Fast and reliable artificial bone prosthesis manufacturing method

Abstract

The invention provides a fast and reliable artificial bone prosthesis manufacturing method which includes: using the CT or MRI scanning technology to obtain the image data of all bones of a human body under a healthy state, and a building a database of the image data; generating three-dimensional models of the bones by the bone image data in the database; performing optimization design and analysis, which includes constructions of bone cavities, bone scaffolds and bone micropore basal bodies and virtual simulation analysis such as statics analysis, kinematics analysis and kinetics analysis, on the three-dimensional models of the bones; using additive manufacturing to manufacture artificial bone prosthesis on the basis of the optimized three-dimensional models of the bones; performing bioactivity treatment on the manufactured artificial bone prosthesis; performing quality inspection on the artificial bone prosthesis after the bioactivity treatment. By the method, the artificial bone prosthesis high in reliability can be manufactured fast aiming at each patient, disability possibility of the patient is lowered, and material waste is avoided.

Description

technical field [0001] The invention relates to a preparation method of an artificial bone prosthesis, which belongs to the technical field of biomedical prosthesis. Background technique [0002] The occurrence of traffic accidents and natural disasters can easily lead to bone damage in the human body. Bone damage can cause patients to be disabled or even lose their ability to take care of themselves. Therefore, it is important to help patients with bone damage to repair defective or missing hard tissues and better restore the function of human hard tissues. A subject that the medical profession has been working hard to explore. [0003] Artificial bone prosthesis is a technology to solve and repair autogenous bone damage. Up to now, the feasibility of this technology has been confirmed, but the existing artificial bone prosthesis is mostly limited to hip joints, knee joints, teeth, femoral heads and other parts. For the preparation and replacement of positional bones, ther...

Problems solved by technology

[0003] Artificial bone prosthesis is a technology to solve and repair autogenous bone damage. Up to now, the feasibility of this technology has been confirmed, but the existing artificial bone prosthesis is mostly limited to hip joints, knee joints, teeth, femoral heads and other parts. The preparation and replacement of positional bones, there is no effective repair method for the overall damage of bones such as limbs and long bones, which results in many patients with long bone injuries being forced to choose amputation to save or prolong life

[0004] In addition, since most of the current artificial bone prostheses are mass-produced products processed by CNC machining and other subtractive manufacturing technologies (turning, pliers, milling, planing, grinding), it is impossible to quickly realize individual matching for each patient, and mass production Bone prostheses made in the United States will cause adverse reactions in some patients, and mass production cannot achieve effective resource-intensive, resulting in waste of materials
