The invention relates to an internal heat type
acupuncture needle which comprises a seal head with a first
electrode, a needle
handle with a second
electrode, a needle body and a needle tip, wherein the end of the seal head is inserted into the needle
handle, the needle
handle, the needle body and the needle tip are in integral connection, the needle body is internally provided with an electrothermal wire and a
copper lead which are mutually connected, the end of the electrothermal wire near the needle tip is contacted with the inner surface of the needle body, the other end of the
copper lead extends into the needle handle and is connected with the first
electrode, and the first electrode, the
copper lead, the electrothermal wire and the second electrode are sequentially communicated to form a closed conduction loop. In the process of
acupuncture therapy, the
heating temperature of the needle body and the heating end length of the needle tip can be set according to the clinical needs,
low voltage and microcurrent can be supplied to carry out work through an external special therapeutic instrument, and the needle tip temperature can keep in a most proper state in the process of therapy, so that the
infrared heat energy of the electrothermal wire in the needle body is directly acted on the focus part without burning a
skin, therefore, the therapy has good effect; and a needle with thinner
diameter can be selected to lighten pains and belonephobia of a patient.
