Integrated Drill Guide for Variable and Zero-Angle Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgeons require a drill guide that can accommodate both zero-degree and variable-angle drilling options, as existing drill guides often necessitate the use of separate devices for each angle, which can be inconvenient and inefficient.
Innovation Solution
A drill guide with a frustoconical body and integrated zero-angle guide, featuring a handle and supports that allow for secure engagement with bone plates, enabling both zero-degree and variable-angle drilling by adjusting the position of the drill bit within defined angular limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate drill guides are used for zero-degree and variable-angle drilling, then each guide can be optimized for its specific function, but the number of devices increases and surgical efficiency decreases
Solution Approach 1:
The patent combines zero-degree drilling guidance and variable-angle drilling guidance into a single integrated drill guide device. The guide body includes both a zero-degree guide opening and a variable-angle guide opening, allowing surgeons to perform both types of drilling with one device, thereby reducing the number of devices needed while maintaining drilling precision
Solution Approach 2:
The drill guide is designed with multi-functional capability to accommodate both zero-degree drilling and variable-angle drilling operations. The guide body incorporates multiple guide openings that enable different drilling angles, making the device universal for various drilling requirements in bone plate fixation procedures
2Adaptability or versatility
If multiple drill guides are carried and used during surgery, then all drilling angle requirements can be met, but procedural time increases and surgical efficiency decreases
Solution Approach 1:
The integrated drill guide provides multiple drilling angle options (zero-degree and variable angles) within a single device, eliminating the need to switch between multiple guides during surgery. This reduces procedural time while maintaining adaptability to various drilling requirements
Solution Approach 2:
The drill guide incorporates movable or adjustable components that allow dynamic switching between different drilling angle configurations. The guide assembly can be repositioned or reconfigured during the procedure to accommodate different drilling needs without requiring device replacement
3Productivity
If a single integrated drill guide is used for both zero-degree and variable-angle drilling, then device portability and surgical efficiency improve, but the structural complexity of the guide increases
Solution Approach 1:
The integrated drill guide is divided into distinct functional modules: a guide body with zero-degree guide opening, a variable-angle guide assembly, and support structures. Each module performs a specific function, and they are combined through mechanical connection, allowing the complex functionality to be organized into manageable segments

AI summary
A drill guide, including: frustoconical body with a first opening at a narrower distal end and second opening at a wider the proximal end; a first support with a first end connected to the frustoconical body and a second end; a zero angle guide with an opening aligned with the first opening and wherein the zero angle guide is connected to the second end of the first support.
