A uterine expansion instrument for treating uterine diseases in obstetrics and gynecology

Abstract

The invention discloses a uterine expander for treating obstetrics and gynecology uterine diseases, which belongs to the technical field of uterine expanders for obstetrics and gynecology. A uterine expander for treating obstetrics and gynecology uterine diseases includes; Shell; it is specifically columnar, and the upper diameter is smaller than the lower diameter, and semi-elliptical shallow openings are provided on the front and rear sides of the upper part to fix the duckbill. By pressing the airbag, the anti-off support, the expansion part and the limit locking mechanism can be attached to the cervical wall of the uterus under the action of air pressure, and the inner diameter of the expansion part can be adjusted according to the treatment cycle, so that the diameter of the expansion part can be adjusted at any time , to meet the treatment requirements, at the same time, under the state of internal air pressure, the ejector rod makes the connecting rod stretch out, so that the expanded part is stretched out and contacts the inner wall of the cervix, which can prevent it from falling off; the internal filling of the limit locking mechanism After the gas is released, the limit locking mechanism is opened to contact the bottom of the cervix, so that the inside and outside are combined, so that the device can be firmly attached to the cervix.

Description

technical field [0001] The invention belongs to the technical field of uterine expanders for obstetrics and gynecology, and in particular relates to a uterine expander for treating uterine diseases in obstetrics and gynecology. Background technique [0002] Cervical atresia and stenosis are abnormalities of the cervix and common causes of infertility. Congenital cervical atresia or stenosis is mostly due to the formation and incomplete fusion of the lower segment of bilateral Müllerian ducts. Clinically rare, often accompanied by uterine hypoplasia, most of the secondary sexual characteristics are normal. If the endometrial function of the patient is good, periodic lower abdominal pain may occur due to hemorrhage in the uterine cavity during puberty, or hypomenorrhea accompanied by dysmenorrhea, and menstrual blood may flow back into the abdominal cavity through the fallopian tubes, causing pelvic endometriosis. Acquired cervical atresia and stenosis are more common after ...

Problems solved by technology

The main reason is that the cervical dilatation is insufficient during aspiration, or the straw is taken out with negative pressure, causing endocervical damage and wound adhesion atresia

[0003] One of the common diseases of the uterus when the cervical canal is atresia. The clinical treatment method is generally carried out by physical means. The patients need regular cervical dilation surgery. The existing dilation methods use different types of dilators. Lying on the bed, and the end of the dilator is exposed at the vaginal opening, this treatment process will cause a lot of inconvenience to the patient, and each type of dilator is performed according to the treatment cycle, too small will increase the treatment cycle, and too large will increase the treatment cycle Injury to the patient's genitals
