Hydrotubation radiography re-hydrotubation device

Abstract

The invention relates to a hydrotubation radiography re-hydrotubation device. The hydrotubation radiography re-hydrotubation device comprises a guide wire, a microcatheter, an inner sleeve and an outer sleeve which are sequentially connected from inside to outside in a sleeving manner. The body of the guide wire is a metal wire, the surface of the body of the guide wire is wrapped by high-polymer materials and are uniformly coated by smooth medical hydrophilic coating. The body of the microcatheter is made of high polymer materials, the front end of the microcatheter is provided with a conical head made of flexible materials, and the rear end of the microcatheter is provided with a joint which enables the guide wire to penetrate to be connected with an injector. The inner sleeve is a metal catheter, and the rear end of the inner sleeve is communicated with a guide part convenient for the microcatheter to penetrate. The outer sleeve is made of high polymer materials, and the head of the outer sleeve is provided with an inflatable balloon through which the device can be conveniently fixed and taken out. The front end of the guide wire penetrates the conical head of the microcatheter and facilitates radiography and re-hydrotubation.

Description

technical field [0001] The invention relates to a liquid-passing imaging recanalization device used in gynecology. Background technique [0002] Infertility is a common and frequently-occurring disease among women of reproductive age. Infertility caused by tubal obstruction has accounted for 30 to 50% of female infertility. Traditional methods such as surgery and laparoscopy have never been satisfactory. Examination is the gold standard for diagnosing fallopian tube obstruction. The traditional angiography method of injecting contrast agent through the uterine mouth is prone to false positives, and the false positive rate is about 30% or more in the literature. Therefore it is necessary to improve. Contents of the invention [0003] The task of the present invention is to provide a recanalization device for liquid-passing radiography. Catheter (2), inner cannula (3), outer cannula (4); outer cannula (4) and inner cannula (3) can be used in combination alone; or microcat...
