20140277203 | TORQUE MULTIPLIER, LIMITER, AND COUNTER-TORQUE COMBINATIONS AND METHODS - A drive train includes a torque multiplier assembly and a torque limiter device. An output of the torque multiplying assembly is drivingly coupled to an input of the torque limiter device. An input of the drive train is configured to be driven by a driver handle and an output of the drive train is configured to rotate a driver. A counter-torque connector that is configured to engage a spinal fixation construct is coupled to a counter-torque handle to prevent rotation of the spinal fixation construct. A coupling between a component of the torque multiplier assembly and the counter-torque handle prevents rotation of the component. Torque input by the single user through the driving handle is simultaneously multiplied by the torque multiplier assembly and limited by the torque limiter device, while the single user simultaneously prevents the spinal fixation construct from rotating through the counter-torque handle. | 2014-09-18 |
20140277204 | METHOD AND APPARATUS FOR MINIMALLY INVASIVE INSERTION OF INTERVERTEBRAL IMPLANTS - A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. An access cannula may be introduced over the first dilator tube. A drill may be inserted through the access cannula and used to perform a foraminoplasty. Surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant. | 2014-09-18 |
