Problems solved by technology

However, the positioning accuracy of this system is too low and requires complex calculations
Difficult to apply clinically
X-ray, CT and MRT medical imaging technologies can also be used for positioning, but require 3D reconstruction technology, the process is complicated, its accuracy and speed are limited, and there are also problems of radiation damage and unsuitable time-consuming
In summary, there is no relatively simple method to accurately position the capsule endoscope in the body

Embodiment 1

[0030] according to Figures 1 to 2 , the present invention provides a system for finding the position of a capsule endoscope in a non-magnetic cavity with a magnet, which includes a capsule endoscope 10, a magnetic object 20, a data recorder 50, a driving device 40 and an acceleration sensor. The capsule endoscope 10 contains a magnet 11 inside, and the capsule endoscope 10 is located in the non-magnetic cavity 30 . Both the magnetic object 20 and the driving device 40 are located outside the non-magnetic cavity 30 , and the magnetic object 20 moves freely outside the non-magnetic cavity 30 driven by the driving device 40 .

[0031] Considering the influence of the gravity of the capsule endoscope 10 itself, the magnetic object 20 is located above the non-magnetic cavity 30 . The magnet 11 contained inside the capsule endoscope is preferably made into a cylinder or a cuboid, and the magnetization direction is parallel to the symmetrical central axis of the capsule endoscope ...

Embodiment 2

[0038] according to Figure 4 , the present invention provides a system for finding the position of a capsule endoscope in a non-magnetic cavity with a magnet. The three-axis motor 40.1 is divided into three parts and installed on different parts of the frame 60. The human body 30.1 is located under the magnetic object 20 and The shape of the magnetic object is circular, the capsule endoscope 10 is located in the body of the human body 30.1 and contains the magnet 11, the servo 52 is located below the human body 30.1, and the gravity sensor 51.1 is located inside the capsule endoscope 10.

[0039] First, the three-axis motor 40.1 is used to adjust the self-rotation of the magnetic object 20 so that the magnetization direction of the magnetic object 20 is perpendicular to the horizontal plane. The angle between the cut plane and the vertical plane is the magnetic declination. Next, assume that there are two intersecting axes X-axis and Y-axis on the horizontal plane. The prefe...

Abstract

The invention discloses a system and a method for finding the position of a capsule endoscope in a nonmagnetic cavity through a magnet. The system comprises the capsule endoscope, a magnetic object, a data recorder and a driving device. The position of the capsule endoscope in the nonmagnetic cavity can be accurately found by means of mutual relations between the distance and angles of the external magnet object and the capsule endoscope in which the magnet is arranged in cooperation with the data recorder and the driving device without complex computation, radiation or damage, so that the trouble of failure in accurately positioning the conventional capsule endoscope in vivo is eliminated, and a foundation is laid for future high-quality reliable feedback control of the capsule endoscope.

Description

technical field [0001] The invention relates to a digestive tract diagnosis and treatment system, in particular to a system and method for finding the position of a capsule endoscope in a non-magnetic cavity with a magnet. Background technique [0002] With the development of large-scale integrated circuit technology, MEMS, wireless communication, and optical technology, capsule endoscopy, as an effective device for diagnosing intestinal diseases, has been widely studied and developed rapidly. The research on the first generation of capsule endoscope at home and abroad has mature products and a solid research foundation. The M2A produced by Israel's Given Imaging Company, the Endo Capsule developed by Japan's Olympus Company, and the domestic capsule endoscope products of Chongqing Jinshan Technology have been put into the market one after another, and they all occupy a large share. However, since the movement of the first-generation capsule in the intestinal tract relies o...
