Patent number: 10624540Abstract: An operating microscope including an optical unit for forming an image of an object plane in oculars of the microscope, an optoelectronic image receiver coupled to the microscope and optics to form images, of objects placed in a region between a front objective of the microscope and an object plane of the microscope, on the optoelectronic image receiver. The microscope has a magnification factor of the optics to form images, and a system to detect optical markings forming a markings pattern placed on a surgical instrument or an object placed in the region between the front objective of the microscope and the object plane of the microscope. The system calculates a geometrical position and orientation of the markings pattern in relation to the optoelectronic image receiver, relative to the microscope.Type: GrantFiled: March 2, 2015Date of Patent: April 21, 2020Assignee: Moeller-Wedel GmbHInventors: Martin Schmidt, Jochen Koetke, Peter Schalt, Stefan Oelkers, Rolf-Rainer Grigat, Thomas Hoell

Patent number: 7912532Abstract: The invention relates to a method for positional optimization in navigation, in particular neural navigation in surgery with an operation microscope and at least one optoelectronic image detector which may be connected to the microscope and also a computer system. The data obtained from the at least one image detector which lie in the microscope field-of-view for the operator, contain information on the position of an operation instrument, in particular the instrument tip. The actual position of the instrument in the x- and y-direction as well as in the z-direction of a three-dimensional coordinate system is continuously or intermittently determined from the relevant positional data. A separation determination is carried out for the positional determination in the z-direction by means of depth of focus evaluation and/or stereoscopic image analysis.Type: GrantFiled: June 11, 2003Date of Patent: March 22, 2011Assignee: Moeller-Wedel GmbHInventors: Martin Schmidt, Jochen Koetke, Peter Schalt, Stefan Oelckers, Rolf-Rainer Grigat, Lars Eckert, Thomas Hoell

Patent number: 7505201Abstract: The invention relates to a method for optimized setting of light power at the object plane in the case of reflected light microscopes, surgical microscopes in particular. In accordance with the invention, a check is performed as to whether or to what extent thermal danger or damage to the illuminated sections is relevant in order to regulate, in particular limit, the light output of a light source upon a threshold being reached.Type: GrantFiled: October 14, 2005Date of Patent: March 17, 2009Assignee: Möller-Wedel GmbHInventors: Stefan Oelckers, Peter Schalt
