Interactive Medical Training System with Step Segmentation and Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical training systems lack effective methods to organize training sessions, provide guidance, and offer measurable results, especially for endoscopic and X-ray visualization interventions, making it difficult to assess user performance and identify areas for improvement.
Innovation Solution
A structured training system that divides sessions into manageable parts, allows users to repeat and practice specific steps, provides graphical feedback and guidance, and offers a comprehensive assessment at the end to evaluate performance and identify weaknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medical training systems use actual endoscopic instruments and video displays, then realism and immersion are improved, but the ability to provide structured guidance and measurable assessment results deteriorates
Solution Approach 1:
The training system divides the medical procedure into discrete steps or modules, each with specific learning objectives and assessment criteria. This segmentation allows structured guidance while maintaining realism through actual instruments, enabling supervisors to assess specific competencies rather than overall performance only.
2Ease of operation
If the training system provides comprehensive guidance and assessment, then training quality is improved, but the complexity of the system increases
Solution Approach 1:
The system implements feedback mechanisms where user actions with actual instruments are captured, processed, and presented as assessment results to both users and supervisors. This structured feedback provides comprehensive guidance and measurable outcomes without requiring complex system architecture through standardized data collection and presentation protocols.
3Measurement precision
If the system captures and stores detailed session history for assessment, then measurement precision is improved, but data management complexity increases
Solution Approach 1:
The system creates standardized digital representations or copies of the training session data, capturing user actions, timing, and outcomes in a structured format. These digital copies enable precise measurement and assessment without requiring complex physical data management infrastructure, as the information is stored and processed electronically through standardized protocols.

AI summary
A method for training a user in a medical procedure utilizes an interactive computer system with a virtual representation of at least one organ and at least one instrument. The representation of surface area parts of the virtual organ to be treated are covered with a graphical identification marker. The computer system includes a table stored in memory comprising situations arising within the medical procedure predefined through positions of the instrument(s), positions of the organ(s), the logical sequence of steps to be executed within the medical procedure, different aspect values for the graphical identification markers and assessment values for the situation. Upon interaction of the user with the organ and the instrument, graphical identification markers change their aspect according to the stored value in the table for the predefined situation and the corresponding assessment value is stored in a history log table within the computer system.
