Patent number: 9433473Abstract: A tool for digitizing a mechanical axis of a tibia using a computer-assisted surgery system is described. The tool includes upper and lower mounting ends interconnected by an alignment rod extending therebetween. The upper mounting end is releasably fastenable to an upper reference point on a tibial plateau and the lower mounting end includes a self-centering malleoli engaging mechanism having opposed caliper arms displaceable in a common plane relative to each other for clamping engagement with the medial and lateral malleoli of the ankle. At least one trackable member is mounted to the alignment rod of the tool and is in communication with the computer assisted surgery system for providing at least orientation information of the alignment rod. The mechanical axis of the tibia is parallel to the alignment rod and extends between the upper and lower reference points when the tool is mounted on the tibia.Type: GrantFiled: September 3, 2013Date of Patent: September 6, 2016Assignee: ORTHOSOFT INC.Inventors: Benoit Pelletier, Karine Duval, Trong Tin Nguyen, Pierre Couture, Louis-Philippe Amiot, Yannick Boutin, Alain Richard, Catherine Proulx

Publication number: 20120220859Abstract: A method tracks a tool with respect to a bone in computer-assisted surgery. A reference tracker with a MEMS unit is secured to the bone. The tracker outputs data relating to its orientation. A tool provided with a MEMS unit and secured to the bone is preset with an initial orientation. The tool outputs tracking data related to orientation of the tool once initialized. A trackable frame of reference relating the bone to the orientation of the tracker is created. The MEMS unit of the tool is initialized. A relation between the initial orientation of the tool and the orientation of the tracker at initialization of the MEMS unit of the tool is recorded. Orientational data of the tool relative to the frame of reference of the bone calculated using the relation is displayed. A computer-assisted surgery system for tracking a tool with respect to a bone after an initialization of a MEMS unit is also described.Type: ApplicationFiled: February 25, 2011Publication date: August 30, 2012Inventors: Louis-Philippe Amiot, Pierre Couture, Catherine Proulx, Trong Tin Nguyen, Myriam Valin

Publication number: 20120029389Abstract: A system tracks an object in computer-assisted surgery. The system comprises a sensor unit secured to the femur. Gyroscopes on the sensor unit produce readings related to orientation data about three axes of rotation. A tracking unit receives the gyroscope readings. An axis calibrator on the tracking unit comprises a calculator for adding at least part of the gyroscope readings for specific movements of the object about a desired axis. An axis normalizer on the tracking unit determines an orientation of the desired axis with respect to the sensor unit from the added gyroscope readings. A tracking processor tracks the desired axis from the gyroscope readings. An interface displays orientation data for the object from a tracking of the desired axis. A method for tracking an object with a gyroscope sensor unit is also provided.Type: ApplicationFiled: July 30, 2010Publication date: February 2, 2012Inventors: Louis-Philippe Amiot, Joel Zuhars, Catherine Proulx, Mynam Valin, Tin Nguyen, Benoit Pelletier, Karine Duval Duval, Alain Richard, Rula Kiblawi, Yannick Boutin
