The Cori Surgical System gives surgeons greater accuracy for prosthetic implants.

Description:
Smith and Nephew’s Cori Surgical System for knee replacements is a pioneering robotic navigation system that obtains all the information that a surgeon needs in real time during the procedure. No pre-operative CT scans or MRIs are needed.

The heart of the Cori Surgical System is the ATRACSYS tracking system. The compact ATRACSYS fusionTrack 500 is composed of two cameras designed to detect and track fiducials (reflective spheres, disks and/or IR-LEDs) with high precision in real time video streams. Triangulation enables retrieving 3D position of each fiducial with sub-millimeter accuracy.

Analysis:
During the knee replacement procedure, the CORI system works in conjunction with a surgeon’s skilled hands to achieve accurate positioning of the knee implant based on the patient’s unique anatomy. The process starts with the surgeon registering the existing knee topology using the robotics-assisted hand piece.

With that information, the system calculates the perfect fit of the implant and instructs the surgeon on how much material needs to be removed and exactly where to remove the material in order to prepare the ideal surface for the implant.

The CORI Surgical System enables a surgeon to more precisely fit an implant, which in turn produces better outcomes for the patient and a shorter recovery time. – Mike Oitzman
