Smith+Nephew deploys robotic system for orthopedic surgery


Concept: UK medical device company Smith+Nephew (SN) has deployed CORI, a wearable robotic system for total and partial knee replacement surgery. The new system allows surgeons to measure, plan and perform knee surgery customized to patient anatomy. The company says the new robotic system increases the skills of the orthopedic team to improve the accuracy and outcome of knee surgery.

Nature of the disturbance: SN says the new robotic system is compact and fully mobile and integrates a 3D intraoperative imaging system with an advanced robotic sculpting tool. Surgeons can use a pointer tool to highlight the bone surface that needs to be removed. Then they can take advantage of a hand-held cutting tool with a robotic feature that automatically stops the tool’s burr rotation when it is outside the painted area. It requires minimal setup time and can be moved to different operating theaters to optimize patient flow in surgical units. The SN system allows the patient to have a knee replacement that can be form-fitted and aligned to the patient’s specific anatomy. The robotic system does not require CT scans or preoperative imaging and has the potential to improve both implant placement accuracy and operational efficiency.

Outlook: Robot-assisted orthopedic surgery is gaining traction around the world. It is claimed to have various benefits, including improved patient-reported outcome measures (PROMs), reduced length of hospital stays, and faster return to an active lifestyle for patients. SN is introducing CORI to different geographies including Europe, Australia, New Zealand, India and Canada. The company aims to introduce new applications for the CORI robotics platform, including orthopedic pathologies.
