Modular Pegboard Patient Positioning for Orthopedic Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current modular patient positioning systems for orthopedic surgery lack the flexibility to efficiently position and support different body parts in various anatomical positions, leading to potential joint misalignment and increased surgeon fatigue during procedures.
Innovation Solution
A modular patient positioning system comprising a first pegboard and a second pegboard that can rotate relative to each other, allowing for adjustment in axial rotation, abduction/adduction, elevation/depression, and flexion/extension of body parts, enabling precise positioning of patients for orthopedic surgeries by supporting different body portions in multiple planes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modular patient positioning system uses multiple separate hardware components to position different body parts, then positioning flexibility is improved, but device complexity and hardware quantity increase
Solution Approach 1:
The patent combines multiple positioning functions into a single integrated pegboard structure that can support different body parts simultaneously. The pegboard includes multiple attachment points and can be configured to position the head, torso, and limbs using a unified hardware system rather than separate devices for each body part.
Solution Approach 2:
The pegboard is designed as a universal positioning platform that can accommodate various surgical positions and body parts through standardized attachment mechanisms. The same pegboard structure can be reconfigured for different surgical procedures by adjusting the position and orientation of attached components.
2Manufacturing precision
If the positioning system uses fixed hardware configurations, then device complexity is reduced, but positioning precision and anatomical alignment capability deteriorate
Solution Approach 1:
The positioning system employs dynamic, adjustable components rather than fixed configurations. The pegboard includes movable attachment points and reconfigurable support structures that can be adjusted during surgery to achieve precise anatomical alignment while maintaining surgical workflow efficiency.
3Manufacturing precision
If the positioning system requires extensive hardware adjustments, then positioning accuracy is improved, but surgical time and surgeon fatigue increase
Solution Approach 1:
The pegboard is pre-configured with standardized attachment points and modular components that can be quickly assembled and adjusted. Common surgical positions are pre-planned with corresponding attachment configurations, allowing surgeons to rapidly set up and modify positioning without extensive adjustments during the procedure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system reduces the need for extensive hardware, prevents joint misalignment, and allows for easier access to surgical sites, thereby enhancing surgical efficiency and reducing surgeon fatigue by enabling precise anatomical positioning of body parts during orthopedic procedures.
Implementation Method 1
a second pegboard rotatably coupled to the first pegboard... the first pegboard and second pegboard lying along a common plane in a first configuration and the first pegboard and second pegboard lying along different planes in a second configuration
Implementation Method 2
The mounting structure of the leg positioner allows for adjusting at least one of axial rotation, abduction/adduction, elevation/depression, or flexion/extension of at least a portion of the leg

AI summary
A modular patient positioning system includes: a first pegboard having a first pegboard hole; a second pegboard rotatably coupled to the first pegboard and having a second pegboard hole, the first pegboard and second pegboard lying along a common plane in a first configuration and the first pegboard and second pegboard lying along different planes in a second configuration. A first body portion and a second body portion of a patient's body may be positioned and supported in different planes by having the first pegboard support the first body portion and the second pegboard support the second body portion; and a leg positioner including a mounting structure for mounting the leg positioner on the second pegboard and positioning a leg in a predetermined position relative to the second pegboard. The mounting structure of the leg positioner allows for adjusting axial rotation, abduction/adduction, elevation/depression, and/or flexion/extension of the leg.
