Embodiment Construction

[0042] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. In the various figures, identical elements are indicated with similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale. Also, some well-known parts may not be shown in the drawings.

[0043] In this application, the term "capsule endoscope" refers to an endoscope that can enter the human body without going through a tube, and should not be construed as limiting its shape, size or size. It uses wireless communication with The external device communicates, thus avoiding the traditional endoscope needing to provide a path for light transmission or information transmission via a tube, thereby avoiding causing pain and trauma to the human body.

[0044] The term "horizontal orientation" refers to the direction indicated by the long axis of the capsule when the polarization direction of the external magnet is...

Abstract

The invention discloses a posture positioning method of a capsule endoscope and a capsule endoscope system. The posture positioning method comprises the following steps: providing an external magneticfield outside the capsule endoscope; providing an internal magnetic field inside the capsule endoscope; acquiring magnetic field data according to the external magnetic field and the internal magnetic field; obtaining acceleration data of the capsule endoscope; and when the polarization direction of the external magnetic field is in a horizontal state, obtaining posture information according to the acceleration data, and when the polarization direction of the external magnetic field is in a non-horizontal state, obtaining posture information of the capsule endoscope according to the acceleration data and the magnetic field data. According to the posture positioning method, the posture information of the capsule endoscope can be accurately obtained when the external magnetic field is in any state, the requirement for the external magnetic field is lowered while accurate posture positioning of the capsule endoscope is achieved, and the capsule endoscope is simple in structure and easy to implement.

Description

technical field [0001] The present invention relates to the field of medical technology, and more specifically, to a posture positioning method of a capsule endoscope and a capsule endoscope system. Background technique [0002] Capsule endoscope is a capsule-shaped endoscope, which integrates batteries, camera devices, communication devices, etc., and can be taken orally into the body of the subject to take pictures of tissues and organs in the body and transmit the photos to an external display device. Compared with traditional endoscopes, capsule endoscopes have many advantages such as no pain, trauma and cross-infection to the subjects, no influence on the normal activities of the subjects, and high diagnostic rate. Therefore, capsule endoscopes are widely used in the medical field. Has been widely used. [0003] During the actual use of the capsule endoscope, it is necessary to obtain the position information and posture information of the capsule endoscope, so as to ...
