安太环能保到足月而环扎不行，为什么呢?因为传统的环扎，是用手术的丝线把松的宫颈扎紧的，但是最大的缺点就是承重力不好，随着孕周的增加，环扎的丝线容易断开，或者宫颈自己撕裂，最后还是流产。

Antaihuan can keep to the full term, but encircling can't, why? Because the traditional encircling, is to use the surgical silk thread to tie the loose cervix tightly, but the biggest disadvantage is that the bearing capacity is not good, with the increase of gestational age, the encircling silk thread is easy to break, or the cervix itself tears, and finally miscarriage.

我们的安太环是一个生物箍，就象手上带戒指，是直接套在宫颈内口的，承重力非常好，即便宝宝长的又高又胖也能承得起那个重量。并且我们的安太环治疗不用长期卧床保胎，而传统的环扎是需要卧床的

Our antaihuan is a biological hoop, just like a ring on the hand, which is directly put on the inner mouth of the cervix. It has a very good bearing capacity, even if the baby is tall and fat, it can bear that weight. And we don't need to stay in bed for a long time to protect the fetus, while the traditional encirclement needs to stay in bed
