Abstract (Croatian)

Cilj diplomskog rada je razvoj djelomične proteze šake prilagodljive različitim stanjima amputacije i antropomjerama korisnika. Na tržištu su ovakva rješenja slabo zastupljena, zbog čega su korisnici s djelomičnom amputacijom šake u lošem položaju pri izboru protetičkog pomagala. Razvoj proteze velikim je dijelom zasnovan na međunarodnim normama, recenziranom i objavljenom znanstvenom radu iz različitih područja (anatomije, antropometrije, biomehanike, protetike). U razvoju su korištene i spoznaje o karakteristikama sličnih trenutno dostupnih proizvoda. Najveći uočeni problem je neusklađenost korisničkih potreba i tehničkih karakteristika proteza, a za rješavanje tog problema razvijen je novi pristup dimenzioniranju i izradi proteze. Rezultat rada je matematički model za određivanje dimenzija svake komponente proteze, te sustav prilagodbe proteze individualnom stanju amputacije. Na temelju tih modela izrađeni su parametarski računalni modeli protetičkg prsta i protetičkog palca. Uz model je priložen i detaljan opis radnog principa svake komponente i proteze kao sklopa. Ekonomična izrada ovakvih proteza omogućena je primjenom aditivnih proizvodnih tehnologija. Proteza s jedne strane predstavlja trenutne mogućnosti tehničkih sustava, a s druge uzor za razvoj novih protetičkih pomagala.

Abstract

The goal of the graduate thesis was development of a partial hand prosthesis adaptable to various amputation levels and user anthropomeasures. In the market, such solutions are poorly represented, which is why users with partial hand amputations are in an unfavorable position. The development of prostheses is largely based on international norms, reviewed and published scientific work from several areas (anatomy, anthropometry, biomechanics, prosthetics). Understanding of charactheristics of similar products were also used. The biggest problem encountered is the lack of compatibility between user needs and technical features of the prosthesis, and to address this problem, a new approach to dimensioning and prosthesis manufacturing has been developed. The result of the work is a mathematical model for determining the dimensions of each component of the prosthesis, and the adjustment procedure for individual usres’ needs Based on these models, parametric computer models of prosthetic finger and prosthetic thumb were made. A detailed description of work principles of each component and prosthesis as an assembly is provided along the model. Economical production of such prostheses is enabled by the use of additive manufacturing technologies. The prosthesis on the one hand represents the current possibilities of technical systems, and on the other model for the development of new prosthetic aids.
