Minimally invasive abortion surgery is not scraping the uterus, usually choose to use a suction tube, under the action of negative pressure, the pregnancy sac in the uterine cavity as well as the meconium sucked out of the body. The damage to the patient’s uterine lining is minimized in this case, so the patient recovers faster after the procedure. Curettage is only used when there is residual abortion, or when there is residual drug abortion, or when the embryo has stopped developing and the tissue has been mechanized, and the adhesion with the uterine lining is dense. Curettage is generally a process of using a spatula to scrape out residual material that is more densely adhered to the uterus. Since this condition is more damaging to the patient’s uterine lining, it is not usually chosen, but only when it is necessary and is communicated to the patient.
