System of non-invasive in vivo minitype device fixed in esophagus

Abstract

The invention discloses a system of an in vivo micro device for intraesophageal noninvasive fixation, which is characterized by comprising an in vitro magnetic field positioning device and the in vivo micro device, wherein the in vitro magnetic field positioning device comprises a permanent magnet and a positioning carrier of the permanent magnet, and the positioning carrier is used to fix the permanent magnet and carries the permanent magnet to position on a specific part of a human body; the in vivo micro device comprises a shell, a functional module and a permanent magnet; the in vitro magnetic field positioning device generates magnetic force attraction to the permanent magnet embedded in the in vivo micro device through the permanent magnet to complete the positioning of the in vivo micro device; and the shell of the in vivo micro device is of a flat capsule shape and is provided with a relatively level shell attached side face, the shell attached side face is parallel to the embedded permanent magnet, and other parts of the shell adopt a streamline type. In the system, the micro device comprises a sensor or an actuator, and the like to meet the requirements on the monitoring and treatment of intraesophageal physiological parameters, and the like. The system has the advantages of no pain, no wound, simple and convenient operation, good tolerance for a patient, and the like.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical device for diagnosing and treating esophageal diseases, in particular to a system for non-invasively fixing micro-device in the esophagus. Background technique [0002] With the acceleration of people's life rhythm and the continuous change of diet structure, the incidence of digestive tract functional diseases is increasing to the first place, among which common esophageal diseases include reflux esophagitis, esophageal cancer, esophageal stricture, esophageal varicose veins , indigestion, functional dysphagia, etc., have brought pain to people physically and mentally. In the process of medical diagnosis and treatment, continuous monitoring or treatment of specific three-dimensional space in the esophagus is often required, such as: identification of reflux esophagitis, whether there is acid reflux or alkali reflux, and the degree of reflux; for esophagus For diseases, continuous e...

Problems solved by technology

In the process of swallowing saliva or food, the esophagus moves in a migratory wave-like motion in which the smooth muscle layer contracts sequentially, and the peristaltic wave produces a certain contraction force. Therefore, to fix a micro-device in the esophagus, it must be able to overcome its own gravity and the force generated by swallowing. thrust, and considering the need for long-term operation, the technology should preferably be painless, non-invasive, and not affect daily life, which is difficult to achieve with existing technologies
