VirtaMed Simulator with Ascension Magnetic Sensors Improves Training in Knee Arthroscopy

Training in knee arthroscopy, a minimally invasive surgical procedure for diagnosing and treating joint problems, is getting a significant boost with the ArthroS™ simulator. Using magnetic sensors made by Ascension Technology, the simulator provides trainees with realistic, hands-on experience in performing arthroscopic knee procedures and managing complications, without risk to patients.

Acquiring basic arthroscopic skills requires many repetitions of the same intervention to develop proficiency. For many years, surgical training could only be done by apprenticeship or by working on animal organs or rubber models.

The ArthroS™ simulator, developed by Zurich-based VirtaMed, combines a lifelike rubber model with virtual reality. Using original endoscopic tools with embedded Ascension sensors, the simulator tracks and records the students' movements, providing feedback as they practice treating a variety of conditions.

"Unlike the robots typically used in surgical simulation, the Ascension tracking system's precise 6-degrees-of-freedom allows us completely free movement of all instruments inside and around a knee model," said Daniel Bachofen, Chief Technology Officer at VirtaMed. "In addition, due to their small size, the sensors require less modification to the original surgical tools than if we were working with robot interfaces."

VirtaMed plans to launch a shoulder module for the ArthroS™ early this year, and will continue adding on to the ArthroS™ platform to develop simulators in future years that provide training for other joints, depending on the need for innovative education.

About arthroscopy

During arthroscopic procedures, small incisions are made in the joint so that a surgeon can insert a narrow tube containing a fiber-optic camera. The procedure is used for both diagnosing and repairing some types of joint damage. Because the procedure is minimally invasive, recovery time is often reduced significantly.

Knee conditions that may be treated with arthroscopy include bone spurs or loose bone fragments, damaged or torn cartilage, inflamed joint linings, joint infections, torn ligaments and tendons and scarring or tissue overgrowth within joints.
