Arthroscopic Visualization Camera For Single-Handed Scope Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic camera systems require two hands to adjust the direction of view and are cluttered by fiber-optic light guides and tubing, causing unwanted rotation and reduced maneuverability due to added weight and stiffness.
Innovation Solution
A minimally invasive camera, cannula, and scope system that enables single-handed operation with integrated illumination, wireless power, and improved fluid management, eliminating cables and tubes from the operating zone, and incorporating ergonomic features for scope rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fiber-optic light guides are attached to the proximal end of the scope, then illumination is provided, but the space is cluttered and the scope rotates unintentionally due to added weight and stiffness
Solution Approach 1:
The patent removes the fiber-optic light guide from the system and replaces it with an integrated LED light source positioned at the distal end of the scope. This extraction eliminates the heavy proximal connection and associated clutter while maintaining illumination functionality.
Solution Approach 2:
The patent replaces the mechanical fiber-optic light guide system with an electrical LED-based illumination system. This substitution allows for lighter materials, integrated power delivery through the same cable, and eliminates the rotational instability caused by the heavy fiber-optic assembly.
2Adaptability or versatility
If tubing and light guides are connected to the proximal end of the scope, then fluid delivery and illumination are provided, but the operating zone is cluttered and maneuverability is reduced
Solution Approach 1:
The patent merges the fluid delivery tubing and electrical power delivery into a single integrated cable assembly. This consolidation reduces clutter in the operating zone while maintaining both fluid delivery and power supply functions, thereby improving maneuverability without sacrificing versatility.
Solution Approach 2:
The single cable assembly serves multiple functions: delivering fluid through integrated lumens, providing electrical power to the LED light source, and enabling data transmission. This multi-functional design eliminates the need for separate tubing and power connections, reducing clutter while maintaining full functionality.
3Length of moving object
If the scope is made longer to increase working distance, then the distal tip is farther from the hand, but control and maneuverability are reduced
Solution Approach 1:
The patent employs a flexible display technology that allows the distal tip to be positioned closer to the hand while maintaining an extended visual field. The flexible display can be bent or angled to provide optimal viewing geometry without requiring a longer mechanical scope, thereby maintaining control while achieving adequate working distance.
