Tam sim no, muaj plaub txoj hauv kev tseem ceeb ntawm coil detachment: thermal melting detachment, electrolysis detachment, mechanical detachment, and water detachment, of which electrolytic detachment is the detachment method with the longest development time. Txawm li cas los xij, txij li feem ntau ntawm cov xov hlau sib txuas siv rau electrolytic detachment yog ua los ntawm cov hlau tsis muaj steel, nws yuav siv sij hawm ntev rau kev ua kom tiav, qhov tshwm sim ntawm cov teeb meem xws li tsis muaj peev xwm detach yog siab, thiab detachment efficiency thiab stability yog tsawg, uas tseem muaj. tsis tuaj yeem paub qhov zoo tshaj plaws detachment nyhuv ntawm stability thiab high efficiency. Yog li lwm txoj kev detachment tau tsim tom qab.
1. Electrolytic detachable coils feem ntau siv cov ncej zoo thiab tsis zoo ntawm cov tso tawm kom nkag mus rau hauv cov ntshav ntawm tib neeg lub cev los ntawm cov hlau rods lossis hlau koob, thiab tom qab hluav taws xob, cov hlau xaim siv los txuas cov coils thiab cov hlau zoo yog electrolyzed nyob rau hauv. ntshav ua hlau ions, thiab tom qab ntawd cov hlau hlau tawg kom ua tiav cov nyhuv tso tawm. Qhov tsis zoo ntawm txoj kev no yog tias qhov welded yuav tsis sib npaug tom qab lub vuam hluav taws xob txias, thiab nws yog ib qho yooj yim los tsim ib qho hluav taws xob siab, uas yuav ua rau lub sij hawm tsis yooj yim tswj thaum lub coil tawm ntawm microcatheter.
2. Thermal melting detachable coil los ntawm fusing seem kev sib txuas ntawm lub laub pas nrig thiab lub kauj los ntawm cov cua sov kauj kom paub txog cov nyhuv detachment ntawm lub kauj. Nws tsim hluav taws xob los ntawm hluav taws xob, thiab thaum tshav kub mus txog ib theem, lub thermal fuse yog tshuab kom paub txog qhov tso tawm ntawm lub kauj. Txoj kev no yuav tsum muaj kev qhia txog hluav taws xob tam sim no, xov hlau thiab electrodes, thiab lwm yam, thiab cov pa luam yeeb yuav raug tsim thaum tshav kub kub, uas yuav ua rau muaj kev puas tsuaj rau tib neeg lub cev.
3. Mechanical detachable coil ua tiav qhov kev tso tawm los ntawm cov txheej txheem tshwj xeeb thiab cov cuab yeej ua haujlwm. Txoj kev tseem ceeb tam sim no yog hom ferrule. uas yog, los ntawm ib tug movable txuas pas nrig nrog ib tug spherical kawg, thawj kawg ntawm uas yog txuas nrog lub kauj. Lub detachment hlau thiab lub movable txuas pas nrig yog sib sau ua ke thiab muab tso rau hauv tus xa catheter ua ke, thiab cov xaim tso tawm raug tshem tawm kom paub qhov kev tso tawm ntawm lub kauj.
4. Dej detachable coil system muaj xws li ib tug high-pressure injector, ib tug coil xa tube thiab ib tug liab qab platinum kauj. Lub detachment ntawm lub kauj yog ua tiav los ntawm kev txhaj tshuaj hnyav rau hauv lub raj xa dej kom yaj nws. Sib txawv ntawm electrolysis detachable coil, cov yam ntxwv tseem ceeb yog: thaum lub coil tso tawm rau hauv lub aneurysm, nws yog ib txwm coiled raws phab ntsa aneurysm ntawm sab nraud mus rau sab hauv. Lub nplhaib yog mos, thiab nws yog randomly nyob rau hauv peb qhov ntev thaum tso tawm, uas tuaj yeem ua tau zoo dua rau cov duab ntawm qhov aneurysm. Txoj kev no muaj teeb meem ntawm kev tso tawm tsis ruaj khov, thiab kev txhaj tshuaj hnyav yog ib qho yooj yim los ua kom lub siab ntawm cov hlab ntsha, thiab yog tias tus nqi ntawm cov kuab tshuaj tsis txaus thiab tsis tuaj yeem ncav cuag txoj haujlwm uas lub kauj yog tso tawm.
