ABSTRACT:
An endoscopic instrument is disclosed which comprises a shank with a bendable region. The bendability is achieved by almost complete circumferential transverse recesses which form segments bendable to each other. To increase the robustness of the shank, the segments, at their free ends, are provided with guides which engage a neighbouring recess and are adapted to the contour of the shank. Furthermore in the lateral regions of the shank there are incorporated positive locking elements, which prevent the overloading of the shank on over-extension.
