Daim ntawv thov ntawm Laser Vuam nyob rau hauv Medical Device Field
Jan 02, 2024
Laser vuam tshuab tuaj yeem ua tau zoo los ntawm cov kev txwv ntawm kev siv tshuab vuam tsoos, yog li nws kuj tau siv dav hauv kev kho mob thiab kev kho mob. Txij li daim ntawv thov no muaj cov kev cai nruj rau kev huv huv hauv nws cov txheej txheem tsim, laser vuam tshuab tsuas yog ua tau raws li nws cov kev xav tau. . Piv nrog rau lwm yam kev siv vuam thev naus laus zis, laser vuam tshuab tsim yuav luag tsis muaj vuam slag thiab khib nyiab, thiab tsis tas yuav tsum tau ntxiv cov nplaum nplaum thaum lub vuam txheej txheem, yog li tag nrho cov vuam ua haujlwm tuaj yeem ua tiav hauv chav huv.
Qhov sib ntxiv ntawm laser vuam tshuab tau txhawb kev txhim kho cov cuab yeej kho mob zoo heev. Piv txwv li, lub plhaub ntim ntawm cov khoom siv kho mob implantable thiab radiopaque marking cardiac stents yog txhua yam sib cais los ntawm kev siv laser vuam.
Active Implantable Medical Device
Implantable kho mob hluav taws xob cov khoom siv, xws li pacemakers, implantable electrocardiographs thiab neurostimulators (cov leeg txha caj qaum stimulators, sib sib zog nqus hlwb stimulators thiab implantable cochlear implants, thiab lwm yam), yog siv nyob rau hauv tib neeg lub cev los tswj thiab kho lub cev lub physiology tej yam kev mob xws li lub plawv dhia, ntev. mob, Parkinson's disease, lossis lag ntseg hnyav. Ntau xyoo dhau los, kev siv cov khoom siv hluav taws xob kho mob implantable tau loj hlob ntawm tus lej ob tus lej rau cov neeg mob txhawm rau txhim kho lawv lub neej zoo.
Cov khoom siv hluav taws xob implantable no feem ntau muaj microelectronic circuits thiab roj teeb uas muab lub zog. Txhawm rau tiv thaiv microelectronic circuits thiab roj teeb, lawv yuav tsum tau muab kaw thiab ntim rau hauv cov hlau casings. Yog tias lub foob ploj lawm, cov kua hauv lub cev tuaj yeem nkag mus rau hauv cov ntim hlau ncaj qha, ua rau luv luv Circuit Court tsis ua haujlwm ntawm microelectronic Circuit Court thiab ua rau muaj kev phom sij rau tus neeg mob lub neej.
Laser vuam tshuab yog feem ntau siv kev sib txuas thiab sealing tshuab rau implantable cov cuab yeej kho mob. Lub plhaub hlau ntawm cov khoom siv kho mob cog tau feem ntau siv titanium thiab titanium alloys. Txawm li cas los xij, titanium muaj peev xwm nqus tau hydrogen, oxygen, thiab nitrogen ntawm qhov kub thiab txias. Yog li ntawd, cov txheej txheem laser vuam yuav tsum tau ua nyob rau hauv ib qho inert gas kaw ib puag ncig.
Hauv laser vuam, kev tswj ntawm lub zog laser plays lub luag haujlwm tseem ceeb hauv kev vuam zoo. Thaum laser irradiates ib tug hlau nto, 60% mus rau 80% ntawm lub zog laser yuav tshwm sim thaum xub thawj. Raws li qhov kub thiab txias, cov hlau nqus ntawm laser zog yuav maj mam nce. Thaum nws ncav cuag qhov kub siab, nws tuaj yeem nqus tau ze li 90% ntawm lub zog.
Cov Khoom Siv Kho Mob Passive
Active implantable cov cuab yeej kho mob muaj cov cai nruj heev rau kev sib khi ntawm cov txheej txheem laser vuam. Feem ntau siv cov txheej txheem xau kom pom zoo yog helium spectrometry. Tus qauv tub rog MIL-STD-883 (1014) qhia txog txoj hauv kev kom pom cov dej xau zoo. Daim ntawv thov ntawm laser vuam nyob rau hauv cov khoom siv kho mob passive feem ntau yog rau kev sib txuas, uas tuaj yeem ua tiav qhov vuam ntawm qhov me me.
Lub plawv stent
Lub plawv stent, tseem hu ua coronary stent, yog cov cuab yeej kho mob uas feem ntau siv hauv kev phais plawv thiab muaj kev ua haujlwm ntawm kev thaiv cov hlab ntsha thiab cov hlab ntsha. Cov ntaub ntawv tseem ceeb yog stainless hlau, nickel-titanium alloy lossis cobalt-chromium alloy.
Thaum lub sij hawm tus txheej txheem ntawm lub plawv stent raug xa mus rau tag nrho txoj kev mus rau nws lub hom phiaj, lub radiopaque ntsiab nyob rau hauv ob qho tib si kawg ntawm lub stent yuav kom meej meej pom nws cov kab thiab nthuav raws li txoj cai. Cov cim hluav taws xob tuaj yeem ua los ntawm cov hlau muaj txiaj ntsig xws li kub, tantalum, platinum thiab iridium, thiab cov cim tuaj yeem Riveting, cov txheej txheem molding no tuaj yeem siv lub laser nrog qhov tsawg kawg nkaus qhov chaw txoj kab uas hla ntawm 40μm (0.04mm) rau weld lub disc-shaped marker rau hauv ib lub qhov muag tshwj xeeb.
Gastroscopy biopsy forceps
Lub gastroscopic biopsy forceps siv nyob rau hauv kev kho mob yuav tsum tau nkag mus tob rau hauv tus neeg mob lub cev, yog li cov kev cai zoo rau lub biopsy forceps yog nruj heev. Txhua feem ntawm biopsy forceps yuav tsum tau ua kom tau raws li lub zog tensile thiab zoo tsos, tshwj xeeb tshaj yog qhov chaw tsis pub muaj Burrs, thiab lwm yam.
Hauv kev tsim khoom thiab kev ua haujlwm dhau los, qhov kawg ntawm lub gastroscope biopsy forceps tau sib xyaw ua ke los ntawm riveting, tsis kam vuam, thiab lwm yam. Txoj kev riveting yuav tawm burrs thiab lwm yam tsis xws luag rau ntawm qhov chaw ntawm rab phom, thiab kev siv vuam kuj tseem yuav ua rau muaj kev sib tsoo. qhov chaw los tsim kev puas tsuaj ntau. Loj deformation cuam tshuam rau kev siv ntawm cov phom puncture. Txawm li cas los xij, laser vuam tshuab muaj cov yam ntxwv ntawm kev ua tsis sib cuag, nqaim thermal cuam tshuam ntau yam, kev ua haujlwm siab, thiab kev ua haujlwm siab. Nws tuaj yeem paub qhov tsis muaj qhov tsis zoo, tsis muaj zawv zawg, tsis muaj crease-free, thiab seamless instruments hauv kev kho mob. Burr thiab tawg-dawb vuam xav tau.
Kev taw qhia ntawm laser vuam tshuab ua rau cov khoom siv kho mob ntau dua, yooj yim dua thiab xis dua. Ntxiv nrog rau laser vuam, lwm yam laser ua technologies kuj muaj lub peev xwm loj hauv kev tsim cov khoom siv kho mob, xws li laser tu, laser txiav, laser drilling thiab laser micromachining.
