Description

A kind of esophagus tumor scalpel for gastroenterology

technical field

The invention belongs to the technical field of medical devices, in particular to an esophagus tumor scalpel for gastroenterology.

Background technique

At present, early symptoms of esophageal cancer (tumor): small tumors in the esophagus usually do not cause obvious symptoms; when the disease reaches the advanced stage, the most common symptom is dysphagia, and the patient may feel that the food is blocked when swallowing food. The symptoms disappear after the soup, and such symptoms can recur repeatedly. As the tumor continues to grow, the esophagus becomes more and more narrow, so that it is difficult to even eat liquid food. The same cause of death, esophageal cancer can also cause indigestion, heartburn, vomiting, choking, and needle-like pain behind the breastbone.

For the treatment of esophageal tumors, most of the esophagus is located in the thoracic cavity, especially when there is a tumor in the middle and lower esophagus, traditional surgical resection requires incision of the esophagus, and then sutures layer by layer, which is difficult to remove and difficult to suture, and the effect of tumor resection Well, conservative treatment mostly adopts chemotherapy and other means, but due to its hidden location, it is difficult to observe the treatment effect.
