Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an iodine-125 particle implantation device, including an implantation component and a storage component. The implantation component includes a connecting box 1, and a catheter sheath 3 communicating with its inner cavity is installed on one side of the connecting box 1. A fixing cylinder 4 communicating with its inner cavity is installed on the other side of the connecting box 1. The fixing cylinder 4 is correspondingly arranged with the catheter sheath 3. A particle push rod 5 is slidably arranged inside the fixing cylinder 4. When using this implantation device, the particle push rod 5 can be inserted into the catheter sheath 3 from the fixing cylinder 4. A push handle 6 is fixed at the end of the particle push rod 5. Preferably, the push handle 6 has an arc-shaped structure, which makes it easy for medical personnel to push the particle push rod 5 to move. A return spring 7 is sleeved on the outside of the particle push rod 5 and located between the connecting box 1 and the push handle 6. When the medical personnel push the particle push rod 5 to move, the return spring 7 is compressed. After the medical personnel release the particle push rod 5, the return spring 7 pushes the particle push rod 5 to move and reset, so that it does not need to be pulled out of the catheter sheath 3 by personnel, which facilitates the use of this implantation device.

[0023] The connecting box 1 has an insertion port on its upper side that communicates with its inner cavity. The storage component includes a storage box 8, and the lower side of the storage box 8 has an insertion head adapted to the insertion port. Through holes are provided on both sides of the insertion head corresponding to the positions of the catheter sheath 3. A removable sealing plug 10 is installed in the through hole. The sealing plug 10 is made of, but is not limited to, plastic or rubber. The storage box 8 has a storage cavity containing several iodine particles 9. A pushing component is located in the storage cavity on the side of the storage box 8. When the storage box 8 is not in use, the sealing plug 10 seals the through hole, preventing the iodine particles 9 from passing through. The through-hole is moved to the outside to prevent the iodine particles 9 from oxidizing upon contact with external air, thus affecting their quality. When using this implantable device, the catheter sheath 3 is placed in the patient's body under external imaging guidance. The medical staff removes the sealing plug 10 from the through-hole. Then, the insertion head of the storage box 8 is inserted into the insertion port on the side of the connecting box 1. The medical staff pushes the particle push rod 5 to move. The particle push rod 5 pushes the single iodine particle in the storage box 8 out of the through-hole on the other side of the insertion head through the through-hole on one side of the insertion head and implants it into the patient's body through the catheter sheath 3. The iodine particles 9 kill tumor cells with radiation energy, facilitating the patient's treatment.

[0024] The pushing component includes a movable rod 11 that is slidably disposed on the side of the storage box 8, and a pushing plate 12 is installed at one end of the movable rod 11 and the pushing plate 12 is slidably disposed in the storage cavity. A limiting plate 13 is installed at the other end of the movable rod 11. In use, medical staff can push the movable rod 11 to move through the limiting plate 13, so that the pushing plate 12 at the end of the movable rod 11 pushes the iodine particles 9 to move in the storage cavity of the storage box 8, which facilitates the replenishment of iodine particles 9 at the through hole.

[0025] A feeding spring 14 is sleeved on the outside of the moving rod 11, and the feeding spring 14 is located between the connecting box 1 and the push plate 12. When the storage cavity of the storage box 8 contains iodine particles 9, the feeding spring 14 is in a compressed state. Each time the particle push rod 5 pushes an iodine particle 9 out of the storage cavity, the feeding spring 14 pushes the iodine particle 9 through its own elasticity, which facilitates the automatic replenishment of iodine particles 9 at the through hole and facilitates the use of this implantation device.

[0026] Both sides of the connecting box 1 are provided with holding components. The holding components include a connecting rod 15 installed on the side of the connecting box 1. A finger ring 17 is fixed to the end of the connecting rod 15 away from the connecting box 1. When using this implantation device, medical staff can insert their index and middle fingers into the two finger rings 17 respectively to hold the implantation device. Then, the particle push rod 5 can be pushed with the thumb to facilitate the use of the implantation device.

[0027] A circular plate 16 is installed at one end of the connecting rod 15 near the connecting box 1. A hinge seat is installed on the side of the connecting box 1. The circular plate 16 is rotatably installed in the hinge seat through a positioning shaft. Medical staff can rotate and adjust the position of the connecting rod 15 during use, which facilitates the use of the connecting rod 15.

[0028] A positioning cylinder 2 is fixed on the side of the connecting box 1 near the catheter sheath 3. The catheter sheath 3 is detachably installed in the positioning cylinder 2. Medical staff can select an appropriate length of catheter sheath 3 according to the iodine particle implantation depth to facilitate the implantation of iodine particles 9.

[0029] A magnet 18 is installed on the side of the connecting box 1 near the insertion port. A magnetic suction component 19 is installed on the side of the storage box 8 at the position corresponding to the magnet 18. The magnetic suction component 19 includes, but is not limited to, a neodymium magnet or an iron sheet. After the insertion head at the end of the storage box 8 is inserted into the insertion port on the side of the connecting box 1, the magnet 18 attracts the magnetic suction component 19 to position the storage box 8, which facilitates the installation and use of the storage box 8.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
