Surgical Microscope Image Guidance for Tool Insertion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmic surgery guidance systems face limitations in accurately and timely reflecting surgeon's instructions, particularly in detecting the insertion of surgical tools, leading to reduced convenience and accuracy in surgical procedures.
Innovation Solution
An image processing device that includes an image input unit, a display image generation unit, and a processing start unit to superimpose guides on the operative field image and detect surgery start instructions, allowing for high-accuracy and real-time input of surgeon's instructions, such as the insertion of surgical tools, to acquire appropriate surgery start-time images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide is displayed on the operative field image to indicate surgery start instruction, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The display image generation unit processes the operative field image by segmenting it into multiple regions, including a guide region and an operative field region. This segmentation allows the guide to be displayed in a structured manner without overwhelming the surgeon with information, improving ease of operation while managing device complexity through organized image processing.
Solution Approach 2:
The guide displayed on the operative field image acts as an intermediary element that mediates between the surgical tool and the surgeon's intent. It provides visual feedback about the surgery start instruction without requiring direct complex interactions, thereby improving ease of operation while the system manages the complexity internally.
2Productivity
If the system detects surgical tool insertion automatically, then the productivity is improved, but the measurement precision requirement increases
Solution Approach 1:
The processing start unit implements a feedback mechanism where the display image generation unit continuously monitors the operative field image for surgical tool insertion. When the surgical tool enters the guide region, the system provides visual feedback by highlighting or confirming the detection, allowing the surgeon to verify the automatic detection. This feedback loop improves productivity by enabling automatic detection while managing measurement precision requirements through verification.
Solution Approach 2:
The system performs partial detection by focusing on specific regions of interest within the operative field image, particularly the guide region where surgical tool insertion is expected. This partial action approach improves productivity by not requiring analysis of the entire image while maintaining sufficient measurement precision for the critical detection area.
