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 کاملCollective dynamics of fermion clouds in cigar-shaped traps
The propagation of zero sound in a spin-polarized Fermi gas under harmonic confinement is studied as a function of the mean-field interactions with a second Fermi gas. A local-density treatment is compared with the numerical solution of the Vlasov-Landau equations for the propagation of density distortions in a trapped two-component Fermi gas at temperature T = 0.2TF . The response of the gas t...
متن کاملA Novel Funnel-Shaped Flap for Reconstruction Surgery after Total Laryngopharyngectomy with Total Glossectomy
Reconstruction following total laryngopharyngectomy with total glossectomy (TLPTG) is challenging. To reconstruct this extended range of mucosal defect, it is necessary to overcome the remarkable discrepancy of apertures of oral and esophageal sides. We report a case of reconstruction surgery for total laryngopharyngectomy with total glossectomy with a funnel-shaped rectus abdominis musclocutan...
متن کاملAcoustic metamaterial panel composed of funnel-shaped cell unit having multi-band negative material properties
This paper presents two dimensional sound-proof acoustic metamaterials having tunable multi-band negative effective mass density. The acoustic metamaterial panel was composed of many periodic funnel-shaped cell units into square lattice. Each unit cell operates as multi-band resonators. By tuning unit cell the local reflected acoustic wave was almost out of phase with the incident wave. It lead...
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...
