Description

Technical Field

[0001] The utility model relates to the field of endoscopes, in particular to an endoscope which is easy to adjust. Background Art

[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has image sensors, optical lenses, light sources, mechanical devices, etc. It can enter the stomach through the mouth or other natural channels into the body. Endoscopes can be used to see lesions that cannot be shown by X-rays, so they are very useful to doctors.

[0003] After searching, it was found that the Chinese patent publication number CN205181292U disclosed "A medical endoscope that is easy to adjust the orientation" includes a traction tube, a lens and a light source, and is characterized in that: the traction tube is composed of an external rubber tube sleeve, an internal data transmission line and a light source line, the front end of the data transmission line is connected to the lens, the front end of the light source line is connected to the light source, and the data transmission line and the light source line are arranged to slide with each other; the inner wall of the rubber tube sleeve is provided with a slide rail, and the data transmission line and the light source line are provided with sliding edges, which are convenient for the data transmission line and the light source line to slide fixedly in the rubber tube sleeve; a high-pressure air pipe is also arranged in the traction tube; the light source and the lens are arranged as two pipelines that can slide with each other, which solves the problem that the existing endoscope has only one catheter line, which is inconvenient to observe. At the same time, the design of the slide rail and the sliding edge prevents the data transmission line and the light source line from falling off. The setting of the high-pressure air pipe enables the endoscope to remove debris and dredge the pipeline, so that the observation can be clearer and convenient for medical personnel to use;

[0004] Currently, endoscopes are in use. Since the endoscope hose needs to be bent to adjust the angle of the lens and other components, the buffer protection performance of the bent endoscope tube also needs to be improved. Utility Model Content
