Lub tshuab electrosurgery siab npaum li cas?
High-frequency electrosurgical riam (high-frequency surgical instrument) 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 high-voltage tam sim no generated los ntawm cov zoo electrode tip thaum nws nyob rau hauv kev sib cuag nrog lub cev, thiaj li kom paub qhov sib cais thiab coagulation ntawm lub cev nqaij daim tawv, thiaj li mus cuag lub hom phiaj ntawm kev txiav thiab hemostasis.
txoj cai ua haujlwm:
Electrosurgery muaj ob hom kev ua haujlwm tseem ceeb: monopolar thiab bipolar.
Unipolar hom
Nyob rau hauv hom monopolar, cov ntaub so ntswg raug txiav thiab coagulated nrog ib tug ua tiav Circuit Court uas muaj ib tug high-frequency generator nyob rau hauv lub high-frequency electrosurgical unit, neeg mob paddles, txuas leads, thiab electrodes. Hauv cov ntawv thov feem ntau, tam sim no tau dhau los ntawm tus neeg mob los ntawm cov khoom siv lead ua thiab electrodes, thiab los ntawm tus neeg mob cov ntaub qhwv thiab coj rov qab mus rau lub tshuab hluav taws xob ntawm HF electrosurgery.
Cov nyhuv cua sov ntawm high-frequency electrocautery, uas rhuav tshem cov kab mob, tsis yog tshwm sim los ntawm cov cua kub electrode los yog lub ntsis, ib yam li cov ntaub ntawv nrog electrocautery. Nws concentrates high-frequency tam sim no nrog high tam sim no ceev thiab ncaj qha rhuav tshem cov ntaub so ntswg nyob rau hauv qab 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 hlwb nyob rau hauv kev sib cuag nrog los yog nyob ib sab ntawm lub active electrode nce mus rau lub point uas cov proteins nyob rau hauv lub hlwb denature. Qhov kev phais zoo meej no yog txiav txim siab los ntawm lub waveform, voltage, tam sim no, cov ntaub so ntswg hom thiab electrode. puab thiab loj.
Txhawm rau kom tsis txhob ua kom cov ntaub so ntswg kub thiab hlawv tus neeg mob thaum tam sim no tawm ntawm tus neeg mob thiab rov qab mus rau HF electrosurgical chav tsev, tus neeg mob paddle nyob rau hauv ib qho khoom siv monopolar yuav tsum muaj thaj tsam loj nyob rau hauv kev sib cuag nrog tus neeg mob kom muab lub impedance qis thiab qis tam sim no. ceev ceev channel. Qee lub tshuab hluav taws xob hluav taws xob ntau zaus siv hauv cov kws kho mob cov chaw ua haujlwm muaj qhov tsis tshua muaj tam sim no thiab qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom siv cov tshuab siv hluav taws xob siv hluav taws xob loj siv tam sim no tsis siv neeg cov ntaub qhwv.
Cov khoom tso tawm uas tau muab cais tawm hauv av ua rau tam sim no ntawm kev siv hluav taws xob ntau zaus tsis tas yuav muaj kev pabcuam hauv nruab nrab ntawm tus neeg mob thiab hauv av, yog li txo qhov kev pheej hmoo ntawm kev kub hnyiab ntawm lub cev uas tuaj yeem cuam tshuam nrog hauv av. Nrog rau hauv av-raws li system, qhov kev pheej hmoo ntawm kev kub nyhiab yog ntau dua nrog cov khoom siv hluav taws xob insulated.
Hom Bipolar
Bipolar coagulation yog muab lub zog hluav taws xob ntau zaus rau lub cev nqaij daim tawv los ntawm ob lub tswv yim ntawm cov hlab ntsha bipolar, kom cov hlab ntsha nruab nrab ntawm ob qhov kawg ntawm lub cev bipolar forceps yog lub cev qhuav dej thiab coagulated kom ua tiav lub hom phiaj ntawm hemostasis. Nws qhov kev ua haujlwm tsuas yog txwv rau ob qhov kawg ntawm cov tweezers, thiab qhov kev puas tsuaj ntawm cov ntaub so ntswg ntawm lub cev yog me dua li ntawm txoj kev monopolar, thiab nws yog qhov tsim nyog rau kev sib khi cov hlab ntsha me me (inch.<4mm) and="" fallopian="" tubes.="" therefore,="" bipolar="" coagulation="" is="" mostly="" used="" in="" more="" delicate="" operations="" such="" as="" brain="" surgery,="" microsurgery,="" ent,="" obstetrics="" and="" gynecology,="" and="" hand="" surgery.="" the="" safety="" of="" bipolar="" coagulation="" is="" gradually="" being="" recognized,="" and="" its="" use="" is="" gradually="">
