Meaningful assessment method for laparoscopic suturing training in augmented reality

Botden, S.M.B.I. (author), De Hingh, I.H.J.T. (author), Jakimowicz, J.J. (author)

To be an effective training tool, a laparoscopic simulator has to provide metrics that are meaningful and informative to the trainee. Time, path length and smoothness are often used parameters, but are not very informative on the quality of the performance. This study aims to validate a newly developed assessment method for laparoscopic suturing...

Do absorption and realistic distraction influence performance of component task surgical procedure?

Pluyter, J.R. (author), Buzink, S.N. (author), Rutkowski, A.F. (author), Jakimowicz, J.J. (author)

Background. Surgeons perform complex tasks while exposed to multiple distracting sources that may increase stress in the operating room (e.g., music, conversation, and unadapted use of sophisticated technologies). This study aimed to examine whether such realistic social and technological distracting conditions may influence surgical performance...

Visuo-spatial ability in colonoscopy simulator training

Luursema, J.M. (author), Buzink, S.N. (author), Verwey, W.B. (author), Jakimowicz, J.J. (author)

Visuo-spatial ability is associated with a quality of performance in a variety of surgical and medical skills. However, visuo-spatial ability is typically assessed using Visualization tests only, which led to an incomplete understanding of the involvement of visuo-spatial ability in these skills. To remedy this situation, the current study...
