Hauv kev saib xyuas kev noj qab haus huv thiab kev tshawb fawb txog lub neej, kev xaiv cov ntaub ntawv ncaj qha cuam tshuam rau cov neeg mob kev nyab xeeb thiab kev kuaj mob thiab kev kho mob zoo, nrog rau kev nyab xeeb, biocompatibility, thiab mechanical stability yog lub ntsiab lus tseem ceeb. Ultra nplua titanium hlau (inch 0.01-}0.5mm) tau dhau los ua cov khoom siv zoo tshaj plaws rau high-end teb xws li cov tshuaj me me thiab cov khoom siv cog qoob loo vim muaj cov yam ntxwv zoo heev ntawm titanium alloy, ua ke nrog qhov yooj thiab precision adaptability coj los ntawm micrometer loj. Nws daim ntawv thov tus nqi raug tso tawm tsis tu ncua nrog kev kho dua tshiab ntawm kev kho mob thev naus laus zis.
1, Cov yam ntxwv tseem ceeb: Raws li qhov tseem ceeb ntawm kev kho mob
Titanium thiab titanium alloys tau dav lees paub tias yog "kev phooj ywg zoo" hlau cov ntaub ntawv, thiab ultrafine titanium xov hlau txuas ntxiv ua kom zoo dua qhov no. In the physiological environment of the human body, a dense and stable titanium dioxide oxide film can quickly form on its surface, which can effectively block the direct reaction between the titanium substrate and human tissues, prevent the release of metal ions, and fundamentally avoid tissue rejection reactions and allergy risks, meeting the needs of long-term implantation or contact with the human body.
Piv nrog rau cov khoom siv kho mob xws li cov hlau tsis muaj steel thiab cobalt chromium alloys, ultrafine titanium hlau sib xyaw ua ke muaj zog tshwj xeeb thiab zoo heev qaug zog toughness - thaum txo txoj kab uas hla mus rau qib micrometer, nws tseem tuaj yeem tuav lub zog txaus, tiv taus cov zog xws li rov khoov thiab ncab, thiab tsis yooj yim rau hnub nyoog lossis tawg hauv tib neeg lub cev. Nws lub neej qaug zog yog 3-5 zaug ntev dua li cov hlau tsis muaj steel hlau, muab kev lees paub rau cov kev pabcuam ruaj khov rau lub sijhawm ntev ntawm cov twj paj nruag thiab cov khoom cog me me.
2, Mainstream daim ntawv thov scenarios: los ntawm minimally invasive instruments mus rau orthopedic dentistry
Nyob rau hauv lub tshav pob ntawm minimally invasive phais, ultrafine titanium hlau yog lub hauv paus ntsiab lus ntawm precision instruments, lug siv nyob rau hauv cov kev taw qhia nyob ntawm tej, fixation nyob ntawm tej, micro txuas lug, thiab phais phais. Kev kuaj mob thiab kev kho mob tsawg kawg nkaus yuav tsum tau ua kom tiav hauv qhov chaw me me, xav tau cov ntaub ntawv kom muaj kev hloov pauv tau yooj yim thiab ua haujlwm. Ultra nplua titanium xov hlau nrog txoj kab uas hla ntawm 0.1-0.3mm tuaj yeem hloov kho kom yooj yim rau cov txheej txheem physiological xws li cov hlab ntsha thiab cov kab noj hniav, xa cov kev khiav hauj lwm kom raug hauv kev qhia cov ntawv siv hlau, thiab txo cov stimulation rau mucosal cov ntaub so ntswg; Thaum siv los kho cov cuab yeej sab hauv, nws cov khoom siv kho tshuab ruaj khov tuaj yeem tiv thaiv cov cuab yeej los ntawm deforming lossis tawg thaum rov siv dua, ua kom muaj kev nyab xeeb ntawm kev phais.
Cov chaw kho hniav thiab orthopedics yog cov ntawv thov tseem ceeb rau ultrafine titanium xov hlau. Hauv orthodontics, ultra- zoo titanium hlau tuaj yeem siv los ua cov xov hlau orthodontic tus kheej. Nrog zoo elastic rov qab muaj peev xwm, nws muaj peev xwm tsis tu ncua siv maj mam thiab ruaj khov orthodontic quab yuam, hloov mus rau lub dynamic txheej txheem ntawm cov hniav txav, thiab nws biocompatibility yuav zam tsis txhob muaj kev phiv xws li cov pos hniav liab, o, thiab ua xua; Hauv kev phais orthopedic tsawg kawg nkaus, Ti-6Al-4V ELI cov khoom siv ultrafine titanium hlau nrog txoj kab uas hla ntawm 0.2-0.5mm tuaj yeem siv rau micro fixation ntawm pob txha tawg, ligament kho cov pab kho, thiab lwm yam. Nws cov khoom ua tau raws li ASTM F136 thoob ntiaj teb cov qauv kev kho mob, ntau dua li cov khoom siv oxygen thiab cov khoom sib npaug. ze rau tib neeg cov pob txha cov ntaub so ntswg, uas yuav txo tau cov neeg kho tshuab mismatch ntawm implants thiab pob txha cov ntaub so ntswg.
