“…Movement of economy (path length) and completion time are widely used as common metrics for laparoscopic surgery skills evaluation. Additional considerations are peak speed, average speed, and idle time (Riojas et al 2011;Oropesa et al 2014). We select several metrics from those measures and introduce a feature from video games to design the hierarchical fuzzy assessment system for the CAST system.…”

An assessment system is presented to provide objective assessment results for laparoscopic surgery skills training. Six innovative evaluation metrics are introduced in the design of the proposed system. Like a video game, the system suggests achievable goals that are used to define evaluation metrics for a trainee who is performing a particular training task. To implement the proposed system, a design method of the hierarchical fuzzy system is used. The simulation results and the prototype illustrate the feasibility of the proposed evaluation approach.

“…The Computer Assisted Surgical Trainer (CAST) [1,2,4,5,6] is an intelligent surgical training system that benefits from high flexibility, visual guidance and haptic feedback and independence from expert surgeons' active assistance. The prototype for CAST is being developed at the University of Arizona with the primary goal to raise the trainee to a higher level of proficiency in surgical skills in general, and for use by crewmembers and space station personnel both in space and on Moon and Mars in particular.…”

Medical surgeries in the space environment, including long term space travel (e.g., to Mars) and permanent presence on other planetary bodies (e.g., Moon and Mars), are posing an inherent logistical, and in the absence of appropriately trained personnel (i.e., surgeons), even a potentially life-threatening challenge. As a potential mitigation the use of an existing surgical trainer tool that would allow crewmembers to acquire basic surgical skills is proposed, and to train space station personnel both in space and on the Moon and Mars to hone these skills long-term. Furthermore, this tool would potentially allow for tele-conducted surgeries, akin to the da Vinci Surgical System, controlled from Earth but executed onboard, e.g., the International Space Station. On Earth the surgical trainer can be used to train surgeons and flight surgeons. The efficiency of any surgical training system plays a significant role in its reduction of operative risks and stress associated with insufficient experience of the trainee. The primary goal of such systems is to raise the trainee to a higher level of proficiency without putting patients at risk in the operating room. The prototype for the Computer Assisted Surgical Trainer (CAST) being developed at the University of Arizona realizes an optimal motion-planning algorithm. The underlying system consists of mechanical fixtures equipped with encoders and DC motors. This hardware provides a means to accurately track the tip movements of laparoscopic instruments used in minimally invasive surgery. Furthermore it provides haptic and visual feedback to trainees by using a PID controller and augmented reality visualization. Examples of surgical guidance and the improvement of surgeon performance over time using CAST are presented.

“…This allows us and the trainees to review their performance with respect to a set of metrics such as the economy of movement, time, accuracy, direction profile, etc. [6], [21]. This led directly to the second design layer, namely the Comprehension Layer, which provides a suite of metrics and algorithms for objective performance assessment.…”

“…Our design principles and their subsequent implementation address some of the limitations of the existing systems and advance the state of the art in surgical education, assessment, and guidance in laparoscopic surgery [4], [6], [7], [8], [9], [21], [27], [28]. Our overarching vision is to develop a fully integrated training system that will serve as a ,,cognitive amplifier" for a practicing surgeon.…”
