Modelado 3D personalizado y creación de prótesis externa del dedo índice izquierdo, para un funcionamiento biomecánico eficiente

Abstract

The present tiling work had as objective to desing a customized 3D prototype of the left index finger, for an efficient biomechanical operation. The prototype was developed base don Bruno Munari´s methodology. An anthropomrtric and ergonomic analysis of the user was performed to determine the measurements of the prothesis and its subsequent modeling in Autodesk 3D Max. The solid body of the prosthesis was printed on filament Acrylonitrile Butadiene Styrene (ABS). Its mechanism of movement is made up of tensions. The aesthetic presentation of the prothesis maintains identifying features of the user as color and shape that generates a homogeneous set with the remaining fingers. The prototype may change depending on the user´s características. 3D printing allows to generate prototypes with various materials, generating different finishes that contain characteristics that the user desires, helping the patient in a psychological way for their quick recivery and acceptance of the loos. The initiative generated by the Engineer Balvina Romero of the school of Graphic Desing of the Superior Polytechnic School of Chimborazo, with its three-dimensional prototype of external prothesis for remplacement of leg and foot, with the current work of prototype research of left index finger prothesis have the commitment to improve the quality of life of people with disabilities since they are also part of the economically active population of a country. It is recommended that these types of projects have the support of compains that generate quick solutions to the user allowing their prompt inclusion in their activities.
