Rigid Hypotube: Cov Cai Xaiv Cov Khoom Siv Rau Siab-Load Catheter Shafts

Pain Points

Cov kws tsim qauv tsim feem ntau kho cov khoom siv hypotube nruj raws li kev xaiv qib yooj yim. Ntau pawg xaiv stainless-steel hypotube raws li qhov kev ua haujlwm dhau los uas tsis muaj cov khoom siv kho qhov muag rau qhov chaw kho mob tiag tiag. Kev siv 304 stainless hlau rau high-torsion hnyav-load scenarios ua rau cov ncej twist thiab lub zog poob . 316L tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog siab rau cov cuab yeej cuam tshuam. Qee tus engineers ncaj qha hloov mus rau Nitinol rau lub cev tsis muaj zog tsis muaj kev txwv txiav qhov ntom, thiab cov khoom kawg poob qhov kev cia siab ntawm lub zog. Cov khoom siv tsis raug-tus qauv sib piv ua rau cov khoom siv hluav taws xob raug nqi, ncua kev loj hlob mus ntev thiab muaj peev xwm muaj kev phom sij rau tus neeg mob. Nyob rau theem kev yuav khoom, tsis muaj cov ntaub ntawv pov thawj pom tseeb yuav ua rau cov khoom siv sib xyaw ua ke tsis sib xws raws li ISO13485 kev tswj hwm zoo.

Txoj Cai Ua Haujlwm

Lub rigidity kev ua tau zoo ntawm rigid hypotube yog sib koom ua ke los ntawm cov khoom siv elastic modulus, yield zog thiab laser-cut slot layout. Kev ua haujlwm muaj peev xwm npog Ø0.20 mm-20 mm sab nraud thiab qhov tsawg kawg nkaus 0.012 mm kerf dav. High-yield-lub zog hlau substrates tuaj yeem txhawb nqa loj dua thiab torsional load ua ntej cov yas deformation tshwm sim. Laser-cut slots tshem tawm ib feem ntawm cov khoom siv phab ntsa thiab txo tag nrho rigidity; cov ribs ruaj khov kho lub zog. Rau daim ntawv thov nruj hypotube, txiav qhov ntom yuav tsum tau tswj kom khaws cov khoom txuas ntxiv kom txaus. Cov qib sib txawv ntawm cov hlau sib txawv qhia pom qhov txawv txav: 17-7PH nag lossis daus hardening stainless hlau tau txais lub zog siab tom qab kev kho cua sov; L605 cobalt alloy sib npaug lub zog thiab qaug zog ua haujlwm; 304 thiab 316L muab kev ruaj khov rau lub hom phiaj rigidity. Nitinol-raws li txhav hypotube cia siab rau kev txiav me me; nws tus yam ntxwv super-elastic tsis txhob mus tas li kink txawm nyob rau hauv loj deflection. Laser-pattern tsim modulates hauv zos rigidity ntawm qhov chaw ntawm lub hauv paus-cov ntaub ntawv kev ua tau zoo qab nthab. Txhua qhov kev tsim khoom ua raws li ISO9001: 2015 thiab ISO13485 cov qauv kev kho mob-cov cuab yeej zoo.

Cov cuab yeej & qauv kev faib tawm

Interrupted Spiral Cut Pattern: Periodic uncut solid ribs tuav lub zog ntawm sab, haum rau 316L,17-7PH thiab L605 rigid hypotube rau PTCA thiab peripheral-vascular xa. Continuous Spiral Cut Pattern with low‑density slots: delivers medium rigidity, applies to urinary endoscopic device shafts. Radial Cut Pattern: feem ntau ntawm cov ncej tseem nyob ruaj khov, tsuas yog cov kab hluav taws xob sib cais tsim cov cheeb tsam hloov tau yooj yim rau cov khoom siv paj hlwb tshwj xeeb. Bespoke Cut Patterns: kev cai ntau ntu rigidity gradient raws li tus neeg siv khoom 2D / 3D kos duab lossis qauv lub cev. Cov khoom siv rau lub cev tsis muaj zog: 1) 304 / 316L stainless hlau: tus nqi tsim nyog cov khoom siv rau cov khoom siv qis rau nruab nrab; 2) 17-7PH: high-strength nag lossis daus-hardening stainless hlau rau high-torsion hnyav-load scenarios; 3) L605 cobalt-chromium alloy: zoo heev cyclic-fatigue tsis kam; 4) Nitinol: sparse-txiav nruj hypotube rau scenarios xav tau rigidity ntxiv rau cov duab-memory.

