Raws li cov cuab yeej ntsuas kev ua haujlwm siab, qhov ntsuas qhov tseeb ncaj qha txiav txim siab qhov tshwm sim ntawm kev phais. Leveraging ib tug standardized, refined, thiab kev parameter system, tus cwj pwmRF transseptal puncturekoob tsim qhov sib txawv qhov zoo ntawm qhov ntev xws li qhov loj me, kev ua haujlwm ntawm lub cev, thiab kev ua haujlwm raug. Precisely txuam thoob ntiaj teb mainstream cardiac interventional phais kev khiav hauj lwm qauv, nws stands raws li ib tug kev lag luam parameter benchmark khoom.

Hais txog qhov tseem ceeb ntawm qhov tsis sib xws, cov khoom lag luam nta ob - cov kab lus qhia tshwj xeeb: 0.6 hli thiab 0.7 hli meej npog cov kev xav tau ntawm kev phais ntawm tag nrho cov pej xeem. 0.6 mm ultra- nyias specification yog haum rau cov menyuam yaus, cov neeg mob me me, thiab cov kev phais mob me me, txo cov nqaij mos. Lub 0.7 hli cov lus qhia tshwj xeeb siv rau cov neeg laus cov kev kho mob niaj hnub, ntsuas qhov kev ruaj ntseg thiab kev phais kom zoo. Kev sib koom ua ke 6.5 hli tus qauv ua haujlwm ntev yog sib xws nrog qhov loj me ntawm cov ntaub qhwv lub ntsiab, dilators, thiab cov cuab yeej cuam tshuam, tsis tas yuav hloov kho lossis hloov kho ntxiv, yog li muab kev sib raug zoo heev.

Nyob rau theem precision parameter, tag nrho qhov ntev ntawm cov khoom yog nruj me ntsis tswj nyob rau hauv ± 0.01 hli, deb tshaj cov qauv kev lag luam. Lub cev rab koob nta cov tuab tuab thiab cov lus qhia meej symmetry, ua kom muaj zog sib npaug thaum lub sijhawm sib tsoo thiab qhov tseeb qhov chaw tsis muaj qhov sib txawv. Lub machining angular kam rau ua yog tswj nyob rau hauv 0.1 degree, kom ntseeg tau qhov tseeb fixation ntawm RF lub zog emission lub kaum sab xis. Qhov no tau lees paub lub zog tsom rau ntawm qhov taw tes puncture, tiv thaiv lub zog tawg thiab kub hnyiab rau cov ntaub so ntswg ib puag ncig, yog li ua tiav lub hom phiaj, qhov tseeb puncture.

Lub cev ua haujlwm tsis zoo yog qhov zoo heev. Kev cia siab rau qhov txias- txheej txheem ua haujlwm ntawm 304/305 kev kho mob stainless hlau, lub hardness yog ruaj khov nyob rau hauv lub golden HRC 22-25 ntau yam. Qhov no parameter zoo kawg nkaus sib npaug rigidity thiab toughness, daws cov teeb meem ntawm cov mos koob khoov thiab qhov chaw tsis raug, thaum tsis txhob muaj qhov tsis xws luag ntawm high-hardness koob ua nkig, nquag tawg, thiab yooj yim tearing cov ntaub so ntswg. Nws yog tsim rau ntau yam nyuaj transseptal puncture scenarios, nrog rau cov thickened, fibrotic, thiab aneurysmal hom.

Cov txheej txheem txhawb nqa tsis yog sib npaug. Lub machined nto roughness yog Ra < 0.4 μm, thiab tom qab electropolishing, koob taub hau bevel roughness poob mus rau qis li Ra 0.25 μm, ua tiav daim iav kho mob -zoo li tiav. Qhov no tshem tawm cov burrs, micro- tawg, thiab khib nyiab seem. Nyob rau tib lub sijhawm, nws tau nruab nrog cov txheej txheem radiopaque marker bands, muab cov duab meej meej thiab qhov tseeb qhov chaw, ua kom haum rau ntau yam kev cuam tshuam cov duab navigation systems. Cov txheej txheem tiav no tau raug kuaj xyuas tau zoo rau kev ua haujlwm ruaj khov thiab kev hloov pauv dav dav. Piv nrog rau cov khoom zoo sib xws, nws qhov tseeb, kev nyab xeeb, thiab kev sib raug zoo yog nyob rau theem kev lag luam.
