【Abstract】 Objective: To probe into the anatomic structure and safe needling depth of Jianjing (GB 21). Methods: Fifty-seven fresher adult corpses were randomly selected. Among them, 24 were male and 33 female. Anatomic sagittal sectional and lamelled methods were used to study the anatomic structure and suitable needle-insertion depth. Results:Anatomic structures of the perpendicular sections in order are skin, superficial fascia, deep fascia, trapezius muscle, lateral part of the levator muscle of scapula, serratus anterior muscle, external intercostal muscle, internal intercostal muscle and parietal pleura. If the acupuncture needle tip penetrates the parietal pleura, it will puncture the lung to induce pneumatothorax. When Jianjing (GB 21) punctured, the acupuncture needle should be controlled to advance straight downward, avoiding advancing obliquely toward the medial side of the chest. Conclusion:The mean dangerous depth for perpendicular needling insertion downward is 55.96 mm, and for safety, it is proposed that the depth for perpendicular needle-insertion is within 39.17 mm in patient with medium build.更多还原
