Due to the ageing population and the availability of treatments, healthcare costs keep rising. Surgery is one of the big cost items in a hospital. Improvement of workflow, planning and process efficiency can aid in lowering the costs. Inefficiencies or the effect of improvements can only be detected through measurements. Therefore data is needed...

Atrial fibrillation (AF) is the most common form of arrythmia. Without treatment, the heart rhythm usually becomes permanently disrupted and can lead to various heart related complications as stroke or heart failure. Cardiac phantoms are needed for the development of electrophysiological instruments and for training and education of...

Technological developments in the medical world introduce a shift in responsibilities of the surgical team members which might result in waste of talent and skills. The latter might result in disengagement and decreased productivity and thus in illness-related absenteeism. The people pillar of sustainability aims to create a healthy workplace...

One of the main elements for creating an optimal operating room schedule is an accurate surgery duration estimation. Currently, this estimation is only done preoperatively. However, multiple factors during the surgery itself could influence the duration, for example bleeding. Literature showed the possibility of intraoperatively estimating a...

Cardiovascular disease is the number one cause of death in the USA and number two in the Netherlands(1, 2). In addition, it is expected that in 2030 40.5% of the population in America will be inflicted with a form of cardiovascular disease(2). The growing volumes and thereby health care costs will put a strain on hospitals and health care...

Driven by rising health care costs due to factors including advancing technology and an aging population, cost-effectiveness has become an increasingly important aspect of care delivery, with the operating room (OR) being a specific area of interest. By means of a surgical process model (SPM), OR systems can gain an understanding of clinical...

Due to the increasing prevalence of obesity and type 2 diabetes, the occurrence of liver disease has also increased. In the last decade, important improvements have been realised in methods to treat liver disease, especially in the field of image-guided minimally invasive procedures. With the rapidly developing field of minimally invasive...

Laparoscopic suturing can be very time consuming and frustrating for inexperienced surgeons. It is one of the hardest actions to perform in a laparoscopic fashion, but it remains the golden standard. There are alternative fixation methods such as automatic needle passers, knot-tying devices, staplers, tackers and adhesives but they all have...

During the training of new doctors in cystoscopy a problem could occur. When the trainee controls the cystoscope, the supervising doctor is focussed on the scope images on a monitor. Because the supervising doctor is not holding the scope, location feedback is absent. This makes it difficult to determine whether the entire inner surface of the...

Young women who suffer from cancer have a high change of becoming infertile as a consequence of the treatment. They would benefit from an effective fertility preservation method that allows natural conception. A new method, called autotransplantation of ovarian tissue, has much potential but improvements can be made. The method entails that...

Physicians use small variations in the needle insertion force to identify tissue properties and detect membrane punctures during needle insertion. Navigation of a needle towards the target tissue, for example to take a biopsy, is often based on detecting these variations in force. Literature shows that presenting physicians force feedback based...

Introduction: One of the factors that contribute to the total needle-targeting error in medical procedures is needle deflection, which can lead to e.g. hemorrhage, prolonged intervention time and decreased treatment efficiency. This deflection can be defined as the deviation of the needle from its suspected straight insertion path. In this study...

Since a few decades, the use of Minimally Invasive Surgical (MIS) instruments has increased very fast. Minimally Invasive Surgery usesmuch smaller incisions compared to the traditional open surgery. The procedure is less invasive than open surgery and there is minimal damage to biological tissues at the point of entrance of the instrument. This...

Easy access to the current status of a surgery in the operating room (OR) can be beneficial to hospitals since it can improve the working efficiency and reduce the operational costs. Using indoor positioning systems (IPS) to obtain the position information of medical staffs in the OR could be an indirect method to enhance the awareness of the...

Epidural anesthesia is a commonly used anesthesia method during surgery or giving birth to a child. During the insertion of the needle in the back of the patient, the anesthetist has to interpret the different forces which requires extensive skills. To obtain these skills the residents train on patients, which is not without risk. Due to a lot...

Thermal spread is the extend of lateral damage resulting from soft tissue dissection by means of an energetic surgical instrument. Both a true definition of this factor, and a consistent means to quantify it, are still lacking. This study attempts to standardize thermal spread by 1) listing the relevant medical, technical, and statistical...

Epidural anaesthesia is a pain relief technique commonly performed on patients in labor. It requires insertion of a needle into patients back into the epidural space of the spine and inject anaesthetic. It is a blind procedure and anaesthesiologists rely only on the forces felt during needle insertion to determine the position of the needle tip....
