Abstract—Introduction: Surgical instruments are stored, transported, cleaned, disinfected, and sterilized in instrument sets. These instrument sets have a predetermined fixed size, which means they cannot be stored or transported efficiently when empty or used efficiently for different types of instruments. This report presents the design of an...

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...

INTRODUCTION Surgical counting of instruments forms a crucial part of safety procedures in the operating room (OR). This process has remained primitive without technological support. The manual count process is time-consuming and places heavy cognitive demands on nurses. Current technological approaches fail to detect the exact and detailed...

In this article, a deep learning method for the shape sensing of continuum robots based on multicore fiber bragg grating (FBG) fiber is introduced. The proposed method, based on an artificial neural network (ANN), differs from traditional approaches, where accurate shape reconstruction requires a tedious characterization of many...

Breast cancer is the most prevalent form of cancer among women, leading to 2.3 million new diagnosis and almost 685,000 deaths in 2020. Currently, one of the preferred treatments is breast conserving surgery (BCS), but its success depends on the correct identification of tumor margins during surgery. A promising optical intraoperative margin...

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...

Technologies for Low- and Middle-Income Countries (LMICs) need to take <br/> into account local cost, usability and maintenance challenges, and ‘modular’ <br/> device designs can be one way of overcoming these challenges. However, <br/> despite research into the design advantages of these devices, the adoption<br/>challenges have not yet been...

<b>Problem:</b> One of the biggest challenges in hospitals today is improving efficiency, (patient) safety and quality of care while cutting on costs. A current reoccurring challenge in the operation department is the coordination of the components involved in making a surgery successful. One of those components is the set of surgical...

Minimally invasive surgery has some major benefits over traditional open surgery for the patient, but makes surgery more complex for the surgeon. Articulating instruments can regain some of the manoeuvrability that is lost by using a small incision. However, in endoscopic neurosurgery such articulating devices do currently not exist, due to...

Purpose<br/>As a result of the worldwide aging population, Vertebral Compression Fractures (VCF) are commonly detected in osteoporotic patients; these can originate from traumatic events or occur spontaneously. The existing VCF devices and their corresponding surgical instruments have their limitations in terms of short- and long-term...

In the field of medical instruments, additive manufacturing allows for a drastic reduction in the number of components while improving the functionalities of the final design. In addition, modifications for users’ needs or specific procedures become possible by enabling the production of single customized items. In this work, we present the...

Objective: To develop a steerable neuroendoscopic instrument (SNI) based on user requirements found by several means of user research, and to evaluate this instrument on usability and safety. Only 5% of the potential intraventricular neuroendoscopy (INE) cases are currently treated with endoscopy. For the other 95%, an endoscopic approach is...

Access to safe and affordable surgery is nothing short of a basic human right and people from all walks of life are entitled to it. But, five people from resource-constrained low and middle-income countries are vulnerable and left to fend for themselves when the need for surgery is a life governing event. Inhabitants of these regions are...

Hospitals are facing enormous financial pressure over the last years. To achieve lower costs, hospitals should invest in smart ways of working to make optimal use of the scarce capacities. A solution can be digitising processes in the hospital to prevent it from making more costs. In line with this founding, planning and scheduling of the...

Energy-based surgical instruments are increasingly used in laparoscopic surgical procedures. For example, the ultrasonic scalpel enables tissue coagulation and -cutting by transferring a mechanical vibration to the tissue. Additionally, real-time sensing is implemented to improve the surgical procedures. Intraoperative ultrasonography is one of...

Surgical removal remains the preferred treatment for tumors. In order to ensure complete removal, a margin of surrounding healthy tissue is removed together with it. Research has found a relationship between the width of this resection margin and tumor recurrence; patient outcome is improved with greater margins. In order to ensure that no tumor...
