A medical procedure that uses electrical current to cut, burn, or remove tissue during surgery without making large incisions.
From electro- (Greek elektron, 'amber') + surgery (Latin chirurgia, from Greek cheirourgía meaning 'hand work'). The term emerged in the early 20th century as electrical technology advanced in medical practice.
Electrosurgery revolutionized surgery by allowing surgeons to cauterize blood vessels as they cut, which dramatically reduced bleeding and infection rates—essentially giving doctors a way to operate with precision while sealing wounds simultaneously.
