Apparatus for preventing esophageal lumen stenosis after ESD (endoscopic submucosal dissection)

Abstract

The invention discloses an apparatus for preventing esophageal lumen stenosis after ESD (endoscopic submucosal dissection). The apparatus comprises an air sac and an inflation tube, wherein the air sac is in the shape of a tube in the inflation condition, a magnetic force closure device is arranged at the bottom of the air sac, the inflation tube extends into a lumen of the air sac from the magnetic force closure device, and fixing rings are arranged at outside edges of the top and the bottom of the air sac; the magnetic force closure device comprises two or more sealing slices and an inflation hole, wherein the two or more sealing slices are connected in a magnetic adsorption manner, and the inflation hole is adapted to the inflation tube; and a plurality of exhaust holes are formed in the periphery of an exhaust end of the inflation tube, and are in helical arrangement. The apparatus disclosed by the invention can well support an esophagus, can contribute to autonomous eating and drinking of a patient, and is reliable to fix.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an instrument for preventing esophageal lumen stenosis after ESD. Background technique [0002] Endoscopic submucosal dissection (Endoscopic submucosal dissection, ESD) is currently a mature technique for the endoscopic treatment of early gastrointestinal (esophagus, stomach, colorectal) cancer, and the scar formed by wound healing after ESD for early esophageal cancer It may cause different degrees of stenosis of the esophageal lumen. The area of ​​the wound and the proportion of the wound surrounding the lumen are all influencing factors. Generally speaking, the larger the area, the higher the possibility of stenosis and the degree of stenosis after peripheral lesions. At present, Common measures to prevent stenosis are wound hormone injections and oral steroids for patients with high risk of postoperative stenosis. Severe cases will also undergo repeated endoscopic balloon ...

[0002] Endoscopic submucosal dissection (Endoscopic submucosal dissection, ESD) is currently a mature technique for the endoscopic treatment of early gastrointestinal (esophagus, stomach, colorectal) cancer, and the scar formed by wound healing after ESD for early esophageal cancer It may cause different degrees of stenosis of the esophageal lumen. The area of ​​the wound and the proportion of the wound surrounding the lumen are all influencing factors. Generally speaking, the larger the area, the higher the possibility of stenosis and the degree of stenosis after peripheral lesions. At present, Common measures to prevent stenosis are wound hormone injections and oral steroids for patients with high risk of postoperative stenosis. Severe patients will also undergo repeated surgical treatments such as endoscopic balloon dilation and stent placement, which will increase the pain of the patient
