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 […]
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 […]
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 […]
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 […]
Objective:The POEM procedure for achalasia is a complex therapeutic flexible endoscopic technique, requiring extensive practice to learn. Initial experience with the POEM demonstrates that it has the potential to become the therapeutic procedure of choice in the future. However, in order for this to be achieved, the procedure needs to be simple, safe and easily […]
