Ntsiab lus: Kev Kho Mob Stainless Hlau; Radiofrequency Transseptal Needle Chaw tsim tshuaj paus

Nyob rau hauv cov cuab yeej precision uas yog lub xov tooj cua zaus (RF) transseptal koob, cov khoom xaiv nteg lub hauv paus rau kev txhais nws cov kev txwv kev ua haujlwm. Cov tawv tawv heev (0.6-0.7 mm inch), nws yuav tsum tau muab ib txhij xa cov khoom siv zog tshwj xeeb, kev qaug zog zoo dua, biocompatibility zoo heev, thiab ruaj khov hluav taws xob conductivity. Kev kho mob austenitic stainless hlau-tshwj xeeb tshwj xeeb yog kho304 thiab 305 qib- tawm los ua qhov kev xaiv zoo tshaj plaws rau daim ntawv thov tseem ceeb no, ua tsaug rau nws cov khoom sib npaug thiab zoo heev. Rau cov neeg tsim khoom, kev nkag siab tob tob thiab paub txog cov yam ntxwv ntawm cov khoom no yog lub peev xwm tseem ceeb uas tsav cov khoom tsim los ntawm kev tsim khoom loj.

Vim li cas 304/305 Stainless Hlau?

304 stainless hlau (06Cr19Ni10)yog ib qho ntawm feem ntau siv kho mob stainless steels, nrog ntev - lub sij hawm soj ntsuam validation paub meej tias nws zoo heev corrosion kuj, formability, thiab biocompatibility.305 stainless hlau (06Cr18Ni12)nta cov ntsiab lus npib tsib xee ntau dua thiab ua haujlwm qis dua - tus nqi hardening, ua kom zoo dua ductility thaum lub sij hawm ua hauj lwm txias xws li sib sib zog nqus nqus thiab spinning. Rau transseptal koob tubing uas dhau los ua haujlwm txias (xws li, kos duab, ncaj) kom ua tiav qhov ntev thiab tawv, 305 stainless hlau muaj qhov ua tau zoo dua qhov rais.

Manufacturers xaiv ob cov ntaub ntawv no thiab txhim khu lawv hardness rauHRC 22–25los ntawm kev ua haujlwm hardening, ib qho kev xaiv uas tau tsav los ntawm kev kho mob nruj heev:

Tsim nyog axial rigidity thiab khoov lub zog: Raws li rab koob mus txog ntev, nkhaus tus me nyuam sheaths mus txog lub plawv, nws yuav tsum tiv thaiv yas dabtsi yog khoov los yog kinking. Nws yuav tsum muaj peev xwm txaus "them" kom raug xa mus rau tus neeg teb xov tooj tswj lub zog mus rau qhov kawg. Tsis tas li ntawd, thaum lub sij hawm RF xa hluav taws xob, lub koob lub cev yuav tsum nyob ruaj khov los tiv thaiv kev co lossis deformation los ntawm cuam tshuam lub zog tsom. Ua hauj lwm- hardened 304/305 stainless hlau muab qhov tseem ceeb ntawm cov qauv rigidity.

Precise dimension stability thiab machinability: Lub koob lub siab slenderness xav tau nruj kam rau ua (± 0.01 hli). Stainless hlau qhov zoo heev machinability enables micron - nplai tig thiab drilling ntawm precision tshuab cuab yeej zoo li Citizen R04, kom ntseeg tau ntev - lub sij hawm seem stability yam tsis muaj qhov tseem ceeb deformation los ntawm sab hauv kev ntxhov siab tso tawm.

Superior qaug zog kuj: Txawm hais tias ib qho - siv cov cuab yeej siv, rab koob tuaj yeem tiv taus cov kab mob micro- kev ntxhov siab los ntawm lub plawv dhia thiab catheter manipulation thaum phais. Stainless hlau lub siab qaug zog lub zog guarantees kev ntseeg siab nyob rau hauv nws luv luv siv voj voog.

Stable hluav taws xob thiab thermal conductivity: Raws li cov khoom siv hluav taws xob rau RF, cov khoom siv koob yuav tsum ua kom pom tseeb, cov khoom siv hluav taws xob zoo ib yam kom ntseeg tau tias muaj zog, ruaj khov hloov pauv ntawm lub tshuab hluav taws xob mus rau lub taub electrode. Nrog nruab nrab resistivity, stainless hlau yog cov khoom siv electrode zoo tagnrho. Nws cov thermal conductivity kuj ua kom yooj yim rau cov cua sov sai sai thaum lub sij hawm luv luv ntawm lub zog xa khoom, tiv thaiv kev kub ntxhov hauv cheeb tsam ntawm rab koob lub cev.

