The ability of current surgical luminaires to adapt the light field to different wound shapes is very limited. A system that is able to modify the shape of the light field to the actual wound shape should be able to improve the visual performance of the surgeon during a surgical procedure. A luminaire system has been designed that receives an...

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...

Background – With the growing costs in healthcare and the growing need for care, prediction models offer great opportunities for improving efficiency and patient outcome. With these models, one can manage the different outcomes as efficient as possible and next to that, understand which variables influence the patient’s pathway. The Erasmus...

Windsurfers currently do not wear neoprene gloves when sailing in cold temperatures, as discomfort rapidly develops in the forearms when doing so. Lack of good protection against low temperatures means the hands get painfully cold and numb, limiting sailing time and pleasure. ElectroMyoGraphy (EMG) measurements were done on four forearm muscles...

Sit-snowboards allow a person with the inability to actively use his/her legs to snowboard while sitting. However, existing prototypes do not allow using a chairlift. The goal of this study was to modify a prototype sit-snowboard, MINI, to add chairlift accessibility. MINI has a seat construction and two handlebars which allow the user to steer...

Diffuse reflectance spectroscopy (DRS) allows spectral tissue sensing through optical fibers at the tip of a needle, endoscope, or other medical device. A so-called photonic tool could be applicable in a variety of application areas to aid in diagnostic decisions or to support image-guided procedures. The use of light in combination with medical...

Background: An ablation catheter with integrated high-frequency single element ultrasound transducers has been developed by Philips Research, which makes it possible to assess tissue-depth and lesion formation in real-time. The interpretation of the acquired ultrasound M-mode images is difficult due to a combination of cardiac motion and motion...

Aseptic loosening is the major failure mode for hip prostheses. Currently, loosened prostheses are revised during open surgery. Because of a high complication rate, this demanding procedure cannot be performed in patients with a poor general health. We are developing an alternative minimally invasive refixation procedure that leaves the...

Abstract - When surgically drilling blind holes in bone using a Water Jet (WJ), control over the resulting depth is a challenging issue of paramount concern. This thesis was part of a project aimed at replacing the awl and mallet technique used in traditional microfracture procedures with an arthroscopic high-pressure WJ instrument is capable of...

Abstract—Percutaneous needle insertion is a minimally invasive technique, in which intervention effectiveness depends on needle placement accuracy. Targeting specific areas is difficult as needle trajectory is influenced by the highly variable and unpredictable nature of soft tissue. Furthermore the physician receives very limited information,...

Percutaneous procedures are minimally invasive medical procedures that use needles to locally operate on a target in a patient’s body. The precise placement of the needle in the body is a challenging task that can affect the quality and efficiency of these procedures. Needle insertion accuracy may be improved by robot-assisted control of...

To improve arthroscopic skills, orthopaedic residents train on medical simulators and cadaveric training courses. Some medical simulators provide feedback while cadaveric specimen offer the most realistic training environments. Providing objective feedback while training on cadaveric specimen will be an major improvement to the cadaveric...

Vibration in moving mechanisms and manipulators is almost always present due to manufacturing tolerances, assembly errors and non-uniform density of materials. Small errors in parameters such as mass and length may result in a non-balanced mechanism producing shaking forces. Normally a mechanism would be balanced using a trial and error method,...

Very preterm infants need support to survive. This support almost always incorporates respiratory support in the form of pressure and additional oxygen. Since late 2010 multiple resuscitation councils have advised oxygen saturation targets after birth. An observational study was conducted to observe to which extent the European Resuscitation...

Endovascular interventions are a type of minimally invasive surgery used to diagnose and treat vascular conditions. Long, thin and flexible medical devices like catheters are percutaneously inserted into the blood vessels. Time-action analysis has shown that the navigation of the medical devices from the access to the destination site is...

Nowadays, drug eluting stents (DES) are the treatment of choice for de novo atherosclerotic lesions. Novel DES are shifting to polymer-free (PF) drug delivery in order to avoid the problem of late stent thrombosis associated with long term polymer presence in the vessel lumen. The scope of this study was to assess the potential of a microporous...

The current method of minimally invasive harvesting the sural nerve in infants takes too much time. To reduce harvesting time a new Minimally Invasive Nerve Dissector (MIND) was designed. The MIND reduces instrument change by combining the two most used functions of the currently used instruments: firstly, the movement of the graft with the hook...
