Qhov tseem ceeb npaum li cas yog kev tu cov kauj ruam hauv Kev Kho Mob Post-Kev ua tiav?

Lub luag haujlwm ntawm Kev Tu hauv Kev Kho Mob Post-Kev ua tiav

Kev ntxuav tshem tawm cov teeb meem seem thiab cov khoom seem thaum npaj lub ntsej muag rau cov kauj ruam tom ntej xws li passivation lossis ntim khoom. Nws tuaj yeem nco cov kab mob sib sib zog nqus hauv cov geometry nyuaj yog tias tsis ua kom raug.

Kev ntxuav kev sib cuam tshuam nrog txhua lwm yam kev tshaj tawm- cov kauj ruam ua: nws yuav tsum ua raws li kev ua haujlwm tab sis ua ntej qhov kawg passivation kom paub meej qhov huv si rau kev tsim oxide txheej. Kev ua tsis tiav feem ntau nyob twj ywm tsis pom mus txog thaum siv tshuaj kho mob, thaum cov khoom los yog cov khoom seem ua rau muaj teeb meem.

A hlau 3D luam ntawvChaw tsim tshuaj paus xa Ti-6Al-4V hip stems uas dhau tag nrho cov qauv kuaj. Cov hmoov seem nyob rau hauv trabecular channel tom qab ua rau osteolysis thiab cog loosening. Qhov no qhia txog qhov tseem ceeb ntawm SLM implant tu.

Cov kab mob dab tsi yog peb tham tiag tiag?

Residual hlau hmoov: Qhov teeb meem saum toj kawg nkaus hauv kev tsim khoom ntxiv (AM) qhov chaw, tshwj xeeb tshaj yog nyob rau hauv lattices thiab cov qauv ntxeem tau.

Cov txheej txheem tshuaj: txiav kua, polishing compounds, thiab passivation residues.

Mechanical khib nyiab: Bead blast media thiab abrasive hais.

Cov kab mob lom lom: Endotoxins thiab biofilm precursors los ntawm kev tuav.

Hla- paug: Los ntawm ntau- cov khoom tsim los yog cov khoom siv sib koom.

Ti6Al4V implant deg contamination thiab SLM kho mob ib feem endotoxin yuav tsum tau nruj tswj.

Yuav ua li cas ntxuav Fits rau hauv Daim Ntawv Qhia Tag Nrho -Ua ib ntus

Ib tug raug saw rauTi6Al4V 3D luam ntawv kho mob cog qhov chawsuav nrog: kev tshem tawm hmoov → HIP / kev kho cua sov → kev txhawb nqa tshem tawm / ua haujlwm → nto tiav → ultrasonic lossis ntau -theem tu → passivation → zaum kawg tshuaj xyuas → ntim tsis muaj menyuam.

Txoj hauj lwm ntawm kev ntxuav tseem ceeb heev. Ua ntej- ntxuav tshem cov hmoov ntau, nruab nrab ntxuav tom qab tshuab, thiab qhov kawg huv huv kom paub meej biocompatibility. Ua nws tawm ntawm qhov sib lawv liag tuaj yeem cuam tshuam cov khib nyiab lossis puas qhov chaw.

Txoj kev ntxuav siv hauv kev kho mob hlau ncej-Kev ua tiav

Ultrasonic tu: Kev lag luam workhorse rau complex geometry.

Txau ntxuav: Zoo dua rau cov khoom yooj yim.

Kev ntxuav phau ntawv: Siv ntxiv tab sis nce kev tswj hwm.

CO₂ / supercritical CO₂: Emerging zero-kev xaiv residue.

Plasma tu: Zoo heev rau qhov kawg ua kom nto.

Ntau -theem cycles: Kev ua tau zoo tshaj plaws.

Cov ntaub ntawv rooj: Kev sib piv ntawm kev ntxuav

Ultrasonic tu Ti6Al4V implants feem ntau yog lub hauv paus rau kev cai.

Vim li cas Ti6Al4V Implant Parts xav tau kev saib xyuas ntxiv

Ti-6Al-4V tsim ib txheej TiO₂ ruaj khov uas muab biocompatibility zoo heev, tab sis kev tu tsis raug tuaj yeem cuam tshuam nws. Porous lattice structures ntxiab hmoov sib sib zog nqus, thiab titanium lub zog saum npoo ua rau cov khoom ua kom muaj zog. Kev ntxuav chemistry yuav tsum txhawb nqa tom qab passivation thiab osseointegration yam tsis tau tawm hauv seem.

Ntxuav validation

Kev ua kom huv si ua pov thawj tias cov txheej txheem ua tau raws li cov qauv kev huv huv los ntawm qhov phem tshaj - kuaj cov ntaub ntawv, TOC, particle suav, thiab LAL endotoxin kuaj. Kev lees txais yuav tsum yog kev tshawb fawb-raws li thiab khi rau hauv chav kawm muaj kev pheej hmoo. Re-validation yog yuav tsum tau tom qab hloov.
