Extracorporeal magnetic control type intelligent electrical stimulation capsule system based on video image navigation

Abstract

The invention belongs to the field of endoscopes and discloses an extracorporeal magnetic control type intelligent electrical stimulation capsule system based on video image navigation. According to the system, multiple stimulating electrodes are arranged on the outer surface of a shell and connected with an electrical stimulation generator, a main control system is connected with an image sensor, a pressure sensor and the electrical stimulation generator, an intracorporal wireless communication module is connected with the main control system and an extracorporeal electrical stimulation control device, receives electrical stimulation signals of the extracorporeal electrical stimulation control device and transmits the signals to the main control system, the main control system sends an electrical stimulation control command to the electrical stimulation generator according to the electrical stimulation signals, the electrical stimulation generator generates stimulation currents and transmits the stimulation currents to each stimulating electrode, and each stimulating electrode releases the stimulation currents to achieve electric stimulation of alimentary canal wall muscles.

Description

technical field [0001] The invention relates to a system in the technical field of medical devices, in particular to an intelligent electrical stimulation capsule system based on video image navigation and external magnetic control. Background technique [0002] Digestive tract diseases are a large class of diseases that plague modern humans. According to statistics, nearly 20% of people in the United States suffer from various degrees of digestive tract diseases, and the total incidence of digestive tract diseases in China is as high as 30%. The human digestive tract runs from the mouth to the anus. The main organs of the digestive tract, the small intestine and the large intestine, are slender pipes distributed between the trunk organs of the human body. Medical devices with parameter information (including images and other information) in the digestive tract and medical devices that change the movement of the digestive tract are medical devices with clinical application v...

Problems solved by technology

[0003] After searching the prior art, the following relevant technical documents were found: Chinese Patent Document No. CN1061564 Publication (Announcement) Day 2001.02.07 discloses an electronic pill, which consists of an insulating isolation ring and left and right stainless steel electrode shells to form a shell with a built-in battery And the pulse signal generator, the sending period is 3-4 seconds, the envelope duty ratio of the pulse width part is 1:2.5-3.5, the period is 20-28 milliseconds, the amplitude is 1.5-4.5 volts modulation pulse signal, the shape is capsule medicine, Taking or inserting into the human body (anus, vagina), electrical pulses stimulate the stomach, intestines, pancreas, prostate and lymphatic system, but the defects and shortcomings of this technology are: the electronic pill itself cannot be adjusted in position, and can only passively follow the stomach The intestinal peristalsis and digestion, the operator cannot control the position of the electronic pill in the digestive tract. At the same time, after the electronic pill performs electrical stimulation, the operator cannot know the effect of the electrical stimulation, and there is a possibility that the intensity of the electrical stimulation is too large or insufficient. Unable to adjust the strength of the electrical stimulation signal in real time
