1. A tool for seating a spinal rod in a rod-receiving portion of a spinal implant, the tool comprising:
a body having a proximal end and a distal end, the distal end of the body including a first and second flexible branch for gripping a spinal implant, the flexible branches being spaced-apart a distance to form a first recess, the first recess opening at an end of the distal end of the body and extending proximally from the end; an inserter shaft slidably received within the body, the inserter shaft having a distal end adapted to hold a closure mechanism for the implant, the inserter shaft having a proximal end, a distal end, and a transition zone located between the distal and proximal end, the transition zone having a diameter larger than the proximal end of the shaft; a threaded collar, adapted to couple the body and the inserter shaft, wherein the inserter shaft forces a spinal rod into the rod-receiving portion of the implant; and an outer sleeve mounted about the distal end of the body and movable between a first position and a second position in which the outer sleeve surrounds the branches to inhibit separation of the first and second flexible branches, the outer sleeve including a pair of spaced-apart arms at a distal end of the outer sleeve, the arms of the outer sleeve defining a second recess, the second recess aligning with the first recess of the distal end of the body when the outer sleeve is in the second position to accommodate a spinal rod within the first recess and the second recess. |
