This invention discloses a woven scaffold for digestive organs adapted to intestinal peristalsis and its weaving method. The scaffold is woven from several main filaments and several auxiliary filaments on a fixture with protruding pins, forming a first end, a second end, and several main body segments between the first and second ends. The main filaments are woven into the end or main body segments to form a columnar scaffold. The auxiliary filaments are wound from top to bottom around the columnar scaffold formed by the main filaments. The total number of main filaments and auxiliary filaments is not greater than the number of protruding pins in the circumferential direction of the fixture. The tail portion of the main filaments is wound parallel to the auxiliary filaments. This invention uses multiple main filaments to form a columnar scaffold, avoiding the problem of easy breakage when weaving with a single main filament. Furthermore, the use of auxiliary filaments wound around the outer circumference of the main filaments improves the radial support force of the scaffold, making it more adaptable to the variability of the intestine and extending its service life.

The present invention provides a digestive organ endoscope system which allows a user to perceive whether or not the tip of an endoscope instrument inserted along a channel approaches the tip of an endoscope channel portion within a certain distance, thereby being capable of quickly inserting the endoscope instrument up to a position close to the tip of the endoscope channel portion, and thus, it is possible to reduce a procedure time and to prevent a digestive organ from being damaged due to instantaneous protrusion of the tip of the endoscope instrument occurring when the endoscope instrument is quickly inserted.

An object of the present invention is to provide a novel agent for treating, preventing or improving an inflammatory disease or an allergic disease. The present invention provides an agent for treating, preventing or improving an allergic disease, or as an agent for treating, preventing or improving an inflammatory disease or an allergic disease, comprising, as an active ingredient, (±) 5,6-dihydroxy-8Z,11Z,14Z,17Z-eicosatetraenoic acid (5,6-DiHETE). The inflammatory disease can be an inflammatory disease due to an increase of calcium concentration in vascular endothelial cells, and the inflammatory disease can be an inflammatory disease developed in a tissue or organ selected from the group consisting of digestive organs, circulatory organs, respiratory organs, urinary organs, genital organs, brain, skin, eyes, and fat.

The application belongs to the technical field of medical devices, and provides an endoscopic foreign body extraction and expansion device. The application comprises a pair of expansion assemblies and a limiting assembly. The expansion assemblies are located on both sides of the clamping surface of a foreign body forceps, and are used to expand the inner wall of a digestive organ along the long axis direction of the foreign body. The limiting assembly is located outside the expansion assemblies, and limits the expansion direction of the expansion assemblies along the short axis direction of the foreign body. The cross section of the limiting assembly is a hollow H-shaped structure, and the H-shaped structure is filled with the expansion assemblies. The ends of the transverse part of the H-shaped structure are provided with sliding members, and the inside of the H-shaped structure is provided with sliding grooves. The sliding members can slide along the extension direction of the transverse part of the H-shaped structure along with the expansion of the expansion assemblies. The vertical part of the H-shaped structure is provided with an expansion through hole, and the expansion through hole is a through hole parallel to the extension direction of the transverse part of the H-shaped structure. The above arrangement realizes directional expansion along the long axis of the foreign body, and reduces the risk of tissue damage in the operation of extracting the impacted foreign body in the digestive tract.
