Design and Construction of a Prosthetic Finger with Distal Phalanx Amputation

There is a large number of workers who have suffered an accident at work in most companies is common phalangeal and transfalangeal amputations is the case of the company Dico-Val, where a few years ago a worker suffered an accident where he lost part of the finger specifically the distal phalanx, in this way, obtaining a prosthesis in order to recover the physical capacity of workers becomes imperative; Therefore, the present research of analysis of mechanism alternatives proposes the design of a mechanically driven prosthesis of the distal phalanx of the hand using bibliographic information and analysing different types of prosthesis; comparative analysis of 3D printing materials was performed, a comparative study between design applications and laminators required for the use of 3D printing was performed, different types of prosthesis were analysed focusing on the selection of alternatives of the type of mechanism, which helps the flexion and extension movements, and the type of material for the design parameters. Finally, the results were positive as the computational verification efforts were obtained; concluding that a functional prosthesis was obtained and the selected 3D printing material (PLA) provided sufficient strength for the prosthesis to perform prehension actions.
