An assembly for advancing a colonoscope through the colon comprises a colonoscope 2 , a tube 4 and means for steering the tube 4 . The steering means comprises a series of wires 20 extending along the tube 4 to the tube distal end 5 to which the wires 20 are attached. By pulling on one or more wires 20 from a proximal end of the tube 4 , the tube distal end 4 may be steered by an operator as desired. The stiffness of the colonoscope 2 may be increased or decreased in use. |
