An illumination device for an endoscope includes illumination means for coupling light into a light guide. The illumination means has an LED matrix array having a plurality of LED pixels forming an emission area, and further includes a light guide port associated with the illumination means for positioning a light-guiding transmission area, which is disposed at an end of the light guide. The device also includes LED pixels configured as sensor elements configured to detect LED pixels of the emission area that are directed at non-light-guiding portions of the light guide, and wherein the device has a control unit which is configured to selectively operate the LED pixels of the LED matrix array for coupling light into the light guide in such a manner that at least some of the LED pixels directed at the non-guiding portions of the light guide in the main emission direction are operated at lower power or deactivated.

Device for the simultaneous fixation of medical instruments, the device having a joint member which has a holding section in the form of a spherical segment, the spherical segment having a continuous cavity along a longitudinal axis, the holding section being subdivided into at least two holding segments perpendicular to the longitudinal axis, and at least two arm elements being arranged on the joint member, the apparatus further comprising a tension ring supported by the support surfaces and a tensioning element configured to press the support segments together, wherein when the support segments are pressed together, the support surfaces press against the tension ring. Furthermore, a system with such a device is revealed.

Device for simultaneous fixation of medical instruments and corresponding system

A device for simultaneous fixation of medical instruments is disclosed, the device comprising a holding portion, a coupling element and a pushing element, wherein the coupling element is configured for the holding portion to be pivoted about a pivot axis, and the pushing element is configured, in a first position, not to exert a force or a first force on the holding portion so that the holding portion can be pivoted, and, in a second position, to exert a second force, which is greater than the first force, on the holding portion so that the holding portion can be pivoted with respect to the first force. is fixed with respect to rotation about the pivot axis. A system with such a device is also disclosed.

A method for testing an optical investigation system, with an imaging device, a video camera and a light source for optical investigation of an object including a reference surface with predetermined optical properties being illuminated with illuminating light from a light source. An image of the reference surface is recorded by the imaging device and the video camera. An operating condition of the video camera that prevails during the recording of the image is recorded. The functionality or another property of the investigation system is determined on the basis of the recorded operating condition.
