A Model with Feedback Mechanism for Learning Hand-Eye Coordination: A Pilot Study

Area of Science:

• Neurosurgery
• Medical Education
• Biomedical Engineering

Background:

• Neuroendoscopic skills practice is essential for surgeons.
• Current synthetic models are expensive or lack feedback.
• Effective training tools are needed for neurosurgery.

Purpose of the Study:

• To develop an affordable neuroendoscopic hand-eye coordination model.
• To incorporate a functional feedback mechanism into the model.
• To facilitate basic skill acquisition in neurosurgery trainees.

Main Methods:

• A clay utensil housed an electronic circuit with steel pins and an LED/alarm feedback system.
• Two exercises were designed: moving a rubber object and passing copper rings of varying sizes.
• Fifteen neurosurgeons tested the model's efficacy and provided feedback.

Main Results:

• Performance varied across exercises, with some surgeons needing multiple attempts.
• Success rates for passing copper rings decreased with smaller diameters.
• Training time significantly reduced with repeated attempts, indicating learning.

Conclusions:

• The developed model provides valuable feedback for neuroendoscopic hand-eye coordination training.
• It serves as a cost-effective alternative for surgical skill development.
• The model aids both trainees and examiners in assessing fundamental skills.
