Cov ntaub ntawv tsim nyog rau biocompatibility: Kev siv kho mob ntawm cov hlau 3D luam ntawv cov ntaub ntawv nyob ntawm lawv cov biocompatibility muaj zog los lav tias lawv tsis cuam tshuam rau tib neeg lub cev implantation. Feem ntau siv cov ntaub ntawv hlau uas ua tau raws li cov qauv hauv lub tebchaws, xws li GB/T 13810-2007, "Titanium thiab Titanium Alloy Processing Materials for Surgical Implants," thiab YY/T 0966-2014, "Surgery Implant Metal Materials: Pure Tantalum}," yog titanium grade titanium 6. tantalum, thiab kev kho mob-qib nickel-titanium alloys.
Kev tshuaj xyuas ntawm cov khoom zoo: Hlau hmoov zoo tswj yog qhov tseem ceeb, yog li nws yog ib qho tseem ceeb uas yuav tsum tau txheeb xyuas lawv los ntawm cov yam ntxwv xws li roundness, sphericity, flowability, kais ntom, thiab bulk ntom thiab paub meej tias lawv lub cev thiab tshuaj lom neeg cov yam ntxwv txaus siab rau cov txheej txheem ntawm kev tsim khoom siv kho mob. Cov neeg tsim khoom ntawm cov khoom siv rov ua dua tshiab yuav tsum piav qhia thiab tshawb xyuas cov hmoov sib tov, xyuas kom meej tias qhov chaw luam ntawv tsis cuam tshuam rau cov hmoov, ua kom pom tias cov txheej txheem ruaj khov thiab siv tau rau kev kho mob, thiab tshuaj xyuas seb cov hmoov rov ua dua tshiab yuav cuam tshuam rau cov txheej txheem luam ntawv thiab cov txiaj ntsig raws li cov xwm txheej no. Tsis tas li ntawd, peb txwv tsis pub siv cov khoom siv hmoov siv dua.
Kev tsim cov hlau 3D- cov khoom siv kho mob luam tawm yuav tsum siv cov khoom siv ntsuas qhov kawg (FEA) thiab kev sim hauv computer kom paub meej cov qauv thiab lub hom phiaj ntawm kev tsim. Cov txheej txheem no tso cai rau kev txheeb xyuas ntxov ntawm qhov ua tau tsim teeb meem, suav nrog kev ntxhov siab, deformation, thiab lwm yam, thiab lawv qhov kev ua kom zoo dua los lav qhov kev cia siab thiab kev nyab xeeb ntawm cov khoom hauv kev siv tau zoo.
Siv cov txheej txheem tsim: Siv CAD software yuav pab kom ntseeg tau tias tus qauv tsim tsis muaj qhov tsis zoo, suav nrog cov ces kaum ntse, cov phab ntsa nyias, lossis kev sib txuas tsis raug. Kev tsim qauv yuav tsum ua raws li cov qauv kev tswj hwm zoo, suav nrog ISO 13485. Thaum tsim orthopedic implants, piv txwv li, mechanical compatibility thiab biocompatibility nrog cov ntaub so ntswg nyob ib puag ncig yuav tsum tau muab kev xav zoo los tiv thaiv kev cog qoob loo los yog kev mob tshwm sim los ntawm kev tsim tsis zoo.
Txhim khu kev tswj ib puag ncig: Kev tswj xyuas qhov kub thiab txias, av noo, thiab kev tswj kom huv yog qhov tseem ceeb hauv kev luam ntawv. Piv txwv li, kev hloov pauv ntawm qhov kub thiab av noo tuaj yeem cuam tshuam rau kev ua haujlwm thiab kev luam ntawv zoo ntawm cov hmoov hlau, uas tuaj yeem ua rau txo qis qhov tseeb thiab cov khoom siv tshuab ntawm cov khoom kawg. Kev tswj nruj ntawm qhov chaw luam ntawv tus yam ntxwv yog li qhov tseem ceeb los lav tias lawv poob rau hauv qhov tsim nyog.
Cov cuab yeej calibration thiab parameter qhov tseem ceeb: Xyuas kom meej tias lub tshuab luam ntawv qhov kev teeb tsa thiab ntsuas ntsuas yog qhov ua txhaum - dawb. Ntau cov ntaub ntawv hlau thiab cov ntaub ntawv cov khoom hu rau ntau qhov chaw luam ntawv, suav nrog lub zog laser, scanning ceev, txheej thickness, thiab lwm yam. Zoo meej parameter nqis pab xyuas kom zoo sib xws thiab zoo ntawm cov khoom luam tawm.
nruj tshaj tawm- txheej txheem txheej txheem: Rau kev tshaj tawm- ua haujlwm- uas yog, tshem tawm, ntxuav, tshuaj tua kab mob, thiab ua kom tsis muaj menyuam- ua raws li cov chaw tsim khoom pom zoo. Debulking tuaj yeem pab kom tsis txhob muaj cov npoo ntse ua rau cov ntaub so ntswg nyob ze; kev ntxuav tuaj yeem pab tshem tawm cov kab mob thiab cov khoom seem; sterilizing thiab tshuaj tua kab mob tuaj yeem pab tiv thaiv kab mob. Rau orthopedic implants, piv txwv li, sterilizing thiab ntxuav kom huv si guarantees lawv sterility.
