Snap-On Adjustable Implant Drill Stop for Surgical Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical dental implant drilling processes are complex, prone to errors, and pose safety risks due to the intricate exchange of drill bits and stops, requiring precision and potentially causing nerve damage or sinus perforations, while patient-specific guides are costly and time-consuming.
Innovation Solution
A snap-on adjustable dental surgical drilling stop device with color-coded snap-on stops that can be easily attached and detached without removing the drill bit, providing a built-in guide for precise depth control and reducing the need for multiple drill stops, allowing for efficient and safe drilling without the need for patient-specific guides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional drill stops and drill bits are manually exchanged for each drilling stage, then drilling depth and diameter precision can be controlled, but the surgical process becomes complex and time-consuming with high risk of error
Solution Approach 1:
The surgical drill device integrates multiple functions into a single system: the handpiece contains both the drill bit holder and the depth stop mechanism, allowing depth control without separate stop collars. The device can accommodate multiple drill bits of different diameters while maintaining consistent depth control through a universal depth adjustment mechanism, eliminating the need to exchange both drill bits and stops for each drilling stage.
Solution Approach 2:
The patent combines the drill bit holder and depth stop into a single integrated handpiece assembly. The depth stop is built into the handpiece structure rather than being a separate component, merging the functions of drill bit retention and depth limitation into one unified device, thereby simplifying the overall system and reducing the number of components to manage.
2Manufacturing precision
If multiple drill bits and stops are exchanged step-wise for expanding the drill hole, then precise diameter control is achieved, but surgery time increases significantly
Solution Approach 1:
The depth stop mechanism is designed to be dynamically adjustable during the surgical procedure. The surgeon can modify the depth setting on the fly without disassembling the handpiece or changing components, allowing rapid adaptation between different drilling stages while maintaining precise depth control throughout the hole expansion process.
Solution Approach 2:
The handpiece is pre-configured with a depth stop mechanism that can be set before each drilling operation. The surgeon prepares the appropriate drill bit and pre-sets the depth limit, then performs the drilling in a single continuous action without intermediate adjustments or component changes, thereby reducing total surgery time while maintaining precision.
3Measurement precision
If patient-specific surgical guides are used to minimize site offset error, then drilling accuracy is improved, but cost and preparation time increase
Solution Approach 1:
The surgical drill handpiece incorporates self-aligning features and built-in depth stop mechanisms that automatically maintain proper drilling parameters without requiring external patient-specific guides. The device itself provides the guidance and depth control functions, eliminating the need for separate, complex guide systems while maintaining high drilling accuracy.
