[0020] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1 As shown, the drug delivery device for anorectal department proposed by the present invention includes a treatment part 1 and a control part 3. The treatment part 1 is connected to the control part 3 through a telescopic motion part 2. The control part 3 drives the telescopic motion part 2 to extend and retract. The treatment part 1 moves back and forth driven by the telescopic motion part 2.

[0022] A drug injection head 11 is arranged at the top of the treatment part 1. The interior of the drug injection head 11 is a cavity structure. A plurality of injection holes (not shown in the figure) are evenly arranged on the surface of the drug injection head 11. The drug injection head 11 is rotatably connected to the connection pump 13 through a rotating shaft 12. A drug channel 122 is arranged inside the rotating shaft 12. An electric control valve 121 is arranged at the connection between the drug channel 122 and the internal cavity of the drug injection head 11. The drug channel 122 is connected to the connection pump 13 through a pipeline. An infrared sensor 14 and a millimeter wave sensor 15 are symmetrically arranged at one end of the rotating shaft 12 near the drug injection head 11. The infrared sensor 13 and the millimeter wave sensor 14 are used to detect the location of the lesion and whether the drug is sprayed evenly. A rotating ring gear 16 is arranged around the end of the rotating shaft 12. The output shaft of the micro motor 18 is connected to the rotating gear 17. The rotating gear 17 is meshed with the rotating ring gear 16. Under the drive of the micro motor 18, the rotating gear 17 can drive the rotating ring gear 16 to rotate, thereby driving the rotating shaft 12 to rotate. The tail of the treatment part 1 is provided with a liquid storage container 4, which stores liquid medicine and is connected to the connection pump 13 through a pipeline. The shell of the treatment part 1 is made of polycarbonate material, which has good infrared penetration and good wave transmission. The working process of the treatment part is:

[0023] S1. The rotating shaft 12 drives the infrared sensor 14 and the millimeter wave sensor 15 to perform rotation detection, and the detection data is wirelessly transmitted to the control unit 3.

[0024] S2. The control unit 3 determines whether there is a lesion at the current position by analyzing the detection data. If so, it goes to S3. Otherwise, it controls the telescopic motion unit 2 to move forward a set distance and returns to S1.

[0025] S3, the infrared sensor 14 and the millimeter wave sensor 15 stop working, and the telescopic motion part 2 is controlled to retract backward by a set distance, so that the medicine injection head 11 faces the lesion.

[0026] S4, the rotating shaft 12 drives the medicine ejection head 11 to rotate clockwise for a set time to eject medicine.

[0027] S5, control the telescopic motion part 2 to move forward a set distance so that the infrared sensor 14 and the millimeter wave sensor 15 face the lesion, and the rotating shaft 12 drives the infrared sensor 14 and the millimeter wave sensor 15 to perform rotation detection, and the detection data is wirelessly transmitted to the control part 3.

[0028] S6. The control unit 3 determines whether the drug distribution is uniform by analyzing the detection data. If it is uniform, the telescopic motion unit 2 is controlled to advance forward a set distance and return to S1. Otherwise, the telescopic motion unit 2 is controlled to retract backward a set distance so that the drug injection head 11 faces the lesion. The rotating shaft 12 drives the drug injection head 11 to rotate counterclockwise for a set time to inject the drug. The telescopic motion unit 2 is controlled to advance forward a set distance so that the infrared sensor 14 and the millimeter wave sensor 15 face the lesion. The telescopic motion unit 2 is then controlled to advance forward a set distance and return to S1.

[0029] An annular fixed end 5 is provided at the end of the telescopic motion part 2, and a fixed airbag 6 is provided on the outside of the annular fixed end 5. The annular fixed end 5 and the fixed airbag 6 cooperate with each other to fix the treatment part 1 and the telescopic motion part 2 inside the anorectal cavity. An air pressure sensor 52 is provided at the end of the annular fixed end 5 facing the treatment part 1, and a ventilation pipe 51 is provided inside the annular fixed end 5, and an electric control valve (not shown in the figure) is provided inside the ventilation pipe 51. A pressure sensor 61 is provided on the surface of the fixed airbag 6, and the inflation and deflation of the fixed airbag 6 are controlled by means of a micro air pump provided inside the control part 3. When the annular fixed end 5 is located inside the anorectal cavity, the fixed airbag 6 is inflated until the data of the pressure sensor 61 reaches the pressure threshold to block the anus, and the air pressure sensor 52 detects the air pressure inside the anorectal cavity. When the air pressure exceeds the air pressure threshold, the electric control valve in the ventilation pipe 51 is opened to release the pressure until the air pressure is less than the air pressure threshold.
