Culmone, C. (author), Jager, D.J. (author), Breedveld, P. (author)With the increase in Natural Orifice Transluminal Endoscopic Surgery procedures, there is an increasing demand for surgical instruments with additional degrees of freedom, able to travel along tortuous pathways and guarantee dexterity and high accuracy without compromising the surrounding environment. The implementation of follow-the-leader...journal article 2022

de Kater, E.P. (author), Sakes, A. (author), Bloemberg, J. (author), Jager, D.J. (author), Breedveld, P. (author)Tissue transport is a challenge during Minimally Invasive Surgery (MIS) with the current suction-based instruments as the increasing length and miniaturisation of the outer diameter requires a higher pressure. Inspired by the wasp ovipositor, a slender and bendable organ through which eggs can be transported, a flexible transport mechanism for...journal article 2021

Tummers, Fokkedien H.M.P. (author), Hoebink, Jasmin (author), Driessen, Sara R.C. (author), Jansen, F.W. (author), Twijnstra, A.R.H. (author)Introduction: The implementation of advanced minimally invasive surgical (MIS) techniques has broadened. An extensive body of literature shows that high hospital and surgeon volumes lead to better patient outcomes. However, no information is available regarding volume trends in the post-implementation phase of MIS. This study investigated...journal article 2021

Sakes, A. (author), van de Steeg, Ivo A. (author), de Kater, E.P. (author), Posthoorn, P. (author), Scali, M. (author), Breedveld, P. (author)Currently existing tubular transportation systems for the extraction of large tissue masses during Minimal Invasive Surgery (MIS) are subjected to a large amount of operating limitations. In this study, a novel transportation mechanism (patented) was developed inspired by the egg-laying structure of wasps. The developed mechanism consists of...journal article 2020

Henselmans, P.W.J. (author), Smit, G. (author), Breedveld, P. (author)One of the most prominent drivers in the development of surgical procedures is the will to reduce their invasiveness, attested by minimally invasive surgery being the gold standards in many surgical procedures and natural orifices transluminal endoscopic surgery gaining acceptance. A logical next step in this pursuit is the introduction of...journal article 2019

Horeman, T. (author), Kment, Christoph (author), Kerkhoffs, Gino M.M.J. (author), Tuijthof, G.J.M. (author)The goal of this study was to determine the preferred handle design for two degrees of freedom steerable arthroscopic cutter by performing a two-step development approach. The expected usefulness and usability of control components of three entirely different handles were defined by an on-line survey with 101 students and the actual control...journal article 2017

Henselmans, P.W.J. (author), Gottenbos, Stefan (author), Smit, G. (author), Breedveld, P. (author)Follow-the-leader propagation allows for the insertion of flexible surgical instruments along curved paths, reducing the access required for natural orifice transluminal endoscopic surgery. Currently, the most promising follow-the-leader instruments use the alternating memory method containing two mechanical memory-banks for controlling the...journal article 2017

Jelínek, F. (author)Contemporary medical imaging technologies, such as computed tomography or magnetic resonance imaging, play a pivotal role in medical diagnosis, allowing for a relatively fast and non-invasive examination of the human body. In the field of cancer surgery they allow for preoperative detection of tumorous tissue and aid the surgical planning....doctoral thesis 2015

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), Wever, A.M. (author), Denkelman, J. (author), Jansen, F.W. (author)Background This study aimed to identify the frequency of events in the different patient safety risk domains during minimally invasive surgery (MIS) and conventional surgery (CS). Methods A convenience sample of gynecologic MIS and CS was observed. Events were observed and categorized into one of the predefined patient safety risk domains....journal article 2011

Horeman, T. (author), Rodrigues, S.P. (author), Jansen, F.W. (author), Dankelman, J. (author), Van den Dobbelsteen, J.J. (author)Background - To improve endoscopic surgical skills, an increasing number of surgical residents practice on box or virtual-reality (VR) trainers. Current training is mainly focused on hand–eye coordination. Training methods that focus on applying the right amount of force are not yet available. Methods - The aim of this project is to develop a...journal article 2010

Bowel tissue damage is considered one of the most serious forms of lesion, specifically perforation of the bowel. Methods - An experimental setting was used to manipulate healthy pig bowel tissue via two vacuum instruments. During the experiments, two simple manipulations...journal article 2010

Horeman, T. (author), Jansen, F.W. (author), Dankelman, J. (author)Background - The risk of obtaining a postsurgical infection depends highly on the air quality surrounding the exposed tissue, surgical instruments, and materials. Many isolators for open surgery have been invented to create a contained sterile volume around the exposed tissue. With the use of an isolator, a surgical procedure can be performed...journal article 2010
