Hupkens, Lisanne (author)Goal: Nerve injury is a typical complication of a fasciectomy, a surgical treatment for Dupuytren's contracture. This research focuses on the creation of a surgical device to prevent this medical complication.<br/>Design: A mechanical feedforward-based device with a spreading and cutting mechanism was proposed. Stretching the target tissue...master thesis 2023

Aydin, Güven (author)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...master thesis 2023

Ackermans, Bas (author)Pectus Excavatum (PE) is a common deformity of the thoracic wall, characterized by a depression of the sternum. In the current golden standard for surgical correction of PE, the deformity is instantaneously corrected, causing severe and prolonged post-operative pain. The goal of this study is to design and validate a novel implant to slowly...master thesis 2023

Robijns, Daisy (author)Vitrectomy is an often performed procedure during eye surgery and requires a high-precision vitreous cutter. The production of these precise and lightweight vitreous cutters sets high demands on the manufacturing process. Trained technicians must assemble the device step by step and continuously check and validate the manufacturing process....master thesis 2022

Lucas, Valentin (author)Retinal detachment occurs when liquid slips behind the retina and does not allow the latter to lay flat on the posterior region of the eye. It alters the vision of the patient, hence requiring surgery to be corrected. In some cases, retinal detachment can occur after the retina has been treated for other pathologies. <br/>Indeed, more than 20%...master thesis 2022

Schijf, Menno (author)Introduction - Arthritis is a condition causing pain, deformations and loss of motion in human joints. The surgical instruments used to place a specific unconstrained prosthesis that is used to treat an arthritic joint are difficult to use. The objective for this thesis is to improve the current placement procedure by carrying out an analysis on...master thesis 2022

Groen, Gijs-Bart (author)Laparoscopy is a type of minimally invasive surgery in which instruments with long, slender shafts between handle and end effector are inserted through small incisions in the abdominal wall. A laparoscopic aspirator-irrigator (LAI) has a hollow shaft used to evacuate undesirable substances using a vacuum pressure, rinse tissue using a stream of...master thesis 2021

Koot, Berend (author)<b>Background:</b> In vitrectomy, a type of eye surgery, surgery instruments must pass through an incision in the sclera. The architecture of the incision is of great im-portance to the closure of the wound after the procedure and through that the risk for complications like hypotony and endophthalmitis. Current studies suggest that tri-planar...master thesis 2021

Kortman, Vera (author)Gripping slippery, compliant, and irregular tissues during MIS is often challenging using a conventional gripper. A force grip has to compensate for the low friction coefficient between the gripper’s jaws and tissue surface. This study focuses on the development of a suction gripper as an alternative for the well-known tissue gripper. Suction...master thesis 2021

de Kuiper, Mike (author)Background: Colonoscopy is a successful screening method to prevent colorectal cancer (CRC). Biopsies are performed from suspicious tissue spots during the colonoscopic procedure to find cancerous polyps in an early stage of the disease. However, taking multiple biopsies is rather time-consuming and requires many repetitious actions from the...master thesis 2021

Yikilmaz, Semih (author)Developments in minimally invasive surgery such as natural orifice transluminal endoscopic surgery and single port laparoscopic surgery have pushed medical devices to be higher articulated and more dexterous. These surgery methods have proven to greatly decrease bleeding, scar tissue, hospital time, and cost. The procedures involve the...master thesis 2021

Alkemade, Joost (author)Introduction: This research aims to develop a 3D-printed ergonomic handle design for a steerable laparoscopic instrument with minimised part assembly. Steerable laparoscopic instruments are used in minimally invasive surgery (MIS). MIS is a technique where surgeons insert long slender surgical instruments through small incisions of five to ten...master thesis 2021

Verheijen, Daan (author)When inserting a flexible endoscope into a human colon during colonoscopy, limitations in the endoscope design can cause medical implications such as excessive colon stretching and buckling of the endoscope shaft. This thesis proposes a novel propulsion mechanism design for flexible endoscopes which changes the method of insertion as a way to...master thesis 2021

Bloemberg, Jette (author)Standard treatment methods for prostate cancer often result in side-effects because of damage to the surrounding tissue. Magnetic resonance imaging (MRI) guided focal laser ablation to treat prostate cancer reduces the risk of adverse effects by preserving noncancerous tissue. Prostate cancer diagnosis and focal laser ablation treatment both...master thesis 2021

van Zaanen, Pam (author)In the history of medicine and surgery, a slow transition is made from open surgery to minimally invasive surgery. Nowadays, natural orifice transluminal endoscopic surgery (NOTES) is investigated and tested. A NOTES procedure includes flexible instruments, which are inserted through natural orifices such as the mouth, nose, anus or vagina. The...master thesis 2021

Hiemstra, Olivier (author)In recent years, patient specific instrumentation (PSI) has shown to be a promising application of 3D printing in orthopedic surgery. By aiding the surgeon with accurate placement of instruments such as saws or drills, surgeries can be performed faster, and require less surgeon experience. While most of these devices interface directly with the...master thesis 2020

de Kater, Esther (author)Background: During minimally invasive procedures, tissue damage can be limited by using smaller incisions and by using naturally occurring body orifices to reach the intervention site. During these procedures the need can arise to transport tissue. Think of a biopsy or the removal of polyps. This calls for a tool that can transport tissue and is...master thesis 2020
