Why does cervical laceration occur during abortion?
Cervical laceration may occur during artificial abortion (abbreviated as artificial abortion), which often occurs in first-time abortion patients. Cervical laceration is an important cause of cervical insufficiency. It is mainly a laceration of the internal cervical opening. In severe cases, the cervix is ​​completely torn and even extends to the lower part of the uterus. Possible causes of cervical laceration are: ① The cervical canal is tight, the number skips when the cervix is ​​dilated, and the surgical operation is rough. ② The fetal limbs in the uterus are large and the local tissue is scratched when they are taken out. Most cervical lacerations do not necessarily have any symptoms. The main manifestation is that the cervical canal suddenly becomes loose from tight. The amount of bleeding is usually not much, and heavy bleeding is rare.

Mild cervical lacerations can be stopped by applying pressure with gauze strips, while larger cervical lacerations require interrupted sutures with intestinal sutures. If the laceration is large and not repaired at the time, it may lead to incompetent internal cervical os and habitual miscarriage in the future.