Kev tswj kom zoo: lub zog tensile, compressive zog, thiab kev qaug zog kuaj, ntawm lwm yam kev ntsuam xyuas, yuav pab tau koj kom paub tseeb tias cov khoom muaj peev xwm daws tau qhov kev xav ntawm physiological stresses. Concurrent nrog cov txheej txheem no yog kuaj biocompatibility npog cytotoxicity, sensitisation, irritation, caj ces toxicity, mob toxicity, subchronic toxicity, thiab implant testing. Rau cov cuab yeej hlau cog rau hauv tib neeg lub cev, piv txwv li, kev kuaj cytotoxicity yuav tsum tau siv los ntsuas lawv cov teebmeem ntawm cov hlwb kom lav tias lawv tsis ua puas tsuaj lossis tua lawv.
Cov Cai Kho Mob Cov Cai: Ua raws li cov qauv kev kho mob hauv tebchaws thiab thoob ntiaj teb, suav nrog CE daim ntawv pov thawj hauv European Union thiab FDA hauv Tebchaws Meskas. Cov qauv nruj rau kev nyab xeeb, kev ua tau zoo, thiab kev tswj xyuas zoo ntawm cov khoom siv kho mob muaj ntau nyob rau hauv cov cai no. Piv txwv li, hlau 3D- luam tawm cov khoom kho mob muag hauv EU lag luam yuav tsum tau txais daim ntawv pov thawj CE los qhia tias lawv ua raws li EU txoj cai lij choj.
Cov txheej txheem kev lag luam: Tsim thiab ua raws li cov qauv kev lag luam uas tsim nyog, suav nrog cov khoom tsim nyog, cov qauv kev ua tau zoo ntawm cov khoom, cov txheej txheem biocompatibility, thiab lwm yam. Txhawm rau lav lawv qhov zoo thiab kev nyab xeeb, cov hlau 3D luam tawm orthopedic implants yuav tsum, piv txwv li, ua raws li cov txheej txheem kev ua tau zoo thiab cov txheej txheem biocompatibility.
Txhawm rau tsim kom muaj kev tswj hwm zoo, xav txog kev lees paub hauv ISO 13485. Muaj tag nrho cov cuab yeej kho mob tsim, kev tsim kho, tsim khoom, kev teeb tsa, thiab cov txheej txheem kev pabcuam, daim ntawv pov thawj no yog tus qauv thoob ntiaj teb rau kev tswj hwm kev ua haujlwm zoo hauv cov khoom siv kho mob. Tsim kom muaj kev tswj xyuas zoo pab kom lav qhov traceability thiab controllability ntawm cov txheej txheem tsim khoom, yog li txhim kho qhov kev cia siab ntawm cov khoom.
Cov ntaub ntawv thiab taug qab: Sau tag nrho cov theem thiab kev txiav txim siab tau ua thaum lub sijhawm tsim thiab tsim cov txheej txheem, suav nrog cov neeg muab khoom, cov txheej txheem ua haujlwm, kuaj pom, thiab kev hloov kho. Kev tuav pov hwm traceability tau lees paub tias txhua yam khoom thiab cov khoom tuaj yeem pom rov qab rau lawv cov hauv paus chiv keeb. Thaum cov teeb meem zoo tsim, piv txwv li, cov txheej txheem traceability tuaj yeem taw qhia qhov laj thawj thiab siv qhov tsim nyog.
Kev tso npe ntawm cov khoom: Sau npe thiab saib xyuas cov khoom kom lav tias lawv txaus siab rau kev nkag mus rau kev lag luam. Orthopedic kev kho mob cog tau poob rau hauv Suav teb thib peb cov khoom siv kho mob. Rau cov no, National Medical Products Administration (NMPA) qhia txog kev siv daim ntawv tso cai tsim khoom thiab cov khoom sau npe. Cov khoom zoo li no xav tau kev tshawb fawb soj ntsuam nruj thiab cov txheej txheem pom zoo; li no, kom tau txais daim ntawv pov thawj ntawm cov khoom lag luam yuav siv sij hawm - feem ntau yog peb mus rau tsib xyoos.
Kev koom tes nrog cov tub ceev xwm: Kev tswj xyuas kev sib txuas lus zoo thiab kev koom tes nrog cov thawj coj tswj hwm, kev hloov pauv raws sij hawm ntawm cov cai thiab cov qauv yuav tsum tau ua raws li kev hloov pauv thiab kev txhim kho nyob ntawm qhov xav tau. Piv txwv li, tuam txhab lag luam tuaj yeem ntsib thiab sib tham nrog cov neeg ua haujlwm tswj hwm, koom nrog hauv kev cob qhia thiab kev sib tham uas txhawb nqa los ntawm cov koom haum tswj hwm, thiab koom tes ua ntej kev txhim kho kev lag luam.
