It is specifically designed to load iodine radioactive particles (such as iodine-125) into specific carriers, such as medical clips, for nuclear medicine treatment or nuclear medicine imaging examinations. With the increasing demand for radiotherapy, especially in cancer treatment, the need for this loading device is becoming increasingly urgent.

[0003] In the application of iodine-125 radioactive particles, the traditional loading method usually requires medical staff to manually perform one-shot-one-loading operations. Although this method is simple, it has obvious shortcomings. Each operation requires strict control of the number and position of particles. Slight errors may affect the treatment effect. More seriously, although modern medical facilities are equipped with radiation protection equipment, operators still face potential radiation risks. Especially in frequent operations, long-term exposure may have cumulative negative health effects and increase safety hazards. Summary of the Invention

[0011] Furthermore, the loading assembly includes a rack fixed to one end of the drive block and a gear meshing with it, and a drive rod is fixed inside the gear. The drive rod passes through the circular plates arranged symmetrically on the upper and lower sides. One end of the drive rod is limited to one of the circular plates, and the other end of the drive rod is provided with a second hydraulic cylinder fixed to the bottom of the second support base.

[0012] Furthermore, the shifting assembly includes a motor fixed to the second support base, and a drive plate is fixed on the output shaft of the motor, with a drive column fixed on the drive plate.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] like Figures 1-7 As shown, this embodiment of an iodine radioactive particle fully automatic magazine loading device includes a base plate 11 and a first support base 12 and a second support base 13 located thereon. The first support base 12 and the second support base 13 are provided with a fully automatic iodine ion loading mechanism. The fully automatic iodine ion loading mechanism includes a driving component 2 and a loading component 3. Under the control of the driving component 2, the loading component 3 realizes the ring arrangement of iodine ions and the picking and placing of magazines. The loading component 3 is provided with a displacement component 4. Under the drive of the displacement component 4, the loading component 3 realizes the sequential arrangement of iodine particles. The loading component 3 is provided with a magazine component 5 for rapid loading and implantation operations.

[0027] like Figures 2-3As shown, the drive assembly 2 includes a first hydraulic cylinder 21 and a first slide rail 22 connected thereto and located on the first support base 12. A drive block 23 connected to the piston rod end of the first hydraulic cylinder 21 slides on the first slide rail 22. The drive block 23 is provided with a second slide rail 24 and a third slide rail 25 arranged vertically symmetrically and laterally. A slider 26 slides on the second slide rail 24 and the third slide rail 25. A fixing rod 27 is fixed on one side of the slider 26. A fixing platform 211 and a plurality of rectangular bars 28 located on the fixing platform 211 are provided on the second support base 13. A connecting plate 29 is fixed between the rectangular bars 28 by a shaft rotation connection. The rectangular bars 28 are provided with mounting holes 210.

[0028] like Figures 4-6 As shown, the loading assembly 3 includes a rack 31 fixed to one end of the drive block 23 and a gear 32 meshing with it. A drive rod 33 is fixed inside the gear 32. The drive rod 33 passes through the circular plates 34 arranged symmetrically on the upper and lower sides. One end of the drive rod 33 is limited to one of the circular plates 34.

[0029] In use, the arranged iodine radioactive particles are sequentially placed into the placement holes 210. Then, the first hydraulic cylinder 21 is activated, driving the drive block 23 to move along the first slide rail 22. Simultaneously, the rack 31 on the drive block 23 drives the gear 32 to rotate, thereby rotating the circular plate 34 on the drive rod 33. The top of the drive rod 33 forms a [formula missing] with the circular plate 34. Figure 6 The limiting structure shown has a connecting plate 29 fixed to it on the adjacent circular plate 34. When the circular plate 34 rotates, it will drive the rectangular strips 28 on the circular plate 34 to align with the driving rod 33 as the center. Therefore, the iodine radioactive particles can be accurately placed into the magazine.

[0030] It is important to understand that as the rectangular bars 28 align with the rotation, the other end of the rectangular bar 28 pulls the slider 26 to slide along the second and third slide rails 24 and 25, facilitating automatic adjustment and ensuring smooth movement throughout the process. During movement, the rectangular bars 28 remain on the fixed platform 211, and the fixed platform 211 and the circular plate 34 maintain the same horizontal plane to allow for the normal movement of the iodine radioactive particles. Furthermore, the circular plate 34 maintains a rotatable connection with the fixed platform 211, always keeping a gap to facilitate the entry of the magazine assembly 5.

[0031] like Figures 5-6 As shown, the switching component 4 includes a motor 41 fixed on the second support base 13, and a drive plate 42 fixed on the output shaft of the motor 41. A drive column 43 is fixed on the drive plate 42. A rotating disk 44 is arranged between the circular plates 34, and the rotating disk 44 has a fitting port 45 and a drive port 46 that cooperate with the drive plate 42 and the drive column 43.

[0032] After the iodine radioactive particles are arranged in a circular pattern on the circular plate 34, the iodine radioactive particles on the placement hole 210 will pass through the hole on the circular plate 34 and enter the magazine due to their own weight. Then the motor 41 is started, and its output shaft will drive the drive plate 42 and the drive column 43 to rotate. When the drive plate 42 is in contact with the fitting port 45, the rotating disk 44 remains stationary. When the drive column 43 rotates and enters the elongated drive port 46, it will drive the rotating disk 44 to rotate.

[0033] like Figure 7 As shown, the magazine assembly 5 includes a ring 51 fixed on the rotating disk 44, and the rotating disk 44 and the ring 51 are sleeved on the drive rod 33. The ring 51 has an array of particle placement holes 52, and the particle placement holes 52 are provided with symmetrical upper and lower limiting spring plates 53. The elastic potential energy of the lower limiting spring plate 53 is greater than that of the upper one.

[0034] Iodine radioactive particles, due to their own weight, compress the upper limiting spring plate 53 and enter the particle placement hole 52 on the ring 51. Simultaneously, the lower limiting spring plate 53 supports them, ensuring the iodine radioactive particles are stably placed in the magazine. As the rotating disk 44 rotates, it drives the ring 51 to rotate, aligning the next particle placement hole 52 on the ring 51 with the hole on the circular plate 34. This automates the placement of iodine radioactive particles, reducing the workload for medical personnel. The magazine assembly 5, with its ring 51 design, can simultaneously load multiple iodine particles and, together with the rotating disk 44, can be better integrated into the implantation gun, facilitating rotation and adjustment for the sequential implantation of iodine ions into the patient.

[0035] The other end of the drive rod 33 is equipped with a second hydraulic cylinder 35 fixed to the bottom of the second support base 13. After the iodine radioactive particles on the magazine assembly 5 are loaded, the second hydraulic cylinder 35 is activated to drive the drive rod 33 downward until the drive rod 33 disengages from the ring 51 and the rotating disk 44. Then the magazine assembly 5 is taken out for use, realizing a fully automatic loading operation and reducing the safety hazard of direct contact between iodine radioactive particles and medical personnel.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
