背景技术Background Art
放射治疗是治疗癌症的主要手段之一，放射治疗治疗又分为外放射和内放射两种。外放射是利用射线通过体外照射来抑制或杀死癌细胞，具有照射面积大、易伤害周围健康组织细胞等缺点，而内放射是直接把放射性粒子植入到病灶部位，利用射线杀死或抑制癌细胞，具有靶向性强、疗效确切、无副作用、创伤小等优点，已被广大医生和患者所接受。目前，在国内内放射治疗均由医生手动植入，因此对医生的技术水平要求很高。同时粒子植入术是一种重复性工作，手术时间长，容易使医生疲劳，难以保证手术质量，因此急需一种电动粒子植入装置用来减少手术时间、提高手术质量。Radiotherapy is one of the main means of treating cancer. Radiotherapy is divided into external radiation and internal radiation. External radiation is the use of radiation to inhibit or kill cancer cells through external irradiation. It has the disadvantages of large irradiation area and easy damage to surrounding healthy tissue cells. Internal radiation is the direct implantation of radioactive particles into the lesion site, using radiation to kill or inhibit cancer cells. It has the advantages of strong targeting, definite efficacy, no side effects, and little trauma, and has been accepted by doctors and patients. At present, internal radiation therapy in China is manually implanted by doctors, so the technical level of doctors is very high. At the same time, particle implantation is a repetitive work, the operation time is long, it is easy to make doctors tired, and it is difficult to ensure the quality of the operation. Therefore, there is an urgent need for an electric particle implantation device to reduce the operation time and improve the quality of the operation.
