mankhwala

Ophthalmologic opaleshoni ndi opaleshoni yochitidwa pa diso kapena mbali iliyonse ya diso.
Opaleshoni ya diso imachitidwa kaŵirikaŵiri kukonza vuto la diso, kuchotsa ng’ala kapena khansa, kapena kukonza minyewa ya maso. Cholinga chofala kwambiri cha opaleshoni ya ophthalmologic ndi kubwezeretsa kapena kukonza masomphenya.
Odwala kuyambira achichepere mpaka achikulire amakhala ndi vuto la maso lomwe limafunikira opaleshoni yamaso. Njira ziwiri zodziwika bwino ndi phacoemulsification ya ng'ala ndi ma elective refractive maopaleshoni.

Dokotala wa opareshoni, anamwino akuchipinda chopangira opaleshoni, ndi wogonetsa wogonetsa alipo kuti achite opaleshoni ya ophthalmologic. Pa maopaleshoni ambiri a maso, mankhwala ogonetsa am’deralo okha ndi amene amagwiritsidwa ntchito, ndipo wodwalayo amakhala maso koma omasuka. Dera la diso la wodwalayo limapakidwa asanamuchititse opaleshoni, ndipo zotchingira zosabala zimayikidwa pamapewa ndi kumutu. Kugunda kwa mtima ndi kuthamanga kwa magazi kumawunikidwa nthawi yonseyi. Wodwala amayenera kugona ndipo pa opaleshoni ina, makamaka opaleshoni ya refractive, amafunsidwa kuti ayang'ane kuwala kwa maikulosikopu opangira opaleshoni. A speculum imayikidwa m'diso kuti likhale lotseguka panthawi yonse ya opaleshoni.
Zida zodziwika bwino za opaleshoni ya ophthalmologic zimaphatikizapo scalpels, sutures opaleshoni, masamba, forceps, speculums, ndi lumo. Maopaleshoni ambiri a ophthalmologic tsopano amagwiritsa ntchito ma lasers, omwe amachepetsa nthawi yogwira ntchito komanso nthawi yochira.
Maopaleshoni ofuna suturing amatha kutenga maola awiri kapena atatu. Maopaleshoni ovutawa nthawi zina amafunikira luso la katswiri wa corneal kapena vitreo-retinal, ndipo amafuna kuti wodwalayo agoneke pansi pa anesthesia wamba.
Pano timalimbikitsa mankhwala angapo opangira opaleshoni ya ophthalmologic: WEGO-PGA sutures, WEGO-PGLA sutures, WEGO-Nylon Sutures ndi WEGO-Silk sutures.

WEGO-PGA Sutures imapangitsa kuti pakhale kutupa pang'ono koyambirira mu minyewa ndipo pamapeto pake imasinthidwa ndi kukula kwa minofu yolumikizana ndi ulusi. Kuwonongeka kwamphamvu kwamphamvu komanso kuyamwa kwa sutures kumachitika pogwiritsa ntchito hydrolysis, pomwe polima imatsika kukhala glycolic yomwe imatengedwa ndikuchotsedwa ndi thupi.

WEGO-PGLA suture imapangitsa kuti pakhale kutupa kochepa koyambirira kwa minofu ndipo pamapeto pake imasinthidwa ndi kukula kwa minofu yolumikizana ndi ulusi. Kuchepa kwamphamvu kwamphamvu komanso kuyamwa kwa WEGO-PGLA suture kumachitika pogwiritsa ntchito hydrolysis, pomwe copolymer imatsika kukhala glycolic ndi lactic acid zomwe pambuyo pake zimatengedwa ndikuchotsedwa ndi thupi. Kuyamwa kumayamba ngati kuchepa kwamphamvu komwe kumatsatiridwa ndi kuchepa kwa misa.

WEGO-NYLON suture imapangitsa kuti minofu iyambe kutupa, yomwe imatsatiridwa ndi kutsekeka kwapang'onopang'ono kwa suture ndi minofu yolumikizira ulusi, Ngakhale kuti polyamide simayamwa, hydrolysis ya polyamide mu vivo imatha kutayika pang'onopang'ono pakapita nthawi. .

WEGO-BRAIDED SILK suture imayambitsa kutupa koyambirira kwa minyewa, komwe kumatsatiridwa ndi kutsekeka kwapang'onopang'ono kwa suture ndi ma fibrous connective tissues. Ngakhale kuti silika samwedwa, kuwonongeka kwapang'onopang'ono kwa ulusi wa silika mu vivo kungachititse kuti pang'onopang'ono mphamvu zonse za msuti ziwonongeke pakapita nthawi.

Nawa ndondomeko zokhazikika za suture za opaleshoni ya mano:
