Design of a pressure sensing laparoscopic grasper
With smaller incisions, laparoscopic, or minimally invasive, surgery is considered safer for patients than open surgery. However, the safety of current laparoscopic grasping instruments can still be improved. Current devices provide surgeons with limited tactile feedback, and the current …

Electrosurgical Hyperthermia of Tissue and Laparoscopic Product Realization
… necrosis lesion volume and the development of a laparoscopic device based on these results. A theoretical model was derived which shows that the tissue's electrical conductivity has a greater effect on lesion formation than its thermal conductivity. This was characterized by deriving a …

Development of a force-feedback laparoscopic surgery simulator
… more realistic and complete sensations to a laparoscopic surgery simulator than currently available. A survey of the issues surrounding haptic (touch) displays and training for laparoscopic or "keyhole" procedures was performed. A number of primary and secondary sources including surgeon …

Predicting Weight Loss in Post Surgical Laparoscopic Banding Patients
… predict successful weight loss in post surgical laparoscopic banding patients at 6 and 9 months post surgery. Although the EI is commonly used in bariatric presurgical assessment, few studies have found consistent relationships between presurgical factor scores and subsequent weight loss in this …

Quality of life assessment in patients undergoing laparoscopic cholecystectomy
Philipe Mouret performed the first laparoscopic cholecystectomy in 1987, and since then it has become the ‘gold standard’ treatment for symptomatic gallstones. It had undoubted benefits over the conventional open procedure, such as reduced morbidity and mortality, a shorter hospital stay and …

Surgical Outcomes of Laparoscopic Cholecystectomy for Severe Acute Cholecystitis
… this study was to evaluate surgical outcomes of Laparoscopic cholecystectomy (LC) in patients who were diagnosed with severe acute cholecystitis (SAC) and to clarify useful treatment modalities of SAC. Of 112 patients who presented SAC, we selected 99 paatients and divided them into three groups; …

Flexible support scaffold for organ retraction in laparoscopic surgery
With millions of abdominal surgeries performed annually in the United States alone, abdominal surgery is both a large market and a large medial issue. The entire industry surrounding abdominal surgery has strived to reduce the pain and trauma associated with an operation by reducing the number and …

Operating Room Awareness with the Smart Trocar: Innovative Laparoscopic Surgery
Laparoscopic surgery is a popular alternative to open surgery due to the considerable reduction of recovery time, pain, scaring, and complications. During laparoscopic surgery, operations are performed through small incisions (usually around 1cm) elsewhere in the body. However, limited access to …

Novel Smart Actuation Systems for Single-port Laparoscopic Surgical Instruments
Single-port Laparoscopic surgery (SLS), which utilises one major incision instead of multiple incisions, has gained increasing popularity in the healthcare system in recent years. Compared with the conventional multiport laparoscopic surgery, SLS technique can deliver favourable cosmetic outcomes …

Essential techniques for improving visual realism of laparoscopic surgery simulation.
With the prevalence of laparoscopic surgery, the request for reliable training and assessment is becoming increasingly important. The traditional way of training is both time consuming and cost intensive, and may cause ethical or moral issues. With the development of computer technologies, virtual …

Robotic Cholecystectomy versus Laparoscopic Cholecystectomy: Single institution experience in Korea
… surgical outcomes of robotic and conventional laparoscopic cholecystectomy in inflammatory gallbladder disease patients. Recently, the robotic cholecystectomy has become an attempt at multiple hospitals, but controversy persisted over use of this approach in the treatment of inflammatory …

Pneumatic balloon dilatation versus laparoscopic Heller's myotomy in idiopathic achalasia
Background Both laparoscopic Heller's myotomy (LHM) and pneumatic balloon dilatation (PBD) are widely used in the management of achalasia, but there is still no clarity as to which of these interventions is the best treatment for patients with the condition. Methods Newly diagnosed achalasia …
