Three scientific papers presented at the Conference on New Technologies for Computer and Robot-Assisted Surgery (CRAS)

PARIS & BOULDER, Colorado, May 04, 2022–(BUSINESS WIRE)–Regulatory news:

SpineGuard (FR0011464452 – ALSGD), an innovative company that deploys its DSG® (Dynamic Surgical Guidance) detection technology to secure and streamline the placement of bone implants, announces that research teams presented three papers at the CRAS conference on 25 apriland and 26and in Naples, Italy. They report the progress made with the robotic application of DSG.

Stéphane Bette, co-founder and deputy managing director of SpineGuard, said: “The acceptance of these papers at an industry-leading conference is further validation by the scientific community of the interest and feasibility of using DSG to improve surgical robots in orthopedics. It also shows the richness of our collaboration with ISIR and hospital practitioners, which continues to our great satisfaction. We are delighted to report the results of the first collection of electrical conductivity data in patient tissues initiated at the end of 2020 thanks to DSG Connect. of these data brings significant added value in the field of robotics to assist surgical procedures, as well as in the measurement of bone quality to help treat patients during and after surgery.”

DSG is based on the local measurement of the electrical conductivity of tissues in real time without X-ray imaging, with a sensor located at the end of the drilling instrument. Its effectiveness has been proven by more than 85,000 surgeries worldwide and 19 scientific publications. In 2017, SpineGuard entered into a collaboration with the ISIR laboratory (Institute of Intelligent Systems and Robotics) of Sorbonne University, the CNRS and INSERM, for the application of DSG to surgical robots and the improvement of their safety, their accuracy and autonomy.

The CRAS (Conference on New Technologies for Computer and Robot Assisted Surgery) founded in 2011 has become one of the most recognized scientific congresses in the field of robot-assisted surgery. Its objectives are to strengthen collaboration between the various research groups to increase efficiency and shorten the development cycle, in a context where many technologies applicable to robotics have not yet made their way to the operating room.

Three papers were presented at the CRAS conference:

1. The first paper, presented in plenary session, is the fruit of the collaboration between Hôpital Trousseau, ISIR and SpineGuard. Entitled “Towards an automatic detection of bone fractures for spinal surgery using the detection of bioelectrical conductivity of tissues”it presents the results of the first intraoperative collection of tissue electrical conductivity data during pedicle drilling in a series of patients with scoliosis.

2. The second communication, presented in the form of a poster and entitled “Automatic detection of bone gaps for spinal surgery based on the detection of bioelectrical conductivity: ex-vivo experimental validation” presents the results of bone breach detection and automatic stoppage of vertebral drilling performed by a robot.

3. The third, also in poster form, entitled “Force control of the KUKA LBR Med without external force sensordescribes a specific control mode that allows the robot to optimize the use of the DSG in order to detect the breach, and to follow the breathing movement cycle during drilling.

These two posters and the algorithms described are the fruits of the collaboration between SpineGuard and ISIR. Part of this work was funded by the European Union’s Horizon 2020 research and innovation program, as part of the FAROS (Functional Accurate RObotic Surgery) project under grant agreement n° 101016985.

About SpineGuard®

Founded in 2009 in France and the United States by Pierre Jérôme and Stéphane Bette, SpineGuard is an innovative company that deploys its proprietary DSG® (Dynamic Surgical Guidance) radiation-free real-time detection technology to secure and streamline the placement of implants. in the skeleton. SpineGuard designs, develops and markets medical devices that have been used in more than 85,000 surgeries worldwide. Nineteen studies published in peer-reviewed scientific journals have demonstrated the multiple benefits that DSG® offers to patients, surgeons, surgical staff and hospitals. Building on these solid fundamentals and several strategic partnerships, SpineGuard has expanded the scope of its DSG® technology into innovative applications such as the “intelligent” pedicle screw, the DSG Connect visualization and registration interface, dental implantology and surgical robotics. DSG® was co-invented by Maurice Bourlion, Ph.D., Ciaran Bolger, MD, Ph.D., and Alain Vanquaethem, biomedical engineer. SpineGuard has engaged in multiple ESG initiatives.
