HEATING NEEDLE AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2023/163431

A1

The present invention relates to a heating needle and a manufacturing method therefor, the heating needle having a heating needle handle separately provided above a needle handle so that heat primarily applied to the heating needle handle is diffused into the needle handle, and then is conducted into a needle shaft so that burns can be prevented, the needle shaft being formed of gold, which has relatively good abrasion resistance and tension, rather than of silver, which has relatively poor abrasion resistance and tension, so that pain can be reduced during insertion. The heating needle according to one embodiment of the present invention comprises: the needle shaft to be inserted into the skin; the needle handle, which is provided above the needle shaft and is relatively thicker than the needle shaft; and the heating needle handle, which is formed above the needle handle and is thinner than the needle handle. In addition, the manufacturing method of the heating needle, according to one embodiment of the present invention, comprises: a first step of manufacturing the needle shaft in gold; a second step of manufacturing the needle handle and the heating needle handle in silver; a third step of joining the needle shaft to the needle handle, thereby forming a heating needle; and a fourth step of removing impurities from the heating needle through acid treatment.
