Suture PGA Medical oo leh Tolmo Qalloocan oo Irbado la tuuri karo
Polyglactinesuture wuxuu ka kooban yahay dunta tolitaanka ee ku xiran irbad tol ah.Irbadda tolku waxay ka samaysan tahay bir aan tayo lahayn oo tayo sare leh oo gaar ah oo loogu talagalay codsiyada caafimaadka waxayna si adag ugu dheggan tahay dunta tolitaanka.Tollida (durka irbadda) waxa loo isticmaalaa in lagu tolo unug jilicsan ee jidhka bini'aadamka.Polyglactine waa qalliin nadiif ah oo nadiif ah oo la nuugi karo oo isku dhafan oo ka kooban glycolic (90%) iyo L-Lactide (10%) samaynta kobolymer.Duubka tolitaanka ee Polyglactine waa tidcan oo lagu dahaadhay kalsiyum sterate iyo Polyglactine 370. Dunta tolmada iyo dahaadhka waxaa nuugi kara jidhka bini'aadamka iyada oo loo marayo hydrolysis taas oo aan waxyeello u lahayn jidhka bini'aadamka.Sutures Polyglactine waxay buuxisaa dhammaan shuruudaha USP iyo Pharmacopoeia ee Yurub ee tolidda-sayntetic ee la nuugi karo.

PGLA tolmo la nuugi karo oo caafimaad
Marka la wanaajiyo kakanaanta iyo shuruudaha farsamada ee qalliinka gudaha ee bini'aadamka, tolida nuugista ee la isticmaalo waa in aysan haysan oo kaliya xoog gaar ah, laakiin sidoo kale waxay awood u leedahay inay si tartiib tartiib ah u hoos u dhigto oo ay nuugo jirka oo leh bogsashada dhaawaca.Poly (ethyl lactide - lactide) (PGLA) waa mid ka mid ah agabka biomedical ee ugu qiimaha badan uguna rajo badan, kaas oo loo isticmaali karo in lagu sameeyo tolmo la nuugi karo.Tianhe BRAND PGLA tolmo caafimaad oo la nuugi karo ayaa laga sameeyay copolymerization of ethyl lactide iyo lactide iyadoo loo eegayo saamiga loo baahan yahay, iyada oo loo marayo wareejinta, kala bixinta, tolmada, dahaarka iyo habab kale.Tolidan la nuugi karo waxay leedahay biocompatibility wanaagsan, ma jiro falcelin cad oo unug ah oo ku saabsan jidhka bini'aadamka, xoog sare, dherer dhexdhexaad ah, aan sun ahayn, xanaaq la'aan, dabacsanaan iyo hoos u dhac wanaagsan (alaabta xaalufka waa carbon dioxide iyo biyaha).
Qalabka ceeriin ee badeecada waxaa laga soo dejiyey poly (ethyl lactide - lactide), kaas oo ay miiqdaan oo ay tolto shirkadeena.Walaxda hydrolyzed ee alaabta waxaa nuugi kara jidhka bini'aadamka, falcelinta nudaha ayaa hooseysa.Waa badeecad la cusboonaysiiyay si loo hagaajiyo xanuunka qalliinka.
· Xoog adkaysi sare
Xoogga jilitaanka ayaa lagu hayn karaa in ka badan 5-7 maalmood si loo bogsiiyo nabarrada, iyo xoogga guntinku aad ayuu uga sarreeyaa kan dunta mindhicirka, siinta badbaadada bukaanka.Laqabsiga noole ee wanaagsan
Wax dareen ah uma laha jidhka bini'aadamka, ma jiro cytotoxicity, ma laha sunta hidde-sideyaasha, ma laha kicin, waxayna kor u qaadi kartaa korriinka unugyada isku-xidhka fibrous ee gudaha.- nuugista lagu kalsoonaan karo
Alaabta ayaa lagu nuugi karaa jidhka bini'aadamka iyada oo loo marayo hydrolysis.Nuugista waxay bilaabataa 15 maalmood ka dib marka la geliyo, iyadoo inta badan nuugista 30 maalmood ka dib oo dhammaystirto nuugista 60-90 maalmood ka dib.- fududahay in la shaqeeyo
Alaabtani waa mid jilicsan, dareen fiican leh, siman marka la isticmaalayo, jiidashada ururka oo hooseeya, fududahay in la xidho, adag, ma laha walwal dun jaban.Xirmada jeermis-dilaha ayaa la furi karaa oo si fudud ayaa loo isticmaali karaa.
Tilmaamaha tolida oo dhameystiran
Qodobbada buluugga ah;Taabo;Buluug, midabka dabiiciga ah midabka interweave;Iyadoo irbadda;Waxaa jira noocyo badan oo tolmo ah oo aan lahayn cirbado, dhererka duntu wuxuu u dhexeeyaa 45cm ilaa 90cm.Dhererka tolida ee gaarka ah ayaa sidoo kale lagu habeyn karaa iyadoo loo eegayo shuruudaha qalliinka.
Tolmo
Ka samaysan tayo sare leh oo adag oo adag oo laga keeno birta, irbaddu waa fiiqan tahay, dusha cirbaddu waa siman tahay, fududahay in la dhex geliyo nudaha, wax dhaawac ah uma geysan unugyada marka la tolaynayo.
Baaxadda codsiga
Alaabtan waxaa si weyn loogu isticmaali karaa dumarka, dhalmada, qalliinka, qalliinka balaastikada, kaadi mareenka, cudurrada carruurta, stomatology, otolaryngology, ophthalmology iyo qalliinnada kale iyo intradermal tollida jilicsan ee unugyada.
Sutures-ka ayaa hoos u dhacaya oo nuugaya jidhka bini'aadamka, markaa muddada bogsashada boogaha ayaa ka dheer wareegga nuugista ee alaabta.
Alaabtani waxay leedahay sifooyin bayooloji oo wanaagsan, dhakhaatiirtu waa inay ogaadaan khatarta xasaasiyadda ee suurtogalka ah ee biomaterials marka la isticmaalayo.Ilaa hadda lama helin falcelin xun
Ha ku celin bakteeriyada dabka iyo jeermiska tolida.
