What does cautery mean?
Cautery is a noun with two closely related senses: the medical act of burning body tissue to stop bleeding or destroy abnormal cells, and the instrument used to perform that act. Surgeons may employ heat, electric current, or caustic chemicals depending on the situation, and the technique has been practised since antiquity, when hot irons were pressed onto wounds. Today the word appears almost exclusively in medical and veterinary writing, often in compounds such as electrocautery or chemical cautery. Derived from the Greek kautērion, a branding-iron, it shares its root with cauterize and caustic. Though unfamiliar to many lay readers, cautery is a precise and useful term for anyone reading surgical reports or historical accounts of medicine.
The application of a heated instrument, electric current, or caustic agent to living tissue in order to arrest bleeding or destroy diseased or unwanted tissue.
"Cautery was used to control the haemorrhage during the procedure."
An instrument, typically heated or electrified, used to burn or sear body tissue.
"The nurse handed the surgeon a cautery before he made the incision."
The plural is rare and mainly refers to multiple cautery instruments rather than repeated procedures.
"The tray held several cauteries of varying sizes."
The word 'cautery' comes from the Greek kautērion — literally a branding-iron — meaning this everyday surgical term traces back to the practice of searing wounds with hot metal.

Etymology of cautery
Cautery derives from the Latin cauterium, which itself comes from the Greek kautērion, meaning a branding-iron, from kaiein, 'to burn'. The word entered English via Old French and Latin in late Middle English. It shares its Greek root with cauterize, caustic, and, more distantly, holocaust and hypocaust, all of which involve burning or heat.
