The operation process of curettage surgery is as follows: first, the doctor first needs to disinfect the patient’s vulva and vagina, then lay a sterile cavity towel, then do a gynecological examination to determine the size and front and back of the patient’s uterus, so that in the process of surgery, the depth of the patient’s uterine cavity will be more bottom, to avoid the probe into the uterus is too deep, resulting in perforation of the situation. Second, the surgeon needs to use a speculum to open the woman’s vagina, expose and disinfect the cervix, use a cervical forceps, clamp the cervix, use a probe to find out the depth of the uterine cavity, and then use a dilation rod to dilate the patient’s cervix to 6.5-7.5. Third, a suitable spatula is selected to enter the patient’s uterine cavity and the patient’s endometrium and mucosa in the cervical canal are scraped in sections. Fourth, the scraped endometrium is placed in a pathology bag and sent for pathological examination. If the patient does not bleed much, the procedure is finished with further disinfection.
