Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of creating patient-specific 3D printed anatomical models is time-consuming and expensive, and current methods require expertise in multiple fields, while virtual models lack the interactive benefits of physical models, particularly in scenarios where physical models are desired for tool interaction and training.
Innovation Solution
A mixed reality system that combines physical anatomical models with virtual information using a mixed reality display and controller, allowing for spatial registration and interaction between physical and virtual models, enabling manipulation and annotation within both physical and virtual spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 3D printing patient-specific anatomical models is used, then physical model interaction and training benefits are improved, but the process becomes time-consuming and expensive
Solution Approach 1:
The patent creates a virtual copy of the physical anatomical model that can be manipulated and annotated without requiring physical printing. The virtual model serves as a digital replica that maintains all necessary anatomical features while eliminating the time-consuming 3D printing process entirely.
Solution Approach 2:
The patent replaces the mechanical 3D printing system with a virtual reality-based digital modeling system. Instead of using physical materials and printing machinery, the system uses software-generated virtual models that can be created instantly from imaging data.

3Productivity
If virtual models are used instead of 3D printed models, then the creation process becomes faster and cheaper, but the ability to interact with physical objects is lost
Solution Approach 1:
The patent embeds virtual annotations and information within the virtual model structure, allowing multiple levels of detail to be nested. The virtual model can display anatomical structures, planned paths, and device information simultaneously at different levels of detail.
Solution Approach 2:
The virtual model acts as an intermediary between the physical anatomical model and the surgical planning process. It provides a digital representation that can be manipulated, annotated, and used for simulation while maintaining the benefits of physical model interaction through virtual reality visualization.
