Ukuqapha amanxeba okuhlinzwa ngemva kokuhlinzwa kuyisinyathelo esibalulekile sokuvimbela ukutheleleka, ukuhlukana kwamanxeba nezinye izinkinga.
Kodwa-ke, lapho indawo yokuhlinza ijule emzimbeni, ukuqapha ngokuvamile kukhawulelwe ekuhlolweni komtholampilo noma uphenyo lwe-radiological olubizayo oluvame ukuhluleka ukuthola izinkinga ngaphambi kokuba zibe yingozi empilweni.
Izinzwa eziqinile ze-bioelectronic zingatshalwa emzimbeni ukuze ziqashwe ngokuqhubekayo, kodwa zingase zingahlangani kahle nezicubu zesilonda ezibucayi.
Ukuze kutholwe izinkinga zamanxeba ngokushesha nje lapho zenzeka, ithimba labacwaningi eliholwa uMsizi uSolwazi John Ho ovela kwa-NUS Electrical and Computer Engineering kanye ne-NUS Institute for Health Innovation & Technology lisungule umshuqulo ohlakaniphile ongenabhethri futhi ongakwazi. zizwela ngokungenantambo futhi udlulise ulwazi kusuka kumasayithi okuhlinza ajulile.
Lawa ma-smart sutures ahlanganisa inzwa encane ye-elekthronikhi ekwazi ukuqapha ubuqotho benxeba, ukuvuza kwesisu kanye nama-micromotions ezicubu, kuyilapho inikeza imiphumela yokuphulukisa elingana ne-sutures yebanga lezokwelapha.
Lokhu kuphumelela kocwaningo kwashicilelwa okokuqala kujenali yesayensiUbunjiniyela Bezobunjiniyela Bemvelongomhlaka-15 Okthoba 2021.
Asebenza kanjani ama-smart sutures?
Ukusungulwa kwethimba le-NUS kunezingxenye ezintathu ezibalulekile: i-suture yezinga lezokwelapha ehlanganiswe ne-polymer eqhubayo ukuyivumela ukuthi iphenduleamasignali angenantambo;inzwa kagesi engenabhethri;kanye nesifundi esingenantambo esisetshenziselwa ukusebenzisa umthungo ngaphandle komzimba.
Enye inzuzo yalawa ma-smart sutures ukuthi ukusetshenziswa kwawo kuhilela ukuguqulwa okuncane kwenqubo yokuhlinzwa evamile.Ngesikhathi sokuthunga isilonda, ingxenye yokuvikela ye-suture ifakwe nge-module ye-elekthronikhi futhi ivikelekile ngokusebenzisa i-silicone yezokwelapha kothintana nabo kagesi.
Wonke umthungo wokuhlinzwa ube esesebenza njenge-aukuhlonza i-radio-frequency(RFID) ithegi futhi ingafundwa ngumfundi wangaphandle, othumela isignali ku-smart suture futhi ithola isignali ebonisiwe.Ukuguqulwa kwemvamisa yesignali ebonisiwe kubonisa inkinga yokuhlinzwa engenzeka endaweni yenxeba.
Ama-smart sutures angafundwa aze afike ku-50 mm ukujula, kuye ngobude bezitishi ezihilelekile, futhi ukujula kungase kunwetshwe ngokukhuphula ukuqhutshwa kwe-suture noma ukuzwela komfundi ongenazintambo.
Ngokufanayo nama-sutures akhona, iziqeshana nezinto eziyisisekelo, ama-smart sutures angase akhishwe ngemva kokuhlinzwa ngokuhlinzwa okungavamisile noma inqubo ye-endoscopic lapho ingozi yezinkinga isidlulile.
Ukutholwa kusenesikhathi kwezinkinga zenxeba
Ukuze kutholwe izinhlobo ezihlukene zezinkinga—njengokuvuza kwesisu nokutheleleka—ithimba locwaningo lamboza inzwa ngezinhlobo ezahlukene zejeli ye-polymer.
Ama-smart sutures nawo ayakwazi ukubona ukuthi aphukile noma aqaqanjisiwe yini, isibonelo, ngesikhathi sokubola (ukuhlukaniswa kwamanxeba).Uma i-suture iphukile, umfundi wangaphandle uthatha isignali encishisiwe ngenxa yokunciphisa ubude be-antenna okwakhiwa i-smart suture, exwayisa udokotela okhona ukuthi athathe isinyathelo.
Imiphumela emihle yokuphulukisa, ephephile ukusetshenziswa emtholampilo
Ezivivinyweni, ithimba libonise ukuthi izilonda ezivalwe ama-smart sutures kanye nezindwangu zikasilika ezingashintshiwe, zombili zilulama ngokwemvelo ngaphandle komehluko omkhulu, kanti okokuqala kuhlinzeka ngenzuzo eyengeziwe yokuzwa okungenantambo.
Ithimba liphinde lahlola ama-sutures ane-polymer-coated futhi lathola amandla ayo kanye ne-biotoxicity emzimbeni kwakungabonakali kusuka ku-sutures evamile, futhi laqinisekisa ukuthi amazinga wamandla adingekayo ukuze kusetshenziswe uhlelo aphephile emzimbeni womuntu.
U-Ast Prof Ho uthe, “Okwamanje, izinkinga zangemva kokuhlinzwa ngokuvamile azibonwa kuze kube yilapho isiguli siba nezimpawu zesistimu njengobuhlungu, imfiva, noma ukushaya kwenhliziyo okuphezulu.Lawa ma-smart sutures angasetshenziswa njengethuluzi lokuxwayisa ngokushesha ukuze odokotela bakwazi ukungenelela ngaphambi kokuba inkinga ibe yingozi empilweni, okungaholela emazingeni aphansi okusebenza kabusha, ukululama ngokushesha, kanye nemiphumela ethuthukisiwe yesiguli.”
Ukuthuthukiswa okuqhubekayo
Ngokuzayo, ithimba libheke ukuthuthukisa isifundi esiphathwayo esingenazintambo ukuze singene esikhundleni sokusetha okwamanje okusetshenziselwa ukufunda ngaphandle kwentambo ama-smart sutures, okuvumela ukubhekwa kwezinkinga ngisho nangaphandle kwezilungiselelo zomtholampilo.Lokhu kungenza iziguli zisheshe ziphume esibhedlela ngemuva kokuhlinzwa.
Ithimba manje lisebenzisana nodokotela abahlinzayo nabakhiqizi bemishini yezokwelapha ukuze bajwayelane nemishini yokuthunga ukuze kutholwe ukopha kwenxeba nokuvuza ngemva kokuhlinzwa emathunjini.Babheke nokwandisa ukujula kokusebenza kwe-sutures, okuzokwenza ukuthi izitho ezijulile nezicubu ziqashwe.
