天突穴针刺安全深度的应用解剖研究

Applied Anatomy Study on Safe Depth for Needling Tiantu (CV22) Point

在60具成人尸体上,采用钢针标定法和层次解剖法,研究天突穴的解剖结构和针刺深度与角度,结果显示:天突穴的解剖结构由浅入深依次是皮肤,浅筋膜,颈深筋膜浅层,左、右胸锁乳突肌起端之间,胸骨颈静脉切迹上方,左、右胸骨舌骨肌之间,胸骨甲状肌,气管前间隙,胸腺,胸膜前界与肺的前缘。向下直刺的平均危险深度为22.5mm,为了保证安全,建议天突穴针刺的深度控制在13mm内。

To probe into the anatomic Structure and safe needling depth and angle of Tiantu point, steely-needle maked method and layer anatomy method were used in 60 adult corpses. The result showed that the anatomic structures from skin to deep are skin, superficialfascia, superficial layer of the deep cervical fascia, between the origin of the left and right stemocleidomastoid, superior of the sternum jugular notch, left and right stem hyoid, sternothy roid, turchea anteriorfissur, thymus, pleure anterior margin and lung margo anterior. The mean dangerous depth of male for perpendicular insertion down ward is 22.5mm. So it is suggested that the depth for perpendicular needling of Tiantu point is within 13mm.
