The spraying opening 11 is arranged in an outward and obliquely upward direction.

The two pesticide spraying units 7 are symmetrically arranged on the outer side of the cleaning unit 4.

Before the device is used, iodine solution is added into a left cavity and a right cavity of a liquid storage, a support plate 301 is fixed by an upper positioning pin 302, a piston 305 is positioned at the uppermost displacement, an elastic ring 406 is in an undeformed state, and a fixing ring 403 is positioned at the uppermost displacement; the baffle 14 is located at the uppermost end of the displacement and seals the spraying opening 11. For convenience of use, the lower end of the fixed barrel is provided with a downward protruding block 306, and the lower end of the vertical rod of the T-shaped rod 307 is located below the protruding block 306 and is provided with a handle.

When the device is used, one end of the opening of the fixed barrel is inserted into the body of a patient, the cleaning ball positioned below is positioned at the position of the cervical orifice, then one hand holds the convex block 306, the other hand pulls the T-shaped rod 307 up and down, and when the T-shaped rod 307 moves downwards, the pistons 305 on the left side and the right side are driven to move downwards together, negative pressure is formed in the sleeve 2 above the piston 305, and liquid medicine is sucked into the cavity of the sleeve 2 above the piston 305;

when the piston 305 moves downwards, the rope 8 is pulled to move downwards together, the downward movement of the rope 8 pulls the fixing ring 403 to move downwards along the guide groove 401, the diameter of the lower end of the conical funnel is smaller than that of the upper end of the conical funnel, so that the fixing ring 403 deforms inwards in the downward movement process, and the spring on the cleaning ball presses the cleaning ball to move inwards in the downward movement process of the fixing ring 403, so that the cleaning ball is close to the cervix, and the shape of the cervix of a human body is a cone with a large upper part and a small lower part, so that the cleaning ball can be always close to the junction of the cervix, and impurities at the junction can be sufficiently cleaned by the cleaning ball; when the rope 8 moves downwards, the elastic ring is pulled to move outwards to deform, so that the elastic ring gradually presents a flat oval shape, the rolling ball 407 can be always in contact with the position of the cervical orifice in the deformation process of the elastic ring, and mucus at the cervical orifice is cleared when the rolling ball 407 rolls.

When the T-shaped rod 307 moves upwards, the liquid medicine in the sleeve 2 is pushed into the space between the medicine coating barrel and the protective shell through the pipeline 10, and meanwhile, the T-shaped rod 307 moves upwards to enable the fixing ring 403 and the elastic ring to reset; the T-shaped rod 307 continuously moves up and down in a reciprocating manner, so that the cleaning ball cleans the joint of the scale column, and meanwhile, the elastic ring continuously deforms, so that the rolling ball 407 rolls to clean secretions at the position of the cervical orifice; and in the process that the T-shaped rod 307 continuously moves up and down, the liquid medicine is continuously pushed into the liquid medicine shell 701 and gradually enables the liquid medicine shell 701 to have moving pressure inside;

after cleaning for a certain time, the T-shaped rod 307 is pulled downwards, the T-shaped rod 307 moves downwards until the piston 305 contacts the support plate 301, the T-shaped rod 307 is pulled downwards continuously, the piston 305 can drive the support plate 301 to move downwards to be separated from the positioning pin 302 positioned above, when the support plate 301 moves downwards to the position where the positioning pin 302 positioned below fixes the support plate 301, the T-shaped rod 307 stops being pulled downwards, the T-shaped rod 307 is matched with the internal and external threads of the sleeve 2 in the process that the T-shaped rod 307 drives the support plate 301 to move downwards, and the T-shaped rod 307 moves downwards to enable the sleeve 2 and the cleaning unit 4 to rotate; and the downward movement of the T-shaped rod 307 can drive the foreign matter collecting shell 5 and the cleaning unit 4 to move downwards to be separated from the cervical orifice and positioned below the pesticide spraying unit 7; in the process that the foreign matter collecting shell 5 moves downwards, the L-shaped push rod 704 is driven to move downwards together, so that the baffle 14 moves downwards to finally open the medicine spraying opening 11, and the medicine liquid in the medicine liquid shell 701 can be sprayed out from the medicine spraying opening 11;

subsequently, the T-shaped rod 307 is continuously pulled to move up and down, so that the liquid medicine can enter the liquid medicine shell 701, and in the process that the T-shaped rod 307 continuously moves up and down, the sleeve 2 continuously rotates, the sleeve 2 rotates to drive the medicine spraying unit 7 to rotate together, and the medicine spraying port 11 sprays medicine on the biopsy position from different directions.

After the medicine coating is finished, the whole device is taken out of the body.

The device has the following advantages:

1, by arranging the liquid medicine shell 701, the piston 305 rod, the push plate and the medicine spraying port 11, when the device enters a patient body, the medicine spraying part is protected by the liquid medicine shell 701, the possibility that the liquid medicine is polluted by other secretions in the body is reduced, the medicine spraying port 11 is opened to carry out rotary medicine spraying treatment after the whole device enters the human body to be cleaned, and the whole medicine spraying experiment result can be more accurate;

2, by arranging the elastic ring, the rolling ball 407, the fixing ring 403 and the cleaning ball 404, the rope 8 can drive the elastic ring to deform continuously before medicine coating, the rolling ball 407 can clean secretions at the cervix, meanwhile, the cleaning ball 404 moves up and down to clean the joint of the scaly columns, and the secretions can be removed before medicine coating, so that the influence of the secretions can be prevented, and the accuracy of an experimental result can be ensured;

3, the cleaning unit 4 and the medicine spraying unit 7 are integrated and are arranged in the fixed barrel, so that the device can be placed into a patient body only once without inserting the device for many times during operation, discomfort of the patient can be relieved, the complexity of an operator is reduced, the operator only needs to insert the device into the patient body and pull the T-shaped rod 307 in a reciprocating manner, two actions of cleaning and spraying can be realized, and the operation is simpler;

4, through setting up rolling ball 407 and clearance ball 404, can prevent that traditional cotton swab is great to the patient friction when clearing up the secretion, produces the phenomenon of bleeding, and rolling ball 407 and clearance ball 404 contact with patient's cervical orifice position, both can clear up the secretion and can reduce the wound again, avoid bleeding to the influence of experimental result, not only more easy to use, more can improve the degree of accuracy of experiment.
