Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally invasive surgery training methods either rely on physical objects, which are limited in simulating complex anatomy and safety, or virtual reality, which lacks the tactile experience needed for proficiency development.
Innovation Solution
A biaxial controller and camera system that combines virtual reality with physical training, utilizing sensors and a trocar to simulate the insertion and rotation of minimally invasive surgery tools, allowing for precise measurement and feedback, and a camera with adjustable focus and sensors for enhanced visualization, integrated into a training system that uses a worktable with multiple tool sockets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical training objects are used, then tactile experience and manual skill development are improved, but anatomical complexity and safety are limited
Solution Approach 1:
The patent combines physical training objects with virtual reality technology to create a hybrid training system. The physical controller provides tactile feedback for manual skill development, while the virtual reality component displays complex anatomical structures and surgical procedures, merging the advantages of both physical and virtual training environments.
Solution Approach 2:
The patent introduces a camera and display system as an intermediary between the physical training object and the trainee. This intermediary provides visual feedback showing anatomical structures, surgical instruments, and procedural steps, enabling trainees to learn complex anatomy without requiring complex physical models.
2Loss of information
If virtual reality training is used, then anatomical understanding and procedural guidance are improved, but tactile experience and manual proficiency are reduced
Solution Approach 1:
The patent implements a feedback mechanism where the camera captures images from the physical training object, processes them to highlight anatomical structures and instrument positions, and displays them in real-time. This feedback loop provides continuous anatomical information to guide manual operations without replacing the tactile experience.
Solution Approach 2:
The patent segments the training system into distinct components: a physical controller for manual operations, a camera for capturing visual data, and a display system for presenting anatomical information. This segmentation allows each component to specialize in its strength while working together to provide comprehensive training.
3Adaptability or versatility
If a hybrid training system is created, then comprehensive learning is improved, but device complexity increases
Solution Approach 1:
The patent designs the physical controller to serve multiple functions: it acts as both a mechanical training tool for manual skill development and as a mounting platform for the camera system. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while maintaining training versatility.
