A steerable tube for endoscopic applications includes a first, a second and a third part. The first part includes a first movable portion and the third part includes a second movable portion. The steerable tube includes longitudinal elements that are constructed and arranged such that a change in orientation of the first movable portion of the first part with respect to the second part results in a change in orientation of the second movable portion of the third part with respect to the second part. The longitudinal elements are constructed and arranged such that they are twisted and/or that they are twistable. An endoscopic instrument and an endoscope including the steerable tube, and an assembly including an endoscopic instrument and the endoscope are also described.
