After initially cleaning the skin with soapy water and clean water, a disinfection forceps is used to hold a cotton ball or gauze soaked with a disinfectant, and wiping disinfection is carried out in accordance with the disinfection sequence. When usually using iodophor for disinfection, it needs to be wiped 2 - 3 times; if using iodine tincture for disinfection, alcohol is required for iodine removal to avoid irritation and damage to the skin caused by iodine tincture. Special part treatment: For deep surgeries such as joint cavities and bone marrow cavities, it may be necessary to rinse with sterile saline or other special rinsing solutions after disinfection to further reduce bacterial residues.
