• Collaboration with the LIB and ISIR labs of Sorbonne University

Regulatory News:

SpineGuard (FR0011464452 - ALSGD), an innovative company that deploys its DSG® (Dynamic Surgical Guidance) local conductivity sensing technology to secure and streamline the placement of bone implants, today announced that its PhD student engineer Andrés Pérez Velásquez successfully presented his thesis on December 11 in Paris, reporting on the progress with a new ultrasound robot-assisted technology allowing the determination of the entry point and pedicle trajectory from the bony surface of the spine.

Stéphane Bette, Deputy CEO and cofounder of SpineGuard, stated: "After the CFA congress presentation last April, this science thesis presentation is the second validation by the scientific community of the pertinence and feasibility of a new original ultrasound technology, patented by SpineGuard and perfectly complementing our DSG technology. It allows to determine without using X-Rays, the entry point and the drilling direction from the posterior surface of the bone, before the DSG sensor drill bit penetrates bone to perform a drilling secured by the automatic breach detection validated by published papers. These outcomes, fruit of our collaboration with Sorbonne University, demonstrate our continued willingness to innovate, and the next step is to search for an industry partner to exploit them."
