Ironing surgical.. Burning skin or mucous membrane with caustic substances, hot machines or electric current to treat uterine ulcers and appendectomy

Ironing is the burning of the skin or mucous membrane with caustic substances or hot machines or electric current, and rarely used in only a few cases: treatment of uterine ulcers, and removal of appendicitis.
And the origin of the legitimacy of this type is proven in the correct Jabir bin Abdullah that the Prophet sent to Abi ibn Ka'b a doctor and cut off a sweat from him and then his mouth.
