superimposition device (25, 31) superimposes the measurement light reflected by the specimen (13) with the reference light. A short sensor array (41) detects the light resulting from the superimposition and permits a read-out rate of at least about 60 kHz. The superimposition device has an emission device (25, 31) for emitting the measurement light and the reference light arranged to effect extensive irradiation of the sensor array (41) with superimposed light. The ratio of distances covered by the measurement light and the reference light from the emission device (25, 31) to impingement points on the sensor array (41) varies in the portion of the sensor array (41) that is irradiated with superimposed light.

An optical observation apparatus includes: an optical system which produces an image of an object being observed and a video device (7) for recording the image and producing an image signal. The video device (7) includes a first memory (71) for temporarily storing the image signal, a second memory (73) in data communication (77) with the first memory (71), and a control device (75) in communication (76A, 76B) with both memories (71, 73) for controlling the storage procedure in the first memory and data transfer from the first to the second memory. The control device (75) controls the storage procedure and the data transfer so that overwriting of such data already stored for a given period of time in the first memory (71) is effected and that transfer of the content of the first memory (71) to the second memory (73) takes place as a reaction to a trigger signal.

Improvements in respect of performing cataract surgery, and the result thereof, by application of a laser system. A device for cataract surgery, includes a surgical microscope or stereo microscope and a laser source. A module, consisting of a laser-coupling/deflecting unit, a laser-scan unit, and a focusing unit, can be attached to the surgical microscope or stereo microscope, in which at least one of these units can selectively be introduced between the surgical microscope and eye, and in which the focusing unit can scan a depth-of-focus range of greater than 1 mm.
摘要:
A tooth is irradiated with light (5), in particular with visible light for identifying tooth-coloured tooth filling residues (3) of the tooth. The light with which the irradiation procedure is effected includes at least one wavelength component that is absorbed or scattered by the tooth filling material differently from the tooth material in such a way that the tooth filling material differs from the tooth material in respect of its brightness or in respect of its colour. Thus the identification of tooth filling residues (3) can be effected in such a way that the dentist can recognise the tooth filling residues (3) with the naked eye, or possibly with the assistance of simple technical aids such as for example a colour filter.
