Radial Access Platform with Radiation Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional trans-radial access platforms do not allow for both right and left radial access from either side of the operating table, and they fail to protect medical staff from ionizing radiation during procedures, making it difficult to perform left radial access procedures safely and effectively.
Innovation Solution
A trans-radial access platform that enables left radial access and right room operation by using a system with a left radial base to stabilize the patient's left arm across the midsagittal plane and a transradiant right radial base to position the right arm away from the midsagittal plane, combined with a radiation reduction barrier made of radiodense material to shield staff from scatter radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional trans-radial access platforms are used, then left radial access can be performed, but staff are exposed to ionizing radiation during procedures
Solution Approach 1:
A radiodense barrier is introduced as an intermediary element between the patient and the staff to block scatter radiation. The barrier is positioned on the procedure table and extends into the path of scatter radiation, creating a physical shield that protects staff without interfering with the medical procedure or imaging capabilities.
2Object-affected harmful factors
If a radiation reduction barrier is added to protect staff, then staff safety improves, but the system complexity increases
Solution Approach 1:
The radiodense barrier serves multiple functions simultaneously: it blocks scatter radiation to protect staff, maintains visibility for medical imaging procedures, and integrates with the existing procedure table structure. This multi-functionality reduces the need for additional separate systems and minimizes overall complexity.
Solution Approach 2:
The barrier is strategically positioned only in the specific region where scatter radiation reaches staff, rather than enclosing the entire procedure area. This localized approach provides necessary protection while minimizing interference with imaging and procedure access, thereby reducing overall system complexity.
3Adaptability or versatility
If the platform supports both right and left radial access, then procedural versatility improves, but the device complexity increases
Solution Approach 1:
The platform employs asymmetric base configurations - a left radial base for left arm access and a right radial base for right arm access - positioned at opposite sides of the procedure table. This asymmetric design allows the platform to accommodate both left and right radial approaches while maintaining a relatively simple overall structure that doesn't require complex reconfiguration.

Implementation Method 1
the radiation reduction barrier having a radiodense material disposed between the patient and an attending staff member to reduce scatter radiation from the patient in a direction of the staff member during a procedure
