Uvod: V zadnjih časih se vedno bolj uveljavlja dejstvo, da ima športna dejavnost pozitiven vpliv na življenje invalidne osebe. Posledica tega je vedno več parašportnikov na vedno več športnih področjih. Eden izmed teh športov je paralokostrelstvo, za katerega so pogosto potrebne majhne prilagoditve za sodelovanje v vseh lokostrelskih disciplinah. A ko je okvara preobsežna, je izdelava individualno prilagojenega proteznega pripomočka edina rešitev. Namen: Namen diplomskega dela je oblikovati in izdelati tri različne funkcionalne protezne pripomočke za izvajanje paralokostrelstva za kandidata s transhumeralno amputacijo leve roke, predstaviti izdelavo teh pripomočkov in ugotoviti njihovo funkcionalnost s praktičnim preizkusom. Metode dela: Diplomsko delo temelji na praktičnem delu, ki zajema postopek izdelave različnih proteznih pripomočkov in praktični preizkus njihove funkcionalnosti. Delo smo začeli z odvzemom mer z mavčnimi povoji in s tridimenzionalnim skeniranjem modela. Na podlagi mavčnega modela smo izdelali pripomoček iz termoplasta z dodanimi pasovi in pripomoček iz pasov. Na podlagi tridimenzionalnega modela smo natisnili tretji pripomoček in ga opremili s pasovi. Rezultati: Pri prvem preizkusu proteznih pripomočkov smo ugotovili, da termoplastični pripomoček kandidatu ne ustreza, zato smo ga opustili. Pri drugih dveh pripomočkih in sprožilnem mehanizmu smo ugotovili manjše neskladnosti v dolžini pasov, ki smo jih popravili. Nato smo opravili preizkus z lokom, pri katerem se je del tridimenzionalno tiskanega pripomočka odlomil po petih strelih. Protezni pripomoček iz pasov je zdržal večjo količino strelov in se izkazal kot zelo uporaben predvsem zaradi svoje prilagodljivosti. Kandidat je po večini strelov, opravljenih sede, opravil še nekaj strelov stoje. Razprava in zaključek: Ob izdelavi za šport specifičnih proteznih pripomočkov moramo imeti v mislih tako psihofizično stanje športnika kot tudi zahteve športa. Uspešen preizkus pripomočkov in njihova primerjava z že izdelanimi pripomočki za podobne invalidnosti dokazujeta, da smo se tega držali. Navkljub uspešnosti se zavedamo, da bi bil potreben še dolgotrajen proces, preden bi prišli do končnega, popolnoma funkcionalnega proteznega pripomočka za lokostrelstvo.

• Title: Fabrication of archery prosthetic devices for a candidate with upper limb amputation : diploma work

Abstract

Introduction: Recently, the positive influence of physical activity on the life of a disabled person has been increasingly highlighted. The number of para-athletes is thus increasing in numerous fields of sport. An example of this is para-archery, which usually requires small adjustments to enable participation in all archery disciplines. However, when the disability is too severe, the fabrication of individually adjusted prosthetic devices is the only solution. Purpose: The purpose of this paper was to design and fabricate three different functional prosthetic devices to perform para-archery for a candidate with transhumeral left arm amputation, present their fabrication and determine their functionality with a practical test. Methods: This paper is based on a practical part comprising the fabrication of different prosthetic devices and a practical test of their functionality. The measurements were taken with a plaster cast and a 3D-scanning of the model was performed. Based on the plaster cast, we fabricated a thermoplastic device with added straps and a device made of straps. Based on the 3D-model, we printed the third device and added straps. Results: In the first test, we determined that the thermoplastic device did not suit the candidate, so we did not go through with it. As far as the other two devices and a trigger mechanism were concerned, we determined smaller inconsistencies in strap length, which we resolved. We then performed a test with a bow, where a part of the 3D-printed device broke off after five shots. The prosthetic device made from straps endured a greater number of shots and proved to be very useful mainly due its adjustability. The candidate shot the majority of shots while seated and some while standing. Discussion and conclusion: When fabricating sport-specific prosthetic devices, we have to consider both the psychological and physical condition of the athlete and sports requirements. A successful test of devices and their comparison with already fabricated devices for similar forms of disability proves that we took this into account. Despite the test being successful, we are aware that a lengthy process would be required to fabricate a final, completely functional prosthetic archery device.
