我怀孕22周 羊膜襄膨出 医生说有可能宫劲机能不全 流产的，听朋友介绍宫颈埋箍治疗可以救胎儿，请问北京三院有这样的技术吗?I was pregnant 22 weeks of amniotic puffing doctor said that it is possible to have incomplete abortion, listening to a friend's introduction of cervix could save the fetus, excuse me Beijing three hospital has such a technology?

　　宫颈埋箍是陈凤林教授发明，只有北京安太医院才有这样的技术，北医三院没有的，北京安太医院还可以签约治疗的!The cervix is the invention of Professor Chenfenglin. Only Beijing Antai Hospital has such technology. There is no Beijing Medical Third Hospital. Beijing Antai Hospital can also sign up for treatment!
