Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hallux valgus deformities, such as bunions, require surgical correction like the Lapidus procedure, which involves fusing the TMT1 joint, but existing methods lack precise control over bone adjustments during surgery.
Innovation Solution
A surgical system comprising a first tool with adjustable components and fasteners that allow controlled adjustment of bones, enabling distraction, rotation, and compression of joints through threaded fasteners and body components, facilitating precise surgical corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional surgical methods are used for correcting hallux valgus deformities, then surgery can be performed, but precise control over bone adjustments during surgery is lacking
Solution Approach 1:
The surgical tool is divided into multiple body components (first body component, second body component, third body component) that can be independently positioned and adjusted relative to each other. Each body component can be coupled to different bones, allowing precise control of bone adjustments through segmented, modular architecture rather than a single complex rigid structure.
Solution Approach 2:
The tool incorporates adjustable and movable body components that can be dynamically repositioned during surgery. The distance and orientation between body components can be modified to accommodate different anatomical configurations and surgical requirements, enabling precise bone alignment through dynamic adjustment rather than fixed positioning.
2Adaptability or versatility
If a rigid fixed tool is used, then structural stability is maintained, but adaptability to different bone configurations is reduced
Solution Approach 1:
The tool features body components that can be adjusted and repositioned relative to one another, allowing the structure to adapt to different bone configurations and anatomical variations. This dynamic adjustability enables the same tool to accommodate multiple surgical scenarios while maintaining stability through controlled positioning mechanisms.
Solution Approach 2:
The surgical tool is designed with multiple body components and adjustment mechanisms that enable it to perform various functions across different surgical scenarios. The tool can be configured to address different bone deformities and anatomical configurations, providing universal applicability while maintaining structural integrity through its modular design.
3Adaptability or versatility
If multiple separate tools are used for different bone adjustments, then functional versatility is achieved, but device complexity and procedural time increase
Solution Approach 1:
Multiple functional capabilities are integrated into a single surgical tool by combining multiple body components (first, second, and third body components) into one unified device. Each body component can be coupled to different bones and adjusted independently, providing the versatility of multiple separate tools while reducing procedural complexity and the number of instrument changes required during surgery.
Solution Approach 2:
The single surgical tool incorporates multiple body components that can perform different functions simultaneously or sequentially. The tool can be configured to address various bone adjustments, rotations, and alignments in one procedure, eliminating the need for multiple specialized tools and reducing overall system complexity despite maintaining high functional versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise surgical adjustments of bones, allowing for controlled distraction and compression of joints, improving the accuracy and effectiveness of surgical procedures for correcting hallux valgus deformities.
Implementation Method 1
The first threaded fastener includes a first threaded section and a second threaded section. Rotation of the first threaded fastener in a first direction causes the first and second body components to move toward each other in a second direction to compress the joint, and rotation of the first threaded fastener in a third direction causes the first and second body components to move away from each other in a fourth direction to distract the joint.
Data Source
AI summary
A system includes a first tool. The first tool includes a first component, a second component, and at least one fastener for coupling the first component to the second component. The first component is coupled to the second component such that a distance between the first component and the second component in a first direction is adjustable. The first tool is configured to provide a controlled adjustment of a first bone relative to a second bone in a second direction that is different from the first direction.
