Amayunithi e-Electrosurgical(ESU) iyithuluzi lokuhlinza ngogesi elisebenzisa amandla kagesi wemvamisa ephezulu ukusika izicubu nokulawula ukopha ngokubangela ukuhlangana.Ishisa izicubu lapho i-high-frequency high-voltage current ekhiqizwe ithiphu ye-electrode esebenzayo ixhumene nomzimba, futhi ibona ukuhlukana nokuhlangana kwezicubu zomzimba, ngaleyo ndlela kufezeke inhloso yokusika kanye ne-hemostasis.
I-ESU ingase isebenzise imodi ye-monopolar noma i-bipolar
1.Imodi ye-Monopolar
Kumodi ye-monopolar, isifunda esiphelele sisetshenziselwa ukusika nokuqinisa izicubu.Isekethe iqukethe i-high-frequency generator, ipuleti elingalungile,Isixhumi sekhebula lephedi eliphansikanye nama-electrode.Umthelela wokushisa wamayunithi we-electrosurgical high-frequency ungabhubhisa izicubu ezigulayo.Iqoqa i-high-density kanye ne-high-frequency current futhi ibhubhisa izicubu endaweni lapho ithinta khona ichopho le-electrode ephumelelayo.Ukuqina kwenzeka lapho izinga lokushisa lethishu noma iseli elixhumene ne-electrode likhuphuka lifinyelela ekushintsheni kwephrotheni kuseli.Lo mphumela wokuhlinzwa onembile uncike ku-waveform, i-voltage, yamanje, uhlobo lwethishu, kanye nokuma nosayizi we-electrode.
2.Imodi ye-Bipolar
Ububanzi besenzo bukhawulelwe emikhawulweni emibili ye-i-bipolar forceps, futhi umonakalo kanye nobubanzi bethonya lama-forceps kuncane kakhulu kune-monopolar.Ilungele ukuvimba imithambo yegazi emincane (ububanzi obungaphansi kwe-4 mm) namashubhu e-fallopian.Ngakho-ke, i-bipolar coagulation isetshenziswa kakhulu ekuhlinzweni kobuchopho, i-microsurgery, izici ezinhlanu, i-obstetrics kanye ne-gynecology, ukuhlinzwa kwesandla, njll. Ukuphepha kwamayunithi we-electrosurgical high-frequency units bipolar coagulation kuqashelwa kancane kancane, futhi ububanzi bokusebenza bayo buyanda kancane kancane.
Umgomo wokusebenza wamayunithi we-Electrosurgical
Ekuhlinzweni kwe-electrosurgical, ukugeleza kwamanje kusuka ku-Ipensela ye-electrosurgicalemzimbeni womuntu, futhi kugeleza ku-negative plate.Imvamisa imvamisa yethu yama-mains ngu-50Hz.Singakwazi futhi ukwenza i-electrosurgery kuleli bhendi yefrikhwensi, kodwa yamanje ingase ibangele ukukhuthazeka okukhulu emzimbeni womuntu futhi kubangele ukufa.Ngemuva kokuthi imvamisa yamanje idlule ku-100KHz, imizwa nemisipha ayisabeli kumanje.Ngakho-ke, amayunithi e-electrosurgical anemvamisa ephezulu aguqula i-50Hz yamanje yamapayipi amakhulu ibe imvamisa ephezulu engaphezu kuka-200KHz.Ngale ndlela, amandla e-high-frequency anganikeza ukugqugquzela okuncane esigulini.Ayikho ingozi yokushaqeka kukagesi emzimbeni womuntu.Phakathi kwazo, indima yepuleti engalungile ingenza i-loop yamanje, futhi ngesikhathi esifanayo inciphise ukuminyana kwamanje epuleti le-electrode, ukuvimbela okwamanje ukuthi ingashiyi isiguli futhi ibuyele kumayunithi we-electrosurgical high-frequency ukuze uqhubeke nokushisa. izicubu bese ushisa isiguli.
