Toet, Rowan (author)
Cardiothoracic surgery is a common treatment for cardiovascular diseases. Patients are admitted to the ICU after cardiothoracic surgery for continuous monitoring to prevent or treat postoperative complications as much and as soon as possible. One of these complications is the development of circulatory shock. It is likely caused by one or a...

This thesis presents the research to design a successful high-accuracy, sub-millimetric registration method for an autonomous robot equipped to drill bone for cochlear implant (CI) surgery. Its performance, and thus success, is measured in accuracy, workload, usability and trust. While state-of-the-art (STOTA) research lacks the inclusion of...

Conventional medical instruments are not capable of passing through tortuous anatomy as required for natural orifice transluminal endoscopic surgery due to their rigid shaft designs. Nevertheless, developments in minimally invasive surgery are pushing medical devices to become more dexterous. Amongst devices with controllable flexibility, so...

Introduction: Anastomotic leakage after gastrointestinal surgery has a high impact on patient's quality of life and its origin is associated with inadequate perfusion. Imaging photoplethysmography (iPPG) is a noninvasive imaging technique that measures blood-volume changes in the microvascular tissue bed and detects changes in tissue...

<b>Background:</b> Low bone quality associated with osteoporosis is an increasing health issue. The reduction in bone quality increases the risk of bone fractures and implant failure in osteosynthesis. Implant failure can be avoided by adapting the surgical procedure and postoperative care to the bone quality. This requires knowledge of the...

<b>Background</b><br/>Adolescent idiopathic scoliosis (AIS) with a Cobb angle larger than 45° is a spinal deformity that needs surgical treatment to stop progression and reduce pain. Spinal fusion is a surgical procedure where rods are attached to the spine through screws to diminish the Cobb angle.<br/><b>Objective</b><br/>The metal rods are...

Wrong-level spine surgery (WLS) is a medical error with severe consequences for the patient and medical staff. The current golden standard to prevent WLS during spinal surgery is fluoroscopy images acquired by a C-arm. However, this approach uses ionising radiation and interrupts the standard surgical workflow. To overcome these disadvantages,...

Over the past decades Minimally Invasive Surgery (MIS) has become a standard in abdominal surgery. Due to limited dexterity and bad ergonomics the field of MIS is shifting towards Robot-Assisted MIS (RAMIS). Simultaneously, the field is using increasingly small and steerable instruments to reduce invasiveness. Surgeon now work with fragile...

Minimally invasive surgery (MIS) has developed greatly in the world of surgery in recent years. The use of robotic systems in this field has increased in the past decades. In this procedure, the surgeon requires excellent dexterity and precision. On the other hand, the patient requires safety and minimum incisions during the procedure. These...

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...

Throughout history, different intraocular illumination methods for vitreoretinal surgery have been used and the most common limitations to the state-of-the-art intraocular illumination methods are the glare and reflections created by the illumination device and the relatively small illuminated area. A way to tackle these limitations could be by...

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...

Spinal fusion is a surgical treatment involving stiffening parts of the spinal column to eliminate any relative motion and improve spine stability. A critical part of spinal fusion surgery is the placement of pedicle screws because it is highly complex and can damage the vascular structures and nerves near the vertebrae. To prevent complications...

The spine is an intricate and crucial part of the human body. Unfortunately, spinal conditions such as scoliosis and trauma can cause instability and deformity to the spine. Patients can experience discomfort and pain. Spinal fusion surgery is used to repair and correct severe cases. During this procedure the vertebrae are fused to prevent them...

The upcoming Shaft Actuated Tip Articulated Low Resource Settings (SATA-LRS) platform is in need of a novel design of a strong, foldable beak able to close in parallel. Steerable instruments for minimally invasive surgery (MIS) are used more often but still have some limitations. The end-effectors used are v-shaped, causing...

Augmented reality (AR) promises to be a valuable tool for anatomical education since any given anatomical site can be studied dynamically in three dimensions (3D). Yet, it has not been used with case-based learning in medical education despite the latter's demonstrated benefits. <br/>This research, thus, investigates the potential benefit of 3D...

In patients with oral cavity cancer invading the mandible, a segmental bone resection is performed and the original contour of the mandible is reconstructed with a free fibula flap. Virtual surgical planning is performed prior to surgery to determine the locations and orientations of the osteotomy planes on the mandible and fibula. Currently,...
