Emkhakheni wemithi yesimanje, ikakhulukazi ngaphakathii-cardiology yokungenelela, i-radiology, futhiukuhlinzwa kwemithambo, amathuluzi ambalwa abaluleke kakhulu njenge-isethulo emgodleni. Njengesisekeloidivayisi yezokwelapha, i-introducer sheath yenza ukufinyelela kwe-vascular okuphephile nokusebenza kahle, okuvumela odokotela ukuba benze izinqubo zokuxilonga nezokwelapha ngokunemba nokulawula.
Lo mhlahlandlela ophelele uzochaza ukuthi uyini umgodla wesingeniso, kanjaniubuchwepheshe be-sheath steerableithuthukisa imiphumela yenqubo, nokuthi imigodla yesingeniso ihluke kanjani kwezinye ezifanayoimikhiqizo yezokwelaphanjengama-catheter aqondisayo. Sizophinde sihlole izizathu ezibalulekile zokuthi kungani ama-sheaths esethulo esetshenziswa kabanzi kuizinqubo ze-angiographic.
Iyini I-Introducer Sheath?
An isethulo emgodleniiyisipesheliidivayisi yezokwelaphayakhelwe ukusiza ukufinyelela emithanjeni yegazi ngesikhathi sezinqubo ezihlasela kancane. Ivamise ukufakwa emthanjeni osemngceleni noma emthanjeni—ikakhulukazi umthambo wesifazane noma we-radial—ukwenza umgudu wokufakwa kwama-catheter, izintambo, amabhaluni, namanye amathuluzi asetshenziswa ezinqubweni zokuxilonga nezokungenela.
Umgodla wesingeniso uqukethe ishubhu eligobekayo, elingenalutho elinevalvu ene-hemostatic kanye ne-dilator. I-dilator isiza ukufaka i-sheath emkhunjini, futhi i-valve igcinai-hemostasis, ukuvimbela ukulahleka kwegazi lapho izinto zokusebenza zifakwa noma zikhishwa.
Imisebenzi Ebalulekile Ye-Introducer Sheath:
- Inikeza indawo yokufinyelela ezinzile ohlelweni lwemithambo yegazi.
- Ivikela umkhumbi ekulimaleni okubangelwa ukufakwa okuphindaphindiwe kwamadivayisi.
- Igcina uhlelo oluvaliwe lokunciphisa ingozi yokopha kanye nokutheleleka.
- Ivumela ukushintshaniswa kwedivayisi okusheshayo nokuphumelelayo.
Amashethi ezethulo atholakala ngobukhulu obuhlukahlukene, ubude, kanye nezinto ezisetshenziswayo ukuze kuhlangatshezwane nezinqubo ezihlukene kanye nama-anatomi esiguli.
I-Steerable Sheath Technology
Ekungeneleleni okuyinkimbinkimbi kwenhliziyo nemithambo yegazi noma ku-neurovascular, amashethi endabuko aqondile angakhawulela ukufinyelela kuma-anatomi ayinselele. Lo mkhawulo uholele ekuthuthukisweni kweimigodla yesingeniso esiqondisayo-indlela entsha ethuthukisa kakhulu ukuguquguquka nokunemba kwenqubo.
A umgodla oqondisayoifaka ithiphu eliguquguqukayo noma elishoyo, elingazulazula eziqondisweni eziningi kusetshenziswa isibambo noma ukudayela ekugcineni kwe-proximal. Lokhu kuchaza kuvumela ukumisa okunembile kwamadivayisi ngaphakathi kwezindawo ezihlukumezayo noma okunzima ukufinyelela kuzo zohlelo lwemithambo yegazi.
Izinzuzo zama-Steerable Introducer Sheaths:
- Ukuzulazula okuthuthukisiwengokusebenzisa izindlela ezinzima ze-vascular.
- Ukulawulwa kwenqubo okuthuthukisiwe, ikakhulukazi ezindaweni ezivaliwe ze-anatomical.
- Ukuhlukumezeka okuncishisiweezindongeni zomkhumbi ngokunciphisa ukukhwabanisa ngokweqile.
- Ukwesekwa okuphelelekumasistimu okulethwa kwedivayisi.
Amashethi alawulekayo anenzuzo ikakhulukazi ezinqubweni zesakhiwo senhliziyo (isb., ukuvaleka kwe-appendage ye-atrial yesokunxele, ukulungiswa kwevalvu ye-mitral), izifundo ze-electrophysiology, nokungenelela kwe-neurovascular njenge-aneurysm coiling noma i-thrombectomy.
I-Guiding Catheter vs. I-Sheath Yesethulo: Uyini Umehluko?
