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...

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...

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...

In laparoscopic surgery, quality of haptic feedback is reduced compared to conventional surgery, leading to unintentional tissue damage during grasping. From the perspective of haptics, poor mechanical design of laparoscopic instrument joints induces friction and a nonlinear actuation-tip force relation. In this study, a novel laparoscopic...

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...

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...

Laparoscopic suturing is one of the most difficult and time-consuming tasks in laparoscopic surgery. The long instrument shafts, two-dimensional view, and limited space for movement make simple actions, such as grasping and manipulating the needle and thread, difficult in the laparoscopic setting. To simplify the suturing process, the Hornet...

Abdominal gas insufflation creates the necessary space for manipulation of the surgical instruments in laparoscopic surgery. However, it is known to disrupt the normal respiratory mechanics. A novel surgical insufflator, capable of performing individualized pressure adjustments, has been recently developed at Erasmus MC - Sophia Children’s...

Laparoscopic or minimally invasive surgery (MIS) has seen a lot of development. For the patient, laparoscopic surgery has many benefits. However, for surgeons this is not the case. For example, laparoscopic grasper design exhibit play and hysteresis during surgical tasks such as grasping and palpating. This impedes haptic feedback, resulting in...

Background: Ever since the introduction of laparoscopic surgery, researchers have been trying to add steerability to instruments to allow the surgeon to operate with better reachability and less tissue interaction force. Traditional solutions to introduce this often use a combination of springs, cables, pulleys, and guiding structures,...

In the Netherlands, approximately 1.750 people are diagnosed with pancreatic cancer each year. Approximately 20% of these new patients are operated with curative intent. This surgical treatment, called pancreaticoduodenectomy leads to a five-year survival rate of 5-10%. Laparoscopic pancreaticoduodenectomy (LPD) is a complex surgical procedure...

Commercially available laparoscopic surgical robots are not currently equipped with force feedback. This may lead to unnecessary tissue damage when gripping tissue in a laparascopic procedure, as shown in a prior literature study. The goal of this MSc thesis project is the implementation of haptic feedback in a prototype of a master-slave...

Laparoscopic surgery is a part of the Minimal Invasive Surgery (MIS) family and is qualified as a rather new surgical technique. According to a report that is written by the Dutch Healthcare Inspection (DHI) there are no universal norms and standards to assess the minimal performance of the OR team, the equipment and the instruments (Report DHI,...

With the introduction of new techniques and technologies, operative skills became a crucial part of surgical competence, deserving more attention. Implementation of validated simulation modalities into the training curriculum is emphasized. It became obvious that operative skills should be brought to an adequate level of proficiency using...
