However, since different human bodies have weights (i.e., different weights), the existing negative plate loop pad cannot be adaptively adjusted according to different patients, so that a part of patients with heavy body weight lie on the negative plate loop pad and directly contact with a hard operating table (i.e., the deformation degree of the negative plate loop pad is insufficient to buffer the pressure generated by the patients with heavy body weight), so that the problems of muscle stiffness, blood vessel blockage, pressure sore and the like inevitably occur. Meanwhile, due to different lying postures of the human body (namely, different postures of the negative plate loop pad caused by habits of different people or different postures of the negative plate loop pad caused by different operation positions), the area of the negative plate loop pad is stressed by the human body too much, and the partial area is not stressed, so that the problem that the partial area is damaged due to the fact that the partial area is stressed too much for many times is easily caused, the service life of the product is low, and the development of the negative plate loop pad is seriously restricted.
