Kuyang'anira zilonda za opaleshoni pambuyo pa opaleshoni ndi sitepe yofunikira kuti muteteze matenda, kupatukana kwa mabala ndi zovuta zina.

Komabe, malo opangira opaleshoniyo akakhala m'kati mwa thupi, kuyang'anitsitsa nthawi zambiri kumangoyang'ana pachipatala kapena kufufuza kwamtengo wapatali kwa ma radiological komwe nthawi zambiri amalephera kuzindikira zovuta zisanakhale zoika moyo pachiswe.

Masensa olimba a bioelectronic amatha kuyikidwa m'thupi kuti aziwunika mosalekeza, koma sangaphatikize bwino ndi minofu yachilonda.

Kuti azindikire zovuta zabala zikangochitika, gulu la ofufuza lotsogozedwa ndi Wothandizira Pulofesa John Ho wochokera ku NUS Electrical and Computer Engineering komanso NUS Institute for Health Innovation & Technology apanga suture yanzeru yomwe ilibe batri ndipo imatha. zindikirani popanda zingwe ndikufalitsa zambiri kuchokera kumalo opangira opaleshoni.

Ma sutures anzeruwa amaphatikiza kachipangizo kakang'ono kamagetsi komwe kamatha kuyang'anira kukhulupirika kwa bala, kutuluka kwa m'mimba ndi ma micromotions a minofu, pomwe amapereka machiritso omwe ali ofanana ndi ma sutures achipatala.

Kupambana kumeneku kunasindikizidwa koyamba mu magazini ya sayansiNature Biomedical Engineeringpa 15 October 2021.

Kodi ma sutures anzeru amagwira ntchito bwanji?

Kupangidwa kwa gulu la NUS kuli ndi zigawo zitatu zazikulu: suture ya silika yachipatala yomwe imakutidwa ndi polima yochititsa chidwi kuti iyankhe.opanda zingwe zizindikiro; sensa yamagetsi yopanda batri; ndi owerenga opanda zingwe omwe amagwiritsidwa ntchito popanga suture kuchokera kunja kwa thupi.

Ubwino umodzi wa ma sutures anzeruwa ndikuti kugwiritsa ntchito kwawo kumaphatikizapo kusinthidwa pang'ono kwa njira yopangira opaleshoni. Pa kusokera kwa bala, gawo lotsekereza la suture limalumikizidwa kudzera mu module yamagetsi ndikutetezedwa ndikugwiritsa ntchito silicone yamankhwala pazolumikizana zamagetsi.

Kuluka konse kwa opaleshoni ndiye kumagwira ntchito ngati achizindikiritso cha radio-frequency(RFID) tag ndipo imatha kuwerengedwa ndi wowerenga wakunja, yemwe amatumiza chizindikiro ku suture yanzeru ndikuzindikira chizindikirocho. Kusintha kwafupipafupi kwa chizindikiro chowonetserako kumasonyeza vuto lotheka la opaleshoni pa malo a bala.

Ma sutures anzeru amatha kuwerengedwa mpaka kuya kwa mamilimita 50, kutengera kutalika kwa nsonga zomwe zikukhudzidwa, ndipo kuya kungathe kukulitsidwa powonjezera kuwongolera kwa suture kapena kumva kwa owerenga opanda zingwe.

Mofanana ndi ma sutures omwe alipo kale, ma clip ndi ma staples, ma sutures anzeru amatha kuchotsedwa pambuyo pochita opaleshoni ndi njira yochepetsera pang'ono ya opaleshoni kapena endoscopic pamene chiopsezo cha zovuta chadutsa.

Kuzindikira msanga zovuta zabala

Kuti azindikire zovuta zosiyanasiyana - monga kutuluka kwa m'mimba ndi matenda - gulu lofufuza linaphimba sensa ndi mitundu yosiyanasiyana ya gel osakaniza polima.

Ma sutures anzeru amathanso kuzindikira ngati athyoka kapena kuphulika, mwachitsanzo, panthawi ya dehiscence (kupatukana kwa bala). Ngati suture yathyoledwa, wowerenga wakunja amatenga chizindikiro chochepa chifukwa cha kuchepetsa kutalika kwa mlongoti wopangidwa ndi suture wanzeru, kuchenjeza dokotala kuti achitepo kanthu.

Zotsatira zabwino zochiritsa, zotetezeka kuti zigwiritsidwe ntchito pachipatala

Poyesera, gululo lidawonetsa kuti mabala otsekedwa ndi ma sutures anzeru komanso osasinthika, masitayilo a silika achipatala onse amachiritsidwa mwachibadwa popanda kusiyana kwakukulu, ndipo poyamba amapereka phindu lowonjezera la kumvetsera opanda zingwe.

Gululi linayesanso ma sutures okhala ndi polima ndipo adapeza mphamvu zake ndi biotoxicity m'thupi sizidziwika ndi ma sutures wamba, komanso adawonetsetsa kuti mphamvu zomwe zimafunikira kuti zigwiritse ntchito dongosololi zinali zotetezeka kwa thupi la munthu.

Asst Prof Ho adati, "Pakadali pano, zovuta zomwe zimachitika pambuyo pa opaleshoni nthawi zambiri sizidziwikiratu mpaka wodwalayo atakhala ndi zizindikiro monga kupweteka, kutentha thupi, kapena kugunda kwa mtima. Ma sutures anzeruwa atha kugwiritsidwa ntchito ngati chida chochenjeza madokotala kuti alowererepo vutolo lisanakhale pachiwopsezo cha moyo, zomwe zingayambitse kuchepa kwa kuyambiranso, kuchira msanga, komanso zotsatira zabwino za odwala. ”

Kupititsa patsogolo

M'tsogolomu, gululi likuyang'ana kupanga owerenga opanda zingwe kuti alowe m'malo mwa khwekhwe lomwe likugwiritsidwa ntchito powerenga ma sutures opanda waya, zomwe zimathandiza kuyang'anitsitsa zovuta ngakhale kunja kwa zochitika zachipatala. Izi zitha kuthandiza odwala kuti atulutsidwe msanga m'chipatala atachitidwa opaleshoni.

Gululi tsopano likugwira ntchito ndi madokotala ochita opaleshoni ndi opanga zida zamankhwala kuti azitha kusintha ma sutures kuti azindikire kutuluka kwa magazi ndi kutuluka pambuyo pa opaleshoni ya m'mimba. Akuyang'ananso kuonjezera kuya kwa ntchito kwa sutures, zomwe zidzathandiza kuti ziwalo zakuya ndi minofu ziyang'anidwe.
