Bunion Resection Guide for Precise Bone Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for correcting bunion deformities in orthopedic surgery face challenges such as lengthy and painful recovery, slow healing, and difficulty in aligning and stabilizing small bones during the resection and realignment process due to lack of repeatable landmarks and precise control over bone movement.
Innovation Solution
A bone plate system with a resection guide that includes a plate and a guide for positioning on the bone, allowing for precise cutting and alignment, and the use of fixation devices to secure the plate to the bone segments, facilitating controlled bone resection and realignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional plates and step-wise approach are used, then the surgery can be performed with standard equipment, but the alignment precision and repeatability are insufficient due to lack of landmarks
Solution Approach 1:
The guide is positioned and secured to the bone before the actual cutting is performed. This preliminary positioning establishes repeatable landmarks and precise orientation for subsequent resection, solving the alignment precision problem while using a straightforward sequential process
Solution Approach 2:
The guide acts as an intermediary device between the surgeon and the bone. It provides physical references (landmarks) and guides for cutting, enabling precise alignment without requiring complex measurement or positioning techniques
2Stability of the object's composition
If bones are sectioned and shifted without integrated guidance, then the procedure follows conventional steps, but the stability and close approximation of bone surfaces are difficult to achieve
Solution Approach 1:
The guide combines multiple functions into a single integrated device: it provides positioning landmarks, guides cutting orientation, and facilitates bone approximation. This merging eliminates the need for separate steps and tools, making the procedure easier while ensuring stability
Solution Approach 2:
The guide structure itself provides the reference framework for the entire procedure. Once positioned, it self-establishes the geometric relationships needed for precise cutting and stable bone approximation without requiring additional measurement or adjustment steps
3Reliability
If cutting is done before joining with plates, then the procedure follows conventional sequence, but repeatable landmarks are unavailable for consistent results
Solution Approach 1:
The guide is positioned and secured to the bone before the actual cutting is performed. This preliminary positioning establishes repeatable landmarks and precise orientation for subsequent resection, solving the alignment precision problem while using a straightforward sequential process
Solution Approach 2:
The guide serves multiple functions: establishing landmarks, guiding cut orientation, and facilitating plate placement. This multi-functionality in a single device maintains surgical efficiency while improving reliability through consistent reference points
