Kwinkalo yamayeza anamhlanje, ngakumbi ngaphakathii-cardiology yongenelelo, i-radiology, kwayeutyando lwemithambo, izixhobo ezimbalwa ziyimfuneko njengeisingxobo sokwazisa. Njengesisekoisixhobo sonyango, i-introducer sheath yenza ukuba i-vascular access ikhuselekile kwaye isebenze kakuhle, ivumela oogqirha ukuba benze iinkqubo zokuxilonga kunye zonyango ngokuchanekileyo kunye nokulawula.
Esi sikhokelo sibanzi siya kuchaza ukuba yintoni isheath ye-introducer, njaniitekhnoloji ye-sheath esebenzayoiphucula iziphumo zenkqubo, kunye nendlela iishethi zokwazisa zahluke njani kwezinye ezifanayoiimveliso zonyangonjengeecatheter ezikhokelayo. Siza kuphinda sihlolisise izizathu ezibalulekileyo zokuba kutheni ii-sheaths zokwazisa zisetyenziswa ngokubanziiinkqubo angiographic.
Yintoni I-Introducer Sheath?
An isingxobo sokwazisayinto ekhethekileyoisixhobo sonyangoeyenzelwe ukuququzelela ukufikelela kwimithambo yegazi ngexesha leenkqubo zokuhlasela kancinci. Ngokuqhelekileyo ifakwe kwi-peripheral artery okanye i-vein-ngokuqhelekileyo i-femoral okanye i-radial artery-ukudala i-conduit yokufakwa kwee-catheters, iingcingo, iibhaluni, kunye nezinye izixhobo ezisetyenziselwa ukuxilonga kunye neenkqubo zokungenelela.
I-sheath ye-introducer ine-flexible, ityhubhu engenanto kunye ne-valve ye-hemostatic kunye ne-dilator. I-dilator inceda ukufaka i-sheath kwisitya, kwaye i-valve igcinaukopha, ukuthintela ukulahleka kwegazi xa izixhobo zifakwe okanye zisusiwe.
Imisebenzi engundoqo ye-Introducer Sheath:
- Inika indawo yokufikelela ezinzileyo kwi-vascular system.
- Ikhusela umkhumbi kwintlungu ebangelwa ukufakwa ngokuphindaphindiweyo kwezixhobo.
- Ugcina inkqubo evaliweyo yokunciphisa umngcipheko wokopha kunye nosulelo.
- Ivumela utshintshiselwano olukhawulezayo nolusebenzayo lwesixhobo.
Iishethi zokwazisa ziyafumaneka ngobukhulu obahlukeneyo, ubude, kunye nezixhobo ukulungiselela iinkqubo ezahlukeneyo kunye ne-anatomies yesigulana.
Itekhnoloji yeSteerable Sheath
Kungenelelo oluntsonkothileyo lwe-cardiovascular or neurovascular, sheaths zemveli ezithe tye zinokunciphisa ukufikelela kumngeni we-anatomies. Lo mda kukhokelele kuphuhliso lweizingxobo zentshayelelo ezilawulekayo-inguqulelo entsha ephucula kakhulu ukuguquguquka kwenkqubo kunye nokuchaneka.
A isingxobo esilawulekayoIbonisa incam eguquguqukayo okanye echazayo, enokuthi ihlawulwe kwiindlela ezininzi usebenzisa isiphatho okanye ukucofa kwisiphelo esisondele. Le nkcazo ivumela ukubeka ngokuchanekileyo kwezixhobo kwiindawo ezibuhlungu okanye ezinzima ukufikelela kwi-vascular system.
Izinto eziluncedo kwi-Steerable Introducer Sheaths:
- Ukuphuculwa kokukhangelangeendlela ezinzima ze-vascular.
- Ulawulo lwenkqubo olwandisiweyo, ngakumbi kwiindawo ezivaliweyo ze-anatomical.
- Umothuko ophantsikwiindonga zenqanawa ngokunciphisa ukuguqulwa okugqithisileyo.
- Inkxaso efanelekileyokwiinkqubo zonikezelo lwesixhobo.
Iisheaths ezikwaziyo ukulawuleka ziluncedo kakhulu kwiinkqubo zentliziyo (umzekelo, ukuvala i-atrial appendage ekhohlo, ukulungiswa kwevalve ye-mitral), izifundo ze-electrophysiology, kunye nongenelelo lwe-neurovascular olufana ne-aneurysm coiling okanye i-thrombectomy.
I-Catheter eKhokelayo vs. Intshayelelo ye-Sheath: Yintoni uMahluko?
