Pov tseg Koob Kho Mob Qib Cov Khoom Sib Tw Technology

Kev lag luam Pain Points

Cov khoom siv tsis zoo sib xws yog ib qho kev tsis zoo hauv cov khoom siv pov tseg. Ntau lub tuam txhab pov tseg tau txais ib qho kev teeb tsa rau txhua hom khoom, tsis quav ntsej qhov xwm txheej -raws li kev ua tau zoo ntawm cov hlau tsis muaj steel thiab Nitinol hypotubes. Cov pa 304 stainless hlau yog siv ntau dhau rau ntev - lub sij hawm tiv tauj cov tshuaj tiv thaiv pov tseg, ua rau tsis muaj corrosion tsis txaus thiab cov nqaij mos mos. Tsawg- cov ntaub ntawv kawg yog sib xyaw ua ke hauv ultra- cov koob tshuaj endoscopic pov tseg zoo, ua rau tsis yooj yim thiab yooj yim kinking thaum ua haujlwm. Tsis tas li ntawd, qee lub tuam txhab siv cov tubing uas tsis tsim nyog rov ua dua los txo cov nqi, nrog rau cov khoom siv tsis zoo thiab cov khoom siv tsis ruaj khov, tsis ua raws li ib qho - siv cov qauv kev nyab xeeb kev kho mob. Cov ntaub ntawv tsis sib haum ua rau cov koob siv pov tseg kom tsis muaj qhov sib npaug ntawm lub zog thiab lub zog, tsis zoo kink tsis kam, thiab ua rau lub neej ua haujlwm luv luv, ua rau kev ua haujlwm tsis ua haujlwm thiab kev nyab xeeb kev noj qab haus huv. Qhov tsis muaj cov txheej txheem kev faib khoom thiab kev sib txuam ua ke txwv qhov kev txhim kho zoo ntawm cov khoom siv rab koob pov tseg hauv tsev.

Material Matching Txoj Cai Ua Haujlwm

Lub hauv paus ntsiab lus tseem ceeb ntawm kev xaiv cov khoom siv koob pov tseg yog qhov xwm txheej- taw qhia meej qhov sib txuam ntawm cov khoom siv kho tshuab thiab cov yam ntxwv siv cov khoom siv pov tseg. 304 stainless hlau (1.4301) nta cov khoom siv ruaj khov, tsis tshua muaj nqi, thiab qhov hnyav hnyav, haum rau cov pa luv luv - tiv tauj cov khoom siv pov tseg (14) thiab cov tshuaj tsis muaj zog (14.) 316L qis-carbon stainless hlau muaj kev tiv thaiv corrosion zoo heev thiab biocompatibility siab, zoo tagnrho rau kev siv cov tshuaj tua kab mob thiab tso zis nrog ntev -lub sij hawm tib neeg kab noj hniav sib cuag. 17-7PH siab-lub zog stainless hlau muab siab rigidity thiab siab tsis kam, siv rau pov tseg} kev txhawb nqa siab{11}. Nitinol cov duab nco alloy muaj super elasticity thiab hloov tau yooj yim pib dua kev ua tau zoo, zoo kawg nkaus txuam cov paj hlwb thiab cov hlab ntsha tawg tsawg tsawg. Cov khoom sib txuam ua kom sib npaug sib npaug, kev sib kis ntawm lub zog, kink tsis kam, thiab biocompatibility, kom ntseeg tau tias ib leeg - siv rab koob ua kom tau txais txiaj ntsig zoo hauv kev kho mob yam tsis muaj kev ua haujlwm tsis zoo.

Kev faib tawm ntawm cov khoom siv ua khoom siv

Cov khoom siv pov tseg cov khoom siv ua cov khoom siv tau raug cais raws li cov yam ntxwv ntawm cov khoom siv thiab batch ntau lawm xav tau. Pa 304 stainless hlau pov tseg koob ntau lawm txais tus qauv siab - ceev laser txiav tshuab thiab cov khoom siv polishing tsis siv neeg, nrog cov molding efficiency thiab tsis tshua muaj nqi, tsim rau loj -batch pa pov tseg cov khoom. 316L kho mob stainless hlau yuav tsum tau fine precision txiav thiab daim iav polishing khoom kom khaws nws zoo heev corrosion kuj thiab du nto kev ua tau zoo . 17-7 PH txiav thiab tawv alloy sib tsoo cov cuab yeej los daws qhov siab -hardness processing nyuaj thiab xyuas kom meej qhov tseeb. Nitinol cov koob siv pov tseg tau nruab nrog qhov tshwj xeeb tas li- cov cuab yeej ua haujlwm kub kom tsis txhob muaj lub cim xeeb kev ua tau zoo txo ​​qis los ntawm siab - kub laser txiav. Txhawb cov khoom siv kuaj cov khoom suav nrog biocompatibility analyzers, corrosion resistance testers, thiab mechanical fatigue detectors los xyuas cov khoom tsim nyog ua ntej ntau lawm.

