Kev Kho Mob Tubing - Kev qaug zog ua haujlwm nyob rau hauv Cyclic Bending & Torsion

Qhov mob tseem ceeb nrog cov raj kho mob hauv cov khoom siv rov siv tau lossis ntau- lub voj voog kev cuam tshuam yog qaug zog tsis ua haujlwm tom qab rov khoov thiab sib tw. Nyob rau hauv kev nruam cyclic mechanical load, microcracks pib ntawm laser txiav npoo ntawm cov tubing kho mob thiab maj mam propagate ntau txhiab lub voj voog, nws thiaj li ua rau lub raj tawg, lumen to los yog mus tas li deformation. Txawm hais tias lub hypotube dhau qhov kev sib tw static thiab lub rooj ntev zaum torque, nws yuav ua tsis tau tom qab ntau txhiab lub voj voog thaum lub sij hawm ua kom muaj zog. Kev qaug zog tsis ua hauj lwm ntawm kev kho mob tubing ua rau muaj kev phom sij loj rau cov cuab yeej siv hauv kev siv vascular navigation, thiab nws sawv cev rau ib qho ntawm cov kev ua tsis tau zoo tshaj plaws thaum lub sij hawm ua ntej - kev soj ntsuam ceev kom siv tau ntev. Pab pawg OEM siv ntau qhov kev tsim kho vaj tse rov tsim kho hypotubes ntau zaus thaum kev kho mob tubing qaug zog ua tsis tau raws li lub hom phiaj ntawm lub neej voj voog. Ntau pab pawg tsim underestimate stress concentration ntawm laser txiav npoo thiab kho zoo li qub mechanical zog raws li cov pov thawj txaus rau ntev -lub sij hawm durability.

Lub hauv paus ntsiab lus ntawm qaug zog ntawm cov qauv kho mob tubing cuam tshuam rau kev ntxhov siab concentration ntawm cov npoo. Ntws notches thiab micro- qhov tsis xws luag ntawm qhov npoo ua kom muaj kev ntxhov siab hauv zos nyob rau hauv lub voj voog, ua kom nrawm nrawm nrawm. Smooth, rounded laser npoo txo ​​qhov kev cuam tshuam no thiab qeeb tawg pib. Cov khoom siv microstructure thiab alloy purity ntawm kev kho mob tubing kuj txhais lub hauv paus qaug zog tiv thaiv. Peb laser txiav tshuab tsim 0.012mm zoo kerf ntawm kev kho mob tubing xws li Ø0.20mm txog 20mm. Los ntawm kev xaiv lub siab purity kho mob tubing alloys thiab optimizing qauv geometry, peb kis tau cyclic kev nyuaj siab nyob rau hauv ntau lub ribs dav es tsis txhob tsom rau kev nyuaj siab ntawm ib tug me me ntawm nqaim txiav nta. Kev cuam tshuam cov qauv ntawm cov kauv tsim kom dav dua-cov kabmob tav uas txhim kho lub neej qaug zog piv nrog kev txiav txuas txuas txuas ntxiv ntawm tib lub raj kho mob dawb paug. Nqus kev nyuaj siab nyem tom qab ua laser tshem tawm cov seem thermal thiab mechanical stressed nyob rau hauv lub raj phab ntsa thaum txiav, tiv thaiv gradual kev nyuaj siab tsub kom thaum rov khoov thiab torsion.

Cov ntaub ntawv kho mob tubing raug cais los ntawm kev muaj peev xwm qaug zog kom ua tau raws li qhov kev xav tau ntawm lub neej sib txawv. L605 kev kho mob tubing muab qhov ua tau zoo siab - lub voj voog qaug zog ua haujlwm, nyiam rau peripheral vascular hypotubes nrog rov ua dua los ntawm ntau lub nkoj khoov . 316L cov tubing kho mob muaj kev qaug zog zoo rau cov hlab plawv PTCA cov khoom siv nyob rau hauv nruab nrab cyclic load. Nitinol kev kho mob tubing siv tus cwj pwm superelastic los tiv thaiv qhov kev hloov pauv mus tas li nyob rau hauv cyclic dabtsi yog khoov rau neuro microcatheters. 17-7PH kev kho mob tubing muab lub zog tensile siab rau qis- voj voog siab -load AAA daim ntawv thov. 304 kev kho mob tubing suits qis- lub voj voog tso zis endoscopic cov khoom siv nrog tsawg dua cov kev xav tau rov ua dua. Txhua alloy muaj cov yam ntxwv sib txawv tawg, yog li cov qauv rib dav thiab ntug xov yuav tsum tau hloov kho kom tau raws li lub hom phiaj ntawm lub voj voog suav.

