technical field

The invention relates to the field of tumor treatment, in particular to a limb fixing structure and a tumor hyperthermia instrument with the structure.

Background technique

Tumor hyperthermia is a high-efficiency technical means for the treatment of tumors. Severely damaged and can die in a short period of time, so the normal tissue temperature should reach 41℃-43℃ and maintain for a certain period of time. The temperature is 3°C-7°C higher than the surrounding normal tissue, so while killing tumor cells, it will not cause damage to the normal tissue around the tumor, thus achieving no damage, no side effects, and painless treatment of tumors. Purpose.
