The objective of this study was to determine variables that can be used to assess the complexity of surgical movement qualitatively and identify a better way to examine consistency of surgical performance using the amount of variability and structure of variability measure in robot-assisted surgery. We found that surgical skill improvement can be assessed through the investigation of the temporal structure of variability. As the LyE reduced after training, the surgical movement patterns became more consistent. In previous studies, the time to task completion and the total traveled distance have been used to describe surgical skills learning. However, they do not describe all aspects of robotic surgical performance. This is because a surgeon is more concerned with safety and accuracy during the actual surgery rather than time or longer trajectories of the surgical tools. A surgeon is expected to be cautious in order to prevent tissue damage or other complications in operating theater (Hernandez et al. 2004; Sarle et al. 2004; Smith et al. 2001). In addition, our previous studies (Narazaki et al. 2006, 2007) have suggested that traditional variables, such as the task completion time, may partially indicate the extent of proficiency of skill acquisition; they may not provide the whole picture as far as the consistency of performance is concerned.

The method can be applied to simple industrial environments where parts are found at random positions and orientations, as long as a visual system is able to detect their shape features. This approach can be utilized in a number of possible application domains. One is the manipulation of hand tools, e.g. for supplying surgical instruments to the surgeon in an operating theater, where position and illumination conditions are highly controlled. Other domain would be the assistance to the handicapped, concerning to handling tasks. In these domains an effort in developing suitable computerhuman interfaces for each use should be done.

Such examples are comparatively rare and the intrinsic needs of the disabled appear to have attracted more ergonomic attention than those of medical and paramedical personnel, e. g., wheelchair users.21,22 A couple of studies of the ergonomics of interactions between the surgeon and the operating theater nurse and of the design and arrangement of the instrument trolley and tables were made, not by an ergonomist, but by a professor of surgery.23,24

An operating room (OR), also known as an operating theatre, is a healthcare facility that enables surgeons to carry out surgical operations. The majority of ORs worldwide employ cleanroom technology to provide a highly controlled and clean environment for both the patients and the hospital's personnel. It is necessary to maintain a contaminant-free environment for the patient during surgical procedures. Recent studies concluded that 98% of surgical site infections (SSI) were due to the settlement of airborne particles on the patients’ wounds (Chauveaux 2015; Talon et al. 2006). A study conducted by Karlatti and Havannavar (2016) found that post-operational SSI rates were increased when the surgery was performed in unclean surroundings. It has been estimated that nearly 3% to 5% of patients who underwent surgery in clean environments developed SSIs (Singh, Singla, and Chaudhary 2014), whereas surgical procedures performed in ultra clean environments were associated with an SSI incidence rate as low as 1% (Olsen et al. 2016).
