System and method for controlling capsule endoscope motion

Abstract

The invention provides a system for controlling capsule endoscope motion. The system comprises an electromagnet power supply system and an electromagnetic coil. A power supply and a waveform control module are arranged in the electromagnet power supply system, and the electromagnet power supply system is electrically connected with the electromagnetic coil. When a human body swallowing a capsule endoscope with a magnet enters a magnetic field generated by the electrified electromagnetic coil, the waveform control module of the electromagnet power supply system provides current with waveforms changing according to a certain frequency for the electromagnetic coil, strength of the magnetic field alternately changes, and the capsule endoscope with the magnet is attached to the gastrointestinal inner wall under attraction of the magnetic field. The magnetic field with the alternately changing strength leads the capsule endoscope to move transversely and horizontally close to the gastrointestinal wall constantly so as to meticulously shoot all positions of the gastrointestinal wall to obtain clear image data, retention of the capsule endoscope caused by the fact that the capsule endoscope is attached to and embedded into the gastrointestinal concave wall due to too large attraction force is avoided, and accuracy and controllability of image shooting in the stomachs is further improved.

Description

technical field [0001] The invention relates to a capsule endoscope, in particular to a control system and method for controlling the movement state of the capsule endoscope in the stomach and intestines. Background technique [0002] Capsule endoscope is a new scientific and technological product of medical development. It is widely used in the clinical diagnosis of various medical diseases. It adopts painless and non-invasive monitoring and diagnosis. After oral administration, it enters the human stomach or intestinal tract, and passes through its lens components. Close-up photographs of the internal stomach or intestinal wall conditions for clinical diagnosis and relief of patients' clinical pain. [0003] After the capsule endoscope enters the body, it needs to image the stomach of the human body. Because the capsule endoscope is in a free state, floating freely in the body fluid, its position is uncertain, and the images taken are too random. People sometimes It is di...

Problems solved by technology

[0003] After the capsule endoscope enters the body, it needs to image the stomach of the human body. Because the capsule endoscope is in a free state, floating freely in the body fluid, its position is uncertain, and the images taken are too random. People sometimes It is difficult to determine the orientation of the captured image, the overall situation in the stomach, or the orientation of the tumor, because it is difficult to control the movement state and track of the capsule endoscope, and the attraction force of the electromagnet to the capsule endoscope It is inversely proportional to the distance between the two, and it is prone to the phenomenon of being absorbed and embedded in the concave wall of the stomach due to the long-term strong attraction of the electromagnetic field, and the process of image shooting may even cause the retention of the capsule endoscope in the stomach
