[0013] Preferably, the mounting ring and the delivery pipeline are connected by a support rod, and the support rod and the delivery pipeline are rotationally connected, and an elastic telescopic structure is formed between the support rod and the mounting ring via a second spring.

[0014] Preferably, a suction tube is fixedly connected and installed on the outer surface of the drug storage capsule, and the suction tube is snap-connected with a fixed buckle fixedly installed on the outer surface of the drug storage capsule.

[0015] Preferably, the adjustment mechanism includes a mounting column for installing the spray head, and the spray head is provided with through holes distributed at equal intervals, the mounting column is threadedly connected to the delivery pipe, and a connecting hole is provided inside the mounting column, and the connecting hole corresponds to the position of a sealing block fixedly installed inside the delivery pipe, and the connecting hole and the sealing block are both arranged as truncated cone structures.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the medical device for treating cervicitis and cervical HPV infection adopts a new structural design, and its specific contents are as follows:

[0017] 1. An expansion mechanism is provided. When the device is used, the expansion plates on the left and right sides of the delivery pipe follow the device into the patient's vagina. Then, the expansion plates on the left and right sides rotate outward to expand the patient's vagina, thereby reducing the friction between the delivery pipe and the patient's body when the delivery pipe is inserted, and reducing the patient's discomfort;

[0018] Furthermore, the expansion mechanism and the hand-held finger ring are linked to each other. The operator presses the hand-held finger ring inward to move the hand-held finger ring relative to the conveying pipe. At this time, the expansion plate is driven to rotate by the connecting rod to achieve the purpose of expansion. At the same time, the connecting rod is a telescopic structure and the hand-held finger ring can be reset under the pushing action of the first spring.

[0019] Furthermore, the expansion plate is rotatably installed on the outside of the mounting ring, and the mounting ring and the conveying pipeline are connected by a support rod. The support rod is rotatably connected to the conveying pipeline, and the support rod is movably connected to the mounting ring, so the conveying pipeline can change direction at will inside the mounting ring, thereby facilitating operation by operators.

[0020] 2. The outside of the drug storage capsule is connected to a suction tube, and the expansion of the drug storage capsule is used to generate negative pressure inside, so that the drug solution to be used is sucked into the interior through the suction tube, which can reduce the contact between the operator and the drug solution and avoid contamination;

[0021] 3. An adjustment mechanism is set up. The spray head and the delivery pipeline are connected by a mounting column thread. The relative distance between the internal connection hole and the sealing block is changed by rotating the mounting column, thereby adjusting the gap between the two, and ultimately achieving the purpose of changing the drug flow rate and controlling the overall drug output.
