Yintoni iCatheter ekhokelayo? Iindidi, Ukusetyenziswa, kunye nomahluko achazwayo

Kwihlabathi lezonyango zanamhlanje, ukuchaneka, ukuthembeka, kunye nokhuseleko azinakuxoxiswana. Phakathi kwezixhobo ezininzi ezinika amandla iingcali zezempilo ukuba zinike unyango olusemgangathweni ophezulu,i-catheter ekhokelayoIbonakala njengecandelo elibalulekileyo kwiinkqubo ezingangenisi kakhulu. Njengenxalenye yoluhlu olubanzi lweii-catheters zonyango, ii-catheters ezikhokelayo zidlala indima ebalulekileyo ekuxilongeni, kunyango, nakwimisebenzi yotyando. Kwiingcali ezibandakanyeka kubonelelo lwezonyango kunyeizinto ezisetyenziswayo kwezonyangoUkuqonda usetyenziso, iintlobo, kunye nomahluko wezi zixhobo kubalulekile ekunikezeni izisombululo zezempilo ezisemgangathweni.

Yintoni iCatheter ekhokelayo?

I-catheter ekhokelayo yityhubhu eyenzelwe ngokukodwa ukukhokela ezinye izixhobo, ezinje ngee-stents, iibhaluni, okanye ii-guidewire, kwindawo ethile emzimbeni—ngokuqhelekileyo ngaphakathi kwenkqubo yemithambo yegazi. Ezi catheter zibonelela ngenkxaso kunye nozinzo, zivumela ulawulo oluchanekileyo ngexesha leenkqubo ezifana ne-coronary angiography okanye i-percutaneous coronary intervention (PCI).

Ngokungafaniyo nee-catheter zokuxilonga, ii-catheter ezikhokelayo zikhulu ngobubanzi kwaye ziqinile ngakumbi, nto leyo evumela ukuba zithumele ezinye izixhobo ngelixa zigcina indawo yazo ngaphakathi kwemithambo yegazi. Zihlala zifakwa nge-peripheral artery (njenge-femoral okanye i-radial artery) kwaye zihanjiswa ngenkqubo yemithambo yegazi ukuze zifikelele entliziyweni okanye kwezinye iindawo ekujoliswe kuzo.

Iintlobo zeeCatheters ezikhokelayo

Kukho iintlobo ngeentlobo zee-catheter ezikhokelayo ezikhoyo, nganye yenzelwe ukuhlangabezana neemfuno ezithile zeklinikhi kunye nokwahluka komzimba. Ukukhetha uhlobo lwe-catheter kuxhomekeke kwinkqubo, imeko yesigulana, kunye nokukhetha kukagqirha. Ezinye iintlobo eziqhelekileyo ziquka:

I-Judkins Ekhohlo (JL) kunye ne-Judkins Ekunene (JR): Ezi zisetyenziswa kakhulu kwiindlela zokungenelela kwentliziyo. I-JL yenzelwe umthambo wentliziyo wasekhohlo, ngelixa i-JR isetyenziselwa ekunene.
I-Amplatz (AL/AR): Yenzelwe ukufikelela kwimithambo yegazi enzima okanye engaqhelekanga, ingakumbi xa ii-catheter eziqhelekileyo zingenako ukubonelela ngenkxaso eyaneleyo.
Iinjongo ezininzi (MP): Inika ukuguquguquka kokufikelela kwiindawo ezininzi zemithambo yegazi.
I-Extra Backup (XB okanye i-EBU): Inika inkxaso ephuculweyo kunye nozinzo kwiimeko ezinzima okanye kwi-anatomy ebuhlungu.

Uhlobo ngalunye luyahluka ngokwemilo yencam, ubude, kunye nokuguquguquka, nto leyo eyenza ukhetho olufanelekileyo lube lolona lubalulekileyo kwimpumelelo yenkqubo.

