Illuminated Microsurgical Probe With Nested Aspiration Conduit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microsurgical procedures require separate instruments for aspiration and illumination, which can complicate the removal of debris and visualization at surgical sites, particularly in procedures like neurosurgery and spinal surgery.
Innovation Solution
A microsurgical probe that integrates aspiration and illumination functionality, featuring an optic fiber bundle for illumination and an aspiration conduit with a diffuser to illuminate and clear debris from surgical sites efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate instruments are used for aspiration and illumination, then each instrument can be optimized for its specific function, but the surgical procedure becomes more complex and requires multiple instruments
Solution Approach 1:
The patent combines aspiration and illumination functions into a single integrated microsurgical probe. The illumination fiber optic bundle is positioned within the aspiration conduit, allowing both functions to be performed simultaneously by one instrument rather than requiring separate tools for each function.
Solution Approach 2:
The microsurgical probe is designed to perform multiple functions: aspiration of debris through the aspiration conduit and illumination of the surgical site through the fiber optic bundle. This multi-functional design eliminates the need for multiple specialized instruments while maintaining optimal performance of both functions.
2Reliability
If separate instruments are used for aspiration and illumination, then each function can be performed with dedicated tools, but the surgical procedure requires more steps and time
Solution Approach 1:
By merging aspiration and illumination into one probe, the surgeon can simultaneously clear debris and visualize the surgical site without switching between instruments, reducing procedural steps and improving surgical efficiency.
Solution Approach 2:
The integrated design allows continuous simultaneous operation of both aspiration and illumination functions throughout the surgical procedure, eliminating interruptions that would occur when switching between separate instruments.
3Productivity
If an integrated probe is used for both aspiration and illumination, then surgical efficiency improves, but the device structure becomes more complex
Solution Approach 1:
The illumination fiber optic bundle is nested within the aspiration conduit, with the fiber optic bundle positioned concentrically inside the hollow aspiration conduit. This nested arrangement integrates multiple functions within a compact structure without significantly increasing overall device complexity.
Solution Approach 2:
The use of flexible fiber optic material allows the illumination component to be integrated within the aspiration conduit without rigid structural complications, enabling easy positioning and maintaining a streamlined device design.
