In addition to traditional brain surgery, radiation therapy methods such as gamma knife, CyberKnife, and proton knife are also constantly providing patients with better treatment options. Although radiation therapy eliminates the risk of craniotomy in surgical operations, however, the patient's limbs need to be accurately limited during radiation therapy to achieve a more effective treatment effect. Although the current limiting device can fix the patient with a certain intensity, the limiting method and limiting strength of the current general limiting device cannot be applied to all patients.
