EZIPHUMA ZESITOKHI SOKUFAKA KAMAZINYO YE-TITANIUM
Izimila zamazinyo ze-Titanium zinikeza izinhlobonhlobo zezici ezizenza zibe yisinqumo esihle kakhulu sokushintsha amazinyo angekho. Okokuqala, i-titanium i-biocompatible kakhulu, okusho ukuthi ihlangana kahle nezicubu zamathambo omuntu. Lokhu kuvumelana kwe-biocompatibility kunciphisa ubungozi bokwenqatshwa ngumzimba futhi kukhuthaza i-osseointegration, lapho ukufakwa kuhlangana nethambo elizungezile, kunikeze isisekelo esizinzile sezinyo elingena esikhundleni.
Ukwengeza, izimila zamazinyo ze-titanium ziqinile futhi zilula. Ibanga lesi-4 le-titanium emsulwa kwezohwebo (cpTi) ivamise ukusetshenziselwa izimila zamazinyo ngenxa yesilinganiso sayo samandla nesisindo esikhethekile. Lokhu kuvumela isigxivizo ukuthi simelane namandla okuluma asetshenziswa emlonyeni ngaphandle kokuphuka noma ukonakalisa ubuqotho baso besakhiwo. Imvelo engasindi ye-titanium nayo inomthelela enduduzo yesiguli ngesikhathi nangemva kwenqubo yokufakelwa.
Esinye isici esibalulekile sokufakelwa kwamazinyo e-titanium kanye nemikhiqizo yangokwezifiso ye-titanium ukumelana nokugqwala. I-Titanium imelana ngokwemvelo nokugqwala oketshezini lomzimba, iqinisekisa ukusebenza kwesikhathi eside kanye nokuvumelana kwezinto eziphilayo kokufakelwa. Lokhu kumelana nokugqwala kusiza ekuvimbeleni ukuwohloka kokufakelwa ngokuhamba kwesikhathi, kube nomthelela ekuphileni kwayo isikhathi eside nokuthembeka njengesixazululo sokubuyisela izinyo.
AMABANGA ESITOKHI SOKUFAKA KAMAZINYO TITANIUM
Izimila zamazinyo ze-Titanium zitholakala emabangeni ahlukahlukene, ngalinye linikeza izakhiwo nezici ezihlukile. Ibanga lesi-4 le-titanium emsulwa kwezohwebo (cpTi) ingelinye lamabanga asetshenziswa kakhulu ekufakweni kwamazinyo ngenxa yebhalansi yawo ephezulu yamandla kanye nokuhambelana kwezinto eziphilayo. Leli banga le-titanium lifaneleka kahle ukumelana nokucindezeleka kwemishini kanye nemithwalo etholwa endaweni yomlomo kuyilapho ikhuthaza ukuhlanganiswa kwe-osseo nethambo elizungezile.
Ngaphezu kwe-titanium emsulwa yokuthengisa, izimila ze-titanium alloy nazo zingasetshenziswa kwezinye izimo. Ama-alloys e-Titanium afana ne-Ti-6Al-4V (titanium-6% aluminium-4% vanadium) anikezela ngezakhiwo ezithuthukisiwe zemishini uma kuqhathaniswa ne-titanium emsulwa, okuwenza afanelekele izinhlelo zokusebenza lapho kudingeka khona amandla aphezulu. Kodwa-ke, i-biocompatibility ye-titanium alloys ingase ihluke kuye ngokuthi ibunjwe kanjani, ngakho-ke kubalulekile ukuthintana nochwepheshe wamazinyo ukuze unqume ukuthi iyiphi impahla yokufakelwa efaneleke kakhulu yecala ngalinye.
UNGATHENGA KANJANI ISIFAKALO SAMAZINYO WE-TITANIUM NGESIZWE NGEBUNINGI
Ukuthenga izimila zamazinyo ze-titanium zangokwezifiso ngobuningi kudinga ukucatshangelwa ngokucophelela nokuhlela ukuze kuqinisekiswe ikhwalithi, ukwethembeka, kanye nokusebenza kahle kwezindleko. Okokuqala, kubalulekile ukucwaninga nokuhlonza abakhiqizi abahloniphekile noma abasabalalisi bezimila zamazinyo abaziwa ngokukhiqiza imikhiqizo yekhwalithi ephezulu ehlangabezana namazinga emboni kanye nezidingo zokulawula.
Uma abahlinzeki abangaba abahlinzeki bempahla sebehlonziwe, kuyatuseka ukuthi ucele amasampula okufakelwa kwamazinyo e-titanium ukuze ahlolwe futhi ahlolwe. Lokhu kukuvumela ukuthi uhlole ikhwalithi, ukufaneleka, nokuhambisana kwezimila nezidingo zakho ezithile kanye nezidingo zesiguli.
Lapho uxoxisana ngokuthengwa kwenqwaba yezimila zamazinyo ze-titanium ngokwezifiso, cabangela izici ezifana namanani, izaphulelo zevolumu, izikhathi zokulethwa, kanye nokufakwa kwewaranti. Sungula iziteshi zokuxhumana ezicacile nomphakeli ukuze ubhekane nanoma yikuphi ukukhathazeka noma imibuzo ephathelene nenqubo yoku-oda, imininingwane yomkhiqizo, noma ukwesekwa kwangemuva kokuthengisa.
Ngaphezu kwalokho, qinisekisa ukuthi umphakeli uthobela izindinganiso ezifanele zokulawula kanye nezitifiketi ezilawula ukwenziwa nokusatshalaliswa kwemishini yezokwelapha, njengesitifiketi se-ISO 13485 kanye nokugunyazwa kwe-FDA. Lokhu kusiza ukunciphisa ubungozi bokuthola imikhiqizo esezingeni eliphansi noma engahambisani futhi kuqinisekisa ukuphepha nokwaneliseka kwesiguli.
Ngokulandela lezi zinyathelo nokusebenzisana eduze nabahlinzeki abathembekile, ungakwazi ukwenza lula inqubo yokuthenga futhi uvikele ukunikezwa okuthembekile kwezimila zamazinyo ze-titanium ngokwezifiso ukuze uhlangabezane nezidingo zomsebenzi wakho noma umtholampilo wamazinyo.
