Ukubeka iliso kumanxeba otyando emva kotyando linyathelo elibalulekileyo lokuthintela usulelo, ukuhlukana kwamanxeba kunye nezinye iingxaki.
Nangona kunjalo, xa indawo yotyando inzulu emzimbeni, ukubeka iliso kuqhelekile kuqwalaselo lwezonyango okanye kuphando lweradiyoloji oluxabisa kakhulu oluhlala lusilela ukufumanisa iingxaki phambi kokuba zibe yingozi ebomini.
Izinzwa ze-bioelectronic ezinzima zinokumiliselwa emzimbeni ukuze zibekwe iliso rhoqo, kodwa zisenokungadibanisi kakuhle nezicubu zesilonda esibuthathaka.
Ukubona iingxaki zenxeba ngokukhawuleza xa zisenzeka, iqela labaphandi elikhokelwa nguNjingalwazi uJohn Ho ovela kwi-NUS Electrical and Computer Engineering kunye ne-NUS Institute for Health Innovation & Technology iye yaqulunqa i-suture ehlakaniphile engenabhethri kwaye inako. Iva ngeengcingo kwaye idlulise ulwazi olusuka kwiindawo ezinzulu zotyando.
Ezi zixhobo ezihlakaniphile zibandakanya i-sensor encinci ye-elektroniki ekwazi ukubeka iliso kwingqibelelo yesilonda, ukuvuza kwesisu kunye ne-micromotions yezicubu, ngelixa ibonelela ngeziphumo zokuphilisa ezilingana ne-sutures yebakala lezonyango.
Le mpumelelo yophando yapapashwa okokuqala kwijenali yenzululwaziUbunjineli beNdalo yeBiomedicalnge-15 ka-Okthobha 2021.
Zisebenza njani i-smart sutures?
Ukuveliswa kweqela le-NUS linamacandelo amathathu abalulekileyo: i-silk-grade ye-silk suture egqunywe ngepolymer eqhubayo ukuyivumela ukuba iphendule.Iimpawu ezingenazingcingo; inzwa ye-elektroniki engenabhetri; kunye nomfundi ongenazingcingo osetyenziselwa ukusebenzisa umthungo ovela ngaphandle komzimba.
Enye inzuzo yezi sutures ezihlakaniphile kukuba ukusetyenziswa kwazo kubandakanya ukuguqulwa okuncinci kwenkqubo yotyando eqhelekileyo. Ngethuba lokuthungwa kwesilonda, icandelo le-insulating ye-suture ifakwe kwimodyuli ye-elektroniki kwaye ikhuselekile ngokufaka i-silicone yonyango kuqhagamshelwano lombane.
Umthungo wonke wotyando ke usebenza njengeukuchongwa kwerediyo-frequency(RFID) ithegi kwaye inokufundwa ngumfundi wangaphandle, othumela umqondiso kwi-smart suture kwaye ibona umqondiso obonakalisiweyo. Utshintsho kwi-frequency yesignali ebonakalisiweyo ibonisa ingxaki enokwenzeka yokuhlinzwa kwindawo yesilonda.
I-smart sutures inokufundwa ukuya kubunzulu be-50 mm, kuxhomekeke kubude bemithungo ebandakanyekayo, kwaye ubunzulu bunokuba nokwandiswa ngakumbi ngokwandisa ukuhanjiswa kwe-suture okanye uvakalelo lomfundi ongenazintambo.
Ngokufana ne-sutures esele ikhona, iziqeshana kunye ne-staples, i-smart sutures inokususwa emva kokuhlinzwa ngokuhlinzwa okuncinci okanye inkqubo ye-endoscopic xa umngcipheko weengxaki udlulile.
Ukubona kwangethuba iingxaki zenxeba
Ukubona iintlobo ezahlukeneyo zeengxaki-ezifana nokuvuza kwesisu kunye nokusuleleka-iqela lophando lifake inzwa kunye neentlobo ezahlukeneyo ze-polymer gel.
I-smart sutures nayo iyakwazi ukufumanisa ukuba iphukile okanye ihlanjululwe, umzekelo, ngexesha lokutshatyalaliswa (ukuhlukana kwenxeba). Ukuba i-suture iphukile, umfundi wangaphandle uthatha umqondiso oncitshisiweyo ngenxa yokunciphisa ubude be-antenna eyenziwe yi-smart suture, elumkisa ugqirha ohambayo ukuba athathe inyathelo.
Iziphumo ezilungileyo zokuphilisa, zikhuselekile ukusetyenziswa kweklinikhi
Kuvavanyo, iqela libonise ukuba amanxeba avalwa zii-smart sutures kunye nezingalungiswanga, ii-silk ze-silk sutures zombini ziphiliswe ngokwemvelo ngaphandle kokwahluka okubalulekileyo, kunye neyokuqala ibonelela ngenzuzo eyongezelelweyo yokuvalelwa ngaphandle kwamacingo.
Iqela liphinde livavanye i-polymer-coated sutures kwaye yafumanisa amandla ayo kunye ne-biotoxicity emzimbeni yayingenakulinganiswa kwi-sutures eqhelekileyo, kwaye iphinde iqinisekise ukuba amanqanaba ombane afunekayo ekusebenzeni inkqubo akhuselekile kumzimba womntu.
UNjingalwazi uHo uthe, “Okwangoku, iingxaki zasemva kotyando azisoloko zibonwa de isigulana sibe neempawu zenkqubo ezifana neentlungu, umkhuhlane, okanye ukubetha kwentliziyo okuphezulu. Ezi sutures ezihlakaniphile zinokusetyenziswa njengesixhobo sokulumkisa kwangaphambili ukwenzela ukuba oogqirha bangenelele ngaphambi kokuba ingxaki ibe yingozi ebomini, nto leyo inokukhokelela kumazinga aphantsi okusebenza kwakhona, ukuchacha ngokukhawuleza, kunye neziphumo eziphuculweyo zesigulane. "
Uphuhliso olongezelelweyo
Kwixesha elizayo, iqela lijonge ukuphuhlisa umfundi ophathwayo ongenazingcingo ukuze athathe indawo yokuseta esetyenziswa ngoku ngaphandle kwamacingo ukufunda ii-smart sutures, evumela ukubekw' esweni kweengxaki nangaphandle koseto lweklinikhi. Oku kunokwenza ukuba izigulane ziphume kwangoko esibhedlele emva kotyando.
Iqela ngoku lisebenzisana noogqirha botyando kunye nabavelisi bezixhobo zonyango ukulungelelanisa i-sutures ukuze kubonwe ukopha kwenxeba kunye nokuvuza emva kotyando lwesisu. Bakwajonge ukwandisa ubunzulu bokusebenza kwee-sutures, eziza kwenza ukuba izitho ezinzulu kunye nezicubu zibekwe esweni.
