Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to a radioactive source loading clip assembly. Background Art

[0002] Radioactive particle implantation mainly refers to the technology of directly implanting isotope radioactive sources into the tumor area for treatment, which is a type of radiotherapy. At present, this technical means mainly uses modern imaging technology (CT, ultrasound, etc.) to place radioactive nuclides into the tumor target or around the tumor by implantation, and the radioactive nuclides continuously release radiation to kill tumor cells. The implanted particles are usually iodine 125 particles, which have a half-life of 59.6 days and a radiation radius of less than 1.7 cm in the human body. They are safe and easy to protect. The gamma rays released by the particles continue to irradiate tumor cells for 180 days, with high-dose distribution in the target tumor to kill tumor cells, while the surrounding normal tissues receive trace radiation, causing no damage or only slight damage. It is essentially a precise radiotherapy method.

[0003] The implantation process of the existing particle implantation device is generally to first puncture the tumor to the predetermined position with a puncture needle under the guidance of CT or other images, and then use a push rod to push the particles in the particle magazine to the appropriate position through the particle gun according to the preoperative TPS plan, then pull out the puncture needle to the next position, and retract the push rod to the top of the magazine, the particle magazine will automatically eject the next particle, and repeat the above operation to implant the predetermined number of particles into the tumor.

[0004] The existing particle clips need to be disassembled and manually loaded with radioactive particles during use, but the disassembly and assembly is troublesome, and the operator may suffer radiation damage during the disassembly and assembly process. There is an urgent need for a clip assembly that can be adapted for automatic loading. In addition, the storage capacity of the existing clips is small. If the clips are to be lengthened to expand the capacity, both manual and automatic loading of particles will become more difficult.

[0111] The second push rod 311226 is driven to move by a spiral spring or a torsion spring, thereby pushing the particles in the second storage slot 311237 toward the second radiation source channel 311235 .

[0112] A portion of the second push rod 311226 is embedded in the second storage groove 311237; when the second storage groove 311237 is a spiral groove and has a turning section, the end of the second push rod 311226 is provided with a flexible section that can adapt to the radial turning section to push the particles out.

[0113] When the second storage groove 311237 is a spiral groove, the working radius of the second push rod 311226 changes as it slides along the spiral groove. The change of the working radius of the second push rod 311226 is achieved by arranging the second push rod 311226 on the radial motion unit 311225. The radial motion unit 311225 is arranged in a disc shape. The radial motion unit 311225 is driven by a spiral spring or a torsion spring to achieve rotational motion.

[0114] It also includes a particle stock indicator. A second rotating shaft 311228 is rotatably arranged at the center of the second magazine body 311229. A spiral spring or a torsion spring drives the second push rod 311226 to move via the second rotating shaft 311228. The particle stock indicator indicates the particle stock in the magazine via the rotation angle of the second rotating shaft 311228.

[0115] The particle inventory indicator is connected to the second rotating shaft 311228 via a reduction transmission mechanism to achieve multi-turn counting, thereby indicating the multi-turn angle of the second rotating shaft 311228 on a dial.

[0117] The gear transmission includes a driving gear 311231 and a driven gear 311230 meshing with the driving gear 311231. The driving gear 311231 is synchronously rotated and is arranged on the second rotating shaft 311228. The driven gear 311230 is mounted on the rear cover plate 311233 through the gear shaft 311232, and the rear cover plate 311233 is mounted on the rear of the second magazine body 311229. The particle stock indicator is a pointer 311234 mounted on the gear shaft 311232 and a scale on the rear cover plate 311233.

[0118] The second cover plate 311224 is snap-fitted or screwed onto the second clip body 311229 . The second cover plate 311224 is made of a transparent material, such as lead glass, so that the number of particles in the second storage slot 311237 can be observed through the second cover plate 311224 .

