摘要：
Surgical instruments and methods for delivering bone anchor assemblies into bone are disclosed herein. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. In general, a surgical instrument can include a handle assembly having an elongate shaft extending distally therefrom. The handle assembly can be configured to axially translate a carrier assembly that secures a stylet extending therethrough. Translation of the stylet can be made relative to a distal end of the elongate shaft. The surgical instruments can include various carrier assemblies for positioning the distal end of the stylet relative to the distal end of the elongate shaft based on a length of bone anchor to be installed by the surgical instrument.