Nakubaama-catheter aqondisayofuthiizigqoko zokwethulawomabili amathuluzi asetshenziselwa ukuthola ukufinyelela kwemithambo futhi alethe amadivaysi okungenelela, asebenza ngezinhloso ezahlukene futhi akhiwe ngendlela ehlukile.
| Isici | I-Catheter Eqondisayo | Umethuli we-Sheath |
| Ukusetshenziswa Okuyinhloko | Qondisa futhi usekele amadivaysi okuxilonga noma okwelapha kusayithi eliqondiwe | Dala futhi ugcine ukufinyelela kwemithambo |
| Idizayini | Okude, okumise okwengaphambili ngesilawuli se-torque | Okufushane, okuvumelana nezimo nokuhleleka kokuzikhethela |
| I-Valve System | Ngokuvamile ayinayo i-valve ye-hemostasis | Ifakwe i-hemostatic valve ukunciphisa ukulahleka kwegazi |
| Ukubekwa | Ifakwe ekujuleni kwesistimu ye-vascular | Imiswe endaweni yokungena (isb., umthambo wesifazane noma we-radial) |
| Ukusekela | Inikeza isiqondiso esiqondisayo nokusekelwa kwamasistimu e-catheter | Isebenza njengengosi yesingeniso nokushintshisana kwedivayisi |
Uukuqonda umehluko kubalulekile lapho ukhetha okufaneleimikhiqizo yezokwelaphangenqubo enikeziwe.
Kungani I-Introducer Sheaths Isetshenziselwa Izinqubo ze-Angiographic?
Amashethi e-Introducer asetshenziswa kakhulu kuizinqubo ze-angiographicngoba benza lula inqubo yokujova udayi ohlukile, ukuthola izithombe, nokusebenzisa amathuluzi okungenelela-konke ngenkathi kugcinwa ubuqotho bemithambo.
Izinzuzo Eziyinhloko Zesethulo Semigoqo ku-Angiography:
- Londoloza Ukufinyelela Umkhumbi
Uma usufakiwe, i-sheath igcina indawo yokufinyelela ezinzile futhi evulekile. Lokhu kuvimbela ukubhoboza okuphindaphindiwe futhi kunciphisa ingozi yezinkinga. - Nika amandla Ukuhwebelana Kwamadivayisi Amaningi
Izinqubo ze-angiographic eziyinkimbinkimbi ngokuvamile zidinga ukusetshenziswa kwama-catheter amaningana ahlukene nezintambo. Ishethi yesethulo ivumela lawa madivayisi ukuthi ashintshwe ngokushesha nangokuphepha ngendawo eyodwa yokufinyelela. - Gcina I-Hemostasis
Ngenxa ye-valve eyakhelwe ngaphakathi, i-sheath ivimbela igazi ukuthi lingaphumi ngisho nalapho amathuluzi edlula kuwo. Lokhu kunciphisa ukulahleka kwegazi futhi kugcina ukuzinza kwesiguli. - Yehlisa Ingozi Yezinkinga
Ngokunciphisa ukuhlukumezeka komkhumbi nokugcina indlela eyinyumba yamadivayisi, ama-sheaths e-introducer anciphisa ingozi yokuhlukaniswa komkhumbi, i-thrombosis, noma ukutheleleka. - Thuthukisa Isikhathi Senqubo Nokusebenza Kahle
Ngokufinyelela okulula nokushintshana kwedivayisi okusheshayo, amashethi esethuli asiza ukwehlisa isikhathi senqubo—okubalulekile kukho kokubili ukungenelela okukhethekile nokuphuthumayo.
Lezi zinzuzo zichaza ukuthi kungani amashethi esethuli angamathuluzi ajwayelekile ezinkambisweni ezifana ne-coronary angiography, i-peripheral angioplasty, kanye ne-cerebral embolization.
Isiphetho
Iisethulo emgodleniiyitshe legumbiidivayisi yezokwelaphaendaweni yanamuhla yokungenelela. Iqhaza layo ekusizeni ukufinyelela okuphephile, okuphindaphindwayo kwemithambo akukwazi ukweqiwa. Njengoba izinqubo zezokwelapha ziba nzima kakhulu, izinto ezintsha ezifana neumgodla wesingeniso esiqondisayobahlela kabusha indlela odokotela ababhekana ngayo nezinselele ze-anatomies futhi bahlele ukuhamba komsebenzi.
Ukuqonda umsebenzi kanye nezinzuzo zamashethi ezethulo-kanye nokuthi ziqhathaniswa kanjani nezinyeimikhiqizo yezokwelaphanjengama-catheter aqondisayo-kunikeza ochwepheshe bezokunakekelwa kwempilo amandla ukuthi benze izinqumo ezinolwazi ezithuthukisa imiphumela yesiguli kanye nempumelelo yenqubo.
Noma ngabe ungudokotela, umqondisi wokunakekelwa kwezempilo, noma umsabalalisi womkhiqizo, uhambisana nokwakamuvaumgodla oqondisayoubuchwepheshe kanye namathuluzi okufinyelela emithanjeni kubalulekile ukuze kugcinwe ukusebenza kahle ekunakekelweni kwesiguli.
