Surgical 3D Model View Sequences for Clean-Area Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical planning methods lack effective documentation and sharing of procedural plans, particularly in sterile environments, leading to hygiene risks and limited visibility of detailed anatomical structures.
Innovation Solution
A surgical information system with separate processing devices in a working and clean area, enabling the transfer of 3D models and view sequences without physical transfer, allowing for documentation, transparency adjustments, and virtual camera positions, and utilizing AI for view classification and milestone triggers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If physical items (notebooks, paper) are transferred from working area to clean area, then planning information can be documented and shared, but hygiene standards are compromised
Solution Approach 1:
The patent implements a digital copying system where the 3D model and surgical plan are created as virtual copies in the working area, then transmitted as data to the clean area for display. This eliminates the need to physically transfer any items between areas, maintaining hygiene standards while achieving complete documentation and sharing of the surgical plan through digital reproduction.
Solution Approach 2:
The patent replaces the mechanical system of physical document transfer with an electronic data transmission system. The surgical plan is converted into digital format and transmitted via communication interfaces between processing devices in different areas, substituting physical movement with electronic signal transmission to eliminate contamination risks.
2Manufacturing precision
If detailed anatomical structures are displayed in sterile environment, then surgical planning accuracy is improved, but risk of contamination from physical items increases
Solution Approach 1:
The patent creates a virtual copy of the detailed anatomical structures through 3D modeling, allowing surgeons to study and plan with high precision in the clean area without needing physical models or documents. The digital 3D model provides complete anatomical detail while eliminating contamination risks associated with physical items.
3Device complexity
If surgeon memorizes planning steps manually, then no documentation is needed, but information loss and errors increase
Solution Approach 1:
The system automatically captures, stores, and manages the surgical plan information without requiring manual documentation by the surgeon. The processing device autonomously handles the creation, storage, and transmission of the 3D model and surgical sequence, eliminating the need for surgeon memorization while ensuring complete information retention.
Data Source
AI summary
A surgical information system having: a first processing device in a working area configured to: provide and reproduce a 3D model of a body part; receive instructions defining a sequence of views on the 3D model in that every view defines an orientation of the 3D model and the sequence defines a chronological order of the views on the 3D model; store the sequence of views together with the 3D model; and transmit the sequence of views and the 3D model to the second processing device located in the clean area; and a second processing device in a clean area configured to reproduce the sequence of views transmitted by the first processing device on a displaying device.
