Abstract

The embodiments of the invention provide a method and system for finding the position of a capsule endoscope, and relate to the technical field of medical devices. The method includes the steps that an initial angle and attitude of the capsule endoscope are obtained; a relative position relationship between the capsule endoscope and a magnetic field generating device are determined according to the initial angle and attitude; the north and south poles of the magnetic field generating device are controlled to be adjusted to a state perpendicular to the horizontal plane, the magnetic field generating device is moved according to the relative position relationship to obtain the magnetic induction intensity of the capsule endoscope in a magnetic field when the capsule endoscope is in a fixed state, and when the magnetic induction intensity reaches a maximum value, the current position information of the capsule endoscope is determined according to the position information of the magnetic field generating device; when the capsule endoscope is in a moving state, the angle and attitude of the capsule endoscope are monitored, and when the angle and attitude reaches a set threshold value, the current position information of the capsule endoscope is determined according to the position information of the magnetic field generating device; and the problem that the position of the capsule endoscope in the fixed state cannot be determined in an existing method is solved.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular, to a method and system for finding a position of a capsule endoscope. Background technique [0002] For the capsule endoscope out of the control range, the existing method for finding the capsule endoscope is to make the outer magnet move along 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 movable part such as the stomach. If the capsule is in the intestinal tract, esophagus or stuck in a certain position, the position of the capsule endoscope cannot be determined. Contents 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 a capsule endoscope, which determines the position information of the capsule endoscope by moving an external magneti...
