Tus microCateter yog lub tubular kev kho mob cov cuab yeej nrog cov me me hauv thiab sab hauv diam. Nws yog tsuas yog siv los xa cov tshuaj tiv thaiv kev kuaj mob, cov khoom siv, lossis cov kab noj hniav kom ncav nrog cov neeg mob ntshav thiab cov kab noj hniav hauv tib neeg lub cev kom ua tiav cov phiaj xwm kev kuaj mob lossis kev kho mob.
Cov microcatheters tuaj yeem faib ua plaub pawg raws li lawv cov chaw thov, cov qog plawv kev cuam tshuam cov microcatheters, thiab lwm yam kev cuam tshuam microcatheters. Ntawm lawv, Neurointervional microcatheters yog tsim tshwj xeeb rau cov haujlwm kev tawm tsam hauv lub hlwb thiab tus txha caj qaum. Vim yog cov qauv anatomical ntawm lub hlwb cov hlab ntsha thiab ntau yam ntshav hlab ntsha yuav tsum muaj qhov muaj tseeb kom ncav cuag qhov chaw txhab. Piv txwv li, hauv kev phais mob xws li inreumranial aneurysm embolization thiab tus microcemer yuav tsum tau hla dhau ntawm cov kauj ruam thiab cov khoom siv uas cuam tshuam rau lub hom phiaj.
Lub microcatheter muaj lub cev raj, ib lub taub hau kawg, thiab tus Tsov tus tw kawg. Lub raj raj raj yog qhov tseem ceeb ntawm cov microcatheter thiab muaj qee qhov ntev thiab sab hauv. Lub raj raj raj yuav tsum muaj cov khoom siv tau zoo thiab kev tawm tsam los kho cov ntshav ntawm tib neeg cov hlab ntshav thiab cov kab noj hniav, thaum ua kom yooj yim tawg thaum lub sijhawm thawb khoom. Qhov ntev ntawm lub cev microcatheter sib txawv hauv cov ntawv thov sib txawv, thiab cov pob ntseg thiab cov pob negathetal feem ntau luv luv. Lub taub hau kawg yog cov khoom siv tau zoo heev, feem ntau yog nyob rau hauv maj mam tapering daim duab kom txo qis kev tiv taus thaum nkag mus rau hlab ntsha lossis kab noj hniav. Qhov yooj thiab cov duab ntawm lub taub hau kawg txiav txim siab tus xaiv super xaiv ntawm cov microCateter, uas ua rau tau yooj yim nkag mus rau cov ceg me me. Tus Tsov tus tw kawg tau txuas nrog kev ua haujlwm siv, thiab tus kws kho mob siv tus lis kev thawb, tig, thiab lwm yam haujlwm ntawm cov microcatheter. Tus tsim qauv concorms rau cov ntsiab cai ntawm Ergonomics, uas yooj yim rau cov kws kho mob kom paub meej. Nyob rau tib lub sijhawm, tus Tsov tus tw kawg yog feem ntau nruab nrog ib qho interface uas tuaj yeem txuas nrog lwm cov twj paj nruag xws li cov koob txhaj tshuaj thiab cov taw qhia.
Hais txog cov ntaub ntawv, feem ntau siv cov ntaub ntawv tubing rau cov microcatheters suav nrog polyurethane, thiab lwm yam ntawm cov hlab ntshav thaum tswj hwm lub zog; Cov microcatheters ua los ntawm polyethylene muaj cov tshuaj ruaj khov thiab biocompatibility; Cov microcatheters ua los ntawm nylon muaj qhov hnyav thiab yog siv ntau dua hauv qee cov haujlwm uas xav tau kev txhawb nqa. Txhawm rau txhawm rau txhim kho kev tawm tsam kev tawm tsam thiab thawb cov microcatheter xws li braided cov hlau thiab npib xee cov hlau roj stainless hlau txuas ntxiv rau lub cev raj. Cov ntaub ntawv uas txhawb nqa tuaj yeem ua kom cov microCatheter cov qauv ruaj khov thaum lub sij hawm thawb thiab tsis muaj kev quav lossis sib ntswg. Qee cov microcatheters yog coated nrog cov ntaub ntawv tshwj xeeb, uas tuaj yeem txo cov kev sib txhuam ntawm cov microCatheter, ua rau nws yooj yim tshaj plaws hauv cov hlab ntshav; Kuj tseem muaj cov tshuaj tiv thaiv kev tawm tsam uas tuaj yeem txo cov ntshav txhaws ntawm cov ntshav ntawm cov microcatheter thiab txo qhov kev pheej hmoo ntawm thrombosis.
Raws li cov cuab yeej tseem ceeb hauv kev ua haujlwm hauv kev ua haujlwm, cov microcatheters ua lub luag haujlwm tseem ceeb hauv kev kuaj mob thiab kho cov kab mob. Nrog kev nce qib nruam kev siv thev naus laus zis thiab kev lag luam kev lag luam yuav siv ntau yam kev txhim kho rau kev nce qib ntawm cov tshuaj tiv thaiv tshuaj.
