Background: Laparoscopic surgery is increasingly present in our midst. There are some complications related to the use of portal namely bleeding, internal hernia, pain and bruising of the wall. The closing of the gates in our view it is important to minimize complications on bariatric surgery . There are on market tools that greatly facilitates […]
INTRODUCTION Tissue percent oxygenation levels are affected by the amount of compression applied, the purpose of this study was to develop a method to evaluate the change in tissue oxygen saturation level during compression and uncompression. During surgery, tissue is compressed for various reasons, including grasping, manipulation and stapling. Excessive compression may irreparably damage tissue […]
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 […]
(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 […]
Introduction: In proctectomy for rectal cancer, to identify the vascularities of the intestine, structures of inferior mesenteric artery (IMA), left colic artery (LCA) and sigmoid artery (SA), it is important to perform safe and curative operations. However, it is difficult to know laparosocopically, where the point of LCA branching off from IMA is and whether […]
