Problems solved by technology

[0002] After esophageal submucosal dissection, the esophagus is likely to be narrowed due to the continuous inflammatory reaction of the wound surface and the shrinkage and deformation of the wound surface during the scar formation process
[0003] At present, the method to prevent and treat esophageal stricture after esophageal submucosal dissection is to insert an expansion balloon under the endoscope to shape the esophagus, but the expansion balloon can only be used for temporary shaping, and it will also affect the wound site. Administration of inflammatory response affects wound healing

Abstract

The invention discloses an esophageal stent device with medicine carrying and shaping functions, which relates to the technical field of medical instruments and comprises a shaping stent and a medicine bag. The shaping stent is an elastic net-shaped stent, the whole shaping stent is tubular, and the shaping stent can be folded inwards in the radial direction to form a bundle; the medicine bag is an annular soft bag body, the inner annular face of the medicine bag covers the outer circumferential face of the shaping stent, a medicine filling opening used for filling medicine into a bag cavity of the medicine bag is formed in the medicine bag, and a plurality of medicine slow-release micropores used for releasing the medicine in the bag cavity are evenly distributed in the outer annular face of the medicine bag. The device provided by the invention is used for esophageal administration and shaping after esophageal submucosal dissection.

Description

technical field [0001] The invention relates to medical device technology, in particular to a technology of an esophageal stent device with both drug loading and shaping. Background technique [0002] After esophageal submucosal dissection, the esophagus is likely to be narrowed due to the continuous inflammatory reaction of the wound surface and the contraction and deformation of the wound surface during the scar formation process. [0003] At present, the method to prevent and treat esophageal stricture after esophageal submucosal dissection is to insert an expansion balloon under the endoscope to shape the esophagus, but the expansion balloon can only be used for temporary shaping, and it will also affect the wound site. Administration of inflammatory response will affect wound healing. Contents of the invention [0004] Aiming at the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide an esophageal stent ...
