Multiple positioning drainage device in breast ducts

Abstract

The invention aims to provide a multiple positioning drainage device in breast ducts. The device is used for treating breast ducts and diseases related to the breast ducts. The device is characterizedin that: the drainage device consists of a guide wire and a sleeve sleeving the guide wire, wherein the sleeve is a transparent tube, and the front end of the sleeve is provided with a metal coating.The metal coating at front end can be imaged under radiation, so that the position and direction of the surgical incision can be accurately set before surgery. The head of the sleeve can also be fixedly provided with an inflatable balloon so as to accurately judge the position of the main breast duct in which the lesion is located.

Description

Technical field [0001] The invention relates to the field of medical equipment, and in particular provides a multiple positioning drainage device in a milk duct. Background technique [0002] Intraductal papilloma is the most common cause of pathological nipple discharge. Breast endoscopy is the most accurate method to find intraductal papilloma. The more commonly recognized surgical procedure is to perform the diseased main duct and its associated areola under the areola incision. Complete resection of gland lobes. The surgical incision is generally determined by the shape of the diseased milk duct found during ductoscopy. The method of finding the main milk duct where the lesion is located during the operation is generally to insert a flat needle into the main milk duct, then inject blue dye through the flat needle, and judge the direction of the main milk duct of the disease by touching the flat needle in the milk duct. The boundaries of breast tissue to determine the scope ...

AI Technical Summary

Problems solved by technology

First of all, for the milk duct near the center of the nipple, it is difficult to determine the direction of the diseased milk duct and the position of the areola incision by relying on the position of the light spot during ductoscopy

If the direction of the areola incision is wrong, a lot of dissociation and exposure are required to find the main milk duct where the lesion is located and the breast lobe to which the milk duct belongs, which not only increases the difficulty of the operation and the amount of anesthesia, but also increases the damage Peripheral Duct Chances

Secondly, due to the limited length of the blunt needle, it is more difficult to determine the direction of the main milk duct by palpation; as the operation time prolongs, the blue dye continues to extravasate and diffuse around the milk duct, resulting in an unstable blue dyeing range, which is common. Too large; in the process of separating and looking for the main milk duct of the lesion, the main milk duct or the branch milk duct connected with it will often be broken, resulting in the overflow of the dye, resulting in the inability to judge the extent of the lesion, etc.

The above shortcomings will reduce the accuracy of the operation, significantly increase the scope of surgical resection, and seriously damage the milk duct around the main milk duct of the lesion, resulting in the loss of breastfeeding function of this side of the breast; making the breast tissue at the far end of the lesion duct blue The scope of dyeing is too large, and the surrounding normal breast tissue is removed too much, resulting in breast deformation and seriously affecting the appearance

[0004] Indwelling and positioning crochet needles at the lesion in the milk duct through the opening of the milk duct under ductoscopy is a relatively accurate method for locating the position of the lesion in recent years. Detachment and displacement-leading to the disadvantages such as the inability to judge the location of the lesion

[0005] In addition, when performing mammary ductoscopy on bloody nipple discharge, sometimes there will be a negative test result, that is, there is no bloody fluid in the milk duct examined by mammary ductoscopy. The root cause is that the milk duct divides into two branches quickly after the nipple opening , the normal branch milk ducts are entered during ductoscopy, but the branch milk ducts where the lesion is located are missed, which leads to the inconsistency between the test results and the clinical symptoms
