[0056] A specific application of this embodiment is as follows: When using this device, first, draw the hydrogel through the injection head of the syringe 11, store the hydrogel inside the barrel of the syringe 11, and after completion of the addition, then push out the hydrogel stored in the syringe 11 through the injection head of the syringe 11 and inject it into the part of the human body that needs treatment or filling.

When the gear 233 rotates, it drives the annular rack 234 and the rotating sleeve 222 to rotate through the gear transmission principle. When the rotating sleeve 222 rotates, it drives the ultraviolet lamp 223 to rotate, thereby adjusting the irradiation angle of the ultraviolet lamp 223, reducing the irradiation dead angle, and making the light received by each area of the hydrogel more uniform, avoiding the situation of inconsistent crosslinking degree caused by insufficient or excessive local irradiation. At the same time, loosen the bolt 123 and remove the bolt 123 from the connecting block 122, then the two protective shells 121 can be separated. After the two protective shells 121 are separated, the syringe 11 and the irradiation part 2 can be disassembled, so as to clean, maintain, and repair the syringe 11 and the irradiation part 2. When assembling the syringe 11 and the irradiation part 2, gradually close the two protective shells 121 to align the connecting blocks 122 on the two protective shells 121. Before the two protective shells 121 are closed, first pass the syringe 11 through the connecting sleeve 211 and the drive box 221, and then place the syringe 11, the connecting sleeve 211, and the drive box 221 between the two protective shells 121, so that the two convex wings on the outer wall of the syringe 11 are respectively located in the first card slots 13 on the side where the two protective shells 121 are close to each other, and at the same time, the two clamping blocks 212 on the outer wall of the connecting sleeve 211 are located in the corresponding second card slots 213.
