Ndi kukula kwa makina osindikizira a 3D, ndizotheka kuti 3D isindikize zokopa zanu kuchokera ku zitsanzo zomwe zimapezeka m'mabwalo otsegula.
Koma mitundu imeneyo ilibe mawonekedwe ogwiritsira ntchito zamagetsi monga omwe amapezeka m'ma prosthetics okwera mtengo, apamwamba kwambiri.
Tsopano, pulofesa wa Virginia Tech ndi gulu lake lamagulu osiyanasiyana ofufuza ophunzira omwe ali ndi maphunziro apamwamba apanga njira zophatikizira masensa amagetsi ndi ma prosthetics osindikizidwa a 3D - chitukuko chomwe tsiku lina chingapangitse ma prosthetics okwera mtengo opangira magetsi.
Kafukufuku wofalitsidwa kumene mu labu ya Blake Johnson, pulofesa wothandizira wa Virginia Tech mu engineering ya mafakitale ndi makina, adachitapo kanthu pakuwongolera magwiridwe antchito a makina ovala osindikizidwa a 3D.
Mwa kuphatikiza masensa amagetsi pamphambano pakati pa prosthetic ndi minofu ya wovala, ochita kafukufuku amatha kusonkhanitsa zambiri zokhudzana ndi ntchito ya prosthetic ndi chitonthozo, monga kupanikizika pa minofu ya wovala, zomwe zingathandize kusintha kuwonjezereka kwa mitundu iyi ya prosthetics.
Kuphatikizika kwa zida mkati mwa zigawo zoyenererana ndi ma prosthetics osindikizidwa a 3D pogwiritsa ntchito njira yosindikizira ya 3D, m'malo mophatikiza pamanja pambuyo pa kusindikiza, kungathenso kutsegulira njira ya mwayi wapadera wofananiza kuuma kwa minofu ya wovala ndikuphatikiza masensa osiyanasiyana. malo kudutsa mawonekedwe oyenerera mawonekedwe. Mosiyana ndi kusindikiza kwachikhalidwe kwa 3D komwe kumaphatikizapo kuyika zinthu mosanjikiza-ndi-wosanjikiza pamalo athyathyathya, kusindikiza kovomerezeka kwa 3D kumalola kuyika kwazinthu pamalo opindika ndi zinthu.
Malinga ndi Yuxin Tong, wophunzira womaliza maphunziro a engineering and systems engineering komanso mlembi woyamba wa kafukufuku wofalitsidwa, cholinga chachikulu ndikupanga njira zauinjiniya zomwe zitha kufikira anthu ambiri momwe zingathere, kuyambira ndi kuyesetsa kuthandizira kupanga makina opangira ma prosthetic amunthu. wachinyamata wakumaloko.
"Mwachiyembekezo, kholo lililonse litha kutsatira zomwe tafotokoza m'mapepala omwe tidasindikiza ndikupanga dzanja lopangira mwana lotsika mtengo," adatero Tong.
Kuti apange ma prosthetics ophatikizidwa ndi masensa amagetsi, ofufuzawo adayamba ndi 3D scanning data, yomwe ili yofanana ndi kujambula zithunzi pamakona osiyanasiyana kuti apeze mawonekedwe athunthu a chinthu - pankhaniyi, nkhungu ya nthambi ya wachinyamatayo.
Kenako adagwiritsa ntchito zowunikira za 3D kuti ziwongolere kuphatikizika kwa masensa kuti agwirizane ndi makina osindikizira a 3D pogwiritsa ntchito njira yosindikizira ya 3D.
Njira yopangidwa ndi gulu lofufuza ithandizira kuti ipitilize kugwiritsa ntchito mankhwala amunthu payekha komanso kapangidwe ka makina ovala.
"Kupanga makonda ndikusintha momwe zimagwirira ntchito pamakina ovala ovala pogwiritsa ntchito kusanthula kwa 3D ndi kusindikiza kwa 3D kumatsegula chitseko cha mapangidwe ndi kupanga matekinoloje atsopano othandizira anthu ndi chisamaliro chaumoyo komanso kuwunika mafunso ofunikira okhudzana ndi magwiridwe antchito ndi chitonthozo cha makina ovala. ,” anatero Johnson.
Kufufuza kwa Johnson m'manja opangira opaleshoni kunalimbikitsidwa atamva za mwana wamkazi wa mnzake, Josie Fraticelli, yemwe panthawiyo anali ndi zaka 12, yemwe anabadwa ndi amniotic band syndrome. Ali m'chiberekero, kukula kwa dzanja lake kunasiya. Zingwe zomangira amniotic zomangira zimachepetsa kuyenda kwa magazi komanso kukhudza kukula kwa dzanja lamanja, zomwe zimapangitsa kusapangana kupitirira ma knuckles.
Johnson adagwiritsa ntchito ukatswiri wake wokhudzana ndi kafukufuku wowonjezera wa biomanufacturing ndi gulu la ofufuza amitundu yosiyanasiyana omwe amaliza maphunziro awo ku 3D kusindikiza dzanja la bionic la Fraticelli lomwe lingakhale maziko a kafukufuku wosindikizidwa tsopano.
Pamene ankagwira ntchito ndi Fraticelli, adapitirizabe kukonza makina opangira ma prototype popanga njira zatsopano zopangira zowonjezera zomwe zingalole kuti chikhatho cha Fraticelli chigwirizane bwino, ndikupanga chipangizo chokomera bwino, chokhala ndi mawonekedwe.
Iwo adatsimikizira kuti makonda a prosthetic adakulitsa kulumikizana pakati pa minofu ya Fraticelli ndi prosthesis pafupifupi kanayi poyerekeza ndi zida zomwe sizinali zamunthu. Malo olumikizirana owonjezerekawa adawathandiza kudziwa komwe angatumizire ma electrode a sensing kuti ayese kufalikira kwa kuthamanga, zomwe zidawathandiza kupititsa patsogolo mapangidwewo.
Kuyesera kozindikira kunachitika pogwiritsa ntchito ma prosthetics awiri omwe ali ndi komanso opanda ma electrode. Poyendetsa zoyeserera izi ndi Fraticelli, adapeza kuti kugawa kwamphamvu kunali kosiyana pamene adapumula dzanja lake motsutsana ndi kugwira dzanja lake mosinthasintha.
"Kusagwirizana pakati pa khungu lofewa ndi mawonekedwe okhwima akadali vuto lomwe lingachepetse kufanana," adatero Tong. "Ma elekitirodi a sensing amatha kutsegulira malo ena atsopano kuti apititse patsogolo mapangidwe a prosthetics kuti athe kugawa bwino mphamvu."
Pazonse, Fraticelli amawona kuti pulojekiti yatsopanoyo imamuthandiza kuti azikhala bwino. Popeza kuti dzanja lake ndi lofewa komanso losinthika pansi pa machitidwe osiyanasiyana ndipo zinthu zopangira prosthetic zimakhala zolimba komanso zosasunthika, mlingo wa kufanana ukhoza kupitiriza kusintha.
Ma prosthetics amunthu akadali ndi malo oti asinthe, ndipo gulu la Johnson lipitiliza kufufuza ndikupanga njira zatsopano zopangira zowonjezera kuti ziwongolere pazida zovala za bionic.

Tiuzeni zomwe mukuganiza za ScienceDaily - timalandila ndemanga zabwino komanso zoyipa. Muli ndi vuto lililonse pogwiritsa ntchito tsambali? Mafunso?
