The invention discloses a heart-shaped three-dimensional intrauterine device. The intrauterine device comprises a first annulus and a second annulus, wherein the upper parts of the first annulus and second annulus are wider than the lower parts; two side connecting reinforcements and two upper connecting reinforcements are arranged between the first annulus and the second annulus, the two upper connecting reinforcements are arranged on the tops of the first annulus and the second annulus, the two side connecting reinforcements are arranged on the lower parts of the first annulus and the second annulus, two first vertical reinforcements are arranged on the first annulus, two second vertical reinforcements are arranged on the second annulus; and a first annulus bending part which bends inward is arranged on the top of the first annulus, and a second annulus bending part which bends inward is arranged on the top of the second annulus. The invention can solve the problems of the prior art, greatly increase the contraceptive effect and effectively prevent the intrauterine device from dropping and displacing; and the top of the intrauterine device is depressed so that the intrauterine device can more effectively stick to the lining of the uterine cavity and the intrauterine device can be worn more comfortably and safely.
Description
Heart-shaped three-dimensional intrauterine device technical field The invention relates to an intrauterine device, in particular to a heart-shaped three-dimensional intrauterine device. Background technique The currently used IUDs mainly include metal single ring, gamma-shaped, T-shaped, M-shaped, U-shaped, etc., but metal single ring is the most. The IUDs mentioned above are all flat structures, which are prone to fall off and shift. In addition, due to the limited space occupied by the existing IUD in the uterine cavity, it is difficult to produce aseptic inflammation in a large enough area in the uterine cavity, thus making it difficult for the contraceptive effect to reach an ideal level. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a heart-shaped three-dimensional intrauterine device, which can solve the problems existing in the prior art, can greatly improve the contraceptive effect, can effectively prevent the occurrence of the fa...
