Device and method for filling radioactive particle magazine

Abstract

The invention relates to a device and a method for filling a radioactive particle magazine. The device comprises a vibration system used for supplying radioactive particles, an escapement system arranged on a sliding rail system, an assembly table used for fixing a particle bin assembly of the radioactive particle magazine, and a control system. The method specifically comprises the steps that under the control of the control system, the escapement system sucks radioactive particles from the vibration system in sequence through cooperation of the sliding rail system, and the sucked radioactiveparticles are transferred to the position above the assembly table and loaded into the particle bin assembly of the radioactive particle magazine. The can automatically complete radioactive particlemagazine filling, is high in production efficiency, can accurately adjust the negative pressure through negative pressure suction during filling, cannot damage radioactive particles, can greatly reduce the error rate, effectively reduces the labor intensity of operators and ionizing radiation borne by the operators, and is beneficial to labor protection.

Description

technical field [0001] The invention belongs to the technical field of application of medical radioactive particles, in particular to a device and method for filling a radioactive particle magazine. Background technique [0002] Malignant tumors have always been a major disease that threatens human health. Implanting radioactive particles into tumor tissue for brachytherapy is a new technology for tumor treatment developed in recent decades. When the radionuclide in the radioactive particles decays, it emits rays, and continuously irradiates the tumor cells at close range, kills the tumor cells, makes the tumor cells lose their ability to reproduce, and achieves the purpose of alleviating and treating the disease. This technology has been widely used in the treatment of various tumors, such as prostate cancer, breast cancer, liver cancer, ovarian cancer, brain tumor, orbital tumor, etc., and has achieved good therapeutic effects. Clinical practice has proved that this techno...

Problems solved by technology

The radioactive particles are small in size and radioactive. The manual method used to load the radioactive particle magazine is inconvenient and inefficient. Because the shell wall of the radioactive particles is very thin, it is easy to crush the shell when picking up the radioactive particles with tweezers, leaving dents, and the labor intensity of the operator is high (especially the eyes are prone to fatigue), the radiation dose received is high (especially the radiation dose received by the hands is high), and in addition, errors are prone to errors during the manual operation ( Such as: the number of loaded radioactive particles is inconsistent with the predetermined), therefore, based on the above technical problems, this patent designs a device for loading radioactive particle magazines and a method for loading radioactive particle magazines with the device
