Cov ntaub ntawv twg yog cov feem ntau siv hauv cov hlau 3D luam tawm los tsim cov kev cog qoob loo orthopedic?

1, stainless hlau khoom
Stainless hlau yog ib qho ntawm cov khoom cog ua ntej no tau siv hauv tib neeg lub cev, tshwj xeeb tshaj yog 316L stainless hlau, uas yog lub luag haujlwm tseem ceeb hauv kev tsim khoom ntawm orthopedic kev cog lus. Stainless hlau muaj zoo biocompatibility, corrosion tsis kam, thiab kev siv tshuab lub zog, uas tuaj yeem ua kom tau cov kev cuam tshuam ntawm orthopedic. Ib qho ntxiv, tus nqi pheej yig pheej yig ntawm stainless hlau ua rau nws muaj nqi nyob rau hauv cov ntawv thov kev kho mob hnyav. Txawm li cas los xij, stainless hlau corrode hauv lub cev ib puag ncig, uas yuav ua rau muaj kev hem thawj mus rau lub sijhawm ntev thiab kev tiv thaiv kev tiv thaiv. Yog li ntawd, hauv cov luam tawm hlau 3D ua haujlwm, kev siv cov hlau stainless yuav tsum tau tswj hwm ntawm nws txoj kev ua tau zoo los ua kom paub meej txog kev cog lus.
2, Titanium Alloy Khoom
Titanium alloy yog ib qho ntawm cov khoom siv hlau uas feem ntau siv rau hauv kev tsim khoom ntawm Orthopedic kev cog lus. Ntawm lawv, Ti6al4V titanium alloy yog heev favored vim nws zoo biocompatibility, corrosion tsis kam, thiab kev kho tshuab zog. Elastic modulus ntawm titanium alloy los ze dua ntawm cov pob txha, uas tuaj yeem txo cov nyhuv kev ntxhov siab thiab txhawb cov pob txha kev loj hlob thiab kho kom zoo. Tsis tas li ntawd, titanium alloys tseem muaj kev sib kho zoo thiab txheej txheem, ua kom haum kev tsim kho ntawm cov qauv hlau 3D hauv. Txawm li cas los xij, titanium alloys tseem ntsib qee cov kev cov nyom, xws li cov kev tiv thaiv kev ntxhov siab thiab teeb meem kev sib xyaw ua ke. Txhawm rau hais txog cov teeb meem no, cov neeg tshawb nrhiav tau tshawb txog cov kev kho tshiab titanium muaj ntau yam thiab cov kev kho kom zoo rau kev txhim kho lawv cov kev ua haujlwm thiab pob txha sib xyaw ua ke.
Ntxiv rau Ti6al4V titanium alloy, lwm cov titanium alloys xws li ti yog maj tau siv nyob rau hauv kev tsim khoom ntawm orthopedic kev cog lus. Cov alloys muaj qis ywj siab moduli, uas tuaj yeem ua tau zoo dua cov pob txha uas tsis sib xws thiab txo kev ntxhov siab tiv thaiv cov teebmeem. Ib qho ntxiv, los ntawm kev siv cov qauv titanium thiab cov txheej txheem tsim qauv zoo li cov av melting (pbf-lb), txhawb nqa cov pob txha kev loj hlob thiab txhim kho cov pob txha sib txuas.
