1. An insertion tool for use in a spinal surgery, the insertion tool comprising:
an outer shaft extending from a proximal end to a distal end;
an inner shaft extending through a lumen of the outer shaft;
a pair of prongs extending from the distal end of the outer shaft;
a rotatable lever arm pivotably attached to the outer shaft along a pivot axis being operatively connected to the inner shaft, the rotatable lever arm movable between a first predetermined position where the inner shaft is in a released position and a second predetermined position where the inner shaft is in a locked position,
a lock button slidably attached to the outer shaft, the lock button movable from a neutral position holding the lever arm in a locked position to an actuated position where the lever arm is rotatable about the pivot axis,
wherein the pair of prongs extend from the distal end of the outer shaft so that when the pair of prongs are advanced into an implant, the insertion tool grips the implant by moving the rotatable lever arm from the first predetermined position to the second predetermined position.
