Hāʻawi ʻia nā kiʻi no ka hoʻoiho ʻana ma ka pūnaewele ʻo MIT Press Office i nā hui kūʻai ʻole, ka paʻi, a me ka lehulehu ma lalo o kahi Creative Commons Attribution Non-Commercial Non-Derivative License. ka nui kūpono. Pono e hoʻohana ʻia ke kālā i ke kope ʻana i nā kiʻi;inā ʻaʻole i hāʻawi ʻia ma lalo, e hōʻaiʻē iā "MIT" no nā kiʻi.
Ua hoʻomohala ka poʻe ʻenekinia MIT i kahi lopako e like me ka uea hoʻokele magnetic e hiki ke holo ikaika ma nā ala haiki a wiliwili, e like me ka labyrinthine vasculature o ka lolo.
I ka wā e hiki mai ana, hiki ke hoʻohui ʻia kēia kaula robotic me ka ʻenehana endovascular e loaʻa ana, e ʻae i nā kauka e alakaʻi mamao i kahi robot ma o nā kīʻaha koko lolo o ka mea maʻi e mālama wikiwiki i nā blockages a me nā ʻeha, e like me nā mea i loaʻa i nā aneurysms a me nā hahau.
"ʻO ka hahau ka lima o ke kumu nui o ka make a me ke kumu nui o ke kino kīnā ma ʻAmelika Hui Pū ʻIa.Inā hiki ke mālama ʻia ka maʻi maʻi maʻi i loko o nā minuke 90 mua a i ʻole, e hoʻomaikaʻi maikaʻi ʻia ke ola o ka poʻe maʻi, "wahi a MIT Mechanical Engineering a me Zhao Xuanhe, ke kaukaʻi pili o ka ʻenekinia kīwila a me ke kaiapuni. ka hoʻopaʻa ʻana i kēia wā 'prime time', hiki iā mākou ke pale i ka pōʻino mau loa.ʻO ia ko mākou manaʻolana.
ʻO Zhao a me kāna hui, me ka mea kākau alakaʻi ʻo Yoonho Kim, he haumāna puka ma ke Keʻena ʻOihana Mechanical o MIT, e wehewehe i kā lākou hoʻolālā robot palupalu i kēia lā ma ka puke pai Science Robotics. ʻO nā mea kākau ʻē aʻe o ka pepa ʻo MIT haumāna puka ʻo German Alberto Parada a me ka haumāna kipa.

No ka wehe ʻana i nā ʻōpū koko mai ka lolo, hana maʻamau nā kauka i ke ʻoki endovascular, kahi kaʻina hana liʻiliʻi e hoʻokomo ai ke kauka i kahi kaula lahilahi ma o ke aʻa nui o ka mea maʻi, maʻamau i ka wāwae a i ʻole ka ʻāʻī. kiʻi i nā kīʻaha koko, a laila e hoʻohuli lima ke kauka lapaʻau i ka uwea i loko o nā kīʻaha koko lolo i poino.
Hiki i ke kaʻina hana ke koi kino, wahi a Kim, a koi i nā kauka lapaʻau e hoʻomaʻamaʻa kūikawā e pale i ka hoʻolaha pinepine ʻana o ka fluoroscopy.
"He akamai koʻikoʻi loa ia, a ʻaʻole lawa nā kauka lapaʻau e lawelawe i nā poʻe maʻi, ʻoi aku hoʻi ma nā wahi kūloko a i ʻole nā ​​​​wahi kuaʻāina," wahi a Kim.
ʻO nā alakaʻi alakaʻi lāʻau lapaʻau i hoʻohana ʻia i ia mau kaʻina hana he passive, ʻo ia hoʻi, pono e hoʻohana ʻia me ka lima, a hana pinepine ʻia me ke kumu metala a uhi ʻia me ka polymer, kahi a Kim i ʻōlelo ai e hiki ke hana i ka friction a hōʻino i ka uhi o nā kīʻaha koko. wahi paʻa.
