Pain Points

Hauv kev cuam tshuam me me ntawm cov hlab plawv, cov kws kho mob cuam tshuam feem ntau ntsib qhov kev tsis sib haum xeeb: kev thawb thiab hloov tau yooj yim. Lub catheter yuav tsum raug thawb kom ruaj khov los ntawm qhov kawg kom ncav cuag qhov txhab mob, tab sis nws tseem yuav tsum tau hloov pauv txaus los mus rau qhov kev xav ntawm vascular anatomy yam tsis tau ua rau kev sib cais lossis perforation. Ib txwm hypotubes ua los ntawm 304 los yog 316L stainless hlau muab kev sib kis tau zoo heev tab sis yog nquag mus rau kinking thaum khoov sharply. Conversely, polymer shafts muab kev yooj yim tab sis tsis muaj qhov torsional txhav xav tau rau cov khoom siv meej tso. Qhov kev sib txawv ntawm qhov kev ua tau zoo no ua rau cov txheej txheem qeeb, muaj hluav taws xob ntau ntxiv, thiab qee zaum hloov mus rau kev phais qhib. Kev lag luam khoom siv kho mob tau ntev nrhiav cov qauv hybrid uas cuam tshuam cov kev xav tau ntawm cov neeg kho tshuab tawm tsam.

Txoj Cai Ua Haujlwm

Ib lub braid reinforced hypotube integrates ib lub laser - txiav hlau hypotube nrog ib lub tsho polymer embedded nrog ib tug braided reinforcement txheej. Lub sab hauv hypotube, feem ntau yog tsim los ntawm 304, 316L, los yog Nitinol, yog laser - txiav nrog cov qauv xws li nruam kauv los yog cuam tshuam kauv rau tailor flexibility raws nws ntev. Cov txheej txheej sab nrauv muaj cov thermoplastic polymer (piv txwv li, PEBAX, nylon, lossis polyurethane) extruded hla lub hypotube thiab ntxiv nrog cov hlua khi ua los ntawm cov hlau tsis muaj steel, Nylon, lossis siab - lub zog hluavtaws fibers. Lub braid lub kaum sab xis, suab, thiab cov khoom txiav txim siab qhov sib xyaw qhov kawg ntawm cov khoom siv kho tshuab. Thaum siv lub zog torque, lub braid txhais lub zog tig mus rau qhov kawg ntawm qhov kawg thaum lub tub ntxhais hypotube resists compression. Lub laser-txiav qauv tso cai rau kev sib dhos kom khoov tau yooj yim, thiab cov hlua khi tiv thaiv kev elongation los yog kev sib tsoo, tshem tawm kinking zoo.

Kev faib khoom siv

Manufacturing braid reinforced hypotubes yuav tsum muaj ntau pawg ntawm cov cuab yeej tshwj xeeb. Laser txiav tshuab yog thawj pab pawg tseem ceeb: femtosecond lossis nanosecond fiber ntau lasers nrog beam diameters hauv qab 20 μm yog siv los tsim cov kerfs meej raws li nqaim li 0.012 hli ntawm cov hlab li ntawm 0.20 mm txog 20 mm inch. Cov qeb thib ob yog cov tshuab braiding. Cov no suav nrog rotary braiders (16 mus rau 48 tus neeg nqa khoom) rau tubular geometries thiab maypole braiders rau siab - kev siv nro. Pab pawg thib peb yog cov khoom siv reflow lossis laminating: infrared lossis kub - cua reflow ncu uas yaj lub tsho polymer nyob ib ncig ntawm lub braid thiab hypotube los ua ib qho kev sib raug zoo. Plaub, cov lus qhia- cov tshuab tsim cov duab qhov kawg. Thaum kawg, cov cuab yeej ntsuas xws li torque teb analyzers, kink resistance testers, thiab universal tensile machines yog qhov tseem ceeb rau kev txheeb xyuas qhov zoo.

