A catheter desobstruction system for desobstructing a catheter, with a catheter desobstruction apparatus and a catheter desobstruction drive, wherein:the proximal end of the flexible catheter cleaning cable is introduced into a lumen of the catheter；the proximal end of the flexible catheter cleaning cable in moved into the proximal direction by the actor of the catheter desobstruction drive；if a force detected by the force sensor of the catheter desobstruction drive exceeds a predetermined threshold, the flexible catheter cleaning cable is moved in the distal direction for a first predetermined distance by the actor；when the flexible catheter cleaning cable has been moved the first predetermined distance in the distal direction, the proximal end of the flexible catheter cleaning cable is rotated by the motor of the catheter desobstruction drive and the flexible catheter cleaning cable is moved in the proximal direction by the actor.
