INTRODUCTION: Laparoscopic camera navigation is a key skill for surgical trainees, as it directly affects visualization during procedures. Camera navigation is one of the first skills learned by medical students and interns during laparoscopic cases. Currently there is no simulation trainer that exists for learners to practice controlling the laparoscope. Existing models either used a fixed camera or one without the proper viewing angles or adjustments to simulate true camera navigation. Previous simulation-based training curricula focused on laparoscopic instrument training rather than camera movement. To address this, we developed a cost-effective laparoscopic camera navigator trainer that replicates the challenges of real laparoscope use, improving trainees’ ability to manage camera control and maintain proper orientation.
METHODS AND PROCEDURES: Using an iterative process, a model was developed matching the dimensions of a standard laparoscope and integrated with rotating lens attachment. A borescope was used to replicate the visual experience, allowing controlled movements simulating actual laparoscope use. The trainer includes a beam-steering mechanism that adjusts the viewing angle while keeping the horizon stable. This provides 360-degree rotation with a 30-degree field of view allowing the camera horizon and direction of view to operate independently of each other, simulating the experience of navigating the camera during surgery. A survey tool was developed to assess the fidelity of the trainer in these aspects.
RESULTS: A prototype is currently under evaluation, and a feedback survey is underway to evaluate key metrics such as motion, field and direction of view, and horizon stability. Board-certified surgeons will evaluate the model and assess its fidelity as a training device by responding to the survey. Survey data will be used to refine the model and improve its utility and effectiveness as a training tool.
CONCLUSION: The laparoscopic camera navigator trainer offers a practical, cost-effective solution for improving camera navigation skills in surgical trainees. Medical students and interns are often expected to operate a laparoscopic camera during procedures, despite having little to no prior experience with this critical task. This trainer provides a simulated platform for developing the necessary skills to manage camera control and maintain proper orientation during surgery. Ongoing feedback from board-certified surgeons will help refine the model and improve its utility and effectiveness as a valuable tool in surgical education.
