Abstract

The invention discloses a multi-needle automatic puncture device for radioactive particle implantation treatment of a tumor, comprising a mobile positioning module (100), a dual-arm lifting module (200), a template positioning module (300) and an automatic puncture module (400), wherein the top of the mobile positioning module (100) is connected with the lower part of the dual-arm lifting module (200), and the top of the dual-arm lifting module (200) is provided with the template positioning module (300) and the automatic puncture module (400). The multi-needle automatic puncture device for radioactive particle implantation treatment of the tumor disclosed by the invention can accurately and reliably implant radioactive particles at a designated position of a patient body, thereby achieving the purpose of precise radiotherapy, and has great practical significance of production.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-needle automatic puncture device for tumor radioactive particle implantation treatment. Background technique [0002] At present, brachytherapy is an important method in the treatment of malignant tumors. It is a method to treat patients with cancer by implanting radionuclides in the body and using the biological effects of soft X-rays produced by their decay. Compared with external radiation therapy, it has many advantages: First, it has a very high dose distribution ratio between tumor and normal tissue, and it has great lethality to cancer cells near the source, while the dose distribution to normal tissue drops sharply, thus avoiding The disadvantages of excessive damage to normal tissues by external irradiation; second, the shortening of treatment time reduces the proliferation of tumor cells; third, due to the lower dose rate, the dependence on oxygen is red...
