Iiyunithi zotyando lombane(ESU) sisixhobo sotyando lwe-electrosurgical esisebenzisa i-high-frequency current yombane ukusika izicubu kunye nokulawula ukopha ngokubangela ukujija.Itshisa izicubu xa i-high-frequency high-voltage current eyenziwa yi-electrode tip esebenzayo ekunxibelelaneni nomzimba, kwaye iqonda ukuhlukana kunye nokudibanisa kwezicubu zomzimba, ngaloo ndlela ifezekisa injongo yokusika kunye ne-hemostasis.
I-ESU inokusebenzisa i-monopolar okanye i-bipolar mode
1.Imo yeMonopolar
Kwimo ye-monopolar, isiphaluka esipheleleyo sisetyenziselwa ukusika kunye nokuqinisa izicubu.Isekethe iqulethe ijenereyitha ephezulu, ipleyiti engalunganga,isinxibelelanisi iphedi intambokunye nee-electrodes.Impembelelo yokufudumeza yeeyunithi eziphezulu ze-electrosurgical inokutshabalalisa izicubu ezigulayo.Iqokelela i-high-density kunye ne-high-frequency current kwaye itshabalalisa izicubu kwindawo apho idibanisa nencam ye-electrode esebenzayo.Ukuqiniswa kwenzeka xa ubushushu bezicubu okanye iseli edibana ne-electrode iphakama ukuya kwi-denaturation yeprotheni kwiseli.Esi siphumo sotyando sichanekileyo sixhomekeke kuhlobo lwamaza, i-voltage, yangoku, uhlobo lwethishu, kunye nokumila kunye nobukhulu be-electrode.
2.Imowudi yeBipolar
Uluhlu lwesenzo lulinganiselwe kwiziphelo ezimbini zei-bipolar forceps, kunye nomonakalo kunye noluhlu lweempembelelo ze-forceps zincinci kakhulu kune-monopolar.Kufanelekile ukuvala imithwalo yegazi encinci (ububanzi <4 mm) kunye neebhubhu ze-fallopian.Ngoko ke, i-bipolar coagulation isetyenziswa ikakhulu kutyando lobuchopho, i-microsurgery, iimpawu ezintlanu, i-obstetrics kunye ne-gynecology, utyando lwesandla, njl.
Iiyunithi zotyando lombane umgaqo wokusebenza
Kutyando lwe-electrosurgical, umqukuqela wangoku usuka kwielectrosurgical Ipensileemzimbeni womntu, kwaye iphuma kwi-negative plate.Ngokwesiqhelo amaza omoya wethu yi-50Hz.Sisenokwenza i-electrosurgery kule bhendi yefrikhwensi, kodwa yangoku inokubangela uvuselelo oluninzi kumzimba womntu kwaye ibangele ukufa.Emva kokuba i-frequency yangoku idlula i-100KHz, imithambo-luvo kunye nezihlunu azisayi kusabela ngoku.Ke ngoko, iiyunithi ze-electrosurgical ze-high-frequency ziguqula i-50Hz yangoku ye-mains ibe yi-high-frequency current edlula i-200KHz.Ngale ndlela, amandla aphezulu-amandla anokubonelela ngokuvuselela okuncinci kwisigulane.Akukho ngozi yokutshatyalaliswa kombane emzimbeni womntu.Phakathi kwabo, indima yepleyiti engalunganga inokwenza i-loop yangoku, kwaye kwangaxeshanye inciphise ukuxinana kwangoku kwipleyiti ye-electrode, ukuthintela umsinga ukuba ushiye isigulane kwaye ubuyele kwiiyunithi ze-electrosurgical high-frequency ukuze uqhubeke nobushushu. izicubu kunye nokutshisa isigulane.
