Adjustable Wrist Traction Tower and Scale for Patient Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traction towers are limited in their ability to accommodate a wide variety of individual patient sizes during orthopedic medical procedures, such as wrist arthroscopy, affecting the adjustability and flexibility needed for proper patient positioning.
Innovation Solution
A wrist traction tower system with movable and adjustable components, including a first and second tower that can slide, telescope, and rotate, allowing for customizable sizing to fit various patient arm lengths and sizes, along with a traction tower scale for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional traction towers are used, then the structure is simple and stable, but the adaptability to different patient sizes is limited
Solution Approach 1:
The traction tower is divided into multiple telescopic segments that can move relative to each other, allowing the overall height and configuration to be adjusted for different patient sizes while maintaining structural stability through modular design
Solution Approach 2:
The tower incorporates movable components including telescopic sections and rotatable joints that enable dynamic adjustment of the device configuration to accommodate various patient anatomies and surgical requirements
2Adaptability or versatility
If the tower components are made movable and adjustable, then the adaptability improves, but the device complexity increases
Solution Approach 1:
Telescopic sections are nested within each other, with inner tubes sliding within outer tubes, allowing compact storage when not in use and easy adjustment when needed, reducing the visual and functional complexity despite multiple adjustment capabilities
Solution Approach 2:
The movable components serve multiple functions: telescopic sections adjust height, rotatable joints position the arm assembly, and the same structures provide stability during surgery, reducing the need for separate specialized components

AI summary
A traction tower assembly and traction tower scale. The traction tower assembly includes a tower assembly including a first tower having a first side surface and a second tower having a second side surface positioned adjacent to the first side surface, wherein the second tower is movable with respect to the first tower in a first direction and in a second direction; and an elongated arm assembly attached to and extending from the tower assembly.
