Hais txog qhov mob cov ntsiab lus hauv kev kho mob neurointerventional, Distal access catheter tau ua tiav ntau yam kev ua haujlwm hauv cov qauv tsim thiab kev ua haujlwm tsis zoo, nrog rau txhua lub thev naus laus zis sib piv cov kev xav tau kho mob:
1. Ultra- hloov pauv qhov kawg ntawm qhov kawg + kev txhawb nqa gradient: Ntsuas kev nkag tau yooj yim thiab ruaj khov
• Ultra- hloov pauv qhov kawg ntawm qhov kawg: Qhov kawg ntawm qhov kawg siv kev kho mob- qib ultra- cov khoom siv polymer hloov tau nrog lub vojvoog khoov kom tsawg raws li qhov chaw kho mob tseem ceeb. Ua ke nrog kev taug qab zoo heev, nws tuaj yeem yooj yim hla txoj hauv kev nyuaj xws li ntu carotid siphon thiab basilar artery tortuosity, ncaj qha mus txog qhov mob hauv nruab nrab xws li M3 ntu ntawm nruab nrab cerebral artery thiab P3 ntu ntawm vertebrobasilar artery, txo cov hlab ntsha thiab kev pheej hmoo ntawm cov hlab ntsha.
• Coil + braided composite structure: Ib qho tshiab "coil + braided" composite reinforcement qauv tsim cov gradient txhav tis-proximal reinforcement muab kev txhawb zog, zoo tiv thaiv cov tshuaj tiv thaiv los ntawm vascular tortuosity thiab tiv thaiv cov cuab yeej txav los yog "retraction"; qhov nruab nrab -section maj mam hloov mus rau ib qho kev hloov pauv hloov pauv ntawm qhov kawg ntawm qhov kawg, sib npaug ntawm kev sib tw nrog lumen ruaj khov, ua tiav ob qhov zoo ntawm "txoj kev txhawb nqa tsis muaj kev cuam tshuam thiab hloov tau yooj yim yam tsis muaj jamming."
2. 0.088" Ntxiv -Looj Lumen: Redefining Access Delivery Efficiency
Hais txog qhov mob cov ntsiab lus ntawm "device compatibility" thiab "thrombus tshem tawm" nyob rau hauv cov txheej txheem xws li mechanical thrombectomy thiab aneurysm embolization, peb qhia ib qho ntxiv -loj 0.088-inch (kwv yees li 2.24mm) puab txoj kab uas hla. Qhov chaw hla ntu ntawm lub lumen tau nce ntau dua piv rau cov pa catheters (piv txwv li, 54% loj dua li 0.071-nti catheter), nqa peb cov txiaj ntsig zoo:
• Kev tshem tawm Thrombus muaj txiaj ntsig zoo: Txhawb nqa "kev xav ncaj qha" thev naus laus zis. Qhov ntxiv -loj lumen tso cai rau kom tiav kev noj cov thrombus, txo qhov kev pheej hmoo ntawm thrombus fragmentation, kev txhim kho thawj zaug -pass effect (FPE), thiab txo lub sij hawm recanalization;
•Distal Flow Reversal: Lub lumen loj dua tuaj yeem ua kom muaj txiaj ntsig zoo dua qhov kev thim rov qab, txo qhov kev pheej hmoo ntawm cov teeb meem embolic;
•Multi-Kev sib raug zoo ntawm cov cuab yeej: Yooj yim haum rau ntau yam khoom siv kho mob xws li thrombectomy stents, microcatheters, thiab coils ib txhij, tshem tawm qhov xav tau rov qab hloov pauv thiab txhim kho kev phais kom zoo.
3. Dedicated Fit rau Txoj Kev Radial: Qhov Kev Xaiv Zoo Tshaj Plaws rau Kev Kho Mob Tsawg
6F-R series qauv (xws li 6F-95R, 6F-105R, thiab lwm yam) yog tsim tshwj xeeb rau cov hlab ntsha radial, nrog rau qhov ntev ntawm 95-125cm thiab sab hauv txoj kab uas hla ntawm 0.071 ntiv tes. Lawv zoo kawg nkaus haum rau 6F radial artery sheath, daws cov teeb meem ib txwm muaj ntawm kev nkag tsis tau ntev thiab kev txhawb nqa tsis txaus cuam tshuam nrog txoj hauv kev radial:
• Txo kev raug mob thiab teeb meem: Txoj kev radial kom tsis txhob muaj kev pheej hmoo ntawm puncture-txog los ntshav thiab hematoma cuam tshuam nrog txoj hlab ntsha femoral, ua rau nws tshwj xeeb tshaj yog rau cov neeg mob rog, cov uas tau txais kev kho mob anticoagulation, lossis cov neeg muaj mob vascular tsis zoo;
• Nyob Hauv Tsev Kho Mob Shorter: Qhov cuam tshuam me me tso cai rau kev rov qab ua haujlwm sai dua, nrog lub tsev kho mob nruab nrab nyob ntau dua 30% luv dua li txoj hauv kev femoral, txhim kho cov neeg mob kev paub thiab txo cov nqi pw hauv tsev kho mob;
•Operational Flexibility: Tau tshaj 6F guiding catheters nyob rau hauv neurointerventions, tso cai rau kev ruaj ntseg mus rau distal intracranial lesions thiab muab txhim khu kev qha kev pab txhawb rau transradial neurointerventional phais.
4. Versatile Compatibility: Npog Ntau Hom Kev Kho Mob Neurointerventional
Cov khoom lag luam dav dav, suav nrog ntau qhov sib txawv sab nraud suav nrog 5F, 6F, thiab 8F, nrog rau qhov ntev zoo li ntawm 95cm txog 132cm, yoog tau rau ntau txoj kev nkag mus thiab qhov chaw mob:
• 5F Series (piv txwv li, 5F-105/115/125/132): Sab hauv txoj kab uas hla 0.056 ntiv tes, tau tshaj 6F guiding catheters, haum rau distal me me hlab ntsha tawg (xws li, M2-M3 ntu thrombosis, microaneurysms);
•6F-S Series (piv txwv li, 6F-115S/125S/132S): Sab hauv txoj kab uas hla 0.073 ntiv tes, sib xws nrog 6F ntev sheaths, 8F guiding catheters, los yog balloon guiding catheters, haum rau cov teeb meem nyuaj xws li mob me me mus rau hnyav stenosis thiab wide-urys
• 8F Series (piv txwv li, 8F-95/105/115): Sab hauv txoj kab uas hla 0.088 ntiv tes, sib xws nrog 8F... Lub sheath yog tsim los tshwj xeeb rau cov neeg kho tshuab thrombectomy thiab tshem tawm cov thrombi loj, ua rau nws nyiam ntaus ntawv rau kev kho mob ntawm ischemic stroke.
