Origami-Based Haptic Syringe for Local Anesthesia Simulator

Area of Science:

• Biomedical Engineering
• Medical Simulation
• Origami Engineering

Background:

• Haptic feedback and virtual reality (VR) are crucial in medical simulators, but haptics often present cost and size challenges.
• Acquiring proficiency in the inferior alveolar nerve block (IANB) procedure in dentistry is a difficult motor skill due to complex tactile feedback requirements.
• Existing training solutions for IANB are often impractical due to oversimplification or overcomplication.

Purpose of the Study:

• To develop a low-cost, compact, and accurate haptic interface for inferior alveolar nerve block (IANB) local anesthesia training.
• To leverage origami principles for creating a versatile and tunable haptic feedback system.
• To evaluate the performance and usability of the developed haptic syringe.

Main Methods:

• Designed and developed an origami-based haptic syringe interface utilizing the Kresling origami pattern.
• Characterized the mechanical properties and force feedback of the developed interface.
• Conducted a preliminary usability study comparing the haptic syringe to traditional methods for IANB training.

Main Results:

• The origami-based haptic syringe successfully simulated the tactile experience of anesthetic injection.
• The force profile generated by the haptic syringe was perceptually similar to that of a standard Carpule syringe.
• The usability study indicated significant improvements in IANB training simulation effectiveness.

Conclusions:

• The origami-based haptic syringe offers a promising solution for cost-effective and accurate medical simulation, particularly for dental anesthesia training.
• The developed interface demonstrates potential for broader applications in various medical training and simulation scenarios.
• This innovative approach addresses the limitations of current haptic technologies in creating accessible and effective training tools.
