Ua ntej dhia mus rau hauv lub ncauj lus ntawm Hypotubes, cia peb nkag siab txog qhov kev xav tau ntawm kev kho mob tshwj xeeb.

Thaum lub sij hawm coronary angioplasty, cov kws kho mob feem ntau yuav tsum tau siv lub zog loj heev los coj cov catheter los ntawm cov hlab ntsha. Qee lub sij hawm, thaum qhov mob hnyav heev, lub catheter nyuaj rau nkag mus rau hauv cov hlab ntsha thiab tej zaum txawm tias kink. Qhov no ua rau nws nyuaj heev rau kev tso lub zais pa lossis stent, thiab kinking yuav tiv thaiv lub zais pa ntawm deflating kom raug, yog li ua rau muaj kev pheej hmoo rau tus neeg mob.

Raws li cov kev xav tau ntawm kev kho mob saum toj no, peb tuaj yeem txiav txim siab yooj yim:

Ib lub raj ntev txaus yog xav tau uas sib npaug txhua yam muaj zog thiab yoog raws​ - kom yooj yim pushability thiab du navigation los ntawm nkhaus.

Lub lumen sab hauv yuav tsum zoo nyob twj ywm undeformed​ - txhawm rau pab txhawb kom muaj kev nce nqi zais pa thiab deflation.

Nws yog qhov tseeb tias tsis muaj cov raj yas lossis cov hlau yooj yim tuaj yeem sib npaug cov ntsiab lus saum toj no. Qhov no yog thaum "tus pas nrig tshwj xeeb" yuav tsum tau hu ua kom tau raws li tus kws kho mob xav tau thiab cawm cov neeg mob hauv qhov xwm txheej tseem ceeb.

Bang! Tus "ncaj-Ib tug tub kawm" - Hypotube - nkag mus rau qhov chaw.

(Duab: Ntu dub yog lub Hypotube. Txawm hais tias qhov khoov yog me ntsis exaggerated, qhov no yog kwv yees li cas nws navigates hauv cov hlab ntsha.)

I. Hypotube yog dab tsi?

Tsis muaj phau ntawv txhais lus -style txhais rau Hypotube. Nyob rau hauv cov ntsiab lus, nws yog ib tug hlau raj uas undergoes tshwj xeeb ua kom muaj siab toughness thiab elasticity. Nws tuaj yeem kho tau ntau txoj hauv kev thiab tau siv dav hauv kev kho mob catheters.

Ib lub ntsiab lus uas tsis muaj ciam teb nruj feem ntau txhais tau tias nws cov ntawv thov tuaj yeem ua rau muaj kev hloov pauv tsis kawg.

(Duab: PTCA txheej txheem thiab stent implantation)

Los ntawm cov hlab ntsha coronary, los ntawm PTCA (Percutaneous Transluminal Coronary Angioplasty), Hypotube pib nkag mus rau qhov pom ntawm cov kws kho mob. Tau ntau xyoo, balloons tau hloov kho, cov raj yas tau hloov kho dua tshiab, tsis tau Hypotube - uas nyob ntawm 70% mus rau 80% ntawm tag nrho qhov ntev ntawm lub catheter - tseem tsis tau hloov pauv ntau."Ib qho classic los ntawm yug" yog kab tias cov ntsiab lus zoo tshaj plaws rau nws.

II. Rhuav Stereotypes: Lub Hypotube yog ntau tshaj li "304 Stainless Steel"

Raws li cov lus hais mus, "Dab tsi coj kev vam meej tuaj yeem coj tsis tau." Precisely vim hais tias nws yog classic heev, tau ntau xyoo neeg txoj kev nkag siab ntawm nws tau ua stereotypical: 304 stainless hlau khoom, siv nyob rau hauv PTCA, ib leeg -structured… thiab hais txog. Qhov no yog ib qho kev nkag siab tsis meej tag nrho ntawm Hypotube; nws lub peev xwm loj thiab muaj txiaj ntsig tau nyob ntsiag to hauv cov lus.

Ua ntej tshaj plaws, tsev neeg Hypotube yog qhov loj heev:

304 SS Hypotube UAS

Nitinol Hypotube

Hypodermic koob Tubing (Hypotube)

Laser-Txiav Hypotube

Thib ob, txawm tias tsuas yog hais txog cov ntaub ntawv lawv tus kheej, muaj ntau qhov tob:

Piv txwv li,304Vyog ib qho kev hloov kho evolution los ntawm304L, nrog kev txhim kho torsional tsis kam. Lwm qhov piv txwv yog qhov muaj zog kink tsis kam ntawm Nitinol hlau, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev taug qab cov hlab ntsha nrog ntau qhov khoov ntse.

Thaum kawg, ntau yam kev cai- txiav cov qauv tuaj yeem tsim los ntawm qhov xav tau. Los ntawm kev kho qhov tsis xws li kev txiav suab, qhov dav, thiab qhov zoo, qhov hardness thiab saj zawg zog tuaj yeem sib npaug rau cov phiaj xwm tshwj xeeb nrog precision.

III. Nthuav daim ntawv thov: Los ntawm Coronary mus rau Broader Fields

Hauv xyoo dhau los lossis ob xyoos dhau los, raws li Hypotube tau tshawb fawb thiab tsim tsis tu ncua, qee qhov kev xa khoom catheters thiab coj cov catheters hauv thaj chaw aortic thiab neurovascular tau pib sim siv nws los ntxiv lossis hloov cov raj yas. Qhov lawv muaj nuj nqis yog nws lub zog, toughness, thiab dav plasticity. Qhov no yog raws li kev tsim kho tshiab thiab tseem txiav txim siab txo nqi.

Tam sim no, siab -Hypotubes qhov tseeb yog qhov zoo tshaj plaws hauv tebchaws Ireland, nrog Creganna Medical yog lub tuam txhab sawv cev tshaj plaws. Hauv tsev, ntau lub lag luam uas muaj zog sib tsoo thiab txiav muaj peev xwm kuj tau tshwm sim, thiab lawv tau sib zog ua kom ncav cuag txoj hauv kev tshawb nrhiav Hypotubes.

IV. Xaus

Qhov zoo li yooj yim tab sis tsis tshua muaj tshwj xeeb Hypotube - nws lub peev xwm tau txuas ntxiv mus nrog rau kev txhim kho kev lag luam kho mob, pab tsim cov khoom tsim thiab kev siv tshuaj kho mob.

Peb ntseeg tias lub raj hlau yooj yim no yuav muaj tseeb tshaj tawm cov cua sov thiab lub yeeb koob ntawm kev taug kev ntawm kev kho mob.
