[0002] The development of modern medicine has gradually made it possible for humans to control and conquer cancer. In the clinical treatment of tumors, surgery, radiotherapy and chemotherapy are the three main treatment methods. Radiotherapy has a wide range of indications and is more selective. More than 70% of malignant tumor patients need to receive radiotherapy at some stage of their treatment. In order to improve the comfort of the detection bed used by patients during radiotherapy, most of them are laid with positioning pads on the radiotherapy bed to increase the comfort of radiotherapy patients.

[0003] However, the positioning pads on most existing radiotherapy beds are fixedly installed and cannot be adjusted according to people of different body shapes, which affects the comfort of patients during radiotherapy. Secondly, additional auxiliary bindings are required to fix the radiotherapy patients on the positioning pads. The operation process is cumbersome, time-consuming and labor-intensive. In response to the above problems, the inventor proposes a stable radiotherapy positioning pad to solve the above problems. Utility Model Content
