  • 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.

  • Device for the picture-providing diagnosis of tissue using one of at least two diagnosis modes
    Patent number: 8019405
    Abstract: A device for picture-providing diagnosis of tissue is selectively operated in a picture-providing white light diagnosis mode and a picture providing auto-fluorescence mode. A color camera having red, green, and blue sensors provides a monitor which picture signals. A light source emits fluorescence excitation light and additionally emits so much red light that the red light remitted by the tissue dominates the red fluorescence light in the picture providing auto-fluorescence mode. The signal from the red sensor of the camera is damped so that normal time appears green and pre-malignant and early malignant tissue appears red.
