Patent number: 10859804Abstract: A system combines an operating microscope and an endoscope. The operating microscope includes a light source with a first color temperature that illuminates a first portion of an operating field. The endoscope includes an LED light source with a second color temperature that illuminates a second portion of the operating field, wherein the two color temperatures are matched to one another in such a way that, in optical and/or digital imaging of the operating microscope and/or in optical and/or digital imaging of the endoscope, there are no perceivable color differences in portions of the operating field that are illuminated and observed jointly by the operating microscope and the endoscope.Type: GrantFiled: April 16, 2018Date of Patent: December 8, 2020Assignee: Carl Zeiss Meditec AGInventors: Helge Jess, Martin Fanenbruck, Roland Guckler

Patent number: 10842347Abstract: A medical apparatus includes a control device, a motion sensor, via which a motion value is determinable, a position sensor, via which an angular position in space is detectable, and a time measuring device, via which a time interval is determinable. The control device is embodied in such a way that a switch-off signal is producible if, during the entire time interval, the motion value remains below a threshold and, at the same time, the position sensor detects an inclination angle relative to a repository plane that lies in a defined repository angle range.Type: GrantFiled: September 29, 2017Date of Patent: November 24, 2020Assignee: Carl Zeiss Meditec AGInventors: Roland Guckler, Martin Fanenbruck, Helge Jess, Peter Nakaji

A display device represents a first image recorded by the first image recording device in a first orientation and a second image recorded by the second image recording device in a second orientation. The endoscope includes a motion sensor connected to a control unit to determine an angular position of the probe of the endoscope in space. The control unit determines an angular position of the probe of the endoscope relative to a first viewing axis to permit the second orientation of the second image to be alignable depending on an angular position of the probe relative to the first viewing axis.Type: ApplicationFiled: September 22, 2018Publication date: March 28, 2019Inventors: Martin Fanenbruck, Helge Jess, Roland Guckler

Patent number: 9095255Abstract: Functional tissue areas in a tissue region are located by illuminating the tissue by measurement illumination. Stimulation in the functional tissue areas leads to a change in at least one optical property of the reflected measurement illumination compared to the original measurement illumination. The functional tissue areas are located based on the change in the at least one optical property of the reflected measurement illumination by determining the difference between a stimulation image of the tissue region obtained during the stimulation and a comparison image of the tissue region obtained without stimulation. The difference may be formed from at least one image recorded with the measurement illumination and at least one image recorded without the measurement illumination to bring about an increase in contrast. An obtained image may be corrected on the basis of the determined topography of the tissue region to bring about an increase in contrast.Type: GrantFiled: April 1, 2010Date of Patent: August 4, 2015Assignee: Carl Zeiss Meditec AGInventor: Martin Fanenbruck
