Description

Esophagus expansion device used after esophageal mucosa operation

Technical Field

The utility model relates to the technical field of medical equipment, especially in the later stage healing of the stripping operation under the esophageal cancer mucosa, prevent the constrictive apparatus of esophagus shrink.

Background

Endoscopic Submucosal Dissection (ESD) is a new treatment means appearing in recent years, is a technology with good clinical application prospect, enables more early digestive tract cancers to be completely resected under an endoscope at one time, and avoids the pain of an open surgery and the resection of organs.

Compared with the endoscope treatment methods such as laparotomy and EMR, the ESD has the following advantages: 1. the wound is small; 2. the patient may receive multiple treatments at multiple sites; 3. allowing the physician to obtain a complete histopathological specimen for analysis; 4. the resection rate of the tumor with large area and irregular shape or combined ulcer and scar is more than 96 percent to reduce the recurrence probability. The technology is mature, and for the large countries with the cancer of the digestive tract, the application and development of the technology have very important effects on the body health of patients, and the technology is widely developed in various hospitals and plays a very important role in the prevention and control of the cancer of the digestive tract.

The ESD technology is to completely cut off the lesion with the infiltration depth not exceeding the submucosa from the part above the inherent muscle layer, after the lesion is cut off, an artificial ulcer can be formed at the operation part, and the ulcer is slowly healed to form a scar; esophageal lesions, gastroesophageal junction and small gastric body curvature lesions can cause different degrees of stenosis of the cavity after excision by the formed artificial ulcer scar, the larger the area is, the more the degree of surrounding the cavity is, the more prominent postoperative stenosis is, especially the change of the peri-annular disease is. Of course, the stenosis can be prevented by spraying or injecting hormone during the operation, but the effect is not good, and the feeding and water feeding of the patient can still be affected, which may cause more serious consequences for the patient with scar, so that the patient needs to perform operations such as incision and metal stent expansion repeatedly, and the patient is distressed.
