Description

Improved vaginal speculum

Technical Field

The utility model relates to the technical field of medical supplies, concretely relates to modified vaginal speculum.

Background

The conventional vaginal speculum can be widely used in the field of obstetrics and gynecology, and the currently used double-blade speculum can keep the front wall and the rear wall of the vagina apart, so long as the patient does not have too much lax vaginal tissue and provides enough illumination to expose the cervix, but in some women, the double-blade speculum is used, the space between the left side wall and the right side wall of the vagina collapses and blurs the view of the cervix, which is frequently generated in patients with high yield, pregnancy and obesity. However, even if the vagina is opened to the maximum extent, the exposure limitation exists due to the relaxation of the vagina of a part of patients under the irradiation of external light. Especially, as the pregnancy period of the female in the gestational period increases, the supporting force of the pelvic floor structure is gradually weakened, and is particularly remarkable in the middle and late pregnancy.

The inventor finds that when women with obesity and gestation are in gynecological operation, the current situation that the vaginal wall bulges and is not beneficial to exposing the cervix is often found, the total weight and the volume of the uterus during pregnancy are continuously increased along with the increase of the number of weeks of pregnancy, the total weight and the volume can be increased to 20 times of the original weight before delivery, and the occurrence of the situations is aggravated due to the change of the estrogen level in the body, so that the shielding is caused, and the clinical operation is inconvenient. That is to say, the existing vaginal speculum cannot be completely opened when opening the vagina, and is not convenient for medical staff to check.