[0119] Specifically, Figures 14 to 18 As shown, it includes a second clip body 311229, a second rotating shaft 311228, a first coil spring 311227, a second push rod 311226, a protrusion 311236, a radial motion unit 311225, and a second cover plate 311224. The first coil spring 311227 is assembled with a groove on one side of the inner wall of the second clip body 311229 through the groove of the second rotating shaft 311228 installed in the second clip body 311229. The radial motion unit 311225 is connected to the second rotating shaft 311228 for synchronous rotation. The second push rod 311226 is pushed to the outermost end of the inner plane thread groove of the second clip body 311229 due to the torsion of the first coil spring 311227 installed on the radial motion unit 311225. A driving gear 311231 is arranged on the second rotating shaft 311228 at the rear side of the second clip body 311229, a gear shaft 311232 and a driven gear 311230 are arranged on the second clip body 311229, and the two gears are meshed with each other. A rear cover plate 311233 is arranged on the rear side of the second clip body 311229, and a pointer 311234 is arranged on the gear shaft 311232.

[0120] The process of particle loading in this embodiment is as follows:

[0121] When particles need to be loaded, particle A312208 is inserted from the outside into the spiral groove of the second clip body 311229. When loading the second particle, the external top block passes through the first through hole 311239, and the particles in the spiral groove will be pushed and leave a filling position for the next particle. After the next particle is sent into the spiral groove of the second clip body 311229 for a certain distance, the external top block returns to the initial position. At this time, the particle can be completely pushed into the second clip body 311229. At the same time, the first coil spring 311227 on the second clip body 311229 will also drive the radial motion unit to rotate counterclockwise, and the second push rod 311226 presses the particles to continuously move toward the second radiation source channel 311235. The second cover plate 311224 made of transparent material (such as lead glass) can observe the number of particles inside the second clip body 311229. Alternatively, the number of particles can be observed by the pointer 311234 set on the gear shaft 311232 through the rotation angle of the pointer 311234; when the particles are loaded into the second magazine body 311229, the pad at the front end of the second push rod 311226 has a certain flexibility; when only the last particle is left, the pad at the front end of the second push rod 311226 will push along the end of the spiral groove to push the last particle into the second radiation source channel 311235. While the particles are being loaded, the second rotating shaft 311229 will rotate. 11228 will rotate as the number of particles increases, and the driving gear 311231 connected to the second rotating shaft 311228 will rotate to drive the driven gear 311230 to rotate. The number of teeth of the driven gear 311230 is greater than that of the driving gear 311231. When the driven gear 311230 rotates, the pointer 311234 on the gear shaft 311232 will rotate at the same time. There is a scale on the rear cover 311233. The number of particles filled can be confirmed by the position of the scale corresponding to the pointer 311234.

[0122] Example 4

[0123] A blocking sheet is provided on the side of the bottom plate located at the storage slot, and the blocking sheet covers a portion of the radioactive source in the storage slot to prevent the radioactive source from falling out. The blocking sheet is open in the middle to form a manual loading slot corresponding to the storage slot, so that the operator can use a handheld tool to clamp the radioactive source and place it down along the manual loading slot to load the radioactive source. The storage slot is provided with a compression spring accommodating slot for placing a compression spring, and the compression spring accommodating slot is provided with a detachable auxiliary rod, which prevents the radioactive source from falling into the compression spring accommodating slot during the loading process.

[0124] It also includes a mounting block, on which there is a lifting rod, which is the external driving mechanism, and on which there is a clamping mechanism for quick connection and disassembly with the bottom plate. When the mounting block moves upward and is connected to the bottom plate, the lifting rod pushes the top block upward, and the top block directly pushes the radioactive source in the radioactive source channel into the storage slot;

[0125] It also includes a base, and the mounting block can be quickly plugged into the base so that the storage slot is vertically arranged, which is convenient for the operator to manually load the radiation source. The mounting slot is provided with a locking mechanism for locking the bottom plate, and the locking mechanism adopts one or a combination of thread locking, snap locking, and lock locking.

[0126] like Figures 19 to 31 The radioactive source loading magazine comprises a third magazine body 2406001, a base 2406002 and a mounting block 2406003, wherein the mounting block 2406003 is arranged on the base 2406002, and the mounting block 2406003 and the base 2406002 are quickly plugged and installed through positioning pins, and a circular groove 2406004 for temporarily storing radioactive particles is provided on the base 2406002.

