The invention discloses a novel vaginal irrigator used for gynecology. The irrigator includes a cannula, four rubber rings are axially distributed on the outer side surface of the cannula, the parts,located between adjacent rubber rings, of the side surface of the cannula are provided with spray holes, and the part, corresponding to each rubber ring, of the inner side surface of the cannula is provided with a supporting rod; and the upper end surface of the cannula is provided with a round head, and the opening position of the lower end surface of the cannula is provided with an end cap. According to the novel vaginal irrigator, the outer side of the cannula is connected with the rubber rings, the rubber rings can be folded relative to the cannula, when the rubber rings are shrunk, the overall diameter is reduced, so that the cannula can be conveniently inserted into a vagina; when the rubber rings are expanded, the cannula and a vaginal wall form a supporting cavity, so that a cleaning liquid can conveniently make full contact with the vaginal wall; at the same time, the rubber rings can prevent the cleaning liquid from retrograding, so that unnecessary infection of a uterine cavity can be reduced; a liquid discharge pipe can collect wastewater, so that the wastewater can be conveniently subjected to unified treatment, and cross infection can be avoided; and the positions ofpress sheets can be controlled by a movable shaft, so that the irrigator is convenient to operate, and the cleaning efficiency is improved.
