Each adjusting cylinder 143, support rod 142 and support seat 141 together form a stable triangular structure, which can provide sufficient support force to each corner end of the bed plate 2 and effectively support and reinforce the bed plate 2. Through such design, the bed surface collapse or deformation during the operation is greatly avoided, the patient's body discomfort caused by the unstable bed surface is prevented, and the possible serious medical accidents are effectively avoided.

[0053] When the patient is positioned, the height of the patient is first determined, and the silicone baffle 24 is fixedly installed on the side surface of the head section 23 and the foot section pad 21 of the bed plate 2. The silicone baffle 24 is used to limit the patient's feet and head.
