ibicuruzwa

Kubaga amaso ni uburyo bwo kubaga bukorwa ku jisho cyangwa igice icyo ari cyo cyose cy'ijisho.
Kubaga ijisho bikorwa buri gihe kugirango bikosore inenge, gukuramo cataracte cyangwa kanseri, cyangwa gusana imitsi y'amaso. Intego isanzwe yo kubaga amaso ni ukugarura cyangwa kunoza icyerekezo.
Abarwayi kuva bato cyane kugeza bakuze bafite imiterere ya ocular itanga kubaga amaso. Babiri muburyo bukunze kugaragara ni phacoemulisifike ya cataracte no kubagwa guhitamo.

Umuganga ubaga, abaforomo bo mu cyumba cyo kubaga, hamwe na anesthesiologue bahari kugira ngo babagwa amaso. Kubagwa amaso menshi, hakoreshwa gusa anesthetic yaho, kandi umurwayi arakangutse ariko araruhutse. Agace k'amaso k'umurwayi karasuzumwa mbere yo kubagwa, kandi drape sterile ishyirwa ku bitugu no ku mutwe. Igipimo cy'umutima n'umuvuduko w'amaraso bikurikiranwa muburyo bwose. Umurwayi asabwa kuryama atuje kandi kubagwa bimwe na bimwe, cyane cyane kubaga byanze bikunze, asabwa kwibanda ku mucyo wa microscope ikora. Igitekerezo gishyirwa mumaso kugirango gifungure mugihe cyose cyo kubagwa.
Ibikoresho bisanzwe byo kubaga amaso harimo scalpels, suture yo kubaga, ibyuma, imbaraga, spulum, na kasi. Kubaga amaso menshi ubu bakoresha laseri, bigabanya igihe cyo gukora kimwe nigihe cyo gukira.
Kubaga bisaba kudoda birashobora gufata igihe cyamasaha abiri cyangwa atatu. Kubaga bigoye rimwe na rimwe bisaba ubuhanga bwinzobere ya corneal cyangwa vitreo-retinal, kandi bigasaba umurwayi gushyirwaho anesthesia rusange.
Hano turasaba ibicuruzwa byinshi bidoda bikwiranye no kubaga amaso: suture ya WEGO-PGA, suture ya WEGO-PGLA, Suture ya WEGO-Nylon na WEGO-Silk.

WEGO-PGA Sutures itanga byibuze intangiriro yo gutwika mumyanya hanyuma amaherezo igasimbuzwa no gukura kwimitsi ya fibrous ihuza. Gutakaza buhoro buhoro imbaraga zingutu hamwe no kwinjiza suture bibaho hakoreshejwe hydrolysis, aho polymer yangirika kuri glycolike igahita ikurwaho ikanakurwaho numubiri.

Suture ya WEGO-PGLA itanga intangiriro ntoya yo gutwika mumyanya hanyuma amaherezo igasimbuzwa no gukura kwimitsi ya fibrous ihuza. Gutakaza buhoro buhoro imbaraga zingirakamaro hamwe no kwinjiza suture ya WEGO-PGLA bibaho hakoreshejwe hydrolysis, aho copolymer yangirika kuri acide glycolike na lactique nyuma ikinjizwa ikanakurwaho numubiri. Absorption itangira nkigihombo cyingufu zikurikirwa no gutakaza misa.

Ubudodo bwa WEGO-NYLON butera intangiriro ntoya yo gutwika mubice, bigakurikirwa no gufunga buhoro buhoro suture hamwe na fibrous ihuza tissue, Mugihe polyamide idashizwemo, hydrolysis igenda itera polyamide muri vivo irashobora kuviramo gutakaza buhoro buhoro mugihe cyimbaraga zingutu. .

WEGO-BRAIDED SILK suture itanga reaction yambere yo gutwika mumyanya, igakurikirwa no gufunga buhoro buhoro suture hamwe na fibrous ihuza. Mugihe Silk idashizwemo, kwangirika gahoro gahoro ya proteineace Silk fibre muri vivo bishobora kuviramo gutakaza buhoro buhoro imbaraga zose za suture zigihe cyigihe.

Hano hari suture isanzwe yo kubaga amenyo:
