A multi-parameter controllable automatic fire-acupuncture instrument was developed by integrating traditional fire needling with modern medical device technology. A gun-like appearance was designed for easy hand-held operation

the electromagnetic induction was for heating needle body

a scale knob was for controlling the needle insertion depth

the combination of electromagnetic ejection and spring return was for the precise control of the needle retention time; and the changeable single ste-rile needle or multiple needles were adopted to meet individual demand

obtain high efficiency and prevent infection. All of these designs are associated with the overall process control system to ensure the exact controllability of needle body temperature

needling density

insertion depth and needle retention time. Besides

this device is advantageous at handy and aseptic operation with high efficiency

conformability and visualization. In this research

this instrument was tested in animals for the impacts of automatic fire needling on skin damage and fur growth. It is found that the accurate control of each parameter is of the significant advantage in the safety and effectiveness of treatment

which lays a solid foundation for the subsequent systematic review on safety and effectiveness.
