Abstract
A control mechanism for an endoscope (1) comprising a Bowden cable. the Bowden cable has an outer guide tube (9) having a first length between a proximal end and a distal end of said outer guide tube (9) and an inner pull-wire (15) having a second length between a proximal end and a distal end of said inner pull-wire (15). The second length is longer than the first length. The outer guide tube (9) comprises a first guide tube section (9′) and a second guide tube section, where said first guide tube section (9′) has plastic and elastic properties, which are different from the plastic and elastic properties of said second guide tube section (9″).
