Needle with Drilling and Retentive Sections for Tooth Root Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing tooth fragments, particularly tooth roots and remnants, from the alveolus require complex, multi-step procedures involving cleaning and enlarging the root canal, which are time-consuming, costly, and invasive, leading to prolonged patient discomfort and increased risk of complications.
Innovation Solution
A medical tool with a base and a needle featuring a drilling section and a retentive section that allows for the removal of tooth fragments without prior cleaning or enlargement of the root canal, enabling a single-step extraction using a shape-fit or force-fit connection, facilitated by a mechanical or manual drive, with options for single-part or multi-part configurations and materials like shape memory alloys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-step methods are used to remove tooth fragments, then the tooth fragment can be removed, but the procedure becomes time-consuming and complex
Solution Approach 1:
The patent combines multiple functions (drilling/cleaning and extraction) into a single integrated tool. The needle device includes both a drilling section for cleaning/enlarging the root canal and a retentive section for gripping the tooth fragment, eliminating the need for separate root files, root drills, and extractors that are required in traditional multi-step methods.
Solution Approach 2:
The needle device serves multiple functions: it acts as both a drilling tool for preparing the root canal and an extractor for removing the tooth fragment. The single tool can clean, enlarge, and grip the tooth fragment in sequence without requiring tool changes, making it a universal device for the entire extraction process.
2Reliability
If traditional multi-step procedures are used, then tooth fragment removal is achieved, but the number of surgical steps increases
Solution Approach 1:
The patent merges multiple surgical steps into a single integrated procedure. The needle device performs drilling, cleaning, and extraction in one continuous action, reducing the number of separate surgical steps from multiple (cleaning, enlarging, then extracting with separate tools) to one unified step.
Solution Approach 2:
The needle device is segmented into functional sections (drilling section and retentive section) that work together in sequence. The drilling section first prepares the canal, then the retentive section engages the tooth fragment, allowing multiple functions to be performed by a single multi-functional device rather than multiple separate devices.
3Reliability
If root canal cleaning and enlargement is performed first, then tooth fragment extraction is possible, but patient discomfort increases
Solution Approach 1:
The patent combines the drilling/cleaning function and the extraction function into a single needle device that performs both actions in one insertion. This eliminates the need for separate root files and extractors that require multiple insertions and manipulations, thereby reducing patient discomfort while maintaining effective tooth fragment removal.
Solution Approach 2:
The needle device rapidly performs both drilling and extraction in a single swift motion, minimizing the time the patient experiences discomfort. The integrated design allows the procedure to be completed in one action rather than requiring the patient to endure multiple separate steps including cleaning, enlarging, and then extracting with different tools.
4Reliability
If separate tools are used for cleaning and extraction, then each function is performed adequately, but the invasiveness of the surgical operation increases
Solution Approach 1:
The patent merges the cleaning function and extraction function into a single needle device. This single minimally invasive tool performs both functions that traditionally required separate, more invasive instruments (root files, root drills, and extractors), thereby reducing surgical invasiveness while maintaining adequate performance of each function.
Solution Approach 2:
The needle device is a universal tool that can perform both cleaning/enlarging of the root canal and extraction of the tooth fragment. This multi-functional approach eliminates the need for multiple specialized instruments, reducing the overall invasiveness of the surgical operation while ensuring each function is performed adequately by the appropriate section of the device.
