Abstract
Bone anchors and surgical instruments (e.g., bone taps, drivers, etc.) are disclosed herein that include integrated guide tips. 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. For example, a surgical instrument can include a guide projection configured for insertion through a cannulation formed in a bone anchor when the surgical instrument is coupled to the bone anchor. The surgical instrument can also include various mechanisms for adjusting the position of the guide projection relative to the bone anchor. The guide projection can replace the needle, stylet, and guidewire used in typical insertion procedures. The bone anchor can also include integrated tapping features to eliminate the need for a separate bone tap instrument. Thus, in some embodiments, targeting, tapping, and driving the bone anchor can be performed in a single step.
