Ukwenza ukuhlinzwa akuyona isayensi ephelele, futhi ngisho nodokotela kudingeka baqeqeshe amakhono abo, ikakhulukazi uma kuziwa ezinganeni. Ukuze bacije lawo makhono, odokotela benza amasu ahlukahlukene besebenzisa amamodeli e-anatomical noma ama-mannequins. Kodwa-ke, lokhu kuvame ukukhawulela mayelana nobunkimbinkimbi nomuzwa, okhawulela ukuqeqeshwa.
Ukuze unqobe leyo mikhawulo, i-Ph.D. umfundi we-grad UMark Thielen (Eindhoven University of Technology) ngosizo lwe Izindawo ze-3D, iklame i-mannequin yengane enemininingwane eshaqisayo enohlaka lwamathambo oluphrintiwe lwe-3D olunezitho zangaphakathi ezisebenzayo.
UMark waqala ukuklama imodeli yesibonelo esebenzisa izikena ze-MRI azithatha kusukela enganeni yangempela, eyayilungele izinga lemininingwane edingekayo kuphrojekthi. Wabe esefaka usizo lwe-3D Hub ukuze aguqule lezo zikena ze-3D zibe imodeli elungile ngokwemvelo futhi waqala ukuhlola izinto ezimbalwa ukuze abone ukuthi yini esebenze kangcono kakhulu kuhlelo lwezokwelapha.
Uhlaka lwamathambo emodeli luqukethe izingxenye ezimbili, i-ribcage nomgogodla, kokubili okuyi-3D okuphrintwe ngephrinta ye-SLS 3D kusetshenziswa ama-thermoplastic elastomers, ahlala izitho ezisebenzayo. UMark waklama inhliziyo namaphaphu ukuthi asebenze ngokufana nozakwabo bezinto eziphilayo. Okusho ukuthi, inhliziyo ihlanganisa ama-valve asebenzayo ukumpompa uketshezi, futhi amaphaphu avuthele/anciphe ukuze alingise ukuphefumula.
Izitho zemodeli zaphrintwa nge-3D kusetshenziswa inqubo yokuphrinta ye-PolyJet kusetshenziswa irabha ye-thermoplastic elastomer (TPE), ezivumela ukuthi zinwebe futhi zihlehle lapho ziphampa uketshezi noma ukuphefumula okufanisiwe. Ngaphezu kwalokho, izitho zifakwe izinzwa ezishumekiwe, ezithola/zikala ingcindezi, ingcindezi, kanye nomthelela lapho kuhlolwa udokotela. Amakhamera amancane nawo afakwe ngaphakathi, anikeza umbono wangaphakathi ngenkathi kwenziwa izinqubo ezingenzeka.
Lolo ketshezi lusiza futhi ekunikezeni impendulo kubaqeqeshwayo futhi lungasetshenziswa ukunquma ukuthi ingcindezi iphezulu kakhulu noma iphansi, ilingisa ukugeleza kwegazi ngaphansi kwengcindezi. Nakuba imodeli ye-medical mannequin ka-Mark isesesigabeni se-prototype futhi isathuthukiswa, uthemba ukuthi izosetshenziswa ochwepheshe bezokwelapha esikhathini esithile maduze nje.
Uqhubeka athi, “I kholelwa ukuthi ukuthuthukisa nokuthuthukisa esikuqale lapha kungasiza ucwaningo lwezokwelapha endaweni ebanzi. Singakwazi ukudala amamodeli esiguli angokoqobo wezinye izingxenye zomzimba ukuze siqinise ukuqeqeshwa kwezokwelapha ngezinqubo eziphuthumayo nokukhulelwa. "
