Description

Milk tube support

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a breast duct support.

Background

Nipple discharge, breast pain and breast lumps are the most common three chief complaints seen in breast surgery outpatients. Nipple discharge patients can account for, on average, from 1/10 to 1/20 of breast surgery outpatients. The incidence of nipple discharge diseases tends to increase year by year. When a patient has nipple discharge, there is a chance of breast malignancy about 5% to 8%, and the other common causes may be intraductal papilloma, hyperplasia of the ductal epithelium of the breast (including atypical hyperplasia), dilation of the breast duct or elevated prolactin. At present, the intraductal lesions (intraductal papillary tumor, papillary tumor with atypical hyperplasia, intraductal papillary carcinoma and papillary carcinoma with infiltration) which are clinically characterized by nipple discharge are collectively called intraductal papillary tumor, and once diagnosed, the lesions need to be treated by operation. The existing diagnosis method for nipple discharge patients mainly comprises the steps of galactoscopy, cast-off cytology examination, galactography and the like. Although the literature reports that about 60% of patients with nipple discharge have positive findings by performing a mammoscope examination, it is difficult to observe or acquire pathological data of malignant tumors originating in the distal duct (TDLU) of the mammary gland; moreover, as an invasive operation, the ductoscopy may cause damage to the breast duct, thereby promoting the implantation and metastasis of tumors or causing the nipple discharge to stop after the breast duct is adhered, and bringing difficulty to find the discharge breast hole and inject the beauty blue to determine the surgical resection range in the subsequent surgical treatment. In addition, clinical application value of the mastoscope is not high and the cost is high, and a lens light source is easy to damage and is difficult to popularize in primary hospitals. The detection of the exfoliated cancer cells in the liquid discharge smear is the most direct qualitative diagnosis for the reason of the liquid discharge of the nipple, but the positive rate of the exfoliated cancer cells detected by the liquid discharge smear of the nipple in clinical practice is not high, and a certain false positive rate exists. And the basic level hospital is limited in pathological diagnosis level, and the cytological examination items of nipple discharge are less developed. The breast duct radiography is the most valuable clinical positioning diagnosis method of nipple discharge diseases at present, and is helpful for positioning of surgical incision and determining of excision range. According to the examination method, the molybdenum target slice of the breast is shot after the developer is injected from the galactophore, so that the form of the galactophore duct can be displayed, the position of the lesion in the breast and the possible range of the glandular lobe of the whole lesion duct can be determined, and some typical radiography symptoms can provide certain reference for judging the quality and the malignancy of the galactophore lesion. And at present, many primary hospitals are equipped with molybdenum target photographic equipment, so that the breast duct radiography is the first inspection means for the nipple discharge diseases at present in China. However, for physicians with poor experience in mammography or patients with small nipples and narrow ducts, sometimes the use of a conventional needle may inadvertently penetrate a "false passage", resulting in failed radiography and unnecessary iatrogenic injuries.

SUMMERY OF THE UTILITY MODEL

In view of the above problems in the prior art, the present invention provides a breast duct support to solve the above problems.

A breast duct stent comprises a probe and a stent body. The probe comprises a probe head and a base connected with one end of the probe head; the other end of the probe is a hemisphere which can avoid damaging the breast duct or forming a false passage when being inserted into the breast duct; the bracket body comprises a bracket tube communicated with the middle part and a baffle plate connected with one end of the bracket tube; the probe penetrates through the inner cavity of the bracket tube, and the base is abutted to the baffle.

Furthermore, the probe and the bracket body are made of non-metal materials, and the bracket body has certain hardness. This avoids irritation or damage to the milk ducts. Such as silica gel, polylactic acid, polyurethane, and the like.

Further, the length of the probe is set to be 13-15 mm.

Further, the length of the support tube is set to be 6-7 mm. The length of the main catheter of a common breast duct is 7-8 mm, and the length of the bracket tube is set to be slightly shorter than that of the main catheter, so that the secondary catheter can be prevented from being injured.

Furthermore, the diameter of the support tube is 0.5-0.7 mm. The diameter of the breast hole and the breast duct is 0.5-2.3 mm. Such an arrangement may facilitate insertion of the stent tube.

Further, the probe is arranged as a through pipe. The disposable injector can be inserted into the base after the through pipe, which is convenient for the operation of the breast duct bracket and can also directly inject the developer into the breast duct.

Further, the baffle is provided in a color different from that of the nipple. Such as red, yellow, etc. Therefore, the position of the breast hole can be marked, and a developer is injected to position a lesion breast duct system conveniently during operation.

The working principle of the utility model is as follows: when the breast duct is intubated, the probe is firstly inserted into the bracket body; then inserting the probe into the breast duct through the breast hole, stopping inserting the probe when one end of the stent tube approaches the breast hole, and pushing the stent tube into the breast duct; and finally, withdrawing the probe. The contrast can be performed by injecting or introducing a contrast agent into the stent tube.

The utility model has the beneficial effects that:

(1) the utility model solves the problem that the galactophore hole often stops overflowing after the galactoscopy brings difficulty to the positioning in the subsequent operation treatment, and the galactophore hole can be marked after being inserted into the bracket body, and the injection of methylene blue is convenient to position a diseased galactophore system in the operation.

(2) The probe end is set to be a hemisphere, which is beneficial to the detection of the position of a true spilled liquid breast hole before the mammary duct radiography, and the iatrogenic injuries such as the puncture of a radiography needle into a false passage can be effectively avoided after the probe is placed into the bracket body.

(3) For a patient with porous overflow liquid, a plurality of stent bodies can be placed in advance and then contrast agents are injected simultaneously, so that the problem of uneven development caused by delay of injection time of the contrast agents of the patient with porous overflow liquid at present is solved.
