Related to cauteries: cold cautery
cautery,searing or destruction of living animal tissue by use of heat or caustic chemicals. In the past, cauterization of open wounds, even those following amputation of a limb, was performed with hot irons; this served to close off the bleeding vessels as well as to discourage infection. In modern times cautery is used only on small lesions, e.g., to close off a bleeding point in the nasal mucous membrane or to eradicate a wart or other benign lesion. This is accomplished either by the application of a caustic substance such as nitric acid, or by the use of an electrically charged platinum wire (electrocautery).
Any agent or device used to coagulate or destroy tissue by means of heat, cold, electric current, or caustic chemicals.
