    • An endoscope is disclosed, in particular an insertion aid for an endoscope (3) which can be arranged at the distal end of the endoscope tube (3a) and works as a tubular structure which is turned inside out (23). The insertion aid has an element (22) for receiving the tubular structure (23) in an initial, folded state, the front end of the tubular structure being joined to the receiving element. The controlable flexible distal end of the endoscope, can be bent even when the endoscope tube (3a) is sharply bent owing to the fact that the traction cables (40, 41) are arranged each in a small, longitudinally extensible tube (36, 37) and when one traction cable (40, 41) of a pair of traction cables is extended, a vacuum is pneumatically or hydraulically applied to the associated small tube and overpressure is applied to the small tube of the other traction cable (40, 41) of the pair of traction cables.
    • 本发明涉及内窥镜,特别是插入辅助内窥镜(3),其(3A)是在内窥镜管的远端,并且可以根据向上ausstülpenden软管形成的原理来布置(23)进行操作。 插入辅助具有用于形成软管(23)在折叠的初始状态,其中,所述软管形成的前端与接收元件连接的保持元件(22)。 内窥镜的控制可弯曲的远端的弯曲,即使在内窥镜管(3A)的一个大的弯曲,从而允许在长度管(36,37)的列车(40,41)的每个中的伸缩性被布置,并且 相关联的管Zugpaares气动或液压与真空系(40,41)的Zugpaares的提取和其他列车(40,41)的管期间在由过量的压力作用。
