SpineGuard showcases robotic applications of DSG technology at CRAS Conference


(Boursier.com) — SpineGuard announces that teams of researchers presented 3 papers at the CRAS conference on April 25-26, 2022, in Naples, Italy, reporting progress in the robotic application of DSG technology.

Three different papers were presented at the CRAS conference… The 1st, presented in plenary session, is the fruit of the collaboration between ISIR, Hôpital Trousseau in Paris and SpineGuard. Entitled “Toward automatic bone breach detection for spine surgery using tissue bio-electrical conductivity sensing”, it presents the results of the first collection of intraoperative tissue DSG electrical conductivity data during pedicle piercings in a series of patients with scoliosis.
The 2nd, presented in the form of a poster and entitled “Automatic bone breach detection for spine surgery based on bio-electrical conductivity sensing: Ex-vivo experimental validation” presents the results of the detection of the bone breach and the automatic stoppage of a vertebral piercing performed by a robot.
The 3rd, also in the form of a poster, entitled “Force control of the KUKA LBR Med without external force sensor” relates to a specific servo-control which allows the robot to optimize the use of DSG to detect the breach, and to follow the movement breathing of the patient during the piercing.

These two posters and the algorithms described are the fruit of the collaboration between SpineGuard and ISIR. This work has benefited, in part, from funding from the Horizon 2020 innovation and research program of the European Community, as part of the FAROS project (Functional Accurate RObotic Surgery) agreement No101016985.

“The acceptance of these articles within the framework of a reference conference is a new validation by the scientific community of the interest and the feasibility of using DSG to improve the functionalities of surgical robots in orthopedics. It also testifies to the richness of our collaboration with ISIR and hospital practitioners, which continues with satisfaction. We are also delighted with the publication of the results of the first collection of tissue electrical conductivity data from a series of patients initiated at the end of 2020 thanks to to DSG Connect. The analysis of this data constitutes great added value, both in the field of robotics to assist surgeons and in that of measuring bone quality to help treat patients during and after surgery.” , comments Stéphane Bette, co-founder and Deputy CEO of SpineGuard.

DSG is based on the measurement of local electrical conductivity of tissues in real time and without X-rays, with a sensor placed at the tip of the drilling tool. Its effectiveness is proven by more than 85,000 surgeries worldwide and 19 scientific publications. Since 2017, SpineGuard has been collaborating with ISIR (Institute of Intelligent Systems and Robotics) of Sorbonne University, CNRS and INSERM, to apply DSG to surgical robots to improve their safety, precision and autonomy.
CRAS (Conference on New Technologies for Computer and Robot Assisted Surgery), created in 2011, has become one of the most recognized scientific conferences in Europe and worldwide in the field of robotic surgery.
