The CORI surgical system is an advanced and efficient handheld robotics-assisted platform for total and unicompartmental knee arthroplasty. The solution is ideal for outpatient surgery and ambulatory surgical centres (ASCs). It is developed by Smith+Nephew and backed by the company’s Real Intelligence digital solution.

The CORI surgical system received 510K clearance from the US Food and Drug Administration (FDA) for human use in February 2020. It was launched in Canada, India, Australia, New Zealand and the UK in 2021.

Smith+Nephew’s Cori surgical system design details

The CORI solution is a compact surgeon-controlled handheld robotics system comprising a 3D intra-operative imaging system with a sophisticated robotic sculpting technology. The system’s modular design allows it to be expanded across the orthopaedic service line.

CORI utilises a passive infrared tracking camera more than four times faster than that of its predecessor, the NAVIO Surgical System. It delivers more efficient cutting technology, with a two-fold increase in cutting volumes compared with its predecessor.

Technology used in the CORI surgical system

The CORI surgical system is powered by Real Intelligence technology, which is designed to improve surgical insight and experience with robotics. It adopts software, smart tools and data for better care management and patient outcomes.

The enhanced robotic software solutions offer image-free smart mapping and allow surgeons to measure, plan and conduct a knee surgery customised to the patient’s specific anatomy by the real-time characterisation of the patient’s bone and cartilage.

The CORI system’s advanced tracking system (ATRACSYS) is designed specifically for robotic surgery and offers a 458% faster refresh rate compared with NAVIO.

The system incorporates RI.KNEE Robotics software, which is designed to enhance surgeons’ workflow to increase productivity and usability while reducing the learning curve.

When used in combination with intuitive software, the portable robotic solution assists in correctly sizing and positioning the components, as well as optimising ligament balance.

Benefits of Smith+Nephew’s Cori surgical system

The CORI surgical system is claimed to be one of the most compact, portable and cost-effective robotic systems on the market today.

The system requires a very short setup time and can be transferred from theatre to theatre to enhance patient flow across surgical units. It also optimises patients’ experience, with significantly improved patient-reported outcome measures (PROMs), shorter hospital stay durations and earlier returns to an active lifestyle.

The use of image-free smart mapping to create patient-specific 3D models of the anatomy in surgery reduces workflow stages by 40% compared to NAVIO. It also reduces the time, expenses and radiation exposure associated with preoperative computerised tomography (CT) imaging.

CORI allows each patient to undergo a knee replacement that is shape-matched and aligned to their anatomy. In addition, it was among the first devices to position the surgeon at the centre of the digital operating room, allowing surgeons to access the benefits of robotic surgery while maintaining complete decision-making authority at every stage of the procedure.

The solution improves surgical workflow, with a 72% reduced requirement for data point collection with automatic landmark capture. It offers a 2.5 times greater data point collection area, with rapid surface model generation, compared with its predecessor.

In addition, the CORI surgical system offers a wide range of compatible total and partial knee arthroplasty implants.

Marketing commentary on Smith+Nephew

Based in Hull, UK, Smith+Nephew is a portfolio medical technology company established in 1856. The company currently employs 18,000 people and operates in more than 100 countries worldwide.

Smith+Nephew envisions the Real Intelligence ecosystem as a game-changer. The comprehensive suite of pre, intra and post-operative treatments that operate together can enhance surgical procedures in the orthopaedic space.

Other Real Intelligence platforms include RI.KNEE NAVIGATION, RI.HIP NAVIGATION, ARIA and RI.INSIGHTS.

Smith+Nephew is also developing an innovative ligament tensioning device for robotic-assisted surgery to help stabilise the knee during total knee arthroplasty (TKA) surgeries.
