Intended Use

The Paradigm System is a stereotaxic image guidance system intended for the spatial positioning and orientation of spinal surgical instruments used by surgeons during open surgical procedures with appropriate bone preparation. The device is indicated for posterior approach spine surgery where reference to a rigid anatomical structure that can be identified on CT derived patient images for pedicle screw cannulation of the thoracic to sacrum vertebrae.

Device Story

Paradigm System is a stereotaxic image guidance system for spinal surgery. Inputs: preoperative CT scans; real-time camera imaging of surgical site via Prism Sensor Array. Operation: system segments CT data to generate 3D models of vertebrae; intraoperative registration matches live anatomy topography to 3D model; creates common coordinate space; overlays virtual information onto live anatomy for guidance. Output: visual display on external monitor showing instrument position/orientation relative to patient anatomy. Used in OR by surgeons. Benefits: precise instrument placement during pedicle screw cannulation; improved spatial positioning.

Preoperative CT data is<br>uploaded to the console and the system<br>software generates a 3D model of the<br>patient's operative vertebrae. The 3D<br>model is used for preoperative<br>planning such as implant placements<br>or instrument trajectories. During the<br>procedure, once the patient's anatomy<br>is exposed, the Prism Sensor Array<br>acquires imaging to match the<br>topography of the live anatomy to the<br>3D model. This intraoperative<br>registration of live anatomy to the 3D<br>model creates a common coordinate<br>space between the preoperative CT<br>data and the patient anatomy. This<br>enables virtual information to be<br>overlaid on the live anatomy during<br>the procedure for intraoperative<br>guidance. | The Envision 3D system<br>provides image registration<br>between preoperative scan data<br>and data captured<br>intraoperatively from the<br>Envision 3DTM integrated<br>structured light scanner<br>and/or user selected points. The<br>system provides guidance data<br>by displaying the<br>locations of wireless optically<br>tracked Envision 3DTM Spinal<br>Instruments (examples<br>include pedicle probe and awl)<br>relative to the patient. Position<br>and orientation data of<br>tracked Envision 3DTM Spinal<br>Instruments are linked to the<br>preoperative scan data using<br>the Envision 3DTM workstation. | Subject device<br>uses light field<br>where predicate<br>uses structured<br>light scanner.<br>Subject device<br>segments each<br>vertebra where the<br>predicate as if it<br>were a single<br>anatomical body. |
