New Area in Laparoscopic Hernia Repair: Devices for Mesh Introducing, Placing and Deploying
Background: The modern Meshes for intraperitoneal Ventral hernia repair create a barrier for bowel adhesion beside of capability of incorporation into the abdominal wall. Groin meshes become less irritating by reducing mesh weight and having bigger porosity. In spite of meshes progression and guidelines for the recommended surgical techniques the adaptation of Lap Hernias repair… Continue Reading
Verrotouch: Detection of Instrument Vibrations for Haptic Feedback and Skill Assessment in Robotic Surgery
Objective: Surgeons currently rely on visual cues to compensate for the lack of haptic information during robotic minimally invasive surgery (RMIS). We have developed VerroTouch, an RMIS accessory that provides surgeons with realistic audio and haptic feedback of instrument vibrations. This system has been implemented in both a box-trainer and a live porcine model. The… Continue Reading
The Subxiphoid Approach to Thyroidectomy Using the Ddes, a Flexible, Articulating, Single-incision Platform
OBJECTIVEThe cultural desire to avoid cervical incisions has motivated surgeons to develop alternative approaches to thyroid surgery. The most common technique employs an axillary incision and subcutaneous tunneling for resection of the thyroid. This access is more challenging in the obese patient, limiting the patients who are candidates for minimally invasive thyroid surgery. Further, traditional… Continue Reading
Novel Cmos Image Sensor Technology Improves Diagnostic Accuracy and Enables Economic Viability of Disposable Medical Imaging Devices
Objective/Background Image senor technologies such as charge-coupled devices (CCDs) image sensors have played a major role in digital medical imaging during past twenty years. With technological advancements such as backside illumination (BSI), CMOS image sensors began to take off in medical imaging applications. Novel CMOS-based image sensors offer enhanced image quality, low power consumption, improved… Continue Reading
Electrical Stimulation Therapy (est) of the Lower Esophageal Sphincter (LES) – Emerging Treatment for Preventing GERD in Achalasia Patients Treated With Les Mytomy
Objective of the technology or device – EST of LES is an effective treatment for GERD (Am J Gastro 2011; 106: S6). Chronic LES-EST improves LES pressure, reduces esophageal acid exposure and improves symptoms in GERD patients. Our objective was to see if LES-EST can control GERD in a patient treated with Heller myotomy who… Continue Reading
Gastrectomy and Hepatectomy By Multi Piercing Surgery Using 3-mm Diameter Electronic Control Forceps
INTRODUCTION: It is described in medical documents that Needlescopic Surgery by use of 3-mm diameter forceps is a minimally invasive surgery method which does not damage somatic pain nerves on the body surface. However, when we deal with bigger organs to be operated such as in gastrectomy or hepatectomy, we are faced with the problem… Continue Reading
New Quality in Single Port Surgery – An Innovative Surgical Technique With Fully Reusable Instruments
The recent development of minimally invasive surgery is characterized by the search for ways of further reducing access trauma for example through the use of natural orifices (NOTES) or the concentration of several individual accesses on a single incision (Single Port Surgery, SPS). Meanwhile, commercially marketed instruments have proven the technical and clinical feasibility of… Continue Reading
Notes Transanal Endoscopic Rectosigmoid and Left Colon Resection Using an Innovative Sterile Sigmoid Access Platform With Integrated Endoscopic Overtube
Introduction: NOTES transanal endoscopic rectosigmoid resection was previously demonstrated using the TEM platform (Transanal Endoscopic Microsurgery). However, the length of left colonic mobilization has been limited due to difficulties with instrument reach and tissue manipulation using standard TEM and endoscopic instrumentation. Recently, a novel innovative sterile sigmoid access platform (ISSA, Storz, Tuttlingen, Germany) was developed… Continue Reading
Feasibility of Endoscopic Transumbilical Thoracic Surgical Lung Biopsy and Pericardial Window Creation
BACKGROUND To date there are no practical platforms for performing natural orifice transluminal endoscopic surgery (NOTES) in the thoracic cavity. Using the canine model, this study evaluates the feasibility of single incision transumbilical endoscopic surgery for thoracic exploration, lung biopsy, and pericardial window creation.METHODS Eight dogs were used for this study. A homemade metallic tube… Continue Reading
New Technology for Minimally-invasive Treatment of Symptomatic Grade I and II Hemorrhoids: Prospective Pilot Study With 1-year Follow-up.
Objective. To describe initial clinical experience with new minimally-invasive device for the treatment of symptomatic Grade I and II hemorrhoids. Background. The symptomatic Grade I and II hemorrhoids are currently treated using rubber band ligation or other modalities such as infrared coagulation, RF bipolar energy or direct current. While these methods are relatively simple,… Continue Reading
Real-time 2d-3d Image Converting Software With a Monocular Small Camera Toward the Lesser Invasive Laparoscopic Surgery
<Introduction and Objectives> 3D images for laparoscopic surgery had been rapidly accepted as useful tool especially in suturing maneuvering. Since recent trials such as single port surgery or NOTES require smaller devices, thinner camera will be effective to retain space inside the port. To provide depth cue using smaller endoscope, combination of small monocular endoscope… Continue Reading
A New Robotic System for Single-incision Laparoscopic Surgery: Preliminary Experience
Introduction: The concept of single access procedures has gained a greater attention of general surgeons over the last four years. Despite such a wide momentum, these procedures pose several changes for the operating surgeon, such as impaired eye-hand coordination and restricted manipulation. In this context, robotic-assisted surgery represents a growing discipline designed to enhance the… Continue Reading

Fluorescent Augmentation of Bile Ducts\’ Visualization at Laparoscopic Cholecystectomy By Using Fluorescein and Ultraviolet Generating and Conducting Device
Objective and backgroundThe purpose of this new technique is to improve visualization of the extrahepatic bile ducts at laparoscopic cholecystectomy. The idea depends on the fact that intravenously-administered fluorescein is excreted by the liver and its concentration in bile reaches 500 times that of plasma. Ultraviolet A (UVA) excites fluorescein and causes it to emit… Continue Reading
