Abstract

The embodiments of the present application provide a position finding system for a capsule endoscope, which relates to the technical field of medical devices. The system includes: an angle and attitude acquisition module for acquiring the initial angle and attitude of the capsule endoscope; a capsule endoscope relative position determination module for determining the relative positional relationship between the capsule endoscope and the magnetic field generating device according to the initial angle and attitude; the first position The information determination module is used to move the magnetic field generating device according to the relative positional relationship. When the capsule endoscope is in a fixed state, the magnetic induction intensity of the capsule endoscope in the magnetic field is obtained, and the current position information of the capsule endoscope is determined according to the position information of the magnetic field generating device. The second position information determination module is used to monitor the angular posture of the capsule endoscope when the capsule endoscope is in a moving state, and when the angular posture reaches the set threshold, determine the current position of the capsule endoscope according to the position information of the magnetic field generating device information. Fixed the inability to determine the position of a capsule endoscope in a stationary state.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular, to a method and system for finding the position of a capsule endoscope. Background technique [0002] For the capsule endoscope that is out of the control range, the existing method for finding the capsule endoscope is to make the outer magnet move according to a preset path until the capsule endoscope is attracted by the outer magnet to a vertical posture. The limitation of this method is that the capsule endoscope must be in a freely moving part such as the stomach, and if the capsule is in the intestine, esophagus, or stuck in a certain position, it is impossible to determine where to find the capsule endoscope. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a method and system for finding the position of the capsule endoscope, which can determine the position information of the capsule endoscope ...
