Abstract

The invention discloses a recoverable umbrella-shaped fallopian tube intrauterine device. The intrauterine device comprises a tube body. The top end of the head of the tube body is provided with an agnail which is of an umbrella-shaped structure. The end of the tube body is provided with a ring body which is of a flat-shaped hollow structure. The ring body is provided with a through hole. A barb and calabash-like protrusions are arranged between the agnail and the ring body. The agnail, the barb, the calabash-like protrusions, the ring body and the tube body are of an integrated structure. A conveyor is a medical plastic catheter. The recoverable umbrella-shaped fallopian tube intrauterine device is reasonable in structure and design. Due to the fact that the intrauterine device is manufactured by using the integrated structure and high molecular materials, the intrauterine device is safe and reliable, the occurrence of salpingitis after placing the device is decreased, and the effectiveness of blocking the fallopian tube after placing the device is guaranteed. Together with other contraception measures, the intrauterine device can be used for the contraceptive operation on women of childbearing age. The intrauterine device has the advantages of being free from surgery and pain, and convenient to operate. The intrauterine device is an efficient, safe, non-toxic, deformity free, non-carcinogenic, reversible and complication free contraceptive tool and is acceptable by most of the women of childbearing age.

Description

technical field [0001] The invention relates to a contraceptive device, in particular to a reversible umbrella-shaped tubal contraceptive device. Background technique [0002] Tubal birth control plays an important role in population control in both developing and developed countries. A variety of methods have been used clinically, and there are more than ten kinds of IUDs at home and abroad, but most of them have the disadvantage that women's fallopian tubes are vulnerable to damage, and once they need to have a child, they must undergo a reversal operation, or even after reversal, they still cannot bear children. And there are certain side effects and dangers if placed for a long time. There are many ectopic pregnancies after IUD placement, salpingitis and endometriosis often occur, and gestational sacs often implant in the fallopian tubes and develop and grow. [0003] At present, the hysteroscopic Essure / Adiana microembolization tubal sterilization approved by the Foo...
