Manual rupture of the membrane is performed again to increase the probability of successful labor induction. At present, the commonly used two-chamber or three-chamber cervical balloon is used in clinical operations. In order to meet the requirements of cervical dilation, 60-80ml of normal saline needs to be injected into the uterine cavity and the balloon part of the vagina and cervix, and the mechanical expansion is performed. In the cervix, the patient feels a lot of discomfort, and the balloon in the uterine cavity stimulates the fetal head, which will cause fetal discomfort and heart rate changes, resulting in the failure of placing the balloon and losing the opportunity to mechanically dilate the cervix to promote cervical ripening.

If the mechanical dilation of the cervix can be successfully completed, the balloon will be removed to perform artificial rupture of the membrane. At present, the commonly used tools for artificial rupture of the membrane are needles, Alice forceps or vascular forceps. To complete the operation, two or three fingers need to be inserted into the birth canal for guidance, and manual rupture of the membrane is performed blindly based on experience and feeling; when the medical staff holds the needle to artificially rupture the membrane, the needle is likely to cause damage to the birth canal, and there is even a danger of injuring the baby , and when the patient's anterior amniotic fluid is low, acupuncture artificially ruptures the membrane, the depth of the puncture cannot be grasped, the probability of injury to the baby is greatly increased, and it is not easy to succeed, the operation efficiency is low, and the injury rate is high, which brings difficulties to the operation of medical staff.

At present, the commonly used tools for artificial rupture of membranes are needles, Alice forceps or vascular forceps. Medical staff cannot complete the operation under direct vision when artificial rupture of membranes is performed, and two or three fingers are needed to penetrate the birth canal for guidance. Feeling, blindly artificially rupture the membrane. When medical staff hold a needle to artificially rupture the membrane, the needle is likely to cause damage to the birth canal, and there is even a risk of injuring the baby; and when the patient's anterior amniotic fluid is low, acupuncture artificially ruptures the membrane, and the depth of the puncture cannot be grasped. The probability of injury to the baby is greatly increased. And it is not easy to succeed; because the amount of anterior amniotic fluid is very small, and even the fetal membrane is close to the fetal scalp. Even if the operation is successful, there is no amniotic fluid outflow, and it is impossible to judge whether the artificial rupture of the membrane is successful. Because the fetal membrane has two layers, often only one is clamped out. Layers of fetal membranes, mistakenly thinking that the rupture of the membrane was successful, but in fact the rupture of the membrane was unsuccessful, or even though the rupture of the membrane was successful, there was no amniotic fluid outflow, mistakenly thinking that it was unsuccessful, and repeated clamping again, the operation was time-consuming and laborious, and it also increased maternal discomfort. and increased risk of harm to the fetus. When using Alice forceps or vascular forceps for artificial membrane rupture, due to the limited length of the blood vessel forceps and the blunt top, the size of the rupture cannot be controlled, and the fetal membrane is easily clamped, which is easy to clamp the fetal scalp at the same time, with low efficiency and high injury rate. , which also brings difficulties to the operation of medical staff.
