Wentink, M. (author), Fischer, H. (author), Dankelman, J. (author), Stassen, L.P.S. (author), Wieringa, P.A. (author)Purpose: To evaluate the effect of perspective distortion of wide-angle lenses in laparoscopes on hand-eye coordination during endoscopic manipulation. Methods: Sixteen subjects repeatedly performed a standardized positioning task in a pelvi-trainer under two conditions. The subjects had no prior experience with endoscopic manipulation. In one...journal article 2002

Dankelman, J. (author)With the introduction of minimally invasive surgery (MIS), it became necessary to develop training methods to learn skills outside the operating room. Several training simulators have become commercially available, but fundamental research into the requirements for effective and efficient training in MIS is still lacking. Three aspects of...journal article 2007

Chmarra, M.K. (author), Jansen, F.W. (author), Grimbergen, C.A. (author), Dankelman, J. (author)Aims- Minimally invasive surgery (MIS) requires a high degree of eye–hand coordination from the surgeon. To facilitate the learning process, objective assessment systems based on analysis of the instruments’ motion are being developed. To investigate the influence of performance on motion characteristics, we examined goaloriented movements in a...journal article 2007

Verdaasdonk, E.G.G. (author), Dankelman, J. (author), Lange, J.F. (author), Stassen, L.P.S. (author)Background- Laparoscopic suturing is one of the most difficult tasks in endoscopic surgery, requiring extensive training. The aim of this study was to determine the transfer validity of knot-tying training on a virtual-reality (VR) simulator to a realistic laparoscopic environment. Methods- Twenty surgical trainees underwent basic eye–hand...journal article 2007

(author)The subendocardium is most vulnerable to ischemia, which is ameliorated by relaxation during diastole and increased coronary pressure. Recent clinical techniques permit the measuring of subendocardial perfusion and it is therefore important to gain insight into how measurements depend on perfusion conditions of the heart. Using data from...journal article 2008

Verdaasdonk, E.G. (author), Dankelman, J. (author), Lange, J.F. (author), Stassen, L.P.S. (author)Background - It is desirable that surgical trainees are proficient in basic laparoscopic motor skills (eye–hand coordination). The present study evaluated the use of predefined proficiency criteria on a basic virtual reality (VR) simulator in preparation for a laparoscopic course on animal models. Methods - Twenty-eight surgical trainees who...journal article 2008
