Ligtelijn, Sharina (author)For healthcare, an industry that is currently responsible for up to 10% of the global carbon footprint, the transition to carbon neutrality and circularity will be an enormous challenge. As 20-30% of the total hospital waste originates from operating rooms, optimising recovery from these waste streams has the potential to make a significant...master thesis 2021

El Hasnaoui, Nabil (author)Cleaning is an important factor in the reprocessing of hollow medical instruments. Inadequate cleaning disturbs the disinfection and sterilization process and increases the risk of cross-contamination. An automated washer-disinfector is often used for cleaning medical instruments, by using fluid flow. fluid flow induces shear stress at the wall...master thesis 2021

Koot, Berend (author)<b>Background:</b> In vitrectomy, a type of eye surgery, surgery instruments must pass through an incision in the sclera. The architecture of the incision is of great im-portance to the closure of the wound after the procedure and through that the risk for complications like hypotony and endophthalmitis. Current studies suggest that tri-planar...master thesis 2021

Boekestijn, Imke (author)Introduction: In daily practice, at interventional radiology (IR), percutaneous needle placement (e.g. biopsy and ablation) is generally performed under real time guidance of morphological imaging (US or CT). However, in some cases obtaining representative specimen can be challenging causing repeated biopsies or shift to open procedures. And so...master thesis 2021

Bakker, Christiaan (author)Vacuum extraction is a form of assisted vaginal birth where a vacuum cup is attached onto the fetal head by means of suction on which traction force is then exerted to facilitate birth. Vacuum extraction is often regarded as a safer option than the cesarean section and forceps delivery, due to decreased risk of maternal en fetal complications....master thesis 2021

Straathof, Robin (author)Brachytherapy (BT) is an essential component in the treatment of cervical cancer as it allows for locally delivering a high dose to the tumour with minimal trauma to surrounding tissues and organs at risk (OARs). However, in advanced cervical cancer patients commercially available BT applicators are particularly ill-adapted and therefore result...master thesis 2021

Perez, Sharline (author)BACKGROUND: Ovarian cancer is the number eight cause of cancer-related mortality in women around the world and has an incidence of more than 295 000 and mortality of almost 158 000. The most important prognostic factor for the survival of advanced-stage ovarian cancer is the complete resection of all microscopic tumour tissue during...master thesis 2021

Scheepens, Karlijn (author)After surgery, 15% of patients experience problems of excessive scarring, causing disfiguring and impaired function. An incision placed in the wrong direction causes unnecessary skin tension on the wound, pulling the wound edges apart. In order to close the wound, increased collagen disposition is needed. Currently, skin tension lines are used...master thesis 2021

Horsman, Chris (author)In the worlds poorest regions there exists an urgent need for surgical care. Open fractures, one of the Bellwether procedures, are treated in only 42% of the health facilities in low- and middle income countries. Worldwide, external fixation is one of the most important treatment methods for open fractures, providing immobilization to the...master thesis 2020

Blankensteijn, Charlotte (author)Microcatheters are used for endovascular diagnosis and treatment purposes. Variations of this minimally invasive instrument, accompanied by guidewires, are manipulated through the vasculature towards the target of the intervention. The human vascular anatomy can however present complex pathways towards a target, for example a distal tumor....master thesis 2020

Rutten, Roosmarijn (author)Currently between 30% till 50%, some even state up to 70%, of medical and laboratory equipment is reported as out of service, due to small or large technical failures or due to missing knowledge of how to use well-functioning equipment in Low-/ Middle- Income Countries (LMIC). This is not due to the complexity of the required repair, but due to,...master thesis 2020

van Drunen, F.H.J. (author)Background Inter- and intra patient morphological differences and absence of visual feedback make the placement of pedicle screws technically very demanding. As the spine is surrounded by neurovascular tissue, complications can have severe consequences, including paralysis. Guidance techniques are often very expensive and can overexpose surgeons...master thesis 2020

Kan, Matthijs (author)Introduction. In spinal surgery, the misplacement of spinal screws is a problem that causes (severe) pain, bleedings or even paralysis [2]. Screw misplacements are common as navigating in the spine is difficult due to the small vertebral dimensions and a lack of anatomical landmarks [3] [4]. In order to improve the navigational support of spine...master thesis 2020
