Abstract

The utility model relates to a medical appliance. The utility model aims to solve the technical problem that a mammary duct radiography syringe needle that can safe and reliable accurately inject contrast medium is provided. The technical scheme adopted can be summarized as follows: a mammary duct radiography injection needle comprises a needle point (1), a needle stem (3) and a needle plug (2), wherein the needle point (1) is of a blunt-tip structure. The utility model has the advantages that: reasonable in design, low cost, the practicality is strong, easily realizes accurate puncture, and can inject the contrast medium closely, both can guarantee patient's interests, can improve the success rate and the reliability of radiography again. The utility model is suitable for a mammary gland radiography.

Description

The mammary ductography entry needle
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of mammary ductography entry needle.
Background technology
Nipple discharge are one of mastopathy common symptoms.Traditional main inspection diagnostic method is the mammary ductography method, during its concrete operations, inject contrast medium and take the photograph sheet in breast duct through the defeated newborn hole that is opened on nipple, whether form, trend, the distribution that can either show breast duct abnormal, also can determine whether in conduit or the outer lump of conduit with and the pathological change of adjacent tissue's structure.Due to the particularity of breast duct, if want, guarantee the success rate of radiography, in the radiography piercing process, must guarantee that operator have skilled operating technology and suitable lancet device.
At present, domestic situation of all-level hospitals completes mammary ductography with Peripheral vein infusion remaining needle overcoat or mammary ductography puncture needle usually.
Yet Peripheral vein infusion remaining needle overcoat, because the needle body is long, should not be sought defeated newborn hole, after entering breast duct, easily causes the damage of inwall; And connection tube is long causes operator to be difficult for grasping pressure, and when pressure was too small, contrast medium injected very few can't filling, when pressure was excessive, contrast medium injected too much, can enter acinus from the conduit tip, form tip catheter end lamellar increase in density in slight snow shadow on every side, the impact diagnosis.
And the mammary ductography puncture needle is that each is hospital-made, syringe needle is coarse, different in size, not only lack of standardization but also without unified standard, and sterilization and difficult quality guarantee.Due to connecting hose between puncture needle and syringe, be difficult for observing the breast duct endocrine and overflow situation.After using flexible pipe, operator are difficult to hold the contrast medium injection rate, and the resistance produced when can not the perception contrast medium saturated and make injection rate how easily be penetrated into the acinus of breast duct tip forms around tube wall flower sheet shadow in slight snow; And injection rate at least the subbranch conduit and last years of a century acinus fail to fill, show and to affect diagnosis effect not.And when puncture is random large, and depth of needle is estimating depth, the 1 grade of branch that so very easily punctures breast duct or thrust breast duct, and some conduit is developed and can not show the situation of diagnosing or treating the whole conduit of required observation.In addition, owing to can not holding separately pintle, can not lean on flexible pipe to support, easily violate aseptic operation, finally cause the radiography failure or seriously fail to pinpoint a disease in diagnosis.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of mammary ductography entry needle that can safe and reliable injection of contrast agent exactly.
The technical scheme that its technical problem that solves this utility model adopts is: the mammary ductography entry needle, comprise needle point, pin stalk and pintle, and needle point is blunt sharp structure.Blunt sharp structure i.e. tip has chamfering and not sharp-pointed structure.
Further, the pin stalk is 1:1.5-1:1.8 with the length ratio of pintle.
Preferably, the pin stalk is 1:1.5 with the Length Ratio of pintle.
Another program is: the mammary ductography entry needle, comprise needle point, pin stalk and pintle, and needle point is the tack structure.The tack structure i.e. the most advanced and sophisticated structure flushed.
Further, the pin stalk is 1:1.5-1:1.8 with the length ratio of pintle.
Preferably, the pin stalk is 1:1.5 with the Length Ratio of pintle.
The beneficial effects of the utility model are: reasonable in design, with low cost, practical, and be easy to realize accurate puncture, and can closely inject contrast medium, both can guarantee the patient's interests, can improve again success rate and the reliability of radiography.This utility model is applicable to the mammary gland radiography.
The accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment;
Wherein, 1 is needle point, and 2 is pintle, and 3 are the pin stalk, and b is the length of pin stalk, and d is the length of pintle.
The specific embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
As shown in Figure 1, mammary ductography entry needle of the present utility model, comprise needle point 1, pin stalk 3 and pintle 2, and needle point 1 is blunt sharp structure.
Another program of the present utility model is the mammary ductography entry needle, comprises needle point 1, pin stalk 3 and pintle 2, and needle point 1 is the tack structure.
Embodiment
In this example, needle point 1 is blunt sharp structure, smoothly without burr, avoids stabbing patient or its breast duct, safe and reliable.The needle point external diameter is 4.5mm, adapts with the aperture in the defeated newborn hole of nipple.Needle surface be shaped as ellipse or other shapes so that and the defeated newborn hole of nipple be complementary.
Choosing pin stalk 3 is 1:1.5 with the Length Ratio of pintle 2, and particularly, the length b of pin stalk 3 is 8mm, and the length d of pintle 2 is 12mm.Above-mentioned length meets the normal ducts degree of depth of China's human body, overcomes operator and is difficult for grasping the accuracy that piercing needle enters the degree of depth in breast duct, the probability of avoiding wearing out breast duct.In addition, also can puncture needle be made to different length according to the difference of human normal breast duct dissect physiology structure and use to adapt to different countries or zone, be 1:1.5-1:1.8 as pin stalk 3 with the length ratio of pintle 2.
Pintle 2 can directly connect conventional 2ml syringe, and do not utilize flexible pipe, can realize closely feeling the drag size in breast duct under needle point, the convenient operation human feeling enters the sense that falls through in breast duct, easily find suitable injection point, and be easy to observe the endocrine situation of overflowing of breast duct.In addition, operator use this device can closely inject contrast medium, the resistance produced when the perception contrast medium is saturated conscientiously is moderate to ensure the contrast medium injection rate, and overcome present many hospitals and reused the shortcoming that homemade polishing metal needle is difficult for sterilization, avoided occurring nosocomial infection.
