Qhia luv luv ntawm cov khoom siv hluav taws xob pov tseg pov tseg
High zaus electrosurgical (HF) yog ib qho cuab yeej electrosurgical uas hloov cov tshuab scalpels rau cov ntaub so ntswg.
Nws heats cov ntaub so ntswg los ntawm high-frequency thiab high-voltage tam sim no generated thaum lub zoo electrode tip hu rau tib neeg lub cev, thiaj li mus cuag cov kev sib cais thiab coagulation ntawm cov ntaub so ntswg, yog li ua tiav lub hom phiaj ntawm kev txiav thiab hemostasis.
High-frequency hluav taws xob riam tau siv nyob rau hauv kev kho mob rau ntau tshaj 90 xyoo txij li thaum 1920, thiab tau ntsib plaub tiam ntawm kev hloov los ntawm lub txim plug tawm-high-power tube-high-power triode-high-power MOS raj.
Nrog rau kev txhim kho cov cuab yeej siv kho mob thiab kev kho mob xav tau, cov cuab yeej siv hluav taws xob ua kom yooj yim raws li cov tawv nqaij ntau zaus kuj tau tsim raws li. Tsis tas li ntawd, ntau yam khoom siv tshwj xeeb rau cov cuab yeej phais mob siab (xws li: laparoscopic Metzenbaum txiab, laparoscopic monopolar Maryland strippers, monopolar clamps, laparoscopic bipolar txiab, thiab lwm yam) kuj tau qhib ntau lub sijhawm rau kev kho mob. Kev siv dav dav.
Cov khoom siv phais pov tseg electrode feem ntau muaj ob hom kev ua haujlwm: monopolar thiab bipolar.
Unipolar hom
Nrog monopolar electrosurgical instruments, cov ntaub so ntswg yog txiav thiab coagulated los ntawm ib tug ua tiav Circuit Court uas muaj ib tug high-frequency generator nyob rau hauv lub electrosurgical txiab, tus neeg mob phaj, txuas xov hlau, thiab electrodes.
Hauv ntau daim ntawv thov, tam sim no tau dhau los ntawm tus neeg mob los ntawm cov xov hlau thiab cov khoom siv hluav taws xob, thiab rov qab mus rau lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob ntau zaus los ntawm tus neeg mob phaj thiab nws cov xov hlau.
Cov cua kub ntawm cov khoom siv hluav taws xob ntau zaus uas ua rau cov kab mob puas tsuaj tsis yog los ntawm cov hluav taws xob cua sov lossis cov hniav zoo li electrocautery. Nws concentrates high-frequency tam sim no ntawm high tam sim no ceev kom puas cov ntaub so ntswg ntawm lub point ntawm kev sib cuag nrog lub active electrode ntsis. Coagulation tshwm sim thaum qhov kub ntawm cov ntaub so ntswg los yog cov hlwb nyob rau hauv kev sib cuag nrog los yog nyob ze ntawm lub active electrode nce mus rau ib tug kub ntawm cov proteins nyob rau hauv lub hlwb yog denatured. Qhov kev phais zoo meej no yog txiav txim siab los ntawm qhov waveform, voltage, tam sim no, hom ntaub so ntswg, thiab electrode cov duab thiab qhov loj me.
bipolar
Bipolar coagulation yog muab lub zog hluav taws xob ntau zaus rau tag nrho lub cev cov ntaub so ntswg los ntawm ob lub tswv yim ntawm bipolar forceps, thiaj li ua kom lub cev qhuav dej thiab coagulate cov hlab ntsha ntawm ob kawg ntawm cov bipolar forceps kom ua tiav lub hom phiaj ntawm hemostasis. Nws qhov kev ua haujlwm yog txwv rau ob qhov kawg ntawm cov forceps, thiab qhov kev puas tsuaj rau cov ntaub so ntswg ntawm lub cev thiab cov kev cuam tshuam ntau npaum li cas tsawg dua li cov unipolar sawv daws yuav.
Cov cuab yeej bipolar yog tsim rau kev kaw cov hlab ntsha me thiab cov hlab ntsha. Yog li, bipolar coagulation feem ntau yog siv rau hauv kev ua haujlwm zoo xws li kev phais hlwb, microsurgery, ENT, obstetrics thiab gynecology, thiab phais tes. Kev nyab xeeb ntawm bipolar coagulation tau maj mam lees paub, thiab nws cov ntawv thov tau maj mam nthuav dav.
Cov cuab yeej hluav taws xob tau siv ntau dua hauv kev ua haujlwm endoscopic, xws li: laparoscopy, prostatectomy, gastroscopy, cystoscopy, hysteroscopy thiab lwm yam haujlwm.
Vim nws ib txhij txiav thiab coagulation, high-frequency electrocautery yog dav siv nyob rau hauv kev khiav hauj lwm uas nyuaj rau nkag tau thiab ua nrog txhua yam scalpels (xws li ligation ntawm plab catheters, resection ntawm prostatic urethral masses). Vim nws cov nyhuv coagulation zoo kawg nkaus, nws kuj tau siv dav hauv kev ua haujlwm ntawm qhov chaw los ntshav xws li daim siab, tus po, thyroid, mis, thiab ntsws.
