Abstract

The invention provides a permanent magnet and induction coil based capsule endoscopy space positioning system. The system comprises a vibration module, an extracorporeal traction permanent magnet, an intracorporeal capsule endoscope, a wireless receiving apparatus and a single-chip microcomputer microprocessor. One end of the vibration module is connected with the extracorporeal traction permanent magnet, and a magnetic path is formed between the extracorporeal traction permanent magnet and the intracorporeal capsule endoscope. The intracorporeal capsule endoscope is in wirelss connection with the wireless receiving apparatus which is connected with the single-chip microcomputer microprocessor. The invention further provides a positioning method of the positioning system. Compared with the prior art, the positioning system and the positioning method have the advantages that occupied capsule space is small, position and posture information of the capsule endoscope can be tracked continuously and obtained in time, great convenience is provided for subsequent operations of detection personnel, the positioning method is simple and easy to implement, and the position system is low in cost and safe and reliable.

Description

technical field [0001] The invention relates to an electronic capsule positioning method and the technical field of medical detection. Specifically, it relates to a capsule endoscope space positioning system and positioning method based on permanent magnets and induction coils. Background technique [0002] Capsule endoscopy was first proposed and successfully developed by Israeli experts. It overcomes the pain caused by traditional rigid endoscopy to patients, and can detect organs such as the small intestine that cannot be detected by traditional detection methods. However, there are still many problems in the clinical application of capsule endoscopes, and the positioning and tracking of capsule endoscopes is the most important problem. [0003] With the development of capsule endoscopy, researches on its positioning methods are emerging in an endless stream. Common positioning methods include: positioning based on radio frequency signals, ultrasonic positioning and mag...
