Patent number: 10251653Abstract: 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: October 13, 2016Date of Patent: April 9, 2019Assignee: ORTHOSOFT INC.Inventors: Louis-Philippe Amiot, Alain Richard, Yannick Boutin, Joel Zuhars, Yonik Breton, Karine Duval, Herbert Andre Jansen, Benoit Pelletier, Catherine Proulx, Myriam Valin
