Electrosurgery yog dab tsi?
Electrosurgery yog qhov kev phais mob uas siv lub tshuab hluav taws xob tam sim txiav, coagulate, desiccate, thiab / lossis cov nqaij mos. Thaum lub sijhawm ua tiav, qhov ntsuas hluav taws xob ntau zaus (electromeurgical unit) (ESU) yog siv los hloov 60 Hz mus rau ntau dua 300, 000 Hz high-frequency tam sim no, uas tuaj yeem dhau los ntawm tib neeg lub cev yam tsis muaj kev nyab xeeb uas tsis ua rau cov hlab ntsha lossis cov leeg tawm.
Electrocoagulation yog ib qho qauv ntawm kev phais mob hemostasis. HF tam sim no ua kom tsis muaj zog, lub cev qhuav dej thiab ua kom cov hlab ntshav, coagulates thiab yaj hauv cov hlab ntshav thiab txhaws, thiaj li ua tiav lub hom phiaj ntawm hemostasis zoo.
Muaj ob qho yooj yim ntawm hom kev xaim hluav taws xob nyob ntawm hluav taws xob hluav taws xob: monopolar thiab bipolar.
Monopolar Electrosurgery
Hauv monopolar electrosurgery, qhov tam sim no ntws los ntawm ESU mus rau qhov nquag siv hluav taws xob, tus neeg mob, tus neeg mob rov qab ncoo (aka dispersive ncoo lossis nruab nrab electrode) uas tau muab tso rau ntawm tus neeg mob lub cev, thiab thaum kawg rov qab mus rau ESU. Kev xa hluav taws xob hluav taws xob xav tau kom ua tiav ntawm Circuit Court. Txheeb rau Diagram 1 hauv qab no.
Bipolar Electrosurgery
Hauv txoj kev xaim hluav taws xob, yuav tsis siv neeg mob rov qab. Tam sim no ntws los ntawm ESU kom nquag mus electrode, tus neeg mob, thiab tom qab ntawd rov qab los ntawm cov nquag electrode. Nws feem ntau yog hla ntawm ob qho kev sib tsoo ntawm lubcov ntaub so ntswg xav kom tiav hauv Circuit Court. Tam sim no tsis ntws mus rau lwm qhov ntawm tus neeg mob lub cev. Txheeb rau Diagram 2 hauv qab no.
Cov ntawv thov
Tam sim no, monopolar lossis unipolar electrosurgical seev yog cov khoom siv feem ntau siv vim lawv qhov versatility thiab cov hauj lwm zoo. Txawm li cas los xij, cov tswj hwm yuav tsum tau siv kev ceev faj ntxiv thaum siv monopolar nquag electrode thiab cov hluav taws xob dispersive, kom tswj tau cov cua sov ua kom zoo dua thiab zam qhov chaw kub hnyiab. Ntawm qhov tod tes, rau kev phais mob uas qhov tam sim no tuaj yeem ntws los ntawm cov ntaub so ntswg nrog thaj chaw me me, lossis daim ntaub tuaj yeem nkag tau, cov txheej txheem bipolar yuav zoo dua. Hauv qhov no, qhov tam sim no tsuas yog hla ntawm cov lus qhia ntawm lub zog (lossis tweezers), yog li cov hluav taws xob tau txo, yog li cov cua sov thiab kev puas tsuaj rau cov ntaub so ntswg uas nyob ib sab. Ib qho ncoo tsis tsim nyog yog qhov tsim nyog yog li ntawd qhov kev pheej hmoo ntawm kev yoo mispositioning yog tshem tawm. Tsis tas li ntawd, bipolar electrosurgery tuaj yeem ua nyob rau hauv muaj cov kua ntau ntau xws li kua ntsev lossis ntshav, uas muab nws ntau qhov zoo dua monopolar electrosurgery thaum sim ua coagulate hauv thaj chaw ntub dej.
Peb cov khoom lag luam monopolar suav nrog tus cwj mem xim electrosurgical, ENT nqus coagulators, electrosurgical mem hluav nrog suction, thiab laparoscopic hooks.
Peb cov khoom lag luam bipolar suav nrog laparoscopic fenestrated forceps thiab laparoscopic Maryland dissectors.
