Okken, L.M. (author), Chmarra, M.K. (author), Hiemstra, E. (author), Jansen, F.W. (author), Dankelman, J. (author)Various steerable instruments with flexible distal tip have been developed for laparoscopic surgery. The problem of steering such instruments, however, remains a challenge, because no study investigated which control method is the most suitable. This study was designed to examine whether thumb (joystick) or wrist control method is designated for...journal article 2012

Rodrigues, S.P. (author), Horeman, T. (author), Dankelman, J. (author), Van den Dobbelsteen, J.J. (author), Jansen, F.W. (author)It is generally assumed that safety of tissue manipulations during (laparoscopic) surgery is related to the magnitude of force that is exerted on the tissue. To provide trainees with performance feedback about tissuehandling skills, it is essential to define objective criteria for judging the safety of applied forces. To be of clinical relevance...journal article 2011
