Aspiration Catheter
Hauv kev mob stroke ischemic stroke (AIS), mechanical thrombectomy tau muab faib ua ob qho kev qhia loj. Ib qho yog thrombectomy los ntawm stent, uas yuav tsum tau siv cov thrombectomy stent retriever. Lwm qhov yog kom tshem tawm cov kab mob hauv cov hlab ntsha ncaj qha los ntawm kev nqus catheter. Kev kho mob Aspiration yog ib qho kev siv tshuab uas tau tsim sai heev nyob rau xyoo tas los no. Qee lub sij hawm lub aspiration catheter kuj tseem ua ke nrog stent retrieval kom tshem tawm thrombus. Xyoo 2013, Xib Fwb Turk thiab lwm tus thawj zaug tau thov ADAPT (A Direct Aspiration First-Pass Technology) thev naus laus zis, thiab yog li cov thev naus laus zis ntshiab thrombus aspiration tau yug los, thiab ntau hom thrombus aspiration catheters tau tsim los ntawm cov tuam txhab loj. Niaj hnub no, kev siv thrombus aspiration catheters rau kev kho mob ntawm ischemic stroke nyob rau hauv lub tebchaws United States yog piv rau kev siv thrombectomy stent retriever.
Yam Khoom Taw Qhia
Cov qauv ntawm thrombus aspiration catheters tuaj yeem raug cais raws li lawv cov khoom siv, thiab tseem tuaj yeem ua qhov txawv raws li qhov sib txawv ntawm txhua ntu ntawm lub catheter.
1. Kev faib cov khoom ntawm thrombus aspiration catheter: Catheter lub rooj ntxiv rau txheej txheej polymer ntxiv rau cov hlau braid / coil-pob nruab nrab txheej ntxiv rau cov txheej txheem polymer sab hauv ntxiv rau cov khoom siv hluav taws xob hauv lub nplhaib ntxiv rau lub nplhaib distal ntxiv rau sab nraud polymer txheej txheej nrog hydrophilic txheej.
2. Cov qauv kev faib tawm ntawm thrombus aspiration catheters: catheter proximal support section ntxiv catheter intermediate transition section ntxiv rau catheter distal soft section
Cov haujlwm ntawm txhua ntu yog raws li hauv qab no:
Kev txhawb nqa qhov kawg ntawm lub catheter: Nws yuav tsum muaj kev khoov zoo thiab kev txhawb nqa, thiab muab kev txhawb nqa zoo rau lub catheter.
Kev hloov pauv nruab nrab ntawm lub catheter: Nws yuav tsum muaj lub zog tsim nyog thiab hloov pauv kom zoo dua txuas rau qhov kev txhawb nqa qhov kawg thiab qhov chaw mos distal, yog li txhawb nqa lub zog thawb ntawm ntu kev txhawb nqa kom zoo dua mus rau qhov kawg ntawm qhov kawg. lub catheter.
Qhov muag muag ntawm qhov kawg ntawm lub catheter: Nws yuav tsum tau ua kom yooj yim thiab pom qhov muag, uas yog qhov zoo rau kev hla ntawm cov hlab ntsha intracranial.
Cov khoom lag luam kev lag luam
Hauv 2008, ib lub tuam txhab Asmeskas tau tsim lub tshuab nqus pa nrog lub taub sab hauv ntawm 0.026 nti. Nws kuj yog ib tug ntawm cov thawj manufacturers tsim intracranial thrombus aspiration catheter khoom. Judging los ntawm cov series ntawm aspiration catheters launched los ntawm ib co tuam txhab uas muag nyob rau hauv xyoo tas los no, nrog rau kev nce qib ntawm cov ntaub ntawv thiab kev txhim kho nyob rau hauv technology, qhov luaj li cas ntawm aspiration catheters tau maj mam ua loj. Nyob rau hauv cov nqe lus ntawm aspiration nyhuv, nws yog feem ntau ntseeg hais tias qhov loj ntawm lub puab txoj kab uas hla ntawm catheter, qhov zoo dua lub aspiration nyhuv-Biger yog qhov zoo tshaj plaws!
