Modular Arm Stabilizer with T-Rail for Elbow Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical arm stabilizers fail to provide adequate exposure and access to the elbow during procedures, making it difficult for surgeons and assistants to perform surgeries effectively.
Innovation Solution
A modular arm stabilizer system with a base that attaches to the operating table, featuring a T-shaped rail for adjustable support arms, a cuff system with interchangeable foam cuffs, and bicep pads for secure positioning, allowing for full exposure of the elbow and easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pillow or foam pad is used to support the patient's arm, then the arm is provided with basic support, but the elbow is not properly exposed and accessible to the surgeon and assistants
Solution Approach 1:
The support structure is divided into multiple independent components: a base that attaches to the operating table, adjustable support arms with cuffs for wrist positioning, and separate elbow support elements. This segmentation allows each component to be optimized for its specific function while collectively providing full elbow exposure and access without requiring a complex monolithic structure.
Solution Approach 2:
The support structure incorporates adjustable elements including movable support arms, interchangeable foam cuffs of various sizes, and repositionable padding. These dynamic features enable the device to adapt to different patient anatomies and surgical requirements, providing optimal elbow exposure and accessibility while maintaining a relatively simple overall structure.
2Stability of the object's composition
If the arm is placed on a pillow resting on the patient's chest or waist, then the arm is supported, but the extremity is not securely maintained in a fixed position
Solution Approach 1:
The device merges multiple stabilization functions into a single integrated system: the base provides stable attachment to the operating table, support arms secure the forearm and wrist in customizable positions, and elbow support elements maintain the elbow in a stable, exposed position. This combination achieves secure fixed positioning while simultaneously providing excellent surgical access.
3Ease of operation
If prior art devices are used to stabilize the arm, then some support is provided, but good exposure to the elbow and easy access for surgeon and assistants is not achieved
Solution Approach 1:
The support device is designed with universal applicability through interchangeable foam cuffs in multiple sizes, adjustable support arms, and modular components that can accommodate various patient anatomies and surgical procedures. This multi-functionality allows a single device design to provide excellent elbow exposure and access without requiring complex customization or multiple different devices.

AI summary
A device for stabilizing a patient's arm during a surgical procedure including a base configured to fit on an operating table. A support arm has a proximal end attached to the base and a distal end extending away from the base. A cuff is mounted on the distal end of the support arm to support the wrist of a patient. One or more bicep pads are connected to the support arm and are positioned to fit about the bicep of a patient lying on an operating table.
