[0002] In recent years, cardiovascular and cerebrovascular diseases have become the first diseases threatening human health, and the diagnosis and treatment of cerebrovascular diseases have received increasing attention. Transfemoral whole brain angiography is a commonly used examination method for diagnosing cerebrovascular diseases. After transfemoral whole brain angiography, the patient's femoral artery puncture point needs to be pressurized to stop bleeding, and the patient's lower limbs need to be braked to avoid the patient's lower limb bending affecting the effect of compression hemostasis. However, many patients will bend their lower limbs unconsciously. In clinical practice, a restraint belt is often used to tie up the patient's operative limb. This method is simple, but not humane enough, with poor fixation effect, and patients are prone to discomfort; or a fixed brace is used to fix the patient's lower limbs. Because the lower limbs of different patients are of different lengths, the length of the existing lower limb fixation brace remains unchanged and cannot meet the needs of patients with different leg lengths.
