Fayafai Titanium na Likita don Aikace-aikacen Haƙori - XINNUO

A China, 1 daga cikin 4titanium likitaimplants ya zo daga Xinnuo. A yau, muna gabatar da fayafan mu na titanium, babban abu a aikace-aikacen hakori.

Bayanin Samfurin

Nau'o'i: Akwai shi a cikin tsarin zagaye da murabba'i.

Materials: Pure titanium &titanium alloy.

Matsakaicin ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai: Disc Zagaye: Ø98mm, kauri 10-25mm.

Square Disc: 140 × 150mm, kauri 10-25mm.

Hakora titanium alloy fayafai sun zama ainihin kayan aiki a fagen gyaran baka na zamani saboda kyakkyawan aikinsu. Wannan gami na musamman an yi shi da titanium mai tsafta da aluminium, vanadium da sauran abubuwa a cikin daidaitaccen rabo, yana nuna fa'idodin da ba za a iya maye gurbinsu ba a cikin haɓakar ƙwayoyin cuta, ƙarfin injina da juriya na lalata.

Babban abin da ya fi shahara shi ne kusancin yanayin yanayin halittarsa. Fim ɗin oxide mai yawa zai fito kwatsam a saman alloy ɗin titanium, wanda ke sa naman ɗan adam ya kusan karewa daga ƙi. Wannan fasalin yana rage haɗarin kumburi a kusa da abubuwan da aka saka. Bayanai na asibiti sun nuna cewa shekaru goma na rayuwa na tsawon shekaru goma na abubuwan da aka sanya a jikin titanium na iya kaiwa sama da kashi 95%, wanda ya zarce na gargajiya na cobalt-chromium gami.

Dangane da kaddarorin injiniyoyi, gami da titanium suna nuna ƙimar ƙarfi-zuwa nauyi mai ban mamaki. Yawancin shine kawai 60% na na karfe, amma ƙarfin juzu'i zai iya kaiwa fiye da 900MPa, kuma maɗaukaki na roba yana kusa da naman kasusuwa na halitta. Wannan fasalin yana guje wa tasirin "kariyar damuwa". Zane mai nau'in diski ya dace musamman don yin abubuwan dasa shuki, wanda zai iya tarwatsa ƙarfin cizon daidai gwargwado kuma ya hana haɓakar kashi. Madaidaicin fasahar injin CNC na iya sarrafa shi zuwa tsarin 0.3mm mai tsananin bakin ciki yayin da yake riƙe kyakkyawan juriya na lalacewa.

Juriya na lalata shima yayi fice. A cikin hadadden mahallin electrolyte na yau, yawan lalatarsa ​​na shekara bai kai 0.001mm ba, wanda ya fi bakin karfe kyau. Bayan anodizing, saman zai iya samar da launuka masu tsangwama, wanda ya dace don ganewa da matsayi a lokacin tiyata kuma zai iya inganta kayan ado.

Bai kamata a yi watsi da fa'idodin fasahar sarrafawa ba. Kyakkyawan filastik da ƙarancin ƙarancin thermal na titanium gami yana ba da damar sarrafa shi ta hanyar ingantattun fasahohin ƙirƙira irin su yankan Laser da machining electrospark. Tsarin CAD/CAM na zamani na iya sarrafa shi zuwa tsarin microporous tare da madaidaicin 50μm. Wannan fili mai ƙyalli yana haɓaka abin da aka makala osteoblast kuma yana haɓaka saurin haɗin kashi da kashi 40%.

Har ila yau, kayan yana da kyakkyawar dacewa da hoto. Kusan babu kayan tarihi a lokacin gwajin CT, kuma babu wani tsangwama na maganadisu a cikin yanayin MRI, yana ba da ingantaccen tushen hoto don kimantawa bayan aiki. Yana da kyau a faɗi cewa ƙimar haɓakar haɓakar thermal ɗin ta ya dace sosai tare da enamel na halitta, wanda ke guje wa microleakage na maidowa da canje-canjen zafin jiki ya haifar.

Tare da aikace-aikacen fasahar bugu na 3D, fayafai na alloy na titanium yanzu na iya samar da abubuwan da aka keɓance na musamman tare da sifofin trabecular na bionic. Wannan sabon ƙira yana ƙara kwanciyar hankali na farko da kashi 30% kuma yana rage lokacin warkarwa zuwa makonni 3-4. Halayen kariyar muhalli kuma sun yi fice. Ana iya sake yin amfani da shi 100% kuma ya dace da manufar ci gaba mai dorewa na magungunan zamani.
