Vista SpineNova
The most common reason for persistent, chronic lower back pain is the instability or breakdown of the elements in the spine which provide stability and support to the body. Spinal fusion is the union of two vertebral bodies to prevent instability in the spine, relieve pressure on the spinal cord or nerves which emanate from the spine, and restore structure and mobility to the patient.
In a typical spinal fusion procedure, there are three main elements to the operation:
- Decompression, or discectomy, where the damaged or collapsed intervertebral disc fragments are removed, and Endplate Preparation, which prepares the intervertebral space for cage insertion and fusion. The SpineNova performs complete autonomous discectomy and endplate preparation in under 3 minutes.
- Interbody fusion implant, the replacing of the now-removed disc with a new intervertebral support structure (the “cage”), as well as bone graft elements to help the vertebrae regain more structural strength. SpineNova provides highly accurate trajectory guidance for optimal cage insertion.
- Pedicle screw insertion, which fixes the rods to the spine and provides the main support to the repaired section of the spine. SpineNova’s integrated navigation and guidance system provides best in class trajectory planning and navigation for pedicle screw insertion.
Surgeries can be done either with an open surgery approach or a minimally invasive approach. Open surgery is invasive and results in more blood loss, longer recovery times, higher risks, and introduces more risk to the patient. Vista’s solution enables minimally invasive spinal surgeries (MIS TLIF) which reduce operating times and improve patient outcomes.
Because existing surgical procedures are by and large all done manually, the procedure requires long hours, high stress and physically demanding work by the surgeon for each procedure done. The Vista solution will perform complete spinal discectomy automatically, with automated steering and navigation, achieving 100% discectomy results in under 3 minutes. The one-pass operation also does endplate preparation. The Vista solution will still provide state of the art imaging and navigation capabilities, and more procedural support will be added to the Vista platform over time, such as laminectomy and automated cage insertion.
Challenges with Existing Surgeries and the Vista Robotics Advantages
Manual Spinal Fusion Surgeries
The Vista Robotics Advantages
- All procedures rely on manual strength and dexterity

- The average surgeon can typically achieve less than 50% disc fragment removal
- An entire surgery can take up to 2 hours and be physically taxing
- Incomplete discectomy can lead to fusion complications
- Automated discectomy and endplate preparation
- 90%+ complete disc fragment removal in 3-5 minutes
- State of the art imaging and pedicle screw navigation
- 20-30 minutes reduced operating time and time under anesthesia
- Improved fusion outcomes due to quality of procedures
- Extensible to robotic assisted laminectomy
