3D Surface Imaging for Intraoperative Surgical Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical marking techniques in aesthetic and reconstructive surgery are often imprecise and based on best estimation, limiting the accuracy of procedures such as autologous fat grafting.
Innovation Solution
The use of 3D surface imaging to process and project accurate surgical maps or models onto the patient during surgery, allowing for precise guidance and decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional 2D photographs and surgical markings are used for surgical planning, then the surgical process can be performed with basic guidance, but the precision and accuracy of surgical markings are insufficient
Solution Approach 1:
The patent transitions from two-dimensional photographs to three-dimensional surface imaging, enabling precise measurement of facial contours, volume deficiencies, and spatial relationships. The 3D imaging system captures multiple dimensions of anatomical data, allowing accurate surgical planning that cannot be achieved with traditional 2D images.
Solution Approach 2:
The system creates a digital 3D copy or virtual model of the patient's anatomy from captured surface images. This virtual replica serves as an accurate reference for surgical planning, replacing the imprecise physical markings and allowing repeated examination and measurement without altering the patient's actual anatomy.
2Manufacturing precision
If 3D surface imaging and virtual modeling are implemented, then surgical planning accuracy is improved, but the complexity of the imaging and processing system increases
Solution Approach 1:
The complex 3D imaging and processing system is divided into separate functional modules: image capture devices, 3D reconstruction software, virtual modeling tools, and projection systems. Each component performs a specific function, making the overall system more manageable and easier to implement while maintaining high precision in surgical planning.
3Loss of information
If preoperative assessment relies on physical examination and 2D photographs, then the surgical process remains simple, but the ability to make accurate surgical decisions is limited
Solution Approach 1:
The system adds a third dimension to anatomical assessment by capturing depth, volume, and spatial relationships that are invisible in 2D photographs. This enables complete characterization of facial anatomy, including subtle contours and volume deficiencies that directly inform surgical decision-making.
Solution Approach 2:
The 3D imaging system provides immediate visual feedback and quantitative measurements during the assessment process. The system can display virtual models, measure volumes, and compare anatomical features in real-time, enabling more informed and accurate surgical decisions compared to traditional assessment methods.
