The invention discloses a magnetic catheter with trawl wire capture capability. A magnetic part is arranged on the magnetic catheter close to the head of the magnetic catheter, and a plurality of barbs are arranged on the outer surface of the magnetic part, and one end of each barb is connected with the magnetic catheter, while the other end of each barb is arranged toward the tail part of the magnetic catheter. When the magnetic catheter provided by the invention is used, the magnetic catheter is fed into the anterior urethra of a patient by adopting conventional catheter retaining operation; and after a trawl which can be adsorbed by a magnet is adsorbed by the magnetic part, the magnetic catheter is pulled outward, and the trawl is hooked by the barbs arranged on the outer surface of the magnetic part to prevent the trawl from slipping away from the magnetic catheter, so that the success rate of extracting the trawl out of the urethral orifice is increased, and the aim of quickly pulling out a catheter stent tube which is implanted in a patient body and provided with a trawl can be achieved.
