Because the shapes of the cervical orifice of a female after birth (the cervical orifice is in a transverse split shape) and the cervical orifice of a female without birth (the cervical orifice is in a round shape) are different, the cervical orifice of a female after birth is difficult to be completely attached to the cervical orifice of the female after birth, when the female after birth needs to be inspected in a uterine cavity, medical staff inserts the inner tube 5 into the uterine cavity of a patient, and then rotates the two operating rods 1503 clockwise (taking a left viewing direction as an example), the two operating rods 1503 drive the circular ring 1504 and the rotating sleeve 1502 to rotate clockwise together, the rotating sleeve 1502 starts to move leftwards under the action of the threads of the outer tube 3, the rotating sleeve 1502 drives the sliding sleeve 1501 to move leftwards together, the limiting grooves of the sliding sleeve 1501 start to squeeze the adjacent limiting rods on the uterine neck 4, the two limiting rods start to move oppositely, the two limiting rods cause the uterine neck 4 to deform, so that the uterine neck 4 starts to be flattened by adapting to the transverse split cervical orifice of the female, and the cervical orifice 4 is enabled to be evenly attached to the cervical orifice of the patient, and the cervical orifice of the cervical orifice is prevented from being leaked or from being leaked from the cervical orifice of the patient.
In the process that medical staff rotates two operation rods 1503, two operation rods 1503 move circumferentially along the adjacent limit rings 1506, meanwhile, the limit rings 1506 limit the two operation rods 1503, the situation that the operation rods 1503 move leftwards due to control deficiency of medical staff in the rotating process is avoided, thus the cervical plug 4 moves leftwards, the cervical plug 4 is excessively contacted with a cervical opening, even damage is caused to a patient, after the shape of the cervical plug 4 is adjusted, the medical staff pulls the right ends of the two operation rods 1503 back by using fingers, at the moment, the operation rods 1503 and the adjacent limit rings 1506 lose limit fit, then the medical staff moves the two operation rods 1503 leftwards, the two operation rods 1503 drive the circular rings 1504 to move leftwards together, the circular rings 1504 start to press the two push rods 1505 leftwards, the two push rods 1505 drive the cervical plug 4 to move leftwards together until the cervical plug 4 blocks the cervical opening of the patient, then the medical staff performs operations such as flushing, uterine expansion, checking and the like, and after the checking of the cervical cavity of the patient is finished, the medical staff can separate the device from the patient integrally.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
