Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of angiography catheter.
Background technique
Infertility has become a kind of the third-largest disease for being only second to tumour and cardiovascular disease, and China's infertility incidence is being educated
In increased trend year by year in age Mr. and Mrs, wherein Infertility caused by fallopian tube obstruction accounts for the 1/3 of female acyesis ratio, also there is document report
Up to 40~60%, become an important factor for influencing stable family and quality of life.The diagnostic method of tubal occlusion mainly has
Uterotubal insufflation, hydrotubation, sonosalpingography art, hysterosalpingography art, selective fallopian tubal
Radiography, wherein selective salpingography is considered as most accurate inspection method.Through x-ray is to pass through with Salpingography
Conduit injects contrast agent to uterine cavity and fallopian tubal, using x-ray diagnostic equipment row X-ray examination and piece is taken the photograph, according to contrast agent in fallopian tubal
And Intrapelvic development situation understands whether unobstructed fallopian tubal, obstructive position and a kind of detection method of uterine cavity shape.
Conduit is inserted into cervical orifice from human vagina in Salpingography, so oviduct-radiography catheter is necessary
It is linear.Since fallopian tubal is the palace angle for being located at uterus, and existing oviduct-radiography catheter angiography tube head end is cecum,
Only side opening, and sacculus be it is eccentric asymmetric, easily there is false positive in when radiography, and is easy insertion due to lacking scale marker
It is too deep, furthermore the lubricity of conduit is generally bad, easily causes pain uncomfortable to patient, since material limits so that conduit development effect
Fruit is bad, can not promptly and accurately judge the position of conduit and then be difficult to be directed at palace angle.Therefore existing oviduct-radiography catheter only has
It can be only achieved ideal surgical effect by the patient that clinical experience is abundant and feel is splendid.
Therefore, the prior art is to be improved and improves.
