Ultrasonic Fluid Motion Generator for Root Canal Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional root canal procedures face challenges in removing broken instruments from within the tooth without causing further damage or enlarging the canal spaces, as these instruments can cause pain, increase infection risk, and impede thorough cleaning and sealing.
Innovation Solution
A system utilizing a fluid motion generator, which may include a pressure wave generator, to create fluid motion or pressure waves outside the root canal, agitating and dislodging the foreign object without direct contact, allowing for its removal without enlarging the canal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical instruments are used to remove foreign objects from root canals, then the foreign object can be removed, but the canal spaces must be enlarged which damages the tooth structure
Solution Approach 1:
The patent replaces conventional mechanical instruments with an ultrasonic device that generates acoustic energy. The ultrasonic vibrations create fluid motion and pressure waves that dislodge and remove foreign objects without requiring mechanical enlargement of the canal, thus preserving tooth structure while achieving effective removal.
Solution Approach 2:
The ultrasonic device utilizes fluid dynamics by generating pressure waves and fluid motion within the root canal. These hydraulic forces agitate and dislodge foreign objects, allowing removal through fluid pressure rather than mechanical force that would require canal enlargement.
2Reliability
If mechanical instruments are inserted into the root canal to remove foreign objects, then the foreign object can be accessed, but the procedure becomes complex and time-consuming
Solution Approach 1:
By substituting complex mechanical manipulation with ultrasonic vibration, the procedure is simplified. The ultrasonic device automatically generates the necessary forces to dislodge and remove foreign objects without requiring complex mechanical instruments or multiple procedural steps.
Solution Approach 2:
The invention changes the physical parameters of the removal process by using high-frequency vibrations and pressure wave generation. This parameter change transforms a complex mechanical retrieval operation into a simpler ultrasonic dislodgment and fluid-driven removal process.
3Quantity of substance
If conventional irrigation methods are used, then fluid can be supplied to the root canal, but insufficient fluid motion is generated to effectively dislodge foreign objects
Solution Approach 1:
The ultrasonic device generates periodic vibrations at high frequency, creating oscillating fluid motion and pressure waves. This periodic action transforms static or slow-moving irrigation fluid into high-velocity dynamic fluid flow that effectively dislodges foreign objects while maintaining adequate fluid supply.
Solution Approach 2:
The invention changes the fluid dynamics parameters by introducing ultrasonic vibration frequency and pressure wave amplitude. These parameter changes convert ordinary irrigation fluid into a high-energy fluid medium capable of generating sufficient motion velocity to dislodge foreign objects without increasing fluid quantity.
