Problems solved by technology

In some patients, the lesion mucosa involved the lumen for a week. When the lesion mucosa was completely stripped, a huge circular wound would be formed in the original lesion area. Since the lesion mucosa was completely stripped and resected, the wound area could only heal through scars after forming ulcers. During the healing process, the scar shrinks from the edges on both sides of the lumen to the center of the ulcer, resulting in narrowing of the lumen in the center of the ulcer, making it difficult or even impossible for patients to eat after surgery

Abstract

The invention relates to an esophagus supporting device which comprises a supporting bag and an air injecting tube. The supporting bag is hollow, and a channel penetrating through the head end and the tail end of the supporting bag is formed. The front end of the air injecting tube is communicated with the supporting bag. The supporting bag is integrally in a cylindrical shape, and a plurality of pits are formed in the surface of the supporting bag. The pits in the surface of the supporting bag can protrude after being inflated, negative pressure is formed between the pits and the esophagus wall, the pits are attached to the esophagus wall as suckers, attaching is firmer, the deviation of the supporting bag in the treating process is avoided, the treating effect is enhanced, and stricture of the esophagus of a patient can be effectively prevented; furthermore, a supporting bar used in cooperation with the supporting bag can be drawn away from the esophagus after the supporting bag is delivered to the right position, the foreign body sensation of the esophagus of the patient is reduced, the comfort level of the patient is increased, and operation is convenient.

Description

technical field [0001] The present invention relates to a medical tool, in particular to an esophagus support device. Background technique [0002] Endoscopic submucosal dissection is an important technique to remove early esophageal cancer. The knife gradually separates the submucosa, so that the diseased mucosa on the surface of the esophagus is completely peeled off from the muscular layer. In some of the patients, the lesion mucosa involved the lumen for a week. When the lesion mucosa is completely peeled off, a huge annular wound will be formed in the original lesion area. During the healing process, the scar shrinks from both sides of the lumen to the center of the ulcer, resulting in the narrowing of the lumen in the central part of the ulcer, making it difficult for patients to eat after surgery, or even unable to eat. SUMMARY OF THE INVENTION [0003] The invention aims to provide an esophagus support device, which can prevent the esophagus stenosis of the patie...
