Particle implantation needle is a kind of treatment means?

Radioactive particle implantation therapy technology mainly relies on stereotactic system to accurately implant radioactive particles into the tumor, and emits sustained and short-distance radiation through micro radioactive sources, so that the tumor tissue suffers maximum damage, while the normal tissue suffers no damage or only minor damage. Experts believe that compared with other tumor treatment technology, radioactive particle implantation therapy technology itself is not high technology content, not big difficulty. However, since it is implanted directly into the human body and is a radioactive source, the indications should be strictly controlled.
