Solution Overview
Problem
Existing anatomical prostheses, particularly breast prostheses, fail to accurately replicate the patient's anatomy due to reliance on standard sizes and colors, leading to psychological and physical discomfort for patients post-mastectomy.
Innovation Solution
A method utilizing three-dimensional scanning, computer-aided design, and 3D printing to create personalized anatomical prostheses by superimposing pre- and post-surgery digital volumetric scans, incorporating skin tone and density data to produce molds or directly printed prostheses that replicate the removed anatomical part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional two-dimensional planning and manual programming are used for prosthesis production, then the process is simpler to implement, but the anatomical precision and individualization of the prosthesis are insufficient
Solution Approach 1:
The patent uses three-dimensional scanning technology to create a digital copy of the patient's anatomy, replacing manual measurement and two-dimensional planning. This digital model serves as an accurate replica that can be manipulated and modified computationally to achieve precise anatomical fit without requiring complex manual programming.
Solution Approach 2:
The patent replaces manual mechanical programming and two-dimensional planning with computer-aided three-dimensional design and virtual reality visualization. This substitution enables more precise anatomical representation and customization while reducing the complexity of manual intervention required in the design process.
2Adaptability or versatility
If conventional methods are used, then the production process is faster and simpler, but the functional optimization and patient-specific customization are limited
Solution Approach 1:
The patent performs three-dimensional scanning and digital modeling as preliminary actions before the actual prosthesis manufacturing. By capturing the patient's anatomy and creating a digital model in advance, the system enables rapid iteration and optimization of the design, leading to faster production while maintaining high patient-specific customization.
Solution Approach 2:
The patent utilizes virtual reality technology to visualize and modify prosthesis parameters in three-dimensional space, allowing for real-time adjustment and optimization. This enables extensive patient-specific customization through interactive parameter modification without significantly increasing production time, as the digital model can be rapidly adjusted before manufacturing.
3Reliability
If manual programming and traditional design approaches are used, then the equipment requirements are fewer, but the functional optimization and anatomical accuracy are insufficient
Solution Approach 1:
The patent employs three-dimensional scanning to create an accurate digital copy of the patient's anatomy, which serves as the foundation for functional optimization. This digital replica allows for precise simulation and testing of prosthesis functionality before manufacturing, improving reliability without requiring excessively complex physical equipment.
Solution Approach 2:
The patent introduces virtual reality technology as an intermediary between the digital model and the physical prosthesis. This intermediary enables functional optimization through virtual simulation and visualization, allowing the system to achieve high reliability in functional performance while managing equipment complexity through software-based solutions rather than purely mechanical systems.

AI summary
The invention relates to a method for producing an anatomical prosthesis from flexible synthetic material by computer-aided three-dimensional design on the basis of a first digital volume reading obtained by three-dimensional digitization performed by three-dimensional surface scanning of an envelope of the volume of a part of the body of a patient before ablation of an anatomical part to be replaced by the anatomical prosthesis, and a second digital volume reading obtained by three-dimensional digitization, performed by the same technique, of the same part of the body of the patient after ablation of the anatomical part to be replaced by the anatomical prosthesis. In the method for producing an anatomical prosthesis, a digital volume representation of an envelope of the volume of the anatomical prosthesis is obtained by superposition of the first and second digital volume readings in order to reproduce an identical envelope of the anatomical part to be replaced by the anatomical prosthesis.
