Description

A kind of mammary ductography pin

Technical field

This utility model relates to a kind of mammary ductography pin, belongs to medical machinery, particularly relates to a kind of apparatus being exclusively used in tumor auxiliary diagnosis and treatment in female mammary gland conduit.

Background technology

The sickness rate of breast carcinoma is all in rising trend in the whole world, and breast carcinoma has become and has a strong impact on one of even life-threatening most common cancer of women's physical and mental health.The early diagnosis of breast carcinoma ,, correct in time treatment, can not only cure rate be improved, extend life cycle, and to maintaining the formal beauty of female patient, improve patient's self-confidence, improving the quality of living, is all very significant.

Diagnostic method many dependence B ultrasonic of current Mammary intraductal tumor, breast duct scope, nipple discharge exfoliative cytology check and mammary ductography.Time less for tumor body or when nipple rear, many not easily discovery of ultrasonic examination and cause failing to pinpoint a disease in diagnosis; Though breast duct endoscopy can be looked at straight and check, to being positioned at main pipe far-end, tumor body compared with fine duct, cannot go deep into due to scope therefore being difficult to diagnosis; Though the inspection of nipple exfoliative cytology is simple to operate, have certain diagnostic value, Chang Yinwei collects oncocyte and occurs false negative diagnoses.

Mammary ductography inspection can overcome the shortcoming of above-mentioned inspection, a kind of can clarifying a diagnosis and safe and reliable inspection method, this inspection can show mammary duct ectasia, tortuous, filling defect, pressurized displacement, and when finding the irregular infiltration of tube wall, stiff and narrow change, many considerations intraductal carcinoma may.But, because at present mammary ductography utensil used kind is less, after how transforming syringe needle by 5ml syringe, carry out inspections use, very easily cause via.Meanwhile, because syringe needle caliber does not conform to latex dust caliber, during bolus administration of contrast agent, because overpressure increases, often occur that contrast agent is excessive, impact diagnosis.Have at present and use flexible pipe syringe needle for contrast examination, but interior metal nook closing member need be managed when entering latex dust guide, and flexible pipe is opened on side, make to inject during bolus administration of contrast agent pressure large, and contrast agent under stress can to the flowing of far away, near two ends, except contrast agent is easily excessive, also make contrast agent not easily distally narrower latex dust motion.

Summary of the invention

This utility model object is, a kind of mammary ductography pin being exclusively used in Mammary intraductal tumor contrast examination and diagnosis is provided, this mammary ductography pin is rabbeted mouth, latex dust pin, scale, syringe needle, cork and injection orifice formed by handle, tongue and groove, syringe, described mammary ductography pin coordinates the required syringe connected to use, be conducive to accurately to diseased region bolus administration of contrast agent and dyestuff, the scale of the display depth of needle that latex dust wire surface is arranged is conducive to observing and controlling depth of needle; The blunt syringe needle of circle is easy to insert newborn hole, and can avoid damage latex dust and perienchyma and formation via; Syringe needle has good suppleness and compliance, not frangibility, is conducive to the hand-manipulating of needle in tortuous latex dust.Mammary ductography pin both can be in conduit tumor imaging diagnosis bolus administration of contrast agent used, also can be excision pathological changes conduit time inject dyestuff location focus used, medicine injection in latex dust inflammatory diseases can also be used for and carry out anti-inflammatory treatment.This mammary ductography needle construction compact, without the need to by metal rack inserting needle, avoids Accessory injury, eliminates that pull out after metal rack just can bolus administration of contrast agent link, and it is very convenient to operate.Through Clinical practice checking, it has the advantages such as easy to operate, cheap, safe and reliable and contrasting effects is good.

Mammary ductography pin described in the utility model, this mammary ductography pin is rabbeted mouth, latex dust pin, scale, syringe needle, cork and injection orifice formed by handle, tongue and groove, syringe, one end of latex dust pin (5) is connected with handle (1) one end being provided with tongue and groove (2), have at the other end of handle (1) and rabbet mouth (3) with syringe, its port uses cork (4) sealing; Cavity in latex dust pin (5) and syringe are rabbeted mouth (9) and are communicated, and are provided with the scale (6) of display depth of needle on the surface of latex dust pin (5), and latex dust pin (5) head is round blunt syringe needle (7).

Accompanying drawing illustrates:

Fig. 1 is overall structure schematic diagram of the present utility model;

Fig. 2 is profile of the present utility model.

Legend: 1, hands handle; 2, tongue and groove; 3, syringe interlocking mouth; 4, cork; 5 latex dust pins; 6, scale; 7, syringe needle; 8, injection orifice.

Detailed description of the invention

Further describe below in conjunction with accompanying drawing, and provide specific embodiment:

As accompanying drawing 1,2, mammary ductography pin of the present utility model is the structure be combined into one by handle 1 and latex dust pin 5 two parts, rabbeted mouth, latex dust pin, scale, syringe needle, cork and injection orifice formed by handle, tongue and groove, syringe, one end of latex dust pin 5 is connected with handle 1 one end being provided with tongue and groove 2, have at the other end of handle 1 and rabbet mouth 3 with syringe, its port uses cork 4 to seal; Cavity in latex dust pin 5 and syringe are rabbeted mouth 9 and are communicated, the scale 6 of display depth of needle is provided with on the surface of latex dust pin 5, latex dust pin 5 head is round blunt syringe needle 7, for being conducive to holding and the operation of rolling inserting needle, make the material of handle 1 and need that there is certain hardness and rigidity, can select third rare fine-the nontoxic rigid polymeric material such as butadiene-styrene copolymer; For meeting latex dust pin 5 pairs of suppleness and compliance and being convenient to the requirement observed, can select as this kind ofly in polyfluorinated ethylene propylene nontoxic to there is again good flexible soft transparent polymeric material, consider that above-mentioned two parts have different requirements to material, one-shot forming technique can be utilized to make respectively, then heat seal or technique for sticking is utilized to connect as one, cork 4 uses common nontoxic flexible material to make, contaminated for preventing syringe from rabbeting mouth 3;

In use, conventional method is adopted to use povidone iodine to nipple, mammary areola district carries out disinfection, newborn bore expansion device is utilized to expand discharge breast hole, hand-held breast duct pin handle 1, rolling inserting needle is carried out in the newborn hole that syringe needle 7 perpendicular alignmnet has been expanded, when syringe needle 7 enters newborn 2-3cm place, hole, fixing mammary ductography pin, open the cork 4 of afterbody, appear syringe interlocking mouth 3, the ready syringe mastoidea that contrast agent or dyestuff are housed is inserted in breast duct pin by syringe interlocking mouth 3, contrast agent or dyestuff are slowly injected in discharge latex dust by the injection orifice 8 in syringe needle 7, namely sheet or guided surgery excision pathological changes latex dust is taken the photograph by x-ray radiography.
