Abstract
The invention discloses a carbon-carbon composite material artificial skeleton, and relates to the technical field of medical supplies. The invention is applied to the field of artificial bone materials in human bodies or animal bodies, and comprises a carbon fiber preform, pyrolytic graphite or pyrolytic carbon and a surface coating; the surface coating adopts one of a hydroxyapatite layer, a pearl layer and high-strength mineralized hydrogel, and the surface coating method comprises dipping, in-situ growth or spraying; filling pyrolytic graphite or pyrolytic carbon by vapor deposition or impregnation sintering process; the manufacturing process comprises the following steps: manufacturing a carbon fiber preform, filling and densifying, forming a blank by precision machining, and obtaining the artificial skeleton by a surface coating mode. Compared with stainless steel and titanium alloy metals, the invention has the advantages of lighter weight and lower density, the specific density can be designed according to different parts, the requirements of the structure density and the strength of different parts are met, the invention has good biocompatibility, anisotropy and strength can be designed according to actual prefabricated bodies.
Description
Technical Field
The invention belongs to the technical field of medical supplies, and particularly relates to a carbon-carbon composite artificial skeleton.
Background
Artificial bone is a new inorganic metallic material with biological function, which is similar to the structure of human bone and natural tooth. The traditional orthopedic surgery usually adopts metal materials, fixtures including titanium alloy, stainless steel and the like are used for bone setting, resetting, fixing, repairing and the like, the fixtures in the metal are continuously remained in a patient body after wound healing, the strength is not changed, stress shielding is easily generated in the bone healing process, the growth of new bones is not facilitated, the risk of fracture possibly occurring again after fracture healing is caused, most of the fixtures in the metal need secondary surgery for dismantling after wound healing, the pain of the patient is increased, and the treatment cost of the patient is increased.
The carbon/carbon composite material has good biocompatibility and mechanical compatibility, solves the problems of strength and toughness of the carbon material, is a novel biomedical material with great potential, has great application prospect in the field of bone repair and bone replacement, but because the shape of the artificial bone is complicated, carbon/carbon parts with complicated shapes are difficult to prepare by adopting the traditional carbon/carbon composite material preparation methods such as chemical vapor infiltration or liquid phase impregnation, the preparation period is long, the cost is high, on the premise of ensuring the performance, the artificial skeleton with a complex shape is prepared in a short time, which is a problem to be solved urgently when the artificial skeleton made of the carbon/carbon composite material can be developed and applied, a product prototype and a corresponding mould can be quickly manufactured by a quick prototype manufacturing technology, and the production development period of the product is shortened; according to the technical scheme, the carbon fiber preforms are adopted, and pyrolytic graphite or pyrolytic carbon and a surface coating are filled between the carbon fiber preforms, and the surface coating is attached in a dipping, in-situ growth or spraying mode, so that the strength and density actually required by human bones are met, and the problems are well solved.
Disclosure of Invention
