An actuating device for catheters comprising at least one first part (T) and one second part (G), which are able to perform a travel (R) of relative movement, comprises: a slide (2) which can be connected to one (G) between the first part (T) and the second part (G) of the catheter; a slider (3), which can be actuated for moving the slide (2) and performing the aforesaid travel of relative movement; and a speed-change mechanism (7, 9, 12), which is set between the slider (3) and the slide (2) and is able to perform transmission of the movement between the slider (3) and the slide (2). <??>Preferentially, the speed-change mechanism (7, 9, 12) affords at least two different drive ratios in successive parts of the aforesaid travel of relative movement. <IMAGE> |
