Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to an integrated radioactive particle protection implanter. Background Art

[0002] In traditional radioactive particle implanters, the particle short rods, particle chamber and particle chamber seat are separate structures. Before the operation, medical staff need to install the particle short rods into the particle chamber one by one, and then insert the particle chamber into the particle chamber seat. Then the particle chamber seat is connected to the puncture needle with the help of the connecting end on it, and the particle short rods are pushed into the human body along the puncture needle with the help of the push needle for tumor treatment. However, the particle short rods are radioactive and are easy to radiate medical staff during the installation process. On the other hand, due to the small size of the particle short rods, the installation operation is difficult and it is very easy to fall and lose. If they are not discovered in time, they will not only radiate the surrounding environment, but also cause disputes between the hospital and the supplier due to the lack of the number of particle short rods. Furthermore, the connection end structure on the particle chamber seat that is connected to the puncture needle is fixed and can only be adapted to one puncture needle. The hospital is limited in the choice of different manufacturers of puncture needles, resulting in some puncture needles being priced too high, and the cost of radioactive particle implantation surgery remains high.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1-6 As shown, an integrated radioactive particle protection implanter includes a particle bin 2 for storing particle short rods 1, a particle bin seat 3 with a handle 12, a push pin and a puncture needle. The particle bin seat 3 is connected to the puncture needle by means of a connecting terminal 11. The particle bin seat 3 includes an upper bin seat 31 and a lower bin seat 32. A accommodating cavity 34 for accommodating the particle bin 2 is provided between the upper bin seat 31 and the lower bin seat 32. The upper bin seat 31 is connected to the handle 12. Push holes 9 for the push pin to pass through are coaxially provided in sequence on the handle 12, the upper bin seat 31, the particle bin 2 and the lower bin seat 32. A discharge end 91 of the push hole 9 is located on the lower bin seat 32 and is connected to the connecting terminal 11. In this embodiment, a holding cavity 34 for holding a particle bin 2 with a particle short rod 1 is provided in the particle bin seat 3. During the production process, the particle short rod 1 is loaded into the particle bin 2. After the particle bin 2 is put into the holding cavity 34, the upper bin seat 31 and the lower bin seat 32 are welded and fixed to realize the integrated structure of the particle short rod 1, the particle bin 2 and the particle bin seat 3. Medical staff are not required to load the particle short rod 1 into the particle bin 2, which reduces the labor intensity of medical staff, avoids the radiation of the particle short rod 1 to the medical staff during the loading process, and reduces the disputes between the hospital and the supplier caused by the loss of the particle short rod 1 during the loading process. In this embodiment, the upper bin seat 31 and the lower bin seat 32 are both made of lead.

[0021] Since the number of radioactive particles implanted is mostly 30-40, and can reach 100-200, different numbers of particle short rods 1 can be loaded in the particle chamber 2 to make implanters of different quantities and specifications, such as 10, 20, 30, and 50 specifications, respectively. This is convenient for medical staff to select implanters of different quantities and specifications according to the actual implantation situation, so that the number of particle short rods 1 reaches the required implantation amount.

[0022] The particle bin 2 includes a bin body 5 with a spiral track 4 inside, a clockwork spring 6, a clockwork shaft 7 and a pushing component 8 arranged on the bin body 5, the two ends of the clockwork shaft 7 are respectively connected to the clockwork spring 6 and the pushing component 8, the particle short rod 1 is arranged in the spiral track 4 in sequence, the pushing component 8 is arranged adjacent to the particle short rod 1 located at the front end of the spiral track 4, the clockwork shaft 7 is driven to rotate by the tightened clockwork spring 6, the clockwork shaft 7 transmits power to the pushing component 8, and the pushing component 8 pushes the particle short rod 1 on the spiral track 4, so that the particle short rod 1 moves along the spiral track 4 and moves to the pushing hole 9 in sequence, and the particle short rod 1 can be pushed out along the pushing hole 9 by the pushing needle; the pushing hole 9 passes the end of the spiral track 4, and the particle short rod 1 cannot continue to move along the spiral track 4 after being pushed to the pushing hole 9, ensuring that the particle short rod 1 at the end of the spiral track 4 is coaxially arranged with the pushing hole 9, so that the push needle can smoothly push the particle short rod 1 out.

[0023] During operation, the connecting end 11 is installed on the discharge end 91, the puncture needle is connected to the connecting end 11, and the push needle is inserted into the push hole 9 from top to bottom, pushing the particle short rod 1 located at the push hole 9 in the spiral track 4 into the puncture needle and implanting it into the desired position along the puncture needle; after the push needle is pulled out, the clockwork spring 6 drives the clockwork shaft 7 to rotate, and the clockwork shaft 7 transfers kinetic energy to the pushing component 8, and the pushing component 8 pushes the particle short rod 1 to move along the spiral track 4. When the particle short rod 1 moves to the end of the spiral track 4, it is blocked by the warehouse body 5 and no longer moves forward. At this time, the particle short rod 1 is coaxially arranged with the push hole 9, and the push needle is inserted into the push hole 9 to push the particle short rod 1 out; until the number of particle short rods 1 reaches a preset value.

[0024] The pushing assembly 8 includes a top block 81, a power rod 82 and a push rod 83. The top block 81 is connected to the end of the clockwork shaft 7 and is located outside the warehouse body 5.

The end of the push rod 83 is located outside the warehouse body 5 and connected to the power rod 82. A spiral avoidance groove 51 matching the push rod 83 is provided on the warehouse body 5; the clockwork shaft 7 drives the top block 81 to rotate, and the top block 81 pushes the power rod 82 to rotate in the slide groove 84. The power rod 82 is connected to the push rod 83 located in the spiral track 4. During the rotation of the power rod 82, the push rod 83 drags the power rod 82 and the top block 81 to produce a relative displacement along the slide groove 84, so that the push rod 83 moves along the spiral track 4 to effectively push the particle short rod 1.

[0025] The top view of the top block 81 is rectangular or oblong. In this embodiment, the top block 81 is an oblong block. The side wall of the top block 81 contacts the side wall of the slide groove 84, and can push the power rod 82 to rotate synchronously during the rotation of the clockwork shaft 7.

The upper and lower ends of the power rod 82 located at the warehouse body 5 are respectively connected to the top block 81 on the spring shaft 7, and are respectively connected to the upper and lower ends of the push rod 83, which improves the stability of the push rod 83 and helps the push rod 83 to smoothly push the particle short rod 1 along the spiral track 4. The upper warehouse seat 31 and the lower warehouse seat 32 are respectively provided with an escape space for the power rod 82 to move.

[0027] The discharge end 91 is provided with a threaded rod, the upper end of the connecting end 11 is provided with a threaded sleeve matching the threaded rod, the lower end of the connecting end 11 is adapted to the connection part of the puncture needle, the connecting end 11 is detachably connected to the threaded rod by means of the threaded sleeve thereon, the push hole 9 passes through the threaded rod, the threaded sleeve and the puncture needle in sequence, the connecting end 11 is replaceable and installed on the lower bin seat 32, and the connection structure is simple, the disassembly and assembly are convenient, and the connecting end 11 can be replaced.
