Description

Anti-adhesion device in gynecological uterine cavity postoperative cavity

Technical Field

The invention relates to the field of medical instruments, in particular to a gynecological intrauterine postoperative intra-cavity anti-adhesion device.

Background

Intrauterine adhesions are mainly due to intrauterine adhesions after excessive damage to the endometrium. Generally, the intrauterine adhesion is discovered only when the menstrual flow is low or the menstrual blood cannot be discharged during menstruation. Intrauterine adhesion this kind of endometrial destruction is mostly associated with pregnancy. Many people who make artificial abortion after repeated pregnancy can cause excessive damage to endometrium and uterine cavity adhesion. The surgical treatment of the intrauterine adhesion is mainly hysteroscopic surgery at present, can be more intuitive under the hysteroscope, has better effect and can solve the problem of adhesion. If there is adhesion in any place, it can be directly released. After general operation, a ring is put in the uterine cavity, and the purpose is to prevent the uterine cavity from being adhered again.

The device for preventing the ring from adhering has more problems, firstly, the adhesion preventing area is smaller and is mostly placed at the uterine orifice, and the adhesion problem on partial positions can also occur subsequently; secondly, the anti-sticking ring has a small using area, so that the anti-sticking ring has large tightness when being used, and a patient suffers great pain and has long duration during the recovery period; third, the anti-adhesion ring is contaminated with bacteria by exchange of external body fluids during menstruation, which poses a greater risk of infection of the uterine orifice.
