van der Wal, Nienke (author)Introduction- The global incidence of thyroid cancer has risen significantly, prompting the development of innovative surgical techniques. Transoral thyroidectomy offers a scarless alternative, with the transoral endoscopic thyroidectomy vestibular approach (TOETVA) showing promising results. However, CO2 insufflation during TOETVA can lead to...master thesis 2024

de Vries, Barbara (author)Reliable assembly methods are needed to translate new endoscopic probes from the research phase to clinical testing. Design variation complicates standardized assembly and leads to a lengthy process creating inaccurate prototypes, preventing repeatable research. This thesis proposes a strategy for selecting the most effective assembly method by...master thesis 2024

(author), Hamprecht, Axel (author), Voss, Andreas (author), Lokate, Mariëtte (author)Contamination of duodenoscopes is a significant concern due to the transmission of multidrug-resistant organisms (MDROs) among patients who undergo endoscopic retrograde cholangiopancreatography (ERCP), resulting in outbreaks worldwide. In July 2020, it was determined that three different patients, all had undergone ERCP with the same...journal article 2024

Tuijp, Jeroen (author)Endoscopic instruments are integral components of minimally invasive procedures, widely used for diagnoses and treatment of diseases. When navigating the endoscope, it should experience a minimum of friction, while an increase in friction is beneficial for performing the medical procedure. Friction can be reduced by squeeze film levitation,...master thesis 2023

(author), Fiorini, Paolo (author), Poorten, Emmanuel Vander (author)Increased demand for less invasive procedures has accelerated the adoption of Intraluminal Procedures (IP) and Endovascular Interventions (EI) performed through body lumens and vessels. As navigation through lumens and vessels is quite complex, interest grows to establish autonomous navigation techniques for IP and EI for reaching the target...journal article 2023

Geleijnse, G. (author), Veder, L. L. (author), Hakkesteegt, M. M. (author), de Gier, H. H.W. (author), Rieger, B. (author), Metselaar, R. M. (author)Objectives: Digital endoscopes are connected to a video processor that applies various operations to process the image. One of those operations is edge enhancement that sharpens the image. The purpose of this study was to (1) quantify the level of edge enhancement, (2) measure the effect on sharpness and image noise, and (3) study the...journal article 2023

Sterke, F. (author), van Weteringen, Willem (author), Ventura, Lorenzo (author), Milesi, Ilaria (author), Wijnen, René M.H. (author), Vlot, J. (author), Dellacà, Raffaele L. (author)Background: Abdominal compliance describes the ease of expansion of the abdominal cavity. Several studies highlighted the importance of monitoring abdominal compliance (C<sub>ab</sub>) during the creation of laparoscopic workspace to individualize the insufflation pressure. The lack of validated clinical monitoring tools for abdominal...journal article 2022

de Kuiper, Mike (author)Background: Colonoscopy is a successful screening method to prevent colorectal cancer (CRC). Biopsies are performed from suspicious tissue spots during the colonoscopic procedure to find cancerous polyps in an early stage of the disease. However, taking multiple biopsies is rather time-consuming and requires many repetitious actions from the...master thesis 2021

Verheijen, Daan (author)When inserting a flexible endoscope into a human colon during colonoscopy, limitations in the endoscope design can cause medical implications such as excessive colon stretching and buckling of the endoscope shaft. This thesis proposes a novel propulsion mechanism design for flexible endoscopes which changes the method of insertion as a way to...master thesis 2021

(author)The fields of Minimally Invasive Surgery (MIS) and Natural Orifices Transluminal Endoscopic Surgery (NOTES) strive to reduce the level of invasiveness by entering the body through smaller incisions and natural orifices. Hyper-redundant snake-like instruments can help in this pursuit of reducing invasiveness. Such instruments can pass along...journal article 2020

(author)perating room planning is a complex task as pre-operative estimations of procedure duration have a limited accuracy. This is due to large variations in the course of procedures. Therefore, information about the progress of procedures is essential to adapt the daily operating room schedule accordingly. This information should ideally be...journal article 2020

van der Plaats, Lisa (author)The quality of rigid endoscopes deteriorates during clinical use due to the sterilization process, mechanical forces and wear and tear during regular use. Regulations and standards on ensuring the quality of these instruments are currently non-existent or contain only qualitative measures, resulting in subjective examinations . Defective rigid...master thesis 2019

Beydilli, Esad (author), Abdellaoui, Zakaria (author)Endoscopic devices are used in the medical world to inspect the gastrointestinal tract. Because there are some complications with wired endoscopy, such as reaching the small intestine, there is a need for new methods to do endoscopy. Therefore an endoscopic pill is invented which can be used to do measurements in the gastrointestinal tract. This...bachelor thesis 2019

Brouwer, I.N. (author)Sealing constructions are frequently used in reusable instruments to prevent the loss of fluids or gasses in a construction by obstructing flow through the glands in the interface of two or more separate parts, and may be applied to seal patients' body fluids. Patient material contains various types of microorganisms, and with the increase of...master thesis 2017

Posthoorn, P. (author)Current endoscopic devices cause great discomfort to the patient because they need to be pushed from outside the patient to manoeuvre through the intestine. Self-propelling endo- scopic concepts have been proposed, but these cause unnecessary trauma to the patient or are unable to travel to the end of the large intestine and back. This study...master thesis 2017
