宫颈松弛是宫颈发育不全或宫颈裂伤导致的宫颈机能不全，是晚期反复流产的主要原因。宫颈松一般的医院建议在怀孕14-16周期间做孕期的宫颈环扎，手术是在宫颈外口用丝线缝合，而且术后要长期卧床，容易出现感染是一方面，另一方面丝线的承受力不好，若是发动宫缩很难保住孩子，所以成功率不足20%。

　　Cervical relaxation is the cervical hypoplasia or cervical laceration, which is the main cause of late repeated miscarriage. The general hospital of cervicitis recommends that during the 14-16 weeks of pregnancy, the cervix ring of pregnancy be performed. The operation is sutured with silk thread in the outer part of the cervix, and long-term bed rest after surgery. It is easy to have infection on the one hand, and on the other hand, silk thread. The tolerance is not good. If you launch a contraction, it is difficult to keep the child, so the success rate is less than 20 %.
