Abstract: An endoscope, especially a mediastinoscope, includes an elongated shaft and a head piece situated at a proximal end section of the shaft, wherein a heat source is arranged in the head piece. At least one heat pipe extends inside the shaft, wherein a proximal end section of the at least one heat pipe is thermally coupled to the heat source and the endoscope includes an optical system which is closed by a cover glass arranged in a distal end section of the shaft. The heat source is a light source for generating an illumination radiation. The at least one heat pipe extends in the distal direction as far as the distal end section of the shaft, and at least one distal end section of the heat pipe is thermally coupled to the distal end section of the shaft.

Abstract: A medical instrument for providing access to the interior of the body comprises a shaft having an elongated base body and a handle. The base body extends between a distal end and a proximal end of the shaft. The handle is coupled to the base body of the shaft at the proximal end. The shaft defines at least a first channel and a second channel that extend through the shaft. The first channel provides a passage for surgical instruments through the shaft. The second channel is adapted to accommodate an observation optics. The second channel is adjacent to at least one secondary channel that is connected to the second channel.

Abstract: An imaging medical instrument such as an endoscope, an exoscope or microscope having a shaft, in which an optical fiber bundle extends from the proximal to the distal end for illuminating field and in which a lens system is arranged for transmitting an image of the field. A light source inputs coupling light into the one proximal end of the optical fiber bundle with a multiplicity of selectively actuatable individual light sources arranged in an array-like manner, with a camera for capturing the transmitted image of the field of view and with a control unit for selectively actuating the individual light sources of the light source for adapting the illumination field. Here, the illumination field has a different form to the field of view.

Abstract: An optical instrument for capturing stereo images includes two optical devices for producing a real image in each case, two carriages, which are each movable along a predetermined path relative to one of the optical devices, two image sensors, each with a light-sensitive surface for capturing the respective real image, with one of the image sensors in each case being fastened to the carriage, and one reflecting surface in the beam path between the optical device and the image sensor in each case.
