This manual, reusable instrument is typically constructed from high-grade stainless steel. It functions like a forceps, with jaws that securely clamp onto the head of an implanted screw (receiver). Once engaged, the surgeon pivots the instrument. This pivoting action causes a cross-pin or foot on the instrument to press down on the spinal rod, reducing it into the screw head's channel. The ultimate goal is to hold the rod in place so a set screw can be secured, completing the fixation.
