Precision Engineering: Parylene Coated Hypotubes Rau Neurological Interventions

Taw qhia: Micro-Scale Pain Point

Neurological kev cuam tshuam xav tau qhov tseeb heev vim qhov muag heev thiab nqaim vasculature ntawm lub hlwb. Ib txwm hypotubes, txawm tias thaum laser txiav, tuaj yeem tawv dhau los yog abrasive, ua rau muaj kev pheej hmoo siab ntawm cov hlab ntsha perforation. Qhov mob taw tes yog qhov xav tau rau ib lub cuab yeej uas yog ob qho tib si ultra- yoog raws thiab taug qab tau zoo ntawm micro- nplai, feem ntau qis dua 0.50mm inch. Qhov no yog qhov uas cov txheej txheem tsim khoom feem ntau poob luv.

Lub hauv paus ntsiab lus: Micro-Conformal Txheej

Parylene txheej hais txog qhov no los ntawm kev muab micro- txheej txheej uas tsis ntxiv cov khoom loj. Cov txheej txheem CVD tso cai rau cov polymer nkag mus thiab txheej txheej me me ntawm cov laser txiav, xws li cov pom ntawm cov hlab ntsha ua los ntawm 304 lossis Nitinol. Cov txheej yuav txo qhov kev sib txhuam ntawm qhov chaw kom ze rau - theem tsis txaus, ua rau lub hypotube mus rau lub paj hlwb nrog lub zog tsawg. Lub hauv paus ntsiab lus ntawm "frictionless navigation" yog ib qho tseem ceeb rau kev nkag mus rau aneurysms lossis ua thrombectomies yam tsis muaj kev puas tsuaj rau cov ntaub so ntswg.

Kev faib khoom siv rau Micro-Kev ua haujlwm

Rau kev siv neurological, cov khoom siv yuav tsum yog qhov siab tshaj plaws. Laser cutters nrog picosecond pulses yog siv los tsim cov qauv intricate ntawm cov hlab me me li 0.20mm. Lub Parylene deposition systems yuav tsum muaj ultra- tswj cov khoom zoo thiab muaj peev xwm los coated batches yam tsis tangling cov ilv hlab. Tshwj xeeb winding thiab tuav cov cuab yeej tseem tsim nyog los tiv thaiv kinking thaum txheej txheej txheej. Txhua yam khoom siv yuav tsum ua haujlwm hauv ISO 13485 cov chaw muaj ntawv pov thawj kom ntseeg tau tias muaj kev sib xws.

Phau Ntawv Qhia Txog Kev Siv: Siv Cov Khoom Siv Kom Zoo

Ua haujlwm nrog micro-hypotubes yuav tsum tau kov maj mam. Cov kev txiav laser yuav tsum tau ua kom zoo kom tsis txhob muaj cua sov- thaj chaw cuam tshuam uas tuaj yeem ua rau cov phab ntsa nyias nyias. Tom qab txiav, cov hlab yog mounted rau kev cai fixtures rau txheej kom lawv cov duab. Lub Parylene tuab yog khaws cia kom tsawg (1-2 microns) kom khaws lub raj qhov hloov tau yooj yim. Tom qab- txheej, txhua lub raj raug tshuaj xyuas nyob rau hauv lub tshuab tsom iav kom pom tseeb tias cov txheej txheej tsis sib xws thiab qhov tsis muaj qhov tsis xws luag hauv cov qauv txiav.

Tiag -Kev Paub Txog Ntiaj Teb: Kev Tshawb Fawb Kev Ua Haujlwm

Peb pab neeg tau coated hypotubes rau neurovascular catheters thiab pom tias txoj kev kawm nkhaus yog ntxhab. Thaum xub thawj, cov txheej yuav qee zaum txuas hla kev txiav uas nyob ib sab, hloov pauv qhov yooj yim profile. Peb daws qhov no los ntawm kev kho tus nqi tso nyiaj thiab siv cov khoom siv tshwj xeeb uas ua kom cov kev txiav tawm qhib. Cov lus tawm tswv yim los ntawm cov kws kho mob neurosurgeons qhia tias cov hlab ntsha coated muab kev txhim kho pom zoo hauv "pushability" thiab txo qhov xav tau kev txhawb nqa sheaths, yog li ua kom yooj yim cov txheej txheem.

Xaus thiab Sublimation

Daim ntawv thov Parylene ntawm micro-hypotubes yog qhov kev vam meej ntawm precision engineering. Nws tso cai rau cov cuab yeej siv tau nyab xeeb hla txoj hauv kev nyuaj tshaj plaws ntawm lub cev, muab kev cia siab rau cov neeg mob uas muaj cov kab mob tsis zoo. Qhov kev siv tshuab no embodies lub ntsiab ntawm qhov kev phais me me: ua ntau dua nrog tsawg dua, thiab ua kom zoo dua.

Cov kev cia siab thiab cov lus pom zoo

Lub neej yav tom ntej ntawm neuro- kev cuam tshuam yuav vam khom rau cov khoom siv coated. Peb pom zoo kom tsim Parylene formulations nrog txhim kho radiopacity los txhim kho pom kev nyob rau hauv fluoroscopy. Tsis tas li ntawd, cov kev cob qhia rau engineers ntawm micro- txheej txheem txheej yuav tsum tau tsim. Raws li qhov kev thov loj hlob tuaj, kev tsim cov khoom tsim tawm thaum tswj hwm micron- theem precision yuav yog qhov kev sib tw tseem ceeb kom kov yeej.
