Pain Points

Hauv kev cuam tshuam tsawg kawg nkaus ntawm cov hlab plawv thiab cov hlab ntsha peripheral, ib qho ntawm cov kev sib tw ua haujlwm tsis tu ncua yog qhov kev nruj ntawm cov qauv catheter shafts. Pa polymer tubing feem ntau ua tsis tau qhov tsim nyog torque teb thiab pushability yuav tsum tau mus rau tortuous vascular anatomy. Cov kws kho mob feem ntau ntsib kev tawm tsam thaum nce cov khoom siv los ntawm cov hlab ntsha uas muaj calcified los yog nkhaus heev, ua rau cov txheej txheem ntau ntxiv thiab cov neeg mob yuav raug mob. Tsis tas li ntawd, tawm ntawm-- txee hypotubes tsis muaj qhov hloov kho yooj yim gradients xav tau rau cov ntawv thov kho mob tshwj xeeb. Qhov kev tsis sib haum xeeb ntawm cov cuab yeej muaj peev xwm thiab qhov kev thov anatomical tsim qhov sib txawv tseem ceeb hauv kev cuam tshuam kev ua haujlwm. Kev cai hypotube raug teeb tsa cov kev txwv no los ntawm kev ua kom muaj kev tswj xyuas meej meej, kev sib kis ntawm lub zog, thiab kink tsis kam los ntawm cov qauv laser txiav qib siab.

Txoj Cai

Lub hauv paus ntsiab lus tom qab kev cai hypotube kev ua tau zoo yog nyob rau hauv cov tswv yim tshem tawm cov khoom ntawm laser txiav los tsim engineered yooj. Lub hypotube feem ntau yog tsim los ntawm 300-series stainless hlau (304, 316L) los yog Nitinol (Ni-Ti), xaiv rau lawv cov biocompatibility, mechanical zog, thiab corrosion kuj. Laser txiav qhia cov qauv-xws li cov hlua txuas txuas ntxiv, cuam tshuam cov kauv, hlais radial, lossis cov geometries bespoke-raws li lub raj ntev. Cov qauv no hloov cov kev coj tus cwj pwm ntawm cov ncej, tso cai rau cov neeg tsim qauv tsim cov cheeb tsam ntawm qhov sib txawv nruj. Piv txwv li, ib tug nruj pitched kauv ze rau qhov kawg distal txhim kho yooj yooj yim rau navigation, thaum ib tug nruj dua proximal seem xyuas kom meej torque kis tau tus mob. Qhov tsawg kawg nkaus kerf dav ua tiav tau (zoo li 0.012 hli) ua kom muaj kev cuam tshuam cov khoom siv tsawg tsawg thaum ua kom muaj kev ncaj ncees. Qhov no precision ua rau lub hypotube ua raws li ib tug torqueable, pushable, thiab kink-resistant conduit, tseem ceeb rau niaj hnub xa khoom.

Kev faib khoom siv

Kev tsim cov kev cai hypotubes cia siab rau ntau pawg ntawm cov cuab yeej tshwj xeeb. Fiber laser txiav tshuab yog qhov nrov tshaj plaws, muab cov mem tes siab zaus thiab cov kab teeb tshwj xeeb zoo rau cov qauv sib txawv ntawm cov hlab li ntawm Ø 0.20 hli txog 20 hli. Ultrafast (picosecond lossis femtosecond) lasers tau ua haujlwm thaum ua Nitinol kom tsis txhob muaj cua sov- thaj chaw cuam tshuam thiab micro- tawg. CNC tube machining chaw muab kev ua haujlwm theem nrab xws li kev sib tsoo, flaring, thiab tipping. Electropolishing tshuab yog qhov tseem ceeb rau kev ua kom tiav, tshem tawm cov txheej txheem rov qab thiab txhim kho lub neej qaug zog. Precision mandrel kos duab cov cuab yeej ua kom qhov tseeb qhov tseeb ua ntej laser ua. Txhua daim ntawm cov cuab yeej yuav tsum tau ntsuas kom tswj tau qhov siab nyob hauv microns, vim tias qhov sib txawv me me tuaj yeem cuam tshuam cov cuab yeej ua haujlwm hauv vivo.

