Pain Points

Thaum kev cuam tshuam catheters navigate heev tortuous vascular txoj kev xws li peripheral thiab cerebral hlab ntsha, siab rhiab heev dhau los ua qhov tseem ceeb. Ib txwm siv cov khoom hlau hypotube muaj qhov zoo torque kis tau tus mob tab sis kinks yooj yim hauv cov nkhaus nkhaus anatomical lumens. Interrupted-spiral hypotube khaws cia ib feem ntawm cov av tsis raug rau kev ua haujlwm torque, ntawm tus nqi ntawm kev txi qee yam kev ua raws li kev khoov. Polymer catheters khoov tau yooj yim tsis tau muaj teeb meem loj torque-tsawg, tsis tuaj yeem hloov pauv kev txav txav los ntawm qhov sib thooj mus rau qhov kawg. Rau qee qhov kev kho mob tshwj xeeb, qhov tseem ceeb yog muab rau qhov siab tshaj plaws khoov softness, thaum nruab nrab torque attenuation tau txais. Yog tsis tas-kab laug sab-txiav cov tshuaj hypotube, cov cuab yeej siv hluav taws xob ntsib teeb meem kom ua tiav ultra-high tubing yooj nyob rau hauv cov hlau-substrate. Ntau pab pawg OEM tawm tsam kom nrhiav tau cov khoom siv hlau xa khoom-tube tsim nyog rau cov khoom siv endoscopic uas muaj kev cuam tshuam loj heev, ua kom cov khoom tsim tawm mus ntev rau cov kev cuam tshuam ntawm cov zis thiab cov hlab ntsha peripheral.

Txoj Cai Ua Haujlwm

Nruam kauv hlais hypotube siv tsis muaj kev cuam tshuam laser-engraved kauv slots raws tag nrho cov raj ntev. Kev ua tau zoo tubing qhov ntev li ntawm Ø0.20 mm-20 mm sab nraud; Qhov tsawg kawg nkaus ua tiav kerf dav yog 0.012 hli. Kev xaiv cov khoom siv hauv paus npog 304,316L stainless hlau, 17-7PH, Nitinol thiab L605 cobalt alloy. Tsis muaj cov av uas tsis muaj hlau tsis tu ncua nyob rau ntawm qhov txuas txuas mus txuas ntxiv. Nyob rau hauv bending load, spiral-slot gaps qhib me ntsis kom nqus tau deformation hloov chaw, xa superior khoov yooj. Residual helical hlau lub vev xaib tswj kev sib txuas ntawm qhov sib txuas ntawm lub raj txuas thiab qhov xaus, ua kom muaj kev sib kis ntawm ib nrab. Spiral pitch yog qhov tseem ceeb tsis zoo: lub suab loj dua txhais tau tias tsawg dua kauv hloov ib chav tsev ntev, yooj yim dua tab sis qis torsional nruj; me me suab txhim kho torque hloov mus rau thaum txo khoov softness. Los ntawm kev kho tus nqi kauv-pitch, cov neeg tsim qauv kho qhov yooj yim-torque tshuav nyiaj li cas nyob rau hauv qhov txuas ntxiv-kab laug sab structural ciam teb. Nruam-kab laug sab geometry paub txog qhov zoo ntawm kev taug qab hauv cov lumen nkhaus rau qhov kev cuam tshuam me me ntawm cov khoom xa tuaj.

Kev faib khoom siv

Peb yam tseem ceeb ntawm cov cuab yeej tsim khoom txhawb nqa txuas txuas txuas txuas txuas txuas ntxiv cov khoom siv hluav taws xob. Ua ntej, synchronized rotary-feed nruam-kauv laser txiav tshuab: tswj lub raj sib hloov thiab linear noj mov ua ke nrog laser nruam tso zis, generating non-stop kauv kerfs. Nws yog tsim rau loj-tsim ultra-hloov hypotube rau peripheral-vascular thiab urinary endoscopic khoom. Thib ob, multi-pattern-laser-machining workstations: tuaj yeem tsim cov khoom txuas ntxiv-kab laug sab, cuam tshuam-kauv, radial-cut thiab bespoke cov qauv kev cai raws li tus neeg siv khoom 2D / 3D kos duab lossis kuaj lub cev, feem ntau yog siv rau kev tsim qauv. Thib peb, cov khoom siv tom qab ua tiav thiab ntsuas: deburring-passivation units thiab multi-functional mechanical-test benches rau qhov yooj, torque, kink-resistance thiab qaug zog-lub voj voog kev soj ntsuam. Tag nrho cov kev tsim khoom ua haujlwm ua raws li ISO 13485 thiab ISO 9001: 2015 kev kho mob-zoo-kev tswj hwm-qhov yuav tsum tau ua. Kev tshuaj xyuas cov khoom nyoos tuaj yeem tshawb xyuas qhov loj me thiab qhov zoo ntawm cov hlau tsis muaj hlau thiab Nitinol tubing.

