Latest Patents

One of Atsushi Ohhata's latest patents involves a viscoelastic composition designed to secure the field of view of an endoscope. This invention addresses the challenge of opaque dark-colored liquids obstructing visibility during endoscopic examinations. The viscoelastic composition is formulated to push aside such liquids, thereby improving the clarity of the view. The composition consists of a substance with viscoelastic properties and water, with specific parameters including a hardness of 550 N/m or less, a viscosity of 200 to 2,000 mPa·s at 25°C, and a loss tangent of 0.6 or less. Additionally, it is preferable for the composition to have an electrical conductivity of 250 μS/cm or less. The method for utilizing this composition involves feeding it from the proximal part of the endoscope through a channel to the distal part.
