The WayPoint™ Stereotactic System is used in conjunction with the microTargeting™ STar™ Drive System for the purpose of functional neurosurgery. The platform attaches directly to a patient via a bone anchored mounting set, and aligns the drive with a selected target. The platform is designed with software to automatically conform to a shape that will align the mounted drive to reach the predetermined or pre-selected targets with sub-millimeter accuracy.
Anchors and Planning
In i
ntracranial surgical applications, the microTargeting™ Platform mounts on three or more small implanted anchors which are detectable in CT and MR imaging studies, which may be acquired a week or more before the surgery. The WayPoint™ Planner software is installed on a portable PC that allows the surgeon the luxury of working with the scan data outside of the operating room environment, at a convenient time and place. All of the functions required to design a patient and procedure customized platform, and to send planning files to production, are included in the portable workstation.
Platform Design
The key to the microTargeting™ Platform is the use of a proprietary and patented modeling pr
ocess. The WayPoint™ Planner software allows the neurosurgeon to easily and rapidly design a custom fixture by the selection of a few critical points, which include target and entry points and fixed reference points provided by an approved fiducial marker/anchor system. After the selection of these points in the scan data, the software virtually builds and provides a visual representation of the platform in place on the patient, including the trajectory and the target. If it is satisfactory to the surgeon, a small, easily transmitted data file is generated which will allow the platform to be fabricated rapidly by a qualified facility and returned within a very short period of time.
Platforms can be created using different heights. To the left, the difference in height options can be compared. The higher the platform, the more room the surgeon will have to work with underneath.
Fixed target microTargeting™ Platform model designs have the drive depth setting to target printed on a leg. Example fixed target depths are shown below corresponding drive depth at target:
- A 110 model puts the electrode at target at a drive setting of 20mm.
- A 120 model puts the electrode at target at a drive setting of 30mm.
- A 130 model puts the electrode at target at a drive setting of 40mm.
- From this it can be seen that the drive setting is always the target depth of the model minus 90
Offsetting/Alternate Track Selection
The 5-track Matrix configuration of the microTargeting™ STar™ Drive System, combined with the unique offsetting feature of the microTargeting™ Platform allows investigation of an area 10 mm in diameter centered on the selected trajectory. In situations where patient anatomy or other reasons exist where the planned entry is unusable, an offsetting hub allows choice of four alternate entries, 3mm offset from the original, all providing trajectories through the original 14mm burr hole and leading to the same planned target. In situations where a 5mm offset from the center track is not adequate to find the expected target, an offsetting hub allows the choice of four alternate target areas, 6mm offset from the original at target depth. The offset target hub provides trajectories that pass through the original entry point and directs all tracks along this new trajectory to the new target area. This system provides the flexibility to move to any of 145 possible tracks within a 22mm diameter area of investigation.
