Navigation Image Accuracy Test in Cervical Spine Surgery Using Anatase Spine Surgery Navigation System
Study Details
Study Description
Brief Summary
The "Anatase" Spine Surgery Navigation System used in this study has obtained market approval in Taiwan(MOHW-MD-No.006663) and the United States (510(k) Numbers: K180523 and K220348).
The "Anatase" Spine Surgery Navigation System, also known as an Image Guide System, is indicated for precise positioning of surgical instruments or spinal implants, such as pedicle screw placement, during general spinal surgery. The system uses wireless optical tracking technology to track the position of instruments in relation to the surgical anatomy and register to the relative position in preoperative 3D CT imagery.
The aim of the study is to verify the accuracy of "Anatase" Spine Surgery Navigation System in Image-guided Cervical Spine Surgery. This trial will involve 8 subjects using the approved "Anatase" Spine Surgery Navigation System to collect images before screw implantation, and verify the accuracy of navigation images in cervical spine surgery.

Detailed Description
The "Anatase" Spine Surgery Navigation System, is composed of an Optical Tracker, Computer, No-Touch Reader and Dynamic Reference Frame (DRF). The Optical Tracker is a position sensor, it tracks the position of instruments with DRF by infrared light, allowing the instrument and vertebra to be positioned. The Computer is a touch screen panel PC running the proprietary spine NAVI software that guides the surgical procedure and display the results of the operation and computation. A No-Touch Reader, which attached on the Optical Tracker, is a no-touch sensor to identify instruments. It's a unique design and identification technology allows the instrument to be wirelessly identified, reducing the risk and time required to set up the instrument type. The system can track the position of patient's vertebra and instruments by mounting the DRF on patient's vertebra and instruments.
The "Anatase" Spine Surgery Navigation System is indicated for precise positioning of surgical instruments or spinal implants during general spinal surgery. The system helps to guide surgeons with real-time image and provides preoperative planning and intraoperative control.

Outcome Measures
Primary Outcome Measures
- Difference between the actual and virtual (navigation system) distance of the probe. [during the surgery]
The assessor will measure the distance (mm) of the probe between the actual and virtual (navigation system) images.
- Difference between the actual and virtual (navigation system) angle of the probe. [during the surgery]
The assessor will measure the angle (°) of the probe between the actual and virtual (navigation system) images.
