Publication number: 20050219376Abstract: A more effective larynx or vocal fold examination is facilitated when an image recording device, preferably a color image recording device comprising three modes is made available, a face-recording recording mode with a low recording frequency or image repetition frequency, respectively, but with a high resolution, a further face-recording recording mode with a higher image repetition frequency but with a lower resolution, and a one-dimensional, for example, row-recording mode also having a higher image repetition frequency. By the switchability of the image recording device between those modes the examining doctor is capable of first getting an overview by means of the slower image recording mode, wherein this may also be done in color, as due to the slower recording frequency this mode is not subject to the illumination problems like the high-speed camera.Type: ApplicationFiled: March 8, 2005Publication date: October 6, 2005Inventors: Thomas Wittenberg, Wolfgang Heppner, Stephan Gick, Hubert Voellinger, Ulrich Osterland, Thomas Belikan, Martin Dolt, Hans Bloss, Robert Couronne

Patent number: 6581117Abstract: The automatic control and administration of program-controlled endoscopic apparatuses allocated to an operation within an operating theater belonging to a clinic region and connected amongst one another by way of a CAN-bus using the standardized layer-seven CANopen protocol for communication among one another and a master computer, is modified so that with the same CAN-bus, a double ring structure, a ring-star structure and a ring-ring structure may be logically formed, permitting peer-to-peer communication of the apparatuses, with which the apparatuses have equality of access to each other and the master computer. The apparatuses, connected to one another via the CAN-bus, of all operating theaters of a clinic communicate with and are centrally controlled by the master computer. All apparatuses are capable of informing the master computer of the occurring process data or parameters. System operation is possible at the master computer as well as at the apparatuses themselves.Type: GrantFiled: February 2, 2000Date of Patent: June 17, 2003Assignee: Richard Wolf GmbHInventors: Wolfgang Klein, Martin Burger, Thomas Belikan

Patent number: 5113848Abstract: Apparatus for shock wave therapy comprises an electroacoustic therapeutic transducer for generating ultrasonic shock waves, which are transmitted by way of a coupling medium shock wave transmission section of the transducer, bounded by a membrane, to the body of a patient reclining on a therapy table. In the interest of hygiene the membrane is releasably attached by its marginal area to the therapy table, being thereby exchangeable so that a new membrane can be provided for each patient. The extraction of gas from the coupling medium following exchange of the membrane is provided for.Type: GrantFiled: September 5, 1990Date of Patent: May 19, 1992Assignee: Richard Wolf GmbHInventors: Werner Krauss, Helmut Wurster, Thomas Belikan

Patent number: 5095908Abstract: An apparatus is described for locating objects within the body, and particularly concretions situated in body cavities, in three dimensions and for destroying them. The point of departure for this is an electro-acoustic treatment transducer for generating shock waves to be emitted to focus on the object concerned and a B-scanner connected to the treatment transducer to act as a locating transducer for locating the object, the locating transducer being adjustable relative to the treatment transducer co-focally therewith. The design proposed envisages the locating transducer being integrated into the treatment transducer so that the sound fields of both transducers travel the same distances through the same media and it is thus the correct position of the focus relative to the concretion seen in the image which is in fact shown.Type: GrantFiled: August 13, 1990Date of Patent: March 17, 1992Assignee: Richard Wolf GmbHInventors: Thomas Belikan, Werner Knauss, Helmut Wurster
