Patent number: 11812974Abstract: A computer-assisted surgery system for guiding alterations to a bone, comprises a trackable member secured to the bone. The trackable member has a first inertial sensor unit producing orientation-based data. A positioning block is secured to the bone, and is adjustable once the positioning block is secured to the bone to be used to guide tools in altering the bone. The positioning block has a second inertial sensor unit producing orientation-based data. A processing system providing an orientation reference associating the bone to the trackable member comprises a signal interpreter for determining an orientation of the trackable member and of the positioning block. A parameter calculator calculates alteration parameters related to an actual orientation of the positioning block with respect to the bone.Type: GrantFiled: January 17, 2022Date of Patent: November 14, 2023Assignee: ORTHOSOFT ULCInventors: Louis-Philippe Amiot, Alain Richard, Yannick Boutin, Joel Zuhars, Yonik Breton, Karine Duval, Herbert Andre Jansen, Benoit Pelletier, Catherine Proulx, Myriam Valin

Publication number: 20220387111Abstract: A computer-assisted surgery system for obtaining a distance between at least two fixed points relative to a bone comprises a first accelerometer unit located at a first fixed location on the bone, and producing first acceleration data during a movement of the bone. A second accelerometer unit is located at a second fixed location on the bone, and simultaneously producing second acceleration data during the movement. A gyroscope unit is fixed to the bone and simultaneously producing angular rates of change of said movement. A processor unit obtains the acceleration data and the angular rates of change for calculating the distance between the first fixed position and the second fixed position on the bone using a distance value of a distance vector between the accelerometer units. An interface outputs the distance between the first fixed position and the second fixed position relative to the bone. A method for calculating a distance between at least two points on a bone is provided.Type: ApplicationFiled: August 17, 2022Publication date: December 8, 2022Inventors: Bruno FALARDEAU, Catherine PROULX, Herbert Andre JANSEN, Benoit PELLETIER, Jonathan TARDIF
