Capsule endoscope driving system

Abstract

The invention discloses a capsule endoscope driving system. The capsule endoscope driving system comprises a permanent magnet and a magnetic field generation device, wherein the permanent magnet is fixed in a capsule endoscope; the magnetic field generation device comprises a rotating mechanism, a movement mechanism and three or more than three electromagnets; all the electromagnets are placed onthe same plane; all the electromagnets are distributed at intervals in an annular array by taking a certain point on the plane as a central point; the rotating mechanism is used for driving the electromagnets to rotate around the central point. According to the capsule endoscope driving system, the electromagnets are mounted in the capsule endoscope and a uniform magnetic field with a changeable direction is generated through a magnetic field generation device; when the capsule endoscope is located in a human body, the rotating mechanism is used for driving each electromagnet to rotate simultaneously, and the direction of a uniform magnetic field can be realized, so that a function of freely moving the capsule endoscope in various directions is realized; meanwhile, the movement mechanism is also used for uniformly controlling the position of an acting region of the uniform magnetic field and preventing the capsule endoscope from being released from the constraint of the uniform magnetic field in a movement process of the capsule endoscope.

Description

technical field [0001] The present invention relates to the technical field of capsule endoscope, and more specifically relates to a driving system of capsule endoscope. Background technique [0002] Capsule endoscopy technology has appeared since the end of the last century. After the patient swallows it, it can take images of the digestive tract and complete the observation of the entire digestive tract system through the peristalsis of the gastrointestinal tract, avoiding greater pain to the patient. After more than ten years of development, the technology of capsule endoscopy has matured day by day. However, judging from clinical feedback, there are still many problems to be solved in capsule endoscopy. The first is the positioning problem. Although the capsule endoscope can inspect the entire digestive tract system, it cannot accurately locate the images and videos taken along the way. For fixed-point application of drugs or other treatment measures to the lesion, prec...

Problems solved by technology

The first is the positioning problem. Although the capsule endoscope can inspect the entire digestive tract system, it cannot accurately locate the images and videos taken along the way. For fixed-point application of drugs or other treatment measures to the lesion, precise positioning is necessary; the second is the driving problem. In the prior art, the capsule endoscope is a passive movement method that uses gastrointestinal peristalsis to move. , it is impossible to control its travel, retreat and stay, which may lead to the inability to obtain detailed detection in important areas

[0003] It is of great significance to solve the driving problem of the capsule endoscope. In the prior art, the capsule endoscope passes through the human digestive tract at one time, and no matter whether it is a healthy part or a diseased part, it is treated equally without distinction. This is very important for the built-in energy supply Systematic capsule endoscope is a kind of "waste". If the capsule endoscope can move forward and backward freely in the human body, and accurately stay at the lesion, the diagnostic efficiency of the capsule endoscope will be greatly improved.
