Magnetic spiral capsule endoscopy, magnetic spiral capsule endoscopy control system and control method thereof

Abstract

The invention provides a magnetic spiral capsule endoscopy, a magnetic spiral capsule endoscopy control system and a control method thereof. The magnetic spiral capsule endoscopy comprises a capsule endoscopy body and a magnetic shell layer arranged on the periphery of the capsule endoscopy body, and magnetisable materials are spirally wound on the surface of the magnetic shell layer. The magnetic spiral capsule endoscopy control system comprises an external permanent magnet, a permanent magnet control mechanism and the magnetic spiral capsule endoscopy, the permanent magnet control mechanism controls the external permanent magnet to turn over, the external permanent magnet and the magnetic spiral capsule endoscopy generate a magnetic effect, and the magnetic spiral capsule endoscopy is controlled and driven to rotate, move and maintain the posture. According to the magnetic spiral capsule endoscopy control system, effective control over movement and posture keeping of the magnetic spiral capsule endoscopy is achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a magnetic spiral capsule endoscope, a magnetic spiral capsule endoscope control system and a control method thereof. Background technique [0002] At present, digestive system diseases are the most common clinical diseases, among which gastrointestinal diseases account for the largest proportion. Traditionally, the upper and lower gastrointestinal tracts are examined by mechanical insertion, which causes discomfort and pain to patients, reduces patient compliance to a certain extent, and sometimes even requires anesthesia. Wireless capsule endoscopy has the advantages of non-invasive, painless, and no cross-infection, and overcomes the shortcomings of traditional endoscopy such as gastroscopy. It has been used as the first-line inspection method for small intestinal diseases in many parts of the world. [0003] Capsule endoscope components usually include the capsule itself, a bu...

Problems solved by technology

The internal drive has the following disadvantages: 1. The drive depends on the motor, which may cause insufficient battery power; 2. The structure of the microcapsule endoscope becomes complicated, making production difficult and high cost; 3. The moving structure may cause damage to the digestive tract ; 4. Capsule endoscope movement cannot be accurately controlled and the speed is not fast

The conventionally available non-contact forces are only gravity (universal gravitation) and electromagnetic force. Gravity is basically uncontrollable, and electromagnetic force has not yet been researched to better control the movement of capsule endoscopes.
