"Cov Khoom Siv Kho Mob-Qib - Yog li peb muaj kev nyab xeeb, txoj cai?"
"Peb tab tom siv titanium. Nws twb tau biocompatible. Peb puas yuav tsum tau txhawj xeeb txog kev tshaj tawm -?
Qhov no yog ib qho ntawm ntau tshaj - thiab pheej hmoo - kev xav uas peb tau hnov los ntawm cov neeg siv khoom ua haujlwm nrog Hlau 3D Printing.
Ntawm daim ntawv, nws suab logical:
Titanium yog dav siv nyob rau hauv kev kho mob implants
Cov ntaub ntawv zoo li Ti6Al4V Titanium 3D Printing Parts twb tau ntawv pov thawj
Tus tsim yog lawm
Yog li ntawd tshuav dab tsi?
Nov yog qhov tseeb:
Hauv kev kho mob 3D luam ntawv, biocompatibility tsis yog txhais los ntawm cov khoom ib leeg - nws yog txhais los ntawm qhov kawg ntawm qhov chaw tom qab kev tshaj tawm - ua.
Qhov ntawd txhais tau tias txhua yam uas tshwm sim tom qab luam ntawv tuaj yeem cuam tshuam ncaj qha seb koj qhov chaw puas muaj kev nyab xeeb rau tib neeg lub cev.
Cia peb taug kev los ntawm qhov no hauv txoj kev pom tseeb.
Dab tsi yog "Biocompatibility" Tiag tiag hauv Hlau 3D Printing?
Biocompatibility tsuas yog txhais tau tias:
Cov khoom siv tuaj yeem cuam tshuam nrog tib neeg lub cev yam tsis muaj kev phom sij.
Rau Hlau 3D Printing, qhov no suav nrog:
Tsis muaj tshuaj lom
Tsis pub dhau ion tso tawm
Kev sib raug zoo nrog cov ntaub so ntswg (xws li pob txha loj hlob)
Tsis ntev - mob ntev
Lub ntsiab lus tseem ceeb:
Txawm hais tias cov khoom siv raw muaj kev nyab xeeb, qhov chaw saum npoo av tom qab kev tshaj tawm -kev txiav txim siab:
li cas cell txuas
Cov protein sib cuam tshuam li cas
lub cev teb li cas
Hauv lwm lo lus:
Khoom siv=tej zaum muaj kev nyab xeeb
Tshaj tawm -kev ua haujlwm=kev nyab xeeb tiag tiag
Yog vim li cas Post-Kev ua haujlwm muaj qhov cuam tshuam loj rau Biocompatibility
1. Nto Roughness ncaj qha cuam tshuam rau Cell Cwj Pwm
Tom qab luam ntawv, cov khoom hlau feem ntau yog:
ntxhib
ib nrab fused
npog nrog xoob hais
Kev tshawb fawb qhia tias:
Kev kho deg zoo li sandblasting lossis polishing tuaj yeem txhim kho kev cog lus ruaj khov thiab kev sib txuas ntawm pob txha
Vim li cas qhov no tseem ceeb:
Nyuaj dhau → kab mob txuas txaus ntshai
Ntxim qab heev → tsis zoo cell adhesion
Qhov chaw sab xis=cov lus teb lom neeg zoo dua
2. Cov hmoov seem thiab cov khoom tsis huv yog qhov pheej hmoo zais
Hauv cov txheej txheem xws li SLM / DMLS, feem ntau muaj:
daig hmoov
hlau khib nyiab
chemical residues
Yog tsis tau ntxuav kom zoo:
cov khoom tuaj yeem tshem tawm hauv lub cev
o tuaj yeem nce ntxiv
ntaus ntawv yuav ua tsis tau raws li
Tias yog vim li cas kev tu thiab passivation yog qhov tseem ceeb tshaj tawm - cov kauj ruam ua tiav.
3. Oxide Layers thiab Surface Chemistry Matter
Titanium alloys zoo li Ti6Al4V Titanium 3D Printing Parts lawm tsim ib txheej tiv thaiv oxide.
Kev tshawb fawb qhia tias:
Cov txheej txheem oxide no txhim kho kev tiv thaiv corrosion thiab txo kev tiv thaiv kab mob
Tab sis ntawm no yog qhov catch:
Tshaj tawm - kev ua tiav tuaj yeem yog:
txhim kho txheej txheej no
los yog ua puas rau nws
Kev ua tiav tsis tiav=txo corrosion kuj=muaj peev xwm ion tso tawm
4. Tshaj tawm -Kev Ua Haujlwm cuam tshuam Ion Tso Tawm thiab Corrosion
Cov kev tshawb fawb tsis ntev los no qhia tau tias:
Cov txheej txheem thiab cov txheej txheem saum npoo cuam tshuam rau titanium ion dissolution hauv cov cog
Vim li cas qhov no tseem ceeb:
Tshaj ion tso tawm tuaj yeem ua rau muaj kab mob lom
Ntev -lub sij hawm kev nyab xeeb nyob ntawm tus cwj pwm corrosion
Kev kho deg thiab tshuaj lom neeg ncaj qha tswj qhov kev pheej hmoo no.
5. Kev kho deg cuam tshuam rau cov protein thiab kev sib cuam tshuam ntawm tes
Cov kev tshawb fawb pom zoo:
Kev kho deg sib txawv ua rau muaj kev cuam tshuam loj heev
protein adsorption
cell adhesion
cell loj hlob
Qhov no yog qhov tseem ceeb rau:
implants (pob txha integration)
cov cuab yeej phais (biological contact)
Ntsiab Lus Tshaj Tawm -Cov kauj ruam ua haujlwm uas cuam tshuam rau Biocompatibility
Yog tias koj ua haujlwm nrog lub tuam txhab hlau 3D luam ntawv, cov kauj ruam no tsis yog xaiv tau.
