Den Boer, K.T. (author), De Jong, T. (author), Dankelman, J. (author), Gouma, D.J. (author)Introduction: Laparoscopic surgery is particularly known for its complex technique, which calls for operative analysis of laparoscopic instruments. This study investigates the opinion of experts about clinical problems with instruments occurring during laparoscopic surgery. Methods: A questionnaire was used to obtain the opinions of expert...journal article 2001

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

Chmarra, M.K. (author), Dankelman, J. (author), Van den Dobbelsteen, J.J. (author), Jansen, F.W. (author)Background - Not much is known about the exact role offorce feedback in laparoscopy. This study aimed to determine whether force feedback influences movements of instruments during training in laparoscopic tasks and whether force feedback is required for training in basic laparoscopic force application tasks. Methods - A group of 19 gynecologic...journal article 2008

Verdaasdonk, E.G.G. (author), Stassen, L.P.S. (author), Hoffmann, W.F. (author), Van der Elst, M. (author), Dankelman, J. (author)Background A high incidence of problems with the technical equipment is known to occur during routine laparoscopic procedures. Use of a structured checklist of preparatory measures could help to prevent these problems. This study aimed to determine the extent to which a checklist reduced the number of incidents with technical laparoscopic...journal article 2008

(author)Background- Surgeons may cause tissue damage by incorrect laparoscopic pinch force control. Unpredictable tissue and grasper properties may cause slips or ruptures. This study investigated how different forms of haptic feedback influence the surgeon’s ability to generate a safe laparoscopic grasp while pulling tissues of variable stiffness using...journal article 2008
