Abstract (English)
In Colombia and the world, there are countless accidents that cause injury to muscle bone tissue such as fractures or dislocations of limbs and joints. Generally for this type of condition, the use of casts (cast), splints and orthoses have been extended in the medical environment, to maintain the position or immobilize the parts of the body that have been affected, either temporarily or for prolonged use. , in order to support definitive medical treatment. Therefore, since Jake Evill, from the Victoria University of Wellington, New Zealand in 2013, created the splint/orthosis model called "Cortex Exoskeleton" to replace traditional splints, these have been advancing as the 3D printing technology and the mechanical properties of materials that can be used with this technology. 3D printing is currently a processing technique that has allowed complex shapes to be made by manufacturing scaffolds, orthoses, prostheses, parts of medical equipment, among others, providing significant support in the medical, engineering and industrial areas. Today orthoses and splints are widely used in the world population, being used from children to older adults after surgery, as part of medical treatment and/or rehabilitation or due to congenital problems. The cast has been the most widely used medical splint for limb immobilization in the orthopedic and rehabilitation area due to its economy, easy handling and satisfactory results. However, the use of the cast can cause problems in certain patients such as its softening and, when moistened, it could lead to the loss of strength and integrity of the cast and even the possible growth of fungi or epidermal infections. Likewise, they can be heavy for certain patients and make certain activities of the user difficult. Therefore, 3D printed limb immobilization orthoses have been replacing casts, since these can be custom made, providing greater lightness, ease of use, breathability, and impact resistance. Likewise, it prevents the accumulation of moisture, reducing the appearance of fungi and bad odours, redness or scars on the skin, thus providing greater comfort for the patient, and has shown good results in the healing of bone fractures and tissue consolidation. . In the present work, the proposed orthosis will be elaborated with the help of the Fused Wire Deposition 3D printer - FDM, which is a technology that bases its operation on a thread of material at a working temperature that moves in the horizontal XY plane. with the help of a nozzle. This thread solidifies immediately on the previous layer. It is an easy-to-use, low-cost technology that uses mechanically stable and environmentally recyclable thermoplastic polymers. 2 Likewise, they are materials capable of modeling complex geometries that could be difficult to make using other technologies or processing methods, which can become more expensive and generate by-products or compatibility problems. As a biomedical engineer, this work seeks to identify the properties that the materials used in 3D printing can offer and to highlight the advantages and possible mistakes in the design and elaboration of an orthosis prototype for its application in the area of ​​orthopedics and rehabilitation.