[0127] like Figure 20 to Figure 24The third magazine body 2406001 includes a third upper cover 4060011 and a third bottom plate 24060012, and the third bottom plate 24060012 is provided with a third storage slot 2406005 for storing radioactive particles, and the bottom of the third storage slot 2406005 is connected with a third radiation source channel 2406015 that crosses the third magazine body 2406001, and the third bottom plate 24060012 is installed with a baffle 2406006 (equivalent to a blocking sheet), and a square slot 2406007 (equivalent to a manual filling slot) for manually placing radioactive particles is provided in the middle of the baffle 2406006, and the width of the square slot 2406007 is smaller than the width of the third storage slot 2406005. The operator clamps the radioactive particles with tweezers, allows the long radioactive particles to pass through the square groove 2406007 in the vertical direction into the third storage groove 2406005, and then rotates the radioactive particles to place them horizontally in the third storage groove 2406005. The baffle 2406006 can block both ends of the radioactive particles to prevent the radioactive particles from falling. A compression spring accommodating groove 2406009 is provided in the third storage groove 2406005, and a semicircular empty groove 24060012 is provided on the auxiliary rod 2406008 for easy clamping with tweezers. Before manually filling the radioactive particles, the auxiliary rod 2406008 needs to be inserted into the compression spring accommodating groove 2406009. At this time, the auxiliary rod 2406008 The side surface is flush with the third storage slot 2406005 for storing radioactive particles to prevent particles from falling into the compression spring accommodating slot 2406009, and then the radioactive particles are filled with tweezers. After filling, one hand presses the stacked particles with tweezers, and the other hand pulls out the auxiliary rod 2406008. The third storage slot 2406005 is provided with a compression spring D2406010 and a third booster sheet 2406011. After filling, the compression spring D2406010 and the third booster sheet 2406011 need to be inserted, and the third booster sheet 2406011 is driven by the elasticity of the compression spring D2406010 itself to compress the radioactive source particles in the third storage slot 2406005, and the compression spring D2406010 is installed. During the installation process, a guide rod runs through the guide rod, the front end of the guide rod is threadedly connected to the third booster piece 2406011, the upper end of the third base plate 24060012 is threadedly connected to the third locking cap 2406013, and the third locking cap 2406013 is provided with a through hole 2406014 for the guide rod to pass through. The guide rod prevents the compression spring from being bent during the process of inserting the third booster piece 2406011 and locking the third locking cap 2406013. After the compression spring D2406010 and the third booster piece 2406011 are installed, at the upper end of the third base plate 24060012, the guide rod is rotated to separate the threaded connection with the third booster piece 2406011, and the guide rod is pulled out from the through hole 2406014.

The middle of the first buckle 2406018 is rotatably connected to the third locking cap 2406013 through a rotating rod 2406019. The upper end of the first buckle 2406018 is connected to the first spring 2406017. The elasticity of the first spring 2406017 itself exerts a certain thrust on the upper end of the first buckle 2406018, so that the lower end of the first buckle 2406018 is stuck on the lower edge of the third locking cap 2406013.

[0129] like Fig.21 and Fig. 27 The mounting block 2406003 is provided with a mounting groove 2406019 for inserting the lower end of the third bottom plate 24060012.

The lower end of the screw rod 2406020 is fixedly connected with a knob. The operator adjusts the length of the screw rod 2406020 extending into the mounting groove 2406019 by rotating the knob. The screw rod 2406020 pushes the top block 2406021 at the bottom of the third bottom plate 24060012 upward, so that the top block 2406021 pushes all the particles above it into the third storage groove 2406005, thereby preventing the radioactive particles placed in the third storage groove 2406005 from falling out of the third radiation source channel 2406015, which is convenient for transportation. The top block 2406021 is connected to the second spring 2406022, and the second spring 2406022 drives the top block 2406021 to reset through its own elasticity. In addition, the top block 2406021 can also be used for bottom loading of particles.

The third spring 2406025 has an outward thrust on the pressing block 2406024 through its own elasticity. A slope 2406027 is provided on the side of the third bottom plate 24060012, and a slot 2406028 is provided on the upper end of the slope 2406027. When the third base plate 24060012 is inserted into the mounting groove 2406019, the locking block 2406026 first contacts the inclined surface 2406027 and compresses the third spring 2406025 while moving along the inclined surface. When the locking block 2406026 moves to the top of the inclined surface 2406027, the locking block 2406026 is inserted into the slot 2406028 to lock the third base plate 24060012 in the mounting block 2406003. When the third base plate 24060012 needs to be taken out, it is only necessary to press the pressing block 2406024, and then take out the upper cover after moving the locking block 2406026 out of the slot 2406028.
