The working principle of the invention is as follows:

firstly, by rotating the T-shaped circular truncated cone 201 clockwise, since the ball 2021 on the rotating table 202 is clamped in the first sliding groove 2011 and the second sliding groove 2012, when the T-shaped circular truncated cone 201 rotates, the rotating table 202 moves upward along the axis direction of the T-shaped circular truncated cone 201, so as to drive the connecting seat 2022 to move upward, and thereby the medicine storage tube 301, the connecting tube 302 and the first medicine discharge nozzle 303 are screwed out of the end face of the supporting portion 1, (as shown in fig. 12), since one end of the second sliding groove 2012 close to the end face of the supporting portion 1 is closed, the rotating table 202 can be limited, so that the rotating table 202 and the T-shaped circular truncated cone 201 can be prevented from falling off, and the problem that the device cannot be normally used can be solved;

when the rotating table 202 moves to the position limited by the second sliding groove 2012, the T-shaped circular truncated cone 201 rotates to drive the connecting rod 402 to rotate along with the T-shaped circular truncated cone 201, so that the first transmission gear 401 on the connecting rod 402 rotates along with the T-shaped circular truncated cone 201, and the number of the connecting rod 402 and the first transmission gears 401 is eight, so that when the first transmission gear 401 rotates along with the T-shaped circular truncated cone 201, the first transmission gear 401 is engaged with the second transmission gear 403 to drive the second transmission gear 403 to rotate, and when the second transmission gear 403 rotates, because the rotating direction of the T-shaped circular truncated cone 201 is clockwise rotation (based on fig. 1), the rotating direction of the second transmission gear 403 also rotates clockwise, so that the second transmission gear can drive the incomplete gear 404 to rotate through the ratchet assembly, and when the toothed portion of the incomplete gear 404 is engaged with the rack 407, the rack 407 is driven to move toward the normal saline injector 405, so as to drive the driving rod 408 to move, thereby driving the piston rod of the saline injector 405 to move, so that the saline in the saline injector 405 is ejected to the first drug outlet nozzle 303 through the second drug outlet nozzle 4051, meanwhile, in the process of continuously screwing out the medicine feeding mechanism 3, the physiological saline in the physiological saline injector 405 is also sprayed out to the air bag plate 3025 and the abutting rod 3027 through the second medicine outlet nozzle 4051, thereby wetting the first medicine ejection head 303, the air bag plate 3025 and the abutment lever 3027, this makes it possible, when the first discharge nozzle 303, the air bag plate 3025 and the abutment lever 3027 are inserted into the nasal cavity, to prevent irritation of the nasal mucosa, meanwhile, the nasal polyp inserting device is smoother in the inserting process, and human tissues in the nasal cavity cannot be pulled, so that the discomfort of a patient during medicine application on the nasal polyp can be reduced;

when the first medicine discharging nozzle 303, the air bag plate 3025 and the abutting rod 3027 are inserted into the nasal cavity, the pressing block 305 is then pressed, so that the push rod 304 moves, when the push rod 304 moves, the piston plate 3027 can eject the medicine liquid in the medicine storage tube 301 out of the first medicine discharging nozzle 303 through the infusion tube 3031, so that medicine can be applied to nasal polyps, and because the first connecting spring 306 is arranged between the pressing block 305 and the T-shaped round platform 201, a spot-spraying effect can be realized when the medicine is applied to the nasal polyps, so that the waste of the medicine liquid can be effectively reduced.

Meanwhile, when the push rod 304 moves, the annular seat 3041 presses the gas in the gas storage cavity 3021 into the air bag plate 3025 through the first gas pipe 3023 and the second gas pipe 3024, so that the air bag plate 3025 expands, the butt rod 3027 contacts with the nasal cavity, and the nasal cavity can be slightly dilated, and thus, when the first medicine discharge nozzle 303 discharges medicine to the nasal polyp, more area of the nasal polyp can be sprayed with the medicine, and the treatment effect on the nasal polyp is improved;

after the nasal polyp is applied, the T-shaped round table 201 is rotated counterclockwise, the applying mechanism 3 is reset, when the abutting rod 3027 moves to the height of the top rod 4091, the abutting rod 3027 is just in contact with the top rod 4091, the top rod 4091 moves the abutting rod 3027 toward the T-shaped connecting block 3029, the second connecting spring 3292 is stretched, the baffle 3028 slides out of the air outlet 3026, so that the air in the air bag panel 3025 is exhausted from the air outlet 3026, and the pressure sensor at the other end of the top rod 4091 senses the pressure, so that the air suction pump 410 is activated, so that the nasal secretion adhered to the abutting rod 3027 is cleaned and collected in the suction pipe 409 under the action of the air exhausted from the air bag panel 3025 and the air suction pump, so that the nasal secretion adhered to the abutting rod 3027 does not need to be manually cleaned, and the suction pipe 409 is only required to be removed periodically in the subsequent cleaning process, the inside of the adsorption pipe 409 may be cleaned.

The parts of the invention not described in detail are prior art and are not described in detail.
