Iodophor cannot soften titanium nails, because iodophor is a kind of complexed iodine, which contains polyvinylpyrrolidone indeterminate conjugate, mainly used for sterilization, can kill common bacteria, fungi and some viruses, etc., which does not have corrosive effect, and can not make the titanium nails corroded off or dislodged. And titanium nails generally contain titanium components and metals, stability is very good, will not be corroded because of commonly used disinfectants or antibiotics. Therefore, if there is a local wound or the need to disinfect the digestive tract, it is safe to use commonly used disinfectants. Even if some of the titanium nails fall off, it is not due to the disinfectant, but due to the body’s rejection reaction. If there is any obvious discomfort or bleeding due to titanium nail dislodgement after using disinfectant, you need to go to the surgery department or emergency department of the hospital for observation and treatment in time, and do not handle it on your own to prevent delaying the condition.
