Ubuvuzi bwa PGA hamwe ninshinge zigoramye hamwe ninshinge zijugunywa
Polyglactinesuture igizwe nududodo twa suture twahujwe nurushinge rwa suture.Urushinge rwa suture rukozwe mubyuma byujuje ubuziranenge ibyuma byubuvuzi kandi bifatanye neza nu mugozi wa suture.Suture (inshinge y'urushinge) ikoreshwa mugushushanya imyenda yoroshye ónumubiri wumuntu.Polyglactine ni synthique ishobora kwinjizwa na multifiliment sterile yo kubaga igizwe na glycolike (90%) na L- Lactide (10%) ikora copolymer.Urudodo rwa polyglactine rudodo kandi rusizwe hamwe na calcium sterateand na Polyglactine 370. Urudodo rwa suture hamwe na coatingcan byinjizwa numubiri wumuntu binyuze muri hydrolysis idafite ingaruka mbi kumubiri wumuntu.Polyglactine suturesfulfil ibisabwa byose USP hamwe na Pharmacopoeia yu Burayi kuri sterile, sintetike ikurura suture.

Ubuvuzi bwa PGLA
Hamwe nogutezimbere ibintu bigoye hamwe nubuhanga bwa tekinike yo kubaga abantu imbere, suture yinjira ikoreshwa ntigomba kugira imbaraga runaka gusa, ahubwo irashobora no kwangirika buhoro buhoro no kwinjirira mumubiri hamwe no gukira igikomere.Poly (Ethyl lactide - lactide) (PGLA) nimwe mubikoresho byingirakamaro kandi byizewe biomedical medicine, bishobora gukoreshwa mugukora suture nziza.Tianhe BRAND PGLA yubuvuzi yakira suture ikozwe muri copolymerisation ya Ethyl lactide na lactide ukurikije igipimo gikenewe, binyuze mukuzunguruka, kurambura, kuboha, gutwikira nibindi bikorwa.Iyi suture ishobora kwinjizwa ifite biocompatibilité nziza, nta reaction igaragara yumubiri wumuntu, imbaraga nyinshi, kurambura mu rugero, kutagira uburozi, kutarakara, guhinduka no kwangirika kwiza (ibicuruzwa bitesha agaciro ni dioxyde de carbone namazi).
Ibikoresho fatizo byibicuruzwa bitumizwa mu mahanga (Ethyl lactide - lactide), bizunguruka kandi bikozwe na sosiyete yacu.Ibintu bya hydrolyzed yibicuruzwa birashobora kwinjizwa numubiri wumuntu, kandi reaction ya tissue iba mike.Nibicuruzwa byazamuwe kugirango tunoze ububabare bwibikorwa.
· Imbaraga zikomeye
Imbaraga zingutu zirashobora kugumaho muminsi irenze 5-7 kugirango ikire ibikomere, kandi imbaraga zo gupfundika ziri hejuru cyane kurenza urudodo rwinda, zitanga umutekano kubarwayi.· Biocompatibilité nziza
Nta gukangurira umubiri w'umuntu, nta cytotoxicitike, nta burozi bwa genetike, nta gutera imbaraga, kandi bishobora guteza imbere imikurire ya fibrous ihuza imbere.- Kwinjira kwizewe
Ibicuruzwa birashobora kwinjizwa numubiri wumuntu binyuze muri hydrolysis.Absorption itangira nyuma yiminsi 15 nyuma yo guterwa, hamwe ninshi iyinjizwa nyuma yiminsi 30 hanyuma ikinjira neza nyuma yiminsi 60-90.- Biroroshye gukora
Ibicuruzwa biroroshye, wumve ari byiza, byoroshye mugihe ukoresheje, ishyirahamwe rito gukurura, byoroshye ipfundo, rihamye, ntamutwe wacitse.Porogaramu idasembuye irashobora gufungurwa no gukoreshwa byoroshye.
Ibisobanuro byuzuye byo kudoda
Ingingo z'ubururu;Gukoraho;Ibara ry'ubururu, kamere karemano;Urushinge;Hariho ubwoko bwinshi bwubudozi butagira inshinge, hamwe nuburebure bwurudodo kuva kuri 45cm kugeza 90cm.Uburebure bwihariye bwa suture burashobora kandi gutegurwa ukurikije ibisabwa kwa muganga.
Ubudozi
Ikozwe mubwiza buhanitse kandi bukomeye bwo gutumiza ibyuma bitumizwa mu mahanga, urushinge rurakaze, hejuru y'urushinge ruroroshye, byoroshye kwinjira mu ngingo, nta byangiza imyenda iyo idoda.
Ingano yo gusaba
Iki gicuruzwa kirashobora gukoreshwa cyane mubagore, kubyara, kubaga, kubaga plastique, urologiya, kuvura abana, stomatologiya, otolaryngologiya, amaso yubuvuzi nibindi bikorwa hamwe na suture yimbere yoroheje.
Ubudodo bwononekaye kandi bwinjizwa numubiri wumuntu, bityo igihe cyo gukira ibikomere ni kirekire kuruta kwinjirira ibicuruzwa.
Iki gicuruzwa gifite imiterere-karemano y’ibinyabuzima, abaganga bagomba kumenya ingaruka zishobora guterwa na allergique ziterwa na biomateriali mugihe bayikoresheje.Nta ngaruka mbi zabonetse kugeza ubu.
Ntugasubiremo bagiteri yumuriro no kwanduza suture.
