The needle localization of non palpable breast lesions is intended to enable the physician to localize these lesions in order to proceed with their screening and possibly the next surgery. The device is used with an invasive method which provides inside the needle a hooked wire that, when you reach the breast lesion, is pushed into the lesion. The wire, which has a special bend in the extreme (single or double), you still breast parenchyma and allows the surgeon, in a second phase, to easily identify the location, minimizing the amount of parenchyma excised injured.
