Abstract
A polyaxial driver system for inserting and setting the angular orientation of an implant includes an elongated component and a distal component. The elongated component extends along a main axis and includes an elongated tubular sheath and an elongated shaft disposed within the tubular sheath. The distal component is pivotally connected to a distal end of the elongated shaft and includes a tubular body extending along the main axis and a spherical head dimensioned to fit and move freely within the tubular body. A proximal end of the elongated shaft includes a first set of outer threads and a proximal end of the elongated tubular sheath includes inner threads shaped and dimensioned to engage the first set of outer threads of the elongated shaft. Rotating the elongated tubular sheath clockwise or counter-clockwise moves the elongated shaft forward or backward along the main axis, respectively.
