Kev xa khoom hypotubes yog qhov tseem ceeb ntawm cov khoom siv kho mob hauv kev cuam tshuam kev kho mob, feem ntau yog siv hauv catheters, balloon catheters, stent delivery systems, thiab lwm yam kev cuam tshuam me me. Lawv lub luag haujlwm tseem ceeb yog muab cov channel ruaj khov rau kev xa xov hluav taws xob thaum lub sijhawm xa khoom, ua kom muaj kev thawb, tso, thiab tswj. Vim hais tias kev cuam tshuam cov cuab yeej yuav tsum ua kom muaj kev ua haujlwm zoo nyob rau hauv qhov nyuaj vascular ib puag ncig ntawm tib neeg lub cev, kev xa khoom hypotubes yog qhov zoo ntawm qhov ntev, kev ruaj khov, thiab kev tsim khoom siab, ua rau lawv tseem ceeb heev rau kev ua haujlwm tag nrho ntawm kev xa khoom.
Kev xa khoom hypotubes feem ntau yog tsim los ntawm siab- cov hlau ua tau zoo xws li stainless hlau lossis npib tsib xee-titanium (Nitinol) alloys, siv cov txheej txheem xws li precision raj kos duab, txiav laser, kho cua sov, thiab ua kom tiav. Raws li kev tsim qauv, lawv nyias nyias-walled, hollow hlau raj uas tuaj yeem tsim nrog ncaj, slotted, los yog hloov pauv tau - hloov kho kom haum raws li kev kho mob tshwj xeeb. Los ntawm kev ua cov qauv txiav tshwj xeeb rau hauv lub raj phab ntsa, qhov yooj yim thiab khoov cov yam ntxwv ntawm cov ntu sib txawv tuaj yeem raug kho kom haum- tuav lub zog siab ntawm qhov kawg ntawm qhov kawg thaum ua kom ntseeg tau zoo dua kev taug qab thiab yooj yim ntawm qhov kawg ntawm qhov kawg mus rau txoj hauv kev nyuaj vascular.
Cov txiaj ntsig tseem ceeb ntawm kev xa khoom hypotubes yog nyob rau hauv lawv qhov zoo tshaj plaws pushability, torque kis tau tus mob, thiab kink tsis kam. Thaum lub sij hawm cuam tshuam cov txheej txheem, lub zog thawb thiab kev tswj kev sib hloov tau siv los ntawm tus kws kho mob ntawm qhov kawg ntawm qhov kawg tau xa mus rau qhov kawg ntawm qhov kawg, tso cai rau lub cuab yeej txav mus rau qhov kev xav tau nrog kev txhim kho qhov tseeb thiab kev ua haujlwm ruaj khov. Tsis tas li ntawd, cov hypotubes no muaj lub zog txhua yam thiab lub neej qaug zog, ua rau lawv tuaj yeem tiv taus cov neeg kho tshuab kev ntxhov siab cuam tshuam nrog kev rov khoov dua thiab ntev - kev xa khoom. Nrog rau kev hloov pauv ntawm kev siv thev naus laus zis cuam tshuam me me, kev xa cov hypotubes tau nce zuj zus mus rau kev ua haujlwm me me, txhim kho kev yooj yim, siab -kev tsim khoom, thiab kev sib koom ua ke, yog li muab kev txhawb nqa tseem ceeb rau cov cuab yeej kho mob siab heev.
