A nipple traction device for curing nipple retraction comprises a cup-shaped plastic sleeve, steel wires and a lifting nut, and is characterized in that the upper part of the cup-shaped plastic sleeve adopts a hollow cylinder, positioning grooves are formed in the lengthwise direction of the cylinder body in four positions of rpendicular diameters of the cylinder, threads are formed outside the cylinder, the lifting nut is connected with the hollow cylinder through internal thread, and the steel wires are arranged on the lifting nut and extend to the center of circle of the hollow cylinder through the positioning grooves. When in use, the nipple is sleeved into the cup-shaped plastic sleeve on a rectifier and pulled out with moderate suction; the steel wires are pierced into the nipple above the lifting nut to be fixed through the positioning grooves on the cup-shaped plastic sleeve; the lifting nut is rotated to adjust the height. The utility model is remarkably in solving the defects of the prior art that scars are left after serious nipple retraction operation to damage the attractive appearance of the breasts, lactiferous ducts are easily damaged to influence breast-feeding, and the relapse into nipple retraction, and provides a compromise minimally invasive medical appliance between medical appliances for the negative pressure noninvasive nipple retraction operation and the traditional serious nipple retraction curing operation.
