    Desarrollo de prototipo de prótesis ajustable multiusuario de miembro superior
    (Universidad EAFIT, 2024) Chávez Castaño , Juan Camilo; Guarín Grisales, Álvaro de Jesús
    The World Health Organization estimates that around 1.3 billion people in the world live with disabilities, and in Colombia it is estimated that there are 1,298,738 people with disabilities, 18.5% of them affected in the upper limbs. Amputation in this area negatively impacts the patient's independence, functionality, and emotional state. To address this problem, a study was carried out based on a projective methodological cycle to design an adjustable and universal prosthesis for cases of amputation of the middle third of the forearm or the entire hand. During the research, a prosthesis prototype was created that was easy to fit and suitable for daily activities, with a comfortable and secure fit between the socket and the residual stump. However, the need to soften the coupling between the terminal device and the prosthesis was identified due to difficulties in its manipulation. Damage to the ratchet guide was observed and the need for adjustments to the suspension device was detected for users with greater muscle mass in the biceps. The simulations showed that the socket is safe, but the terminal device requires redesign due to evident structural flaws
