Problems solved by technology

[0003] An endoscope is usually provided with an independent lighting channel in the tube body, and the light source is inserted into the front end of the endoscope through the lighting channel. Since the lighting channel needs to be added to the endoscope tube body, the diameter of the endoscope will increase, making the endoscope When the speculum passes through the narrow passage in the body, it will increase the difficulty of operation, which will undoubtedly increase the pain of the patient, and even cause secondary damage to the patient

Abstract

The invention discloses an endoscope to solve the endoscope illumination problem. The endoscope comprises a sleeve pipe, at least one part of the sleeve pipe is a light guide section, the light guidesection is a light guide tube capable of conducting light, and incident light can be emitted from the peripheral surface and / or the axial surface of the light guide tube; the light guide pipe is usedfor illuminating the interior of a cavity for inserting, so that it is convenient for an imaging device to obtain a clear image; the light guide tube is used for lighting, lighting equipment in the sleeve pipe can be omitted, the size of the sleeve pipe is reduced, and discomfort of patients when the endoscope is used is weakened.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an endoscope. Background technique [0002] After the endoscope enters the body, it uses a photographic device for observation or treatment. In order to improve the image quality and make the photographic image clearer, a light source is usually installed in the endoscope, and the light source is irradiated toward the movement direction of the endoscope, so that The imaging device is used to obtain images and observe the condition, and it is also convenient for the user to control the movement of the endoscope. [0003] An endoscope is usually provided with an independent lighting channel in the tube body, and the light source is inserted into the front end of the endoscope through the lighting channel. Since the lighting channel needs to be added to the endoscope tube body, the diameter of the endoscope will increase, making the endoscope The speculum will increase the difficul...
