This specification provides a system and device for locating intraductal lesions of the breast based on PROLENE sutures, relating to the field of intelligent medicine. It includes: a ductoscope insertion module configured to insert a ductoscope with a cannula into the breast duct and reach the lesion area; a suture insertion module configured to pass one end of the suture through a side hole in the cannula to reach the lesion area; a suture insertion distance marking module configured to identify a first position of the exposed suture segment outside the cannula and measure the distance from the distance mark to the nipple; a ductoscope withdrawal module configured to withdraw the ductoscope while observing the ductoscope's field of view, positioning the suture around the lesion area; and a distance correction module configured to, after withdrawing the ductoscope, identify the current position of the distance mark on the suture, determine whether the current position matches the first position, and if not, adjust the distance mark to the first position. Using sutures does not damage the tumor or surrounding tissue, reduces the risk of missed diagnoses, and causes no discomfort during the procedure.