Cov txheej txheem kev ua haujlwm ntawm cov khoom sib txuam

Ua ntej, qhia meej txog cov khoom siv pov tseg cov xwm txheej thiab cov kev pabcuam kev pabcuam: paub qhov luv luv -lub sijhawm puncture, ntev-lub sijhawm sib cuag kab noj hniav, thiab siab- qhov tseeb qhov tsawg kawg nkaus invasive scenarios los txhais cov ntsiab lus tseem ceeb ntawm kev ua haujlwm. Thib ob, siv cov khoom siv tshuaj ntsuam xyuas: xaiv 304 stainless hlau rau cov koob txhaj tshuaj uas siv tau yooj yim, 316L rau cov koob txhaj tshuaj vascular thiab tso zis, 17-7PH rau siab - rab koob txhaj tshuaj, thiab Nitinol rau kev hloov pauv micro- cov koob txhaj tshuaj. Thib peb, kho batch ua tsis tau raws li cov khoom siv: txo lub zog laser rau Nitinol ua, optimize txiav ceev rau 316L stainless hlau los xyuas kom meej smoothness. Plaub, ua cov khoom ua tau zoo ua ntej- kuaj ua ntej ntau lawm kom paub tseeb tias biocompatibility thiab mechanical stability. Thib tsib, ua raws li kev kho mob saum npoo av: kev kho mob passivation rau stainless hlau koob thiab kev kho mob los tiv thaiv kev qaug zog rau cov koob alloy. Thib rau, tsim cov khoom siv batch filing system los xyuas kom meej traceability ntawm tag nrho cov khoom siv raw cov ntaub ntawv pov tseg.

Kev paub txog kev lag luam

Hauv kev siv cov koob pov tseg ntau lawm, cov khoom sib txuam raug ncaj qha txiav txim siab cov khoom lag luam tsim nyog tus nqi. Cov ntaub ntawv tsim tawm qhia tau hais tias 316L stainless hlau pov tseg kev cuam tshuam cov koob muaj 35% kev tiv thaiv corrosion ntau dua li 304 cov khoom, zoo txo ​​qis cov ntaub so ntswg mob. Nitinol pov tseg micro- koob tuaj yeem hloov mus rau 360℃dabtsi yog khoov ntawm cov kab noj hniav nyuaj yam tsis muaj kinking, txhim kho kev ua tiav ntawm kev ua haujlwm tsawg kawg nkaus. Ntau lub tuam txhab lag luam yuam kev siv cov khoom siv siab - lub zog alloy rau cov khoom siv pov tseg, ua rau cov nqi pov tseg, thaum siv cov hlau tsis zoo tib yam rau siab - cov xwm txheej ua tau zoo ua rau kev ua haujlwm tsis txaus. Kev faib cov khoom siv sib xyaw ua ke tuaj yeem sib npaug ntawm cov khoom zoo thiab cov nqi tsim khoom, txhim kho kev lag luam kev sib tw. Tsis tas li ntawd, batch material aging testing yuav tsum tau ua ua ntej kev tsim khoom kom tshem tawm cov khoom siv raw kom txo qis los ntawm kev khaws cia ntev ntev.

Summary thiab Sublimation

Kev sib piv cov ntaub ntawv tshawb fawb yog lub hauv paus tseem ceeb ntawm kev ua haujlwm siab -kev tsim cov koob txhaj tshuaj zoo thiab tus yuam sij rau kev ntsuas kev nyab xeeb ntawm cov khoom thiab kev tswj hwm tus nqi. Cov koob tshuaj uas siv tau pov tseg muaj qhov sib txawv ntawm qhov xav tau, thiab kev teeb tsa cov khoom siv tsis tuaj yeem ua tau raws li kev kho mob sib txawv ib zaug - siv cov cai. Kev xaiv cov khoom siv meej daws cov ntsiab lus mob ntawm kev lag luam ntawm kev ua haujlwm tsis sib haum, cov nqi nkim, thiab zais kev nyab xeeb ntawm cov khoom siv pov tseg. Tsim nyog sib piv ntawm cov hlau tsis muaj hlau thiab Nitinol cov ntaub ntawv ua kom ntseeg tau tias txhua rab koob siv tau ua tiav cov kev kho mob zoo, paub txog kev sib koom ua ke ntawm kev nyab xeeb kev kho mob thiab kev lag luam ntau lawm.

Cov lus qhia txog kev txhim kho yav tom ntej

Cov kws tsim khoom siv pov tseg yuav tsum tsim kom muaj cov ntaub ntawv tiav qhov sib piv cov ntaub ntawv los tsim cov txheej txheem xaiv cov khoom tshwj xeeb rau cov khoom siv sib txawv. Nws yog ib qho tsim nyog los ua kom zoo dua - tus nqi qis thiab siab - cov txheej txheem kev ua haujlwm ntawm cov khoom siv sib koom ua ke, txo cov nqi tsim khoom ntawm qhov chaw ua kom muaj kev nyab xeeb kev kho mob, thiab txhim kho tus nqi- kev ua tau zoo ntawm cov khoom siv pov tseg. Txhim khu kev tshawb fawb txog cov khoom siv kho mob pov tseg tshiab, txhim kho biodegradable thiab siab - hloov pauv cov ntaub ntawv tshiab kom hloov mus rau yav tom ntej kev kho mob ntsuab. Nyob rau tib lub sijhawm, nruj me ntsis siv cov khoom siv raw khoom tuaj xyuas, tshem tawm cov khoom tsis tsim nyog, thiab ua kom ruaj khov rau lub sijhawm ntev -cov khoom siv koob pov tseg zoo.
