Li, Z. (author)
Endovascular interventions, as emerging medical therapies, utilize blood vessels as conduits to access anatomically challenging regions deep within the body. Within endovascular interventions, one of the prominent challenges involves maneuvering the instrument tip by coordinating insertion, retraction, and torque actions at the proximal end of...

Cardiovascular disease is currently one of the biggest threats to health. Specific types of cardiovascular disease include, but are not limited to, coronary artery disease, cardiac valve disorders, or peripheral arterial disease. The current gold standard for managing these conditions incorporates the use of catheters and guidewires for...

Brachytherapy (BT) is a safe and effective technique to treat prostate cancer that has not spread outside the prostate gland (localised prostate cancer). Nonetheless, in current clinical practice hazards can arise in positioning the BT needles in the prostate for the purpose of irradiation. Intermediate structures can block access to the...

The vital role of surgery in healthcare requires constant attention for improvement. Surgical process modelling is an innovative and rather recently introduced approach for tackling the issues in complex surgeries. The goal of this thesis is to structure the strategies in surgical process modelling and to seek the applications of surgical...

Hospital waste has a major impact on the environment. The worldwide growth of hospital waste is the result of the growing world population and the increase in use of disposables. A circular healthcare economy may contribute to the reduction of hospital waste. The circular economy is a system in which waste is prevented and where waste is reused....

The intraoperative guidance and placement of spinal screws is a complex procedure. High technical expertise is required fromthe surgeons in order to achieve adequate fixation and ensure patient safety by preventing vascular and neurological injuries. The conventional screw placement techniques face several challenges. Surgeons heavily rely on...

Oosting, R.M. (author)
The need for surgery in low- and middle-income countries (LMICs) is tremendous; more people die from treatable surgical conditions than from tuberculosis, malaria and HIV put together. A crucial barrier to surgical care in LMICs is the limited availability of surgical equipment, which results in delays and cancellations of surgeries on a daily...

de Jong, T.L. (author)
Liver carcinoma is in the top five leading causes of cancer death worldwide. Patients often require radiologic interventions in which needles are inserted, for example when taking biopsies, accessing blood vessels or bile ducts, and ablating tumors. Accurate and precise needle placement in interventional radiology is important, but also...

Malalignment of implant components is a root cause for knee prosthesis failure. Patient Specific Surgical Guides (PSSGs) are used to improve the postoperative position of the implant relative to a preoperative planned position. The PSSGs are tailor made to match the patient’s bony anatomy and align drill holes and saw slots relative to the bone....

Kraaij, G. (author)
In the Netherlands about 36.000 total hip prostheses are implanted every year. Survival of these prostheses at 10 year follow-up is 90% in patients older than 70 years at the index operation. In younger patients these results decrease to about 80–85% at 10 years follow-up. The main cause of failure in total hip replacement is aseptic (mechanical...

In this dissertation, we analyse the safe use of medical technology, considering the training of users, technical demands of used devices and instruments, and the surgical workflow. As each of these elements will vary depending on the experience of the user, the equipment used, and variations in the environment; a unique set of parameters for...

Endovascular interventions include a variety of techniques, chiefly involving guidewires and catheters, that give access to the vascular system through small incisions. It is imperative to reach the place of interest quickly and safely. By considering the fact that the composition of guidewires and catheters differ (e.g., in material, diameter,...

Orthopedic surgery is a surgical discipline that is concerned with the treatment<br/>of the musculoskeletal system. Many orthopedic treatments involve cutting or<br/>drilling in bones by using rigid drills or oscillating saws. Using waterjets instead of<br/>conventional instruments can be beneficial due to the absence of thermal damage<br/>and a...

Arkenbout, E.A. (author)
The field of minimally invasive surgery (MIS) is constantly evolving towards the minimization of surgical trauma. Surgical instrumentation enabling this advancement must aid the surgeon, rather than hamper or burden. Surgeon-Instrument Interaction (SII) is of particular importance. Bad SII-design choices during instrument development can...

The surgical light is an important tool for surgeons to create and maintain good visibility on the surgical task. Chapter 1 gives background to the field of (surgical) lighting and related terminology. Although the surgical light has been developed strongly since its introduction a long time ago, the last decades only minor developments have...

van de Berg, N.J. (author)
Needle interventions play an important role both during the diagnosis and treatment of liver cancer. However, due to intermediate anatomical structures, such as the ribs and lungs, deep seated lesions are not always directly accessible. In addition, instrument-tissue interaction forces may cause needles to deflect during insertion. This leads to...

The Operating Room (OR) is a complex environment, where a large variety of patients and diseases can be treated and many unexpected events occur (such as emergency surgeries and unexpected progress of procedures). In practice, OR assistants support OR processes as well as they can, in order to deliver safe and efficient care. Therefore, they...

Contemporary medical imaging technologies, such as computed tomography or magnetic resonance imaging, play a pivotal role in medical diagnosis, allowing for a relatively fast and non-invasive examination of the human body. In the field of cancer surgery they allow for preoperative detection of tumorous tissue and aid the surgical planning....
