Modular Arm Stabilizer with Detachable Wrist Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for supporting an arm during surgical, rehabilitative, or imaging procedures fail to provide adequate stabilization and access to the elbow area, leading to difficulties for surgeons and assistants in performing procedures effectively.
Innovation Solution
A modular arm stabilizer device featuring a stabilizer bar with detachable attachments, including a wrist support attachment and reducer attachment, which allows for adjustable positioning and secure fixation of the arm, enabling better exposure and access to the elbow region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional support structures (pillows, foam pads) are used to support the arm, then the arm is provided with basic support, but the elbow area is not adequately exposed and access for surgeons is difficult
Solution Approach 1:
The arm stabilizer is divided into multiple detachable components including a stabilizer bar, wrist support attachment, and reducer attachment. This segmentation allows each component to be optimized for its specific function while enabling easy adjustment and access to the elbow area during surgical procedures.
Solution Approach 2:
The stabilizer bar includes a movable component that can be adjusted along the length of the bar to dynamically reposition the wrist support and reducer attachment. This dynamic adjustment capability allows optimal positioning for different surgical approaches while maintaining stable arm support.
2Reliability
If the arm is placed on a pillow or support structure on the patient's waist or chest, then the arm is supported, but the extremity is not properly secured in a fixed position
Solution Approach 1:
The device uses separate detachable attachments (wrist support, reducer attachment) that can be independently positioned and secured. This segmentation allows the arm to be firmly stabilized while leaving the elbow area accessible for surgical procedures.
Solution Approach 2:
The stabilizer bar acts as an intermediary structure that transfers and distributes the support force along the arm, providing stable positioning without requiring direct contact with the elbow area, thus maintaining both stability and surgical access.
3Area of stationary object
If conventional support devices are used, then the arm is provided with basic support, but good exposure to the extremity particularly the elbow is not achieved
Solution Approach 1:
By dividing the stabilizer into modular detachable components, the device achieves complex positioning capabilities without creating a single complex structure. Each component remains relatively simple while their combination provides optimal exposure to the elbow area.
Solution Approach 2:
The stabilizer bar with its movable component serves multiple functions: providing stable support, enabling adjustment for different surgical approaches, and facilitating exposure to the elbow area. This multi-functionality reduces the need for additional specialized devices.

AI summary
An arm stabilizer includes a stabilizer bar and one or more modular attachments that can be detachably secured to the stabilizer bar. A wrist support attachment can be secured to the distal end of the stabilizer bar. A reducer attachment can be secured to the stabilizer bar between the wrist support attachment and the proximal end of the stabilizer bar. The reducer attachment can be moved along the length of the stabilizer bar at various angular orientations. In some embodiments stabilizer bar is pivotable about a base to allow the stabilizer bar with attachments to be pivoted away from the patient and repositioned at various points in space during use.
