Pushability Performance Ntawm Microcatheter Ncej

1. Kev lag luam Pain Points

Pushability tsis txaus yog qhov tseem ceeb txwv qhov kev xa khoom sib sib zog nqus ntawm microcatheter shafts hauv kev phais me me. Ultra-fine micro shafts yog qhov yooj yim rau axial compression deformation thiab distal retraction nyob rau hauv propulsion quab yuam, tsis muaj peev xwm xa tau zoo thrust mus rau qhov kawg ntawm qhov txhab. Hauv kev cuam tshuam ntawm vascular thiab nqaim lumen, kev ua haujlwm tsis zoo ua rau muaj teeb meem hauv kev xa cov cuab yeej cuam tshuam rau lub hom phiaj txoj haujlwm, yuav tsum tau rov ua dua thiab ua kom lub sijhawm phais ntev. Ordinary micro shafts muaj unbalanced pushability thiab saj zawg zog: overly saj zawg zog shafts tsis axial rigidity thiab yog ib qho yooj yim rau vau thaum lub sij hawm propulsion, thaum overly rigid shafts tsis zoo vascular adaptability thiab yooj yim puas ilv micro- cov phab ntsa. Qhov kev tsis sib haum xeeb no tau txwv ntev ntev rau kev siv cov microcatheters hauv qhov sib sib zog nqus thiab kev cuam tshuam zoo.

2. Txoj Cai Ua Haujlwm

Lub pushability ntawm microcatheter shafts nyob ntawm axial structural rigidity ntawm laser -txiav hypotubes thiab cov khoom compression kuj. Qhov tsim nyog qauv laser txiav qauv khaws cia lub axial nruam nruam lub moj khaum ntawm lub micro ncej, uas muaj peev xwm tiv taus axial compression deformation thiab stably kis proximal propulsion quab yuam mus rau distal kawg. Segmented gradient cutting design realizes proximal dense rigid structure and distal sparse flexible structure: the proximal rigid segment provides strong axial pushability support, while the distal flexible segment ensures vascular fitting adaptability. Siab - lub zog kho mob stainless hlau thiab cov ntaub ntawv alloy muaj qhov zoo heev compression tsis kam, tsis txhob muaj ncej dabtsi yog khoov thiab vau nyob rau hauv thrust. Qhov sib txuam ntawm cov qauv rigidity thiab cov khoom siv lub zog paub txog cov organic sib koom ua ke ntawm lub zog pushability thiab siab yooj rau micro shafts.

3. Kev faib ua feem

Raws li kev txhawb nqa kev ua tau zoo thiab kev tsim qauv, microcatheter shafts tau muab faib ua plaub qhov xwm txheej- raws li hom. Ua ntej, siab -rigidity pushable shafts: sparse interrupted txiav qauv, muaj zog axial compression kuj, haum rau sib sib zog nqus ntev -nyob deb micro- nkoj xa khoom. Thib ob, sib npaug thawb-kev ua kom yooj yim shafts: tsis tu ncua muab kauv txiav, sib npaug thrust kis tau tus mob thiab khoov kev ua tau zoo, muaj feem xyuam rau feem ntau micro- kev cuam tshuam. Thib peb, distal saj zawg zog pushable shafts: gradient kuj sib txawv txiav, proximal siab rigidity thiab distal siab yooj, zoo tagnrho rau ntau -bending sib sib zog nqus lesion xa. Plaub, siab -lub zog alloy thawb ncej: ua los ntawm 17-7PH thiab L605 alloy, ultra-siab compression resistance, mob siab rau siab-tsis kam nqaim lumen cuam tshuam scenarios.

4. Cov lus qhia ua haujlwm zoo

Xaiv qhov sib txuam micro shafts raws li kev phais qhov tob thiab vascular kuj. Rau kev sib sib zog nqus ntev -kev cuam tshuam deb, ua qhov tseem ceeb siab -rigidity cuam tshuam cov ncej kom muaj zog txaus. Rau ntau-khoov cov hlab ntsha, txais yuav gradient balanced push-flexion shafts kom tsis txhob shaft vau thaum ua kom cov khoom xa tuaj. Thaum lub sij hawm propulsion ua hauj lwm, tuav ruaj khov thiab zoo ib yam thrust, tsis txhob cia li dhau quab yuam ua rau lub zos ncej deformation. Kho propulsion ceev raws li vascular kuj hloov, koom tes nrog qeeb rotation kom txo tau pem hauv ntej kuj. Ua ntej kev phais, sim cov axial compression kev ua tau zoo ntawm cov ncej kom tsis muaj deformation nyob rau hauv rated thrust.

5. Kev paub txog kev lag luam

Cov ntaub ntawv thov kev kho mob tau lees paub tias laser- txiav gradient micro shafts txhim kho pushability los ntawm 43% piv nrog cov tsoos tsho micro leeg, thiab qhov ua tiav ntawm ib qho - lub sij hawm sib sib zog nqus xa tuaj 38%. High-rigidity cuam tshuam kev txiav cov ncej zoo daws qhov teeb meem ntawm kev xa khoom nyuaj hauv siab -tsis kam nqaim lumens, ua rau lub sijhawm ua haujlwm luv luv. Gradient pushable shafts zoo kawg nkaus sib npaug kev ruaj ntseg thiab vascular kev nyab xeeb, txo vascular phab ntsa puas los ntawm nruj propulsion. Muaj batch ntau lawm ua pov thawj tias tus qauv txiav qauv tsim kom muaj kev ruaj ntseg ntawm cov khoom batch, nrog rau kev soj ntsuam zoo ib yam.

6. Cov ntsiab lus & Txhim kho

Pushability yog qhov kev ua haujlwm yooj yim ntawm microcatheter shafts rau kev xa khoom. Ib txwm niaj hnub qauv shafts tsis tuaj yeem sib npaug thawb rigidity thiab khoov yooj yim, ua rau muaj kev xa khoom nyuaj hauv kev phais nyuaj. Laser gradient txiav thev naus laus zis hauv paus daws qhov kev tsis sib haum xeeb los ntawm segmented structural optimization, paub txog qhov sib txawv ntawm kev ua tau zoo sib xws ntawm kev sib tw propulsion thiab distal navigation. Tam sim no, cov phiaj xwm kev txhawb nqa kev ua kom zoo tshaj plaws yog qhov paub tab, tab sis qhov kev hloov pauv ntawm kev xa khoom nyob rau hauv qhov siab siab -tsis kam nqaim lumen tej yam kev mob tseem xav tau kev tsim qauv ntxiv.

7. Cov lus qhia txog kev txhim kho yav tom ntej

Yav tom ntej pushability optimization yuav tsom mus rau adaptive thrust adjustment thiab huab scenario adaptation. Tsim cov kev txawj ntse gradient txiav cov qauv uas tuaj yeem kho axial rigidity raws li vascular kuj. Ua kom zoo siab - lub zog sib xyaw cov qauv siv los txhim kho cov compression tsis kam ntawm ultra-fine micro ncej. Tsim kom muaj kev txhawb nqa kev sib tw cov qauv sib xws rau vascular tsis kam ua kom zoo dua cov khoom xaiv tshwj xeeb. Muab cov ntaub ntawv phais loj rau iterate cov txheej txheem tsis, ntxiv txhim kho lub peev xwm sib sib zog nqus thiab ruaj khov ntawm microcatheter shafts hauv cov txheej txheem kev cuam tshuam zoo.
