Design protézy horní končetiny po částečné amputaci prstů s nastavitelným úchopem

Abstract

This bachelor thesis focuses on the design and realization of a prosthetic hand intended for patients after partial finger amputation (excluding the thumb). The goal was to create a functional, modular, and aesthetically pleasing prosthesis with an adjustable grip, using 3D printing technology. The thesis includes a review of current types of upper limb prostheses, 3D printing technologies, and an analysis of existing solutions. The design is based on a 3D scan of the hand and incorporates the BOA system, which allows easy activation of finger grip via a rotary dial. The final model was created in Rhinoceros 8 software and printed using MJF technology from PA11 and TPU materials. The thesis includes weight calculations and comparisons with other available prostheses. The resulting design meets the requirements for functionality, ergonomics, and low weight, and is intended for users with various configurations of partial finger amputations (excluding the thumb).
