This paper provides the historical evolution of fire needle device and summarizes its application characteristics. Cauterized needling is the origin of fire needling technique. The fire needling technique is developed from "cauterized needling and warm compressing with herbal medicine" to "medicinal fire-needling" and "sulfur fire needling" in later generations. The needles used in cauterized needling are derived from nine ancient needles

such as filiform needle

sharp-edged needle and round-sharp needle

which is developed to be different forms

named

single-tip needle

three-edged needle and flat-tip needle. Armature

wrought iron

firecracker iron and silver comb had been used as materials in ancient time; and in modern time

the needles are made from stainless steel and tungsten-based high density cemented carbide to meet the requirements of high-temperature operation of fire needle. These devices used in fire needling technique have strengthened the therapeutic effect of cauterized needling

and obtained the unique clinical effect

such as inducing sweat to remove exterior syndrome

dispelling exogenous pathogens

removing blood stasis and cutting off the foci by cauterization. It is suggested that the standardization and innovation of acupuncture needle is important to promote its application and expansion.
