Steerable medical instruments are used to reach difficult locations in the body during minimally invasive surgery (MIS). Researching these instruments helps to further improve their performance and reduce their size making them even less invasive. However, developing new technology can be expensive and often complete custom test rigs are build...

The availability of laparoscopy in low-income settings has been limited based on the requirements that have to be met to perform this type of abdominal surgery. At the same time, these regions and countries could stand to gain the most from it based on quicker recovery times and a lower chance of infections. Attempts have been made to solve this...

Background: Bilateral tubal ligation (BTL) is the most common method of contraception worldwide because it is safe and effective. However, its accessibility remains unequal among women in rural India, in part due to a lack of laparoscopic equipment. Rural hospitals therefore resort to gas insufflation-less laparoscopic surgery (GILLS) because it...

Prostate cancer is the second most frequently diagnosed cancer in men. A minimal invasive treatment for prostate cancer is transperineal laser ablation (TPLA), which involves inserting a needle containing a laser fibre into the prostate to induce local cell death. The ovipositor of the parasitoid wasp offers a solution to challenges in TPLA, as...

Background: Minimally invasive cancellous bone biopsy is a common medical procedure in which a needle is used to extract a piece of cancellous bone for examination. Unfortunately, this procedure is not always successful, as sometimes the biopsy can slip partially or completely, necessitating a new biopsy. The occurrence of these errors is not...

The objective of this thesis project is to develop an economically viable design for a titanium total ossicular replacement prosthesis (TORP) that caters to the needs of low- and middle-income countries (LMICs). The author focused on addressing the problem from the manufacturing aspect and two primary approaches, additive manufacturing (AM or...

Minimally invasive surgery (MIS) has several advantages over conventional surgery, including reduced damage to the body, less pain, lower infection risk, and faster recovery. However, MIS reduces the amount of space in which clinicians can operate within the body. This often forces them to work around delicate anatomical structures. A new type...

In up to 39% of reduced distal radius fractures, re-displacement of the fracture occurs in the cast. In most cases, the cast becomes too loose as soft tissue swelling decreases over time and the cast no longer provides sufficient support to keep the fracture reduced. This issue could be addressed by introducing a smart memory cast, a cast that...

Treatment of prostate cancer can be done by performing brachytherapy, where radioactive seeds are transperineally implanted in the prostate via needles. A known problem during treatments with needles is the risk of targeting errors caused by the deviation of the needle from the planned path in the prostate. One of the main sources of this error...

Distal cement plug removal in total hip arthroplasty revision is a time-consuming and technically challenging procedure. There is a risk of perforating the femur while drilling in the cement plug. This risk increases when the orientation of the prosthesis tip is excentric. The aim of this study was to design a reusable drill guide that...

Background: The lack of access to electric powered wheelchairs for disabled people in low- and middle-income countries, that suit their rural environments, still remains an issue. Current available electric powered wheelchairs that do adapt to these rural environments are expensive and require complex control algorithms.<br/>Objective: The aim...

The surgical procedure of tissue extraction from the human body for precautionary or curative measures is common in many medical fields. Currently, aspiration catheters are the golden standard, enabling removal by means of a suction force. By Sakes et al., an alternative mechanism is proposed, transporting tissue based on friction, inspired by...

The widespread proliferation of cellular lattices in engineering design has entailed a revolution in the design of lightweight and multifunctional structures. Furthermore, the development of auxetic metamaterials has led to applications in fields ranging from biomedical to civil engineering. However, cellular lattices suffer from the development...

Bipolar electrosurgical vessel sealing is commonly used in human and veterinary medicine. This method of vessel sealing is often preferred over traditional suturing or clipping of blood vessels because it comes with the advantages of reducing intraoperative blood loss and operation time. Most bipolar vessel sealers are disposable. The high costs...

Stiffness perception in laparoscopic surgery has an important role in achieving appropriate tissue manipulation. The need for haptic feedback to perceive tissue stiffness and the reduce in haptic feedback when using laparoscopic instruments suggest an inability to sufficiently experience stiffness perception during laparoscopic surgeries. Better...

Minimally invasive robotic surgery adds benefits to the patients, such as reduced blood loss, less scaring and reduced hospital stay. From the literature research preceding this thesis, some of the major obstacles in robotic surgery are the high costs and limited reusability of the instruments. In order to have more affordable robotic surgery,...

Each year, many people die due to non-natural causes of death, such as accidents, suicide, and murder and manslaughter. In these cases it is often necessary to investigate the cause, manner and time of death, which are investigated by forensic pathologists and the Police. To determine the time of death, the post mortem interval (PMI), the time...

Loosening of pedicle screws after spinal fusion surgery can lead to serious complications and may prevent fusion between vertebrae. This problem, which has increased in recent years, is a more frequent problem in patients with osteoporosis. In this study, we explore the possibility to use an expanding in‐pedicle anchor with the goal of...

Technologies for Low- and Middle-Income Countries (LMICs) need to take <br/> into account local cost, usability and maintenance challenges, and ‘modular’ <br/> device designs can be one way of overcoming these challenges. However, <br/> despite research into the design advantages of these devices, the adoption<br/>challenges have not yet been...
