The invention relates to a flexible endoscope or an endoscope attachment and to a method for producing same. Until now only glass fiber endoscopes have existed for examining very small channels that are highly sensitive to mechanical or sensory stimuli in particular in medicine, such as the tuba auditiva for example. Said glass fiber endoscopes are flexible but still too rigid to be painlessly inserted into the middle ear for example. Thus, said glass fiber endoscopes carry the risk of hemorrhages and mucous membrane injuries which can lead inter alia to the formation of scars with subsequent chronic middle ear inflammation. A soft, highly flexible endoscope made of silicone would solve said problems and render operations such as those that are currently carried out for diagnostic purposes unnecessary in many cases. The flexibility of the endoscope is achieved by using silicone as the imaging material. The light guides are produced from highly flexible soft silicone that is highly transparent in the light spectrum required for use by applying, pressing, and curing silicones that are initially liquid in layers. Each layer, which has a thickness of only a few micrometers, consists of rib waveguides which have a width and height of a few micrometers and which are made of a highly refractive silicone layer (core) surrounded by a weakly refractive silicone layer (casing), and each strip waveguide of the highly refractive structured layer generates an image pixel. A soft silicone lens (2) which can be produced by curing a drop of silicone on an anti-adhesive coated substrate focuses the image signal onto the waveguide matrix (1). The waveguide matrix (1) and the lens (2) are encased with an optically highly transparent, weakly refractive casing (3). An optically insulating soft material (4), for example silicone, is subsequently applied by spraying, brushing, or the like and cured. Further functions can be realized in said optically insulating layer (4), for example a mechanical control that is realized by thin metal bands, by means of which the distal end of the endoscope can be bent, or channels for feeding and suctioning liquids. Finally, the endoscope is coated with an optically conductive casing which is used to supply light for lighting the object to be observed and which consists of an optically transparent silicone layer or a layer system of optically transparent, weakly and highly refractive silicone layers, wherein a highly refractive shaft 6 can be found between two weakly refractive shafts (5) and (7) so that the light is guided in the highly refractive region (6). The silicone endoscope is suitable for examining very small channels that are highly sensitive to mechanical or sensory stimuli in particular in medicine on the basis of the material properties of the silicone endoscope.
