The invention relates to the technical field of
medical instruments, and discloses a fire needle heating device for
thermal therapy, which comprises a gun-type shell, a fire needle pushing mechanism and a
ceramic heating element, a rack is mounted on the gun-type shell, a non-magnetic sleeve is mounted on the rack, an
electromagnetic heating unit is mounted in the non-magnetic sleeve, and the
ceramic heating element is mounted in the non-magnetic sleeve. A stainless steel sleeve containing heat conduction oil is further installed in the non-magnetic sleeve, an annular disc frame is arranged on one side of the non-magnetic sleeve, a plurality of limiting type sleeves are installed on the annular disc frame, limiting type shaft bodies are installed on the limiting type sleeves, positioning sleeves are installed at one ends of the limiting type shaft bodies, and needle bodies are installed in the positioning sleeves. According to the fire needle heating device for
thermal therapy, the stainless steel sleeve and heat conduction oil in the stainless steel sleeve are heated through the
electromagnetic heating unit, the needle tip end of the needle body is preheated through the stainless steel sleeve and a heat conduction
coating on the stainless steel sleeve, the needle body is heated through the
ceramic heating element, and therefore in the needle retaining process, the needle tip end of the needle body is heated; and the
heating time can be effectively shortened by preheating the plurality of needle bodies.
