Spinal Connector With Offset Iliac Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical treatments for spinal disorders often require multiple components and longer surgical times, increasing patient exposure and complexity, especially when stabilizing the spine with multiple spinal rods.
Innovation Solution
A spinal construct with offset and iliac connectors that allows for the use of multiple spinal rods with a reduced number of components, featuring a closed/closed posted connector with set screws for secure rod placement, and configurations for various rod diameters and orientations, facilitating efficient stabilization with fewer constructs and reduced exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple spinal rods and fasteners are used to stabilize the spine, then stability and fixation strength are improved, but device complexity and surgical time increase
Solution Approach 1:
The connector integrates multiple functions into a single component: it receives multiple spinal rods, provides locking mechanisms for each rod, and connects to the fastener. This merging of functions reduces the total number of separate components needed while maintaining the ability to secure multiple rods with appropriate strength and stability.
Solution Approach 2:
The connector is designed as a universal component that can accommodate multiple spinal rods of different diameters and orientations simultaneously. It provides a standardized interface that works with various rod configurations, eliminating the need for multiple specialized components and reducing overall device complexity while maintaining fixation strength.
2Stability of the object's composition
If multiple fasteners and connectors are used to secure spinal rods, then stability is improved, but surgical time and patient exposure increase
Solution Approach 1:
The connector combines multiple locking mechanisms into a single integrated component that secures multiple spinal rods simultaneously. This eliminates the need for separate fastening operations for each rod, reducing surgical steps and time while maintaining spinal stability through the unified locking system.
Solution Approach 2:
The connector is pre-configured with multiple receptacles and locking mechanisms ready to receive and secure spinal rods. This preliminary preparation allows for efficient assembly during surgery, as the component is already structured to accommodate multiple rods without requiring sequential assembly steps, thereby reducing surgical time while ensuring stability.
3Adaptability or versatility
If multiple separate components are used for spinal rod placement, then adaptability to different rod configurations is improved, but device complexity increases
Solution Approach 1:
The connector is designed as a universal component with multiple receptacles that can accommodate spinal rods of different diameters and orientations. This single multi-functional component replaces what would otherwise require multiple specialized components, maintaining adaptability to various rod configurations while reducing overall device complexity.
Solution Approach 2:
The connector provides adaptability in multiple dimensions by offering receptacles oriented at different angles and positions. This dimensional versatility allows accommodation of various rod configurations without requiring additional components, as the connector itself is designed to handle multi-dimensional placement requirements through its geometric arrangement of receptacles.
