Abstract
The invention discloses an individualized lumbar pedicle screw placement guiding device. The individualized lumbar pedicle screw placement guiding device is composed of a guiding hole, a holding rod and a connecting body. The guiding hole is of a hollow tubular structure with the axis consistent with the pedicle axis; the holding rod is a stabilizing structure during a surgical operation and can perform fine adjustment on the position of the pedicle guiding device on the lumbar vertebra; and the connecting body is a structure with the surface capable of being attached to a vertebra plate and a transverse process surface, and a posterior longitudinal ligament complexus structure is avoided. The individualized lumbar pedicle screw placement guiding device is used for accurate place-in of a pedicle screw, the posterior longitudinal ligament complexus structure is reserved, and the device is convenient and easy to use.
