Embodiment Construction

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. Hereinafter, for the convenience of description, the position and posture are also referred to as pose for short, and the capsule endoscope is also referred to as capsule endoscope for short. The capsule endoscope has a built-in magnetic dipole, and the magnetic dipole can also be called a small magnet.

[0037] Please refer to figure 1 Schematic diagram of the initial position and posture of the capsule endoscope in the first embodiment of the present invention, figure 2 It is a schematic diagram of the second position and posture of the capsule endoscope accordin...

Abstract

The invention discloses a control method of a capsule endoscope. According to the method, the position and posture of the capsule endoscope are calculated in real time by a magnetic dipole model and aleast square algorithm, the posture of a capsule lens facing the direction of a pylorus is kept through position and posture control of a large magnet, capsule target positions and posture data are input by a magnetic control platform, the posture of the capsule endoscope is further precisely controlled, the large magnet is driven to keep posture of mechanical motion, and the capsule endoscope can rapidly and accurately move nearby the pylorus and enter the pylorus. According to the technical scheme, the capsule endoscope can be controlled quickly to enter the pylorus after the capsule endoscope examination is completed, the clinical application risk is reduced, the subject experience is improved, and the product competitiveness is enhanced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a control method for a capsule endoscope. Background technique [0002] Capsule endoscopes are gradually moving toward the application stage. Common capsule endoscopes contain camera devices, small magnets (permanent magnets), magnetic sensors, processors, and drive devices. In clinical applications, capsule endoscopes are swallowed Enter the stomach cavity of the human body, traverse the stomach cavity of the human body through an external magnetic control system, and capture images and transmit them to external receiving devices, such as computer graphics terminals or graphics workstations. The external magnetic control system mainly includes a host, a motion control system, and a positioning system. The host can display the current position and attitude of the capsule endoscope and the images captured by the capsule endoscope in real time; the motion control system controls ...
