Micro Laser Txiav Ntawm 316LVM Hypotube Rau Tsawg Tshaj Tawm Endoscopy

Pain Points hauv Miniaturization​

Cov khoom siv endoscopic xav tau micro-hypotubes (OD < 1 mm) uas hloov pauv tsis tau torqueable. Kev tsim cov khoom me me 316LVM yog cuam tshuam los ntawm cov phab ntsa nyias (0.02 hli) uas deform yooj yim, thiab xav tau 0.012 hli kerf yam tsis muaj thermal puas. Kev xa tawm yog tsawg, thiab cov nqi siab. Qhov delicacy heev ntawm cov hlab no ua rau lawv raug kev co thaum txiav, thiab txawm tias me me thermal distortion tuaj yeem ua rau lawv siv tsis tau. Tsis tas li ntawd, cov lumen nqaim tuaj yeem ua rau txhaws nrog cov khoom molten lossis pab cov pa paug, yuav tsum tau ua tib zoo tu cov txheej txheem. Qhov tsis muaj cov txheej txheem txheej txheem rau micro laser txiav ntxiv nyuaj rau kev teev-up, raws li txhua tus qauv tshiab yuav xav tau kev ua kom zoo dua qub. Tus nqi siab ntawm cov khoom siv laser ultra-ceev thiab xav tau rau cov chaw tshwj xeeb nrog kev tswj kub thiab av noo ntxiv rau lub nra nyiaj txiag. Tsis tas li ntawd, txoj kev mus rau ib leeg-siv endoscopes nce qhov kev thov rau tus nqi tsim nyog micro-hypotubes, tso siab rau cov tuam txhab kom sib npaug zoo nrog kev them taus.

Txoj cai ntawm Micro Laser Txiav​

Ultra-ceev lasers (picosecond / femtosecond) pab kom txias ablation, txiav micro-feature nrog negligible HAZ. High-precision theem thiab lub zeem muag saib xyuas kom raug. Qhov chaw laser yog tsom mus rau <20 µm, tso cai rau cov qauv sib txawv ntawm micro-tubes. Cov txheej txheem tso siab rau ntau qhov kev nqus ntawm photon thiab Coulomb tawg kom tshem tawm cov khoom tsis muaj kev hloov pauv kub. Los ntawm kev kho cov mem tes zog, rov ua dua tus nqi, thiab scan ceev, qhov kev txiav zoo tuaj yeem ua kom zoo dua rau qhov tsawg kawg nkaus. Kev siv lub tshuab nqus tsev chucks tiv thaiv kev txav ntawm lub raj, thiab cov pa coaxial pab ua kom cov khib nyiab pov tseg. Lub hauv paus physics suav nrog kev sib cuam tshuam ntawm ultra-luv pulses nrog cov hlau electron lattice, qhov twg lub zog sib txuas sai sai uas cov lattice tsis muaj sij hawm los ua kom sov, ua rau kom huv si. Lub hauv paus ntsiab lus no yog qhov tseem ceeb rau kev tswj xyuas cov khoom siv kho tshuab thiab kev tiv thaiv corrosion ntawm 316LVM hauv micro-scale Cheebtsam.

Classification ntawm Micro Laser Equipment​

Picosecond lasers (piv txwv li, 1064 nm, 10 W), femtosecond lasers, thiab high-resolution motion systems. Lub tshuab nqus tsev chucks tiv thaiv lub raj txav. Qee lub tshuab ua ke ob lub lasers: ib qho rau kev txiav ntxhib thiab lwm qhov rau kev ua tiav zoo. Beam xa tuaj yeem suav nrog spatial light modulators rau beam shaping. Environmental controls xws li kub stabilization thiab kev vibration cais yog ib qho tseem ceeb los tswj qhov tsim nyog precision thaum txiav. Lub zeem muag nrog lub ntsej muag loj thiab lub ntsej muag telecentric ua kom muaj kev sib raug zoo, thaum lub tshuab fume extraction tshem cov khoom ablated los tiv thaiv kev sib kis. Kev xaiv cov cuab yeej yog nyob ntawm qhov xav tau qhov tseeb, kev tsim khoom nrawm, thiab peev nyiaj, nrog ultra-ceev lasers yog qhov kev xaiv zoo tshaj plaws rau kev siv kho mob tseem ceeb txawm tias lawv cov nqi siab dua.

