Segmented Spinal Support Structure with Flexible Cord
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for supporting and correcting spinal curvature are inadequate in providing effective pain relief and structural support for conditions such as scoliosis, fractured discs, and spinal osteo-arthritis, as they lack a comprehensive and flexible solution for enhancing spinal stability and promoting desired curvature.
Innovation Solution
A spinal supporting system comprising a pathway created through the vertebrae, with a series of interconnected segments and a cord providing stiffness, which can be inserted to support the spine, correct curvature, and allow for flexibility, using biocompatible materials and optional cutting tools for pathway creation and fusion-promoting proteins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a supporting structure is inserted through the spine to provide structural support and stability, then spinal stability and curvature correction are improved, but the complexity of the surgical procedure and implant structure increases
Solution Approach 1:
The supporting structure is divided into multiple segments that can be inserted separately through the spine. Each segment can be independently positioned and secured, allowing complex spinal support to be achieved through simpler, modular components rather than a single complex implant.
Solution Approach 2:
The cord is inserted through the interior cavity of the supporting structure segments. This nested configuration allows the cord to be contained within the segments while both work together to provide spinal support, reducing overall structural complexity.
2Strength
If the supporting structure is made rigid to provide strong support, then spinal support effectiveness is improved, but the ability to allow patient movement and flexibility is reduced
Solution Approach 1:
Different parts of the supporting structure have different properties. The segments provide rigid structural support while the cord provides flexibility and tension. This local differentiation of material properties allows the overall structure to be both strong and flexible.
Solution Approach 2:
The supporting structure combines rigid segmental components with a flexible cord element. This composite construction integrates materials with different mechanical properties to achieve both structural strength and movement flexibility simultaneously.
3Ease of operation
If a pathway is created through the vertebrae to insert the supporting structure, then the supporting structure can be properly positioned, but additional surgical steps and potential harm to bone structure are introduced
Solution Approach 1:
The pathway through the vertebrae is created before inserting the supporting structure. This preliminary action allows the pathway to be carefully planned and executed, minimizing bone removal while ensuring proper positioning of the subsequent implant.
