Evaluation of Learning Curve and Peripheral Awareness Using a Novel Multiresolution Foveated Laparoscope

摘要

Laparoscopic surgery relies on effective visualization of areas of interest and surrounding tissue. The limited field of view of traditional laparoscopes increases the risk of peripheral tissue injury. To address this limitation, a multiresolution foveated laparoscope (MRFL) was designed to enhance peripheral awareness while maintaining focus on the area of interest. Peripheral awareness and learner effect were evaluated with novices (n=13) and experts (n=8). These subjects completed a modified Fundamentals of Laparoscopy Surgery task using a traditional laparoscope, MRFL with autotracking (AT), and MRFL without autotracking (NoAT). Subjects using the traditional laparoscope performed better than MRFL AT and MRFL NoAT in task completion time and collision number. The learner effect was steeper with use of MRFL. In multiple tested parameters, MRFL NoAT performed as well as the traditional laparoscope while providing the added benefits of enhanced field of view and multiple viewing perspectives. These findings warrant further development of MRFL.
