Teleoperated System Training Simulator with Virtual Instrument Navigation

Solution Overview

Problem

There is a need for an effective training system for users, particularly surgeons, to operate teleoperated systems used in minimally invasive medical procedures, such as steerable catheters, that provides intuitive control and simulates the graphical user interface and movement of medical instruments through virtual passageways to enhance learning and performance.

Innovation Solution

A simulator system comprising a user control device, a graphical user interface, and training modules stored on a non-transitory computer-readable medium, which allows users to practice navigating virtual medical instruments through virtual passageways, with performance metrics tracked to evaluate and improve their skills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a simulator system is implemented to train users on teleoperated systems, then user learning speed and performance are improved, but device complexity and initial training time requirements increase

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy of the teleoperated system including a virtual medical instrument, virtual passageway, and graphical user interface that replicates the actual system's controls and display. This virtual environment allows users to practice without risking patient safety while maintaining fidelity to the real system's operation

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The simulator enables users to perform preliminary training exercises before actual medical procedures. Users can practice navigating the virtual instrument through complex passageways, managing degrees of freedom, and responding to various scenarios in advance, thereby reducing the learning curve during real procedures

Inventive Principle:
Principle #10Preliminary action

2Reliability

If comprehensive training modules with performance tracking are provided, then training effectiveness and skill assessment are improved, but system complexity and data processing requirements increase

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically tracks user performance metrics including navigation accuracy, time to complete tasks, and control management effectiveness. This feedback is provided in real-time and after training sessions, allowing users to assess their progress and instructors to evaluate competency levels objectively

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The simulator system serves multiple functions: it provides training exercises, tracks performance metrics, evaluates user competency, and prepares users for specific procedural scenarios. This multi-functionality consolidates what would otherwise require separate systems into a single integrated platform

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of time

If realistic simulation environments are created to enhance learning, then user performance improvement is accelerated, but computational resources and system requirements increase

Engineering Contradiction:
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

Solution Approach 1:

The patent replaces physical training models and in-person mentoring with a computer-based virtual simulation system. This substitution allows for more comprehensive and repeatable training scenarios while reducing the need for physical equipment, facility space, and instructor time, thereby improving training efficiency

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
