Cantilever Surgery Table for Multi-Angle Intraoperative Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical support systems are inflexible and require patients to be moved between different equipment for imaging and surgical procedures, limiting the ability to perform both surgery and medical image scanning at a single location with multiple scanning options.
Innovation Solution
A radiolucent spinal surgery table with cantilever construction that allows for motion in three degrees of freedom (roll, pitch, and yaw) and is compatible with imaging techniques like MRI, CT, or fluoroscopy, with imaging devices that can move over the table for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed imaging equipment is used, then imaging stability is improved, but device flexibility and adaptability deteriorate
Solution Approach 1:
Instead of moving the patient to fixed imaging equipment, the patent inverts the approach by making the imaging equipment movable relative to the patient. The C-arm imaging device can be positioned and moved over the surgical table, allowing stable imaging to be achieved while maintaining patient stability on the surgical table.
Solution Approach 2:
The patent introduces dynamic capabilities to the imaging system through the movable C-arm device that can be repositioned along tracks or rails above the surgical table. This dynamic positioning allows the imaging equipment to adapt to different surgical positions and angles while maintaining imaging stability during actual scanning.
2Adaptability or versatility
If patient is moved between different support systems, then imaging and surgery can be performed, but procedural complexity increases
Solution Approach 1:
The patent combines surgical and imaging capabilities into a single integrated system. The surgical table with motion control and the C-arm imaging device work together in one location, eliminating the need to transfer patients between separate imaging and surgical equipment, thereby reducing procedural complexity.
Solution Approach 2:
The surgical table is designed with multi-functional capabilities including motion control in multiple degrees of freedom and compatibility with various imaging modalities. This universal design allows the same platform to support both surgical procedures and imaging operations without requiring separate specialized equipment.
3Measurement precision
If fixed imaging equipment is used, then imaging precision is improved, but patient repositioning flexibility deteriorates
Solution Approach 1:
The patent inverts the traditional approach by keeping the patient stationary on the surgical table and moving the imaging equipment instead. This allows precise imaging to be obtained while maintaining patient repositioning flexibility through the table's motion control capabilities.
Solution Approach 2:
The system employs dynamic positioning of the C-arm imaging device that can be moved to different locations and angles above the patient. This dynamic capability allows the imaging equipment to adapt to various surgical positions while maintaining imaging precision, and the surgical table can independently reposition the patient when needed.
4Adaptability or versatility
If multiple imaging devices are provided, then scanning options increase, but device complexity and space requirements increase
Solution Approach 1:
The patent uses a single C-arm imaging device with dynamic positioning capabilities that can be moved to different locations and configured for different imaging modalities. This dynamic approach provides multiple scanning options without requiring multiple fixed imaging devices, thereby reducing system complexity and space requirements.
Solution Approach 2:
The C-arm imaging device is designed as a universal platform that can perform multiple imaging functions and modalities. This multi-functional design provides diverse scanning options while avoiding the complexity of having separate specialized imaging devices for each modality.

AI summary
An system for supporting a patient during a medical procedure including a pedestal supported from a base surface; a ring structure mounted over the pedestal, the ring structure includes inner and outer ring members that are arranged for relative rotation therebetween. An elongated support platform, upon which the patient is supported, is also provided, as well as a bar member for mounting one end of the support platform to the inner ring of the ring structure while the opposite end of the support platform is free so as to be disposed in a cantilever manner from the ring structure. The roll of the support platform is controlled by rotating the inner ring relative to the outer ring, the pitch of the support platform by pivoting the bar member relative to the inner ring, and the yaw of the support platform by rotating the ring structure relative to the pedestal.
