Ⅰ.Three Cov kev mob kho mob loj ntawm kev kho mob titanium alloys
1. Biocompatibility: uas "coexist kev thaj yeeb" nrog tib neeg lub cev
Cov tau zoo dua: Tib neeg lub cev muaj yuav luag tsis muaj kev tsis lees txim
Cov ntaub ntawv sau cia: Raws li kev kawm ntawm phau ntawv xov xwm "Biomabsiss kev tshawb fawb", cov ntaub ntawv sib kis ntawm titanium alloys tau mus txog 98.2%, deb tshaj stainless hlau (85%) thiab lobalty alloys (90%)
Tus Neeg Mob Cov Neeg Mob: Cov ntaub ntawv los ntawm Shanghai Thib Rau Tsev Kho Mob uas pom tias tus kab mob postperative ntawm cov neeg mob uas siv titanium alloys tau txo los ntawm 67%
"Nws yog zoo li tus 'Tij Laug Tij Laug' ntawm cov pob txha, thiab cov tib neeg lub cev tsis muaj zog tuaj yeem paub txog nws ua txawv teb chaws." -- Xib fwb Wang Jianhua, ib tug orthopedic kws tshaj lij
2. Corrosion Kuj: ib lub tshuab kaw khoom "perpetual mapetual" hauv lub cev uas tsis xeb rau 30 xyoo
Kuaj: Hauv cov ntsev daws simulating tib neeg lub cev ib puag ncig, tus nqi corrosion, tus nqi ntawm titanium alloy hauv 200 xyoo tsuas yog 0.003mm (daim ntawv qhia los ntawm cov ntaub ntawv ntsuas ntawm Peking University)
Pov xav: Lub Koom Haum British Orthopedic Association pom tias 15-} xyoo ciaj sia ntawm titanium alloy cov pob qij txha yog siab li 95%
3. Cov neeg kho tshuab hloov tau: cov pob qij txha uas tuaj yeem "seev cev"
| Cov yam ntxwv | Titanium alloy qhov tseem ceeb | Tib neeg cov pob txha muaj nuj nqis | Sib Tw Degree |
| Elastic modulus | 110 GPA | 10-30 GPA | ze tshaj |
| Qaug zog muaj zog | 500 MPa | 150 MPA | 3 Lub Sij Hawm Kev Ruaj Ntseg |
Technical technoveration insov kev:
3D luam tawm customized poj niam tus qauv tso cai rau pob txha hlwb kom loj hlob mus rau hlau
Dynamic ntaub ntawv kev ntsuam xyuas pom tias titanium alloy pob qij txha tuaj yeem tiv taus 10, {{1} gait} gait hyclo
Ⅱ. Kev kho mob kho mob uas tau pom los ntawm cov pov thawj digital
Kev sib piv ntawm kev phais cov nqi (2023 International Orteration Federation)
Titanium alloy pob qij txha: 97.8%
Cov ntaub ntawv ib txwm muaj: 89.4%
Rov qab lub sij hawm manestones
Lub sij hawm tau tawm ntawm lub txaj: 3 hnub (titanium alloy) vs 7 hnub (ib txwm muaj)
Phaus tag nrho-bearing taug kev: 2 lub lis piam vs 6 lub lis piam
Ⅲ. Los ntawm kev ua qauv rau tus kheej: lub ERA ntawm customized titanium alloy pob qij txha
5 kauj ruam los tsim cov pob qij txha tshwj xeeb (txheej txheem ntawm kev ua lag luam ua haujlwm)
1.Precisise Modeling: ct scan los tsim cov qauv 3D
2.ai sib txuam: Pom zoo tsim qauv los ntawm 2000+} chaw kuaj cov tsev qiv ntawv
3.Laser cladding: luam tawm ntxeem cov qauv nrog micron-qib precision
4.BIOATTIVATION: Cov txheej txheej saum npoo nrog txheej hydroxyapatite txheej
5.Txoj Kev Ntsuas Vivo: 1 lab kev kuaj qoj ib ce ua tiav nyob rau hauv simulator
Cov xwm txheej ib txwm:
Customized hypermobility sib koom tes rau cov seev cev
Tsim kev thauj khoom-cov kabmob qauv rau cov neeg mob rog
Cov lus teb muaj cai rau kev ua xyem xyav
Q: Cov titanium alloy ua rau cov tshuaj tsis haum?
A: Kev ua xua ntawm cov ntshiab titanium tsuas yog 0. 6% (cov ntaub ntawv tiv thaiv "chromium alloy (15%)
Q: Kuv puas yuav tsum tau muab nws tshem tawm rau MRI kuaj?
A: Kev kho mob titanium alloy yog cov khoom siv tsis sib nqus nrog MRI hauv qab no 3. {} T
