A force sensor improves trainee technique for rigid endoscopy.

Area of Science:

• Surgical Education
• Medical Simulation
• Otolaryngology

Background:

• Rigid endoscopy training presents challenges for surgical trainees.
• Developing technical proficiency requires effective feedback mechanisms.

Purpose of the Study:

• To evaluate a modified manikin's efficacy in enhancing junior surgical trainees' technical skills in rigid endoscopy.
• To assess the impact of quantitative, real-time force feedback on operative technique.

Main Methods:

• A life support manikin was modified with an integrated oral force-sensing pad.
• Junior trainees and senior otolaryngologists performed rigid endoscopy procedures.
• Real-time feedback on applied force was provided to operators during the procedure.

Main Results:

• A significant inverse correlation was observed between operator seniority and applied force (p < 0.0001).
• Junior trainees demonstrated a statistically significant reduction in applied force after five attempts (118 g decrease, p = 0.007).
• Quantitative feedback led to improved force modulation in learning operators.

Conclusions:

• The modified manikin offers a low-cost, safe simulation for practicing high-risk procedures.
• This model enables trainees to refine operative techniques through objective feedback.
• It provides a valuable tool for improving surgical skill acquisition in rigid endoscopy.
