Surgical 3D View Sequencing With Hygienic Digital Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical planning methods lack effective documentation and sharing of procedural schedules, and there is a limited ability to display and transfer planning information between non-sterile and sterile areas in a surgical environment, compromising hygiene and efficiency.
Innovation Solution
A surgical information system with two processing devices, one in a working area and one in a clean area, allows for the transfer and reproduction of a 3D model and sequence of views, enabling documentation and display of surgical plans without physical transfer, and incorporates features like transparency settings, virtual camera positions, and AI-driven view classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If planning information is transferred physically from working area to clean area using paper or notebooks, then information can be shared, but hygiene standards are compromised
Solution Approach 1:
The system creates a digital copy of the 3D model and planning information, transferring it electronically from the working area to the clean area. This eliminates the need for physical paper or notebooks, maintaining hygiene standards while ensuring complete information transfer. The second processing device in the clean area receives and reproduces the exact same planning data that was created in the working area.
Solution Approach 2:
The patent replaces the mechanical system of physical paper transfer with an electronic data transmission system. The processing devices communicate planning information through digital signals, substituting the manual handling of physical documents with automated electronic transfer, thereby eliminating hygiene contamination risks.
2Loss of information
If surgeon memorizes or writes down planning steps manually, then procedural schedule can be documented, but time consumption and potential for error increase
Solution Approach 1:
The system automatically documents the procedural schedule by capturing the sequence of views and orientations defined in the 3D model. The processing devices store this information systematically, eliminating the need for the surgeon to manually memorize or write down steps. The documentation is generated and maintained automatically by the system itself.
Solution Approach 2:
The system creates a digital record of the procedural schedule that is stored and reproduced by the processing devices. This digital copy replaces manual documentation, ensuring accurate preservation of the planning information without requiring the surgeon's time for writing or memorization.
3Manufacturing precision
If detailed 3D model information is displayed in clean area, then surgical planning accuracy is improved, but device complexity and setup requirements increase
Solution Approach 1:
The processing devices are designed to perform multiple functions: creating 3D models in the working area, storing planning information, transmitting data, and reproducing views in the clean area. This multi-functionality reduces the need for separate specialized devices in each area, managing complexity while maintaining high planning accuracy.
Solution Approach 2:
The first processing device in the working area acts as an intermediary that prepares and transmits the detailed 3D model information to the second processing device in the clean area. This intermediary role allows the complex model creation to occur in the non-sterile area while the clean area device focuses on reproduction and display, simplifying the setup requirements in the sterile environment.