Nangonaii-catheters ezikhokelayokwayeizingxobo zokwazisazombini izixhobo ezisetyenziselwa ukufumana ukufikelela kwi-vascular kunye nokuhambisa izixhobo zokungenelela, zikhonza iinjongo ezahlukeneyo kwaye zakhiwe ngokwahlukileyo.
| Uphawu | I-Catheter ekhokelayo | Intshayelelo Sheath |
| Ukusetyenziswa okuPhambili | Isikhokelo kunye nenkxaso yoxilongo okanye izixhobo zonyango kwindawo ekujoliswe kuyo | Yenza kwaye ugcine ukufikelela kwi-vascular |
| Yila | Ixesha elide, i-pre-shaped kunye nolawulo lwe-torque | Mfutshane, bhetyebhetye kunye ne-optional steerability |
| Inkqubo yeValve | Ngokuqhelekileyo ayinayo ivalve ye-hemostasis | Ixhotyiswe ngevalve ye-hemostatic ukunciphisa ukulahleka kwegazi |
| Ukubekwa | Ifakwe nzulu kwi-vascular system | Ibekwe kwindawo yokungena (umzekelo, i-femoral okanye i-radial artery) |
| Inkxaso | Inika isikhokelo esisikhokelo kunye nenkxaso yeenkqubo zecatheter | Isebenza njengesango lokwazisa isixhobo kunye notshintshiselwano |
Uukuqonda umahluko kubalulekile xa ukhetha ofanelekileyoiimveliso zonyangongenkqubo enikiweyo.
Kutheni i-Introducer Sheaths isetyenziselwa kwiiNkqubo ze-Angiographic?
Iintroduce sheaths ziqhele ukusetyenziswa kwiiinkqubo angiographicngenxa yokuba balungelelanisa inkqubo yokujova idayi echaseneyo, ukufumana umfanekiso, kunye nokuhambisa izixhobo zokungenelela-konke ngelixa kugcinwa ukunyaniseka kwe-vascular.
Izinto eziNzuzo eziphambili zeNtshayelelo ye-Sheaths kwi-Angiography:
- Londoloza ukufikelela kwiSikhephe
Xa sele ifakiwe, i-sheath igcina indawo yokufikelela ezinzileyo kunye nevulekileyo. Oku kuthintela i-punctures ngokuphindaphindiweyo kwaye kunciphisa umngcipheko weengxaki. - Yenza uTshintshiselwano lweZixhobo ezininzi
Iinkqubo ezintsonkothileyo ze-angiographic zihlala zifuna ukusetyenziswa kweecatheter ezahlukeneyo kunye neengcingo. I-introducer sheath ivumela ezi zixhobo ukuba zitshintshwe ngokukhawuleza nangokukhuselekileyo ngendawo yokufikelela enye. - Gcina i-Hemostasis
Ngombulelo kwivalvu eyakhelwe-ngaphakathi, i-sheath ithintela igazi ukuba lingaphumi njengoko izixhobo zidlula kuyo. Oku kunciphisa ukulahleka kwegazi kunye nokugcina uzinzo lwesigulane. - Nciphisa umngcipheko weengxaki
Ngokunciphisa ukwenzakala kwenqanawa kunye nokugcina indlela eyinyumba yezixhobo, iisheaths ze-introducer zinciphisa umngcipheko wokuqhekeka kwenqanawa, i-thrombosis, okanye usulelo. - Ukuphucula ixesha leNkqubo kunye nokusebenza kakuhle
Ngokufikelela ngokulula kunye nokutshintshiselana ngokukhawuleza kwesixhobo, iishethi zokwazisa zinceda ukunciphisa ixesha lenkqubo-ebaluleke kakhulu kungenelelo olukhethiweyo kunye nongxamiseko.
Ezi zibonelelo zichaza ukuba kutheni i-introducer sheaths zizixhobo eziqhelekileyo kwiinkqubo ezifana ne-coronary angiography, i-peripheral angioplasty, kunye ne-cerebral embolization.
Ukuqukumbela
Iisingxobo sokwazisalilitye lembomboisixhobo sonyangokumhlaba wanamhlanje wongenelelo. Indima yayo ekuququzeleleni ukukhuseleka, ukuphindaphinda ukufikelela kwi-vascular ayikwazi ukugqithiswa. Njengoko iinkqubo zonyango ziba nzima ngakumbi, izinto ezintsha ezifana neisingxobo sokwazisabalungisa ngokutsha indlela abezonyango abajongana ngayo nocelomngeni lwe-anatomi kunye nokuhamba kakuhle komsebenzi.
Ukuqonda umsebenzi kunye neenzuzo ze-introducer sheaths-kunye nendlela ezithelekisa ngayo nezinyeiimveliso zonyangonjenge-catheters ekhokelayo-ixhobisa abaqeqeshi bezempilo ukuba benze izigqibo ezinolwazi eziphucula iziphumo zesigulane kunye nempumelelo yenkqubo.
Nokuba ungugqirha, umlawuli wezempilo, okanye uhambisa imveliso, uhlala unolwazi lwamva njeisingxobo esilawulekayoiteknoloji kunye nezixhobo zokufikelela kwi-vascular zibalulekile ekugcineni ukugqwesa kwinkathalo yesigulane.
