In recent years, carbon fiber composites have been used in many fields such as aerospace, public transportation, industrial production, and also medical devices. Today we are going to talk about the advantages of carbon fiber composites for medical devices. First of all, we would like to mention an important medical apparatus in orthopedic surgery - bone external fixation brace. External bone fixation brace has the function of replacing, repairing or strengthening tissues and organs, it can not only fix the fractured bone, but also can be used to correct some bone deformities. Compared with the traditional treatment and internal fixation, the external bone brace has the advantages of easy operation, small surgical incision, reliable fixation, easy adjustment and easy local wound cleaning, so it has become a more popular treatment method in clinical practice.The following is a specific description of the characteristics of the carbon fiber bone external fixation scaffold .
Biocompatibility and Safety of Carbon Fiber Bone Fixation Scaffold
The ideal material for bone external fixation scaffold must have good biocompatibility, including non-toxic, non-irritating, conducive to seed cell adhesion, proliferation, degradation products, and no harmful effects on the body, therefore, the material of bone external fixation scaffold is directly related to the clinical application safety of the final product. The evaluation requirements according to the experimental studies include the use of cytotoxicity test to determine whether the material extracts cause cell lysis, growth inhibition and other effects on cells, the use of delayed hypersensitivity test to evaluate whether the material extracts are potentially contact allergic, the use of intradermal irritation test to evaluate whether the tissue reacts to the material extracts with local irritation, and the use of acute systemic toxicity test to evaluate whether the material extracts have local irritation in animal models. The study showed that the carbon fiber bone fixation scaffold had no cytotoxicity or acute systemic toxicity, no delayed sensitization in guinea pigs, and no skin irritation. This shows that the carbon fiber bone external fixation scaffold has good biocompatibility and the safety of the application of carbon fiber bone external fixation scaffold has been guaranteed.
X-ray permeability of carbon fiber bone fixation scaffold
Carbon fiber bone external fixation brackets and other materials such as aluminum alloy and stainless steel brackets have the advantages of high strength and fatigue resistance, which can provide immediate stabilization of the fracture site, and also show more ideal biocompatibility in clinical applications. However, in practice, carbon fiber brackets are lighter than aluminum and stainless steel brackets and have better elastic modulus, corrosion resistance, and especially X-ray transmissibility. The X-ray transmittance of carbon fiber composite material is only less than 1.0 mmAL of aluminum equivalent, which can help X-ray penetrate the body accurately and unerringly, and also present a high definition pattern on the screen after multiple conversions of the equipment, which is of great significance in the treatment process of fracture patients. Therefore, its excellent X-ray transmission also makes it stand out among various materials of bone external fixation brackets, and it has become a typical example of carbon fiber application in medical devices, which has contributed to the improvement of medical standards, and at the same time, more carbon fiber composites have been tried to be used in various medical devices.