Phau Ntawv Qhia Txog Kev Ua Haujlwm​

Siv lub picosecond laser ntawm 5 µJ mem tes zog. Ruaj ntseg raj nrog lub tshuab nqus tsev. Txiav qauv nrog 0.01 hli kerf. Tom qab txheej txheem nrog micro-electropolishing. Tshawb xyuas nrog confocal microscope. Tswj ambient tej yam kev mob: kub 20 ± 1 degree, av noo 40-50%. Validate txheej txheem ntawm DOE. Siv SPC rau cov kev ntsuas tseem ceeb. Cov ntaub ntawv txhua kauj ruam rau kev ua raws ISO 13485. Ua qhov kev ntsuam xyuas txhua yam kom ntseeg tau tias micro-hypotube ua tau raws li qhov yuav tsum tau ua kom yooj yim thiab torque. Nws tseem yog ib qho tseem ceeb los tsim kom muaj ib qho chaw huv huv (Class 1000 lossis zoo dua) kom txo tau cov paug paug thaum tuav thiab ua haujlwm. Tsis tu ncua calibration ntawm lub laser thiab kev txav tshuab yog tsim nyog los tswj cov micron-theem qhov yuav tsum tau rau micro-txiav.

Kev paub tiag-lub ntiaj teb​

Peb tsim OD 0.4 hli, phab ntsa 0.03 hli 316LVM hypotubes rau endoscopic forceps. Cov hluav taws xob zoo li qub ua rau lub raj tawg; daws nrog ionized cua. Kev kho kom pom tseeb ntawm lub sijhawm tiag tiag khaws cia kerf sib xws. Hauv ib qhov project, tus neeg siv khoom xav tau ib qho kev hloov pauv tau yooj yim rau cov khoom siv colonoscopy; peb siv cov qauv txiav radial nrog ntau qhov sib txawv, ua tiav qhov xav tau yooj yim yam tsis muaj kev cuam tshuam torque. Txawm li cas los xij, peb tau ntsib teeb meem nrog kev pab roj purity; hloov mus rau ultra-high-purity argon tshem tawm micro-burrs. Cov kev paub dhau los no tau qhia peb tias micro-txiav xav tau tsis yog cov cuab yeej siv siab xwb tab sis kuj tseem muaj kev tswj hwm ib puag ncig thiab kev qhuab qhia zoo. Kev muaj peev xwm hloov tau sai sai rau cov kev cov nyom uas tsis tau pom dua, xws li cov khoom siv sib txawv lossis kev kho qhov muag tsis zoo, yog qhov tseem ceeb rau kev ua tiav.

Summary thiab Sublimation​

Miniaturization ntawm 316LVM hypotube thawb cov ciam teb ntawm qhov ua tau nyob rau hauv endoscopy. Txhua lub raj micro-txiav yog yeej rau kev phais tsawg dua, qhia txog kev lag luam kev cog lus rau kev tsim kho tshiab. Qhov kev sim siab no ua rau lub siab ntawm precision engineering, qhov twg txhua micron suav thiab txhua qhov kev txiav tuaj yeem ua qhov sib txawv hauv kev saib xyuas neeg mob. Raws li peb txuas ntxiv txo qhov loj ntawm cov cuab yeej kho mob, peb yuav tsum nthuav peb txoj kev paub thiab kev muaj peev xwm, kom ntseeg tau tias qhov zoo thiab kev ntseeg siab yeej tsis muaj kev cuam tshuam. Lub micro-hypotube yog ib qho pov thawj rau tib neeg kev txawj ntse thiab kev nrhiav tsis tu ncua ntawm kev kho mob zoo dua.

Cov kev cia siab yav tom ntej thiab cov lus pom zoo​

Adaptive optics thiab holographic beam shaping yuav txhim kho precision. Kev koom tes nrog cov kws kho mob yuav txhawb nqa cov tswv yim tshiab ntawm micro-device. Cov neeg tsim khoom lag luam yuav tsum nqis peev hauv automation kom nce kev nkag mus thiab txo cov nqi. Kev tshawb fawb rau lwm cov ntaub ntawv xws li nitinol rau cov ntawv thov tshwj xeeb tuaj yeem ntxiv 316LVM. Raws li tus kheej cov tshuaj loj hlob tuaj, lub peev xwm los tsim cov neeg mob tshwj xeeb micro-hypotubes sai sai yuav dhau los ua kev sib tw kom zoo dua. Kev lees txais cov kev tsim khoom digital thiab AI-tsav cov txheej txheem tswj hwm yuav ntxiv dag zog rau lub peev xwm ntawm micro laser txiav, paving txoj hauv kev rau tiam tom ntej ntawm cov khoom siv endoscopic uas me dua, ntse dua, thiab ua tau zoo dua.
