Universal Surgical Driver for Spinal Bone Screw Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical systems for treating spinal disorders require a variety of implants and instruments, leading to increased inventory and complexity in the operating room, particularly when dealing with bone screws without pre-coupled tulip heads, which can complicate the attachment of spinal rod receivers.
Innovation Solution
A surgical instrument featuring a driver with a flexible collet and threaded interface allows for secure engagement and modular implant selection, enabling the use of bone screws without pre-coupled tulip heads, providing a universal connection system that minimizes inventory and facilitates in-situ attachment of spinal rod receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a variety of implants and instruments are used to treat spinal disorders, then the ability to address different surgical needs is improved, but inventory complexity and device complexity increase
Solution Approach 1:
The surgical instrument is designed with a universal interface that can accommodate multiple types of bone screws and spinal rod receivers through a single standardized connection system. The driver member features a universal engagement interface that works with different fastener types, eliminating the need for multiple specialized instruments and reducing inventory complexity while maintaining surgical versatility
2Adaptability or versatility
If bone screws without pre-coupled tulip heads are used, then modular implant selection and inventory reduction are improved, but the difficulty of attaching spinal rod receivers increases
Solution Approach 1:
The surgical instrument acts as an intermediary device that bridges the gap between bone screws without pre-coupled tulip heads and spinal rod receivers. The driver member with its universal engagement interface temporarily mediates the connection, allowing the spinal rod receiver to be attached to the bone screw in a controlled, standardized manner that simplifies the attachment process while maintaining modular flexibility
3Adaptability or versatility
If multiple types of implants are maintained in inventory, then surgical customization options are improved, but loss of time for instrument selection and setup increases
Solution Approach 1:
The universal connection system allows a single standardized instrument to work with multiple types of bone screws and spinal rod receivers. This eliminates the need to select and prepare different specialized instruments for different implant types, reducing setup time while preserving the ability to customize the surgical approach based on patient-specific needs
