Problems solved by technology

Among them, the magnetically controlled capsule endoscope can help realize the precise positioning of the capsule mirror in the body, but it cannot solve the problem of slow forward speed and low shooting efficiency of the capsule mirror due to the two-way movement caused by intestinal peristaltic waves.

Embodiment Construction

[0021] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0022] like figure 1 , figure 2 and image 3 As shown, a capsule endoscope magnetic and wheat awn bionic dual driving device includes a capsule mirror body 2, and a magnetic carrier ring 3 is fixed outside the capsule mirror body 2 along its side, and the carrier ring 3 can be made of soft magnetic materials. As a result, the capsule lens body 2 is driven to move together by the traction of the magnetic block outside the body. The carrier ring 3 is a cylindrical structure with front and rear openings to ensure that the shooting end of the capsule mirror body 2 is exposed and does not affect its shooting images.

[0023] The carrier ring 3 is provided with a number of tail whiskers 1. The tail whiskers 1 are made of natural wheat awn, pig bristle, horse bristle and other materials with certain flexibility and acid and alkali corrosion resista...

Abstract

The invention relates to a magnetism and wheat awn bionic dual driving device of a capsule endoscope. The magnetism and wheat awn bionic dual driving device comprises a tail whisker having an imitatedwheat awn structure, and a nesting capsule, wherein the tail whisker has certain flexibility, and is connected to a carrier ring; the carrier ring is manufactured from flexible materials having magnetism, and can be fixed to the surface of a capsule body; the nesting capsule can be dissolved by gastric acid; the nesting capsule is a layer of sugar-coats, and is used for pressing the tail whiskeron the surface of the capsule body; when the capsule endoscope remains in the stomach, the nesting capsule is dissolved by the gastric juice to expose the tail whisker; and under the effect of gastrointestinal peristaltic waves, the capsule endoscope is pushed to perform intestinal tract inspection.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a capsule endoscope magnetic and awn bionic double drive device. Background technique [0002] Since the advent of capsule endoscopy in 1997, because of its advantages of convenient examination, no trauma, no wires, no pain, no cross-infection, no influence on the normal work of patients, and expanding the field of vision of gastrointestinal examination, it has become a special tool for gastrointestinal examination. It is the preferred method for intestinal examination, which overcomes the shortcomings of traditional insertion endoscopy, such as poor tolerance, inapplicability to the elderly, infirm and critically ill. However, since the capsule endoscope is swallowed naturally and propelled by physiological peristalsis in the gastrointestinal tract, and the image is transmitted at a speed of 14 frames per second since swallowing, the capsule endoscope advances in a spira...
