I-Medical Titanium Discs Yezicelo Zamazinyo - XINNUO

E-China, 1 kwabangu-4i-titanium yezinga lezokwelaphaizimila zivela kuXinnuo. Namuhla, sethula amadiski ethu e-titanium, okubalulekile ekusetshenzisweni kwamazinyo.

Uhlolojikelele Lomkhiqizo

Izinhlobo: Itholakala ngamafomethi ayindilinga nayisikwele.

Izinto: Titanium ehlanzekile &i-titanium alloy.

Ukucaciswa Okujwayelekile: I-Round Disc: Ø98mm, ukujiya 10-25mm.

Isikwele Disc: 140×150mm, ukujiya 10-25mm.

Amadiski e-titanium alloy amazinyo asephenduke into esemqoka emkhakheni wokubuyiselwa komlomo wesimanje ngenxa yokusebenza kwawo okuhle kakhulu. Le alloy ekhethekile yenziwe nge-high-purity titanium kanye ne-aluminium, i-vanadium nezinye izakhi ngesilinganiso esinembile, ebonisa izinzuzo ezingenakuphikiswa ku-biocompatibility, amandla emishini kanye nokumelana nokugqwala.

Isici sayo esiphawuleka kakhulu i-biocompatibility yayo eseduze-ephelele. Ifilimu eliminyene le-oxide lizozenzela ngokuzenzakalelayo phezu kwe-titanium alloy, okwenza izicubu zomuntu zicishe zivikeleke ekunqatshweni. Lesi sici sinciphisa kakhulu ingozi yokuvuvukala ezungeze izimila. Idatha yomtholampilo ikhombisa ukuthi izinga lokusinda leminyaka eyishumi lokufakelwa kwe-titanium alloy lingafinyelela ngaphezu kwama-95%, lidlule kude izinto zendabuko ye-cobalt-chromium alloy.

Ngokuphathelene nezakhiwo zemishini, ama-alloys e-titanium abonisa isilinganiso esimangalisayo samandla nesisindo. Ukuminyana kungamaphesenti angama-60 kuphela ensimbi, kodwa amandla aqinile angafinyelela ngaphezu kuka-900MPa, futhi i-elastic modulus iseduze nezicubu zamathambo emvelo. Lesi sici sigwema ngempumelelo umphumela "wokuvikela ukucindezeleka". Idizayini emise okwe-disc ifaneleka ngokukhethekile ekwenzeni ama-implant abutments, angahlakaza ngokulinganayo amandla okuluma futhi avimbele ukubuyiswa kwethambo. Ubuchwepheshe bemishini be-Precision CNC bungabucubungula bube yisakhiwo esincanyana kakhulu esingu-0.3mm sibe sigcina ukumelana nokuguquguquka okuhle kakhulu.

Ukumelana nokugqwala nakho kuvelele. Esimweni esiyinkimbinkimbi se-electrolyte yamathe, izinga layo lokugqwala lonyaka lingaphansi kuka-0.001mm, elingcono kakhulu kunensimbi engagqwali. Ngemuva kokugcotshwa kwe-anodizing, indawo engaphezulu ingakha imibala egqamile yokuphazanyiswa, elungele ukuhlonzwa nokumiswa ngesikhathi sokuhlinzwa futhi ingathuthukisa ubuhle.

Izinzuzo zobuchwepheshe bokucubungula akufanele zishaywe indiva. Ipulasitiki enhle kakhulu kanye ne-thermal conductivity ephansi ye-titanium alloy iyenza ikwazi ukucutshungulwa ngobuchwepheshe bokwakha obunembayo obufana nokusika i-laser kanye ne-electrospark machining. Izinhlelo zesimanje ze-CAD/CAM zingayicubungula ibe yisakhiwo esincane esinembayo esingu-50μm. Le ndawo enezimbotshana ikhuthaza ukunamathela kwe-osteoblast futhi ikhuphule ijubane lokubopha amathambo ngo-40%.

Impahla futhi inokuhambisana okuhle kakhulu kwesithombe. Cishe awekho ama-artifact phakathi nokuhlolwa kwe-CT, futhi akukho ukuphazamiseka kazibuthe endaweni ye-MRI, okunikeza isisekelo sesithombe esicacile sokuhlolwa kwangemva kokuhlinzwa. Kuyafaneleka ukusho ukuthi i-coefficient yayo yokwandisa okushisayo ihambisana kakhulu noqweqwe lwemvelo, olugwema ngokuphumelelayo ukukhishwa kwe-microleakage yokubuyiselwa okubangelwa ukushintsha kwezinga lokushisa.

Ngokusetshenziswa kobuchwepheshe bokuphrinta be-3D, amadiski e-titanium alloy manje angakwazi ukukhiqiza izimila zomuntu siqu ezinezakhiwo ze-bionic trabecular. Lo mklamo omusha ukhulisa ukuzinza kokuqala ngo-30% futhi ufinyeza isikhathi sokuphulukisa sibe amaviki angu-3-4. Izici zokuvikela imvelo nazo zivelele. Ingaphinda isetshenziswe ngo-100% futhi ihambisana nomqondo wokuthuthuka okusimeme kwezokwelapha zesimanje.