Ukusetyenziswa kweeCatheters ezikhokelayo kwizonyango

Ii-catheter ezikhokelayo zisetyenziswa kakhulu kwiinkqubo zentliziyo, i-neurology, kunye ne-radiology yokungenelela. Nazi ezinye zeendlela ezisetyenziswa ngazo:

Ukungenelela kweCoronary: Ukwenza kube lula ukufakwa kwee-stents okanye iibhaluni kwimithambo evalekileyo ngexesha le-angioplasty.
Iinkqubo ze-Electrophysiology: Ukufaka izixhobo zokumapha kunye nezokukhupha entliziyweni.
Iinkqubo zeNeurovascular: Ukuhambisa ii-coils okanye ii-embolic agents ekunyangeni ii-aneurysms okanye ii-arteriovenous malformations.
Ukungenelela Kwangaphandle: Kusetyenziselwa ukufikelela kwimithambo yegazi engaphandle kunye nokuhambisa unyango kwimithambo yegazi evalekileyo okanye exineneyo.

Ngenxa yokuguquguquka kwazo kunye nendima yazo ebalulekileyo ekuhambiseni ezinye izixhobo, ii-catheters ezikhokelayo zibalulekile kwimpahla yazo naziphi na iziko lezonyango okanye umthengisi wezinto ezisetyenziswayo zonyango.

Umahluko phakathi kweGuidewire kunye neCatheter

Nangona isetyenziswa rhoqo kunye,iingcingo zesikhokelokwaye ii-catheters zisebenza ngeenjongo ezahlukeneyo kwiinkqubo zonyango.

Intambo yoMqondisi: Intambo ebhityileyo neguquguqukayo esetyenziselwa ukuhamba kwinkqubo yemithambo yegazi ukuze ifikelele kwindawo ethile ekujoliswe kuyo. Isebenza “njengendlela yokufumana indlela” kwii-catheters nakwezinye izixhobo.
I-Catheter: Ityhubhu engenanto ebekwe phezu kwentambo yokubonisa ukuze ihambise izixhobo zonyango okanye zokuxilonga kwindawo yonyango.

Ngamafutshane, ucingo olukhokelayo lukhokela indlela, kwaye i-catheter ilandela. Nangona ucingo olukhokelayo lubonelela ngobuchule bokuhamba, i-catheter ibonelela ngesakhiwo kunye nomjelo wezixhobo ezongezelelweyo.

Ukukhokela iiCatheters kwiCandelo lokuNikezela ngezoNyango

Ngenxa yokwanda kwezifo zentliziyo kunye notshintsho lwehlabathi oluya kwiinkqubo ezingangenisi mandla kangako, imfuno yee-catheters ezikhokelayo ikhule kakhulu. Abathengisi kunye nabavelisi bezixhobo zonyango kufuneka baqinisekise ukuba ezi zixhobo ziyahlangabezana nemigangatho yomgangatho wamazwe ngamazwe efana nesatifikethi se-ISO kunye ne-CE.

Izinto ezinje ngokubulala iintsholongwane, ukuqina kwezinto, ukuhambelana kwezinto eziphilayo, kunye nokupakishwa zizinto ezibalulekileyo ekufuneka ziqwalaselwe xa kuthunyelwa kwamanye amazwe.ii-catheters zonyangoIinkampani ezibandakanyeka kwihlabathi liphelaizinto ezisetyenziswayo kwezonyangourhwebo kufuneka luqaphele iimfuno zomthetho kwiimarike ekujoliswe kuzo ezifana ne-EU, i-US, kunye ne-Middle East.

Isiphelo

I-catheter ekhokelayo ayisiyonto nje yokuhambisa amanzi—sisixhobo esibalulekileyo esivumela iinkqubo zokusindisa ubomi. Njengoko iinkqubo zokhathalelo lwempilo kwihlabathi liphela ziqhubeka nokusebenzisa iindlela zonyango eziphucukileyo nezingenazo izithintelo, ii-catheter ezikhokelayo ziya kuhlala zizixhobo ezibalulekileyo koogqirha. Kwabo bachaphazelekayo kushishino lokubonelela ngezonyango kunye nezinto ezisetyenziswayo zonyango, ukuqonda nokukhuthaza ixabiso lezi zixhobo kubalulekile ekuqhubeni ubuchule kunye nokuphucula ukhathalelo lwezigulane.
