Vascular does not exist in the intervertebral disk. The nutrient and any excretory things diffuse into the intervertebral disk via the Vertebra body which it adjoins. As year is taken, the nutrient where calcification formation is formed between the intervertebral disk and the Vertebra body, in the blood, diffusion of oxygen and the pH buffer is obstructed. Under anaerobic condition, lactic acid is produced, stimulates nervous end, the non uniqueness occurs painfully. In addition, it falls to deficiency, starts converting the intervertebral disk flatly. From the intervertebral disk it shifts weight abnormally to the surface joint, tension and occurs the back painfully. The shunt coil forms forma, at the same time, on the distance shaft of the needle which can twirl, is wound in spiral condition, the intervertebral disk which is denaturalized with the sleeve which is slid is entered nuclear. The coil does the role of internal shunt, in order to neutralize lactic acid in the center of the intervertebral disk which is denaturalized, the nutrient, pulls oxygen and the cushioning solute from the diffusion area of the top and bottom and is packed. In addition as for the coil, it continues compression, in order to decrease the instability during loading and the Vertebra between the Vertebra, it does also role as the bulk medicine inside the intervertebral disk which was adjusted. Also the terminal strand of the shunt coil and extending from the intervertebral disk, the blood plasma neutralization and pain killing of retreat and lactic acid are promoted from muscle 193 or systemic circulation, the intervertebral disk substrate for regenerating the intervertebral disk is re-constructed.椎間板には血管が存在しない。栄養素および排泄物は、隣接する椎体を通じて椎間板内に拡散される。年を取るにつれて、椎間板と椎体の間に石灰化層が形成され、血中における栄養素、酸素およびpH緩衝剤の拡散を妨げる。嫌気性条件下では、乳酸が産生され、神経終末を刺激し、非特異的疼痛を生じる。加えて、椎間板は欠乏に陥り、平板化し始める。体重は椎間板から面関節へと異常にシフトし、緊張および背痛を生じる。 シャントコイルは、形を成し、かつ、ひねることができる針の遠位シャフト上に、らせん状に巻かれ、スライドするスリーブによって変性した椎間板の核内に投入される。コイルは内部シャントの役割をし、変性した椎
