This study introduces a low-cost system for surgical training, improving adaptation to angled laparoscope views. Junior residents showed greater proficiency, highlighting its value for foundational psychomotor skills.
Area of Science:
- Surgical Education
- Medical Simulation
- Laparoscopic Surgery
Background:
- Adapting to angled laparoscope visual perspectives is vital for laparoscopic surgery proficiency.
- Camera operation, crucial for visual workspace control, is often performed by less experienced surgical team members.
- A novel, low-cost system emulating angled laparoscopes is presented for surgical training.
Purpose of the Study:
- To develop and evaluate a low-cost training system for adapting to 30-degree angled laparoscope visual perspectives.
- To assess the system's efficacy in training basic psychomotor skills for laparoscopic surgery.
- To challenge surgical learners with static and dynamic visual perspectives.
Main Methods:
- A low-cost system was engineered using readily available materials to simulate an angled laparoscope.
- Nine surgical residents performed three distinct tasks assessing spatial adaptation to 30-degree visual perspectives.
- Performance was quantified using time and error rate metrics.
Main Results:
- Nine residents completed 450 task repetitions using the 30-degree angled perspective emulation system.
- Junior residents demonstrated superior proficiency compared to senior residents in task execution.
- The system effectively facilitated spatial adaptation to angled visual fields.
Conclusions:
- The developed system offers a cost-effective method for training junior residents in handling 30-degree angled visual perspectives.
- It provides foundational psychomotor skills development without reliance on expensive laparoscopic towers.
- Advanced surgical skills can be further honed through clinical experience and operating theater practice.
