Munyika yemishonga yemazuva ano, kunyatsoita, kuvimbika, uye kuchengeteka hazvigoni kurongeka. Pakati pezvishandiso zvakawanda zvinopa simba vashandi vehutano kuti vape kutarisirwa kwemhando yepamusoro, iyokutungamira catheterinomira pachena sechikamu chakakosha mune zvishoma invasive maitiro. Sechikamu chechikamu chakafara chezvekurapa catheters, makateta anotungamira anoita basa rakakosha mukuongorora, kurapwa, uye kupindira kwekuvhiya. Kune nyanzvi mune zvekurapa uyemishonga inodyiwa, kunzwisisa mashandisirwo, mhando, uye misiyano yezvishandiso izvi kiyi yekuunza mhinduro dzehutano hwehutano.
Chii chinonzi Guiding Catheter?
Catheter inotungamira ichubhu yakanyatsogadzirwa inoshandiswa kutungamira zvimwe zviridzwa, senge stents, mabharumu, kana maguidewaya, munzvimbo chaiyo mukati memuviri-kazhinji mukati mevascular system. Aya makateta anopa rutsigiro uye kugadzikana, achibvumira kunyatso kudzora panguva yemaitiro senge coronary angiography kana percutaneous coronary intervention (PCI).
Kusiyana nekuongorora catheter, kutungamira catheter yakakura muhupamhi uye yakasimba, iyo inovabvumira kuendesa mamwe maturusi vachichengetedza nzvimbo yavo mukati memudziyo. Iwo anowanzo kuisirwa kuburikidza neperipheral artery (yakadai seyechikadzi kana radial artery) uye inofambiswa nepakati pevascular system kusvika pamoyo kana dzimwe nzvimbo dzakanangwa.
Mhando dzeKutungamirira Catheters
Kune marudzi akasiyana-siyana ekutungamira catheter anowanikwa, imwe neimwe yakagadzirirwa kusangana nezvinodiwa zvekiriniki uye kusiyanisa kweanatomical. Kusarudzwa kwemhando yecatheter kunoenderana nemaitiro, mamiriro emurwere, uye zvinodiwa nachiremba. Mamwe marudzi akajairika anosanganisira:
Judkins Kuruboshwe (JL) uye Judkins Kurudyi (JR): Izvi zvinowanzoshandiswa mukupindira kwemwoyo. JL yakagadzirirwa kuruboshwe coronary artery, nepo JR inoshandiswa kurudyi.
Amplatz (AL/AR): Yakagadzirirwa zvakanyanya kuomarara kana atypical vascular kuwana, kunyanya kana macatheter akajairwa asingakwanisi kupa rubatsiro rwakakwana.
Multipurpose (MP): Inopa kuchinjika kwekuwana akawanda vascular territories.
Yekuwedzera Backup (XB kana EBU): Inopa yakawedzera rutsigiro uye kugadzikana kune dzakaoma nyaya kana tortuous anatomy.
Rudzi rwega rwega rwunosiyana maererano nechimiro chetipi, kureba, uye kuchinjika, zvichiita kuti sarudzo chaiyo yakakosha pakubudirira kwemaitiro.
Kushandiswa kweKutungamira Catheter muKurapa Kudzidzira
Inotungamira catheter inoshandiswa zvakanyanya muhutano hwemwoyo, neurology, uye interventional radiology. Heano mamwe ekutanga maapplication avo:
Kupindira kweCoronary: Kufambisa kuiswa kwemastents kana mabharumu mutsinga dzakavharika panguva yeangioplasty.
Electrophysiology Procedures: Yekuunza mepu uye maturusi ekubvisa mukati memoyo.
Neurovascular Procedures: Yekuendesa macoil kana embolic agents mukurapa aneurysms kana arteriovenous malformations.
Peripheral Interventions: Inoshandiswa kuwana peripheral arteries uye kuendesa kurapwa kune yakavharika kana yakamanikana midziyo.
Nekuda kwekuita kwavo kwakasiyana-siyana uye basa rakakosha mukuendesa zvimwe zviridzwa, kutungamira catheter chinhu chikuru muzvinyorwa zvechero nzvimbo yekurapa kana mutengesi wezvokurapa.
Musiyano Pakati peGuidewire neCatheter
Kunyange zvazvo kazhinji inoshandiswa pamwe chete,guidewiresuye catheter inoshandisa zvinangwa zvakasiyana mukurapa maitiro.
Guidewire: Waya yakatetepa, inochinjika inoshandiswa kufamba nepakati pevascular system kuti isvike pachinangwa chaicho. Inoshanda se "pathfinder" ye catheters uye mamwe madivayiri.
Catheter: Iyo hollow chubhu inokwidziridzwa pamusoro pegidhiwire kuendesa ekurapa kana yekuongorora maturusi kunzvimbo yekurapa.
Muchidimbu, gwara rinotungamira nzira, uye catheter inotevera. Nepo iyo guidewire ichipa maneuverability, iyo catheter inopa chimiro uye mugero wemamwe maturusi.
Kutungamira Catheters muMedical Supply Chain
Nekukwira kwezvirwere zvemoyo uye shanduko yepasirese kuenda kune zvishoma zvinopinda maitiro, kudiwa kweinotungamira catheter kwakura zvakanyanya. Vatengesi kunze nevagadziri vezvekushandisa pakurapa vanofanirwa kuve nechokwadi chekuti michina iyi inosangana nemhando dzepasi rose senge ISO uye CE certification.
Zvinhu zvakadai sekuita sterilization, kusimba kwezvinhu, biocompatibility, uye kurongedza ndizvo zvakakosha kufunga mukutengesa kunze kwenyikazvekurapa catheters. Makambani akabatanidzwa munyikamishonga inodyiwakutengeserana kunofanirwawo kuziva nezvezvinodiwa zvekutonga mumisika inotarwa seEU, US, uye Middle East.
Mhedziso
Iyo catheter inotungamira inopfuura kungoita chidimbu chechubhu - chishandiso chakakosha chinogonesa nzira dzekuponesa hupenyu. Sezvo masisitimu ehutano pasirese arikuramba achitora nzira dzepamberi, dzisinganyanyi kurapa, ma catheter anotungamira acharamba ari maturusi akakosha kuvarapi. Kune vanobatana muindasitiri yezvekurapa uye zvinodyiwa zvekurapa, kunzwisisa uye kusimudzira kukosha kwezvishandiso izvi kwakakosha pakufambisa hunyanzvi uye kuvandudza kutarisirwa kwevarwere.
