Abortion surgery is divided into: ordinary abortion surgery, painless abortion surgery, superconducting painless abortion surgery, painless hysteroscopic abortion surgery and so on. Comparatively speaking, painless abortion surgery under superconducting monitoring is better, because it is carried out under anesthesia without pain to the patient, and the surgeon carries out the surgery under the direct vision of superconducting monitoring, which is safer, so the surgery is relatively better. Before the operation, we should carry out some routine examination, ultrasound examination, to understand the size of the gestational sac and the location of the bed; routine examination of leukorrhea, to understand whether there is inflammation of the vagina. If the abortion is painless, an electrocardiogram, routine blood test and infectious disease test will also be performed. If there is no abnormality in the preoperative examination, the patient can choose to terminate the pregnancy with painless abortion under the superconducting monitoring.
