Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical treatments for spinal disorders, such as degenerative disc disease and vertebral misalignments, often fail to provide effective stabilization and alignment, leading to persistent pain and mobility issues.
Innovation Solution
A surgical system comprising a surgical device with a shaft and detectable marker, connectable to surgical instruments, is used under robotic guidance to engage vertebral tissue, allowing precise manipulation and implantation of pedicle screws and vertebral constructs for stabilization and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional surgical instruments are used for spinal implantation, then the surgical procedure can be performed, but the precision of vertebral manipulation and implant placement is insufficient
Solution Approach 1:
The surgical device is divided into distinct segments: a shaft portion for engagement with vertebral tissue, a detectable marker portion for tracking, and a connectable interface for surgical instruments. This segmentation allows each component to perform its specific function optimally while enabling precise robotic control of vertebral manipulation.
Solution Approach 2:
The detectable marker acts as an intermediary between the surgical device and the robotic guidance system. The marker enables the robotic system to detect and track the position and orientation of the surgical device, facilitating precise vertebral manipulation without requiring direct complex sensing capabilities in the surgical instrument itself.
2Manufacturing precision
If robotic guidance is implemented for precise vertebral engagement, then the precision of implantation is improved, but the ease of operation is reduced
Solution Approach 1:
The surgical device includes self-contained components: the shaft with engagement features, the detectable marker for automatic tracking, and the connectable interface for instrument attachment. Once positioned, the device performs its function autonomously under robotic control, reducing the need for continuous manual adjustment and simplifying the overall surgical workflow.
Solution Approach 2:
The surgical device is designed with universal compatibility: the shaft can engage with various vertebral structures, the detectable marker works with different robotic guidance systems, and the connectable interface accommodates multiple surgical instruments. This multi-functionality maintains ease of operation across different surgical scenarios while preserving precision through robotic guidance.
3Loss of information
If detectable markers are added to the surgical device, then the ability to track and manipulate vertebral tissue is enhanced, but the device complexity increases
Solution Approach 1:
The tracking function is extracted from the main surgical device structure and implemented as a separate detectable marker portion. This marker can be a simple radiopaque element or fluorescent marker that provides tracking information without requiring complex electronics or power sources, thus minimizing the addition of complexity while maximizing information availability.
