Modular Surgical Guide for Interchangeable Spinal Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical treatments for spinal disorders, such as degenerative disc disease and osteoporosis, often require multiple implants and instruments, which can complicate the surgical process and disrupt the sterile field, and existing surgical instruments lack versatility for handling different sizes and types of surgical tools.
Innovation Solution
A modular surgical guide system with interchangeable collets and extenders that can accommodate various surgical instruments, allowing for a single surgery to utilize multiple tools, and a surgical robot-assisted system for precise instrument delivery and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple implants and instruments are used for spinal surgery, then the surgical treatment can address various spinal disorders, but the surgical process becomes complicated and the sterile field is disrupted
Solution Approach 1:
The surgical guide is designed with a universal interface that can accommodate multiple different surgical instruments and implants through a single standardized mounting mechanism. The guide body includes a cavity that can receive various rod holders, bone fasteners, and other spinal instrumentation, allowing one guide structure to serve multiple functions throughout the surgical procedure.
Solution Approach 2:
The patent combines multiple instrument-holding capabilities into a single integrated surgical guide structure. Rather than requiring separate guides for different instruments, the design merges these functions into one guide body with a common mounting interface, reducing the number of separate components and simplifying the surgical workflow.
2Adaptability or versatility
If multiple surgical instruments are delivered during surgery, then various spinal conditions can be treated, but the sterile field is repeatedly disrupted
Solution Approach 1:
The surgical guide provides a universal mounting interface that can securely hold various surgical instruments including rod holders, impactors, and bone fasteners. This allows the surgical team to exchange different instruments without removing the entire guide structure from the patient, thereby maintaining the sterile field throughout the procedure.
Solution Approach 2:
The surgical guide acts as an intermediary structure that remains in place while facilitating the exchange of multiple surgical instruments. By serving as a stable intermediary platform, it allows instrument changes without requiring removal and reinstallation of the guide itself, thus preserving sterility.
3Reliability
If a single surgical guide structure is used, then the sterile field is maintained, but the guide must accommodate various sizes and types of surgical tools
Solution Approach 1:
The guide body includes a standardized cavity and mounting interface designed to accommodate multiple types of surgical instruments. The interface can receive various rod holders, bone fasteners, and other spinal instrumentation through a common attachment mechanism, providing versatility while maintaining a single guide structure.
Solution Approach 2:
The surgical guide is designed with modular components, including a main guide body and interchangeable instrument-holding elements. This segmentation allows different instrument adapters to be attached to the same guide body, enabling accommodation of various tool types without compromising the integrity of the main guide structure.