3, cobalt chromium alloy khoom
Cobalt Chromium Alloy yog lwm cov khoom siv feem ntau siv cov khoom siv. Nws muaj cov zoo corrosion tsis kam thiab hnav tsis kam, zoo dua rau cov hlau stainless thiab qee cov titanium alloys. Cobalt Chromium alloy kuj muaj siab tawv thiab lub zog, thiab tuaj yeem tiv thaiv loj loj thiab kev sib txhuam. Yog li ntawd, nws feem ntau yog siv los ua cov khoom siv hloov chaw rau kev tsim khoom thiab cov hniav, xws li cov pob txha ntaus nrig, cov pob txha ua pob qij txha, thiab kev cog hniav hauv caug, thiab kev cog hniav hauv caug, thiab kev cog hniav lub hauv caug. Txawm li cas los xij, tus nqi ntawm cobalt chromium alloys kuj tseem muaj siab, thiab lawv cov modastic modulus siab kuj tseem yuav ua rau muaj kev ntxhov siab. Txhawm rau ua kom pom cov teeb meem no, cov neeg tshawb xyuas tshawb xyuas cov txheej txheem kev kho kom zoo thiab cov pob txha sib xyaw ua ke muaj peev xwm ntawm kev siv cov chromium.
Cobalt Chromium Molybdenum alloy yog ib qho kev sib txawv ntawm cov cobalt Chromium alloy, uas ntxiv rau nws lub zog thiab corrosion tsis kam los ntawm kev ntxiv Molybdenum caij mus rau Alloy. Qhov no ua rau cob cov chromium molybdenum alloys kom ua tau zoo dua nyob rau hauv ib puag ncig siab, xws li Temur thiab Tibia cov khoom phais.
4, cov ntaub ntawv nthuav tawm
Ntxiv nrog rau cov ntaub ntawv hlau tsoos uas tau hais los saum toj no, cov tshuab ua hlau 3D yog tas li kawm tau cov khoom siv tshiab orthopedic. Piv txwv li, cov lag luam magnes tau nyiam ntau dua vim lawv lub zog zoo rau qhov hnyav piv, thiab cov tub ntxhais hluas cov modulus zoo ib yam li cov pob txha. Txawm li cas los xij, kev tawm tsam sai dua cov yam ntxwv ntawm cov hlau nplaum magoes hauv vivo kuj yog pose cov nyom. Cov kws tshawb nrhiav tau tshawb nrhiav seb nws tus nqi degradation kom paub meej tias kev nqus tau zoo. Zinc alloys tau muaj kev ywj siab vim lawv lub luag haujlwm tseem ceeb hauv cov pob txha me metabolism thiab cov tshuaj tua kab mob. Cov kws tshawb nrhiav tau txuas ntxiv txhim kho nws cov kev ua haujlwm zoo thiab biocompatibility, tso lub hauv paus rau nws cov ntawv thov hauv Orthopedic kev cog lus.
Ib qho ntxiv, qee cov kev ua haujlwm tshwj xeeb muaj kuj pom muaj peev xwm hauv cov 3D luam tawm orthopedic. Piv txwv li, cov duab nco alloys tuaj yeem rov qab lawv cov qauv qub raws li qhov xwm txheej tshwj xeeb, uas pab ua kom ua tiav kev hloov kho kev hloov kho thiab cov lus teb ntawm kev pom. Nano coated alloys siv Nanotechnology rau encapsulation cov ntaub ntawv ntawm cov npoo ntawm alloy los txhim kho nws biocompatibility thiab pob txha sib xyaw muaj peev xwm.
5, Cov khoom siv xaiv thiab ua kom zoo dua
Kev xaiv thiab kev ua kom zoo ntawm cov ntaub ntawv yog qhov tseem ceeb hauv kev tsim khoom lag luam ntawm cov hlau 3D luam tawm Orthopedic. Firstly, cov ntaub ntawv tsim nyog yuav tsum tau xaiv raws li cov kev cai ua haujlwm, biocompatibility yuav tsum tau, thiab cov khoom siv mechanical ntawm kev cog lus. Thib ob, nws yog qhov tsim nyog los ua kom zoo luam tawm thiab cov txheej txheem los xyuas kom meej meej tsim kho thiab ua kom zoo ntawm kev cog hniav. Ntxiv rau, nruj nruj biocompatibility ntsuas thiab kev ntsuas tshuab kev ua tau zoo ntawm kev pom yog qhov yuav tsum tau ua kom lawv muaj kev nyab xeeb thiab kev ntseeg tau.
