Patent number: 7846090Abstract: The invention relates to an endoscope having a shaft in which at least one working channel is positioned and having on the distal end of the shaft an endoscope head, such that the part of the working channel contained in the endoscope head can be rotated with respect to the related working channel by a Bowden cable that is mounted on a control handle on the proximal end by a collet. To configure an endoscope in such a manner that it ensures simple construction as well as a constantly even tension of the Bowden cable, it is proposed with the invention that the depth of insertion of a cable cord of the Bowden cable into the collet can be limited by a pressure element acting on the cable cord and collet.Type: GrantFiled: August 31, 2006Date of Patent: December 7, 2010Assignee: Karl Storz GmbH & Co.
