A Modified Buess Rectoscope for TEM
Objective of the technology. TEM (Transanal Endoscopic Microsurgery) is a minimally invasive endoscopic technique, which offers excellent access and visualization of the surgical field, improving the quality of local excision for rectal lesions with full-thickness excision of the rectal wall. We have modified the Buess rectoscope in order to improve the quality and versatility of… Continue Reading
A New Device for the Assessment of Minimally Invasive Surgical Performance – the Validity of Sequitor.
ObjectiveSeveral methods are currently used in the assessment of surgical performance. The majority depends on repeated expert review of an observed procedure. Sequitor allows identification of skilled motor behaviour using quantitative objective measures to provide additional performance characteristics, which may be advantageous during the acquisition of minimally invasive surgical skills. Description and MethodsA customized, novel… 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
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
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
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
Design and Evaluation of Permanent Magnet-based Probe Having Adjustable Magnetic Force for Bowel Retraction in Laparoscopic Surgery
Objective To develop a permanent magnet-based probe with adjustable magnetic field strength for retraction and controlled release of magnetised tissue during laparoscopic surgery. Method Probe development was conducted using a computer-aided design (Solidworks) and a finite element method package (COMSOL Multiphysics) for simulation and optimization. Two designs were exploited: Design 1 changes the… Continue Reading
Developing and Validating an iPad Based Laparoscopic Trainer
Objective of the technology:Access to facilities that allow one to develop their laparoscopic skills is very limited in the hospital environment and courses can be very expensive. We set out to build a cheap yet effective trainer to allow laparoscopic skill acquisition in the home or classroom environment based on using a tablet as a… Continue Reading
Development of an Intracavitary Perfusion Device for Laparoscopic Hepatectomy With Water-filled Endoscopic Surgery (wafles)
Objective of the deviceIn recent years, the number of hospitals that perform laparoscopic-assisted hepatectomy as a less-invasive approach is increasing with development and improvement in medical devices and the advancement of surgical techniques. However, because the liver has a very rich blood supply, it is important to intraoperatively determine the hepatic vascular distribution for safe… Continue Reading
Development of Metallic Reusable Port for Single Port Surgery: Possibility of Enhancement of Operability and Operation Cost Reduction
Single Port Surgery (SPS) has become used worldwide as a minimally invasive surgery method. However, many SPS ports are polymer-made disposable products, which could cause problems such as steep rise of medical cost or increase of management cost of medical waste, leading to environmental problems. We invented a metallic reusable port for SPS. Smooth fixing… Continue Reading
Duodenal Balloon Occlusion System for Hybrid-notes
(Objective of the device) Recently we introduced Hybrid-NOTES procedure for gastric GIST, which was combined procedure with laparoscopic surgery and flexible endoscope by surgeon and endscopists. During this procedure, we apply endoscope by CO2 gas insufflation but we encountered one problem, which is that CO2 gas flew into small intestine. It made worse laparoscopic view… Continue Reading
