Description

Uterine curettage device for obstetrics and gynecology department

Technical Field

The invention relates to the technical field of medical instruments, in particular to a uterine curettage device for obstetrics and gynecology department.

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 two categories, diagnostic curettage (abbreviated as curettage) and therapeutic 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. Medical personnel utilize the curette to scrape off when carrying out the uterine curettage operation, and traditional curette is easy when using and is gone deep into the in-process in utero and cause the injury with the endometrium, scrapes the tissue of leaving simultaneously and is difficult to collect, needs a gynaecology and obstetrics to use curettage device for this reason.
