Description

Gynaecology and obstetrics is with expanding palace device

Technical Field

The invention relates to the technical field of gynecological instruments, in particular to a uterine dilator for obstetrics and gynecology.

Background

The obstetrics and gynecology department is one of four main subjects of clinical medicine, and is mainly used for researching the etiology, pathology, diagnosis and prevention of female reproductive organ diseases, the physiological and pathological changes of pregnancy and childbirth, the prevention and diagnosis and treatment of high-risk pregnancy and dystocia, female reproductive endocrine, family planning, female health care and the like. In gynecological examinations and surgeries, it is often necessary to dilate the cervix of a patient with different types of cervical dilators in order to provide an adequate surgical field of view. For gynecological procedures performed from the vagina, such as cervical conization, scrotal hysterectomy, etc., it is often necessary to open the vagina, exposing the cervix and surrounding tissue.

In the prior art, different types of cervical dilators are often used for dilating the cervix of a patient, so that the dilation effect is not stable enough, and pain and psychological stress are easily caused to the patient; meanwhile, the existing cervical dilator has limited exposed examination visual field, and the moving range of the examination instrument is limited.
