20.500.12556/RUL-190085 Razvoj metod pritrjevanja aktuatorjev za eksperimentalno analizo deformacij človeške medenice Development of methods for actuator attachment to the human pelvis for deformation analysis in experimental biomechanical testing Pri eksperimentalnih biomehanskih raziskavah na medenici je za simulacijo delovanja mišic potreben zanesljiv način pritrditve elementov na kost, ki omogoča prenos obremenitev brez mehanskega posega v njeno strukturo. Namen magistrskega dela je bil raziskati možnost uporabe lepil za takšen način pritrjevanja ter določiti najprimernejše lepilo za nadaljnje eksperimentalne raziskave na medenici. Za izvedbo preizkusov smo zasnovali in izdelali posebno preizkuševališče ter pripravili kostne vzorce in pripadajoče preizkušance. Eksperimentalno smo primerjali štiri izbrana lepila: medicinski lepili Histoacryl in Dermabond ter tehnični lepili Loctite 435 in Loctite EA 9466. Mehansko nosilnost lepljenih spojev smo določili z nateznimi preizkusi, pri katerih smo spremljali silo do porušitve posameznega spoja. Najvišjo povprečno maksimalno napetost je doseglo lepilo Loctite EA 9466 (376 N/cm²), sledili pa so Loctite 435 (248 N/cm²), Dermabond (176 N/cm²) in Histoacryl (103 N/cm²). Rezultati so pokazali tudi vpliv priprave kostne površine in kakovosti naleganja preizkušancev na nosilnost ter ponovljivost lepljenih spojev. Nosilnost spoja, dosežena z lepilom Loctite EA 9466, je bila primerljivega velikostnega reda kot izvlečna sila neojačanega 3,5 mm kortikalnega vijaka v medenični kosti, navedenega v literaturi. Na podlagi izvedenih preizkusov smo kot najprimernejše lepilo za nadaljnje eksperimentalne raziskave na medenici izbrali lepilo Loctite EA 9466. In experimental biomechanical studies of the pelvis, a reliable method of attaching elements to the bone is necessary to simulate muscle function, which enables load transfer without mechanically altering the bone’s structure. The purpose of this master’s thesis was to investigate the possibility of using adhesives for this attachment method and to determine the most suitable adhesive for further experimental research on the pelvis. To conduct the tests, a special testing setup was designed and built, and bone samples with corresponding test specimens were prepared. Four selected adhesives were compared experimentally: the medical adhesives Histoacryl and Dermabond as well as the technical adhesives Loctite 435 and Loctite EA 9466. The mechanical load-bearing capacity of the adhesive joints was determined through tensile tests, during which the force applied to each joint until failure was monitored. Loctite EA 9466 achieved the highest average maximum stress (376 N/cm²), followed by Loctite 435 (248 N/cm²), Dermabond (176 N/cm²), and Histoacryl (103 N/cm²). The results also demonstrated the influence of bone surface preparation and the quality of the test specimens’ fit on the load-bearing capacity and repeatability of the adhesive joints. The load-bearing capacity achieved with the Loctite EA 9466 adhesive was of a comparable order of magnitude to the pull-out force of an unreinforced 3.5 mm cortical screw in the pelvic bone, as reported in the literature. Based on the tests performed, Loctite EA 9466 was selected as the most suitable adhesive for further experimental research on the pelvis. kostno tkivo lepljeni spoji lepila biomehanika natezni preizkus medenica bone tissue adhesive joints adhesives biomechanics tensile testing pelvis true false false [K.
