An apparatus for fluorescence diagnosis comprises an illumination system for illuminating a target area. The illumination system has a light source designed for generating white light and an illumination path. The apparatus further comprises an observation system for observing the target area, which has an observation path. The illumination system has a first illumination mode, in which an illumination spectral filter is arranged in the illumination path, which filter is transmitting in an excitation spectral range and substantially non-transmitting in the spectral range on the long-wavelength side outside of the excitation spectral range, and said illumination system has a second illumination mode, in which the illumination spectral filter is not arranged in the illumination path. An observation spectral filter is arranged in the observation path in the first illumination mode and in the second illumination mode, which filter is substantially non-transmitting in the excitation spectral range and transmitting in the spectral range on the long-wavelength side outside of the excitation spectral range. The observation spectral filter additionally is transmitting in the spectral range on the short-wavelength side outside of the excitation spectral range.

A diagnosis device having an illumination system configured to produce white light along an illumination path, an observation system for observing the target region in a white-light and fluorescence mode, the observation system having an observation path having at least one first image sensor for receiving a white-light image and at least one second image sensor for receiving a fluorescence image, an observation spectral filter in the observation path are configured such that light in the spectral range of the fluorescence can be fed to the second image sensor while light in the spectral ranges outside of the fluorescence is blocked. An illumination spectral filter is arranged in the illumination path and having a characteristic of the observation spectral filter such that the target region is illuminated with the whole spectral range of the white light with the exception of the spectral range of the fluorescence to be observed.

The present invention relates to a system for the central control of devices used during an operation, including a first control unit for control of the devices. The system is characterized in that a second control unit is provided which is connected to the first control unit for exchange of information. The first control unit may be embodied as closed system for control of at least those devices which carry out safety-related functions (safety-related devices), and the second control unit may be embodied as open system for control of the remaining devices which carry out non safety-related functions (non safety-related devices). The invention further relates to a method for the central control of devices.
摘要:
A system for orientation assistance and display of an instrument that is inserted or present in the natural or artificially produced hollow cavity (human, animal, object), and that is equipped with one or more sensor units. Multiple measurements of the 3D position of the instrument equipped with one or more sensor units are performed by positioning a measuring system, so that a precise orientation and positioning of the instrument in the body can be computed. The 3D position data are used to compute a virtual image of the instrument synchronously. The virtual images are then either projected directly in exact position onto the body surface of a person or combined in a body surface image (real video camera image of the patient) onto a monitor or superimposed (virtual or augmented reality). The system is especially appropriate for displaying for a user a medical instrument, such as a catheter or a rigid or flexible endoscope, in the body of a person in real time, extracorporeally and in correct position.
摘要:
A video endoscope has an endoscope part having a central image signal conductor, at least one optical waveguide, and a light supplying part which can be coupled to a proximal end of said endoscope part. The light supplying part has a central image signal conductor connection at a distal end thereof, and a light supply arranged coaxially around said central image signal conductor connection. The light supply has a plurality of light-emitting elements, each of said light-emitting elements can be supplied by means of a switchable semiconductor light source. Position sensors are arranged in an area of said light-emitting elements, and position indicators are arranged in an area of said optical waveguide. A position of said position indicators can be detected by said position sensors when said endoscope part and said light supplying part are coupled. Based on a detection of said position indicator, at least those light-emitting elements lying opposite to said optical waveguide are activated.
