(author), Stevens, Markus J. (author)Background and objectives Learning epidural anesthesia traditionally involves bedside teaching. Visualization aids or a simulator can help in acquiring motor skills, increasing patient safety and steepening the learning curve. We evaluated the face and construct validity of the TU-Delft Epidural Simulator and the effect of needle...journal article 2019

Beekmans, Steven (author), Lembrechts, T. (author), van den Dobbelsteen, J.J. (author), van Gerwen, D.J. (author)A range of complex percutaneous procedures, such as biopsy or regional anesthesia, rely heavily on accurate needle insertion. Small variations in the mechanical properties of the pierced tissue can however cause deviations from the projected needle path and can thus result in inaccurate placement of the needle. Navigation of a rigid needle...journal article 2017

(author)Medical phantoms can be used to study needle-tissue interaction and to train medical residents. The purpose of this research is to study the suitability of polyvinyl alcohol (PVA) as a liver tissue mimicking material in terms of needle-tissue interaction. Insertions into ex-vivo human livers were used for reference. Six PVA samples were...journal article 2017

Vogt, Mark (author), van Gerwen, D.J. (author), Lubbers, Wouter (author), van den Dobbelsteen, J.J. (author), Hagenaars, Martin (author)Background and Objectives Neuraxial blockade using a midline approach can be challenging. Part of this challenge lies in finding the optimal approach of the needle to its target. The present study aimed at finding (1) the optimal point of insertion of the needle between the tips of 2 adjacent spinous processes and (2) the optimal angle...journal article 2017

van de Berg, N.J. (author), de Jong, T.L. (author), van Gerwen, D.J. (author), Dankelman, J. (author), van den Dobbelsteen, J.J. (author)Steering of needles involves the planning and timely modifying of instrument-tissue force interactions to allow for controlled deflections during the insertion in tissue. In this work, the effect of tip shape on these forces was studied using 10 mm diameter needle tips. Six different tips were selected, including beveled and conical versions,...journal article 2017

Van Gerwen, D.J. (author)Medical needles may not be very popular among patients, but they are exceptionally versatile instruments that have found their way into virtually every clinical intervention imaginable. However, despite their versatility, needles can be very difficult to use, and there is much room for improvement. Improvements can be realized by optimization of...doctoral thesis 2013
