Publication number: 20220409214Abstract: A drill bit (20, 420, 520, 620, 720, 820, 920, 1020) is provided that includes a connector (32, 232, 532, 632, 732, 832, 932, 1032), which includes a shank (34), configured to receive torque; a proximal electrically-conductive coupler (36, 436, 536, 636, 736, 836, 936, 1036), which is disposed at a distal end (28) of the shank (34), rotationally fixed with respect to the shank (34); and a distal electrically-conductive coupler (38, 238, 438, 538, 838, 738, 838, 938, 1038). The distal electrically-conductive coupler is rotationally fixed with respect to the proximal electrically-conductive coupler, electrically isolated from the proximal electrically-conductive coupler, and shaped so as to define a distal-electrically-conductive external contact surface (62, 862, 962, 1062). The drill bit further includes a drill shaft (30, 130, 230, 330, 430, 830) including an electrically-conductive outer electrode (44) and an electrically-conductive inner electrode (46, 146, 246, 346, 846).Type: ApplicationFiled: December 2, 2020Publication date: December 29, 2022Applicants: CONFIDENT ABC LTD., SPINEGUARD S.A.Inventors: Adi LORIAN, Noa BARER, Roy ZILBERMAN, Ofer PAZ, Anbarasan DURAISAMY, Ulrich SCHRAUDOLPH, Olivier FREZAL

Patent number: 11344372Abstract: Systems, instruments, and methods are provided verifying that a robotic surgery is being performed in accordance with a surgical plan, wherein a surgical tool having a sensor outputs a data signal that enables the trajectory of the surgical tool to be displayed as an overlay on an image of an anatomical portion of a patient and a visual or audible signal that confirms the surgical tool is penetrating the anatomical portion in accordance with the surgical plan and/or that issues an alert indicating that the surgical tool is not being inserted into the anatomical portion according to the surgical plan.Type: GrantFiled: May 28, 2021Date of Patent: May 31, 2022Assignees: SpineGuard Vincennes, Sorbonne Universite, INSERM (Institute National de la Sante et de la Recherche, Centre National de la Recherche Scientifique—CNRSInventors: Maurice Bourlion, Olivier Frezal, Guillaume Morel, Stephane Bette, Thibault Chandanson, Florian Richer, Valentin Kerspern

Patent number: 11291381Abstract: A medical system including a body; a first electrode; a second electrode; an electric generator; and a processing device suitable for determining an electrical characteristic that represents the capacity of the tissue of an anatomical structure between first and second contact surfaces of the first and second electrodes to conduct the electric current, and for emitting a warning signal corresponding to the determined electrical characteristic, the warning signal being intermittent. The processing device is suitable for detecting a variation in the electrical characteristic and for varying at least one variable parameter of the warning signal after a time delay, in accordance with the variation in the electrical characteristic, has elapsed.Type: GrantFiled: April 6, 2016Date of Patent: April 5, 2022Assignee: SPINEGUARDInventors: Maurice Bourlion, Ciaran Bolger, Olivier Frezal, Stéphane Bette

Publication number: 20090216237Abstract: The invention concerns an instrument for moving a vertebra (1) relative to another (2) comprising: a stem (3) consisting of a substantially horizontal crosspicce (5) and a first arm (4) whereof the lower end (15) has means (24) to be anchored to a first vertebra (2); and a second arm (6) whereof the lower end (10) has means (25) for being anchored to a second vertebra (1), and one upper end has a means (7) for actuating in translation said second arm (6) along a direction substantially perpendicular to the crosspiece (5), said actuating means being associated with the crosspiece (5). The second arm (6) is deformable along at least one degree of freedom between the lower end (10) of the second arm (6) and its actuating means (7).Type: ApplicationFiled: June 30, 2006Publication date: August 27, 2009Applicant: SPINEVISIONInventors: Olivier Frezal, Dominique Petit, Stéphane Bette
