Background

Uterine curettage refers to an operation of scraping the endometrium or the uterine cavity contents. The small operation commonly done in obstetrics and gynecology is one of the artificial abortion methods. It is divided into diagnostic uterine curettage and therapeutic uterine curettage. Has certain risks and complications. The curettage is divided into general curettage and segmental curettage. The general use of curettage is applicable to endocrine disorders requiring understanding of endometrial changes and the response to sex hormones, whether ovulation occurs or not, whether tuberculosis occurs or not, and the like. The segmental scraping means firstly scrapes the cervical canal and then scrapes the uterine cavity when in operation, and the scraped objects are respectively sent to pathological examination, so the segmental scraping means is suitable for diagnosing cervical cancer, endometrial cancer and other malignant tumors of the uterus, and can know the cancer range. Therapeutic uterine curettage is divided into suction curettage and forceps curettage. Suction and curettage are to suck the content in the uterine cavity by a negative pressure suction pipe, and forceps curettage is to take the content in the uterine cavity by oval forceps and then to curettage the uterine cavity. The indications for therapeutic uterine curettage are: the early pregnancy requires the termination of pregnancy, the aspiration and curettage is used within 3 months of pregnancy, and the forceps and curettage are used for removing the residual matters in the uterine cavity after more than 3 months and induction of labor; incomplete abortion, intractable abortion, retained placenta, and grape fetus.
