We have devised a new drill burr that is particularly suitable for an anterior approach to the spinal cord. The drill burr is conical in shape, with a shaft attached to its top and fine diamond edges on the curved slope, but not on its tip. The bone is scraped off while the burr is being gently pulled up but not pressed down. This new drill burr has proved to be most useful in safely removing osteophytes and hypertrophied uncovertebral joints without damaging the already compromised spinal cord.
我们设计了一种新型钻磨头，特别适用于脊髓前路手术。该钻磨头呈圆锥形，顶部连接有轴，弯曲斜面上有精细的金刚石边缘，但尖端没有。在轻轻向上提拉钻磨头而不是向下按压时刮除骨质。这种新型钻磨头已证明在安全去除骨赘和肥大的钩椎关节而不损伤本已受损的脊髓方面非常有用。
