Rigid Hypotube: Interrupted Spiral Cut Design Rau High-Torque Catheter Ncej

Pain Points

High-torque interventional catheters nyob ntawm hypotubes kom hloov cov lus tsa suab los ntawm tus kov mus rau qhov kawg ua haujlwm. Ntau cov pa laser-txiav hypotubes raug kev txom nyem torque: input rotation ntawm proximal kawg tsis tuaj yeem xa mus rau qhov kawg ntawm qhov kawg, tsim kev sib hloov lag. Txawm tias muaj zog raw khoom, nruam kauv txiav qauv txi txiab torsional nruj kom yooj. Cov neeg tsim qauv ntsib teeb meem: nce kev txiav cov tav tav kom txhim kho kev ua haujlwm ntawm lub zog tsis tau muaj kev pheej hmoo poob qhov kev sib tw khiav. Nyob rau hauv peripheral-vascular thiab plab aortic aneurysm kev cuam tshuam, tsis txaus torque kis tau tus mob txo cov txheej txheem precision. Ntau tus engineers tsis ua kom zoo tshaj qhov cuam tshuam ntawm kev sib tw kauv txiav; Txoj kab dav dav tsis zoo, suab lossis kerf qhov loj me ua rau muaj kev ntxhov siab ntau ntxiv lossis cov lus teb tsis sib xws. OEMs ntsib kev rov ua qauv iteration thiab nce nqi kev loj hlob.

Txoj Cai Ua Haujlwm

Kev cuam tshuam muab kauv txiav nruj hypotube khaws cia cov khoom ntu ntu ntu nruab nrab ntawm kauv laser-cut slots. Cov khoom tsis raug txiav cov ntu no ua raws li cov txuas txuas txuas txuas nrog ntev ntev. Kev ua ntau yam npog Ø0.20 mm-20 mm sab nraud nrog qhov tsawg kawg nkaus 0.012 mm kerf dav. Kauv slots coj cov kev txwv tsis pub ua raws li, thaum cov ribs khoom dais feem ntau torsion thiab thawb load. Kho rib dav, qhov pitch thiab kerf dav hloov tag nrho rigidity thiab torsion efficiency. Cov khoom siv dav dav txhim kho lub peev xwm kis tau tus mob torque tab sis txo qhov yoog raws; nqaim ribs txhim kho khoov ua raws li thaum txo qis torsional txhav. Cov khoom siv substrates suav nrog 316L, 17-7PH, L605 thiab Nitinol txiav txim siab qhov ua tau zoo ntawm cov tshuab ua haujlwm. Cov neeg tsim qauv tuaj yeem tsim qhov sib txawv rib-dav faib raws axial kev taw qhia los tsim kev nruj gradient: dav ribs ntawm proximal kawg rau siab torque hloov, nqaim tav ntawm qhov kawg rau kev yooj yim navigation. Kev tsim khoom nruj me ntsis ua raws li ISO9001: 2015 thiab ISO13485 cov kev cai zoo rau cov khoom siv kho mob.

Cov cuab yeej & qauv kev faib tawm

Real-World Industrial Experience

Cov tswv yim tsim khoom tiag tiag hauv ntiaj teb qhia tau hais tias cov khoom nqaim dhau heev ua rau ntxov ntxov torsional tsis ua haujlwm nyob rau hauv kev sib hloov siab. Qee qhov dej num tau txais kev sib txuam-dim qhov cuam tshuam cuam tshuam rau kev txiav rau qhov ntev ntev; Qhov kev sib tw torque tau txaus siab, tab sis cov ntu ntu tau dhau los ua nruj dhau los mus rau cov hlab ntsha tortuous. Cov kws kho tsheb pom tias qhov kev hloov pauv sai sai ntawm qhov dav dav ntawm cov qauv hloov chaw tsim cov ntsiab lus kev ntxhov siab. Kev hloov maj mam rib-dav variation zoo heev txhim kho cov khoom siv lub neej. Thaum hloov cov kev cuam tshuam-kab laug sab los ntawm 316L mus rau Nitinol substrates, cov neeg tsim qauv yuav tsum ua kom dav dav; Nitinol tus qauv qis dua yuav tsum muaj cov khoom sib luag loj dua kom tswj tau qhov sib npaug ntawm qhov sib npaug ntawm qhov hnyav-torque. Post-laser ntug tiav tsis tuaj yeem hla; cov npoo ntse ntse ua rau muaj kev pheej hmoo ntawm cov hlab ntsha. Kev kuaj ua ntej ua ntej yuav pab kom tsis txhob muaj cov khoom tsim tawm ntau.
