Abstract

A cannula (1) for movement along determined trajectory, consisting of numerous longitudinal bands (2), connected with cross links, which allow their sliding in respect to each other. The movement of the cannula (1) is effected by abrupt strokes longitudinally upon one separate band, whereat it slides at a definite distance in respect to its neighbouring bands, whereas the remaining bands remain linked and static in respect to each other, followed by the same strokes, consecutively upon each of the remaining bands and repeated repetition of the cycle until the movement at the desired distance is achieved. The immobility of the numerous bands with the exception of one, ensures the mechanical memory of the cannula for its location in the different sections of space and its movement along a determined trajectory.
