Publication number: 20130035687Abstract: An instrument suitable for minimal invasive surgery. The instrument can be introduced into a body, for example, through a trocar, and has two arms and a centrally guided knife for clamping vessels. The central guidance of the knife in at least one of the arms avoids disadvantages that could otherwise develop as a result of the off-center severing of coagulated tissue. Moreover, the clean central guidance of the knife results in lower wear on the knife. Thus, a better cut quality and a longer service life of the knife can be achieved.Type: ApplicationFiled: July 19, 2012Publication date: February 7, 2013Inventors: Juergen Hiller, Thomas Baur, Ralf Kuehner, Viktoria Rydzewski

Publication number: 20120232540Abstract: A surgical instrument that comprises at least one microcontroller arranged in the handle of the instrument and that communicates with the surgical apparatus—without the interposition of a radio link via the cable that already exists between the surgical apparatus and the surgical instrument. Safe data transmission is ensured not only in the high-interference environment of an active RF surgical apparatus, but also in water jet, argon plasma and cryosurgical apparatuses, endoscopes or the like. A differential transmission technique is selected, wherein one or more conductor pairs (insulated conductors) are utilized, one of the conductors of said conductor pairs transmitting the signal and the other transmitting the inverted signal. By subtracting the two signals, the actual data signal is yielded on the receiver side. If feedback interferences from the environment act on the data transmission link, the subtractions performed on the respective receivers cancels out the interferences.Type: ApplicationFiled: February 21, 2012Publication date: September 13, 2012Inventors: Thomas Baur, Marc Kegreiss, Peter Selig

Publication number: 20120006415Abstract: The invention provides a rinsing device, in particular for endoscopy, comprising an electrically driven pump, in particular a peristaltic roller pump, as well as a method of operating such a device. A control device is provided to detect and/or adjust a flow rate. In order to avoid an excessively high pressure in case of an unintended stenosis, e.g. kinking of the supply tube, or also intended stenoses, e.g. insertion of a narrow rinsing probe, a current-measuring device is provided to detect a current being received by the pump. The control device is adapted such that when the flow rate exceeds a prespecified limiting value and at the same time the current exceeds a first predetermined current value, the flow rate is reduced to a safe flow-rate value.Type: ApplicationFiled: September 20, 2011Publication date: January 12, 2012Inventor: Thomas Baur

Patent number: 7630022Abstract: A birefringent optical filter and associated method are described which demonstrate improved performance for both fixed and tunable filter configurations. One exemplary embodiment involves an initial filter configuration, having an output polarizer, that exhibits an initial spectral filter response having an undesired transmission feature and a desired transmission feature. An additional polarizer follows the output polarizer and an adjustable retarder is disposed directly between the output polarizer and the additional polarizer to produce an overall spectral filter response that eliminates the undesired transmission feature, while passing the desired transmission feature. Another exemplary embodiment uses at least one reflective polarizer for passing light along the filter optical path, which light is characterized by a selected polarization, and for reflecting a rejected light that is characterized by a different polarization such that the rejected light is directed out of the optical path.Type: GrantFiled: September 20, 2006Date of Patent: December 8, 2009Inventors: Thomas Baur, Joel R.
