;The spine surgery of pedicle screws implantation requires relatively high accuracy and rich clinical experience. Due to the fact that the spinal structure, pedicle and spinal nerves are so close to each other, even the slightest error occurred may induce spinal nerves damage and cause severe neurologic deficits. Thus, how to implant pedicle screws successfully has become a vital issue. In traditional surgery, doctors acquire patients’ imange before surgery by two-dimensional images for the diagnosis and surgical planning. However, every patient is an independent individual so as to its anatomical position, hence ,wheather making operation smooth and successful depends on surgeon’s professional judgment and extensive clinical experience. All the above factors have shown the uncertainty and difficulty of traditional surgery. Based on the above shortcomings of traditional surgery, we hope to develop computer-assisted navigation system that can be applied in clinical practice with pedicle screw implantation. And the system can not only shorten the time of surgeon’s cultivation but also makes the operation safer.
This study consists of a series of experiments based on our original navigation equipment in our laboratory. At first, we used CT-based navigation system for the actual surgical operation to evaluate the practicability of navigation surgery for the operation of pedicle screw implantation. Although the results of experiments seems positive, when compared with minimally invasive surgery, this navigation mode is out of date.Thus,the following laboratory and practical operation was then replaced with the C-arm guidance system, which is developed by our own laboratory to evaluate its accuracy. The outcome showed when we synchronize the patient’s breathing and image capturing during the surgery, the accuracy of the operation is relatively perfect. Our navigation system can provide real time position of tools in order to reduce the radiation exposure. The planning of screws pathway is also important. Therefore, according to the research of 2D-3D calibration made by our laboratory, we offer a more time-saving and accurate calculation to provide three-dimensional information about sagittal and axial plane for planning the surgery pathway.
