睛明穴的解剖学研究

目的探讨睛明穴的解剖结构、针刺深度和方向,为临床针刺睛明穴提供解剖学依据.方法解剖观测48例成人尸体眼眶.结果睛明穴直刺进针,针尖穿经的结构为皮肤、皮下组织、睑内侧韧带、内直肌、眶脂体.针体上方有眼动脉、筛前动脉及伴行的鼻睫神经通过.皮肤刺入点至筛前动脉平均距离为(18.25±4.45) mm,角度为与针体向上成(12.5±5.5)°,皮肤刺入点至视神经管前极平均距离为(43.37±7.84) mm.结论睛明穴进针应避免向后上斜刺或偏上方深刺,以免刺破筛前动脉引起眶内出血;同时直刺进针深度一般不超过30.36 mm,以免损伤视神经管前极.

Anatomical study on Jingming (BL 1)

OBJECTIVE: To explore the anatomical structures, and depth and direction of needling at Jingming (BL 1), so as to provide anatomical basis for its clinical application. METHODS: Forty-eight adult orbital specimens were observed by dissection. RESULTS: When a needle was vertically inserted into Jingming (BL 1), the needle tip will past through the skin, subcutaneous tissue, medial palpebral ligament, medialis rectus and orbital adipose body. Above the body of the needle, there are ophthalmic artery, anterior ethmoidal artery and nasociliary nerve. The average distance between the skin at the punctured point and the anterior ethmoidal artery is (18.25 +/- 4.45) mm, with an angle of (12.5 +/- 5.5) degrees, and the average distance between the skin at the punctured point and the optic nerve tunnel frontal point is (43.37 +/- 7.84) mm. CONCLUSION: To avoid bleeding caused by injuring the anterior ethmoidal artery, acupuncture at Jingming (BL 1) should avoid deeply inserting needled back-upwards and upwards, and the needling depth should not exceed 30.36 mm to avoid injury of the optic nerve tunnel frontal point.
