3D Navigation System

Pathkeeper’s 3D navigation system is a user-friendly guided surgery platform that offers real-time anatomical tracking while remaining radiation free and affordable.


Surgery Planning Software

“If you fail to plan, plan to fail”, B. Franklin

Surgery planning has been proven to improve clinical outcomes in spine surgery, however, it has  received limited adoption due to the complexity of current systems. Using AI and proprietary clinical algorithms, we have developed a surgery planning platform that is easy to learn and easy to use When using Pathkeeper’s planning module, the surgeon uploads patient CT or MRI data to a semi-automatic analysis software. Via the platform’s AI-powered tools, the surgeon can review the case and make a more accurate and quantitative decision as to how to perform the surgery. Pathkeeper’s platform naturally uses common resources such as 2D & 3D Dicom viewer, pre-op and intra-op implant planning, cloud sharing between staff (including remote specialists) and PACS Integration to ensure precise planning.

30 Second Calibration

Once in the operating room, the support staff performs a quick calibration and verification procedure to ensure sub-mm accuracy of the system. Pathkeeper’s user friendly system’s surgery preparation process is AI-guided and takes only 30 seconds to set up versus the 15-30 minutes of our competitors’ systems.

Pre-op System Registration

Just before starting the surgery, the surgeon performs a quick preliminary registration (matching) process to verify that the 3D camera captures the scene correctly and matches the CT or MRI data to the patient anatomy. The registration takes less than 30 seconds and doesn’t require use of ionizing radiation. The system consistently takes 3D scans and continuously updates the registration in the vertebra level. Each vertebra is matched with no dependency on the others, making the system immune to spinal  movement due to surgical work (e.g. cage insertion).

The system additionally uses IR light which is immune to interference by the surgery room illumination and doesn’t interfere with the surgeon’s work.

Direct Feedback Mechanism

During surgery, the surgeon is guided by the system and receives feedback on the location and trajectory of the surgical tools. Current systems use either remote screens or various augmented reality methods to give the surgeon feedback. In contrast, Pathkeeper’s solution uses a simple yet intuitive feedback system implemented in its design. LED’s are used on the tracking tool itself to guide the surgeon to the correct clinical position. 

Real-time Tracking

The system offers real-time tracking via the 3D camera, and the anatomical map is updated 10 times per second to support small movement of the patient’s anatomy during surgery. Real-time tracking, combined with sub-mm accuracy, enables device suitability to all different types of procedures including pediatric deformity cases, MISS and cervical procedures.

Unique System Capabilities

Unique system capabilities include direct anatomical tracking, real-time and seamless anatomy map updating, and sub-mm accuracy. This means that the system tracks each vertebra directly, not just the markers, automatically detects anatomical changes, and updates the 3D view accordingly. This ensures that the surgeon has the most accurate and relevant data which assures sub-mm accuracy. The real-time updates enable guided surgery with sub-mm accuracy and can support additional and more complex and sensitive indications in varied procedures.
