The spine corrector of the present invention is a medical mechanical appliance for correcting spinal curvature, which is composed of a base, a vertical lifting mechanism, a horizontal telescopic mechanism, a horizontal adjustment bar, a left and right vertical and horizontal adjustment mechanism and a pulsation correction arm. composition. The vertical lifting mechanism is fixed on the base by the flange, and the horizontal telescopic mechanism is fixedly connected to the upper end of the vertical lifting mechanism. The ends are respectively connected to the upper ends of the left and right vertical and horizontal adjustment mechanisms through the upper connector, the lower ends of the left and right vertical and horizontal adjustment mechanisms are connected to the left and right telescopic steering rods through the lower connector, and the pulsation correction arm and the left and right One end of the telescopic steering rod is connected, and the lower end of the pulsation correction arm is equipped with a correction head. The invention has the characteristics of novel structure, simple operation, remarkable curative effect, etc., and therefore belongs to a novel spine corrector integrating economy and practicability.
