Cov txheej txheem BADDASS yog cov txheej txheem thrombectomy ua ke uas tau npaj tseg rau xyoo 2019. Qhov ntawd yog, daim ntawv qhia zais pa nrog cov tho qhov loj hauv qhov chaw nkag catheter nrog dual aspiration nrog stent-retriever raws li txoj hauv kev rau thrombectomy. Cov txheej txheem ua haujlwm ntawm BADDASS thev naus laus zis yuav tsum tau tshem tawm cov thrombectomy stent thiab cov catheter nruab nrab ntawm tag nrho, uas ua rau tsis muaj txiaj ntsig ntawm txhua yam khoom siv hauv BADDASS technology. Rau cov mos mos thrombus nrog me me load, thaum lub stent mus txog rau hauv cov hlab ntsha loj thaum lub sij hawm tshem tawm cov txheej txheem, lub thrombus embedded nyob rau hauv lub stent yog ib qho yooj yim mus poob tawm vim lub expansion ntawm lub stent retriever thiab nro ntawm cov lus qhia hlau ntawm stent. . Rau cov neeg mob no, nws yuav tsim nyog siv lub thrombectomy stent kom rub tawm ntawm lub catheter nruab nrab, ua raws li qhov kev xav ntawm qhov nruab nrab catheter ntawm tib txoj hauj lwm. Yog hais tias lub thrombus tau raug tshem tawm ntawm lub stent, cov thrombus fragments txiav tawm los ntawm lub ntsis ntawm lub catheter yuav muab rho tawm los ntawm nruam aspiration ntawm lub intermediate catheter. Yog hais tias lub thrombus tsis tau muab tshem tawm, lub intermediate catheter txuas mus rau lub thrombus, uas yog sib npaug rau nruam stent thiab aspiration thrombectomy. Tsis tas li ntawd, cov txheej txheem BADDASS yog qhov nyuaj tshaj li tus qauv SWIM txheej txheem. Qee tus neeg mob tuaj yeem ncua qhov kev rov qab los ntawm qhov distal perfusion. Thiab tag nrho cov kab mob thrombectomy yog kim, uas yog ib txoj hauv kev kim rau qee cov neeg mob. Txawm li cas los xij, rau cov neeg mob nyuaj nrog lub nra hnyav, BADDASS thev naus laus zis tuaj yeem cuam tshuam nws tus kheej zoo.
Cov txheej txheem BADDASS suav nrog ntau yam khoom, suav nrog microcatheter, kev qhia zais pa, thiab stent-retriever. Thawj kauj ruam yog txhawm rau txhim kho lub microcatheter mus rau qhov chaw ntawm cov hlab ntsha, siv cov kev taw qhia ntawm lub sijhawm tiag tiag. Thaum lub microcatheter nyob rau hauv qhov chaw, ib daim ntawv qhia balloon yog tom qab ntawd tshaj lub microcatheter. Daim ntawv qhia balloon yog inflated los tiv thaiv cov ntshav ntws thiab tsim kom muaj lub platform ruaj khov rau cov kauj ruam tom ntej, uas cuam tshuam nrog kev nce qib ntawm qhov loj bore distal nkag catheter.
Qhov loj bore catheter yog tsim los muab dual aspiration, uas txhim kho lub peev xwm tshem tawm cov hlab ntsha ntawm lub hom phiaj. Tom qab lub catheter nyob rau hauv txoj hauj lwm, ib tug stent retriever yog siab dhau los ntawm lub catheter thiab muab tso rau thoob plaws hauv lub clot. Tus stent-retriever ces ntes cov hlab ntsha, thiab cov ntawv qhia zais pa yog deflated, tso cai rau cov ntshav rov pib dua.
Ib qho txiaj ntsig tseem ceeb ntawm BADDASS cov txheej txheem yog tias nws tso cai rau kev tshem tawm ntau dua thiab ua tau zoo ntawm cov hlab ntsha. Qhov no yog qhov tseem ceeb vim tias kev tshem tawm tsis tiav ntawm cov hlab ntsha tuaj yeem ua rau muaj kev raug mob reperfusion, uas tuaj yeem ua rau cov neeg mob hnyav zuj zus. Tsis tas li ntawd, kev siv lub balloon qhia thiab dual aspiration catheter txo qhov kev pheej hmoo ntawm distal embolization, uas tuaj yeem thaiv cov hlab ntsha me hauv lub hlwb thiab ua rau muaj kev puas tsuaj ntxiv.
Lwm qhov zoo dua ntawm BADDASS cov txheej txheem yog tias nws tuaj yeem siv los ua tus txheej txheem rau cov neeg mob mob stroke. Qhov no txhais tau hais tias nws tuaj yeem siv tau sai los ntawm cov kws kho mob uas tau kawm tiav yam tsis tas yuav muaj kev cob qhia tshwj xeeb lossis khoom siv ntxiv. Qhov no tso cai rau kev kho mob sai thiab ua tau zoo dua, uas tuaj yeem cuam tshuam loj rau cov neeg mob tau txais txiaj ntsig.