3, Kev lees paub ua raws thiab kev ua haujlwm tau zoo: cov ntsiab lus tseem ceeb rau cov ntaub ntawv kho mob
Kev ua raws cai rau cov ntaub ntawv hauv kev kho mob yog nruj heev, thiab kev kho mob ultrafine titanium xov hlau yuav tsum nruj me ntsis ua raws li thoob ntiaj teb cov qauv thiab ntau lawm specifications. Ntawm lawv, Ti-6Al-4V ELI (ultra-low gap element) cov khoom yog qhov kev xaiv zoo tshaj plaws rau cov xwm txheej kho mob siab kawg. Ntxiv rau kev ua raws li ASTM F136 cov qauv, nws tseem yuav tsum tswj cov ntsiab lus hydrogen tsawg dua lossis sib npaug li 0.0015% thiab cov ntsiab lus nitrogen tsawg dua lossis sib npaug li 0.03%. Los ntawm lub tshuab nqus tsev melting, precision kos duab, thiab electrolytic polishing txheej txheem, qhov saum npoo ntawm cov khoom siv hlau yog ua kom tsis muaj oxide txheej, khawb, thiab impurities, nrog rau qhov chaw roughness Ra tsawg dua los yog sib npaug li 0.5 μ m, kom tsis txhob muaj kab mob los yog cov ntaub so ntswg o.
Rau cov xwm txheej sib txawv, kev kho mob ultrafine titanium hlau tseem yuav tau txais kev ua tau zoo ntawm kev ua haujlwm zoo: cov hlau siv rau kev cog qoob loo yuav raug kho qhov chaw kho kom zoo dua nws cov peev xwm sib txuas nrog cov pob txha; Cov kab xev siv rau cov khoom siv pov tseg tsawg kawg nkaus ua kom zoo rau cov txheej txheem tsim khoom thaum ua kom muaj kev ua tau zoo, ua tiav qhov sib npaug ntawm tus nqi thiab kev nyab xeeb.
4, Kev cia siab yav tom ntej: Kev kho kom haum rau cov qauv ntawm miniaturization thiab precision hauv kev kho mob thev naus laus zis
Nrog rau kev laus ntawm cov khoom siv kho mob mus rau miniaturization, raug, thiab hnav, stride raug thiab kev ua haujlwm ruaj khov ntawm cov ntaub ntawv kuj tseem xav tau, thiab daim ntawv thov teb ntawm ultrafine titanium xov hlau tau nthuav dav. Nyob rau hauv lub teb ntawm micro cog cov cuab yeej, lawv tuaj yeem siv los ua cov khoom siv cog qoob loo degradable thiab cov twj tso kua mis lub cev lub cev kom ua tau raws li kev kuaj mob thiab kev kho mob hauv lub cev; Nyob rau hauv lub tshav pob ntawm cov khoom siv kho mob hnav, ultrafine titanium hlau ua haujlwm raws li cov pob txha pob txha ntawm cov hloov pauv hloov pauv, uas tuaj yeem sib npaug biocompatibility thiab txhua yam hloov pauv tau tiag tiag - sijhawm saib xyuas cov ntaub ntawv kev noj qab haus huv.
Hauv kev xaus, ultrafine titanium hlau tau ua tiav qhov tseem ceeb ntawm kev siv tsis tau hauv kev kho mob thiab kev tshawb fawb txog kev ua neej vim nws qhov kev ua tau zoo thiab ua tau zoo heev. Nyob rau hauv lub neej yav tom ntej, nrog rau kev kho dua tshiab ntawm cov khoom siv technology thiab iteration ntawm kev kho mob xav tau kev pab, nws yuav ua txhaum los ntawm daim ntawv thov ciam teb nyob rau hauv ntau siab -kuaj ntsuam xyuas thiab kev kho mob scenarios, muab cov ntaub ntawv tseem ceeb txhawb rau precision tshuaj thiab kho neeg mob.
