N2 - Loss of thumb function due to partial amputations significantly affects the usability of the hand and the quality of life of users. Effective prosthetic solutions are required to restore functionality. In this study, we present the development and evaluation of a mechanical thumb prosthesis designed for people with partial amputations, based on anthropometric proportions of an average adult between 33 and 35 years old, with movements such as flexion and extension. A simulation was performed using a load of 5 N to evaluate the safety factor in the prosthesis structure. The results show a safety range between 2.991 and 15.00, which validates the resistance and robustness of the structure to the loads applied under normal conditions of use. This advancement provides users with a tool to enhance their autonomy and well-being, thereby improving their quality of life.
