宫颈环扎成功率有多高?How high is the success rate of cervix ring ligature?

陈凤林教授指出：宫颈环扎成功率不足20%左右。一般是在妊娠16-20周左右将宫口用丝线环扎，缺陷是缝扎的只是外口,一旦宫缩发动,不能有效阻止宫颈扩张,且易诱发宫缩而流产，缝扎后还容易引起宫颈管感染，导致胎膜早破流产。

Professor Chenfenglin pointed out: The success rate of cervix is less than 20 %. Usually around 16-20 weeks of pregnancy, the mouth of the palace is wound with silk thread. The defect is that the incision is only external. Once the contractions are initiated, they can not effectively prevent the expansion of the cervix, and they can easily induce contractions and miscarriages. It is also easy to cause cervical canal infection., Causes premature rupture of the fetal membrane.

而目前有安太环新技术可以在孕前就能完成宫颈埋箍。

At present, there is an new technology of Antai Ring that can complete the cervix implantation before conception.

创新点和学术价值：在孕前手术避免了缝扎导致流产的可能性，也不会导致宫颈感染。将“安太环”埋在宫颈内口的肌肉内，有效阻止宫颈内口的扩张。

Innovation and academic value: preconception surgery avoids the possibility of suture leading to miscarriage and does not lead to cervical infection. Bury "Antai Ring" in the muscles of the cervix, effectively preventing the expansion of the cervix.
