导向器

Imaging-based measurements of introversion angle, declination angle, entry point and distance of spinous process at the horizontal plane are important data for percutaneous vertebroplasty. According to pedicle shape features at different stages, included angle, puncture point, path and depth, the vertebroplasty could be performed accurately and safely with reduced damage. Moreover, reliable data are provided for the design of a three-dimensional puncture-oriented device.

提示基于影像学所测量的内倾角、下倾角度、进针点与棘突在水平面上的距离等数据是进行经皮穿刺椎体成形术操作时的重要依据，根据不同阶段椎弓根形态学特点、夹角及确定穿刺点、穿刺路径和穿刺深度可以准确、安全进行操作，减少了损伤，也为设计一种三维立体穿刺导向器提供了可靠数据。
