Clercx Lao, Maria Sofia (author)Healthcare is a major contributor to the negative effects on the environment, leading to adverse effects on the physical and mental health of people globally (IPCC, AR6). The Dutch healthcare sector alone is responsible for 7-8% of the national carbon footprint, 4,2% of total waste and 13% of raw material extraction (Steenmeijer et al. 2022). ...master thesis 2024

Bloem, Meike (author)This project aims to reduce the environmental impact of an endoscopic product, the Polyp trap. The polyp trap is a single use device, that is used during endoscopy to catch removed polyps. Endoscopy is a department that has a relatively high reliance on single-use devices. This is one of the reasons why endoscopy has a high carbon footprint....master thesis 2023

Huang, ZhiLi (author)Kidney stone disease has become the most common disease of the urinary tract. Flexible ureteroscopy (fURS) is one of the methods to perform diagnosis or treatment for the stones inside the kidney. However, because of the complex structure inside the kidney with multiple calyxes and the limitation of the ureteroscope, surgeons find it difficult...master thesis 2022

Geleijnse, Geert (author), Rieger, B. (author)SignificanceFlexible endoscopes are essential for medical internal examinations. Digital endoscopes are connected to a video processor that can apply various operations to enhance the image. One of those operations is edge enhancement, which has a major impact on the perceived image quality by medical professionals. However, the specific...journal article 2022

Kalloe, Avinash (author), Younis, Rami (author)Endoscopy is a medical procedure in which the inside of the body is looked into. Specifically, the gastrointestinal tract is of interest. This part of the body can be looked into with a swallowable wireless endoscopic pill. The pill contains different components such as different kinds of sensors, a microcontroller, a transmitter and the power...bachelor 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

Snaar, K.A. (author)Background: Ductoscopy is a minimally invasive procedure, using a sub millimeter fiber optical camera, to explore the mammary ductal epithelium for Pathological Nipple Discharge (serous fluid discharged from the milk duct) and breast cancer, detecting lesions up to eight years before other modalities. Although ductoscopy can revolutionize breast...master thesis 2017

Starre, S.F.M. (author)Healthcare is becoming more customer driven (CGI, 2014). Patients become more involved with their own health, and become an expert. The needs of these patients are changing regarding doctors and hospitals. Healthcare therefore becomes more person-centered, which asks for a change of hospitals. The patients are picking the hospital of their own...master thesis 2017

Loeve, A.J. (author)In 2015, a multi-resistant Klebsiella pneumonia bacteria (“MR Klebsiella”) was found in two Olympus video duodenoscopes of the type TJF-Q180V in the Utrecht University Medical Center (“UMC Utrecht”) after the culturing of flush samples (sterile physiological saline), which were sent through the suction and biopsy channels. This report describes...report 2017

Kreeft (student), Davey (author), Arkenbout, E.A. (author), Henselmans, P.W.J. (author), Van Furth, Wouter R. (author), Breedveld, P. (author)A clear visualization of the operative field is of critical importance in endoscopic surgery. During surgery the endoscope lens can get fouled by body fluids (eg, blood), ground substance, rinsing fluid, bone dust, or smoke plumes, resulting in visual impairment. As a result, surgeons spend part of the procedure on intermittent cleaning of...review 2017

(author)Background The aim of this study was to examine the influence of training under direct vision prior to training with indirect vision on the learning curve of the laparoscopic suture task. Methods Novices were randomized in two groups. Group 1 performed three suturing tasks in a transparent laparoscopic box trainer under direct vision followed by...journal article 2015

Plat, A. (author)Obstructive sleep apnea (OSA) is a common sleep disorder. Surgery is sometimes recommended, by specialists, for severe OSA. In that case, an endoscopic investigation with the patient under sedation would take place. By automating the detection of upper airway collapsing from the endoscopic video, we hope to assist doctors in their diagnostic of...master thesis 2014

Loeve, A.J. (author)Flexible endoscopes (long, slender, flexible instruments with a camera and light at the distal end, having working channels to introduce flexible instruments) are used for diagnostic and therapeutic interventions inside the human digestive system and inside the abdomen. Though used for their flexibility, the flexibility of these instruments...doctoral thesis 2012

(author)Background - To improve endoscopic surgical skills, an increasing number of surgical residents practice on box or virtual reality (VR) trainers. Current training is focused mainly 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 2011

Loeve, A.J. (author), Van de Ven, O.S. (author), Vogel, J.G. (author), Breedveld, P. (author), Dankelmann, J. (author)In order to fully benefit from the functionalities of flexible endoscopes in surgery a simple shaft-guide that can be used to support the flexible endoscope shaft is required. Such a shaft-guide must be flexible during insertion into the human body and rigidified when properly positioned to support the flexible endoscope shaft. A shaft-guide...journal article 2010
