Method for automatic obstacle-crossing of capsule endoscope in living body and system

Abstract

The invention discloses a method for automatic obstacle-crossing of a capsule endoscope in a living body and a system. The method comprises the following steps: step S1: receiving a sensing signal of the position and posture of the capsule endoscope in the living body detected by a sensor in real time; step S2: in the moving process of the capsule endoscope, according to the sensing signal, judging whether the capsule endoscope is hindered in the moving process, if so, turning to the step S3, otherwise, repeating the step S2; and step S3: controlling an external magnet to be moved to drive the capsule endoscope to execute the obstacle-crossing movement. The sensing signal of the sensor is received to judge whether the movement of the capsule endoscope is hindered, and the movement of the external magnet is controlled to drive the capsule endoscope to execute the obstacle-crossing movement, namely the movement of the capsule endoscope can be automatically judged and the capsule endoscope automatically performs the obstacle-crossing operation after the movement of the capsule endoscope is hindered, the difficulty degree of the artificial operation is reduced, the obstacle-crossing efficiency of the capsule endoscope is higher, and the automatic scanning technology of the capsule endoscope can be realized.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for a capsule endoscope to automatically overcome obstacles in a living body. In addition, the present invention also relates to a system for automatically surmounting obstacles in a living body using the capsule endoscope using the above method. Background technique [0002] In the medical field, the application of capsule endoscopy has improved the accuracy of medical diagnosis. When in use, after the capsule endoscope enters the biological cavity (such as the stomach), the medical staff will manipulate the external magnet to move the capsule endoscope to some specific positions in the biological cavity (such as: gastric fundus, cardia, pylorus, etc.) etc.) to check. During the movement, the capsule is likely to be hindered by the protruding tissue in the cavity and cannot continue to move with the external magnet. At this time, the medical personnel usually need t...
