umkhiqizo

Ukuhlinzwa kwe-Ophthalmologic inqubo yokuhlinzwa eyenziwa esweni noma kunoma iyiphi ingxenye yeso.
Ukuhlinzwa kweso kwenzelwa njalo ukulungisa izinkinga ze-retina, ukususa ulwelwesi lwamehlo noma umdlavuza, noma ukulungisa imisipha yamehlo.Inhloso evame kakhulu yokuhlinzwa kwe-ophthalmologic ukubuyisela noma ukuthuthukisa umbono.
Iziguli kusukela kwabancane kakhulu kuye kwabadala kakhulu zinezimo zamehlo ezigunyaza ukuhlinzwa kweso.Izinqubo ezimbili ezivame kakhulu i-phacoemulsification ye-cataract kanye nokuhlinzwa okukhethiwe kwe-refractive.

Udokotela ohlinzayo, abahlengikazi basegunjini lokuhlinza, kanye nodokotela obulala izinzwa bakhona ukuze bahlinzwe amehlo.Ekuhlinzweni kwamehlo kaningi, kusetshenziswa isibulali-zinzwa sasendaweni kuphela, futhi isiguli sisuke siphapheme kodwa sikhululekile.Iso lesiguli liyakhuhlwa ngaphambi kokuhlinzwa, bese kubekwa ama-drapes angenalutho emahlombe nasekhanda.Izinga lokushaya kwenhliziyo nomfutho wegazi kuhlolwa kuyo yonke inqubo.Isiguli sidingeka ukuthi silale singanyakazi futhi ngokuhlinzwa okuthile, ikakhulukazi ukuhlinzwa kwe-refractive, sicelwa ukuba sigxile ekukhanyeni kwe-microscope yokusebenza.I-speculum ifakwa esweni ukuze ilivule ngesikhathi sokuhlinzwa.
Amathuluzi ajwayelekile okuhlinza i-ophthalmologic ahlanganisa ama-scalpel, ama-sutures okuhlinzwa, ama-blades, ama-forceps, ama-speculum, nezikele.Ukuhlinzwa okuningi kwamehlo manje kusebenzisa amalaser, anciphisa isikhathi sokusebenza kanye nesikhathi sokululama.
Ukuhlinzwa okudinga i-suturing kungathatha isikhathi esingamahora amabili kuya kwamathathu.Lokhu kuhlinzwa okuyinkimbinkimbi ngezinye izikhathi kudinga ikhono likachwepheshe we-corneal noma i-vitreo-retinal, futhi kudinga ukuthi isiguli sifakwe ngaphansi kwe-anesthesia jikelele.
Lapha sincoma imikhiqizo embalwa ye-suture efanelekile ukuhlinzwa kwe-ophthalmologic: i-WEGO-PGA sutures, i-WEGO-PGLA sutures, i-WEGO-Nylon Sutures kanye ne-WEGO-Silk sutures.

I-WEGO-PGA Sutures ivusa ukusabela okuncane kokuqala kokuvuvukala ezicutshini futhi ekugcineni ithathelwa indawo ukukhula kwezicubu ezixhumeneyo ze-fibrous.Ukuncipha okuqhubekayo kwamandla aqinile kanye nokumuncwa kwe-sutures ekugcineni kwenzeka nge-hydrolysis, lapho i-polymer incipha ibe yi-glycolic kamuva emuncwa futhi ikhishwe umzimba.

I-WEGO-PGLA suture ivusa ukusabela okuncane kokuqala kokuvuvukala ezicutshini futhi ekugcineni ithathelwa indawo ukukhula kwezicubu ezixhumeneyo ze-fibrous.Ukuncipha okuqhubekayo kwamandla okuqinile nokumuncwa kwe-WEGO-PGLA ekugcineni kwenzeka ngokusebenzisa i-hydrolysis, lapho i-copolymer yehla ibe yi-glycolic ne-lactic acid kamuva emuncwa futhi ikhishwe umzimba.Ukumuncwa kuqala njengokuncipha kwamandla okulandelwa ukuncipha kwesisindo.

I-WEGO-NYLON suture ivusa ukusabela okuncane kokuqala kokuvuvukala ezicutshini, okulandelwa ukugqunywa kancane kancane komthungo ngezicubu ezixhumene ne-fibrous, Nakuba i-polyamide ingamuncwa, i-hydrolysis eqhubekayo ye-polyamide ku-vivo ingase ibangele ukulahlekelwa kancane kancane ngokuhamba kwesikhathi kwamandla aqinile. .

I-WEGO-BRAIDED SILK suture ivusa ukusabela kokuqala kokuvuvukala ezicutshini, okulandelwa ukufakwa kancane kancane kwe-suture ngama-fibrous connective tissues.Nakuba usilika ungamuncwe, ukuwohloka okuqhubekayo kwe-proteinaceous Silk fiber ku-vivo kungase kuphumele ekulahlekelweni kancane kancane kwawo wonke amandla aqinile omthungo ngokuhamba kwesikhathi.

Nazi izicaciso ezijwayelekile ze-suture zokuhlinzwa kwamazinyo:
