Abstract
An instrument for insertion and positioning of a spinal implant includes an outer member, an inner member, and a first thread. The outer member includes a distal attachment feature configured to engage with the spinal implant, a tubular member, and a proximal housing. The inner member is rotatably disposed within a lumen of the outer member and includes a distal coupling feature for coupling with a proximal end of the spinal implant, an elongated shaft within the tubular member, and a proximal end operably coupled with a handle that rotates relative to the proximal housing. The first thread is disposed on the distal coupling feature and includes a first lead and a first thread pitch greater than a thickness of the proximal end of the spinal implant.