Kev ua haujlwm ua haujlwm rau kev qaug zog-kev kho mob zoo tshaj plaws tubing hypotubes: Txhais lub voj voog uas xav tau, khoov amplitude thiab torsion lub kaum sab xis yuav tsum tau los ntawm OEM cov ntaub ntawv tshwj xeeb. Xaiv qhov tsim nyog kho mob tubing alloy, OD, ID thiab phab ntsa tuab. Xaiv hom qauv; interrupted kauv feem ntau yog nyiam rau qaug zog- daim ntawv thov kev kho mob tseem ceeb. Calibrate laser kom huv si 0.012mm kerf thiab txo cov thermal puas rau kev kho mob cov npoo npoo. Tshaj tawm - txheej txheem deburring, electropolishing thiab nqus kev ntxhov siab kho kev kho kom hloov pauv cov npoo thiab txo qis kev ntxhov siab. Khiav nrawm cyclic dabtsi yog khoov thiab torsion qaug zog kuaj, tsis tu ncua kuaj cov qauv rau kev pib tawg tom qab ncav lub hom phiaj. Tswj ISO13485 traceability thiab ua tiav batch ntau lawm cov ntaub ntawv. Pob tiav lawm hypotubes rau cov neeg siv khoom tshwj xeeb.

Factory kev ua tau zoo validates tus nqi enormous ntawm kev nyuaj siab nyem thiab ntug polishing rau kev kho mob tubing qaug zog lub neej. Lub peripheral hypotube ua los ntawm L605 kev kho mob tubing nrog unpolished laser npoo ua tsis tau tejyam tom qab tsuas yog 22,000 dabtsi yog khoov voj voog, nrog pom microcracks originating los ntawm txiav cov ces kaum. Tom qab electropolishing thiab nqus kev ntxhov siab kev kho mob ntawm cov tubing kev kho mob zoo tib yam thiab cov qauv tsim, cov qauv muaj sia nyob ntau dua 800,000 lub voj voog yam tsis muaj kev tawg lossis tawg mus tas li. Qhov txiaj ntsig zoo no tau ua pov thawj ntug tiav thiab qhov seem ntawm kev ntxhov siab ntawm kev kho mob tubing laser txiav yog qhov tseem ceeb hauv kev txiav txim siab qaug zog lub neej, cuam tshuam ntau dua li kev xaiv raw khoom ib leeg.

Hauv cov ntsiab lus, cyclic fatigue tsis ua haujlwm ntawm laser-txiav hypotubes pib los ntawm kev ntxhov siab ntawm kev txiav cov npoo ntawm cov raj kho mob. Kev xaiv cov khoom siv, qauv tsim thiab ntug tiav ua ke txiav txim siab lub neej kev pab cuam ntawm kev kho mob tubing nyob rau hauv rov qab txhua yam load. Cov npoo du txo cov ntsiab lus pib tawg thiab ua kom ntev lub neej siv tau ntawm lub cev tiav lawm. Residual stress relief tom qab laser txiav yog qhov tseem ceeb rau siab - daim ntawv thov kev kho mob.

Kev txhim kho yav tom ntej: Kev sim ua kom nrawm nrawm uas siv cov ntsiab lus finite tsom xam yuav siv dav dua los kwv yees kev kho mob tubing ua ntej txiav cov qauv ntawm lub cev. Kev kho mob tubing nrog ultra- ntxuav laser txiav thiab optimized alloy microstructure yuav txhawb cov tiam tom ntej ntawm cov khoom siv ruaj khov rau kev cuam tshuam rau peripheral thiab neurovascular, txo qhov kev pheej hmoo ntawm kev kho mob thiab txuas ntxiv cov kev pabcuam khoom siv.
