Problems solved by technology

[0003] However, clinical experiments have shown that there are still some technical problems to be solved urgently in the detection of upper gastrointestinal lesions by the existing capsule endoscopy.
For example, Patent No. 201220135353.3, the invention named "Capsule Endoscopy" discloses a capsule endoscope. The patient swallows this capsule endoscope, and after the test is completed, it is excreted with feces. In order to avoid cross-infection, this The capsule endoscope is a one-time product, so that the expensive parts inside the capsule cannot be recycled for multiple times, resulting in unnecessary waste and increased testing costs for patients; secondly, the power source for the movement of the capsule endoscope in the upper gastrointestinal tract mainly relies on Provided by the flow of fluid in the upper gastrointestinal tract, medical staff cannot flexibly control its movement in the upper gastrointestinal tract; finally, the small size of this capsule endoscope will not cause discomfort in patients

Abstract

The invention discloses a traction type capsule endoscopy which comprises a capsule endoscopy body. The traction type capsule endoscopy is characterized in that one end of the capsule endoscopy body is a non-free end which is provided with a traction flexible wire, the other end of the capsule endoscopy body is a free end, and the traction flexible wire is connected with the capsule endoscopy body through a connecting mechanism. Compared with the prior art, the traction type capsule endoscopy has the advantages that direct contact of the capsule endoscopy body and the upper digestive tract is avoided so that the capsule endoscopy body can be conveniently and repeatedly used, one-time detection cost of a patient is lowered, and popularization of the capsule endoscopy at various areas is facilitated; the traction type capsule endoscopy is small in size, the outer surface is smooth, adverse reactions of the patient in the detection process are reduced to a large extent, and unnecessary damage to the upper digestive tract is avoided.

Description

technical field [0001] The invention relates to a capsule endoscope, in particular to a capsule endoscope which uses flexible wires for traction and can be recycled for multiple times, and belongs to the technical field of medical devices. Background technique [0002] Capsule endoscopy is a new type of non-invasive and painless gastrointestinal and upper gastrointestinal wireless detection system. It is composed of a capsule shaped like a pill and an in vitro image recorder to realize the detection function of the upper gastrointestinal tract. The size of the smart endoscope is small, and the patient does not need anesthesia and can move freely during the swallowing process, eliminating the pain and inconvenience caused by traditional detection methods. Due to the huge commercial benefits and application prospects of this technology, and the advantages of simple operation, painless, and no cross-infection, capsule endoscopy is favored by more and more researchers at home ...
