Publication number: 20150342657Abstract: A bone fixation system includes at least one bone fixation member and a bone fixation instrument. The bone fixation member includes a strap and a locking mechanism. The strap can be pulled through the locking mechanism so as to form a loop about a target bone so as to secure first and second bone segments in an approximated, compressed configuration. The bone fixation instrument is configured to apply tension to the loop about the target bone. The fixation instrument includes a tension assembly that is configured to secure a free end of the bone fixation member to the fixation instrument. The tension assembly is further configured to pull the free end so as to increase tension in the loop while the tension in the loop is less than a select tension. The tension assembly is unable to further increase tension in the bone fixation member once the tension in the bone fixation member has reached the select tension.Type: ApplicationFiled: May 5, 2015Publication date: December 3, 2015Inventors: Cyril Voisard, Azagen Mootien, Etienne Crozier, Jean-Luc Thuliez, Nicolas Obliger

Publication number: 20140276893Abstract: An instrument for limiting torque can include a method for limiting torque that is transferred from a handle of the instrument through a torque transfer member to a shaft that extends relative to the handle. The method can include applying a torque to the handle along a direction relative to the shaft. The method can include transmitting the applied torque from the handle through the torque transfer member to the shaft when the applied torque is less than a limited torque value. When the applied torque is greater than the limited torque value, at least one of the torque transfer member and the handle deforms so as to allow the handle to rotate along the direction relative to both the torque transfer member and the shaft.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Inventors: Konrad Schaller, Cyril Voisard
