For example, current induced abortion is mainly divided into negative pressure aspiration, clamp scraping, hysteroscopic induced abortion and the like. The negative pressure suction method is suitable for uterus within 10 weeks of gestation, mainly adopts a negative pressure electric suction method to suck out embryo sac and decidua tissues which are early gestation products, and is called as induced abortion negative pressure suction method or simply negative pressure suction method. The scope of the forceps scraping operation is generally claimed to be within 14 weeks, and for the patients who are required to terminate pregnancy or are unsuitable for pregnancy due to special conditions such as diseases or other abortion methods, a combined forceps clip and negative pressure suction operation method is generally used for terminating pregnancy. Negative pressure aspiration and forceps scraping are blind probes, and all depending on the experience of doctors, there is a risk of incomplete abortion, excessive injury, or uterine laceration. Hysteroscopic surgery involves placing hysteroscopic and surgical instruments into the uterine cavity under anesthesia through the vagina, and taking out embryos and collateral tissue or resecting tumors under direct vision through the operative aperture.
