[0001] The invention relates to the technical field of medical devices, in particular to a local thermal chemotherapy device. Background Art

[0002] Thermal chemotherapy refers to a new therapy that combines chemotherapy and heat therapy to treat tumors. Its principle is to use physical energy to heat chemotherapy drugs with good thermal effects, thereby raising the temperature of tumor tissue to an effective treatment temperature and maintaining it for a certain period of time, thereby utilizing the difference in temperature tolerance between normal tissues and tumor cells to achieve the treatment goal.

[0003] Oncological diseases tend to spread throughout the body. In terms of disease control and local isolation treatment, medicine often uses chemotherapy to control and alleviate the disease in stages. Previous chemotherapy devices were used for systemic chemotherapy of body parts.
