3D Printing yog npaj txhij los kho cov yas lub cev cog

Tom qab muaj kev huam yuaj ua rau ib tug poj niam muaj hnub nyoog 40 xyoo nyob rau hauv Sweden nrog mob loj heev lub taub hau lig xyoo tas los, nws tau txais 3D-printed implants ua los ntawm ib tug yas hu ua PEEK los kho nws pob txha taub hau.

Nws yog thawj zaug uas lub tsev kho mob tau tsim thiab 3D luam tawm ib qho kev cog qoob loo ntawm qhov chaw no, thiab nws tuaj yeem ua pov thawj qhov hloov pauv rau 3D luam ntawv hauv kev kho mob.

"Raws li peb paub, peb yog lub ntiaj teb thawj zaug ua 3D implants tag nrho hauv tsev kho mob, uas txhais tau hais tias cov kev cog hniav yuav hloov tau zoo rau cov neeg mob, txij thaum pib," hais tias Einar Heiberg Brandt, kws kho mob hauv Clinical Physiology. ntawm Skåne University Tsev Kho Mob, Sweden. "Qhov no yuav ua rau muaj kev phais sai dua thiab muaj teeb meem tsawg dua."

Hauv tsev kho mob 3D luam ntawv tseem nyob rau theem pib, tab sis qhia tau hais tias kev cog lus zoo, cov kws tshaj lij kev lag luam pom zoo. Txawm hais tias 3D luam ntawv tau siv nyob rau hauv kev kho mob rau ntau tshaj kaum xyoo los tsim cov titanium thiab stainless hlau implants, PEEK yas nthuav txoj hauv kev rau cov thev naus laus zis txav tawm ntawm lub khw hauv pem teb ntawm cov chaw tsim khoom siv kho mob thiab mus rau hauv chav kuaj hauv tsev kho mob thiab chaw kho mob thoob ntiaj teb.

Qhov tseeb, cov chaw kho mob sawv cev rau kev lag luam tshiab loj heev rau 3D luam ntawv. Kev kho mob ntu ntawm 3D luam ntawv kev lag luam, uas suav nrog kev kho hniav thiab 3D-luam luam tshuaj, tam sim no muaj nuj nqis ze li $ 3 nphom.

3D Printing ntawm Tsev Kho Mob

Cov tsev kawm ntawv, xws li Mayo Clinic hauv Minn. thiab VA cov tsev kho mob thoob plaws tebchaws, muaj ntau lub chaw 3D luam ntawv. Cov haujlwm muaj feem ntau yog tus neeg mob tshwj xeeb 3D-luam tawm kho mob qauv, cov cuab yeej kev cob qhia phais, thiab orthopedic braces. Txawm li cas los xij, yav tom ntej tsis deb dhau, cov tsev kho mob no yuav yog 3D luam ntawv cov neeg mob tshwj xeeb cog hauv PEEK rau txhua hom kev phais.

Siv lub tshuab luam ntawv 3D thiab PEEK filament coj cov npe ntev ntawm cov txiaj ntsig rau tsev kho mob, thaum tseem muaj teeb meem loj. Cov txheej txheem, thaum muab piv rau cov kev siv tshuaj kho mob tau tsim, uas yog machining thiab txhaj tshuaj molding, tuaj yeem ua rau ntawm qhov chaw ntawm kev saib xyuas. Qhov no txhais tau hais tias kev cog qoob loo sai dua, cov nqi qis dua, thiab kev sib koom tes zoo dua ntawm tus kws phais thiab cov kws tshaj lij tsim cov khoom cog.

Los ntawm kev siv tus neeg mob cov ntaub ntawv los ntawm kev soj ntsuam thiab X-rays, cov tsev kho mob tuaj yeem 3D luam tawm ib qho kev cog qoob loo uas haum rau qhov chaw tsis xws luag.

Cov kev tshawb fawb qhia tau hais tias cov neeg mob tshwj xeeb implants txo lub sij hawm phais, txo qis kev pheej hmoo ntawm kev kis kab mob, ua rau cov txiaj ntsig zoo dua, thiab txo qhov ntev ntawm kev nyob hauv tsev kho mob. 3D luam ntawv cov cog cog raws li qhov xav tau kuj tseem txo qis hauv tsev kho mob kom tsis txhob khaws cov khoom lag luam ntawm cov khoom cog kim heev ntawm tes.

Txawm hais tias, txog niaj hnub no, tsis muaj 3D-luam PEEK implants tsim nyob rau hauv tsev kho mob pom zoo los ntawm FDA, uas yuav sai sai no hloov.

Lub German pib tsim tshwj xeeb hauv 3D-luam PEEK pob txha taub hau cog, Kumovis, hais tias nws tab tom ua tiav cov teeb meem zaum kawg hauv txoj kev pom zoo FDA.

