Covradiofrequency (RF) transseptal puncture koobyog qhov tseem ceeb precision ntsuas 配套 (kev txhawb nqa / khoom siv) rau kev cuam tshuam RF ablation zog tshuab. Koom tes tsim thiab tsim los ntawm Manners Technology hauv kev koom tes nrog Baylis Medical thiab Boston Scientific, nws yog tsim tshwj xeeb rau Transseptal Puncture (TSP) cov txheej txheem. Raws li lub cuab yeej tseem ceeb rau kev tsim kom muaj kev cuam tshuam tsawg kawg nkaus nkag mus rau sab laug atrium, nws tau hloov pauv tag nrho cov txheej txheem kho tshuab puncture phais. Hauv ntau txoj haujlwm sab laug- lub plawv cuam tshuam xws li atrial fibrillation (AF) ablation, sab laug atrial appendage (LAA) kaw, thiab mitral valvuloplasty, transseptal puncture yog thawj kauj ruam thiab tseem ceeb heev; qhov tseeb thiab kev nyab xeeb ntawm qhov puncture ncaj qha txiav txim siab qhov ua tiav thiab kev kwv yees ntawm tag nrho cov kev phais.

Ib txwm siv tshuab puncture koob cia siab rau cov lus qhia ntse rau mechanically tho lub septal cov ntaub so ntswg, yuav tsum tau muaj zog lub cev thaum lub sij hawm tus txheej txheem. Thaum cuam tshuam nrog cov txheej txheem anatomical nyuaj xws li thickened fossa ovalis, atrial septal aneuryms, los yog fibrotic nti, lawv muaj feem xyuam rau cov teeb meem loj xws li puncture tsis ua hauj lwm, cov ntaub so ntswg laceration, thiab lub plawv tamponade. Tsis tas li ntawd, cov txheej txheem no yog lub sijhawm-siv, koom nrog cov koob tshuaj fluoroscopy siab, thiab tso cov kev xav tau siab heev rau tus neeg teb xov tooj qhov kev paub dhau los. Nyob rau hauv sib piv, tus cwj pwm RF transseptal puncture koob tso tseg lub logic ntawm txhua yam brute - quab yuam puncture, cia siab rau es tsis txhob ntawm controllable RF pulse zog kom ua tiav pncturing meej. Nws yog yoog tau rau ntau yam nyuaj septal anatomies, txhim kho cov npoo ntawm qhov yuam kev hauv kev kho mob phais.

Cov qauv tsim tseem ceeb ntawm cov khoom no yog nws qhov sib npaug, atraumatic koob tip qauv. Tsis zoo li cov koob ntse ntse, nws tso cai rau kev hloov kho qhov chaw zoo yam tsis muaj khawb tawm ntawm lub plhaub thiab lub dilator thaum lub sij hawm txheej txheem, yog li tshem tawm cov cim ntawm cov khib nyiab yas thiab hauv paus tsis txhob muaj kev pheej hmoo ntawm cov teeb meem embolic. Cov khoom siv kev kho mob -qib 304 thiab 305 stainless hlau, tuav ib tug ruaj khov hardness ntawm HRC 22-25, ntsuas cov qauv toughness thiab puncture stability. Muaj nyob rau hauv qhov tseeb diameters ntawm 0.6 hli thiab 0.7 hli, nws ua tau raws li qhov kev xav tau ntawm kev phais ntawm cov neeg laus thiab cov neeg mob, thaum tus qauv 6.5 hli ua hauj lwm ntev aligns nrog mainstream interventional phais kev khiav hauj lwm systems.

Raws li tus qauv kev kho mob precision ntsuas, tus cwj pwm RF transseptal puncture koob ua raws li cov qauv tsim khoom nruj me ntsis thoob plaws hauv nws lub neej. Ua tiav siv cov khoom siv siab -cov neeg Nyij Pooj Nyij Pooj Cincom R04, nws qhov ntev ntev yog tswj tsis pub dhau ± 0.01 hli. Nruab nrog cov cim radiopaque, nws tso cai rau kev pom meej meej hauv cov duab kos duab, ua rau cov txheej txheem puncture pom thiab tswj tau. Nrog nws cov txiaj ntsig zoo thiab muaj txiaj ntsig zoo, cov cuab yeej no tau dhau los ua cov cuab yeej nyiam rau cov txheej txheem kev cuam tshuam ntawm lub plawv, tsav kev txhim kho ntawm TSP kev phais mus rau qis dua, kev ua tau zoo dua, thiab kev tsim qauv.
