[0001] The utility model relates to the technical field of medical equipment, in particular to a safety mechanism and radiotherapy equipment. Background Art

[0002] Radiation therapy is a local treatment method that uses radiation to treat tumors.

[0003] However, radiotherapy uses high-energy rays to ionize and damage cell DNA, making it impossible for cells to divide and causing tumor cells to die. Although high-dose radiation can destroy cancer cells, it cannot avoid damaging healthy cells and tissues near the treatment area, causing certain side effects. For this reason, lead clothing is worn outside the human body to reduce damage. However, the lead clothing fabric is rough and heavy, and ordinary people will feel oppressive when wearing it, and the wearing comfort is not high. For this reason, we propose a safety mechanism and radiotherapy equipment. Utility Model Content
