Abstract
The present invention is a remote control catheter designed principally for cardio-vascular surgery, characterized by the fact that it permits its user to directly control, starting from the handle of the instrument, the orientation of its head by means of a control wire (31) attached to the extremity of the head of the catheter while at the same time being eccentric with respect to the axis of this latter on the one hand, and to the extremity of the traction pinion (34) placed at the interior of the handle on the other hand, this latter being displaceable in the direction of its axis and consequently to pull or release the control wire (31) while the user exerts a rotary movement to the control collar (37) driving through its interior teeth the intermediate pinion (36) this latter meshing at its exterior in the tooth (35) of the traction pinion (34) which similarly has a male screw threading (38) cooperating with a female screw threading (39) fixed with respect to the handle.
