PEEK Carbon Fiber Bone External Fixator bracket
Product Details
The fixation of clinical fractures mainly involves internal fixation, external fixation and external fixation. | |
 The internal fixation is to restore and fix the fractures with steel plates and screws under direct vision. The external fixation is made by traditional plaster and splint. The fracture site is locally externally fixed to maintain stability, and the external fixator uses a fixed stent to drive a special steel nail into the bone to achieve stability. |
 The raw materials used to make the external fixator not only meet the basic functions of fixation, drafting, and pressurization, but also contribute to the repair of the fracture. The configuration, volume, weight and flexibility are also important. Generally, the raw material with good fixation can achieve the healing of the original bone, but the stress shielding phenomenon is not conducive to the formation of the external epiphysis. The fracture healing often needs to last for a long time, and it is prone to secondary fracture, so the external fixator is in the material. High-quality materials with good strength, light weight and X-ray transmission must be used. |
Comparison of traditional with PEEK carbon fiber Bone External Fixator bracket
 Traditional bone external fixators Traditional bone external fixators are mostly made of metal materials, such as titanium alloy, cobalt chromium molybdenum alloy, etc. The elastic modulus is more than 100 GPa, but the human bone elastic modulus is generally only 1-3 GPa, and the excessively high elastic modulus is inevitable. Severe stress occlusion is created, so a composite material that is slightly high and has a good modulus of elasticity is relatively more suitable. The use of long carbon fiber reinforced PEEK composite material instead of the general chopped or powder carbon fiber reinforced composite material to make the external fastener parts has more outstanding application value in terms of wear resistance. |  PEEK Carbon Fiber Bone External Fixator bracket Polyetheretherketone (PEEK) has low density, good processing performance, hydrolysis resistance, corrosion resistance, flame retardancy and insulation. PEEK resin is non-toxic and light in weight, and is the closest material to human bones. The combination of the body, but its toughness and impact strength deviation, when combined with the reinforcing fiber carbon fiber, its mechanical properties will be significantly increased, the wear rate and friction coefficient of the material will also be reduced, in addition, the performance of the composite material can be designed The property can also satisfy a variety of stiffness requirements in a wide range, and generally exhibits good thermal stability, corrosion resistance, light weight, good electromagnetic radiation, and good interface between PEEK and carbon fiber, carbon fiber. The reinforced PEEK composites excel in creep resistance, heat and humidity resistance, aging resistance and impact resistance. |
