The horizontal base 11 is composed of two horizontal rods 111 set on the left and right and two longitudinal rods 112 set on the front and back. The shape formed by the splicing is rectangular. The front and rear longitudinal rods 112 of the horizontal base 11 are fixed with oblique support frames 13, and the front and rear end oblique support frames 13 are fixed with support rods. The lower limb arc-shaped placement frame 14 that matches the shape of the human lower limbs and feet is used for placing the human lower limbs and feet. The vertical support column 12 is composed of two vertical columns 121, and the two vertical columns 121 are respectively fixed at the front left end and the front right end of the horizontal base 11. A connecting rod 122 is fixed between the two vertical columns 121. A hanger 15 for hanging on the guardrail at the end of the bed is fixed on the vertical support column 12. The hanger 15 includes two hooks 151, and the two hooks 151 are respectively inserted and fixed in the corresponding vertical columns 121.

[0012] In this embodiment, the lower limb fixation device 10 is used to place the patient's lower limbs. The lower limb fixation device 10 is hung on the bed guardrail through the hanger 15, so that the patient's lower limbs can be kept in a suitable position on the bed for simulated walking exercises.