Phau Ntawv Qhia

Cov kws ua haujlwm ua haujlwm ntawm qhov kev cai hypotube project yuav tsum pib los ntawm kev txheeb xyuas cov kev xav tau ntawm kev kho mob: qhov xav tau yooj yim profile, torque kis tau tus mob, thiab kink tsis kam. Tom ntej no, xaiv cov khoom tsim nyog-304 stainless hlau rau kev siv dav dav, 316L rau kev txhim kho corrosion, lossis Nitinol rau kev coj tus cwj pwm superelastic. Koom tes nrog cov chaw tsim khoom los txhais cov kev xav tau no rau hauv 2D / 3D kos duab, qhia cov qauv txiav, suab, thiab thaj chaw hloov pauv. Thaum lub sij hawm prototyping, thov cov qauv nrog cov qauv sib txawv kom ntsuas qhov ua tau zoo. Validate tus tsim los ntawm lub rooj ntev zaum saum torque thiab thawb kev sim, ua raws li simulated siv nyob rau hauv anatomical phantoms. Thaum kawg, xyuas kom cov txheej txheem tsim khoom raug lees paub raws li ISO 13485 kom lav rov ua dua thiab rov ua dua.

Tiag -Kev Paub Txog Ntiaj Teb

Hauv peb qhov chaw tsim khoom, peb tau pom tias qhov kev ua tau zoo tshaj plaws kev cai hypotube tej yaam num muaj kev koom tes thaum ntxov. Piv txwv li, ib tus neeg siv khoom tsim cov kab ke neurovascular tau pib thov kom muaj cov qauv zoo ib yam. Los ntawm kev ua piv txwv, peb tau kho cov qauv mus rau qhov cuam tshuam ntawm cov kauv nrog cov kab hluav taws xob hauv cheeb tsam nyob ze ntawm qhov kawg ntawm qhov kawg, txhim kho kev taug qab ntawm cov hlab ntsha ntse. Lwm qhov xwm txheej cuam tshuam nrog lub tshuab hluav taws xob peripheral atherectomy qhov twg torque teb tsis txaus. Los ntawm kev hloov ntawm 304 mus rau 316L stainless hlau thiab kho cov laser tsis ua kom tiav 0.015 hli kerf, peb txhim kho torsional nruj yam tsis muaj kev hloov pauv yooj yim. Cov kev paub dhau los no qhia txog qhov muaj txiaj ntsig ntawm kev sib raug zoo thiab kev sim ua pov thawj hauv kev tsim kho hypotube.

Summary & Elevation

Kev cai hypotubes sawv cev rau kev sib koom ua ke ntawm cov khoom siv science, laser technology, thiab kev pom kev kho mob. Lawv hloov lub raj hlau yooj yim mus rau hauv ib qho kev ua tau zoo, kev ua tau zoo-tsim cov khoom uas ua rau cov kws kho mob kho lub cev tsis muaj zog yav dhau los. Lub peev xwm los txhim kho qhov yooj yim gradients raws ib tus ncej tsis yog ib qho kev txhim kho ntxiv xwb - nws yog ib qho kev hloov pauv hauv kev tsim cov cuab yeej siv. Raws li kev lag luam txav mus rau cov khoom siv me me, nyuaj dua, lub luag haujlwm ntawm kev cai hypotubes tsuas yog nthuav dav, tsav tsheb tshiab hauv kev saib xyuas neeg mob.

Kev Cia Siab & Cov Lus Qhia

Saib tom ntej, kev txais yuav cov kev cai hypotubes yuav nrawm rau hauv cov haujlwm tshiab xws li robotic-pab phais thiab cov txheej txheem endoscopic miniaturized. Cov neeg tsim khoom yuav tsum nqis peev rau hauv cov khoom siv laser siab heev thiab hauv - kev soj ntsuam xyuas kom txo qis kerf dav thiab txhim kho kev txiav kom zoo. Los ntawm txoj kev xav zoo, cov tuam txhab raug qhia kom tsim cov ntoo khaub lig- pab pawg ua haujlwm uas suav nrog cov kws kho mob, kws ua haujlwm, thiab cov kws tshaj lij laser los txhawb kev tsim kho tshiab. Kev cob qhia tsis tu ncua ntawm cov qauv hloov pauv xws li ISO 13485: 2016 yog qhov tseem ceeb. Thaum kawg, lub neej yav tom ntej yog rau cov neeg uas tuaj yeem sib txuas ua ke kev cai hypotube thev naus laus zis mus rau tom ntej - cov khoom siv kho mob.