Cov Txheej Txheem Ua Haujlwm Zoo

Paub meej tias qhov tseem ceeb ntawm daim ntawv thov kev kho mob: qhia meej tias qhov kev hloov pauv siab tshaj plaws yog lub hom phiaj tseem ceeb, thiab txhais tau tias muaj peev xwm torque-attenuation ntau yam. Paub meej tias hypotube sab nraud txoj kab uas hla, phab ntsa-thickness specification, xaiv cov khoom siv hauv qab (stainless-steel, Nitinol lossis L605). Tsim cov kev ntsuas txuas ntxiv-kab laug sab: teeb tsa tus nqi kauv-pitch, txhais kerf-dav nominal tus nqi (tsawg kawg txheej txheem kerf yog 0.012 hli). Xa cov duab kos duab kos duab lossis qauv lub cev rau kev tshuaj xyuas cov txheej txheem tsim khoom. Configure laser-processing tsis: laser zog, mem tes zaus, tsom txoj hauj lwm, raj tig thiab pub ceev. Tsim cov qauv txiav txiav. Ua kev ntsuas kev ua tau zoo ntawm cov tshuab: kev sim ua kom yooj yim-bending, ntsuas torque-transmission-efficiency, ntsuas kink-resistance thiab cyclic-bending fatigue test. Yog tias qhov kev ua tau zoo tsis sib xws, kho qhov sib npaug-pitch dimension. Execute formal laser-txiav batch ntau lawm. Ua kom deburring, kerf-ntug rounding thiab nto passivation tu txheej txheem kom tshem tawm cov ntse laser-txiav notches. Ua kom tiav qhov ntsuas qhov ntsuas. Siv cov thawv ntawv txheem lossis cov neeg siv khoom tshwj xeeb kev kho mob-qib ntim. Archive ua tiav ISO-raws li batch-production traceability cov ntaub ntawv.

Kev paub txog kev lag luam

Muaj kev xyaum qhia tau hais tias tsis tu ncua-kab laug sab hypotube muab qhov yooj yim tshaj plaws ntawm txhua hom laser-txiav-hypotube, tab sis kev ua haujlwm torsional poob pom tseeb thaum kauv-pitch loj dhau. Rau cov khoom siv peripheral-vascular dhau los ntawm cov hlab ntsha uas muaj zog heev, cov qauv tsim txuas ntxiv-kab laug sab txhawb nqa kev taug qab. Nruam-kab laug sab hypotube tsis haum raws li lub ntsiab torque-input ntu; Cov neeg tsim qauv feem ntau muab tso rau ntawm cov raj distal, thaum qhov sib thooj tau txais kev cuam tshuam-kab laug sab los yog cov khoom siv-tube rau torque input. Kerf-root notch stress concentration tseem muaj nyob; deburring thiab ntug-rounding tom qab kev kho mob tsis tuaj yeem raug tshem tawm los tiv thaiv kev qaug zog-tawg. Ntau qhov haujlwm tau ua yuam kev los ntawm kev siv lub suab nrov txuas ntxiv-kauj ruam rau qhov ntev-ntev hypotube, uas ua rau muaj peev xwm tsis txaus tag nrho. Kev simulation thiab lub rooj ntev zaum yuav tsum ntsuas ob qho tib si hloov tau thiab qhov ua tau zoo torsional ntxiv ib txhij.

Cov ntsiab lus

Nruam kauv hlais hypotube paub qhov siab tshaj plaws ntawm cov hlau-tube dabtsi yog khoov yooj yim ntawm kev tsis cuam tshuam laser-machined kauv-slot geometry. Spiral-pitch parameter tswj kev sib pauv kev sib raug zoo ntawm kev yoog raws thiab muaj peev xwm kis tau tus mob. Nws haum rau ntu ntu ntawm kev xa khoom xa mus rau tortuous anatomical lumens. Tom qab-ua tiav ntug-tiav thiab kev siv tshuab-kev ua tau zoo validation yog qhov tseem ceeb ntawm kev tswj xyuas kom zoo rau kev thov txuas ntxiv-kab laug sab hypotube kev kho mob-device.

Outlook & Cov lus qhia

Yav tom ntej technical trend tsom rau ultra-me me-inch txuas ntxiv-kab laug sab hypotube (Ø0.20-0.30 mm) rau lwm tiam micro-endoscopic instruments. Cov neeg tsim qauv yuav tsum sib txuas txuas ntxiv-kab laug sab hauv thaj tsam nrog kev cuam tshuam-kab laug sab zeem tsam tsim kom muaj kev sib xyaw-cov qauv hypotube. Cov neeg tsim khoom yuav tsum ua kom zoo dua Nitinol txuas ntxiv-kab laug sab laser-ua cov tsev qiv ntawv. Kev txheeb xyuas qhov zoo yuav tsum txhim kho kev ua haujlwm ntawm kev ua haujlwm ntawm cyclic- fatigue-life testing, kom ua tau raws li qhov kev thov kho mob loj zuj zus ntawm peripheral-vascular thiab complex urinary minimally-invasive intervention.
