Bone Plate Drill Guide for Accurate Joint Fusion Screw Alignment

The drill guide is designed to fit over the guide wire, with the guide hole aligned to the guide wire trajectory. This nesting arrangement allows the drill guide to leverage the already-positioned guide wire for precise screw placement without requiring a completely separate positioning system, thereby improving precision while limiting the increase in overall device complexity.

The drill guide serves as an intermediary tool between the guide wire and the compression screw. It provides a guided pathway that ensures the screw follows the correct trajectory defined by the guide wire, achieving precise screw placement without directly complex positioning mechanisms by mediating through the simple guide hole structure.

The guide wire is inserted first to establish the correct trajectory and position before the compression screw is inserted. This preliminary action allows the subsequent screw insertion to be guided accurately, maintaining both operation speed and reliability by pre-defining the insertion path.

The drill guide acts as an intermediary that maintains the relationship between the guide wire and compression screw during insertion. It ensures the screw follows the guide wire's trajectory without requiring complex real-time adjustment mechanisms, thus preserving both speed and reliability.

The drill guide serves as an intermediary that aligns the compression screw with the guide wire trajectory. This simple guiding structure ensures proper screw orientation and depth control without complicating the insertion process, thereby maintaining ease of operation while preventing thread damage and excessive screw head protrusion.

The drill guide replaces complex mechanical alignment systems with a simple geometric constraint - the guide hole aligned to the guide wire. This substitution maintains ease of operation by avoiding complex adjustment mechanisms while effectively preventing harmful effects through proper geometric guidance.
