Problems solved by technology

But this method still needs to pull the capsule out of the body with a thread in the end, and it will also make the patient feel sick and painful, and the angle of observation cannot be adjusted and controlled.
Therefore, there is no device in China that can control and adjust the movement of the capsule endoscope in the esophagus and make the patient feel no pain.

Embodiment Construction

[0021] figure 1 It is a structural diagram of a releasable and magnetically controlled thin wire tube capsule esophageal endoscope, which consists of four parts: a syringe 1, a thin wire tube 2, a vacuum chuck 3 and a capsule endoscope 4. The thin wire tube 2 in the device is a non-toxic, soft and stable tube body, one end is connected with the syringe 1, and the other end is connected with the vacuum suction cup 3, and the vacuum suction cup 3 in the device is a transparent, soft and deformable object.

[0022] When we use it, firstly pull the piston of the syringe 1 up for a short distance to make the inside of the syringe in a vacuum state, such as figure 2 At this time, the capsule endoscope 4 is subjected to the upward suction force F1 of the vacuum chuck 3, the upward friction force F2, and the vertical downward gravity F3 of the capsule endoscope 4 itself. Since the capsule endoscope 4 is small in size and light in weight, the sum of the upward F1 and F2 is much great...

Abstract

The invention provides a filament tube capsule oesophagoscope capable of being released and magnetically controlled. The filament tube capsule oesophagoscope capable of being released and magnetic controlled comprises a needle cylinder, a filament tube, a vacuum sucking disc and a capsule endoscope. The filament tube capsule oesophagoscope capable of being released and magnetic controlled is characterized in that one end of the filament tube is connected with the needle cylinder, the other end of the filament tube is connected with the vacuum sucking disc, and the capsule endoscope is a micro-camera with magnetic dipoles. According to the filament tube capsule oesophagoscope capable of being released and magnetic controlled, the speed of the capsule endoscope passing through an esophagus is controlled through the filament tube and the vacuum sucking disc, viewing angles of the capsule endoscope can be controlled freely, and the defects that a common capsule endoscope is short in dwelling time in the esophagus, high in a missing rate, single in viewing angles and the like are overcome. The filament tube capsule oesophagoscope capable of being released and magnetic controlled is simple in structure, low in cost, convenient to use and capable of greatly improving a detectable rate of esophageal diseases after being popularized and used.

Description

technical field [0001] The invention relates to a capsule endoscope, in particular to a releasable and magnetically controlled thin wire tube capsule esophagus endoscope. Background technique [0002] There are about 120 million hepatitis B surface antigen-positive patients in my country, more than 30 million chronic hepatitis B patients, and as many as 270,000 patients die of hepatitis B-related liver diseases every year. Some patients with chronic hepatitis B will develop liver cirrhosis and portal hypertension, and rupture of esophageal varices is one of the main causes of death in such patients. [0003] Esophageal cancer is also a common disease in my country, and nearly 200,000 patients die of esophageal cancer every year. Esophageal cancer refers to malignant lesions formed by abnormal proliferation of esophageal squamous epithelium or glandular epithelium. Its development generally goes through the stages of epithelial dysplasia, carcinoma in situ, and invasive car...
