Electrosurgical units(ESU) chiridzwa che electrosurgical chinoshandisa yakakwira-frequency magetsi kucheka matishu uye kudzora kubuda ropa nekukonzera coagulation.Inopisa matishu apo iyo yakakwira-frequency yakakwira-voltage ikozvino inogadzirwa neanoshanda electrode tip inosangana nemuviri, uye inoziva kupatsanurwa uye coagulation yemuviri tishu, nekudaro kuzadzisa chinangwa chekucheka uye hemostasis.
Iyo ESU inogona kushandisa monopolar kana bipolar modhi
1.Monopolar mode
Mune monopolar mode, dunhu rakazara rinoshandiswa kucheka nekusimbisa tishu.Dunhu rine high-frequency generator, negative plate,connector grounding pad tambouye electrodes.Iyo yekupisa mhedzisiro ye-high-frequency electrosurgical units inogona kuparadza nyama inorwara.Inounganidza yakakwira-density uye yakakwirira-frequency ikozvino uye inoparadza tishu panzvimbo iyo inobata muromo we electrode inoshanda.Solidification inoitika kana tembiricha yetishu kana sero inosangana ne electrode ichikwira kusvika pakuita denaturation yeprotein iri muchitokisi.Iyi chaiyo yekuvhiya maitiro inoenderana ne waveform, voltage, ikozvino, mhando yetishu, uye chimiro uye saizi ye electrode.
2.Bipolar mode
Kuwanda kwechiito kunogumira kumigumo miviri yebipolar forceps, uye kukuvadzwa uye huwandu hwesimba hwesimba hudiki kwazvo pane hwemonopolar.Inokodzera kuvhara tsinga duku dzeropa (diameter <4 mm) uye fallopian tubes.Nokudaro, bipolar coagulation inonyanya kushandiswa mukuvhiya kweuropi, microsurgery, maitiro mashanu, obstetrics uye gynecology, kuvhiyiwa kwemaoko, nezvimwewo. Kuchengetedzwa kwepamusoro-frequency electrosurgical units bipolar coagulation iri kuonekwa zvishoma nezvishoma, uye kushandiswa kwayo kuri kuwedzera zvishoma nezvishoma.
Electrosurgical units inoshanda musimboti
Mukuvhiya kwe electrosurgical, ikozvino inoyerera kubva kuneelectrosurgical Penzuramumuviri wemunhu, uye inoyerera ichibuda pane negative plate.Kazhinji mains edu frequency ndeye 50Hz.Isu tinogona zvakare kuita electrosurgery mune iyi frequency bhendi, asi iripo inogona kukonzera yakawandisa kukurudzira kumuviri wemunhu uye kukonzera rufu.Mushure meiyo frequency yazvino inodarika 100KHz, tsinga nemhasuru hazvichaite kune yazvino.Naizvozvo, iyo yepamusoro-frequency electrosurgical units inoshandura iyo 50Hz ikozvino yemains kuita yakakwirira-frequency ikozvino inodarika 200KHz.Nenzira iyi, iyo yakakwira-frequency simba inogona kupa kurudziro shoma kumurwere.Iko hakuna njodzi yekuvhunduka kwemagetsi kuburikidza nemuviri wemunhu.Pakati pavo, basa replate rakaipa rinogona kuumba chiuno chemazuva ano, uye panguva imwechete kuderedza huwandu huripo huripo paplate ye electrode, kudzivirira ikozvino kubva pakusiya murwere uye kudzokera ku-high-frequency electrosurgical units kuti irambe ichipisa. nyama uye kupisa murwere.
Tichifunga nezvebasa rekushanda repamusoro-frequency electrosurgical units, isu tinofanirwa kutarisisa kune anotevera ekuchengetedza maficha panguva yekushandiswa:
l Kushandiswa kwakachengeteka kwendiro yakaipa
Ikozvino high-frequency electrosurgical units ine yakakwira-frequency yekuzviparadzanisa tekinoroji, uye yakasarudzika yakakwirira-frequency ikozvino inoshandisa chetenegative platesenzira chete yekudzokera kune yakakwirira-frequency electrosurgical units circuit.Kunyangwe iyo yakasarudzika sisitimu yedunhu inogona kudzivirira murwere kubva pakupisa kubva kune imwe dunhu redunhu, haigone kudzivirira kupisa kunokonzerwa nezvinetso neakaipa plate yekubatanidza.Kana nzvimbo yekubatana pakati peplate yakaipa uye murwere haisi yakakura zvakakwana, ikozvino ichave yakanyanyisa munzvimbo duku, uye kutonhora kweplate yakaipa ichakwira, iyo inogona kukonzera kupisa kumurwere.Nhamba dzinoratidza kuti 70% yeanonzi high-frequency electrosurgical units inopisa tsaona inokonzerwa nekukundikana kweplate ye electrode yakaipa kana kukwegura.Kuti tidzivise kupisa kweplate yakaipa kumurwere, isu tinofanirwa kuve nechokwadi chekusangana kwenzvimbo yeplate isina kunaka uye murwere uye mafambisirwo ayo, uye yeuka kudzivirira kudzokorora kushandiswa kweiyo.ndiro inoraswa isina kunaka.
