摘要：
The invention relates to an endoscope with an outer tube (16) which is connected to an optical head (18), said optical head supporting an eyecup (24) or an adapter device for a camera system or an integrated miniature camera. An interior tube (34) is also provided in said outer tube, said inner tube extending into the optical head (18) where it is supported, and supporting the optical components. The outer (16) and inner (34) tubes are connected rigidly and tightly to each other at the distal end of the endoscope. The invention suggests that the exterior tube (16), the optical head (18) and the eyecup (24) or the adapter device or the integrated miniature camera are fitted together to form a first structural unit (12) which is rigid and forms a seal between these parts without being closed off to the outside, and that the interior tube (34) is fitted rigidly and tightly at its proximal end to a housing (36), said housing sealing the optical elements hermetically, to form a second structural unit (14).
摘要（中）：
内窥镜具有被连接到光学头（18）的外管（16），其携带用于照相机系统或者一个集成微型照相机的目镜（24）或一个适配器装置。 此外，在所述外管（16）布置并且延伸到延伸到所述光学头（18）和abgestütztes有内管（34）被提供，其携带的光学部件。 外管（16）和内管（34）在所述内窥镜的远侧端刚性地和密封地连接到彼此。 它建议，所述外管（16），光学头（18）和目镜（24）或所述适配器装置或集成微型摄像机，装配在一起，以牢固和这些部件之间的密封，但是向外未完成的第一单元（12），并且 在其近端中的光学部件（42）气密地密封外壳（36）的内管（34）刚性地且密封到第二组件（14）被组装。
