Embodiment Construction

[0042] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are represented by similar reference numerals. For the sake of clarity, the various parts in the drawings are not drawn to scale. In addition, some well-known parts may not be shown in the figure.

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

Abstract

The application discloses a posture positioning method of a capsule endoscope and a capsule endoscope system. The posture positioning method includes: providing an external magnetic field outside the capsule endoscope; providing an internal magnetic field inside the capsule endoscope; obtaining magnetic field data according to the external magnetic field and the internal magnetic field; obtaining acceleration data of the capsule endoscope; When the polarization direction is in the horizontal state, the attitude information is obtained according to the acceleration data; when the polarization direction of the external magnetic field is in the non-horizontal state, the attitude information of the capsule endoscope is obtained according to the acceleration data and the magnetic field data. The attitude positioning method can accurately obtain the attitude information of the capsule endoscope when the external magnetic field is in any state. While realizing the accurate attitude positioning of the capsule endoscope, it reduces the requirements for the external magnetic field and the capsule endoscope The mirror structure is simple 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] A capsule endoscope is a capsule-shaped endoscope that integrates a battery, a camera device, a communication device, etc., which can be taken orally into the body by the subject to take pictures of tissues, organs, etc. in the body and transmit the pictures To an external display device. Compared with traditional endoscopes, capsule endoscopes have many advantages such as no pain, trauma and cross-infection to the examinee, no influence on the normal activities of the examinee, and high diagnosis rate. Therefore, the capsule endoscope is in the medical field. Has been widely used. [0003] In the actual use of the capsule endoscope, it is necessary to obtain the position information and posture information of the capsule endoscope to assist the operator ...
