When you go into the operating room, you first have to change into clean clothes from the hospital operating room, take your pants off and sleep on the operating bed. The nurse comes over to give you an intravenous injection and push the anesthetic down. After you fall asleep, the surgeon starts to do the surgery down there. The first step is to disinfect the vulva and vagina, then use a vaginal dilator to open the vagina, use a probe to explore the depth of the uterine cavity, and then use a special suction tube to suction the embryo out of the uterine cavity, and after suctioning out the embryo, the doctor observes the amount of bleeding after the operation. If there is not much bleeding, the doctor can end the operation and remove the instruments. By this time, the patient has probably begun to wake up, and when he wakes up and gets dressed, he can go to the observation bed and rest again, and he can usually go home after resting for half an hour or so.
