SURGERY PLANNING

PRE-SURGERY SCAN UPLOADED

The patient’s CT data is uploaded into the PathKeeper system. 

SURGERY PLANNING ON WORKSTATION

The proprietary software is state-of-the-art and was developed specifically for spinal procedures. The CT scan is enhanced, enabling the surgeon to make highly accurate and quantitative decisions for the surgery trajectory.

SET UP & REGISTRATION

TOOL CALIBRATION:

The operating tools are equipped with markers and undergo a quick calibration process to ensure accurate coverage and tracking throughout the surgery. This set up is significantly shorter than other available navigation systems – a matter of seconds versus minutes.

REGISTRATION PROCESS:

Once the patient is prepped and the target anatomy is exposed, the 3D laser camera captures a surface scan. A registration process is then performed so that the surgeon can verify that the CT data is accurately matched to the surface data. The system takes 3D scans continuously and updates the registration constantly in real-time.

NAVIGATION & IMPLANT INSERTION

CONTINUOUS ANATOMICAL TRACKING 

The 3D camera continuously tracks the movement of the patient’s anatomy and the surgical tools. The PathKeeper software corrects the anatomical map multiple times per second to accurately reflect the operative field. The system is uniquely capable of segmenting, detecting and tracking each vertebra independently (not just the patient reference marker) making it immune to spinal movement due to surgical work (e.g. cage insertion, retraction, etc.). Furthermore, the system uses NIR light which is unhindered by the surgical illumination and does not interfere with the surgeon’s work.

GUIDED IMPLANT INSERTION

The navigation system guides the surgeon throughout the procedure and provides real-time feedback on the location and trajectory of the surgical tools. Once the location of the pedicle screw has been pre-planned, the system generates a superimposed image of the planned placement on the CT scan and guides the physician to align the navigated screw on the preoperatively planned one.
