Problems solved by technology

The disadvantage is that the capsule endoscope runs in the intestinal tract for a long time, generally 5 to 20 hours, or even longer
In addition, because the capsule endoscope relies on intestinal peristalsis to operate, and intestinal peristalsis has the characteristics of uneven speed, it is easy to lose the opportunity to capture some key image positions instantly
Third, in the case of large tumors or other causes of intestinal obstruction, the examination cannot be performed
Its disadvantage is that it has a large pulling force on the intestinal body, which increases the pain of the patient, and the examination is often terminated due to spasm
At the same time, it also has the disadvantages of long inspection process and difficult operation. The whole enteroscopy takes about 3 hours.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 , this embodiment includes a lens D connected with a wire F through a wire wheel E, an intima tube assembly A for advancing the lens D, and an adventitia tube assembly B sleeved outside the intima tube assembly A. The wire F passes through the center of the intima tube assembly A, and the rear end is located behind the intima tube assembly A. The function of the wire F is to transmit the image data collected by the lens D to the outside. The liquid with lubricant is filled in the annular sealing interlayer 3 .

[0021] Such as figure 2 As shown, the inner membrane tube assembly A includes a membrane tube 2, and the membrane tube 2 has an annular sealing interlayer 3, and the annular sealing interlayer 3 is filled with a liquid with a lubricant. A supporting propulsion assembly is installed in the annular sealing int...

Abstract

The invention discloses a free noninvasive endoscope pushing device which comprises an inner film tube assembly and an outer film tube assembly. The inner film tube assembly is used for pushing a lens, and the outer film tube assembly sleeves the outside of the inner film tube assembly; the inner film tube assembly and the outer film tube assembly respectively comprise liquid-filled film tubes, and the outer wall of the film tube of the inner film tube assembly is in contact with the inner wall of the film tube of the outer film tube assembly under the effects of liquid pressures; the inner wall of the outer film tube assembly is driven to be extended when the inner film tube assembly moves. The free noninvasive endoscope pushing device has the advantages that the pushing speeds can be controlled, the pushing device can be taken out instantly, and accordingly the examination operation time can be greatly shortened; sliding friction between the pushing device and the inner walls of the small intestines of patients can be prevented, and accordingly noninvasive examination can be carried out on the small intestines of the patients.

Description

[0001] technical field [0002] The invention relates to an endoscope propulsion device as a medical instrument, which is mainly used to propel a capsule endoscope to perform digestive tract inspection. technical background [0003] Existing methods of intestinal endoscopy generally include oral capsule endoscopy and enteroscopy. The patient takes a capsule endoscope (smart capsule gastrointestinal endoscope system, also known as medical wireless endoscope) orally. The capsule endoscope runs naturally through the digestive tract, ingests image data in the digestive tract, and finally discharges it through the anus. The disadvantage is that the capsule endoscope runs in the intestinal tract for a long time, generally 5 to 20 hours, or even longer. In addition, since the capsule endoscope relies on intestinal peristalsis to operate, and intestinal peristalsis has the characteristics of uneven speed, it is easy to lose the opportunity to capture some key image positions instan...
