Problems solved by technology
[0004] However, there are a large number of folds in the digestive system of humans or animals, such as intestines and stomachs. These folds may jam the capsule endoscope so that it cannot perform corresponding posture changes, thereby causing misjudgment of position detection, and the capsule When the endoscope moves with the gastrointestinal tract, it greatly interferes with the positioning results, and it is not reliable to judge the position of the capsule endoscope based on the data fed back by the acceleration sensor (attitude sensor)

The invention discloses a capsule endoscope control system which comprises a capsule endoscope internally provided with a triaxial magnetic sensor, a vitro capsule driver and a control unit, wherein the control unit controls movement of the vitro capsule driver according to data of the triaxial magnetic sensor and / or an external input command so as to regulate the posture and / or position of the capsule endoscope. The capsule endoscope control system can ensure that even if the capsule endoscope is blocked by wrinkles in a biological cavity, as long as the vitro capsule driver moves, magnetic intensity numerical value measued by the triaxial magnetic sensor changes, positioning of the capsule endoscope can be performed, and misjudgment on the position of the capsule endoscope is avoided; under a condition that the capsule endoscope creeps along with the biological cavity, interference on a magnetic intensity data monitoring result is relatively low, the interference of creepage or wrinkles of the biological cavity on positioning of the capsule endoscope can be avoided, and the capsule endoscope can be positioned more reliably.
Description
technical field [0001] The invention relates to the technical field of auxiliary diagnosis and treatment equipment for the digestive tract system, in particular to a capsule endoscope control system. Background technique [0002] With the development of medical technology, capsule endoscopy is widely used in disease diagnosis, which improves the reliability of disease diagnosis. [0003] After the capsule endoscope is put into the biological cavity, the capsule endoscope needs to be positioned. In a typical capsule endoscope, an acceleration sensor (attitude sensor) is provided to realize the positioning of the capsule endoscope. A permanent magnet and an acceleration sensor (attitude sensor) are installed inside the capsule endoscope. When the external magnet approaches the capsule endoscope or the attitude of the external magnet changes, the capsule endoscope changes its attitude due to being attracted by the external magnet, thus Determine the position of the capsule end...
