  • Method for manufacturing a bendable tube
    Patent number: 8327518
    Abstract: With a method for manufacturing a bendable tube, which is preferably envisaged for an endoscopic instrument, first a tube is separated into several tube sections in a manner such that adjacent tube sections engage into one another with a positive fit in the axis direction of the tube. After the separation of the tube into several tube sections, one envisages peripherally arranging means for providing a positive fit transversely to the axis direction of the tube, on the regions of the tube sections, which are situated in engagement with one another.

  • ENDOSCOPE WITH VARIABLE DIRECTION OF VIEW
    Publication number: 20120271112
    Abstract: An endoscope with a variable direction of view is provided, which includes an endoscope shaft and imaging optics arranged inside the endoscope shaft. These image an object located before the distal end of the endoscope and produce an image of the object in the proximal area of the endoscope in which a field stop is arranged. The produced image is larger than the field stop. In the proximal area of the endoscope an image module is arranged with which the relative position between the produced image and the field stop can be changed for changing the section of the produced image visible after the field stop in order to change the direction of view of the endoscope.

  • ENDOSCOPE WITH VARIABLE DIRECTION OF VIEW
    Publication number: 20120265017
    Abstract: An endoscope includes a handle and a shaft connected thereto. Imaging optics are arranged in the shaft that image an object located in the direction of view of the imaging optics in front of the shaft as an image and which to set the desired direction of view. The imaging optics comprise a swivellably housed deflecting unit positioned at the distal end of the shaft facing away from the handle. The possible swivel range of the imaging optics has a first and a second limit, as well as an actuating element, which is attached to the handle and which is mechanically connected to the deflecting unit. Thereby the swivel position of the deflecting unit within the swivel range can be changed in order to set a desired direction of view. A first mechanical stop is provided against which the deflecting unit lies when the first limit is reached.
