Funnel-shaped retrieval device for wrapping large colorectal resection specimens.
Endoscopic submucosal dissection (ESD) has facilitated en bloc resection of large colorectal tumors [1]. The retrieval of a moderately sized specimen after ESD is common with use of a net forceps [2]. It is difficult however to retrieve a large colorectal specimen without any damage because of the typical anatomy of the anal canal with its narrow lumen, which sometimes results in the failure of...
متن کاملnumerical simulation on wind flow over step-shaped cliff topography with rough surface
to enhance the understanding of the impact of obstacle buildings on pollution transportationand dispersion in the atmospheric boundary layer, it is necessary to know the atmospheric flow characteristics over terrains. wind flow characteristics in a boundary layer over a step-shaped cliff topography model with rough and smooth surfaces were studied numerically using computational fluid dynamics ...
متن کاملA New Endoscopic Technique for Examination of Esophageal Stenosis: The Funnel-shaped Transparent Cap Technique
We have devised a funnel-shaped transparent cap for the endoscopic diagnosis and treatment of stenosis in the digestive tract. This funnel-shaped cap is made of highly transparent methacrylic resin. A 73-year-old woman with reflux esophagitis (categorized as grade D by the Los Angeles Classification) visited our hospital with the chief complaint of dysphagia. She was examined using an endoscope...
متن کاملFabrication of the funnel-shaped three-dimensional plasmonic tip arrays by directional photofluidization lithography.
Plasmonics allow localization of an electromagnetic (EM) field into nanoscale "hotspots", a feature that is of technological significance due to potential applications related to spectroscopic sensing and nanofocusing. In relation to this, many researchers have sought to fabricate metallic nanostructures with sharp edges, as they provide much higher EM field enhancement compared with rounded st...