Miriam Haerst, co-founder thiab co-CEO ntawm Kumovis hais tias "Muaj ntau qhov kev zoo siab nyob ib puag ncig 3D luam tawm ntawm lub tsev kho mob thiab cov haujlwm uas tau tsav kev tsim khoom ntawm qhov chaw saib xyuas thiab qhia txog qhov ua tau," said Miriam Haerst, co-founder thiab co-CEO ntawm Kumovis.

nyob rau South Carolina 3D Cov Tshuab, yog ib lub tuam txhab qub thiab loj tshaj plaws 3D tshuab luam ntawv nyob hauv lub ntiaj teb, tsis ntev los no tau tshaj tawm nws cov phiaj xwm kom tau txais Kumovis txhawm rau nthuav dav los ntawm hlau implants rau PEEK implants ntawm qhov chaw kho mob.

"Raws li [3D luam ntawv] thev naus laus zis tau dhau los ua neeg siv ntau dua rau cov kws kho mob, ntau lub tsev kho mob yuav tuaj yeem siv cov kev daws teeb meem kawg rau kev phais tus kheej," hais tias Gautam Gupta, tus lwm thawj coj thiab tus thawj tswj hwm ntawm 3D Systems cov cuab yeej kho mob xyaum. "Qhov no yuav cuam tshuam cov qauv kev kho mob uas twb muaj lawm, txhim kho kev saib xyuas zoo, thiab qhov tseem ceeb, cawm neeg txoj sia ntau dua."

Qhov kev nrhiav tau Kumovis haum zoo rau hauv 3D Systems 'tsim kev lag luam kho mob thiab ntxiv kev tsom mus rau kev faib tawm ntawm kev tsim cov tshuaj cog qoob loo.

Haerst hais tias "Kev hloov chaw tsim khoom mus rau cov tsev kho mob yuav yog qhov hloov pauv thaum nws los txog rau qhov muaj cov khoom cog," Haerst hais.

Rau cov tsev kho mob los ua cov chaw tsim khoom, txawm li cas los xij, yuav tsum muaj cov kws tshaj lij thiab engineering, cov txheej txheem tswj hwm, nrog rau cov khoom siv. Qhov no tuaj yeem tswj hwm ntawm qhov chaw hauv kev pom zoo los ntawm cov tuam txhab kho mob tam sim no, Haerst hais.

PEEK Yas vs. Titanium rau Implants

PEEK tau muaj kev pom zoo los ntawm FDA ua cov khoom cog rau xyoo thaum tshuab, tab sis tseem tsis tau thaum 3D luam tawm. Txawm hais tias PEEK tau siv ntau qhov kev cog qoob loo ntawm kev ua lag luam niaj hnub no los ntawm cov txha caj qaum rau pob qij txha, 3D-luam tawm PEEK tseem yuav tsum tau ua pov thawj tias nws muaj qhov hnyav tib yam thiab hnav cov cwj pwm zoo li milled lossis molded PEEK.

Zuag qhia tag nrho, cov khoom siv bio-tshaj no muaj ntau qhov kev pom zoo ntawm cov hlau tsis muaj steel thiab titanium: nws yog lub teeb yuag, permeable rau ultrasound, thiab xyaum tsis pom CT thiab MRI scans ua kom zoo dua tom qab saib xyuas.

Tau ntau xyoo 3D-printed titanium tau txais lub koob npe nrov rau kev sib koom ua ke ntawm cov pob txha zoo dua thiab ntau txhiab tus pob txha thiab txha caj qaum yog 3D luam tawm txhua xyoo los ntawm cov tuam txhab loj, xws li Stryker. Tab sis PEEK tau hloov pauv, hais tias Marc Knebel, tus thawj coj ntawm kev kho mob ntawm Evonik, uas tsim PEEK rau 3D luam ntawv nrog rau kev txhaj tshuaj molding thiab milling.

"Hnub no, PEEK tuaj yeem tsim nrog cov khoom siv ntxiv kom tau txais cov yam ntxwv tshiab, xws li kev sib koom ua ke zoo dua," Knebel hais. "Peb tab tom ua haujlwm nrog ob peb lub tsev kho mob ntawm [3D-printed implants] twb lawm. Thawj cov yuav ua haujlwm nyob rau hauv tsib xyoos tom ntej. "

Lub 3D luam ntawv lab nyob ib sab ntawm chav ua hauj lwm npaj txhij rau churn tawm ib tus kheej implants tsim los ntawm tus neeg mob cov ntaub ntawv nyob rau hauv ib lub sij hawm daim ntawv ceeb toom tseem yog ib tug ntev txoj kev. Kev tswj hwm cov teeb meem tseem nyob, cov kev tshawb fawb soj ntsuam tseem tab tom ua tiav, thiab tsim kev yuav khoom los ntawm tsev kho mob yuav siv sijhawm. Qhov peb tab tom pom hnub no, txawm li cas los xij, yog cov neeg tsim kho tshiab ua thawj kauj ruam.
