[0048] Specifically, as shown in the figure, Figures 1-3 The lifting member comprises two electric push rods 5 symmetrically hingedly connected with the top end of the base frame 2, the two electric push rods 5 are both arranged in an inclined manner, and the top end of each electric push rod 5 is hingedly connected with a connecting block capable of sliding along the bottom of the supporting plate 7. When the extension rod of the electric push rod 5 is extended or retracted, the connecting block slides on the bottom surface of the supporting plate 7, so that the supporting plate 7 is inclined.

[0049] Through the above technical solution,

[0050] When the patient is subjected to the spinal correction surgery, the doctor first installs the supporting device on the operating table 1, and then adjusts the prone pad 4 to be flat through the lifting mechanism and the supporting mechanism, and then the patient lies on the prone pad 4, and then the doctor adjusts the curvature of the prone pad 4 according to the curvature of the patient's spine through the lifting mechanism and the supporting mechanism, that is, the doctor drives one end of the two supporting plates 7 to be lifted through the electric push rod 5, so that the two supporting plates 7 are inclined, at this time, the connecting block hingedly connected with the top end of the electric push rod 5 slides along the bottom of the supporting plate 7; then the prone pad 4 on the top of the supporting plate 7 is rotated between the plurality of gaskets under the action of the inclination of the supporting plate 7, so that the prone pad 4 is curved to be consistent with the curvature of the patient's spine, and finally the doctor performs the spinal correction surgery on the patient; after the surgery, the curvature of the patient's spine becomes flat, at this time, the doctor can drive one end of the supporting plate 7 to be lowered through the electric push rod 5, and then the prone pad 4 on the top of the supporting plate 7 tends to be flat, until the curvature of the patient's spine is satisfied, so as to realize the support of the patient, thereby facilitating the correction of the patient's spine.
