Plural of electrocautery; electrical instruments or devices used to burn or seal tissue during medical or surgical procedures.
Plural of electrocautery, from electro- (electricity) + cautery (burning of tissue, from Latin cautērium). The practice emerged as electricity became available in the late 1800s.
Electrocauteries are often used during surgery to stop bleeding by instantly sealing blood vessels with controlled heat—surgeons can remove tumors or repair tissues with less blood loss than ever before.