Ngokubheka umgomo wokusebenza wamayunithi wokuhlinzwa we-electrosurgical ephezulu, sidinga ukunaka izici zokuphepha ezilandelayo ngesikhathi sokusetshenziswa:
l Ukusetshenziswa okuphephile kwepuleti elibi
Amayunithi amanje e-high-frequency electrosurgical units afakwe ubuchwepheshe bokuhlukanisa imvamisa ephezulu, kanti i-high-frequency current ehlukanisiwe isebenzisa kuphelaipuleti negativenjengesiteshi kuphela sokubuyela kusekethi yamayunithi e-electrosurgical high-frequency.Nakuba uhlelo lwesifunda olungalodwa lungavikela isiguli ekushiseni kwesinye isifunda, alukwazi ukugwema ukushiswa okubangelwa izinkinga ngokuxhunywa kwepuleti elibi.Uma indawo yokuxhumana phakathi kwepuleti engalungile nesiguli ingenkulu ngokwanele, okwamanje izogxila endaweni encane, futhi izinga lokushisa lepuleti elibi lizokhuphuka, elingabangela ukushisa esigulini.Izibalo zibonisa ukuthi u-70% wezingozi ezishisiwe ze-electrosurgical units ezibikiwe zibangelwa ukwehluleka kwepuleti le-electrode elingalungile noma ukuguga.Ukuze ugweme ukushiswa kwepuleti elibi esigulini, kufanele siqinisekise indawo yokuxhumana yepuleti elibi kanye nesiguli kanye nokusebenza kwayo, futhi sikhumbule ukugwema ukusetshenziswa okuphindaphindiwe kwealahlwayo negative plate.
l Indawo yokufaka efanelekile
Zama ukuba seduze ngangokunokwenzeka endaweni yokuhlinza (kodwa kungabi ngaphansi kuka-15cm) nendawo yemisipha eyisicaba enemithambo yegazi;
Susa izinwele esikhumbeni sendawo futhi uzigcine zihlanzekile futhi zomile;
Ungaweli indawo yokusebenza kwesokunxele nakwesokudla, futhi ube kude ne-electrode ye-ECG engaphezu kuka-15cm;
Akufanele kube khona izimila zensimbi, ama-pacemaker, noma ama-electrode e-ECG ku-loop;
Uhlangothi olude lwepuleti luseduze nesiqondiso se-high-frequency current.
l Naka lapho ufaka ipuleti eliphikisayo
Ipuleti nesikhumba kufanele kuxhunywe ngokuqinile;
Gcina i-polar plate flat futhi ingasikwa noma igoqe;
Gwema ukucwilisa amapuleti e-polar ngesikhathi sokukhipha amagciwane nokugeza;
Izingane ezingaphansi kuka-15Kg kufanele zikhethe amapuleti ezinsana.
l Ezinye izindaba ezidinga ukunakwa
Hlola ukuthi izintambo zikagesi neze-electrode ziphukile futhi izintambo zensimbi zivezwe;
Xhuma i-Ipensela ye-Electrosurgicalemshinini, qala ukuzihlola, futhi ulungise amandla okukhipha ngemva kokubonisa ukuthi ipuleti elingalungile lifakwe ngendlela efanele futhi akukho sibonakaliso se-alamu;
Gwema ukusha kwe-bypass: izitho zesiguli zisongwe ngendwangu futhi zilungiswe kahle ukuze kugwenywe ukuthintana kwesikhumba (njengaphakathi kwengalo yesiguli nomzimba).Ungaxhumani nensimbi ephansi.Gcina okungenani u-4cm womile phakathi komzimba wesiguli nombhede wensimbi.I-Insulation;
Gwema ukuvuza kwemishini noma ukujikeleza okufushane: ungasondeli ucingo uzungeze izinto zensimbi;ixhume uma kukhona idivayisi yocingo oluphansi;
Ngemva kokuba isiguli sinyakaze, hlola indawo oxhumene kuyo nepuleti elibi noma ukuthi kukhona yini ukususwa;
