Manufacturing of task-specific hand prosthesis using methods of reverse engineering

Proteza je pripomoček, s katerim lahko amputiranemu udu vsaj deloma povrnemo prvotno funkcionalnost. Za kvalitetno protetsko oskrbo pacienta je treba upoštevati njegove želje in zahteve ter izdelati protezo, ki jo bo pacient redno uporabljal. Pri nekaterih specifičnih opravilih, ki jih je z amputiranim udom in s standardno mehansko protezo praktično nemogoče opravljati je potrebna izdelava namenske proteze, namenjene specifičnemu opravilu ali aktivnosti. V nalogi so opisani in vrednoteni postopki ter metode izdelave aktivnosti-specifične namenske proteze gornjega uda, katere namen je brenkanje kitarskih strun, za pacienta s kongenitalno motnjo dlani. Uporabljeni postopki izdelave so vzvratno inženirstvo, CAD in 3D tisk, s katerimi bi lahko nadomestili časovno zamuden postopek izdelave standardnih protez in ležišč za protetsko oskrbo. Zasnovan končni nastavek proteze za brenkanje strun smo dinamsko vrednotili, da bi ugotovili njegovo ustreznost v dinamskem okolju, prisotnem med uporabo proteze.A prosthesis is a device that can be used to restore at least part of the original functionality of an amputated limb. In order to provide quality prosthetic care for the patient, the patient\u27s wishes and requirements must be taken into account in order to produce a prosthesis that will be used regularly by the patient. Certain particular tasks that are practically impossible to perform with an amputated limb and a standard body-powered prosthesis require the fabrication of a dedicated prosthesis for the specific task or activity. This thesis describes and evaluates the procedures and methods for the fabrication of an activity-specific, dedicated upper limb prosthesis for strumming guitar strings for patient with congenital hand disorder. The manufacturing processes used are reverse engineering, CAD and 3D printing, which could replace the time-consuming process of manufacturing standard prostheses and prosthetic sockets. The designed terminal device for string-strumming was dynamically evaluated to determine its suitability in the dynamic environment present during the use of the prosthesis
