Description
Technical Field
The invention relates to medical clinic and medical instrument equipment, in particular to auxiliary equipment for permanently implanting iodine-125 seeds into human body for radiotherapy of tumors, which can realize automatic filling of iodine-125 seed cartridges.
Background
Radiation therapy is one of the important means for clinical treatment of tumors in medicine, and has been widely used clinically as an inter-tissue brachytherapy method along with the rapid development of accurate treatment techniques, and has become an effective means for clinical accurate treatment of malignant tumors. The seeds are adsorbed on silver rods or silver wires, and are placed on a source formed by sealing a titanium tube, and are filled into an implant gun cartridge clip and directly pushed into tumor tissues under the action of an implant needle during clinical treatment to form inter-tissue close-range accurate radiotherapy. Meanwhile, some automatic cartridge loading devices also appear, and the existing automatic cartridge loading devices have the following defects:
1. the directional ordering structure of radioactive seeds is complex: at present, the directional sorting of the seeds mainly adopts a mechanical transmission or pneumatic mode to carry out directional sorting on the seeds. The mechanical transmission mode needs a stepping motor to drive the roller orienter, and in the automatic sequencing process of the radioactive seeds, as the structural size of particles is very small and the particles need to fall into the groove along with the rotation of the roller orienter to realize orientation, the roller orienter in the orientation structure and the roller orienter mounting through hole of the hopper main body part are required to be matched with each other with high precision, and the processing and assembly difficulty of parts is high. The pneumatic mode needs a stable air source, the required air is clean inert air to blow particles into the guide groove of the particle plate, and under the action of air pressure, the radioactive particles can move along the axis of the hole in the particle plate to enter the particle outlet pipe, and the radioactive particle filling equipment designed in the two directional modes has complex structure, high filling cost and cannot be miniaturized.
2. The automatic filling structure of radioactive seeds is complex: if automatic loading of radioactive seeds is to be realized, precise butt joint of the cartridge clip and the orientation mechanism is needed, the currently adopted mode is a connecting mode of a guide rail and a sliding block, positioning is realized by using positioning beads, precise positioning of the cartridge clip is realized, and the structural design of a feed part of the cartridge clip is too complex. Secondly, the particles need to be automatically filled into the cartridge clip, the currently adopted mode is a mechanical mode, the particles are pushed into the cartridge clip by utilizing the push rod, the structure is complex, and the particles with different structural sizes also need to be filled by devices with corresponding structural sizes.
3. The filling efficiency of radioactive seeds is low: the usual grain iodine-125 (125I) sizes are: 4.5mm in length and 0.8mm in diameter. In the filling equipment for grain orientation by adopting a mechanical transmission mode, because the structural size of particles is small and the particles need to fall into the grooves along with the rotation of the roller orienter to realize orientation, the particles which do not fall into the grooves need to continuously rotate along with the roller orienter until the particles fall into the grooves to realize orientation. In the filling equipment for grain orientation by adopting a pneumatic mode, the particles are blown into the guide groove on the particle plate by using the porous air pipe through the circular arc plate, the particles which are not blown into the guide groove return to the vicinity of the porous air pipe through the inclined plate and are blown into the guide groove on the particle plate again, and the two orientation modes have randomness and have low filling efficiency.
