Digitized control three-dimensional spinal orthopaedic device

A numerically-controlled (NC) 3D vertebra rectifier comprising a bed body, a head and breast plate, and a hip and leg plate;

• wherein, said bed body is of a frame structure and is divided into an upper bed body and a lower bed body;
• said bed body is installed with an automatic rising and lowering mechanism;
• said head and breast plate and said hip and lea plate are arranged along a longitudinal axis;
• said head and breast plate is installed an said upper bed body;
• a traction mechanism of said head and breast plate and an angled mechanism of said hip and leg plate is installed in said upper bed body;
• said hip and leg plate is supported by a rotary supporting arm which is positioned along the longitudinal axis;
• the lower part of said hip and leg plate is set up with a rotation mechanism about the longitudinal axis;
• and a connecting bar on said angled mechanism is connected to said rotary supporting arm of said hip and leg plate via a transverse axle, which makes said head and breast plate and said hip and leg plate as an integrity, wherein, said traction mechanism of said head and breast plate comprises two guide sliding sleeves, two longitudinal guide poles, a connecting unit, a lead screw nut, and a servo driving system;
• said two guide sliding sleeves fixed on both sides along the longitudinal axis under said head and breast plate has a sliding fit with said two longitudinal guide poles on a frame support of said upper bed body;
• said connecting unit fixed in the middle part below said head and breast plate is connected to said lead screw nut;
• and said lead screw nut fits with a ball lead screw in said servo driving system.
