Abstract

The canal (1) is made of spirally wound one or more strips(2). The free, unconnected to the canal (1) sectors of strips (2)pass into the interior of the canal (1) and are freely positionedalong its entire length in guiding canals (5) of endoscope (3) orin the external revolving part of endoscope (3) when the interiorpart to which its head is fixed does not revolve. The extension orshortening of canal (1) and the change of its form in itsextension is made by matching linear motion in the desireddirection and revolving of endoscope (3) or only of its revolvingouter part in the direction of winding of the spiral (2) andextension in the direction of unwinding of the spiral when thecanal (1) is being shortened.7 claims, 5 figures
