[ technical field ] A method for producing a semiconductor device
The utility model relates to a medical treatment field especially relates to a supplementary director of puncture of intervertebral foramen through pedicle of vertebral arch location.
[ background of the invention ]
Spinal disorders are caused by one or more individual vertebrae or discs that are abnormal due to disease or trauma. In these pathological situations, fusion of adjacent vertebral components can be used to restore normal vertebral function, achieve a stable state, protect neural structures, or to relieve patient discomfort. There are a variety of spinal fixation systems used to stabilize the spine to achieve bone fusion. Most of these fixation systems utilize fixation elements such as rods or plates that are connected to screws threaded into the vertebral bodies, facets or pedicles. Since the outer surface of the vertebral body is typically non-planar and the structure of the spine is relatively complex, it is important that the fixation elements (e.g., rods, plates, wires, staples, or screws) be properly aligned when they are inserted into the spine. Improper alignment may result in improper or unstable placement of the fixation elements or separation of the fixation elements. However, in practice, achieving and maintaining accurate positioning and guidance of the fixation elements has proven to be quite difficult. This complexity of positioning difficulty is further compounded by the fact that the angle of alignment of the fixation device through one vertebral body or pair of vertebral bodies, resulting from individual differences in spinal curvature and physiological anatomy, is unique for each individual.
Accordingly, there is a need for a guide system and tool for accurate placement of spinal fixation elements.
