Segmented Osteotomy Cut Guide Frame with Aligner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical cut guides for osteotomy procedures are difficult to align properly, restrict visibility and access to the osteotomy site, and often require multiple installations and removals, leading to increased surgical time and potential bone damage.
Innovation Solution
A surgical system comprising a frame with sections that define a window, allowing for alignment with two bones and providing surgical access to the target joint. The system includes a cut guide with a head that fits within the window and an aligner with a high friction grip and shim for precise alignment and bone positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional cut guide is used for osteotomy, then cutting guidance is provided, but alignment difficulty increases and surgical access is restricted
Solution Approach 1:
The surgical system is divided into multiple independent sections (first section, second section, third section, fourth section) that can be separately aligned with different bones. Each section can be independently positioned and secured, allowing for modular alignment without requiring the entire guide to be perfectly positioned at once.
Solution Approach 2:
An aligner component acts as an intermediary tool to facilitate the alignment of the frame sections with the bones. The aligner includes alignment features that interface with both the frame and the bone, making the alignment process easier and more precise.
2Manufacturing precision
If a traditional cut guide is used for osteotomy, then cutting guidance is provided, but surgical visibility and access to the osteotomy site are restricted
Solution Approach 1:
The frame is segmented into multiple sections with spaces between them, creating openings that provide surgical access to the osteotomy site. These segmented sections allow surgeons to reach the target area while the frame remains in place for guidance.
Solution Approach 2:
The frame sections are arranged in a spatial configuration that creates three-dimensional access pathways. The sections are positioned to allow surgical instruments to approach the osteotomy site from multiple angles and directions, improving access without compromising guidance precision.
3Adaptability or versatility
If traditional cut guides require multiple installations and removals, then adaptability to different surgical needs is achieved, but surgical time increases and bone damage risk increases
Solution Approach 1:
The frame sections and cut guides are designed to be adjustable and reconfigurable during the surgical procedure. The attachment mechanisms allow sections to be repositioned and resecured without complete removal, enabling adaptive surgical planning while minimizing repeated installations and removals.
Solution Approach 2:
The frame sections can be configured to work with different cut guides and alignment tools, providing universal applicability for various osteotomy requirements. The standardized attachment mechanisms allow different components to be integrated into the same frame structure, reducing the need for multiple specialized devices.
4Manufacturing precision
If traditional cut guides are used, then cutting guidance is provided, but the amount of bone removal is fixed and may not be ideal for specific patients
Solution Approach 1:
The cut guide configuration is made adjustable to accommodate different bone removal requirements. The depth and orientation of cutting guides can be modified based on patient-specific anatomy and surgical needs, allowing customization of bone removal amount while maintaining cutting precision.
Solution Approach 2:
Different sections of the frame and cut guides can be configured with different properties to address local surgical requirements. The attachment mechanisms and guide geometries can be varied in different locations to achieve patient-specific bone removal patterns while maintaining overall system precision.
