Embodiment Construction

[0032] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0033] In the method for controlling the movement of the capsule endoscope, the movement of the capsule endoscope in the target area (such as the stomach) is generally controlled by controlling the magnitude of the interaction force between the external magnet and the internal magnet of the capsule endoscope. The target area is a closed space, such as a bionic stomach, a model stomach, an isolated animal stomach, or a human stomach. This kind of movement is specifically dragging and walking on the surface of the target area. This method usually has a Uncertainty leads to failure of drag walk.

[0034] The specific implementation manners of the present invention will ...

Abstract

A capsule endoscope control method and system are disclosed, the method includes measuring the magnetic field value of the environment where the capsule endoscope is located; obtaining the critical levitation magnetic field value of the capsule endoscope according to the magnetic field value; according to the The critical levitation magnetic field value adjusts the traction force of the capsule endoscope; and controls the horizontal and / or vertical movement of the capsule endoscope, wherein the movement of the first magnet is controlled by moving the second magnet , the capsule endoscope is in a quasi-suspension state when moving horizontally and / or vertically. The capsule endoscope control method and system of the present application reduce the friction between the capsule endoscope and the wall of the target area during the movement process by controlling the capsule endoscope to be in a quasi-suspension state, so that the scanning of the target area is more accurate.

Description

technical field [0001] The invention relates to the technical field of capsule endoscopes, in particular to a control method and system for a capsule endoscope. Background technique [0002] With the development of magnetically controlled capsule endoscopy, the accuracy of magnetically controlled capsule endoscopy in gastric examination has been consistent with that of traditional gastroscopy, and it is a comfortable and safe method of gastric endoscopy. The magnetically controlled capsule endoscope includes a magnet inside, and the movement of the capsule endoscope in the stomach is controlled by the interaction force between the external magnet and the internal magnet. [0003] When using the magnetically controlled capsule endoscope, the method of dragging and walking on the surface of the stomach is generally adopted. Although this method is an intuitive control method, because the friction between the capsule endoscope and the stomach wall is related to the local envir...
