Kuongorora maronda ekuvhiya mushure mekuvhiyiwa inhanho yakakosha yekudzivirira kutapukirwa, kupatsanurwa kwemaronda uye mamwe matambudziko.
Nekudaro, kana nzvimbo yekuvhiya yakadzika mumuviri, kutarisisa kunowanzo kugumira kuongororo yekiriniki kana inodhura yekuongorora radiological iyo inowanzotadza kuona matambudziko asati atyisidzira hupenyu.
Hard bioelectronic sensors inogona kuisirwa mumuviri kuti irambe ichitariswa, asi inogona kusabatana zvakanaka neanonzwa maronda tishu.
Kuti vaone kunetsa kwemaronda pavanenge vangoitika, chikwata chevaongorori chinotungamirwa naMubatsiri Muzvinafundo John Ho kubva kuNUS Electrical and Computer Engineering pamwe neNUS Institute for Health Innovation & Technology vakagadzira suture yakangwara isina bhatiri uye inogona. isina waya inonzwisisa uye kuendesa ruzivo kubva pakadzika nzvimbo dzekuvhiya.
Aya akangwara sutures anosanganisira diki yemagetsi sensor inogona kutarisa kuvimbika kweronda, gastric leakage uye tissue micromotions, uku ichipa kuporesa mhedzisiro iyo yakaenzana neyekurapa-giredhi sutures.
Iyi tsvakiridzo yebudiriro yakatanga kuburitswa mujenari resainziNature Biomedical Engineeringmusi wa15 Gumiguru 2021.
Iyo smart sutures inoshanda sei?
Kugadzirwa kwechikwata cheNUS chine zvinhu zvitatu zvakakosha: yekurapa-giredhi sirika suture iyo yakashongedzwa ne conductive polymer kuibvumira kupindura kune.masaini masaini;sensor yemagetsi isina bhatiri;uye muverengi asina waya anoshandiswa kushandisa suture kubva kunze kwemuviri.
Imwe mukana weaya akangwara sutures ndeyekuti kushandiswa kwavo kunosanganisira kushoma kugadziridzwa kweyakajairwa kuvhiya maitiro.Panguva yekucheka kwevanga, chikamu chekudzivirira che suture chinosungirirwa kuburikidza nemagetsi module uye chakachengetedzwa nekushandisa silicone yezvokurapa kune magetsi.
Iyo yese yekuvhiya musono inozoshanda searadio-frequency identification(RFID) tag uye inogona kuverengerwa nemuverengi wekunze, iyo inotumira chiratidzo kune smart suture uye inoona chiratidzo chinoratidzwa.Kuchinja kwehuwandu hwechiratidzo chakaratidzwa kunoratidza kukanganisa kunogoneka kwekuvhiya panzvimbo yeronda.
Iwo smart sutures anogona kuverengerwa kusvika pakadzika 50 mm, zvichienderana nehurefu hwemastitches anobatanidzwa, uye kudzika kunogona kuwedzeredzwa nekuwedzera conductivity ye suture kana kunzwisiswa kweasina waya muverengi.
Zvakafanana nezviripo sutures, clips uye staples, iyo smart sutures inogona kubviswa-yakaitwa mushure mekuvhiyiwa nekuvhiya kushoma kana endoscopic maitiro kana njodzi yekunetseka yapfuura.
Kukurumidza kuona matambudziko eronda
Kuti uone marudzi akasiyana ematambudziko-akadai segastric leakage uye kutapukirwa-chikwata chekutsvagisa chakafukidza sensor nemhando dzakasiyana dzepolymer gel.
Iyo smart sutures inokwanisawo kuona kana yakaputsika kana kuvhurika, semuenzaniso, panguva yedehiscence (kuparadzaniswa kwemaronda).Kana suture yakaputsika, muverengi wekunze anotora chiratidzo chakaderedzwa nekuda kwekuderedzwa kwehurefu hweantenna inoumbwa nesmart suture, ichinyevera chiremba anouya kuti atore chiito.
Migumisiro yakanaka yekuporesa, yakachengeteka kushandiswa kwekliniki
Mukuedza, timu yakaratidza kuti maronda akavharwa neakangwara sutures uye asina kugadziridzwa, ekurapa-giredhi sirika sutures ese akapora zvega pasina mutsauko wakakura, neyekutanga ichipa iyo yakawedzerwa bhenefiti yekunzwa isina waya.
Chikwata ichi chakaedzawo mapolymer-coated sutures uye akawana simba rayo uye biotoxicity kumuviri zvaive zvisingazivikanwe kubva kune akajairwa sutures, uye zvakare ive nechokwadi chekuti mazinga emagetsi anodiwa kushandisa sisitimu aive akachengeteka kumuviri wemunhu.
Asst Prof Ho vakati, "Parizvino, matambudziko mushure mekuvhiyiwa kazhinji haaonekwe kudzamara murwere asangana nezviratidzo zvakaita sekurwadziwa, fivha, kana kurova kwemoyo kwakanyanya.Aya akangwara sutures anogona kushandiswa sechishandiso chekutanga chekuzivisa kuti vanachiremba vagone kupindira dambudziko risati ratyisa hupenyu, izvo zvinogona kutungamira kuderedzwa kwemitengo yekushandazve, kukurumidza kupora, uye kuvandudzwa kwemhedzisiro yemurwere. "
Kumwe budiriro
Mune ramangwana, timu iri kutsvaga kugadzira inotakurika isina waya muverengi kutsiva iyo yekuseta ikozvino inoshandiswa kuverenga pasina waya iyo smart sutures, ichigonesa kuongororwa kwematambudziko kunyangwe kunze kwekiriniki marongero.Izvi zvinogona kuita kuti varwere vakwanise kuburitswa muchipatara mushure mekuvhiyiwa.
Chikwata ichi chave kushanda nevarapi nevagadziri vemidziyo yekurapa kuti vagadzirise sutures yekuona kubuda kweronda nekubuda mushure mekuvhiyiwa kwedumbu.Ivo zvakare vari kutarisa kuwedzera kudzika kwekushanda kweiyo sutures, izvo zvinogonesa yakadzika nhengo uye tishu kuti zvitariswe.
