Capsule endoscope driving device based on three-dimensional orthogonal magnetic field and control method

Abstract

The invention provides a capsule type endoscope intelligent driving device based on three-dimensional orthogonal magnetic field control and a capsule type endoscope intelligent driving control methodachieved through the capsule type endoscope intelligent driving device, and belongs to the technical field of clinical medicine detection. The capsule type endoscope intelligent driving device comprises three groups of electrified coils, an operating table, a current control circuit module, a signal receiving and processing module and an image PC display module, wherein the three groups of electrified coils are connected with the current control circuit, the current control circuit is connected with the operating table and an external civil power supply, and a display receives image information wirelessly transmitted from an in-vivo endoscope capsule as a basis for specific operation of a medical operator. The success rate of digestive tract disease examination is increased, the disease examination time of medical workers is shortened, and the pressure and treatment cost of hospitals and patients are reduced.

Description

technical field [0001] The invention belongs to the technical field of clinical medical detection, and relates to a capsule endoscope driving device and a control method based on a three-dimensional orthogonal magnetic field. Background technique [0002] At present, the incidence of digestive tract diseases in my country exceeds 13%, and the total number of patients exceeds 150 million, and there is an increasing trend year by year. If early detection and diagnosis cannot be effectively carried out, the late incidence of gastrointestinal diseases will increase significantly in the next 5-10 years. Traditional flexible gastroenteroscopy has brought great pain to patients, and some patients gave up the examination because they could not bear it. For patients with severe gastrointestinal diseases, flexible gastroenteroscopy can easily lead to secondary injuries. Compared with conventional gastrointestinal endoscopes, capsule endoscopes expand the inspection area and field of ...

AI Technical Summary

Problems solved by technology

This single driving mode makes it possible that after the patient swallows the capsule endoscope, the camera of the endoscope may not be aimed at the lesion at all (especially in the stomach), resulting in missed detection, resulting in the failure of gastrointestinal disease inspection;

[0005] (2) Causing discomfort to the human body or damage to the digestive tract

Screw drive, earthworm drive, inchworm drive and paddle drive not only have high requirements on the built-in battery, but also cause serious discomfort to patients

Even with the helical driving method with the smallest driving "action", the helical thread may cause inconvenience for patients to swallow and discharge, and may cause damage when the digestive tract peristalsis. precession efficiency;

[0006] (3) The experimental environment is simple and cannot reflect the complex internal environment of the human digestive tract

The human gastrointestinal tract is curved, folded, and mucus and chyme are attached to the surface, which actually makes the simulation experiment much more difficult
