Description

Oviduct contraceptive device, implanting device and extracting device

Technical Field

The invention relates to the technical field of reproductive medicine, in particular to an oviduct contraceptive device, an implanting device and an extracting device.

Background

Birth control techniques, or methods of contraception, are a long-standing technique. Historically, there have been methods of medical fluid irrigation of the vagina (uterine cavity) after sexual life, and the use of animal tissue as the primary condom. It is a harsh criminal method for violently destroying (removing) the gonads or reproductive organs of males or females. Recently, with clear understanding of the anatomical structure of the genital organ of both sexes and progress of surgical operation, birth control can be achieved by vasoligation or vasoligation. However, such surgical methods can result in the person undergoing surgery not being reproductive.

Currently, condoms (including both males and females), intrauterine devices (mainly contraceptive rings), and female contraceptives (including oral administration, subcutaneous implantation, etc.) are commonly used as contraceptive means. Wherein, the male condom is most convenient and wide to use, has low single cost and can protect STD (sexually transmitted disease) to a certain extent. The disadvantage is that the sexual satisfaction can be affected, and the sexual life has a certain failure rate (including improper use and poor product quality). The functional contraceptive device (contraceptive ring) is a female contraceptive device widely used all over the world, and the principle of the device is that endometrium is stimulated in uterine cavity through metal to cause aseptic inflammation, a certain amount of metal ions are slowly released to interfere the fertilization process of ovum or interfere implantation of fertilized ovum. It has the disadvantages of inflammation of uterus, severe allergy and infection of uterus and adnexa in some women, and harm to women's health. Generally, the contraceptive ring needs to be taken out after 10-15 years of operation, and the contraceptive ring is placed again after the endometrium is completely repaired.

The ordinary intrauterine device has the probability of slipping out from the uterus, so that the birth control (contraception) fails, the biological compatibility of the ordinary intrauterine device is not high, the discomfort after being implanted into a human body is easily caused, a long repairing period is needed after being implanted, the intrauterine device is not easy to take out after being implanted for a long time, the adhesion is easily caused, and the pain is caused in the taking-out process.
