Abstract

The invention provides a personalized adjustable osteotomy guide plate. The personalized adjustable osteotomy guide plate comprises a guide plate body and a positioning base connected with the guide plate body, an osteotomy groove is formed in the guide plate body, and a swing saw can perform osteotomy operation through the osteotomy groove. The personalized adjustable osteotomy guide plate has the advantages that the prosthesis implantation after osteotomy conforms to a knee joint force line, the service life of a prosthesis is prolonged, the structure is simple, the cost is low, and the personalized adjustable osteotomy guide plate is suitable for popularization.

Description

Technical field [0001] The present invention relates to the technical field of junction apparatus, and in particular, a personalized adjustable junction guide. Background technique [0002] Traditional total knee joint replacement is permed by a mechanical orientation, and the marrow is positioned, and the surgeon positions anatomical sign, the lower limb line and the prosthesis axis of the anatomy, the lower extremity line and the prosthesis. Although people continue to improve, the mechanical operation is simplified to achieve higher precision, enabling the prosthesis to inform the joint line and improve the prosthesis life. [0003] However, in the prior art, the mechanical structure is complex, high cost, and the width of the slot can be easily changed, and there is no limit to the zigzifer, and there is also an unable to realize the movement in the direction of the force line to carry out the bone position. Defects such as adjustment. Inventive content [0004] The present ...
