Modular Staged Reality Simulator for Surgical Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical training methods, such as apprenticeship models and virtual reality, lack the ability to provide repetitive and realistic simulations of surgical scenarios, leading to inadequate preparation for medical professionals, particularly in tactile surgical skills and high-stakes situations like thoracic surgery, resulting in high failure rates for surgical board certification exams.
Innovation Solution
A modular staged reality simulator using segmented mannequins with permanent and filler components made from materials like ballistic gelatin and synthetic human tissues, connected via umbilical cables for pneumatic, fluid, and electrical supplies, allowing for realistic and repeatable simulations of surgical procedures, including pulsatile heart and trauma scenarios, with a master-controller managing the simulation and data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional apprenticeship model is used for surgical training, then medical professionals gain real surgical experience, but the training lacks repeatability and control over surgical scenarios presented
Solution Approach 1:
The training system is divided into modular components: a mannequin with replaceable organ modules (heart, lungs, liver, etc.), each containing specific surgical scenarios. This segmentation allows individual modules to be swapped out, providing controlled repetition of specific surgical scenarios while maintaining overall training effectiveness.
Solution Approach 2:
The system uses controllable parameters such as pulsatile motion simulation, fluid flow rates, and organizational responses to create standardized surgical scenarios. By controlling these parameters, the system provides repeatable training conditions while maintaining surgical realism, resolving the contradiction between reliability and adaptability.
2Measurement precision
If virtual reality training is used, then diagnostic and prioritization skills are improved, but tactile surgical skills cannot be practiced
Solution Approach 1:
The system uses synthetic organic tissue materials as an intermediary between virtual reality diagnostics and actual surgical practice. These materials provide realistic tactile feedback and surgical resistance, allowing trainees to practice hands-on surgical skills while the system maintains controlled scenarios for diagnostic assessment.
3Ease of operation
If intact cadavers are used for training, then realistic surgical practice is provided, but the training cannot be repeated and is ethically limited
Solution Approach 1:
The system creates copies of human organs using synthetic materials that replicate the tactile and structural properties of real tissue. These copied organs can be repeatedly used for training without ethical concerns, maintaining surgical realism while enabling unlimited repetition of training scenarios.
Solution Approach 2:
The modular organ modules can be replaced when worn or depleted, allowing continuous training without permanent degradation of training value. Used modules can be recovered, reset, or replaced, ensuring unlimited training repetition while maintaining ethical standards.
4Reliability
If supervised apprenticeship on human patients is used, then real surgical outcomes are achieved, but the failure rate for board certification is high due to limited exposure to diverse scenarios
Solution Approach 1:
The mannequin system is designed with multiple organ modules and configurable scenarios that can simulate various surgical conditions, pathologies, and complications. This universal platform allows trainees to exposure to diverse surgical scenarios in a controlled setting, improving both outcome quality and scenario diversity before board certification.
