Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical techniques lack effective devices for securely clamping and stabilizing spinous processes during spinal procedures, such as preserving or removing posterior spinous ligaments, which can lead to instability and complications.
Innovation Solution
A spinous process device comprising plates with connector devices and locking mechanisms that allow angular displacement and secure positioning between spinous processes, utilizing screws, bolts, pins, or springs to ensure stable clamping and accommodate varying anatomical configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid clamping devices are used to secure spinous processes, then stability is improved, but adaptability to varying anatomical configurations deteriorates
Solution Approach 1:
The clamping device incorporates adjustable components including telescopic arms with locking mechanisms that allow dynamic adjustment of the clamping distance, and rotatable connectors that enable angular displacement to match varying anatomical configurations of spinous processes while maintaining stable fixation
2Ease of manufacture
If fixed-distance clamping devices are used, then manufacturing simplicity is improved, but adaptability to different anatomical configurations deteriorates
Solution Approach 1:
The clamping device is divided into modular segments including adjustable arms, rotatable connectors, and locking mechanisms that can be independently positioned, allowing the device to accommodate different anatomical configurations while maintaining a relatively simple overall structure
Solution Approach 2:
The device incorporates dynamic adjustment capabilities through telescopic arms and rotatable connectors that allow the clamping distance and angle to be adjusted post-manufacturing to match varying anatomical configurations
3Adaptability or versatility
If complex locking mechanisms are added to allow angular displacement, then adaptability is improved, but device complexity increases
Solution Approach 1:
The device uses rotatable connectors with locking mechanisms that allow angular displacement between clamping arms to adapt to varying anatomical configurations, providing dynamic adjustability without excessive complexity through straightforward mechanical locking
4Adaptability or versatility
If multiple adjustment mechanisms are incorporated, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The device incorporates adjustable components including telescopic arms and rotatable connectors that can be adjusted during surgery to match the patient's anatomy, providing necessary adaptability while maintaining reasonable ease of operation through straightforward mechanical adjustments
