Corrigan's Button Cautery, Dublin, Ireland, 1846-1850
Damaged skin tissues could be sealed using this cautery. The button end was held over heat for around 25 seconds and then placed several times on the skin. The skin would react to the heat and become irritated. It was also occasionally used as a form of shock treatment for psychiatric patients. This type of cautery was invented by Irish physician Dominic Corrigan (1802-80) in 1846.
To destroy tissue through contact with a hot implement. To remove warts, etc, or to stop small cuts bleeding.
