Patent number: 11259875Abstract: A computer-assisted surgery system comprises a first surgical device with a tracking unit tracked during a surgical procedure and adapted to perform a first function associated to the surgical procedure. A second surgical device is adapted to perform a second function associated to the surgical procedure. A triggered unit is triggered when the first surgical device and the second surgical device reach a predetermined proximity relation. A surgical procedure processing unit tracks the first surgical device. A trigger detector detects a triggering of the triggered unit. A CAS application operates steps of a surgical procedure. A controller commands the CAS application to activate a selected step associated with the second function in the surgical procedure when the trigger detector signals a detection. An interface displays information about the selected step in the surgical procedure.Type: GrantFiled: September 15, 2017Date of Patent: March 1, 2022Assignee: ORTHOSOFT ULCInventors: Yannick Boutin, Jean-Guillaume Abiven, Mathieu Chevrier

Patent number: 11090170Abstract: A method for assisting in positioning the acetabular cup comprises orienting a cup positioning instrument with a cup thereon in an initial reference orientation relative to an acetabulum of a pelvis with the cup forming a joint with the acetabulum, the cup positioning instrument comprising an inertial sensor unit with pre-planned orientation data for a desired cup orientation based on at least one landmark of the pelvis, The cup positioning instrument is rotated to a desired abduction angle as guided by an interface of the cup positioning instrument, based on movements relative to at least one landmark. The cup positioning instrument is rotated to a desired anteversion angle as guided by the interface of the cup positioning instrument, based on movements relative to the at least one landmark. Upon reaching the desired cup orientation as indicated by the interface, the cup is impacted into the acetabulum.Type: GrantFiled: May 2, 2018Date of Patent: August 17, 2021Assignee: ORTHOSOFT ULCInventors: Di Li, Louis-Philippe Amiot, Herbert Andre Jansen, Francois Paradis, Isabelle Robitaille, Bruno Falardeau, Karine Duval, Myriam Valin, Yvan Leone, Yonik Breton, Benoit Pelletier, Mathieu Chevrier, Jerome Casaubon

Publication number: 20210100632Abstract: A method for performing a surgical procedure related to a pelvis of a patient comprises adjusting a length between ends of a digitizer device to a distance between opposite landmarks of the pelvis of the patient. The ends of the digitizer device are applied against the opposite landmarks of the pelvis. An inertial sensor unit of the digitizer device is initialized to set an orientation of the digitizer device relative to a medio-lateral axis of the patient, the medio-lateral axis of the patient being part of a pelvic coordinate system. A tool is navigated within the pelvic coordinate system during a surgical procedure.Type: ApplicationFiled: December 18, 2020Publication date: April 8, 2021Inventors: Francois PARADIS, Joel ZUHARS, Karine DUVAL, Mathieu CHEVRIER, Louis-Philippe AMIOT, Herbert JANSEN, Myriam VALIN, Don DYE, Isabelle ROBITAILLE, Simon FERRON-FORGET, Francois Baudoin

Patent number: 10166083Abstract: A computer-assisted surgery system comprises instruments adapted to be used to perform tasks related to surgery. A reference device is in a fixed relation to a bone. A rotating magnet creates a magnetic field plane, the rotating magnet being connected to one of the instrument and the reference device. A magnetometer on the other of the instrument and the reference device produces signals as a function of at least its orientation relative to the magnetic field plane. A processing unit tracks said orientation of the instrument relative to the bone using said signals from the magnetometer subjected to the magnetic field plane.Type: GrantFiled: August 21, 2017Date of Patent: January 1, 2019Assignee: ORTHOSOFT INC.Inventors: Francois Paradis, Joel Zuhars, Karine Duval, Mathieu Chevrier
