Abstract

The utility model provides a disposable vagina plugging device for a laparoscope hysterectomy, which comprises a vagina elastic water sac, wherein the front end and the rear end of the vagina elastic water sac are respectively connected with an inner tube and a hollow hose. The back end of the vagina elastic water sac is also connected with an adhesive film. The syringe is embedded into the port at the tail end of the hose, and the physiological saline is injected into the vaginal elastic water sac until the vaginal elastic water sac is fully attached to the inner wall of the vagina, so that the effects of air blocking and sealing are achieved. The one-way valve can prevent the reverse flow of the physiological saline. If the vagina of a patient is loose or air leaks during the operation, a proper amount of normal saline can be injected by the injector at any time to increase the internal pressure of the sac, so that the device is prevented from slipping or leaking air. After the vaginal stump is sutured, the adhesive film is uncovered, part of physiological saline in the elastic water sac is pumped out, and the hollow hose is held by hand and pulled outwards, so that the intravaginal device can be easily taken out. If the vagina of the patient is fragile, the hollow hose at the front part of the one-way valve can be cut off, and the device can be taken out after the physiological saline in the vagina elastic water sac 1 is discharged.

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a disposable vagina plugging device for a laparoscopic hysterectomy.

Background

In the laparoscopic total hysterectomy, carbon dioxide gas is injected into the abdominal cavity of a patient in the early stage to establish pneumoperitoneum, and certain pressure of the pelvic cavity and the abdominal cavity is maintained to ensure the sufficient exposure of the surgical field, so that the smooth development of the surgical operation is ensured. However, after the uterus is resected and removed from the vagina during the operation, the pelvic cavity communicates with the outside through the vaginal stump, resulting in leakage of carbon dioxide gas. The gas leakage phenomenon makes the pneumoperitoneum pressure difficult to maintain, not only makes the operation of a doctor difficult and the operation time prolonged, but also the leaked carbon dioxide gas can reduce the air quality in the operating room and is harmful to the health of medical staff.

In order to solve the problems, in the process of laparoscopic total hysterectomy, after the uterus is resected, the vaginal stump which is not sutured yet needs to be blocked. The traditional method is to use disposable sterile medical gloves and gauze filled with normal saline to make a simple vaginal blockage device which is filled in the vagina, but the effect is not satisfactory. The disadvantages are that: 1. the sterilized gloves after being irrigated are soft and irregular in shape, are difficult to completely block the vagina and are easy to slip. 2.