The Blunt, Atraumatic Tip: Fusion of Materials Science thiab Design Aesthetics

Lub RF transseptal koob lub ntsiab lus tseem ceeb -nwsblunt, atraumatic lub taub hau- stands in stark contrast to the sharp point of tsoos mechanical transseptal needles. Qhov kev tsim no tsis yog ib qho kev hloov kho xwb tab sis muaj kev sib sib zog nqus ntawm cov khoom ua tau zoo thiab cov qauv kev nyab xeeb.

Txhim khu kev ruaj ntseg: Lub ntsej muag blunt ua rau txo qis qhov kev pheej hmoo ntawm kev sib tsoo ntawm cov ntaub so ntswg uas tsis yog -piv txwv li, aortic cag, atrial dawb phab ntsa). Txawm hais tias muaj qhov sib txawv me me, qhov blunt tip tendstshem tawmes tsis yog nkag mus rau cov ntaub so ntswg, muab cov neeg ua haujlwm nrog kev nyab xeeb ntau dua.

Tshem tawm ntawm particle tiam: Lub ntsej muag ntse ntawm cov khoom siv kho tshuab ib txwm tuaj yeem tso cov khoom yas thaum nce qib hauv cov hnab yas. Cov khoom no ua rau muaj kev pheej hmoo embolism yog tias nkag mus rau hauv cov hlab ntsha. Lub blunt tip tsim tshem tawm qhov teeb meem no kiag li.

Manufacturing kev sib tw: Machining ib tug du, symmetrical blunt spherical tip nrog ib tug tshwj xeeb lub vojvoog ntawm curvature ntawm ib tug ultra- nyias stainless hlau raj nthuav tawm ib qho kev sib tw tseem ceeb. Nws yuav tsum tau ultra- siab- precision CNC tshuab cuab yeej thiab cov txheej txheem tshwj xeeb tsim / polishing kom ntseeg tau tias lub hau yog du thiab burr -dawb, nrog rau kev hloov seamless mus rau rab koob lub cev uas tsis cuam tshuam kev nce qib hauv lub plhaub.

Los ntawm Cov Khoom Siv rau Cov Khoom Siv: Cov Chaw Tsim Khoom Siv Khoom Siv Hluav Taws Xob

Cov chaw tsim khoom lub luag haujlwm yog los hloov ASTM-raws li kev kho mob stainless hlau cov ntaub ntawv raw rau hauv cov khoom kawg ntsib cov qauv tsim los ntawm cov txheej txheem precision:

Material pretreatment thiab ua hauj lwm hardening: Precisely tswj kev kos duab thiab dov txheej txheem ua tiav lub hom phiaj hardness thiab qhov ntev thaum kho cov microstructure los txhim kho lub zog.

Precision machining: Ntawm Citizen R04 cov cav tov, tubing yog fabricated rau hauv rab koob lub cev nrog meej txheej diameters, lumens, tapers, thiab tip geometries.

Kev kho cua sov thiab txo kev ntxhov siab: Kev kho cua sov ntawm cov theem tsim nyog tshem tawm cov kev ntxhov siab hauv machining, stabilizes qhov ntev, thiab optimizes cov khoom siv tag nrho cov khoom siv.

Nto xov: Electropolishing muab ib qho ultra{0}} du nto, ntxiv tshem tawm cov txheej txheem deg los ntawm machining thiab txhim kho corrosion qaug zog.

Hauv RF transseptal koob, 304/305 stainless hlau hla nws lub luag haujlwm raws li cov khoom siv, ua tiav ntau yam tseem ceeb: kev siv hluav taws xob, kev ruaj ntseg, thiab kev xa khoom zoo. Cov neeg tsim khoom siv cov txheej txheem ua haujlwm txias ua haujlwm thiab kev kho cua sov kom ua tau zoo tshaj plaws ntawm cov khoom siv classic no. Ua ke nrog ib tug ingenious blunt tip tsim, qhov tshwm sim yog ib tug phais ntsuas uas sib npaug rigidity thiab yooj, kev nyab xeeb thiab efficiency. Qhov no qhia txog qhov tseeb tseem ceeb hauv cov khoom siv kho mob siab - kawg: kev nkag siab tob thiab kev siv tshiab ntawm cov ntaub ntawv yooj yim feem ntau ua rau muaj kev cuam tshuam thev naus laus zis thiab txhim kho tus nqi kho mob.
