Patent number: 9795416Abstract: A bone screw assembly includes an anchor portion and a head portion, such as a rod-receiving portion, movably mounted to the anchor portion to allow for controlled angulation between the anchor portion and the head portion. The anchor portion is pivotable in one or more selected directions about an axis relative to the head portion. A restriction member, which may be a rod seat, prevents the anchor portion from pivoting in one or more different directions about another axis relative to the head portion and/or a spinal fixation element received in the head portion. The restriction member may be inserted in the head portion to control direction that the anchor portion pivots relative to the head portion. The restriction member may also serve as a compression member and/or rod seat for seating a spinal rod coupled to the bone screw assembly.Type: GrantFiled: June 29, 2015Date of Patent: October 24, 2017Assignee: Medos International SárlInventors: Nam T.

Patent number: 9788904Abstract: 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: February 24, 2014Date of Patent: October 17, 2017Assignee: ORTHOSOFT INC.Inventors: Yannick Boutin, Jean-Guillaume Abiven, Mathieu Chevrier
