A design of hardware haptic interface for gastrointestinal endoscopy simulation

Area of Science:

• Medical Simulation
• Robotics and Control Systems
• Human-Computer Interaction

Background:

• Gastrointestinal endoscopy requires extensive practice for skill mastery.
• Current simulations primarily offer visual feedback, lacking realistic tactile sensation.
• Effective haptic feedback is crucial for immersive and effective endoscopic training.

Purpose of the Study:

• To propose a novel, portable haptic interface for gastrointestinal endoscopy simulation.
• To provide realistic 2-Degrees of Freedom (2DOF) force feedback.
• To enhance user sensation and training efficacy in endoscopic procedures.

Main Methods:

• Designed a portable haptic interface with decoupled translational and rotational force feedback mechanisms.
• Integrated a gripping mechanism for controlling the connection to the endoscope.
• Focused on creating realistic force feedback for improved simulation fidelity.

Main Results:

• The proposed interface offers 2DOF force feedback, simulating translational and rotational movements.
• Decoupled mechanisms ensure independent control over different force feedback components.
• The gripping mechanism allows for seamless integration with the endoscope.

Conclusions:

• The novel haptic interface significantly advances gastrointestinal endoscopy simulation.
• Provides realistic force feedback, crucial for developing psychomotor skills.
• Offers a portable solution for enhanced endoscopic training and procedural competency.
