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
A Novel Flexible Over-tube for Advanced Endoscopic Intervention Under Stabilized Visualization With Adjustable Tissue Traction
Background: Advanced endoscopic interventions such as endoscopic submucosal dissection (ESD), full thickness resection, and ultimately NOTES, have yet to be clinically disseminated, mainly due to technical challenges in optimizing endoscopic visualization and tissue traction. A simple over-tube, compatible with current flexible GI endoscopes and instruments, has been newly developed to improve visualization and tissue traction.The… Continue Reading
A Novel Procedure for Introducing a Large Gauze Into the Corporeal Cavity With a Slim Trocar (tornado Procedure)
1. Objective of the technology: An intracorporeal gauze is used during laparoscopic procedures for hemostasis, blunt dissection, suction filtering, and organ retraction. The current laparoscopic technique involves an advanced, single-incision surgery or reduced port surgery that can be performed for certain organs. Small trocars are used during such surgeries. In such procedures, the gauze is… Continue Reading
A Virtual Electrosurgery Simulator for Teaching and Training in Safe Usage of Energy
ObjectiveTo develop a virtual Reality (VR) simulator to teach the various mechanisms through which injury can occur when using electrosurgery during minimally invasive surgery. Description and MethodsInadvertent thermal injuries do occasionally occur when using electrosurgical devices. The 3 main mechanisms responsible are insulation failure, direct coupling and capacitive coupling. A force feedback enabled VR simulator… Continue Reading
Accurate High-intensity Focused Ultrasound Ablation in a Porcine Liver Model Through Integration of Real-Time Image Guidance, Robotic Navigation, and Elastographic Monitoring
Objective Active research into accurate, minimally-invasive, image-guided destruction of focal hepatic malignancies will expand the population of treatable patients and potentially extend survival. Our objective is to develop an accurate, real-time monitored minimally-invasive ablation system through the integration of high-intensity focused ultrasound (HIFU) ablation within a flexible needle configuration, robotic steerable active cannula guidance, and… Continue Reading
An Externally-Steerable Magnetic Levitation Surgical Camera for Multiple-Point-of-View Laparoscopy
1. Objective of the technology or deviceThe intended purpose of our device, the Magnetic Internal Mechanism (MIM) camera, is to overcome the ergonomic constraints of laparoscopic surgery and in particular of single port laparoscopy (SPL) by providing a new wired miniature surgical camera with a novel magnetic levitation system. By this innovative approach the number… Continue Reading
Arm Support Device for Surgeons
arm support device for operating surgeons by mohamed youssef Cairo universityMillions of laparoscopic operations are performed yearly .Studies show that 10- 20% of laparoscopic surgeons suffer repetitive strain injury (musculoskeletal trauma effect following laparoscopic surgeries also it stated that resting operating arm during the procedure will increase both comfort and performance The overall objectives are:--… Continue Reading
Augmented Reality Telementoring (ART) Platform: An Intuitive Method for Teaching Laparoscopic Skills
Objective: Mentorship in laparoscopic surgery continues to evolve. Skills training outside of the operating room supplements, but does not supplant, hands-on training. Telementoring technology provides ways of training from a remote location that may augment self-directed learning with guided yet unobtrusive mentorship. Digital annotation with 2-way audio has been described as an effective telementoring method.… Continue Reading
Back to the Future: Open Cholecystectomy ‘hybrid’ Model Developed Through Historical Re-enactment.
Objective: Cholecystectomy is the most frequently performed general surgical procedure. Prior to Mouret (1987), surgical trainees were routinely exposed to the open procedure which was the gold standard treatment of the time. The aims of reducing postoperative morbidity and length of hospital stay have historically driven the change in surgical approach; from open to laparoscopic,… Continue Reading
Clinical Experience With a Hands-free Internal Liver Retractor in Laparoscopic Bariatric Surgery
<Objective>Endolift (Virtual ports, Richmond, VA) is a new liver retracting device. It is characterized by an internal and hands-free retractor, which does not require an additional port and anchoring to any external device that limits the patient’s position and adds clutter to the operating table. It also enables us to get comparable or better exposure… Continue Reading
Concurrent Limited Incision Ileostomy Reversal and Cholecystectomy via Flexible Laparoscopic Platform
Introduction: The trend towards minimally invasive procedures has progressed rapidly over the past several decades. Novel techniques and new technologies are constantly being introduced to perform increasingly complex procedures through very limited incisions. Utilization of an ostomy site for laparoscopic colorectal surgery has been described. We performed a cholecystectomy and ileorectal anastamosis (IRA) through an… Continue Reading
Console Integrated Stereoscopic Osirix 3d Volume Rendered Images for Da Vinci™ Robotic Surgery
Background The increasing distance between the surgeon and the surgical field is a significant problem in laparoscopic surgery. Robotic surgery, while providing clear advantages for the operator, increases this gap by completely removing force feedback. With the introduction of mixed reality in the robotic era, integrating novel visual enhancement tools with the da Vinci™(Intuitive Surgical… Continue Reading
DDES™ Flexible Single Incision Operating Platform Facilitates an Extended Thoracic Lymphadenectomy via a Trans-hiatal Approach.
Objective:Emphasis on extended lymph node dissection during esophagectomy is increasing. Many propose that the best technique to achieve this goal is to approach the mediastinal portion of the operation trans-thoracically. However, this may increase overall surgical morbidity compared to a purely transhiatal technique. Totally laparoscopic transhiatal esophagectomies have been performed but while better than open,… Continue Reading
