Ar \u012fmanoma sukurti implant\u0105, kuris ne tik pakeist\u0173 pa\u017eeist\u0105 audin\u012f, bet ir paskatint\u0173 organizm\u0105 j\u012f visi\u0161kai atkurti? Dar visai neseniai tai atrod\u0117 kaip mokslin\u0117 fantastika, ta\u010diau \u0161iandien pa\u017eangios biomedicinin\u0117s med\u017eiagos ir 3D spausdinimo technologijos vis spar\u010diau priartina toki\u0105 galimyb\u0119 prie klinikin\u0117s praktikos.<\/strong><\/p>

3D spausdinimas medicinoje jau seniai neb\u0117ra vien technologija, skirta anatominiams modeliams ar plastikin\u0117ms detal\u0117ms gaminti. \u0160iandien jis tampa vienu svarbiausi\u0173 \u012franki\u0173 kuriant individualizuotus implantus ir pa\u017eangias medicinos priemones.<\/p>

Galimyb\u0117 sluoksnis po sluoksnio formuoti sud\u0117tingas trimates strukt\u016bras pagal skaitmenin\u012f model\u012f ir sukurti implantus atveria naujas galimybes gydyti pacientus tiksliau, grei\u010diau ir efektyviau.<\/p>

Kod\u0117l svarbiausia yra ne 3D spausdintuvas, o med\u017eiaga?<\/strong><\/p>

\"\"<\/figure>

Vien \u012frangos nepakanka \u2013 implanto s\u0117km\u0119 pirmiausia lemia biomedicinin\u0117 med\u017eiaga. Ji turi b\u016bti suderinama su \u017emogaus biologin\u0117mis sistemomis, netoksi\u0161ka, pasi\u017eym\u0117ti tinkamomis mechanin\u0117mis savyb\u0117mis ir, priklausomai nuo paskirties, geb\u0117ti palaipsniui suirti, sudarydama s\u0105lygas nat\u016braliam audini\u0173 atsik\u016brimui.<\/p>

Kadangi skirtingi \u017emogaus audiniai pasi\u017eymi skirtingomis savyb\u0117mis, universalios med\u017eiagos visiems implantams n\u0117ra. Kiet\u0173j\u0173 audini\u0173, pavyzd\u017eiui, kaulo regeneracijai da\u017eniausiai kuriami kompozitai, derinant bioskaid\u017eius polimerus su bioaktyviais u\u017epildais, tokiais kaip hidroksiapatitas ar \u03b2-trikalcio fosfatas.<\/p>

\"\"<\/figure>

Tokios med\u017eiagos suteikia karkasui pakankam\u0105 mechanin\u012f tvirtum\u0105 ir kartu pagerina biologines savybes. Tuo tarpu kremzl\u0117s, odos, kraujagysli\u0173 regeneracijai reikalingos elastingesn\u0117s med\u017eiagos.<\/p>

Nuo studij\u0173 iki mokslini\u0173 tyrim\u0173<\/strong><\/p>

Toki\u0173 biomedicinini\u0173 med\u017eiag\u0173 k\u016brimas reikalauja tarpdisciplinini\u0173 \u017eini\u0173 ir praktini\u0173 geb\u0117jim\u0173. Tam b\u016btina suprasti biologinius procesus, i\u0161manyti in\u017einerinius sprendimus ir geb\u0117ti taikyti pa\u017eangias gamybos technologijas.<\/p>

B\u016btent tokius specialistus rengia Kauno technologijos universiteto Chemin\u0117s technologijos fakulteto (KTU CTF) Biomedicinini\u0173 med\u017eiag\u0173 industrijos studij\u0173 programa<\/a>, kurioje derinamos chemijos, biologijos, med\u017eiag\u0173 mokslo ir in\u017einerijos \u017einios kuriant pa\u017eangias biomedicinines med\u017eiagas medicinai.<\/strong><\/p>

Vienas i\u0161 \u0161ios srities jaun\u0173j\u0173 tyr\u0117j\u0173 \u2013 KTU doktorantas Jok\u016bbas Luko\u0161i\u016bnas. Jau antrus metus jis tiria biomedicinines med\u017eiagas ir kuria bioaktyvius 3D spausdintus karkasus, skirtus kaulinio audinio regeneracijai.<\/p>

Jo atliekami tyrimai apima vis\u0105 inovacijos k\u016brimo grandin\u0119 \u2013 nuo kompiuterinio modeliavimo, nauj\u0173 med\u017eiag\u0173 sintez\u0117s ir j\u0173 savybi\u0173 tyrim\u0173 iki bioaktyvi\u0173 kaulo regeneracijai skirt\u0173 karkas\u0173 k\u016brimo.<\/p>

Kai implantas tampa pagalbininku organizmui<\/strong><\/p>

Viena i\u0161 sri\u010di\u0173, kurioje tokie bioaktyv\u016bs karkasai gal\u0117t\u0173 b\u016bti pla\u010diai pritaikomi, yra veido ir \u017eandikauli\u0173 chirurgija. Netekus dant\u0173 da\u017enai prasideda \u017eandikaulio kaulo nykimas, tod\u0117l daliai pacient\u0173 kaulo kiekio nepakanka dant\u0173 implantui \u012fsriegti.<\/p>

Tokiais atvejais atliekama kaulo priauginimo proced\u016bra, kurios metu da\u017eniausiai naudojamas i\u0161 kitos paciento k\u016bno vietos paimtas kaulas. Ta\u010diau papildoma operacija rei\u0161kia ilgesn\u012f gijimo laikotarp\u012f, didesn\u0119 komplikacij\u0173 rizik\u0105 ir didesn\u012f diskomfort\u0105 pacientui.<\/p>

Tokiais atvejais perspektyvia alternatyva gal\u0117t\u0173 tapti 3D spausdinti bioaktyv\u016bs karkasai. Implantuotas \u012f kaulo defekt\u0105, toks karkasas veikia kaip laikina atrama, prie kurios prisitvirtina l\u0105stel\u0117s ir pradeda formuoti nauj\u0105 kaulin\u012f audin\u012f.<\/p>

Vykstant gijimo procesui, karkasas palaipsniui rezorbuojasi, o jo viet\u0105 u\u017eima nat\u016braliai susiformav\u0119s paciento kaulas. Taip implantas tampa ne pasyviu pakaitalu, o aktyvia audini\u0173 regeneracijos proceso dalimi.<\/p>

Nors iki plataus toki\u0173 implant\u0173 taikymo klinikin\u0117je praktikoje dar reikalingi i\u0161sam\u016bs ikiklinikiniai ir klinikiniai tyrimai, \u0161iandien kuriamos technologijos jau leid\u017eia matyti ai\u0161ki\u0105 ateities krypt\u012f.<\/p>

Individualizuoti implantai, pa\u017eangios biomedicinin\u0117s med\u017eiagos ir 3D spausdinimas tampa vienais svarbiausi\u0173 regeneracin\u0117s medicinos varikli\u0173, atverian\u010di\u0173 galimybes tiksliau ir efektyviau atkurti pa\u017eeistus audinius.<\/p>","protected":false},"excerpt":{"rendered":"
