Acupuncture has been applied in 196 countries for treating diseases,and the safety is a crucial factor affecting the promotion and development of acupuncture.The safe needling depth of acupoints,as a part of acupuncture safety,was analyzed by reviewing previous relevant literature.It is found that the measurement methods used by researchers are diverse,and there are inconsistencies in the research results of the safe needling depth of acupuncture at the same acupoints.More importantly,the international“Cun measurement”for acupuncture needles lacks a unified standard.It is neither the standard body Cun nor the proportional body Cun,but is based on English inches,with arbitrary rounding after metrication,leading to chaos in acupuncture needles.The difference in needle Cun affects the measurement of acupuncture Cun,thus influencing the efficacy and safety of acupuncture.The superposition of errors in needle length and safe acupuncture depth of acupoints leads to the superposition of clinical acupuncture safety risks.Based on the above,it is proposed to restore the Han inch and achieve the unification of the acupuncture inch measurement,the safe acupuncture depth of acupoints and the standardization of needles to improve the safety and international standardization of acupuncture.
