风池穴的解剖结构和针刺深度

目的 :探讨风池穴的解剖结构和针刺深度。方法 :随机抽样取 57具较新鲜的成年人尸体 ,其中男尸 2 4具 ,女尸 3 3具 ,采用解剖断面法和解剖层次法进行研究。结果 :向下直刺的解剖结构依次是 :皮肤、浅筋膜、斜方肌与胸锁乳突肌之间、头夹肌、头半棘肌、头后大直肌。针刺的平均危险深度是 49.71mm。结论 :为了安全 ,建议风池穴针刺的深度控制在 3 4.80mm之内

Anatomic Structure and Needling Depth of Fengchi Acupoint

Objective: To probe into the anatomic structure and safe needling depth of Fengchi (GB 20) acupoint. Methods: Fifty-seven fresher adult corpses were randomly selected. Among them, 24 were male and 33 female. Anatomic cross-sectional method and anatomic lamelled method were used to study the anatomic structure and needling depth. Put the studied corpse into the low-temperature refrigerator (below -30 ℃) for 4 days, then the tissues around Fengchi (GB 20) were sectioned horizontally. When the ice melted, the distance from the skin to the surface of the upper end of the spinal cord was detected with an electronic digital ruler. In 6 corpses for lamina analysis, the anatomical structure of GB-20 was observed. Results: The anatomic structures of insertion of an acupuncture needle in order are: skin, superficial fascia, tissues between trapezius muscle and sternocleidomastoid muscle, musculus splenius capitis, musculus semicpinalis, musculus rectus capitis posterior major and membrane atlantooccipitalis posterior. Conclusion: The mean dangerous depth for perpendicular insertion of acupuncture needle is 49.71 mm, and for safe needlingty, it is proposed that the depth for perpendicular needling is within 34.80 mm.
