Cov khoom xaiv rau kev cai Laser txiav Hypotube daim ntaub ntawv

Pain Points

Xaiv cov khoom siv zoo tshaj plaws rau kev cai laser txiav hypotube yog ib qho kev ntxhov siab heev. Cov kws tsim khoom yuav tsum sib haum xeeb biocompatibility, radiopacity, qaug zog tiv thaiv, thiab laser processability. Stainless hlau qib xws li 304 thiab 316L muaj ntau, tab sis lawv txhua tus teb txawv rau laser zog. Nitinol muaj qhov ua tau zoo tshaj plaws thiab kink tsis kam tab sis yog qhov nyuaj rau kev txiav yam tsis tsim cov txheej txheej tuab. Cobalt-chromium alloys xws li L605 muab lub zog siab tab sis xav tau lub zog laser ntau dua, ua rau muaj kev pheej hmoo ntawm micro- tawg. Ntau qhov dej num raug kaw vim tias cov khoom xaiv tsis tuaj yeem ua tiav qhov xav tau geometric complexity lossis ua tsis tiav cov khoom siv hluav taws xob, yuam kev rov tsim dua tshiab hauv lub voj voog txoj kev loj hlob.

Cov ntsiab cai

Laser- cov khoom sib cuam tshuam yog tswj hwm los ntawm kev nqus coefficient, thermal conductivity, thiab melting kub. Thaum lub laser beam ntaus lub raj nto, photons yog absorbed thiab hloov mus rau hauv tshav kub. Yog hais tias lub zog ceev tshaj qhov ablation pib, cov khoom yuav ejected. Qhov ua tau zoo ntawm cov txheej txheem no nyob ntawm cov khoom siv qhov cuam tshuam thiab thermal diffusivity. Piv txwv li, stainless hlau absorbs fiber ntau laser wavelengths tau zoo, thaum Nitinol qhov qis thermal conductivity tuaj yeem ua rau muaj cua sov hauv zos. Kev nkag siab txog cov ntsiab cai no tso cai rau cov kws tshaj lij tuaj yeem kwv yees qhov kev txiav zoo thiab kho qhov tsis zoo xws li lub sijhawm mem tes thiab lub zog kom txo tau cov cua sov- thaj tsam cuam tshuam thiab khaws cia txhua yam kev ncaj ncees.

Kev faib khoom siv

Cov ntaub ntawv sib txawv xav tau ntau qhov chaw laser. Fiber lasers yog lub workhorse rau stainless hlau thiab titanium, muab ib tug zoo sib npaug ntawm ceev thiab zoo. Rau Nitinol, pulsed fiber ntau lasers nrog qis zaus thiab siab dua lub zog siab dua yog nyiam los txo cov cua sov. Ultrafast lasers-picosecond thiab femtosecond- tau siv ntau dua rau kev txiav cov yam ntxwv zoo hauv cov duab-nco alloys vim tias lawv tso lub zog sai dua li cov khoom siv lub sij hawm thermal so, ua rau muaj cua sov tsawg. CO2 lasers feem ntau tsis haum rau cov hlau hypotubes tab sis yuav siv tau rau cov raj sib xyaw nrog cov txheej txheem polymer.

Phau Ntawv Qhia

Pib los ntawm kev txheeb xyuas qhov chaw kho mob: mob plawv, paj hlwb, lossis peripheral. Tom qab ntawd sau npe cov neeg sib tw cov ntaub ntawv raws li qhov yuav tsum tau ua kom yooj yim, torque, thiab radiopacity. Tau cov raj coj mus kuaj thiab ua cov kev ntsuam xyuas laser. Cov ntaub ntawv pom zoo rau txhua yam khoom siv, suav nrog focal offset, mem tes dav, thiab pab hom roj. Rau Nitinol, xav txog kev siv argon ua cov pa roj kom txo qis oxidation. Tom qab txiav, ib txwm ua electropolishing kom tshem tawm cov txheej txheem rov qab. Validate qhov kawg nrog tensile, torque, thiab qaug zog kuaj. Khaws cov ntaub ntawv txheej txheem cov ntaub ntawv txhawm rau txhim kho cov haujlwm yav tom ntej.

Tiag -Kev Paub Txog Ntiaj Teb

Ib tug neurovascular pib xaiv 304 stainless hlau rau kev qhia catheter ncej, cia siab tias yooj yim laser txiav. Txawm li cas los xij, lub vojvoog khoov nruj yuav tsum muaj cov khoom siv tau yooj yim dua. Hloov mus rau Nitinol daws qhov teeb meem hloov tau yooj yim tab sis qhia txog teeb meem txheej txheej txheej. Pab neeg no nws thiaj li tau txais ib lub laser pulsed fiber ntau nrog optimized tsis thiab ntxiv ib theem nrab electropolishing kauj ruam, ua tau zoo heev. Lwm lub tuam txhab tau kawm txog txoj kev nyuaj uas siv cov pa roj nitrogen tsis zoo ua rau pitting ntawm 316L hlab, ua rau ua rau qaug zog ntxov ntxov. Cov xwm txheej no qhia txog kev sib txuas tseem ceeb ntawm kev xaiv cov khoom siv thiab kev tswj cov txheej txheem.

Summary & Elevation

Kev xaiv cov khoom siv tsis yog tsuas yog lub thawv ntawv tshwj xeeb xwb; nws yog lub hauv paus ntawm kev ua haujlwm ntawm cov cuab yeej. Kev sib koom ua ke ntawm cov khoom siv science thiab laser technology ua rau kev tsim cov hypotubes uas tsis xav txog ib xyoo caum dhau los. Los ntawm kev nkag siab yuav ua li cas sib txawv alloys cuam tshuam nrog laser zog, engineers tuaj yeem thawb cov ciam teb ntawm kev tsim cov khoom siv tsawg tsawg. Qhov kev paub no hloov lub hypotube los ntawm cov khoom lag luam rau hauv cov cuab yeej cuab tam uas sib txawv ntawm cov cuab yeej kho mob hauv kev sib tw ua lag luam.

Kev Cia Siab & Cov Lus Qhia

Cov ntaub ntawv tshiab xws li bioresorbable hlau thiab cov khoom sib xyaw ua ke yuav xav tau cov tswv yim tshiab txiav laser. Kuv xav kom nqis peev hauv kev tshawb fawb ntawm cov lasers ntsuab, uas muaj kev nqus zoo dua hauv tooj liab thiab lwm yam khoom siv cuam tshuam. OEMs tseem yuav tsum xav txog kev txhim kho hauv -lub tsev cov txheej txheem laser kev txawj ntse es tsis yog tso siab rau cov neeg muag khoom nkaus xwb. Kev koom tes thaum ntxov nrog cov ntaub ntawv kws tshawb fawb tuaj yeem tiv thaiv kev lig - theem ua tsis tiav. Thaum kawg, tsim kom muaj kev sib koom ua lag luam database ntawm laser-cov ntaub ntawv sib cuam tshuam tuaj yeem ua kom muaj kev hloov pauv tshiab thoob plaws hauv kev lag luam.
