The invention will be further illustrated with reference to the accompanying figures 1-3 and example 1: a cervical leakage preventer comprises a water blocking block 1 and an air bag 2 outside the water blocking block;

in the prior art, only a simple air bag or a silica gel block is arranged, so that the main problem of the arrangement is that the air bag or the silica gel block can move continuously at the position of a cervix along with a hysteroscope, and a patient feels strong discomfort; in the process of continuous movement, the outflow phenomenon of uterine cavity expanding liquid still exists;

after the uterine cavity expanding liquid flows out seriously, the uterine cavity expanded by the uterine cavity expanding liquid can be contracted, the hysteroscope cannot perform imaging or operation better, and in order to ensure that the uterine cavity is in a certain opening degree in the examination or operation process, a water supplementing plug 3 is arranged, medical personnel can inject the uterine cavity expanding liquid through a water supplementing interface 6 at regular time or according to the imaging requirement, the uterine cavity can be ensured to be in the state of being expanded by the uterine cavity expanding liquid as much as possible, the precise imaging is facilitated, and the precise examination or operation is facilitated;

therefore, the front section of the air bag 2 is also provided with a water replenishing plug 3, the water replenishing plug 3 is provided with a water replenishing hole 4, and the water replenishing hole 4 is communicated to a water replenishing interface 6 at the tail end of the water plugging block 1 through a water replenishing channel 5 in the water plugging block 1;

in order to change the action of the existing fixed air bag or silica gel block in the action process of the hysteroscope, a movable air bag 22 is designed, the movable air bag 22 is movably fixed at the cervical orifice, when the hysteroscope works movably, the position of the movable air bag is fixed or the action is small, and the discomfort of a patient is reduced;
