An esophagus-assisted peristaltic device

Abstract

The present invention provides an esophageal assisted peristaltic device, which includes a main rod body used to extend into the esophagus, and the lower end of the main rod body is provided with a ring or a ring for sliding contact with the inner wall of the esophagus when the main rod body moves downward relative to the esophagus. The esophageal auxiliary peristalsis device further includes a driving mechanism for driving the pushing body to expand radially to expand the inner wall of the esophagus, and driving the pushing body to retract radially to separate from the inner wall of the esophagus. The driving body can be radially stretched by the driving mechanism to expand the inner wall of the esophagus to form a convex ring on the wall of the esophagus. When the main rod moves downward relative to the esophagus, the pushing body slides into contact with the inner wall of the esophagus and makes the esophagus formed by the support of the pushing body. The convex ring moves from top to bottom, simulating the physiological peristaltic wave of the esophagus, stimulating the autonomic nerve and vagus nerve to form a conditioned reflex, and helping the recovery of esophageal dysfunction.

Description

technical field [0001] The invention relates to a medical device, in particular to an esophageal auxiliary peristaltic device. Background technique [0002] After food enters the esophagus during swallowing, the esophageal muscles contract sequentially under the innervation of the autonomic nerve and the vagus nerve, forming a top-down physiological peristaltic wave to transport food from top to bottom in the esophagus to the stomach. In some patients, such as stroke, craniocerebral injury, and Alzheimer's disease, the central nervous system is damaged, which can lead to gastroesophageal reflux, diffuse esophageal spasm and other symptoms, and these diseases will destroy the physiological peristaltic waves of the esophagus , Disrupt the normal peristalsis of the esophagus, causing the food in the esophagus to fail to enter the stomach. [0003] In response to this symptom, the current clinical treatment mainly uses gastrointestinal motility drugs to promote the release of c...

Problems solved by technology

In some patients, such as stroke, craniocerebral injury and Alzheimer's disease, the central nervous system is damaged, which can lead to gastroesophageal reflux, diffuse esophageal spasm and other symptoms, and these diseases will destroy the physiological peristaltic waves of the esophagus , disturb the normal peristalsis of the esophagus, causing the food in the esophagus to not enter the stomach

[0003] In response to this symptom, the current clinical treatment mainly uses gastrointestinal motility drugs to promote the release of cholinergic receptors to stimulate the gastrointestinal tract and promote the production of gastrointestinal motility, but this treatment has not improved the neurological symptoms of esophageal disorders. Due to the nature of impaired muscle function, the treatment effect is far from satisfactory, and the recovery effect on esophageal peristalsis is very limited
