Description
Technical field
This utility model relates to a kind of medical field prevention uterus intrauterine adhesion device, and more particularly, it relates to the barrier film of a kind of artificial abortion's of being used for postoperative prevention uterus intrauterine adhesion.
Background technology
Intrauterine adhesion (intrauterine adhesion.IUA) claim the Asherman syndrome again, show as the few or amenorrhea of menstrual blood volume, periodic abdominalgia, pregnancy early midtrimester abortion, repeatedly or habitual abortion, missed abortion, ectopic pregnancy, premature labor, fetal death in utero to reach the Placenta Hominis plantation unusual etc., have a strong impact on women's physical and mental health.Any destructive factor of endometrium that causes all can cause intrauterine adhesion, be common in the artificial abortion or the spontaneous abortion dilatation and curettage after.The intrauterine adhesion that non-gestation causes, as hysteromyoma evidement, diagnostic curettage art etc., comparatively rare.Have the scholar find the incidence rate of 1 operation back intrauterine adhesion be 6.3%, 2 time be 14%, and the person is 32% more than 3 times, prompting artificial abortion meeting increases the adhesion incidence rate, the many more probabilities of number of times are high more, and missed abortion and easier the sticking together of the residual person of Placenta Hominis.
In recent years along with the popularization and the application of artificial abortion's technology, artificial abortion's number, repeat artificial abortion's number of times cumulative year after year, the incidence rate of the postoperative intrauterine adhesion that causes thus also rises thereupon.The intrauterine adhesion exclusion is the main Therapeutic Method of present IUA under the hysteroscope, and it is that direct-view separates down or the interior adhesion of excision uterine cavity targetedly, mainly contains mechanicalness operation and the operation of energy apparatus.The former postoperative forms the few but anthemorrhagic difficulty in the art of cicatrix, and latter's haemostatic effect is good, operating time short but more easily form cicatrix.Have that intrauterine adhesion exclusion tissue adhesion relapse rate is 3.1～23.5% under the bibliographical information hysteroscope, the severe adhesion relapse rate is up to 20～62.5%.How to reduce the difficult problem that adherence recurrence also is a clinical treatment.