Cov Txheej Txheem Ua Haujlwm Zoo

Txhais kev thauj ciam ciam teb ua ntej: lub zog thawb siab tshaj plaws, qhov siab tshaj plaws torsion torque, cyclic dabtsi yog khoov lub sijhawm thiab cov kev xav tau los tiv thaiv kink. Match cov khoom qib rau qib load: xaiv 17-7PH rau siab-torsion hnyav-load; txais yuav 316L rau cov khoom siv cuam tshuam cov pa; siv L605 yog tias lub sij hawm ntev cyclic qaug zog kuj tseem ceeb. Thaum Nitinol raug xaiv rau nruj hypotube, txwv tsis pub laser-txiav ntom hauv cov duab kos. Xa 2D / 3D kos duab lossis cov qauv ntawm lub cev rau cov chaw tsim khoom; cim kerf dav kam rau ua, qauv hloov chaw, kev kho cua sov rau 17-7PH. Xav tau cov ntaub ntawv raw cov ntaub ntawv pov thawj. Ua kom tiav thawj-kab tshuaj ntsuam xyuas: ntsuas qhov ntev, ntsuas qhov dav dav (tsawg kawg ua tiav 0.012 hli). Execute push-compression test, torsion cycle test and fatigue testing. Tshawb xyuas qhov burr thiab ntug zoo. Txais cov thawv ntim khoom lossis kev ntim khoom tiv thaiv rau kev xa khoom.

Real-World Industrial Experience

Ntau qhov teeb meem kev loj hlob qhia txog cov khoom siv-mismatch yuam kev. Ob peb pab pawg OEM siv 304 stainless-steel cuam tshuam-kauv hypotube rau siab-torque peripheral-vascular cuam tshuam; nyob rau hauv kev kho mob thawb-twist ua haujlwm, yas twist deformation tshwm sim, thiab lub hom phiaj kev nkag mus ua tsis tiav. Qee qhov dej num tau xaiv Nitinol tab sis siv cov kev sib tw siab ceev, cia siab tias qhov kev ua tau zoo ntawm lub cev; Qhov kawg ncej nthuav tawm ntau qhov yooj thiab buckled nyob rau hauv lub laub load. Cov kws kho tsheb tau kawm tias lub xeev kev kho cua sov ncaj qha txiav txim siab 17-7PH rigidity tso zis; Cov qauv laser zoo ib yam ntawm qhov sib txawv-hardness 17-7PH tubing tsim cov txiaj ntsig sib txawv kiag li. Ncaj qha hloov cov qauv stainless-steel qauv tsis mus rau Nitinol rigid hypotube ib txwm ua rau kev ua haujlwm sib txawv. Pre-production qauv validation zoo txo ​​cov khoom-xaiv kev pheej hmoo.

Summary & Insight

Cov ntaub ntawv qib tsim cov kev ua tau zoo qab nthab rau kev nruj hypotube, thaum laser-txiav qauv txiav txim siab ua haujlwm rigidity. Tsis muaj cov khoom siv zoo tshaj plaws thoob ntiaj teb; xaiv yuav tsum ua raws li kev kho mob load profiles. 17-7PH thiab L605 ua haujlwm siab-load rigid scenarios; 316L haum rau kev siv dav dav; Nitinol tuaj yeem paub lub cev tsis muaj zog tsuas yog nyob rau hauv qhov txwv-txiav-qhov ntom ntom tsim. Cov ntaub ntawv pov thawj, kos duab pom tseeb thiab kuaj lub rooj zaum yog qhov tseem ceeb ntawm kev tswj xyuas kev sib txuas rau cov khoom siv kho mob qib hypotube.

Yav tom ntej Outlook & Cov Lus Qhia

Yav tom ntej rigid hypotube cov ntaub ntawv innovation tsom mus rau optimized alloy mis thiab multi-khoom integrated ncej qauv.