Ua ʻike ka hui e hiki i nā mea hoʻomohala i loko o kā lākou lab ke kōkua i ka hoʻomaikaʻi ʻana i nā kaʻina hana endovascular, ma ka hoʻolālā ʻana i nā uea alakaʻi a me ka hōʻemi ʻana i ka ʻike ʻana o nā kauka i kekahi radiation pili.
I nā makahiki i hala iho nei, ua kūkulu ka hui i ka ʻike ma nā hydrogels (nā mea biocompatible ka nui o ka wai) a me 3D paʻi magneto-actuated mea hiki ke hoʻolālā ʻia e kolo, lele a hopu i ka pōpō, ma ka hahai ʻana i ke kuhikuhi o ka magnet.
I loko o ka pepa hou, ua hui nā mea noiʻi i kā lākou hana ma nā hydrogels a me ka hana magnetic e hana i kahi uea robotic magnetically steerable, hydrogel-coated robotic wire, a i ʻole guidewire, i hiki ai iā lākou ke hana lahilahi e alakaʻi i nā kīʻaha koko ma o ka lolo silicone replica lolo. .
ʻO ke kumu o ka uea robotic i hana ʻia me ka nickel-titanium alloy, a i ʻole "nitinol," he mea hiki ke hoʻopaʻa ʻia a elastic. ʻO ka maʻalahi i ka wā e hoʻopili ai i nā kīʻaha koko koʻikoʻi.
ʻO ka hope, ua hoʻohana lākou i kahi kaʻina hana kemika a lākou i hoʻomohala mua ai e ʻaʻahu a hoʻopaʻa i ka overlay magnetic me kahi hydrogel-he mea ʻaʻole e hoʻopilikia i ka pane ʻana o nā ʻāpana magnetic lalo, ʻoiai e hāʻawi ana i kahi ʻili paheʻe, Friction-free, biocompatible.
Ua hōʻike lākou i ka pololei a me ka hoʻoikaika ʻana o ka uea robotic ma o ka hoʻohana ʻana i kahi magnet nui (e like me ke kaula o ka papeti) e alakaʻi i ka uea ma ke ala keʻakeʻa o kahi loop liʻiliʻi, e hoʻomanaʻo ana i kahi uea e hele ana ma ka maka o ka nila.
Ua hoʻāʻo pū nā mea noiʻi i ka uea i loko o kahi kope silicone nui o nā kīʻaha koko nui o ka lolo, me nā clots a me nā aneurysms, e hoʻohālikelike ana i nā CT scans o ka lolo o ka mea maʻi maoli. , a laila hoʻohana lima lima i nā magnet nui a puni ke kumu hoʻohālike e alakaʻi i ka lopako ma ke ala wili a haiki o ka ipu.
Hiki ke hoʻohana ʻia nā kaula robotic, wahi a Kim, ʻo ia hoʻi, hiki ke hoʻohui ʻia ka hana - no ka laʻana, ka hāʻawi ʻana i nā lāʻau lapaʻau e hōʻemi ai i ke koko a i ʻole ka haki ʻana i nā poloka me nā lasers. hiki iā lākou ke alakaʻi i ka lopako a hoʻōla i ka laser i kona hiki ʻana i ka wahi i manaʻo ʻia.
I ka hoʻohālikelike ʻana o ka poʻe noiʻi i ka uea robotic hydrogel-coated me ka uea robotic uncoated, ua ʻike lākou ua hāʻawi ka hydrogel i ka uea me kahi pono paheʻe i makemake nui ʻia, e ʻae iā ia e holo ma nā wahi paʻa me ka ʻole e hoʻopaʻa ʻia. ʻO kēia waiwai ke kī i ka pale ʻana i ke kuʻekuʻe a me ka pōʻino i ke kapa o ka moku i ka hala ʻana o ke kaula.
