Uterus anti-adhesion stent for preventing and treating uterine cavity adhesion and use method thereof

Abstract

The invention relates to the technical field of uterus anti-adhesion stents, and particularly relates to a uterus anti-adhesion stent for preventing and treating uterine cavity adhesion and a use method thereof. The uterus anti-adhesion stent comprises an outer coating, a first stent and a second stent. The uterus anti-adhesion stent improves uterine cavity adhesion through the outer coating, theinner support selects polypropylene PP double stents, the inner support and the polypropylene PP double stents are matched for use, the inner support is opened into an inverted wine glass shape and can be infinitely matched with the uterine cavity, the contraction form is in a 1 shape, the outer coating is a nano silica gel drug coating, the designed stent material is non-toxic and harmless, the first stent and the second stent are combined and unfolded to be matched with the uterine cavity, the contraction form is small and smooth, and taking and placing are easy; and the outer coating is a nano silica gel biological film with micropores, the filler in the outer coating material contains chitosan, the chitosan can be gradually degraded and released along with the biological film, the defect that only one-time injection can be achieved after hysteroscopy is overcome, the effect disappears after one or two days, and the effect can be continuously achieved in the high-incidence period ofuterine cavity adhesion.

Description

technical field [0001] The invention relates to the technical field of stent equipment, in particular to a uterine anti-adhesion stent for preventing and treating uterine intrauterine adhesions and a method for using the stent. Background technique [0002] Intrauterine adhesion (IUA) is caused by a variety of reasons resulting in damage to the basal layer of the endometrium, thinning or defect of the endometrium, adhesion or fibrosis, resulting in partial or complete closure of the uterine cavity. The clinical manifestations are decreased menstrual flow, amenorrhea and infertility, which seriously affect the reproductive and physical and mental health of women of childbearing age. At present, the incidence of IUA in my country is very high, and uterine cavity surgery is the main cause of IUA. It is reported in the literature that the incidence of IUA caused by artificial abortion and curettage is as high as 25%-30%. In addition, the rate of adhesion after hysteroscopy is ev...

Problems solved by technology

[0003] The object of the present invention is to provide a uterine anti-adhesion support for preventing and treating uterine intrauterine adhesions and its use method, so as to solve the above-mentioned background technology that the current uterine anti-adhesion support cannot effectively avoid the adhesion of uterine wounds , easy to cause aseptic inflammation and increase the chance of adhesion
