Abstract
The utility model relates to the filed of human bone substitutes, in particular to a novel carbon fiber artificial bone. The novel carbon fiber artificial bone is characterized in that a middle layer structure of the artificial bone adopts high-strength carbon fibers, so that the hardness and the toughness are strengthened; the carbon fibers are immersed with phenolic resin to form composite reinforcing materials, namely unidirectional continuous fibers; a gasified silicon carbide layer is formed on the outer layers of the carbon fibers to form a novel composite body; and epoxy resin is stuck on the silicon carbide outer layer in the carbon fiber drawing direction so as to form an epoxy resin layer, the outer layer of the epoxy resin layer is subjected to plasma spraying with HA (hydroxyapatite) so as to form an HA layer, and the outer layer of the HA layer is provided with an OPG (osteoprotegerin) protein layer. The novel carbon fiber artificial bone provided by the utility model has the characteristics of high strength, good hardness, good toughness, corrosion resistance, high bearing capability, good histocompatibility, good firmness and durability, no toxicity, no irritation, good molding performance and reasonable price.
Description
Technical fieldThis utility model relates to people's bone substitute field, specifically relates to a kind of novel carbon fiber artificial bone.
Background technologyThis utility model relates to people's bone substitute field.In daily routines, damaged very common because of the bone that reasons such as wound, infection, tumor and congenital diseases cause, treatment that bone is damaged and reparation are one of clinical common difficult diseases of orthopaedics.Existing repair materials has from body bone, allograph bone and artificial bone succedaneum; Take inconvenience from the existence of body bone; Transplant limited problem, allograph bone exists organizes incompatibility, the problem of rejection; The artificial bone succedaneum is having higher requirements aspect toughness, holding capacity, plasticity, the histocompatibility, and the artificial bone succedaneum can not satisfy the needs of clinical practice in the prior art.
At present, adopt hydroxyapatite (HA) materials as repairing bone defect both at home and abroad, the in-vivo embed evidence more; Hydroxyapatite can promote the chemical bond of bone effectively; Have the good tissue compatibility, can accelerate the growth of new bone,, nonirritant nontoxic body; Be difficult for wearing out, be prone to and plasticity.But aspect mechanical property, still can not satisfy application need, be 15 * 10 like the thermal coefficient of expansion of HA
-6K
-1, than titanium alloy 8.8 * 10
-6K
-1Wait other metal a lot of greatly, and the intensity of HA and toughness are relatively poor, and also relatively poor with the adhesion of matrix.
Summary of the inventionIn view of the defective that prior art exists, the purpose of this utility model is to provide a kind of intensity high, good hardness, good toughness; Corrosion-resistant, bearing capacity is high, and histocompatibility is good, and is durable; Nontoxic, nonirritant, plasticity is good, the novel carbon fiber artificial bone of reasonable price.
Carbon fiber is the excellent new material of a kind of mechanical property, and its proportion is less than 1/4 of steel, and carbon fiber resin composite material tensile strength all more than 3500Mpa, is 7～9 times of steel generally, and tensile modulus of elasticity is that 230～430Gpa also is higher than steel.Carbon fiber not only has the intrinsic intrinsic property of material with carbon element, has the soft machinability of textile fabric again concurrently, is fortifying fibre of new generation.This utility model is to adopt high-strength carbon fiber, and carbon fiber is unidirectional array, with after the resin impregnated of trace as renovation reinforced reinforcement material; Improved the tensile strength of original carbon fiber, have in light weight, high resiliency; High strength, high-durability, corrosion resistant characteristics.
For realizing above-mentioned purpose, the technical solution that this utility model adopted is that the artificial bone interlayer structure adopts high-strength carbon fiber, and for adding strong hardness and toughness, carbon fiber becomes composite reinforcing material with the phenolic resins preimpregnation, is unidirectional continuous fiber; Resin can be high temperature resistant, anti-oxidation, and be insulant; The outer gas phase sedimentation method that adopts of carbon fiber; Through heat, chlorosilane and high-purity hydrogen are reacted, chlorosilane is cracked into hydrogen chloride and carborundum; Carborundum is deposited on carbon fiber surface and forms silicon carbide layer, a kind of novel complex; Epoxy resin sticks on the carborundum skin along the carbon fiber draw direction, forms epoxy resin layer, and the outer plasma spraying HA of epoxy resin layer forms the HA layer; HA layer skin is provided with the OPG albumin layer, and independent OPG albumen is prone to lose with body fluid flow, can't play one's part to the full, and there being the internal layer carrier to process under the situation of complex, can play one's part to the full.
Paste before the carbon fibre material, the carbon fiber of the carborundum that need will gasify was placed 8～12 hours, and the room temperature cool drying makes temperature remain on more than-10 ℃ relative humidity RH＞80% in the taping process; During stickup, try not to leave air, behind the stickup cold coating, need natural curing reach initial cure in 1～2 hour, setting up period is avoided external interference and collision.
Since the utlity model has the intensity height, good hardness, good toughness, corrosion-resistant; Bearing capacity is high, and histocompatibility is good, and is durable; Nontoxic, nonirritant, plasticity is good, the characteristics of reasonable price; Can carry out the production of mass, adaptable across clinical needs, be a kind of new product with promotional value.
Description of drawings
Fig. 1 is that this utility model structure is cutd open layer figure.
Reference numeral shown in Figure 1 is following: 1, carbon fiber, 2, phenolic resins, 3, carborundum, 4, epoxy resin, 5, HA, 6, OPG albumen.
The specific embodiment
This utility model combines 1 pair of structure of accompanying drawing to describe, and concrete scheme is: interlayer structure adopts high- strength carbon fiber 1, and 2 preimpregnation of carbon fiber 1 usefulness phenolic resins become composite reinforcing material, are unidirectional continuous fiber; 3 layers of the outer gasification of carbon fiber 1 carborundums, a kind of novel complex; Epoxy resin 4 sticks on carborundum 3 skins along carbon fiber 1 draw direction, forms 4 layers of epoxy resin, and 4 layers of outer plasma spraying HA5 of epoxy resin form the HA5 layer; HA5 layer skin is provided with 6 layers in OPG albumen.
Paste before the carbon fibre material, the carbon fiber of the carborundum that need will gasify was placed 8～12 hours, and the room temperature cool drying makes temperature remain on more than-10 ℃ relative humidity RH＞80% in the taping process; During stickup, try not to leave air, behind the stickup cold coating, need natural curing reach initial cure in 1～2 hour, setting up period is avoided external interference and collision.
In manufacture process,, note safety utilization of electric power because of carbon fiber is a conductive material; Should avoid the horizontal bending and the distortion of carbon fiber, otherwise easy of crack is destroyed; The resin raw material of pasting usefulness needs sealed storage, keeps fire away, and avoids the sunlight direct irradiation.
