Abstract: This present invention relates to a digitized control three-dimensional spinal orthopaedic device for cure injured spinal. The device comprises a bed body, a head-chest plate and a breech-leg plate. The bed body has a frame configuration, and comprises a top bed body and a bottom bed body. The head-chest plate is fixed on the top bed body. A traction means of the head-chest plate and an angle means of the breech-leg plate are fixed into the top bed body. The breech-leg plate is supported by a swinging arm. A left-to-right angle means is located under the breech-leg plate. A connecting shaft of the angle means is connected to the up-to-down swinging arm by a cross rod, so the head-chest plate is integrated with the breech-leg plate. The present spinal orghopaedic device can enable the bed body to go up and down automatically, the head-chest plate can vibrate and be drawn at a high or low speed, and the breech-leg plate moves up to down, rotates left to right and vibrate.