Phau Ntawv Qhia

Txhawm rau tsim lub braid reinforced hypotube, pib los ntawm kev xaiv cov khoom siv hauv lub raj. Rau kev siv cov hlab plawv, 304 stainless hlau muaj qhov sib npaug zoo ntawm lub zog thiab tus nqi. Tsim lub laser-txiav qauv siv CAD software, kom ntseeg tau tias qhov yooj yim gradient sib phim raws li kev kho mob. Txiav lub raj nrog fiber ntau laser, ces ntxuav nws ultrasonically tshem cov khib nyiab. Xaiv lub braid nrog lub kaum sab xis 45℃rau kev sib npaug torque thiab yooj. Xaub lub braid hla lub hypotube thiab npog nws nrog polymer extrusion. Siv lub qhov cub reflow ntawm 180-220℃(nyob ntawm polymer) kom yaj lub tsho, ces maj mam txias kom tsis txhob muaj kev ntxhov siab. Tom qab txias, ua qhov ntsuas torque los ntawm kev kho qhov kawg ntawm qhov kawg thiab ntsuas kev sib hloov ntawm qhov kawg ntawm qhov kawg hauv qab 50 g load. Yog tias torque efficiency qis dua 85%, kho braid nro lossis polymer durometer. Thaum kawg, ua kom tsis muaj menyuam hauv lub rooj sib txoos uas siv ethylene oxide thiab ntim rau hauv ib lub thawv ntawv lossis cov tais ntim khoom.

Tiag -Kev Paub Txog Ntiaj Teb

Ib tug thawj coj OEM nyob rau hauv Shanghai ib zaug tawm tsam nrog ib tug neurovascular nkag catheter uas kinked ntawm carotid siphon. Tus tsim qauv siv lub zog PEBAX ncej. Tom qab hloov mus rau lub braid reinforced hypotube nrog ib tug 304 core thiab 32-carrier stainless hlau braid, kinking raug tshem tawm. Txawm li cas los xij, thawj tus qauv nthuav tawm 15% poob rau hauv kev sib kis ntawm lub zog vim tsis txaus polymer sib txuas. Pab neeg tau daws qhov no los ntawm kev nce qhov kub thiab txias los ntawm 10℃thiab ntxiv ib txheej nyias nyias ntawm cov nplaum polymer. Hauv lwm qhov xwm txheej, cov chaw tsim khoom siv urology pom tias Nitinol hypotube nrog qis -pitch braid muab kev taug qab zoo heev tab sis yog nruj heev. Lawv daws qhov no los ntawm kev siv ib qho txuas txuas txuas ntxiv nrog cov suab sib txawv: nruj proximally rau pushability thiab xoob distally rau yooj. Cov piv txwv no qhia txog qhov tseem ceeb ntawm kev rov ua dua tshiab thiab kev sib koom tes ua haujlwm ntawm laser engineers thiab cov kws tshaj lij polymer.

Xaus

Braid reinforced hypotubes sawv cev rau ib qho kev daws teeb meem rau kev lag luam hauv nruab nrab -tawm ntawm kev thawb thiab yooj yim hauv catheter tsim. Los ntawm kev sib txuas lub zog torsional ntawm cov hlau hypotube nrog lub kink tsis kam ntawm lub tsho polymer braided, cov cuab yeej no ua kom muaj kev nyab xeeb dua thiab muaj txiaj ntsig zoo rau kev cuam tshuam tsawg kawg nkaus. Cov txheej txheem tsim khoom xav tau precision laser txiav, ceev faj xaiv braid, thiab tswj cov txheej txheem reflow. Tiag -kev paub hauv ntiaj teb tau lees paub tias kev saib xyuas kom meej hauv txhua kauj ruam yog qhov tseem ceeb rau kev ua tiav kev kho mob.

Outlook & Cov lus qhia

Raws li cov txheej txheem endovascular nthuav mus rau hauv ntau qhov kev ua cev nqaij daim tawv xws li mob tag nrho occlusions thiab neurovascular aneurysms, qhov kev thov rau braid reinforced hypotubes yuav loj hlob. Kev tshawb fawb yav tom ntej yuav tsum tshawb nrhiav cov duab-nco polymer braids thiab bioresorbable reinforcement cov ntaub ntawv. Cov neeg tsim khoom raug qhia kom nqis peev hauv ntau-axis laser txiav tshuab thiab tiag- sijhawm soj ntsuam cov txheej txheem los txhim kho cov txiaj ntsig. Kev koom tes nrog cov kws tshawb fawb txog cov khoom siv yuav yog qhov tseem ceeb rau kev tsim cov khoom sib txuas tom ntej - tiam. Cov koom haum tswj hwm yuav tsum xav txog kev tshaj tawm cov lus qhia tshwj xeeb rau cov khoom siv sib xyaw no txhawm rau txhim kho kev nkag mus rau kev lag luam.
