Individualized design and manufacturing system and method for full knee joint replacing prosthesis

Abstract

The invention relates to an individualized design and manufacturing system and an individualized design and manufacturing method for a full knee joint replacing prosthesis. Through three work stations set in different places, doctors, design personnel and engineering personnel are connected, in addition, the image processing technology, the virtual operation planning, the information communication, the individualized interaction design, the product performance fast analysis and the 3D (three-dimensional) printing manufacturing technology are merged, through the system, the doctors can know the design and manufacturing conditions of the knee joint prosthesis at any time, the design personnel can design the personnel applicable prosthesis according to the knee joint form of a patient and can modify the prosthesis design at any time according to the scheme of the doctors, finally, the engineering personnel use the 3D printing technology for manufacturing the designed prosthesis, and the individualized knee joint prosthesis best matched with the knee joint of the patient is produced, so the optimum matching between the prosthesis and the knee joint is ensured on the basis of minimum bone cutting quantity, and the effect optimization is realized. The system and the method have the advantages that the trouble that the existing prosthesis product cannot be better matched with the knee joint structure can be avoided, in addition, the individualized and customized replacing operation scheme for the patient becomes possible, and great significance is realized in the medical field.

Description

technical field [0001] The present invention relates to the field of design and 3D printing manufacturing of personalized medical implants, in particular to a personalized total knee replacement prosthesis for patients with total knee replacement based on network collaboration (osteoarthritis, rheumatoid arthritis) Design and manufacture systems and methods. Background technique [0002] Total knee replacement has been widely accepted as a very effective treatment for patients with advanced knee or osteoarthrosis. However, studies have shown that there are certain differences in the anatomical morphology of the knee joints of different races and genders. At present, knee prostheses for total knee replacement are several different types of prostheses with standardized and modular designs, regardless of the race and gender of the patient. Since the knee joint shape of each patient is different, there will be a mismatch between the prosthesis and the knee joint, which will af...