Ngokubhekiselele kumgaqo wokusebenza weyunithi ye-electrosurgical ephezulu, kufuneka sithathele ingqalelo le miba ilandelayo yokhuseleko ngexesha lokusetyenziswa:
l Ukusetyenziswa ngokukhuselekileyo kwe-negative plate
Iiyunithi zangoku ze-high-frequency electrosurgical units zixhotyiswe ngetekhnoloji ye-high-frequency isolation, kwaye i-high-frequency current ekwanti isebenzisa kuphelaipleyiti embinjengeyona ndlela yodwa yokubuyela kwi-high-frequency electrosurgical units circuit.Nangona inkqubo yesekethe yodwa inokukhusela isigulane ekutshiseni kwisiphaluka esingesinye, ayikwazi ukuphepha ukutshisa okubangelwa iingxaki ngoxhumo olubi lweplate.Ukuba indawo yoqhagamshelwano phakathi kweplate engafanelekanga kunye nesigulane ayinkulu ngokwaneleyo, okwangoku kuya kugxininiswa kwindawo encinci, kwaye ukushisa kweplate engafanelekanga kuya kunyuka, oku kunokubangela ukutshisa isigulane.Ubalo lubonisa ukuba i-70% yeeyunithi ezixeliweyo ze-electrosurgical ezitshisa iingozi zibangelwa ukusilela kwepleyiti ye-electrode engalunganga okanye ukuguga.Ukuze ugweme ukutshiswa kwepleyiti embi kwisigulana, kufuneka siqinisekise indawo yoqhagamshelwano yeplate engalunganga kunye nesigulane kunye nokuziphatha kwayo, kwaye ukhumbule ukuphepha ukusetyenziswa ngokuphindaphindiweyoipleyiti enegative elahlwayo.
l Indawo yofakelo efanelekileyo
Zama ukuba kufutshane kangangoko kwindawo yotyando (kodwa ungabi ngaphantsi kwe-15cm) kunye nommandla we-blood otyebileyo wemithambo yegazi;
Susa iinwele kwisikhumba sendawo kwaye uzigcine zicocekile kwaye zomile;
Musa ukuwela indawo yokusebenza ekhohlo nasekunene, kwaye ube ngaphezulu kwe-15cm kude ne-electrode yeECG;
Akufuneki kubekho ukufakelwa kwesinyithi, i-pacemakers, okanye i-electrodes ye-ECG kwi-loop;
Icala elide leplate lisondele kwisalathiso se-high-frequency current.
l Nika ingqalelo xa ufaka i-negative plate
Ipleyiti kunye nesikhumba kufuneka zidibaniswe ngokuqinileyo;
Gcina ipleyiti yepolar ithe tyaba kwaye inganqunyulwa okanye isonge;
Gwema ukucwina iipleyiti ze-polar ngexesha lokubulala iintsholongwane kunye nokuhlamba;
Abantwana abangaphantsi kwe-15Kg kufuneka bakhethe iipleyiti zeentsana.
l Eminye imiba efuna ukuqwalaselwa
Khangela ukuba unikezelo lwamandla kunye nemigca ye-electrode yaphukile kwaye iingcingo zetsimbi zibonakaliswe;
Qhagamshela iElectrosurgical Pensilekumatshini, qalisa ukuzijonga, kwaye ulungelelanise amandla aphumayo emva kokuba ibonise ukuba ipleyiti engalunganga ifakwe ngokuchanekileyo kwaye akukho nto ibonisa;
Kuphephe ukutshiswa kwe-bypass: amalungu esigulana asongelwe ngelaphu aze alungiswe ngokufanelekileyo ukuphepha ukudibana kwesikhumba (njephakathi kwengalo yesigulana kunye nomzimba).Musa ukudibanisa nentsimbi ephantsi.Gcina ubuncinci be-4cm yokoma phakathi komzimba wesigulane kunye nebhedi yentsimbi.I-Insulation;
Gwema ukuvuza kwezixhobo okanye isiphaluka esifutshane: musa ukuvuthela ucingo kwizinto zetsimbi;yidibanise ukuba kukho isixhobo socingo oluphantsi;
Emva kokuba isigulane sihamba, khangela indawo yoqhagamshelwano yepleyiti engalunganga okanye ukuba kukho nayiphi na indawo yokufuduka;
