Background <br/><br/>The surgical management of Hepato-Pancreato-Biliary (HPB) cancer poses significant challenges, primarily due to the complexity of patients. However, the role of stereopsis (depth perception) in visualizing three-dimensional (3D) anatomical models remains relatively underexplored. Integrating stereoscopic technologies with 3D...

The human eye is a very delicate yet highly intricate organ, and treatments such as cataract surgery call for meticulous precision. Ophthalmologists hone their skills over years of practice, which they initially acquired during their studies in medical schools. Basic skills such as globe fixation and capsulorhexis training have a very steep...

During a brain tumour resection, a neurosurgeon is constantly navigating a delicate balance between resecting as much of the tumour as possible, while avoiding any damage to healthy brain tissue. This challenge is particularly difficult when the tumour is located in a critical functional area, involved in for example language or motor function....

The availability of laparoscopy in low-income settings has been limited based on the requirements that have to be met to perform this type of abdominal surgery. At the same time, these regions and countries could stand to gain the most from it based on quicker recovery times and a lower chance of infections. Attempts have been made to solve this...

Cataract surgeries using phacoemulsification (phaco) are standard practice, accounting for the large majority of all cataract surgeries. Reliance on sterilization processes has significant environmental implications, giving its energy and resource intensive nature. <br/><br/>This thesis introduces a novel hybrid phaco handpiece design,...

Background: Bilateral tubal ligation (BTL) is the most common method of contraception worldwide because it is safe and effective. However, its accessibility remains unequal among women in rural India, in part due to a lack of laparoscopic equipment. Rural hospitals therefore resort to gas insufflation-less laparoscopic surgery (GILLS) because it...

Prostate cancer is the second most frequently diagnosed cancer in men. A minimal invasive treatment for prostate cancer is transperineal laser ablation (TPLA), which involves inserting a needle containing a laser fibre into the prostate to induce local cell death. The ovipositor of the parasitoid wasp offers a solution to challenges in TPLA, as...

Recently, the world population has crossed 8 million people and it is estimated that out of every three persons two cannot afford surgery (Meara et al., 2015a). Surgery is the primary treatment for one-third of the diseases (Quene et al., 2022), but since 6 percent of all procedures are performed in the poorest countries, where more than one...

Liver cancer ranks seventh in global cancer prevalence and stands as the third leading cause of cancer-related deaths. Surgical resection is considered the gold standard for treatment of liver malignancies and has witnessed a shift toward minimally invasive techniques in recent decades. Surgeons rely on laparoscopic observations, preoperative...

Gastroschisis, a congenital abdominal wall defect located to the right of the intact umbilical cord (UC), results in the herniation of fetal abdominal organs into the amniotic cavity without a protective membrane covering these structures. Complex gastroschisis (CG), comprising approximately 10% of cases, is associated with significantly higher...

Limited access to surgical care in low- and middle-income countries has resulted in the loss of approximately 16.9 million lives annually, accounting for 32% of global deaths. This is more than tuberculosis, malaria and HIV combined.<br/><br/>Several factors contribute to this disparity, including the scarcity of surgical equipment. Despite the...

This research addresses the operational challenges faced by the Sophia Children’s Hospital through a comprehensive analysis of its current state, literature review, and mathematical modeling. A model is created that produces a master surgery schedule, allowing for the allocation of patients to specific specialties, operating rooms, and days. Our...

In this paper, we investigate the behaviour of current progress prediction methods on the currently used benchmark datasets. We show that the progress prediction methods can fail to extract useful information from visual data on these datasets. Moreover, when the methods fail to extract visual information, memory-based methods adopt a frame...

Orthopedic surgeries are identified as one of the most noisy surgeries inside the OR (operation room). The highest noise sound level could reach up to around 130 dB, which is harmful to patients’ well-being and are likely to evoke negative feelings during surgery. In the previous study investigating the emotional experience of patients who...

Purpose: Image-guided surgery can decrease perioperative complication incidences. Augmented Reality (AR) with head-mounted displays (HMDs) provides an accessible method of visualizing 3D preoperative models intraoperatively. This could provide the surgeon with an easy to use intraoperative image-guided surgery system. Image-to-patient...

Surgical scheduling is a complex task that requires consideration of various factors, including the probability of overtime. In this study, we address the research problem of surgery scheduling while accounting for the likelihood of exceeding scheduled operating room (OR) time. To tackle this problem, we employ integer linear programming (ILP)...

Laparoscopic surgery uses small incisions and a camera for abdominal or pelvic operations, with benefits such as shorter recovery time and hospital stay. However, reduced surgeon hand-eye coordination and feedback can lead to excessive applied force and potential tissue damage. Haptic and visual feedback systems have been...

Minimally invasive surgery (MIS) has several advantages over conventional surgery, including reduced damage to the body, less pain, lower infection risk, and faster recovery. However, MIS reduces the amount of space in which clinicians can operate within the body. This often forces them to work around delicate anatomical structures. A new type...

Background : Surgeons performing robotic-assisted laparoscopic surgery experience physical stress and overuse of shoulder muscles due to sub-optimal arm support during surgery. Following background literature research on passive<br/>dynamic arm supports, this report presents and evaluates a novel design.<br/>Objective: To present a novel design...