"ʻO kahi paʻakikī i ka ʻoki ʻana ʻo ka hiki ke hele i nā kīʻaha koko paʻakikī i loko o ka lolo liʻiliʻi i ke anawaena ʻaʻole hiki ke hiki i nā catheters pāʻoihana," wahi a Kyujin Cho, he loea o ka ʻenekinia mechanical ma Seoul National University."Ke hōʻike nei kēia haʻawina pehea e lanakila ai i kēia pilikia.hiki a hiki i nā kaʻina hana ʻokiʻoki i loko o ka lolo me ka ʻole o ka wehe ʻana.
Pehea e pale ai keia lopako lopako hou i na kanaka lapaau mai ka radiation? Na ka magnetically steerable guidewire e hoopau i ka pono o na kanaka lapaau e hookui i ke uwea i loko o ke koko o ka mea ma'i, wahi a Kim. ʻO ia hoʻi, ʻaʻole pono ke kauka e pili kokoke i ka mea maʻi a ʻO ka mea nui loa, ʻo ka fluoroscope e hoʻopuka ai i ka radiation.
I ka wā e hiki mai ana, manaʻo ʻo ia e hoʻokomo i ka ʻenehana endovascular i loaʻa, e like me nā pālua o nā magnet nui, e ʻae ana i nā kauka ma waho o ka lumi hana, mai nā fluoroscopes e kiʻi i nā lolo o nā maʻi, a i ʻole ma nā wahi ʻokoʻa loa.
"Hiki i nā paepae e kū nei ke hoʻohana i kahi māla magnetic i ka mea maʻi a hana i ka fluoroscopy i ka manawa like, a hiki i ke kauka ke hoʻomalu i ke kahua magnetic me ka hauʻoli i loko o kahi lumi ʻē aʻe, a i ʻole ma kekahi kūlanakauhale ʻē aʻe," wahi a Kim. e hoʻohana i ka ʻenehana i kēia manawa i ka pae aʻe e hoʻāʻo i kā mākou kaula robotic i vivo.
Loaʻa ke kālā no ka noiʻi ʻana mai ka Office of Naval Research, MIT's Soldier Nanotechnology Institute, a me ka National Science Foundation (NSF).
Ua kākau ʻo Becky Ferreira, ka mea kākau moʻo papa papa, ua hoʻomohala nā mea noiʻi MIT i kahi kaula robotic i hiki ke hoʻohana ʻia no ka mālama ʻana i nā ʻōpū koko neurological a i ʻole ka hahau.Hiki i kēia ʻano ʻenehana liʻiliʻi invasive ke kōkua i ka hoʻēmi ʻana i ka pōʻino mai nā pilikia pilikia neurological e like me nā hahau.
Ua hana nā mea noiʻi MIT i kahi kaula hou o nā robotics magnetron e hiki ke hele i loko o ka lolo o ke kanaka, kākau ʻo Smithsonian reporter Jason Daley.
Ua kākau ka mea kākau moʻolelo TechCrunch Darrell Etherington ua hoʻomohala ka poʻe noiʻi MI i kahi kaula robotic hou e hiki ke hoʻohana ʻia e hoʻemi i ka hōʻeha ʻana o ka lolo. nā ʻeha e hiki ai ke alakaʻi i nā aneurysms a me nā hahau.
Ua hoʻomohala ka poʻe noiʻi MIT i kahi ilo robotic magnetically controlled hou i hiki i kekahi lā ke kōkua i ka hoʻohaʻahaʻa ʻana i ke ʻano o ka lolo, hōʻike ʻo New Scientist's Chris Stocker-Walker. hiki i nā aʻa koko.
Ua kākau ka mea kākau moʻolelo ʻo Gizmodo ʻo Andrew Liszewski e hiki ke hoʻohana ʻia kahi hana robotic hou e like me ke kaula i hoʻomohala ʻia e nā mea noiʻi MIT e hoʻomaʻemaʻe koke i nā blockages a me nā clots e kumu ai ka hahau. e hoʻomanawanui pinepine ʻia e nā kauka lapaʻau," wehewehe ʻo Liszewski.
